WARNING
WARNING
Inhalation of certain dusts, especially 
organic dusts such as mold or pollen, 
can cause susceptible persons to have 
an allergic or asthmatic reaction.
Substantial or repeated inhalation of 
dust and other airborne contaminants, in 
particular those with a smaller particle size, may cause respiratory or other 
illnesses. This includes wood dust, 
especially from hardwoods, but also 
from some softwoods such as Western 
Red Cedar. Control dust at the source 
where possible. Use good work 
practices, such as such as always 
cutting with a properly sharpened chain 
(which produces wood chips rather than 
fine dust) and operating the unit so that 
the wind or operating process directs 
any dust raised by the power tool away 
from the operator. Follow the 
recommendations of EPA / OSHA / 
NIOSH and occupational and trade 
associations with respect to dust 
("particulate matter"). When the 
inhalation of dust cannot be 
substantially controlled, i.e., kept at or 
near the ambient (background) level, the 
operator and any bystanders should 
wear a respirator approved by NIOSH / 
MSHA for the type of dust encountered.
WARNING
Breathing asbestos dust is dangerous 
and can cause severe or fatal injury, 
respiratory illness or cancer. The use 
and disposal of asbestos-containing 
products have been strictly regulated by 
OSHA and the Environmental Protection 
Agency. If you have any reason to 
believe that you might be cutting 
asbestos, immediately contact your 
employer or a local OSHA 
representative.
WARNING
This power tool has a large range. In 
order to reduce the risk of personal or 
even fatal injury to bystanders from 
falling objects or inadvertent contact with the moving chain of your power tool 
always keep bystanders at least 50 feet 
(15 m) away when the power tool is 
running.
WARNING
Even though bystanders should be kept 
away from the running saw, never work 
alone. Keep within calling distance of 
others in case help is needed.
Stop the engine immediately if you are 
approached.
DANGER
Electricity can jump from one point to 
another by means of arcing. Higher 
voltage increases the distance electricity  As soon as the engine is 
running, this product gen-
erates toxic exhaust 
fumes containing chemi-
cals, such as unburned 
hydrocarbons (including 
benzene) and carbon 
monoxide, that are 
known to cause respira-
tory problems, cancer, 
birth defects, or other 
reproductive harm. Some 
of the gases (e. g. carbon 
monoxide) may be color-
less and odorless. To 
reduce the risk of serious 
or fatal injury / illness 
from inhaling toxic fumes, 
never run the machine 
indoors or in poorly venti-
lated locations. If exhaust 
fumes become concen-
trated due to insufficient 
ventilation, clear obstruc-
tions from work area to 
permit proper ventilation 
before proceeding and / 
or take frequent breaks to 
allow fumes to dissipate 
before they become 
concentrated.
Your power tool is not 
insulated against electric 
shock. To reduce the risk 
of electrocution, never 
operate this power tool in 
the vicinity of any wires or 
cables (power, etc.) 
which may be carrying 
electric current.

10 can arc. Electricity can also move 
through branches, especially if they are 
wet. Maintain a clearance of at least 
50 feet (15 m) between the pole pruner 
(including any branches it is contacting) 
and any electrical line carrying live 
current. Before working with less 
clearance, contact your electric utility 
and make sure the current is turned off.
Operating Instructions
WARNING
Do not operate your power tool using the 
starting throttle position, as you do not 
have control of the engine speed.
In the event of an emergency, switch off 
the engine immediately – move the slide 
control / stop switch to 0 or STOP.
WARNING
To reduce the risk of cut injuries, keep 
hands and feet away from the saw 
chain. Never touch a moving chain with 
your hand or any other part of your body. 
The saw chain continues to move for a 
short period after the throttle trigger is 
released (inertia effect).
Accelerating the engine while the chain 
is blocked increases the load and will 
cause the clutch to slip continuously. 
This may result in overheating and 
damage to important components (e. g. 
clutch, polymer housing components) – 
which can then increase the risk of injury 
from the chain moving while the engine 
is idling.
WARNING
If the chain becomes clogged, always 
turn off the engine and make sure the 
chain has stopped before cleaning.
Make sure that the saw chain does not 
touch any foreign materials such as 
rocks, fences, nails and the like. Such 
objects may be flung off and injure the 
operator or bystanders, or damage the 
saw chain.
WARNING
Prior to limbing, clear the working area 
from interfering limbs and brush. Then, 
establish an escape area away from 
where the cut limbs can fall, and remove 
all obstacles.
Keep work area clear – move away 
fallen limbs. Place all tools and 
equipment at a safe distance from the 
branches being limbed, but not in the 
escape area.
WARNING
Always observe the general condition of 
the tree. Look for decay and rot in the 
trunk and branches. If it is rotted inside, 
it could snap and fall toward the operator 
while being cut. Also look for broken or 
dead branches which could vibrate 
loose and fall on the operator. If branch 
is thick or heavy, make a shallow relief 
cut on the bottom of the branch before 
cutting down from the top to help prevent 
splitting of the branch.
WARNING
To reduce the risk of severe or even fatal 
injury from falling objects do not cut 
vertically above your body. Hold the pole 
pruner at an angle of not more than 60° 
from the horizontal level (see picture). 
Objects may fall in unexpected 
directions. Do not stand directly 
underneath the limb being cut!
Watch for falling wood! As soon as the 
limbed branch starts to fall, step aside 
and keep a sufficient distance away from 
the falling wood.
WARNING
Always pull the unit out of the cut with 
the chain running to reduce the 
possibility of pinching the cutting 
attachment. Don't put pressure on the 
pole pruner when reaching the end of a 
cut. The pressure may cause the bar

