Overhaul
WARNING Overspeed could result in serious injury or death
If speed governor is used, check that correct speed governor is assem-
►
bled. 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 grinder
For preventive maintenance, the grease in the angle gear should be changed af-
ter roughly 1000 hours of operation. See the directions under Lubrication.
The entire machine should be checked regularly at six-months 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.
Keep the magnetic oil plug (in the angle gear housing) clean.
Clean the motor parts and apply a thin layer of air lubrication oil onto the
vanes and inner surface of cylinder and end plates.
Assemble the motor and check that it is running free. Add two drops of oil
through the air inlet and run the motor at idling speed for 5-10 seconds.

Ergonomic guidelines
Consider your workstation as you read through this list of general ergonomic
guidelines and see if you can identify areas for improvement in posture, compo-
nent placement, or work environment.
• Take frequent breaks and change work positions frequently.
• Adapt the workstation area to your needs and the work task.
• Adjust for convenient reach range by determining where parts or tools
should be located to avoid static load.
• Use workstation equipment such as tables and chairs appropriate for the
work task.
• Avoid work positions above shoulder level or with static holding during as-
sembly operations.
• When working above shoulder level, reduce the load on the static mus-
cles 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, particularly for operations requir-
ing a degree of force.
