OrIgINaL INstructIONs

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.

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.

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.
