3. ASSEMBLY
The grinder must be firmly bolted to a workbench.
The length of the fixing bolts will depend on the
thickness of the workbench. If the workbench is
made of steel, it is advisable to use a wooden block
or plank between the grinder and the bench, to
insulate it and prevent vibration.
Assembly and adjustment of spark guard bracket
and spark guard (Fig. C & D)
The spark guard bracket and spark guard
should only ever be assembled/adjusted
with the grinding wheel stationary, and the
machine disconnected from the power
supply.
• Fix the spark guard bracket (3) to the grinding
wheel cover, using the screws provided (10).
• Set the spark guard bracket at the correct
height. The clearance between the wheel and
the spark guard bracket should be 1 to 1.5 mm.
• Next tighten the screws (10) firmly.
• Fix the spark guard (2) to the spark guard
bracket (3).
• Position the spark guard to give maximum
protection when working.
• Always wear safety glasses.
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.
8
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
