INSTALLATION
Fig. C
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 vibra-
tion.
ASSEMBLY AND ADJUSTMENT OF EYE
SHIELD BRACKET AND EYE SHIELD
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.
•
Fix the eye shield bracket (4) with attached eye shield
to the grinding wheel cover, using the screw provi-
ded (A).
•
Set the eye shield bracket at the correct height. The
clearance (B) between the wheel and the eye shield
bracket should be 1 to 1.5 mm.
•
Next tighten the screw (A) firmly.
•
Position the eye shield to give maximum protection
when working.
•
Always wear safety glasses.
FITTING AND ADJUSTING TOOL REST
The tool rest should only be adjusted when the grin-
ding wheel is completely stationary, and the
machine is disconnected from the power supply (the wall soc-
ket).
•
Fit the tool rest as shown in Fig. C.
•
Fix it as tightly as possible in position, with a maxi-
mum clearance (C) of 1 – 1.5 mm between the tool
rest and the grinding wheel.
If the grinding wheel is worn down to the point where the
wheel guard can no longer be adjusted to this distance
( 1 - 1,5 mm ), the grinding wheel must be replaced.
REPLACING THE GRINDING WHEEL
Fig. D
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 lis-
ted 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 grin-
ding.

SPECIAL SAFETY GUIDELINES
WHEN USING THE MACHINE FOR THE
FIRST TIME
•
Check the following:
•
Does the voltage rating of the bench grinder corre-
spond to the power supply?
•
Is an earthed mains power socket available?
•
Are the power cord and plug in good condition (solid,
without fraying or other damage)?
•
Avoid the use of long extension cords. The exten-
sion cords you use must always be earthed.
•
A grinding wheel is a brittle toolpiece. The stone is
not resistant to knocks. Always grind on the front
edge of the grinding wheel, and never on the side of
the grinding wheel. Never fit a cracked grinding
wheel. Replace it immediately, as the high rotational
speed could cause the stone to fly apart, causing a
serious accident.
•
Always wear safety glasses when grinding.
•
Never grind without the cover fitted over the grin-
ding wheel.
•
Always fit the grinding wheel cover and tool rest
tightly, and with the correct clearance.
•
Never allow more than 1-1.5 mm clearance between
tool rest and grinding wheel.
•
Only use the grinding wheel for the work it was
designed for (for example sharpening tools), and
NOT for heavy construction work. The following
information must be available, before you fit any new
grinding wheel:
•
Details about the manufacturer.
•
Binding material.
•
Dimensions.
•
Permissible rotational speed.
•
Never ream out the hole in a grinding wheel to a lar-
ger diameter.
•
The maximum rotational speed of the grinding wheel
should never be allowed to exceed the maximum
speed given for the wheel.
•
Never use any grinding wheel that is damaged or
deformed.
•
In order to be able to grind safely, the machine must
be firmly bolted to a workbench.
•
The tool rest should be replaced whenever the width
of the tool rest measures less than 20 mm.
•
The recommended depth of the recess in the flange
(T) is 2 mm and the diameter of the spindle hole is 13
mm (see Fig. B).

WHENEVER USING THE MACHINE
•
Check that the switch is NOT in the ‘ON/1’ position
before connecting the machine to the power supply.
•
Always keep the power cord out of the way of the
tool’s moving parts.
IMMEDIATELY SWITCH OFF THE MACHINE
WHENEVER:
•
The plug or power cord is defective or damaged.
•
The switch is defective.
•
You smell smoke or burning insulation.
ELECTRICAL SAFETY
Always be certain that your mains power supply
corresponds with the rating on the type plate.
When replacing power cords or plugs
Immediately dispose of old plugs as soon as they are
replaced with new ones. It is dangerous to plug a loose
power cord into the mains power supply.
When using extension cords
•
The grinder is fitted with a triple-core power cord
and an earthed mains plug. Therefore always use a
mains power socket that is also earthed. Should you
need an extension cord, always use a triple-core
extension with earthed plug and socket.
•
The cores should have a cross-section of at least 1.5
mm
