The angle gear and clutch must be lubricated using grease that
contains molybdenum disulphide: Molykote BR2 Plus, for ex-
ample, or an equivalent brand.
Use lubricants of good quality. The oils and greases mentioned
in the table are examples of lubricants which are recommended.
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").
Service instructions
Overhaul and preventive maintenance is recommended at regular
intervals once per year or after maximum 250.000 tightenings de-
pending on which occurs sooner. More frequent overhaul may be
needed, if used at high torque and long tightening times. If the
machine not is 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.
Disassembling / assembling
It is important that the machines threaded connections are tightened
properly; i.e. in accordance with the specifications on the exploded
views.
A
Lubricate o-rings and threaded connections with grease before
assembling.
Cleaning
Clean all parts 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). Please see
exploded views and fig. under Service instructions.