11 and rotating chain to pop out of the cut or 
kerf, go out of control and strike some 
other object.
If the bar becomes pinched and caught 
in the branch so that the chain can no 
longer move, shut off the pole pruner 
and carefully move the branch to open 
the pinch and release the bar.
WARNING
If a rotating saw chain strikes a rock or 
other hard object, sparks may be 
created, which can ignite flammable 
materials under certain circumstances. 
Flammable materials can include dry 
vegetation and brush, particularly when 
weather conditions are hot and dry. 
When there is a risk of fire or wildfire, do 
not use a power tool around flammable 
materials or around dry vegetation or 
brush. Contact your local fire authorities 
or the U.S. Forestry Service if you have 
any question about whether vegetation 
and weather conditions are suitable for 
the use of a pole pruner.
WARNING
Never modify your muffler. Any 
modification could cause an increase in 
heat radiation, sparks or sound level, 
thereby increasing the risk of fire, burn 
injury or hearing loss. You may also 
permanently damage the engine. Have 
your muffler serviced and repaired by 
your STIHL servicing dealer only.
WARNING
The muffler and other parts of the engine 
(e.g. fins of the cylinder, spark plug) 
become hot during operation and remain 
hot for a while after stopping the engine. To reduce risk of burns, do not touch the 
muffler and other parts while they are 
hot. Keep the area around the muffler 
clean. Remove excess lubricant and all 
debris such as pine needles, branches 
or leaves. Let the engine cool down 
sitting on concrete, metal, bare ground 
or solid wood (e.g. the trunk of a felled 
tree) away from any combustible 
substances.
WARNING
An improperly mounted or damaged 
cylinder housing or a 
damaged/deformed muffler shell may 
interfere with the cooling process of the 
muffler. To reduce the risk of fire or burn 
injury, do not continue work with a 
damaged or improperly mounted 
cylinder housing or a 
damaged/deformed muffler shell.
Your muffler is furnished with a spark 
arresting screen designed to reduce the 
risk of fire from the emission of hot 
particles. Never operate your unit with a 
missing or damaged spark arresting 
screen. If your gas/oil mix ratio is correct 
(i.e., not too rich), this screen will 
normally stay clean as a result of the 
heat from the muffler and need no 
service or maintenance. If you 
experience loss of performance and you 
suspect a clogged screen, have your 
muffler maintained by a STIHL servicing 
dealer. Some state or federal laws or 
regulations may require a properly 
maintained spark arrestor for certain 
uses. See the "Maintenance, Repair and 
Storing" section of these Safety 
Precautions. Remember that the risk of 
a brush or forest fire is greater in hot or 
dry conditions.
WARNING
Reactive Forces
WARNING
Reactive forces may occur any time the 
chain is rotating.The force used to cut 
wood can be reversed and work against 
the operator. If the rotating chain is 
suddenly stopped by contact with any 
solid object such as a branch or is 
pinched, the reactive forces may occur 
instantly. These reactive forces may 
result in loss of control, which, in turn, 
may cause personal injury. An 
understanding of the causes of these 
reactive forces may help you avoid the 
element of surprise and loss of control. Some STIHL power tools 
are equipped with a cata-
lytic converter, which is 
designed to reduce the 
exhaust emissions of the 
engine by a chemical pro-
cess in the muffler. Due 
to this process, the muf-
fler does not cool down 
as rapidly as conven-
tional mufflers when the 
engine returns to idle or 
is shut off. To reduce the 
risk of fire and burn inju-
ries when using a 
catalytic converter, 
always set your power 
tool down in the upright 
position and never locate 
it where the muffler is 
near dry brush, grass, 
wood chips or other com-
bustible materials while it 
is still hot.

