Fitting and adjusting tool rest (Fig. E)
The tool rest should only be adjusted when
the grinding wheel is completely stationary,
and the machine is disconnected from the
power supply (the wall socket).
• Fit the tool rest (8) as shown in Fig. E.
• Fix it as tightly as possible in position, with a
maximum clearance of 1 to 1.5 mm between
the tool rest (8) and the grinding wheel (5).
Replacing the grinding wheel (Fig. F, G & H)
Required tools:
• 17 mm spanner
• Screwdriver
Only ever replace the grinding wheel when
the motor is at a standstill and the power is
completely disconnected.
• Remove the grinding wheel guards (4) using the
tools listed above. The spindle nut on the right-
hand side has a right-handed thread.
The spindle nut on the left-hand side has a
left-handed thread. Keep this in mind when you
are replacing the grinding wheels.
• Loosen the nut using the correct spanner.
Remove the old wheel from the spindle.
• Clean the flanges. Place one flange (A) back on
the spindle, with the hollow side facing the grin-
ding wheel. Slide the new wheel onto the spind-
le. Place the second flange (A) on the spindle,
again with the hollow side facing the grinding
wheel. Now tighten the nut on the spindle. Do
not overtighten! Now refit the grinding wheel
cover, and again adjust the tool rest correctly.
Run the motor briefly, without grinding.
Flexible shaft (Fig. I)
Mount the flexible shaft (12) on the bench grinder.
The ring of the flexible shaft (12) can then be faste-
ned onto the bench grinder.
To mount an accessory in the flexible shaft (Fig. J)
Lock the spindle by putting the pin (13) in the pin
opening. Then loosen the chuck with the chuck
spanner (14) and place the accessory. Keep the pin
(13) in place and tighten the chuck. Make sure to
remove the pin (13) before operating the machine.

Accessories for the Rotary multi tool
Always check that the maximum rpm of the accessory
is suitable for the maximum speed of the Multi tool.
4. OPERATION
Selecting the grinding wheel
Coarse grinding wheels will in general remove the
most material, and fine grinding wheels are used
for finishing. If the surface is uneven, begin by
using a coarse grinding wheel, and grind the work-
piece until it is smooth. Next use a fine grinding
wheel to remove the grooves and scratching left by
the coarse wheel, and finish off the workpiece.
How to grind (Fig. A)
To prevent the grinding surface from blocking up,
avoid holding wood, lead or any other soft material
or metal against the grinding wheel. To avoid crea-
ting grooves, do not press the workpiece too firmly
on the grinding wheel. Use water to regularly cool
the workpiece being ground. Wood chisels and the
like should never be sharpened 'blue'. Take care
not to lose your grip on the object being ground, as
it may suddenly become jammed between the tool
rest and the grinding wheel. This can cause the
stone to shatter, the motor to seize, or the work-
piece to fly off, all of which can cause injury and
damage. Whenever the machine has been in use
for 30 minutes, it should be switched off. Allow the
machine to cool down to room temperature.
Switching the machine on
• Check that the switch (1) is in the "OFF/0"
position before connecting the machine to the
power supply.
• Press the power switch (1) into the " ON/1"
position to start your bench grinder.
• Always keep the power cord out of the way of
the tool's moving parts.
Speed Adjustment (Fig. A)
The required speed can be adjusted by using the
Speed adjustment knob (11). Also during running
the rotational speed can be adjusted.
• To increase the speed, turn the Speed adjust-
ment knob (11) clockwise.
• To decrease the speed, turn the Speed adjust-
ment knob (11) anti-clockwise.
The required speeds depends on the material and
can be determined by practical testing.
