SAFETY 
IMPORTANT:   DO NOT OPERATE THE TOOL BEFORE READING THESE INSTRUCTIONS. 
FAILURE TO DO SO MAY RESULT IN PERSONAL INJURY OR DAMAGE TO THE 
TOO
L. 
This tool is intended for use with threaded fasteners.  Any other use is\
 not recommended.  
The use of ear protectors is recommended.  
Do not use tool in potentially explosive atmosphere as these tools conta\
in grease, which may cause an 
explosion hazard in the presence of pure oxygen.  These tools also contain aluminium al\
loy components 
which may cause a hazard in certain explosive environments.  
Be aware of unexpected tool movement due to reaction forces as this may \
cause injuries.  Failure of the 
driv e square may also cause unexpected tool movement. 
Isolate the tool from all energy sources before changing or adjusting th\
e drive square or socket. 
There is a risk of crushing between the reaction bar and work piece.  
Keep hands away from reaction bar. 
Keep hands away from tool output. 
Keep loose clothing, hair, etc. from being caught in any rotating part o\
f the tool.
  
These tools require a reaction bar.  See section on Torque Reaction.  
Ensure all hoses are correctly fitted before switching on the ma ins air supply.  This avoids the risk of 
injury by whipping air hoses.  
Use only sockets and adaptors which are in good condition and are intend\
ed for use with power tools.  
Pneutorque® Wrenches are non impacting, torque controlled bolt tighte\
ning tools and must always be 
operated with the following: - 
· Clean dry air supply with a minimum flow of 19 litres/sec (40 CFM).
· Air Regulator and optional Lubricator Unit 1/2” Bore (12 mm).
· Impact or high quality sockets.
· Reaction Arm.

INTRODUCTION 
The  Pneutorque ® 
 52mm series are air driven power tools designed for applying torque to \
threaded 
fasteners.  There are models to cover torque capacities of 600 N.m and 1\
000 N.m.  These models are 
available in 2 types:  
Stall Tool  
These tools use the air pressure set on  an external pressure regulator to determine the sta ll torque. 
Stall Tool with Internal Regulator  
These tools use an in -built pressure regulator to control the stall torque.  This allows the t\
ool to be set 
without the need for a separate external pressure  regulator.

FEATURES AND FUNCTIONS 
REPLACEABLE DRIVE SQUARE  
All tools are fitted with a ¾” (19mm) dri ve square that can easily be replaced.  A 1” drive square (Part 
Code 18545) is also available.  
TRIGGER  
The trigger controls the flow of air.  The more the trigger is pressed t\
he more air flows into the tool.  This 
allows for slow positioning of socket and  reaction plate.  Once positioning is complete, the trigger must be 
fully depressed for correct torque application.  
CLOCKWISE / COUNTER-CLOCKWISE SELECTOR  
Tools fitted with this option can be used for releasing bolts as well as\
 tightening.  The gearing insi de the 
housing is biased towards counter-clockwise drive to give a higher torque for releasing the fastener. 
LIFTING BRACKET  
The metal bracket  can be used to suspend the tool from a balancer. 
SET UP INSTRUCTIONS 
WARNING:  TO AVOID HAZARD FROM WHIPPING  AIR HOSES MAKE ALL 
CONNECTIONS TO THE TOOL BEFORE TURNING ON THE AIR 
SUPPLY. 
Make sure all air hoses are clean and free from dirt. 
1. Connect the tool air inlet hose (C) to the outlet side of the pressure\
 regulator unit (B), observing air flow
direction arrows.  Use a ½” bore hose with a maximum length of 3m.
TIP.  To connect the air inlet hose to a 1/2” bore hose use a ½” BSP \
Male/Male connector.  A pair of 
spanners will be required to perform this task (22mm (7/8”) A/F an\
d 24mm (15/16”) A/F open-
ended spanners)  2.
Connect the inlet side of the pressure regulator unit (B) to the mains\
 air supply (A) using a minimum
hose size of ½” bore (12mm).  Avoid using ½” bore hoses of\
 longer than 5 meters from the supply to
the pressure regulator unit as this will reduce  the performance of the tool.

