WHEEL GUARD FOR CUTTING
WARNING! For cutting metal,always
work with the wheel guard for
cutting(14). The wheel guard for cutting (14)
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.
SOFT START MOTOR(WX722.1)
Internal electronic components allow the
motor speed to increase slowly, which
reduces the"twisting"effect on your wrists
due to the high power motor.

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
Angle grinder
motor. The constant speed control electronic
circuit inside your angle grinder maintains a
nearly constant speed even when your angle
grinder is under load.

6. SPINDLE LOCK BUTTON

Must only be used when changing a disc.
Never press when the disc is rotating!
7. TO USE THE GRINDER
ATTENTION: Do not switch the
grinder on whilst the disc is in
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
WARNING! For cutting metal, always
work with the wheel guard for cutting.
When cutting, do not press, tilt or oscillate
