							IMPORTANT INFORMATION ABOUT THIS MANUAL
Improper maintenance and operation are responsible for the majority of accidents
involving round head nailers. The largest portion of these could be prevented by rec-
ognizing the basic safety rules and precautions. Most accidents can be avoided if
the operator recognizes a potentially hazardous situation before it happens and by
observing appropriate safety rules and procedures as outlined in this manual.
Basic safety precautions are outlined in the SAFETYportion of this manual and
throughout text in this manual where a potential hazard might occur.
Hazards that MUSTbe avoided to prevent serious injury follow headers marked
DANGER or WARNING. These same precautions are placed as labels on the tool
itself.
NEVERuse this nailer for applications that are NOTspecified in this manual.
SAFETY WARNINGS AND PRECAUTIONS
Do not operate round head nailer anywhere fastener may contact hidden
electrical wiring.Contact with a “live” wire will make all metal parts of the
round head nailer “live.” This can result in severe electrical shock, severe burns
or death to the operator. Contact a qualified electrical contractor to ensure a safe
working environment exists.
Be aware of conduits or gas pipes.Striking a gas pipe could result in an explo-
sion causing serious injuries or even death to the operator or bystanders.
Be aware of what is behind the work piece.A fastener could travel through the
work piece and out the other side, striking a bystander resulting in serious
injury or even death.
Do not operate the round head nailer in the presence of flammable liquids, such
as gasoline, thinner, paint, or adhesives, gases or dust. Sparks created by the tool
can cause flammable materials to ignite or explode. Failure to comply with this warn-
ing could result in serious injury or even death to the operator.
Keep bystanders, children and visitors away from area where round head
nailer is being used.Distractions can result in severe injury or even death to
anyone who inadvertently gets in the way of nailing operations.
Do not use oxygen, combustible or bottled gases (such as carbon
dioxide or nitrogen) as a power source for the round head nailer.
Use only compressed air from a source as outlined in this manual.
The tool will explode resulting in severe injury or even death to the operator and
bystanders.

the requirements of American National Standards Institute (ANSI) Z87.1
and provide protection against flying particles from both front and side.
WEAR HEARING PROTECTORS:Hearing protectors should be worn to
protect the ears from loud exhaust noise produced by the air tools.
USE ONLY CLEAN, DRY COMPRESSED AIR:Never use oxygen, com-
bustible gases and any other bottled gas to operate air tools. Using these
other sources can cause the air tool to explode.
NEVER POINT THE AIR NAILER AT YOURSELF OR OTHERS:Fasteners
are under extreme pressure and can cause severe injury or even death if
misused.
DO NOT EXCEED 120 psi (8.43 kg/cm
2G).Using excessive pressure
from the power source can cause the round head nailer to explode result-
ing in severe injury or even death to the operator or bystanders. 
						

