►
Maintain a balanced body position and firm foot-
ing
►
React quickly to excessive vibration due to dam-
aged, or improperly mounted insert tool
►
Keep away from rotating drive spindle and abras-
ives. Rotation may continue for several seconds
after the throttle has been released. Do not lay the
tool down until rotation has stopped
►
Observe that stored compressed air in the hose
may cause an accidental start
►
Release control device if the energy supply should
fail
Maintenance
Rust protection and internal cleaning
Water in the compressed air, dust and wear particles
cause rust and sticking of vanes, valves etc.
This can be solved by lubricating with oil (a few
drops), running the machine for 5-10 seconds and
wiping off excess oil with a cloth.
Do this before
longer standstills.
Lubrication
The front motor ball bearing should be lubricated
with grease in conjuction with the regular overhaul
of the machine.
For flexible spindle extension
– When fitting the
extended spindle – apply 0.5 cm
3
of grease type
“Lubricating Engineers LE3752” (or EP grease) at
the bottom of the hole in the collet holder.
Lubricating guide
Use lubricants of good quality. The oils and greases
listed in the lubrication table are examples of lubric-
ants that can be recommended.

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 fre-
quently to prevent clogging and decreased capacity.

Ergonomic guidelines
1
) Take frequent breaks and change work positions
frequently.
2
) Adapt the workstation area to your needs and the
work task.
• Adjust for convenient reach range by determin-
ing where parts or tools should be located to
avoid static motion.
• Use workstation equipment such as tables and
chairs appropriate for the work task.
3
) Avoid work positions above shoulder level or with
static holding during assembly operations.
• When working above shoulder level, reduce
the load on the static muscles 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, particu-
larly for operations requiring a degree of force.
4
) Adjust for convenient field of vision by minimiz-
ing movement of the eyes and head during the
work task.
5
) Use the appropriate lighting for the work task.
6
) Select the appropriate tool for the work task.
