high torque and long tightening times. If the machine
is not working properly, it should immediately be
taken away for inspection.
The strainer at the air inlet and the exhaust silencer
should be cleaned frequently or replaced in order to
prevent clogging, which decreases the capacity.
At the overhauls, all parts should be cleaned accur-
ately and defective or worn parts should be replaced.
A
All o-rings should be greased before assem-
bling; especially important are the o-rings in
the pulse unit.
Disassembling /assembling
It is important that the machines threaded connec-
tions are tightened properly; i.e. in accordance with
the specifications on the exploded views.
Cleaning
Clean all parts, not electrical, thoroughly in white
spirit or similar cleaning agent. To prevent clogging
and decreased power, it could be necessary to clean
the strainer (if used) and the exhaust filter between
the overhauls.
Inspection
After the cleaning, inspect all parts. Damaged and
worn parts should be replaced.
Lubrication
Lubricate specially gears, valve and clutch with
grease containing molybdenum disulphide (e.g.
Molykote BR2 Plus). Lubricate o-rings and threaded
connections with grease before assembling.

Ergonomic guidelines
) Take frequent breaks and change work positions
1
frequently.
) Adapt the workstation area to your needs and the
2
work task.
• Adjust for convenient reach range by determin-
ing where parts or tools should be located to
avoid static motion.
• Use workstation equipment such as tables and
chairs appropriate for the work task.
) Avoid work positions above shoulder level or with
3
static holding during assembly operations.
• When working above shoulder level, reduce
the load on the static muscles by reducing the
weight of the tool, using for example torque
arms, hose reels or weight balancers. You can
also reduce the load on the static muscles by
holding the tool close to the body.
• Make sure to take frequent breaks.
• Avoid extreme arm or wrist postures, particu-
larly for operations requiring a degree of force.
) Adjust for convenient field of vision by minimiz-
4
ing movement of the eyes and head during the
work task.
) Use the appropriate lighting for the work task.
5
) Select the appropriate tool for the work task.
6
) Use ear protection equipment in noisy environ-
7
ments.
) Use high-quality inserted tools or consumables to
8
minimize exposure to excessive levels of vibra-
tions.
) Minimize exposure to reaction forces.

• When cutting:
A cut-off wheel can get stuck if the wheel is
either bent or if it is not guided properly. Make
sure to use correct flanges for cut-off wheels
and avoid bending the wheel during cut-off
operation.
• When drilling:
The drill might stall when the drill bit breaks
through. Makes sure you use support handles
if the stall torque is too high. The safety stand-
ard ISO11148 part 3 recommends to use
something to absorb the reaction torque above
10 Nm for pistol grip tools and 4 Nm for
straight tools.
• When using direct driven screw or nutrunners:
Reaction forces depend on tool setting and joint
characteristics. The ability to bear reaction
forces depends on the operator's strength and
posture. Adapt the torque setting to the operat-
or's strength and posture and use a torque arm
or reaction bar if the torque is too high.