							Do not connect round head nailer to an air source capable of gen-
erating more than 200 psi (14.06 kg/cm
2 G).Over-pressurizing the
round head nailer will result in bursting, abnormal operation or
breakage of the tool. Use only clean, dry, regulated compressed air
at levels specified on the tool. Failure to comply can cause severe injury or
death to the operator or bystanders.
Do not attempt to fasten the trigger in the “ON” position.This could lead to
an accidental discharge of the round head nailer. Do not operate the round head
nailer if any portion of the tool’s operating controls are inoperable, disconnect-
ed, altered in any way or not in proper working order. Failure to comply with this
warning could result in serious injury or even death to the operator or other
bystanders.
All air compressors must comply with the requirements of ANSI
b19.3.Pressure regulators must be used to limit air pressure where
air supply pressure exceeds the tool’s rated operating pressure.
Do not carry the round head nailer with a finger on the trigger.This could lead
to an accidental discharge of the round head nailer. Do not press the trigger of
the round head nailer unless it is pressed firmly against the work piece. Do not
point the round head nailer at yourself or in the direction of another person.
Failure to comply with this warning could result in serious injury or even death
to the operator or other bystanders.
Do not tamper with the work piece contact.The work piece contact prevents
accidental discharge of the round head nailer and should never be removed or
compromised in any way. Failure to comply with this warning could result in
serious injury or even death to the operator or other bystanders.
Always disconnect air hose and remove any remaining nails:
1. When round head nailer is left unattended.
2. Before performing any maintenance or repair on the round head nailer.
3. Before attempting to clear a jam in the round head nailer.
4. Before moving the round head nailer to a new location.
Always check the overall condition of the round head nailer before using.
Check for and tighten any loose screws.Ensure all safety systems are in work-
ing condition before using the round head nailer. The round head nailer must
not operate if only the trigger is pulled or if only the work piece contact is
pressed against the work piece. The round head nailer must only be used if both
the trigger and work piece contact work at the same time.
Always use hearing protection to protect your ears against
hearing loss due to exhaust noise. Always wear proper safe-
ty glasses to prevent injuries to the eyes from fragments of
the work piece, defective nails or other debris caused by using the round
head nailer.All safety glasses must have side shields and should conform to
the requirements of the American National Standards Institute (ANSI) z87.1.
Failure to comply with this warning could lead to serious or permanent damage
to the ears as well as serious damage or permanent blindness in the eyes. 
Never carry the round head nailer by the air hose.A sudden disconnection of
the air hose could cause the round head nailer to remain charged and an acci-
dental firing could occur. Failure to comply with this warning could lead to seri-
ous injury to the operator or bystanders.
Always disconnect the power source and ensure the tool is not charged
before loading fasteners.Failure to comply with this warning could cause
severe injury or death to the operator, bystanders and severe damage to the
round head nailer.
Never use a non-relieving air coupler with the round head nailer.Always use
couplers that release any built-up charge in the round head nailer’s firing mech-
anism. A non-relieving air coupler can allow the round head nailer to discharge
a fastener while the tool is disconnected from the power source. Failure to com-
ply with this warning can result in serious or permanent injury or even death to
the operator or to bystanders.
Do not drive nails on top of other nails.Do not operate the round head nailer
at too steep of an angle. Nails can ricochet. Failure to comply with this warning
can result in serious injury or even death to the operator or bystanders.
Do not modify the round head nailer in any way.Unauthorized alterations can
jeopardize safety in the tool’s operation. Failure to follow this precaution can
result in serious injury or even death to the operator or bystanders.
On rooftops and other high locations, always move forward as you use the
round head nailer.You can easily loose your footing if moving backwards.
When nailing against a perpendicular surface, nail from the top down. This
causes less fatigue and reduces the chances of accidents.
Ensure the work area is sufficiently illuminated to operate power tools.The
work area should be clear and free of litter.

							COMPONENT INSTALLATION
Never use a non-relieving air coupler with the round
head nailer.Always use couplers that release any built-up charge in the round
head nailer’s firing mechanism. A non-relieving air coupler can allow the round
head nailer to discharge a fastener while the tool is disconnected from the
power source. Failure to comply with this warning can result in serious or per-
manent injury or even death to the operator or to bystanders.
When selecting an air compressor, it must comply with the requirements of the
American National Safety Institute - ANSI B19.3.
Choose an air compressor that can supply more than the required air pressure to
ensure optimum efficiency. Always use clean, dry compressed air with a maximum
pressure of 200 psi. Use a pressure regulator and set the pressure between 70-120
PSIG (5.0- 8.5 kg/cm
2G)). Before each use, check the pressure regulator to ensure
it is functioning within the proper pressure range.
Using an air pressure of more than 120 psi can
cause the round head nailer to malfunction or possibly explode
causing severe injury or property damage.
SELECTING A PROPER AIR HOSE
Use an air hose with the largest diameter and shortest length possible to ensure
continuous, efficient nailing operations. Using an air pressure of 70 psi (5.0
kg/cm
2G), an air hose with an inside diameter of 1/4 (6.5 mm) or greater and a hose
length of less than 6.6 ft (20 m), it is recommended that a 0.5 second interval be
allowed between each nailing. Air supply hoses shall have a minimum working pres-
sure of 150 psi (10.7 kg/cm
2G) or 150% of the maximum pressure produced by the
compressor or whichever is higher.
Low air output by the compressor or a longer hose with
a smaller inside diameter in relation to the nailing frequency may decrease
the driving capability of the air nailer.
SELECTING A QUICK DISCONNECT
1. Remove the plastic protective plug
from the tool’s air inlet.
2. Insert a 1/4 NPT male quick 
disconnect into the air inlet. Install
the female portion to the air hose.
8
Thoroughly clean and maintain the round head nailer after every use.
Lubricate moving parts to prevent rust and minimize friction-related wear. Wipe
down the entire tool and remove all dust from the moving parts. Properly store
the round head nailer in a suitable case to keep it ready for the next job.
All maintenance and repairs should be performed by an authorized repair
facility.Call 1-888-278-8092 to obtain a list of repair facilities in your area or
to make arrangements to return the tool for service.

