Assembling the hand grip
Fig. 1
The hand grip is suitable for either left or right-
handed use.
• Turn the hand grip (3) to the notch on the
right side of the machine for left-handed
use.
• Turn the hand grip (3) to the notch on the
left side of the machine for right-handed
use.
• Turn the hand grip to the notch on the top
of the machine to use it vertically.
Disassembly
• Remove the flange nut and the grinding
disc with lower flange from the spindle.
• Unscrew the 4 screws (with washers) en
remove the fixing-ring.
• Remove the guard from the machine.
Mounting a grinding disc
Fig. 2
Use grinding discs of the correct dimension.
Use fibre reinforced grinding discs only.
The grinding disc must not touch the edge of
the guard.
• Press the spindle lock (6) and turn the
spindle (9) until it engages in the lock.
Keep the spindle lock pressed during this
procedure.
• Remove the flange nut (12) from the
spindle using the spanner (11).
• Position the grinding disc (7) on the flange
(5).
• Place the flange nut on the spindle an
tighten it using the spanner.
• Release the spindle lock and check that
the spindle is unlocked by rotating it.
Mounting grinding discs and roughing discs
Fig. 4 and 5 show how to mount the flange (10)
when using thick (4 – 8 mm) and thin
(2,5 – 4 mm) discs.
The following grinding discs can be used with
this grinder.
• For deburring: grooved, fibreglass
reinforced type 27. Dimensions Ø 125 x
6.0 x 22.2 mm.
• For slitting/ cutting: grooved, fibreglass
reinforced, type 41 and type 42.
Dimensions Ø 125 x 3.0 x 22.2 mm.
If you use normal grinding discs they
shouldalwaysbefibreglassreinforced.
4. USE
Alwaysfollowthesafetyinstructions
and keep to the applicable regulations.
Hold the machine away from the workpiece
when turning it on and off because the grinding
disc could damage the workpiece.
• Clamp the workpiece firmly or use another
method to ensure that it cannot move while
working.
• Check the discs regularly. Worn grinding
discs have a negative effect on the
machine’s efficiency. Change to a new
grinding disc in good time.
• Always first turn the machine off after use
before removing the plug from the socket.
Deburring
Fig. 5
An angle of inclination of 30º to 40º will give the
best results when deburring. Move the machine
back and forth using light pressure. This will
prevent the workpiece from discolouring or
becoming too hot and will avoid making groves.
Never use abrasive cutting discs for
deburringwork!
Cutting
Fig. 6
Maintain firm contact with the workpiece
to prevent vibration and do not tilt or apply
pressure and when cutting. Use moderate
pressure when working, appropriate to the
material that is being worked on. Do not slow
down grinding discs by applying sideways
counter pressure. The direction in which you
want to cut is important. The machine must
always work against the direction of the cut; so
never move the machine in the other direction!
There is the risk that the machine will catch in
the cut causing kickback and that you will lose
control.
