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 grinding wheels 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
and brackets.
Important.
Prior to fitting the eye shield brackets, ensure
the grinder is turned off and the power plug is removed
from the socket.
Note.
Always check to ensure the eye shields (1) are
correctly fitted and the eye shield brackets (9) are
correctly adjusted each time the grinder is used. Eye
shields and brackets must be fitted over each grinding
wheel on all the bench grinders in the range, except the
sharpening wheel (11) on Model NTS2000A.
1. Remove the top screw of
the wheel guard (8).
2. Fit the eye shield bracket (9).
3. Fit a flat steel washer on to
the wheel guard screw and
then pass the screw through
the eye shield bracket,
guard and then the eye
shield bracket again. Fit
another flat washer,
followed by the spring washer and then the nut.
Tighten the nut so the bracket can slide.
4. Fit the eye shield (1) to the top of the bracket. Secure
the eye shield by passing the 45mm x 5mm screw
through both the bracket
(9) and eye shield (1).
Tighten the screw to the
point where the eye shield
will move with firm
resistance.
5. Slide the eye bracket
inward or outwards so the
edge of the bracket is less
than 6mm from the surface
of the wheel as shown, but not touching the wheel.
6. Rotate the wheel by hand one full revolution to ensure
the wheel can rotate without contacting the bracket.
Firmly tighten the screw retaining the bracket.
Important.
Ensure that the washers as shown in the
photograph are correctly positioned.
Fitting the tool rests.
The tool rests (7) are required for each high speed
grinding wheel to assist in the grinding operation. (They
are not required on the sharpening wheel on the
NTS2000A).
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 tool rests supplied are left or right handed.
Important.
Prior to fitting the tool rests, ensure the
grinder is turned off and the power plug is removed from
the socket.
1. Remove the lower screw on
the wheel guard (8).
2. Hold the tool rest (7) in
the correct position against
the outer surface of the
inner wheel guard. Fit the
screw through the tool rest
and then both sides of the
guard ensuring the square