To improve the connection between the quick disconnect and air nailer, and to help
prevent oxidation, apply PTFE tape or joint compound to the connector threads
before insertion. 
3. Snap the air hose onto the quick disconnect on the air nailer. Check for air
leaks.
LUBRICATION
To ensure maximum performance, it is recommended to install an air set (oiler, reg-
ulator, and air filter) as close as possible to the air nailer. Adjust the oiler so that
approximately one drop of oil will be released for every 50 nails.
If an air set is not used or is unavailable, oil the tool using pneumatic tool oil by plac-
ing 2 or 3 drops into the air inlet. This should be done before and after use.  For
proper lubrication, the tool must be fired several times after the oil is introduced to
the filter.
OPERATING THE ROUND HEAD NAILER 
Always use hearing protection to protect your ears against
hearing loss due to exhaust noise. Always wear proper safe-
ty glasses to prevent injuries to the eyes from fragments of
the work piece, defective nails or other debris caused by using the round
head nailer.All safety glasses must have side shields and should conform to
the requirements of the American National Standards Institute (ANSI) z87.1.
Failure to comply with this warning could lead to serious or permanent damage
to the ears as well as serious damage or permanent blindness in the eyes. 
Always disconnect the air hose before making adjustments or checking the
functionality of the air nailer.
SELECT TRIGGER ACTUATION MODE

1. Firmly grip round head nailer handle.
2. Pull and hold the round head nailer trigger.
3. Push round head nailer against work piece compressing work piece contact.
4. The round head nailer will drive nail upon contact. The round head nailer will
recoil away from the work piece as nail is driven.
ADJUSTING DEPTH OF NAILING
Be aware of material thickness when using nailer. A pro-
truding nail may cause injury.
Adjust the depth of nailing by loosening the two hex
nuts (figure 3). Move nosepiece down for a shallow-
er nail depth or up for a deeper nail depth. Once
nosepiece is adjusted, tighten hex screws. To
increase the depth of the nails when the nosepiece
is already set to its lowest setting, increase the air
pressure. To decrease the depth of nails when the
nosepiece is already set to its highest setting,
decrease the air pressure. 
Always disconnect the round head nailer before making
any adjustments to the nail depth setting.
USING THE HOOK
Always disconnect the air hose before hanging the round head nailer with the
hook.
NEVER hook the round head nailer in a high location or on an unstable platform.
LOADING NAILS INTO THE AIR NAILER
Always disconnect the air hose from the round head nailer before adding or
removing nails.
NEVER use deformed nails or nail strip. Failure to observe this precaution
can result in poor nail feeding and/or jams in the feeding mechanism.

