Additional Safety Rules - Makita 906 Betriebsanleitung

20. Check damaged parts
Before further use of the tool, a guard or other
part that is damaged should be carefully checked
to determine that it will operate properly and per-
form its intended function. Check for alignment of
moving parts, binding of moving parts, breakage
of parts, mounting, and any other conditions that
may affect its operation. A guard or other part
that is damaged should be properly repaired or
replaced by an authorized service center unless
otherwise indicated elsewhere in this instruction
manual. Have defective switches replaced by
and authorized service center. Do not use tool if
switch does not turn it on and off.
21. Warning
The use of any other accessory or attachment
other than recommended in this operating
instruction or the catalog may present a risk of
personal injury.
22. Have your tool repaired by an expert
This electric appliance is in accordance with the
relevant safety rules. Repairing of electric appli-
ances may be carried out only by experts other-
wise it may cause considerable danger for the
user.

ADDITIONAL SAFETY RULES

1. Always wear safety goggles and ear protec-
tors during operation.
2. Use only wheels with correct size and wheels
having a maximum operating speed at least
as high as the highest No Load Speed
marked on the tool's nameplate.
3. Check the wheel carefully for cracks or dam-
age before operation. Replace cracked or
damaged wheel immediately.
4. Observe the instructions of the manufacturer
for correct mounting and use of wheels. Han-
dle and store wheels with care.
5. Before using the tool on an actual workpiece,
test run the tool at the highest no load speed
for at least 30 seconds in a safe position.
Stop immediately if there is any vibration or
wobbling that could indicate poor installation
or a poorly balanced wheel. Check the tool to
determine the cause.
6. Check that the workpiece is properly sup-
ported.
7. Hold tool by insulated gripping surfaces
when performing an operation where the cut-
ting tool may contact hidden wiring or its own
cord. Contact with a "live" wire will make
exposed metal parts of the tool "live" and
shock the operator.
8. Make sure the wheel is not contacting the
workpiece before the switch is turned on.
9. Watch out for flying sparks. Hold the tool so
that sparks fly away from you and other per-
sons or flammable materials.
10. Pay attention that the wheel continues to
rotate after the tool is switched off.
11. Hold the tool firmly.
12. Keep hands away from rotating parts.
13. Do not leave the tool running. Operate the
tool only when hand-held.
14. Do not touch the workpiece immediately after
operation; it may be extremely hot and could
burn your skin.
15. Always be sure you have a firm footing. Be
sure no one is below when using the tool in
high locations.
16. Do not use the tool on any materials contain-
ing asbestos.
17. Do not use water or grinding lubricant.
18. Do not use this tool as cutter.
SAVE THESE INSTRUCTIONS.
OPERATING INSTRUCTIONS
Installing or removing wheel point (Fig. 1 & 2)
Important:
• Always be sure that the tool is switched off and
unplugged before installing or removing the wheel
point.
• Ensure that the wheel point dimensions are com-
patible with the grinder and that the wheel point fits
the spindle.
Loosen the collet nut and insert the wheel point into
ENB044-1
the collet nut. Use the smaller wrench to hold the
spindle and the larger one to tighten the collet nut
securely.
The wheel point should not be mounted more than
10 mm from the collet nut. Exceeding this distance
could cause vibration or a broken shaft.
To remove the wheel point, follow the installation pro-
cedure in reverse.
Switch action (Fig. 3)
To start the tool, move the switch to the "ON" position.
To stop, move the switch to the "OFF" position.
Operation (Fig. 4)
Turn the tool on without the wheel point making any
contact with the workpiece and wait until the wheel
point attains full speed. Then apply the wheel point to
the workpiece gently. To obtain a good finish, move
the tool in the leftward direction slowly.
CAUTION:
• Apply light pressure on the tool. Excessive pres-
sure on the tool will only cause a poor finish and
overloading of the motor.
• The wheel point continues to rotate after the tool is
switched off.
Dressing wheel point (Fig. 5)
When the wheel point becomes "loaded" with various
bits and particles, you should dress the wheel point
with the dressing stone.
