is mounted in the same manner as the wheel
guard for grinding(5).
3. FITTING THE DISCS (See Fig. C1,C2)
Put the inner flange onto the tool spindle.
Ensure it is located on the two flats of
spindle.
Place the disc on the tool spindle and inner
flange. Ensure it is correctly located. Fit the
threaded outer flange making sure it is facing
in the correct direction for the type of disc
fitted. For grinding discs, the flange is fitted
with the raised portion facing towards the
disc. For cutting discs, the flange is fitted
with the raised portion facing away from the
disc (See Fig. C1).
Press in the spindle lock button and rotate the
spindle by hand until it is locked. Keeping the
lock button pressed in, tighten the outer flange
with the spanner provided. (See Fig. C2).
4. SAFETy ON/OFF SWITCH (See Fig. D)
Your switch is locked off to prevent
accidental starting. With your hand on the
on/off switch (a) use your finger to push
lever (b) forward and then depress on/off
switch (a). Then release lever (b). Your tool
is now on. To switch off just release on/off
switch.
5. VARIABLE SPEED CONTROL (See Fig.
E)(Wx722 Wx722.1)
Adjust the thumb-wheel to increase or
decrease the speed (See Fig. E) according
to the material, material thickness and disc/
accessory specification to be used (also
possible during no load operation). See Table
1 for general guidance on speed selection.
Avoid prolonged use at very low speeds
as this may damage your angle grinder's
motor. The constant speed control electronic
circuit inside your angle grinder maintains a
nearly constant speed even when your angle
grinder is under load.

Must only be used when changing a disc.
Never press when the disc is rotating!
7. TO USE THE GRINDER
contact with the workpiece. Allow the
disc to reach full speed before starting
to grind.
Hold your angle grinder with one hand on the
main handle and other hand firmly around
the auxiliary handle.
Always position the guard so that as much
of the exposed disc as possible is pointing
away from you.
Be prepared for a stream of sparks when the
disc touches the metal.
For best tool control, material removal
and minimum overloading, maintain an
angle between the disc and work surface of
approximately 150 -300 when grinding.
Use caution when working into corners as
contact with the intersecting surface may
cause the grinder to jump or twist.
When grinding is complete allow the
workpiece to cool. Do not touch the hot
surface.
8. CUTTING
When cutting, do not press, tilt or oscillate
the machine. Work with moderate feed,
adapted to the material being cut.
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-
Speed setting
grinding motion. Therefore, never move the
machine in the other direction! Otherwise,

the danger exists of it being pushed
uncontrolled out of the cut.
ATTENTION: Do not switch the
grinder on whilst the disc is in
WARNING! For cutting metal, always
work with the wheel guard for cutting.
