OPERATING INSTRUCTIONS
NOTE: Before using the tool, read the
instruction book carefully.
1. ON/OFF SWITCH
Slide the switch forward to start your tool and lock
your tool for continuous working. To switch off your
tool, depress the rear of the switch (See A).
2. HAND GRIP AREAS
Always hold your angle grinder firmly with both
hands when operating (See B).
3. ADJUSTABLE FRONT HANDLE
You have the option of two working positions to
provide the safest and most comfortable control of
your angle grinder (See C). The handle is screwed
clockwise into either hole on the sides of the gear
case.
4. SPINDLE LOCK BUTTON
Must only be used when changing a disc. Never press
when the disc is rotating!
5. DISC FITTING
The inner flange (6) is located over the spindle (7)
and on the spindle flat. Locate the disc onto the
inner flange and then the outer flange (5) is screwed
onto the spindle (See E). Press the spindle lock
button (4) and rotate the spindle until it locks, then
firmly tighten the outer flange using your special
spanner to clamp the disc (See D). The pins on your
special spanner locate in the holes on the outer
flange. Check the disc rotates freely and is securely
clamped. Make a no load test run for 30 seconds to
check disc vibration and disc run out. To remove a
disc, reverse these instructions.
6. ADJUSTABLE OUTER FLANGE CLAMPING
The outer flange (5) should be adjusted to suit
different disc thickness. For thinner cutting or
diamond discs the raised part of the outer flange is
fitted facing away from the disc (See F.1). For thicker
grinding discs the raised part of the outer flange is
fitted facing the disc to provide improved support
for the disc hole (See F.2). Always ensure your disc is
securely clamped.
7. GUARD ADJUSTMENT
To move the guard you must release the guard lock
bolt (8) using the other end of the special spanner
(See G). The guard can then be rotated to provide
maximum protection against sparks and debris.
Finally, tighten the guard bolt (8).
8. REMOVING THE GUARD
Only to be removed for use with sanding, flap disc
and wire cup brush accessories only. Never remove
your guard for any other working conditions. Remove
the disc, both flanges, guard bolt, screws (9) x 3 and
guard. Keep all parts in a safe place.
9. FITTING SANDING ACCESSORIES OR WIRE CUP BRUSH
Check the accessory specification for rated speed,
spindle thread and other dimensions are correct for
your angle grinder. Follow the fitting instructions
with your new accessory.
WORKING HINTS FOR YOUR ANGLE
GRINDER
a. If your power tool becomes too hot, run no load for
2-3 minutes to cool the motor.
b. Never start your angle grinder with the disc/ac-
cessory in contact with the workpiece.
c. Always start at no load to achieve maximum speed
then start working.
d. Do not force the disc to work faster, reducing the
Disc’s moving speed means longer working time.
e. Always work with a 10-20 angle between disc and
workpiece when grinding. Larger angles will cut
ridges into the workpiece and affect the surface
finish. Move the angle grinder across and back and
forth over the workpiece.
f. When using a cutting disc never change the
cutting angle otherwise you will stall the disc
and angle grinder motor or break the disc. When
