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.
Mounting and adjustment of eye shield bracket
and eye shield
Fig. B
The eye shield bracket and eye shield
should only ever be assembled/adjusted
with the grinding wheel stationary, and
the machine disconnected from the
power supply.
• Mount the eyeshield bracket together with the
eye shield itself, by means of the screw (A).
• Adjust the height of the eyeshield bracket
of the eyeshield by loosening a bit screw .
The free space between the stone and the
eyeshield bracket of the eyeshield will amount
to 1 - 1,5 mm.
• Fasten well screw (A).
• Adjust the eyeshield in such a way that your
face will be protected, at the utmost.
• Use always safety glasses.
Adjusting tool rest
Fig. B
The tool rest should only be adjusted when
the grinding wheel is completely statio-
nary, and the machine is disconnected
from the power supply (the wall socket).
Secure the tool rest, allowing a maximum
clearance (C) between the tool rest and the
grinding stone of 1 -1.5 mm.
Replacing the grinding stone
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 guards, using the above tools.
When replacing the stones, remember the
right-hand spindle is fitted with right-hand
thread, the left-hand spindle with left-hand
thread.
• Loosen the nut by means of the spanner.
Remove the stone.
• Clean the flanges. Replace one flange, with
the concave side facing the grinding stone.
Slide the new grinding stone on to the spindle.
Replace the se cond flange on the spindle, with
the concave side facing the grinding stone.
Tighten the nut securely, but not too tightly!
Replace the guards and adjust the tool rest.
Let the motor run for a few seconds before you
start to grind.
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.
Grinding
The grinding machine comes with one grinding
disc for dry grinding and one for wet grinding.
In principle, the dry-grinding disc is suited for
corase grinding and the wet-grinding disc for fine
grinding where it suffices to press the workpiece
lightly against the grinding stone. This grinding
machine has been especially designed for treating
and grinding tools with cutting edges such as
knives, scissors, chisels, etc. For best results, fill
the water container with tap water.
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
