Safety and operating instructions
• Never put your hand on or close to the reaction bar while the machine is
being used.
Maintenance
For maximum performance
It is important to lubricate regularly to get maximum performance and trouble-
free operation. The motor should be lubricated with oil; i.e. drops of oil can be
dropped either into the compressed air or directly into the air inlet.
The trigger, planetary gears, needle bearings and ball bearings should be lubri-
cated with grease during the regular overhaul of the machine.
The angle gear and clutch must be lubricated using grease that contains molyb-
denum disulphide: Molykote BR2 Plus, for example, 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').
Reporting, RE – signal
Reporting (RE) machines supply an air signal that can be connected to a moni-
toring instrument that counts the number of approved tightening and detects
premature shut-off and rehits and other irregularities.
Service instructions
Overhaul and preventive maintenance is recommended at regular intervals once
per year or after maximum 250.000 tightening depending 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 fre-
quently or replaced in order to prevent clogging, which decreases the capacity.
At the overhauls, all parts should be cleaned accurately and defective 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.
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.