							6. Select Single Sequential Actuation Operation. Check for leaks. Without pulling
the trigger, press the work piece contact against the work piece. The tool
MUST NOT operate. Holding the tool away from the work piece, pull trigger
and hold for 5 seconds. The tool MUST NOT operate. Repeat steps several
times. Without pulling trigger, press nailer against work piece and pull trigger.
The tool MUST operate. Release trigger. Driver MUST move up.
7. Select Contact Actuation Operation. Holding nailer away from work piece, pull
trigger. The tool MUST NOT operate. While still pulling trigger, press the nailer
against work piece. The tool MUST operate.
8. If Steps 1 through 7 function properly, prepare the tool for use. Select opera-
tion mode and load fasteners. 
9. Set the required depth of drive. 
10. Repeat these steps daily. Test again if the nailer is dropped, jammed, etc.
USING THE AIR NAILER
To drive a nail, place the work piece
contact of the round head nailer against
the work piece and pull the 
trigger. See Figure 6.
To avoid any unexpected nailings, 
perform the operation as follows:
1. Avoid placing the work piece contact
against the work piece with excessive
force.
2. Pull the trigger fully and hold it in the
fired position for 1 to 2 seconds
before releasing the trigger. This will
give the round head nailer time to
completely expend the previous nail
and build enough pressure for the next nail.
14
USING THE NO-MAR NOSEPIECE
Always disconnect the air hose before attaching the 
no-mar nosepiece.
In order to prevent the surface of the work piece from
being scratched or damaged, use the no-mar nose-
piece. Install no-mar nosepiece by pressing it into
place on the nose frame. See Figure 5. 
Store the no-mar nosepiece in place when not being
used.  
Never use a non-relieving air coupler with the round
head nailer. Always use couplers that release any built-up charge in the
round head nailer’s firing mechanism. A non-relieving air coupler can allow
the round head nailer to discharge a fastener while the tool is disconnected
from the power source. Failure to comply with this warning can result in seri-
ous or permanent injury or even death to the operator or to bystanders.
When the air hose is disconnected, the pressure reservoir in the air nailer will 
discharge removing any built-up air inside the tool.REQUIRED DAILY PREPARATION
The following steps should be performed on a daily basis to ensure the round head
nailer is operating correctly:
1. Disconnect air supply from nailer and remove fastener strip.
2. Check all screws, nuts and pins and ensure all are tight.
3. Press the pusher release button and slide back the pusher assembly
(Overriding the dry fire lockout). Press the work piece contact against a work
piece ensuring smooth movement.
4. With work piece contact against the work piece, pull trigger. The trigger must
operate smoothly.
5. Connect air supply and set regulator for 70 psi. DO NOT load a fastener strip.

Figure 6
Figure 5 
						

							CLEARING JAMS
Typically, jams are caused when a fastener or a fastener fragment becomes wedged
between the driver blade and nail guide. Using the wrong fastener can also cause jams.
TO CLEAR A JAM:
1. Disconnect the air supply and
remove the fastener strip. Leave the
pusher assembly open.
2. Loosen hex screws from back of
magazine and pull magazine back.
See Figure 9.
3. Remove jammed fastener.
4. Slide magazine back in position and
refasten hex screws (Figure 10). MAINTENANCE
STORAGE OF NAILS
Always handle nail strips and their box very carefully. If the nail strips have been mis-
handled, they may be out of shape or have breaks in the connecting strips. This will
cause the nails to feed poorly and possibly result in misfiring or jams in the air nailer.
Avoid storing nails in a very humid or hot environment or place in direct sunlight. 
OVERALL MAINTENANCE OF AIR NAILER
Always disconnect the air hose from round head nailer
before attempting any type of maintenance or visual inspection of tool.
DO NOT hold the trigger in a half-pulled position. This
could cause an unexpected nailing to occur if the work piece contact is permit-
ted to re-contact the work piece. Failure to comply could result in damage to
work piece.LOCKING AND UNLOCKING THE TRIGGER
Always move lever to the locked position immediately
after using the nailer to prevent unintended firing of fastener.
The round head nailer is equipped with a trigger
lock to prevent operation of the tool when not
actively being used.  To lock trigger, move trigger
lock lever up to the locked position. To unlock trig-
ger in preparation for use, move the trigger lock
lever down to the unlocked position (Figure 7).CHANGING DIRECTION OF EXHAUST AIR
The direction of exhaust air on the air nailer can be
directed 360˚ degrees by placing hand on exhaust
cover and turning. See Figure 8.
