f) Use extra caution when making a "pocket cut"
into existing walls or other blind areas. The pro-
truding wheel may cut gas or water pipes, electrical
wiring or objects that can cause kickback.
Additional Safety Warnings:
17. When using depressed center grinding wheels,
be sure to use only fiberglass-reinforced wheels.
18. Be careful not to damage the spindle, the flange
(especially the installing surface) or the lock nut.
Damage to these parts could result in wheel
breakage.
19. Make sure the wheel is not contacting the work-
piece before the switch is turned on.
20. Before using the tool on an actual workpiece, let
it run for a while. Watch for vibration or wobbling
that could indicate poor installation or a poorly
balanced wheel.
21. Use the specified surface of the wheel to per-
form the grinding.
22. Watch out for flying sparks. Hold the tool so that
sparks fly away from you and other persons or
flammable materials.
23. Do not leave the tool running. Operate the tool
only when hand-held.
24. Do not touch the workpiece immediately after
operation; it may be extremely hot and could
burn your skin.
25. Always be sure that the tool is switched off and
unplugged or that the battery cartridge is
removed before carrying out any work on the
tool.
26. Observe the instructions of the manufacturer for
correct mounting and use of wheels. Handle and
store wheels with care.
27. Do not use separate reducing bushings or adap-
tors to adapt large hole abrasive wheels.
28. Use only flanges specified for this tool.
29. 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.
30. Check that the workpiece is properly supported.
31. Pay attention that the wheel continues to rotate
after the tool is switched off.
32. 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.
33. Do not use the tool on any materials containing
asbestos.
34. Do not use water or grinding lubricant.
35. 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.
36. When use cut-off wheel, always work with the
dust collecting wheel guard required by domes-
tic regulation.
37. Cutting discs must not be subjected to any lat-
eral pressure.
SAVE THESE INSTRUCTIONS.
WARNING:
DO NOT let comfort or familiarity with product
(gained from repeated use) replace strict adherence
to safety rules for the subject product. MISUSE or
failure to follow the safety rules stated in this instruc-
tion manual may cause serious personal injury.

FUNCTIONAL DESCRIPTION

CAUTION:
• Always be sure that the tool is switched off and
unplugged before adjusting or checking function on the
tool.
Adjusting the depth of cut (Fig. 1)
Loosen the wing bolt on the depth guide and move the
base up or down. At the desired depth of cut, secure the
base by tightening the wing bolt.
Only in case you adjust the cutting depth to the maximum
one, always be sure to do the depth adjustment after
adjustment of the wheel guard.
Securing wheel guard (Fig. 2)
CAUTION:
• The wheel guard must be adjusted on the tool so that
the closed side of the guard always points toward the
operator.
The wheel guard can be adjusted about 80 degrees, after
you loosen the clamping nut. Adjust to the desired angle,
then secure the clamping nut.
Switch action (Fig. 3)
CAUTION:
• Before plugging in the tool, always check to see that
the switch trigger actuates properly and returns to the
"OFF" position when released.
For tool with the lock-on switch
To start the tool, simply pull the switch trigger (A direc-
tion). Release the switch trigger to stop.
For continuous operation, pull the switch trigger (A direc-
tion) and then push in the lock lever (B direction).
To stop the tool from the locked position, pull the switch
trigger (A direction) fully, then release it.
For tool with the lock-off switch
To prevent the switch trigger from accidentally pulled, a
lock lever is provided.
To start the tool, push in the lock lever (B direction) and
then pull the switch trigger (A direction). Release the
switch trigger to stop.
For tool with the lock on and lock-off switch
To prevent the switch trigger from accidentally pulled, a
lock lever is provided.
To start the tool, push in the lock lever (B direction) and
then pull the switch trigger (A direction). Release the
switch trigger to stop.
For continuous operation, push in the lock lever, (B direc-
tion) pull the switch trigger (A direction) and then push
the lock lever (B direction) further in.
To stop the tool from the locked position, pull the switch
trigger (A direction) fully, then release it.
