Caution. During use it is important not to overload the
grinder. The grinder should run at close to full speed. If
you are applying too much pressure the grinder will start
to slow down. Under these conditions, remove the part
being ground and allow the grinder to return to full
speed. Re-apply the part to the grinder, but with a little
less force.
All of the grinders are supplied with grinding wheels
designed for metal use only. The grinding of Copper, Brass,
Aluminium, Wood or other similar materials will “clog” the
grinding wheel.
Warning. Never attempt to grind Magnesium.
Fitting and adjusting the eye shields
Important. Prior to fitting the eye shields, ensure the
grinder is turned off and the power plug is removed from
the socket.
Note. Always check to ensure the eye shields are correctly
fitted each time the grinder is used. Eye shields must be
fitted over each grinding wheel on all bench grinders in
the range.
1. The MagniVision eye shield (1) features a magnifying
glass incorporated into the design to provide greater
visibility and improved accuracy.
2. Take the MagniVision eye shield and fit it to the top of
the right hand side light assembly. The other eye shield
(2) should be installed on the left hand side.
3. Fit a plastic coated screw
through each side of the eye
shield into the pivot points on
the light assembly and
tighten firmly to the point
where the shield is secure, but
still able to be adjusted up
and down.
The securing screws are plastic
coated so they can be adjusted at any time without the
use of tools.
Fitting and adjusting the spark deflectors
1. The spark deflectors (12) are already fitted to the
bench grinder but will need to be adjusted prior to use,
and then over time to compensate for wheel wear.
2. To adjust the spark deflectors
loosen the screw using the
allen key supplied.
3. Slide the spark deflector up or
down so that the bottom edge
is less than 6mm from the
surface of the wheel, but not
touching the wheel.
4. Rotate the wheel by hand one
full rotation to ensure the
wheel can rotate without
contacting the spark deflector.
Firmly tighten the screw
retaining the spark deflector.
Fitting the tool rests
The tool rests (10) are required for each high speed
grinding wheel to assist in the grinding operation.
Caution. Never use a Bench Grinder on which the tool rest
has not been fitted or where the tool rest has not been
correctly adjusted.
The right hand side tool rest features an indentation that
helps you rest your work piece for more accurate grinding.