12 Because of the design of the pole 
pruner, the reactive forces experienced 
when working with it are generally not as 
severe as those encountered with a 
chainsaw. Nevertheless, you should 
always maintain a proper grip and good 
footing to control the power tool when 
you experience such forces.
The most common reactive forces are:
–kickback,
–pushback,
–pull-in.
Kickback
Kickback may occur when the moving 
saw chain near the upper quadrant of 
the bar nose contacts a solid object or is 
pinched.
The reaction of the cutting force of the 
chain causes a rotational force on the 
chainsaw in the direction opposite to the 
chain movement. This may cause the 
bar to move upward.To Avoid Kickback
The best protection from kickback is to 
avoid kickback situations:
1.B e  a w a r e  o f  t h e  l o c ation of the guide 
bar nose at all times.
2.Never let the nose of the guide bar 
contact any object. Do not cut limbs 
with the nose of the guide bar. Be 
especially careful near wire fences 
and when cutting small, tough 
limbs, which may easily catch the 
chain.
3.Cut only one limb at a time.
A = Pull-in
Pull-in occurs when the chain on the 
bottom of the bar is suddenly stopped 
when it is pinched, caught or encounters 
a foreign object in the wood. The 
reaction of the chain pulls the saw 
forward.
Pull-in frequently occurs when the chain 
is not rotating at full speed before it 
contacts the wood.
To Avoid Pull-in
1.Be alert to forces or situations that 
may cause material to pinch the 
chain at the bottom of the bar.
2.Always start a cut with the chain 
rotating at full speed.B = Pushback
Pushback occurs when the chain on the 
top of the bar is suddenly stopped when 
it is pinched, caught or encounters a 
foreign object in the wood. The reaction 
of the chain may drive the saw rapidly 
straight back toward the operator. 
Pushback frequently occurs when the 
top of the bar is used for cutting.
To Avoid Pushback
1.Be alert to forces or situations that 
may cause material to pinch the 
chain at the top of the bar.
2.Do not cut more than one limb at a 
time.
3.Do not twist the bar when 
withdrawing it from an underbuck 
cut because the chain can pinch.
MAINTENANCE, REPAIR AND 
STORING
Maintenance, replacement, or repair of 
the emission control devices and 
systems may be performed by any 
nonroad engine repair establishment or 
individual. However, if you make a

parts were used, STIHL may deny 
coverage.
WARNING
Use only identical STIHL replacement 
parts for maintenance and repair. Use of 
non-STIHL parts may cause serious or 
fatal injury.
Strictly follow the maintenance and 
repair instructions in the appropriate 
sections of your instruction manual. 
Please refer to the maintenance chart in 
this manual.
WARNING
Always stop the engine and make sure 
that the chain is stopped before doing 
any maintenance or repair work or 
cleaning the power tool. Do not attempt 
any maintenance or repair work not 
described in your instruction manual. 
Have such work performed by your 
STIHL servicing dealer only.
Wear gloves when handling or 
performing maintenance on the cutting 
attachment.
WARNING
Use the specified spark plug and make 
sure it and the ignition lead are always 
clean and in good condition. Always 
press spark plug boot snugly onto spark 
plug terminal of the proper size. (Note: If 
terminal has detachable SAE adapter 
nut, it must be securely attached.) A 
loose connection between spark plug 
terminal and the ignition wire connector 
in the boot may create arcing that could 
ignite combustible fumes and cause a 
fire.
WARNING
Never test the ignition system with the 
ignition wire boot removed from the 
spark plug or with a removed spark plug, 
since uncontained sparking may cause 
a fire.
WARNING
Do not operate your power tool if the 
muffler is damaged, missing or modified. 
An improperly maintained muffler will 
increase the risk of fire and hearing loss. 
Your muffler is equipped with a spark-
arresting screen to reduce the risk of 
fire; never operate your power tool if the 
screen is missing, damaged or clogged. 
Remember that the risk of a brush or 
forest fire is greater in hot or dry 
weather.
In California, it is a violation of § 4442 or 
§ 4443 of the Public Resources Code to 
use or operate gasoline-powered tools 
on forest-covered, brush-covered or 
grass-covered land unless the engine’s 
exhaust system is equipped with a 
complying spark arrester that is 
maintained in effective working order. 
The owner/operator of this product is 
responsible for properly maintaining the 
spark arrester. Other states or 
governmental entities/agencies, such as 
the U.S. Forest Service, may have 
similar requirements. Contact your local 
fire agency or forest service for the laws 
or regulations relating to fire protection 
requirements.
WARNING
Keep the chain, bar and sprocket clean; 
replace worn sprockets or chains. Keep 
the chain sharp. You can spot a dull chain when easy-to-cut wood becomes 
hard to cut or burn marks appear on the 
wood. Keep chain at proper tension.
Tighten all nuts, bolts and screws except 
the carburetor adjustment screws after 
each use.
For maintenance items please also refer 
to the maintenance chart in this manual.
Do not clean your machine with a 
pressure washer. The solid jet of water 
may damage parts of the machine.

