The power tool can be turned off by releasing the lever
side switch. If the switch is secured, you can press the
rear end of the lever side switch and then release it.
3. Spindle self-locking button
The spindle self-locking button is only used for
replacement of abrasive tools. Do not press the Lock
button when the machine is in operation.
4. Installation of grinding disc (see Fig. C)
Mount the inner flange on the spindle and fix it on the
two shoulders of the spindle. Place the grinding disc
on the inner flange and screw the outer flange onto
the spindle. Press the spindle self-locking button while
turning the grinding disc at the same time until the
spindle is locked tightly; then tighten the outer flange
with the accompanying wrench to fasten the grinding
disc (see Figure C). Insert two bumps of the wrench
into the outer flange holes to tighten the outer flange.
Turn the grinding disc to check whether it is locked.
Run for 30 seconds without load and check whether
there is large vibration or falling off of the grinding disc.
To disassemble the grinding disc, please reverse the
steps above.
5. Adjust the clamping surface of outer
flange(see Fig. D1,D2)
It is needed to adjust the clamping surface of outer
flange to fit the different thicknesses of the abrasive
disc and the blade. If a thinner blade or a diamond
blade is used, the protruding side of the outer flange
should be placed outward (see Figure D2). If a thicker
abrasive disc is used, the protruding side of the outer
flange should be placed towards the abrasive disc (see
Figure D1). Make sure the grinding disc/blade is fixed.
6. Shield of abrasive disc
Put the shield behind the slot of the spindle collar and
screw it to the desired operation position Tighten the
shield with screws. The grinding disc should be able to
rotate freely within the shield.
The operator should have the closed side of
the shield face himself/herself.
PRECAUTIONS
If the machine is severely hot, make your machine run
for 2~3 minutes without load to cool the motor.
Do not start the machine when the grinding disc or
other operational accessories are in contact with the
workpiece.
Please start working after the machine has reached the
maximum speed.
Do not improve the efficiency by increasing the friction
between the grinding disc and the workpiece, otherwise
it will reduce the speed of the grinding disc, which will
lead to longer working hours
When grinding, always keep the angle between the
grinding disc and the working surface at 15-30 degree.
Larger angles will cause uneven working surfaces and
affect the surface quality. Please keep the angle grinder
move back and forth in a crossed manner.
Make sure the workpiece is well clamped without
movement.
MAINTENANCE
Remove the plug from the socket before
carrying out any adjustment, servicing or
maintenance.
There are no user serviceable parts in your power
tool. Never use water or chemical cleaners to clean
your power tool. Wipe clean with a dry cloth. Always
store your power tool in a dry place. Keep the motor
ventilation slots clean. Keep all working controls free
of dust. Occasionally you may see sparks through the
ventilation slots. This is normal and will not damage
your power tool.
If the supply cord is damaged, it must be replaced
by the manufacturer, its service agent or similarly
qualified persons in order to avoid a hazard.
ENVIRONMENTAL
PROTECTION
Waste electrical products should not be disposed
of with household waste. Please recycle where
facilities exist. Check with your local authorities or
