Maintenance instructions
Service recommendations
Preventive maintenance is recommended at regular intervals. See the detailed
information on preventive maintenance. If the product is not working properly,
take it out of service and inspect it.
If no detailed information about preventive maintenance is included, follow
these general guidelines:
• Clean appropriate parts accurately
• Replace any defective or worn parts
Overhaul
WARNING Overspeed could result in serious injury or death
If governor is used, check that correct governor is assembled. Careless
►
handling may put it out of order
Do not disassemble security parts, e.g. speed governor or overspeed shut-
►
off. These parts must be completely replaced when damaged
Always check the free speed of the machine after service. See Section
►
Preparation before using the die grinder
The entire machine should be checked regularly at six-month intervals. If it is in
heavy duty service or not running properly it should be taken out of service
more often for inspection.
The strainer at the air inlet should be cleaned frequently to prevent clogging and
decreased capacity.
Lubrication instructions
Rust protection and cleaning
Water in the compressed air can cause rust. To prevent rust we strongly recom-
mend to install an air dryer.
Water and particles can cause sticking of vanes and valves. This can be pre-
vented by installing an air filter close to the product to avoid pressure drop.
Before longer standstills always protect your tool by adding a few drops of oil
into the air inlet. Run the tool for 5–10 seconds and absorb any access oil at the
air outlet in a cloth.
NOTICE Do not try to clear the air path using sharp tools.
The air inlet is equipped with a strainer. If this is punctured, foreign objects
may harm the valves, resulting in overspeed.