3. If running the tool with oil, check the oil level in the lubricator and \
fill to the correct level if required. (see
MAINTENANCE section)
TIP.  These tools have been designed to run with a clean, dry, unlubricated air supply if required, but 
this is not essential. It is best to run a tool with unlubricated air fr\
om new as this avoids early oil 
deposits solidifying and clogging the vane slots.  4.
Fit reaction plate (D) over drive square to engage reaction splines.  \
Fit circlip (#26588) supplied.
5. Fit lifting bracket (E) into two holes in the side of the handle.
NOTE:  LIFTING BRACKET SECURING SCREWS MUST BE TORQUED UP TO 5 N.M.
TIP.  The hanger should be used only in conjunction with a suitable balancer. \
 If the tool is  to be used 
without a balancer or hanging device there is no need to fit the hanger \
to the tool.

TORQUE REACTION _________________________________________________________  
When the Pneutorque® is in operation the reaction arm rotates in the \
opposite direction to the output 
drive square and must be allowed to  rest squarely against a solid object or surface adjacent to the bolt to\
 
be tightened. (See figure 2). 
WARNING:  ALWAYS KEEP HANDS CLEAR OF THE REACTION ARM WHEN THE TOOL IS IN 
USE OR SERIOUS INJURY MAY RESULT.  Figure 2a (Cl
ockwise)  Figure 2b (Counter-clockwise) 
WARNING:  CARE MUST BE TAKEN TO ENSURE THAT THE REACTION ARM IS 
ONLY USED WITHIN THE LIMITATIONS SHOWN IN FIGURE 3.  
For special applications or where extra deep sockets must be used the st\
andard arm may be extended 
but only within the limitations shown on Figure 3.  
Alternative reaction devices are available.  
WARNING:  FAILURE TO OBSERVE THE LIMITATIONS SHOWN IN FIGURE 3 
WHEN MODIFYING STANDARD REACTION ARMS MAY RESULT IN  
PREMATURE WEAR OR DAMAGE TO THE TOOL. 
Standard drive square extensions MUST NOT be used as these will cause serious\
 damage to the tool 
output drive. A range of nose extensions is available for applications w\
here access is restricted.  These 
are designed to support the final drive correctly.  Figure 3

SETTING TORQUE FOR BOLT  TIGHTENING______________________________________  
STALL TOOL – MODEL 18039 AND 18040 ________________________________________  
These tools use the air pressure set on an external pressure regulator u\
nit to determine the stall torque.  
They are supplied with an Air Pressure Graph which relates torque output\
 to air pressure.  Set the torque 
output as follows: - 
1. Ensure the Clockwise/Counter-clockwise Selector (if fitted) is correctly set.
2. Establish the air pressure required using the Air Pressure Graph.
3. With the tool running, adjust the pressure regulator until the correct f\
igure is shown  on the gauge.
IMPORTANT:  THE WRENCH MUST BE FREE RUNNING WHILE ADJUSTING THE AIR 
PRESSURE TO GIVE THE CORRECT SETTING. 
STALL TOOL FITTED WITH TORQUE REGULATOR – MODEL 18041 AND 18042 ________ 
The tool can be set in one of two ways.  
A. The tool can be set against th e Air Pressure Graph in the same way as the stall tool without the
internal regulator as long as the regulator valve is fully open. (This \
is factory set fully open).  For this
method follow the same setup as for Models 18039 and 18040.
B. To set the torque regulator a suitable calibration device will be required. (see Glossary o\
f Terms)  Set
the tool by the following procedure.
1. Ensure the Clockwise/Counter-clockwise
Selector (if fitted) is correctly set.
2. If the tool is connected up to the mains air
supply, s witch off the supply and press the
trigger to release any air trapped between
the pressure regulator and the tool.
Remove the air hose from the tool.
3. Fit the adjusting tool J2364 into the air inlet
tube until the box spanner engages onto
the locknut (A). L oosen the locknut (C) by
90 degrees.
4. Engage the screwdriver (D) into the slot in
the end of the valve body (B).  Rotate
screwdriver (D) to change torque setting.
5. Tighten locknut (C) and remove adjusting
tool.
6. Re-attach the tool to the air supply and
check the stall torque against a calibration
device.  This process may take several
adjustments to achieve the final setting.
7. The tool is now ready for use.
