Too much oil in the pulse unit implies a low pulse frequency
and slow tightening.
Too little oil in the pulse unit implies a high pulse frequency
and there will be a risk of a decreasing tightening torque. In partic-
ular at the first tightening after a break the machine might race.
Use Hydraulic Oil : 22 cST / 40 °C (ISO VG22). Running the
machine with too little oil may damage the pulse unit. After the
refill – Check the tightening torque, see Service instructions.
Rust protection and internal cleaning
Water in the compressed air, dust and wear particles cause rust
and sticking of vanes, valves etc. An air filter should be installed
close to the machine (see 'Air quality'). Before longer standstills,
flush with oil (some drops) into the air inlet, run the machine for
5-10 seconds when absorbing the oil in a cloth.
Service instructions
Overhaul and preventive maintenance is recommended at regular
intervals once per year or after maximum 250.000 tightening de-
pending on which occurs sooner. More frequent overhaul may be
needed, specially changing oil in the pulse unit, if used at 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 accurately and de-
fective or worn parts (i.e. O-rings, vanes) should be replaced.
A
All o-rings should be greased before assembling; especially
important are the o-rings in the pulse unit.
Disassembling /assembling
It is important that the machines threaded connections 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.

All values are current as of the date of this publication. For the
latest information please visit www.desouttertools.com.These de-
clared values were obtained by laboratory type testing in accord-
ance with the stated standards and are suitable for comparison with
the declared values of other tools tested in accordance with the
same standards. These declared values are not adequate for use in
risk assessments and values measured in individual work places
may be higher. The actual exposure values and risk of harm exper-
ienced by an individual user are unique and depend upon the way
the user works, the workpiece and the workstation design, as well
upon the exposure time and the physical condition of the user.
We, Desoutter, cannot be held liable for the consequences of
using the declared values, instead of values reflecting the actual
exposure, in an individual risk assessment in a work place situation
over which we have no control. This tool may cause hand-arm
vibration syndrome if its use is not adequately managed. An EU
guide to managing hand-arm vibration can be found at ht-
