Using extension cables
Only use an approved extension cable suitable
for the power input of the machine. The minimum
conductor size is 1.5 mm2. When using a cable
reel always unwind the reel completely.
3. INSTALLATION
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. B
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 (4) with attached
spark guard to the grinding wheel cover, using
the screw provided (A).
• Set the spark guard bracket at the correct
height. The clearance (B) between the wheel and
the spark guard bracket should be 1 to 1.5 mm.
• Next tighten the screw (A) firmly.
• Position the spark guard to give maximum
protection when working.
• Always wear safety glasses.
Fitting and adjusting tool rest
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 as shown in Fig. C.
• Fix it as tightly as possible in position, with
a maximum clearance (C) of 1 to 1.5 mm
between the tool rest and the grinding wheel.
Replacing the grinding wheel
Fig. C
Required tools:
• 19 mm spanner
• 8 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 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
grinding wheel. Slide the new wheel onto the
spindle. 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.
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 workpiece
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
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
creating 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
