BEFORE USING THE MACHINE:
1. Check the following:
- Make sure that your machine is correct for your
power supply.
- Make sure the socket is earthed;
- Make sure the cable and socket are in good con-
dition, i.e. not frayed or damaged.
2. Do not use long extension cables.
Use only earthed extension cables.
3. A grinding stone is fragile.
The stone is easily damaged when being dropped, hit,
etc. Always grind with the face of the grinding stone,
never the sides. A cracked grinding stone must be
replaced immediately. Due to the high rotational
velocity the stone might disintegrate, causing acci-
dents.
4. Always wear safety glasses when grinding.
5. Never operate the grinding machine without the
guard in place.
6. Make sure the guard and the tool rest are properly
adjusted and secured.
7. The maximum clearance between the tool rest and
the grinding stone must never exceed 1-1.5 mm.
8. Use the stone only for its intended purpose, e.g. for
grinding tools, never for heavy-duty construction
work.
Use only grinding stones that state the following:
- Name of the manufacturer;
- Binding material;
- Dimensions;
- Maximum speed.
9. Never rebore the arbor hole in the grinding stone to
widen the diameter.
10. The maximum admissable rotational velocity of the
grinding stone may not exceed the velocity mentio-
ned on the stone.
11. For safe grinding it is best to bolt the machine to the
bench.
BEFORE YOU OPERATE THE MACHINE:
1. Make sure the switch is “OFF” before you plug in the
machine.
2. Keep the cable away from moving parts.
SWITCH OFF THE MACHINE IMMEDIATELY
IN CASE OF
1. Malfunction in the mains plug, power cable or dama-
ging of cable.
2. Broken switch.
3. Smoke or stench of scorched insulation.
INSTALLATION
Fig. B.
The holder of a cover glass, together with the cover
glasses themselves will always be adjusted/moun-
ted with the grinding stone being out of action and the current
turned out.
The grinding machine has to be secured to the bench by
means of bolts. The length of the bolts depends on the
thickness of the bench. If your bench is made of steel, it is
best to place the machine on a supporting, wooden plate
to separate it from the bench, to avoid vibrations.
MOUNTING AND ADJUSTMENT THE
COVER GLASSES AND HOLDERS
- Mount the holder of the cover glass together with
the cover glass itself, by means of the screw (A).
- Adjust the height of the holder of the cover glass by
loosening a bit screw . The free space between the
stone and the holder of the cover glass will amount
to 1 - 1,5 mm.
- Fasten well screw (A).
- Adjust the cover glass (see the figure above) in such a
way that your face will be protected, at the utmost.
- Use always safety glasses.
ADJUSTING THE TOOL REST.
Disconnect the machine and make sure the grin-
ding stone has stopped before adjusting the tool
rest.
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.
Disconnect the machine and make sure the grinding
stone has stopped before replacing the grinding
stone. Disconnect the machine and make sure the grinding
stone has stopped before replacing the grinding stone.
Required tools:
- spanner, 19 mm;
- spanner, 8 mm;
- screwdriver.
- 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 con-
cave side facing the grinding stone. Slide the new grin-
ding stone on to the spindle. Replace the second
flange on the spindle,
with the concave side facing the grinding stone. Tigh-
ten 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.
