Work area
• Keep work area clean and well lit. Cluttered and dark
areas invite accidents.
• Do not operate power tools in explosive
atmospheres, such as in the presence of flammable
liquids, gases, or dust.
which may ignite the dust or fumes.
• Keep children and bystanders away while operating a
power tool.
Electrical safety
• Power tool plugs must match the outlet. Never modify
the plug in any way. Do not use any adapter plugs with
earthed (grounded) power tools. Unmodified plugs and
matching outlets will reduce risk of electric shock.
• Avoid body contact with earthed or grounded
surfaces such as pipes, radiators, ranges and refrig
erators. There is an increased risk of electric shock if
your body is earthed or grounded.
• Do not expose power tools to rain or wet
conditions. Water entering a power tool will increase
the risk of electric shock.
• Do not abuse the cord. Never use the cord for
carrying, pulling or unplugging the power tool. Keep
cord away from heat, oil, sharp edges or moving parts.
Damaged or entangled cords increase the risk of
electric shock.
• When operating a power tool outdoors, use an
outdoor extension cord suitable for outdoor use.
Use of a cord suitable for outdoor use reduces the risk
of electric shock.

Additional safety rules for angle grinders
• Fully unwind cable drum extensions to avoid potential
overheating.
• When an extension cable is required, you must ensure
that it has the right ampere rating for your power tool and
is in safe electrical condition.
• Always switch off before you put the angle grinder down.
• Do not let anyone under 18 years operate this tool.
• Rags, cloths, cord, string and the like should never be
left around the work area.
• If you are interrupted when operating the tool, complete
the process and switch off before looking up.
• Periodically check that all nuts, bolts and other fixings
are properly tightened.
• Check the disc before mounting it into the angle
grinder. Check by striking it with a wooden handle whilst
balancing the disc on your finger. Listen for the ring and
do not use if dull, as the disc may be cracked.
• When the disc is installed, run it for at least one minute
to ensure that it does not have a fault. It is always
advisable to stay out of the line of the disc when testing
or when using the tool.
• Do not use a disc marked with a lower RPM than that of
the no load speed shown on the rating plate.
• Use discs only of the prescribed diameter.
• Do not use the angle grinder for buffing or polishing
under any circumstances.
• Never try to operate the angle grinder without the guard
in place.
• Do not secure the angle grinder in a vice or work bench
and use it as a static grinder. It can lead to serious injury.
• Never apply excessive pressure to the disc. It might
shatter causing personal injury.
• Ensure the work piece to be ground or cut, is held tight
in the vice or other clamping system.

• Always use the side handle and ensure a good grip on
the grinder housing with one hand and the handle with
the other hand before proceeding with any work.
• Make sure that the disc is not in contact with the work
when you start the grinder.
• Be careful not to damage the spindle or either of the disc
flanges. Damage to these parts could result in disc breakage.
• Do not press the spindle lock button whilst the spindle is
turning.
• Only use good quality grinding and cut off discs. Cheap
poor quality discs tend to glaze up which loads the
motor and can damage it. Use discs for their designated
purpose only. For instance, do not use cutting discs for
grinding or metal wheels on masonry.
• Watch out for flying sparks. Hold the tool at an angle of
approximately 15º to 30º to the work piece surface.
• Let the disc do the grinding or cutting at a reasonable
feed, as overloading will occur if too much pressure is
applied and the disc slows resulting in inefficient cutting
and possible damage to the motor.
• When using the grinder, use safety equipment including
safety goggles or shield, ear protection, dust mask and
protective clothing including safety gloves.
ALWAYS WEAR EYE PROTECTION
Wear goggles
Wear hearing protection
Wear a breathing mask

WARNING.
the power point.
NOTE. Grinding operations normally require the angle
grinder to be held with the grinding disc parallel to the
plane of the workpiece whilst cutting operations normally
require the angle grinder to be held with the cutting
disc at right angles to the workpiece. Take the time
to find the best combination of front handle and main
handle positions to suit the task on hand. It can make a
considerable difference to the levels of convenience and
safety of operation.
1. Open the quick release guard lever (11).
2. Position the lug on the inside of the central guard ring in
the vertical slot in the spindle cover and press the guard
onto the spindle cover.
3. Twist the guard to the appropriate position for either
grinding or cutting.
4. Lock the guard in position with the quick release
guard lever.

Operation
This angle grinder can be used for grinding and cutting
steel, stone or ceramic workpieces such as pipe, box
section, rectangular, angle iron
steel bar, house bricks and tiles.
Do not attempt to grind wood or
a soft metal such as lead. The
material will quickly “fill” the disc
and render it useless.
Before starting the grinder first
ensure that the disc, disc guard
and tool are in good condition.
Position the guard (3) as described in the disc guard section
so that it will deflect hot sparks away from the operator.
Switching on and off
1. Plug the power cord into the power point.
2. Start the tool by pushing
the on/off trigger switch (5)
forward up and over the
latching ramp to lock the
switch on.
3. Hold the grinder firmly while
it is switched on and only
apply gentle pressure to the
workpiece. Little more than the
weight of the tool should be
applied to give the best and
most efficient material removal.
Forcing and excessive
pressure can cause dangerous
disc fracture or damage to
the tool. Hold the grinder at
approximately 15° to 30º to the
work and move slowly.
4. Once the grinding or cutting is finished, push the back
section of the on/off switch (5) to stop the grinder.

section or a depressed inner section, proceed as follows.
6. For discs with a flat inner
section, screw on the outer
flange (8) with the protruding
spigot section facing away
from the disc.
7. For discs with a depressed
inner section, screw on
the outer flange with the
protruding spigot section
facing the disc so that it
locates in the hole in the disc.
8. Hand tighten the outer flange
until the disc is secure.
9. Press the spindle lock button
and tighten the flange with the
wrench.
10. Turn the new disc by hand,
ensuring that it is tightly
secured and that it rotates fully

11. Run the angle grinder under
no load for at least one
minute to ensure the new
disc is in good condition.
Make sure you are wearing
all the safety gear and that
you face the grinder away from you.
CAUTION. Do not use excessive force to clamp the disc.
It could crack it and cause failure during use.
WARNING. Do not immerse the disc into any type of
lubricant including water. This angle grinder is designed as
a dry grinder/cutter. Failure to observe this warning could
result in a fatal shock.
