ORQUE ADJUSTMENT
Disconnect air hose before adjustment.
- For square drive models hold the output shaft <58> from turning, by
using a SW19 (3/4") wrench.
- For quick change chuck models hold the output shaft from turning, by
pushing locking sleeve <83> forward.
- Using Allen key <87>, turn adjusting screw <74> counterclockwise
until the stop is reached. This represents the minimum torque setting.

AINTENANCE AND
Caution!
In order to avoid failures
- check regularly the oil level of the pulse unit <44> and
- do oil change after approx. 500 hours' operation or at least every 12
months and renew gasket set <89>.
4. W , ...
HAT TO DO IF
...there is no shut-off?
- Is the dynamic air pressure too low or high?
- Has torque adjustment been checked?
- Is enough oil inside the pulse unit?
- Is it a floating connection (e.g. with extension, reduced shaft bolt)?
- Is the inside diameter of the air connectors too small?
- Is the set bolt <33> in position "min. capacity"?
...the torque scatter is too wide?
- Is the flow pressure too high?
- Is there air inside the pulse unit?
- Is the set bolt <33> in position "max. capacity"?

OTOR DISASSEMBLY
- Clamp the pistol grip <1> of the tool in a soft-jawed vise.
- Use a strap wrench to remove housing <82> counterclockwise and
pull off.
- Remove flat head screw <13> and the reverse button <14>.
- Remove retaining ring <43>.
- Use the hex of the rotor spindle <36> to clamp unit horizontally in a
vise.
- Pull off the motor.
- By applying the actuating rod <37> you can manually pull off the
switch-off unit in axial direction.
- Press rotor <36> from grooved ball bearing <27>.
<33>
ERVICE
- Turning the adjusting screw clockwise approx. 0 - 4 full turns will
adjust the tool for max. torque range: 90 - 160 Nm (66 - 118 lbf.ft).
- Improve the precision of tool switch-off by turning the set bolt <33>
in the push-button with the Allen key <88>.
- Turn the set bolt <33> counterclockwise to set the basic adjustment
(max. adjustment).
- Turn the set bolt clockwise to decrease the capacity.

ISMOUNTING THE
Disassembly should only occur if the oil filler unit <A> is
available! Pulse unit has to be at room temperature.
- Remove o-ring <80>.
- Dismounting pulse unit <44> from the housing <82>.
- Clamp the hydraulic cylinder <67> slightly in a vise with flat chops.
To avoid endangering health or the environment, study
and comply with all Federal, State and Local Regulations.
- Loosen threaded ring <45> with device <C>.
- Loosen lock screw <68>.
- Open the vise and remove the hydraulic cylinder.
- Remove lock screw <68> over an oil pan and dismount pulse unit by
applying light pressure on hydraulic rotor <58>.
Hydraulic blades are spring loaded!
- Disassemble remaining parts of the hydraulic rotor by removing the
two retaining rings <53>.
- Clean all parts.
Caution!
To maintain tool performance and minimise maintenance
costs use GARDNER-DENVER parts and recommended
lubricants only. Use of other than GARDNER-DENVER
parts releases the manufacturer from all guarantee and
warranty.
