ADDITIONAL SAFETY RULES
ENB031-5
1.
Always use eye and ear protection. Other per-
sonal protective equipment such as dust mask,
gloves, helmet and apron should be worn when
necessary. If in doubt, wear the protective equip-
ment.
2.
Always be sure that the tool is switched off and
unplugged before carrying out any work on the
tool.
3.
Keep guards in place.
4.
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. When using depressed
centre wheels, be sure to use only fiberglass-
reinforced wheels.
5.
Check the wheel carefully for cracks or damage
before operation. Replace cracked or damaged
wheel immediately.
6.
Observe the instructions of the manufacturer for
correct mounting and use of wheels. Handle and
store wheels with care.
7.
Do not use separate reducing bushings or adap-
tors to adapt large hole abrasive wheels.
8.
Use only flanges specified for this tool.
9.
Do not damage the spindle, the flange (espe-
cially the installing surface) or the lock nut. Dam-
age to these parts could result in wheel
breakage.
10. For tools intended to be fitted with threaded hole
wheel, ensure that the thread in the wheel is long
enough to accept the spindle length.
11. 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.
12. Check that the workpiece is properly supported.
13. Hold the tool firmly.
14. Keep hands away from rotating parts.
15. Make sure the wheel is not contacting the work-
piece before the switch is turned on.
16. Use the specified surface of the wheel to per-
form the grinding.
17. Do not use cutting off wheel for side grinding.
18. Watch out for flying sparks. Hold the tool so that
sparks fly away from you and other persons or
flammable materials.
19. Pay attention that the wheel continues to rotate
after the tool is switched off.
20. Do not touch the workpiece immediately after
operation; it may be extremely hot and could
burn your skin.
21. Position the tool so that the power cord always
stays behind the tool during operation.
22. If working place is extremely hot and humid, or
badly polluted by conductive dust, use a short-
circuit breaker (30 mA) to assure operator safety.
23. Do not use the tool on any materials containing
asbestos.
24. Do not use water or grinding lubricant.
25. Ensure that ventilation openings are kept clear
when working in dusty conditions. If it should
become necessary to clear dust, first disconnect
the tool from the mains supply (use non metallic
objects) and avoid damaging internal parts.
26. When use cut-off wheel, always work with the
dust collecting wheel guard required by domes-
tic regulation.
27. Cutting discs must not be subjected to any lat-
eral pressure.
SAVE THESE INSTRUCTIONS.
OPERATING INSTRUCTIONS
Installing wheel guard (Fig.1)
CAUTION:
Always be sure that the tool is switched off and
unplugged before installing or removing the wheel guard.
When using a depressed center wheel or a cut-off wheel,
always use a wheel guard. Mount the wheel guard with
the tab on the wheel guard band aligned with the notch
on the bearing box. Then rotate the wheel guard
180 degrees counterclockwise. Be sure to tighten the
screw securely.
Installing side grip (auxiliary handle) (Fig. 2)
CAUTION:
Always be sure that the tool is switched off and
unplugged before installing or removing the side grip.
Screw the side grip on the tool securely.
The side grip can be installed on either side of the tool,
whichever is convenient.
Installing or removing depressed center wheel
(Fig. 3 & 5)
CAUTION:
Always be sure that the tool is switched off and
unplugged before installing or removing the wheel.
Mount the inner flange onto the spindle. Fit the wheel on
over the inner flange and screw the super nut onto the
spindle. So that the side with the wrench holes faces out-
side.
To tighten the super nut, press the shaft lock firmly so
that the spindle cannot revolve, then use the lock nut
wrench and securely tighten clockwise.
To remove the wheel, follow the installation procedure in
reverse.
