WORKING HINTS FOR YOUR ANGLE
GRINDER
1. Always start at no load to achieve maximum speed
then start working.
2. Do not force the disc to work faster, reducing the Disc's
moving speed means longer working time.
3. Always work with a 15-30 angle between disc and
workpiece when grinding. Larger angles will cut ridges
into the workpiece and affect the surface finish. Move
the angle grinder across and back and forth over the
workpiece.
4. When using a cutting disc never change the cutting
angle otherwise you will stall the disc and angle
grinder motor or break the disc. When cutting, only cut
in the opposite direction to the disc rotation. If you cut
in the same direction as the disc rotation the disc may

push itself out of the cut slot.
5. When cutting very hard material best results can be
achieved with a abrasive cutting disc.
6. When using a abrasive cutting disc it will become very
hot. If this happens you will see a full ring of sparks
around the rotating disc. Stop cutting and allow to cool
at no load speed for 2-3 minutes.
7. Always ensure the workpiece is firmly held or clamped
to prevent movement.
MAINTENANCE
Remove the battery 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. Store the
accessories in a dry place.
TROUBLESHOOTING
Although your new angle grinder is really very simple to
operate, if you do experience problems, please check the
following:
1. If your grinder wheel wobbles or vibrates, check that
outer flange is tight; check that the wheel is correctly
located on the flange plate.
2. If there is any evidence that the wheel is damaged
do not use as the damaged wheel may disintegrate,
remove it and replace with a new wheel. Dispose of old
wheels sensibly.
3. If working on aluminum or a similar soft alloy, the
wheel will soon become clogged and will not grind
effectively.
4. When overloaded, the motor comes to a stop. Relieve
the load on the machine immediately and allow cooling
for approx. 30 seconds at the highest no-load speed.
5. When using as intended for the power tool cannot be
subject to overload. When the load is too high or the
allowable battery temperature of 75 °C is exceeded,
the electronic control switches off the power tool until
the temperature is in the optimum temperature range
again.
6. If machine is blocked, please turn it off and turn it on
again after 1~2 seconds.
