excessive depth of cut. Overstressing the wheel
increases the loading and susceptibility to twisting or
binding of the wheel in the cut and the possibility of
kickback or wheel breakage.
b) Do not position your body in line with and
behind the rotating wheel. When the wheel, at the
point of operation, is moving away from your body, the
possible kickback may propel the spinning wheel and
the power tool directly at you.
c) When wheel is binding or when interrupting a
cut for any reason, switch off the power tool and
hold the power tool motionless until the wheel
comes to a complete stop. Never attempt to
remove the cut-off wheel from the cut while the
wheel is in motion otherwise kickback may occur.
Investigate and take corrective action to eliminate the
cause of wheel binding.
d) Do not restart the cutting operation in the
workpiece. Let the wheel reach full speed and
carefully re-enter the cut. The wheel may bind, walk
up or kickback if the power tool is restarted in the
workpiece.
e) Support panels or any oversized workpiece to
minimize the risk of wheel pinching and kickback.
Large workpieces tend to sag under their own weight.
Supports must be placed under the workpiece near
the line of cut and near the edge of the workpiece on
both sides of the wheel.
f) Use extra caution when making a "pocket cut"
into existing walls or other blind areas. The
protruding wheel may cut gas or water pipes, electrical
wiring or objects that can cause kickback.
Additional Safety Warnings:
17. When using depressed centre grinding wheels, be
sure to use only fiberglass-reinforced wheels.
18. NEVER USE Stone Cup type wheels with this
grinder. This grinder is not designed for these types of
wheels and the use of such a product may result in
serious personal injury.
19. 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.
20. Make sure the wheel is not contacting the
workpiece before the switch is turned on.
21. 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.
22. Use the specified surface of the wheel to perform
the grinding.
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. Observe the instructions of the manufacturer for
correct mounting and use of wheels. Handle and
store wheels with care.
26. Do not use separate reducing bushings or
adaptors to adapt large hole abrasive wheels.
27. Use only flanges specified for this tool.
28. 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.
29. Check that the workpiece is properly supported.
30. Pay attention that the wheel continues to rotate
after the tool is switched off.
31. 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.
32. Do not use the tool on any materials containing
asbestos.
33. When use cut-off wheel, always work with the dust
collecting wheel guard required by domestic
regulation.
34. Cutting discs must not be subjected to any lateral
pressure.
35. Do not use cloth work gloves during operation.
Fibers from cloth gloves may enter the tool, which
causes tool breakage.
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 instruction
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.
Shaft lock
CAUTION:
• Never actuate the shaft lock when the spindle is
moving. The tool may be damaged. (Fig. 1)
Press the shaft lock to prevent spindle rotation when
installing or removing accessories.
Switch action
CAUTION:
• Before plugging in the tool, always check to see that
the switch trigger actuates properly and returns to the
"OFF" position when released. (Fig. 2)
For tool with the lock-on switch
To start the tool, simply pull the switch trigger (in the B
direction). Release the switch trigger to stop. For
continuous operation, pull the switch trigger (in the B
direction) and then push in the lock lever (in the A
direction). To stop the tool from the locked position, pull
the switch trigger fully (in the B direction), 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 (in the A direction)
and then pull the switch trigger (in the B direction).
Release the switch trigger to stop.
