To fasten the wheel guard(9), close the clamping
lever.
The closed side of the wheel guard(9) must
always point to the operator.
NOTE: with the clamping lever open the clamp
adjusting nut can be adjusted to ensure the
guard(9) is securely clamped after the clamping
lever is finally closed.
Wheel Guard for Grinding(not supplied)
The wheel guard for grinding (14) is mounted
in the same manner as the wheel guard for
cutting(9)
7. uSING ThE TuRNING hANDLE (See F)
To best suit the
different working
positions, your
angle grinder is
equipped with a
turning handle.
F
Press the rear of
the locking button on the turning handle and you
can rotate the handle 900 to left or right. Then
release the locking button. A click will be heard,
when the handle is then fully locked in place.
WARNING! Make sure the handle in the
locked position before start the angle
grinder.
Rotating the handle is permitted only in the
switched off condition.
8. CuTTING
WARNING! For cutting metal, always work
with the wheel guard for 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-grinding
motion. Therefore, never move the machine in
the other direction! Otherwise, the danger exists
of it being pushed uncontrolled out of the cut.
9. TO uSE ThE GRINDER (See G)
ATTENTION: Do not switch the grinder
on whilst
the disc is in
contact with the
workpiece. Allow
the disc to reach
G
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 15 -30
0
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.
10. REPLACING CARbON bRuShES (not
supplied) (See h)
Disconnect the
plug from the
power supply.
Completely
unscrew the
screws on the
h
carbon brush
cover. Loosen the fixing screw on the brush
cover and remove it. Check the length of the
brush and replace if under 7mm. When brushes
need replacement always renew both brushes,
even if one is more than 7mm. Set the brush
cover into the body. Secure the brush cover
screw. Replace the cover and screw. Check the
tool is working before use, allow it run for a few
minutes to enable the brushes to settle.
11. SOFT START
Internal electronic components allow the motor
speed to increase slowly, which reduces the
"twisting" effect on your wrists due to the high
power motor.
wORKING HINTS FOR
YOUR 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, wheels/
when grinding.
