Do not reduce the speed of running down cutting discs by
applying sideward pressure.
The direction in which the cutting is performed is important.
The machine must always work in an up-grinding motion.
Therefore, never move the machine in the other direction!
Otherwise, the danger exists of it being pushed uncontrolled
out of the cut.
8. CHANGING CARBON BRUSHES
(SEE FIG. F)
WARNING! Before replacing the
brushes, remove the plug at the mains.
Remove the screw securing the motor back cover. Remove
the back cover.
Next raise the end of the spring and slide the brush out from
the brush holder, easing the connector from its termainal.
Check the length of the brush and replace if under 6mm.
Worm brushes should be replaced in the same holder and
position as removed.
Insert the exsiting brush or new brush, secure the connector,
reposition the spring and then check the other brush. When
brushes need replacement always renew both brushes,
even if one is still more than 6mm long.
Check that the tool is working. Before use, allow it to run for
a few minutes to enable the brushes to settle.
9. OVERLOAD
Overloading will cause damage to the motor of your angle
grinder. This can happen if your angle grinder is subjected to
heavy use for prolonged periods of time.
Do not in any circumstances, attempt to exert too much
pressure on your angle grinder to speed up your work.
If your angle grinder becomes too hot, run you angle grinder
under no load for 2-3 minutes until it has cooled to normal
operation temperature.
WORKING HINTS FOR
YOUR ANGLE GRINDER
1. Your angle grinder is useful for both cutting through
metals, i.e. for removing screw heads, and also for
cleaning / preparing surfaces, i.e. before and after
welding operations.
2. Different types of wheel/cutter will allow the grinder
to meet various needs. Typically, grinding wheels and
cutting discs are available for mild steel, stainless
steel, stone and brick. Diamond impregnated discs are
available for very hard materials.
3. If the grinder is used on soft metals such as aluminum
the wheel will soon clog and will have to be changed.
4. At all times, let the grinder do the work, do not force it
or apply excessive pressure to the wheel/disc.
5. If cutting a slot ensure that the cutter is kept aligned
with the slot, twisting the cutter may cause the disc
to shatter. If cutting through thin sheet, only allow the
cutter to just project through the material, excessive
penetration can increase the chance of causing
damage.
6. If cutting stone or brick, it is advisable to use a dust
extractor.
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.
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 will not operate check the power at the
main plug.
2. If your grinder wheel wobbles or vibrates, check that
outer flange is tight, check that the wheel is correctly
located on the flange plate.
3. 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.
4. If working on aluminum or a similar soft alloy, the wheel
will soon become clogged and will not grind effectively.