NPut on the shoulder strap.
Cutting Sequence
To allow branches a free fall, always cut 
the lower branches first. Prune heavy 
branches (large diameter) in several 
controllable pieces.
WARNING
Never stand directly underneath the 
branch you are cutting – be wary of 
falling branches. Note that a branch may 
spring back at you after it hits the ground 
– risk of injury.
Disposal
Do not throw cuttings into the garbage 
can – they can be composted.
Working Techniques
Hold the control handle with your right 
hand, and the shaft with your left hand. 
Your left arm should be extended to the 
most comfortable position.HT 100, HT 130
Always hold the shaft with your left hand 
in the area of the handle hose.
The shaft should always be held at an 
angle of 60° or less.
The least tiring working position is a tool 
angle of 60°.
Any lesser angle may be used to suit the 
situation concerned.Cross-cut
To avoid pinching the bar in the cut, 
position the cutting attachment with the 
hook against the branch and then 
perform the cross-cut from the top 
downwards.
Relieving cut
To avoid tearing the bark on thick 
branches, always start by performing a 
relieving cut (1) on the underside of the 
branch.

cut.
Flush-cutting thick branches
If branch diameter is more than 
4 in (10 cm), first 
Nperform undercut (3) and then 
cross-cut at a distance of about 
8 in./20 cm (A) from the final cut. 
Then carry out the flush-cut (4), 
starting with a relieving cut and 
finishing with a cross-cut.Cutting above obstacles
The unit's long reach makes it possible 
to prune branches that are overhanging 
obstacles, such as rivers or lakes. The 
tool angle in this case depends on the 
position of the branch.
Cutting from a lift bucket
The unit's long reach enables cutting to 
be performed next to the trunk without 
the risk of the lift bucket damaging other 
branches. The tool angle in this case 
depends on the position of the branch.
30° angle drive (special accessory)
The angle drive keeps the cutting 
attachment at an angle of 30° to the 
drive tube.
The angle drive may be adjusted on the 
drive tube to the following positions only:
1For cross-cutting vertical branches 
and bushes.
2For a better view of the cutting

16 A cutting attachment consists of the saw 
chain, guide bar and chain sprocket.
The cutting attachment that comes 
standard is designed to exactly match 
the pole pruner.
–The pitch (t) of the saw chain (1), 
chain sprocket and the nose 
sprocket of the Rollomatic guide bar 
must match.
–The drive link gauge (2) of the saw 
chain (1) must match the groove 
width of the guide bar (3).
If non-matching components are used, 
the cutting attachment may be damaged 
beyond repair after a short period of 
operation.
Chain scabbard
Your pole pruner comes standard with a 
chain scabbard that matches the cutting 
attachment.
If you use guide bars of different lenghts 
on the pole pruner, the length of the 
chain scabbard must be matched to the 
guide bar to reduce the risk of injury. It 
should cover the full length of the guide 
bar.
The length of the matching guide bars is 
marked on the side of the chain 
scabbard.

unleaded gasoline and the STIHL two-
stroke engine oil at a mix ratio of 50:1.
Your engine requires a mixture of high-
quality gasoline and two-stroke air 
cooled engine oil.
Use mid-grade unleaded gasoline with a 
minimum octane rating of 89 ((R+M)/2) 
and no more than 10% ethanol content.
Fuel with a lower octane rating may 
increase engine temperatures. This, in 
turn, increases the risk of piston seizure 
and damage to the engine.
The chemical composition of the fuel is 
also important. Some fuel additives not 
only detrimentally affect elastomers 
(carburetor diaphragms, oil seals, fuel 
lines, etc.), but magnesium castings and 
catalytic converters as well. This could 
cause running problems or even 
damage the engine. For this reason 
STIHL recommends that you use only 
high-quality unleaded gasoline!
Gasoline with an ethanol content of 
more than 10% can cause running 
problems and major damage in engines 
and should not be used.
For further details, see 
www.STIHLusa.com/ethanol
The ethanol content in gasoline affects 
engine running speed – it may be 
necessary to readjust the carburetor if 
you use fuels with various ethanol 
contents.
