MOUNTING
Bench mounting
1. The grinder should be unplugged.
2. Position grinder on workbench. Check for the
availability of power for the grinder. Mark location
of holes for drilling.
3. Drill appropriate sized holes.
4. Insert 1/4" (6mm) Hex head bolts through washers
and the holes. You may want to use washers on the
underside of the bench as well.
5. Tighten the nuts. Do not overtighten. Allow the rubber
feet to absorb the vibration when the grinder is running.
Installing eye shields (Fig. B)
Turn off tool and disconnect from power supply. Adjust the
eye shields so they are between the wheels and your eyes.
Note: Eye shields are not designed to replace safety glasses.
Installing tool rests
Turn off power and disconnect from power supply. Use the
bolts, washers, spacers and lock nuts from the plastic bag
to secure the brackets and tool rests in place.
Caution! Use the washers and screws supplied. Longer
screws may interfere with the movement of the grinding
wheel.
OPERATION
Never use a bench grinder if it is not firmly fastened to a
work bench or rigid frame. Before turning the grinder on,
put on safety glasses. Turn on the grinder and allow it to
reach full speed (120V 3450rpm), (127/220V 3450rpm)
and (220V 2950rpm). Hold the workpiece firmly and
against the tool rest. Hold very small pieces with pliers or
other suitable clamps. Feed the work smoothly and evenly
into the grinding wheel. Move the work slowly and avoid
jamming the work against the wheel.
As the wheel tends to slow down you should occasionally
release the pressure to let the wheel return to full speed.
Grind only on the face of the grinding wheel and never on
the side. (Some wheels are designed for side grinding and
will say so on their instruction sheets).
Caution! Prolonged grinding will cause most materials
to become hot. Handle them with pliers.
SWITCH
The switch is located on the front of the grinder (Fig. B), on
the base. To turn the tool on depress the side of the rocker
switch on the right side, marked "ON". To turn off the grinder,
depress the left side of the rocker switch, marked "OFF".
Changing accessories (Fig. C)
Turn off the tool and disconnect from power supply.
Use only wheels that measure 6" (152mm) in diameter.
This tool has 1/2" (13mm) arbors on both sides.
Follow the steps below to remove and replace an
accessory:
1. Loosen and pull the tool rest out as far as possible.
Do not remove it.
2. Remove the three screws from the side of the wheel
cover and remove the cover.
3. Insert a flat bladed screwdriver into the slot in the left
end of the grinder's rotor shaft. Hold the screwdriver
firmly to keep the shaft from turning as you loosen and
remove the hex nut in the center of the grinding wheel
or other accessory.
4. Remove the wheel washer and the wheel.
5. Inspect the wheel for cracks, chips or any other visible
damage (other than normal wear) and discard if such
damage is found. Inspect the blotters for damage.
If the blotters are missing or severely damaged,
replace them with pieces of thin cardboard or blotter
paper cut in the same shape. Never use a grinding
wheel without a blotter on each side of the wheel.
6. Install the new wheel or other accessory. Be sure that
both wheel washers are in place (concave sides
toward wheel). Use only flanges furnished with the
grinder.
7. Hold as before and tighten the nut firmly but do
not overtighten. Overtightening can crack a
grinding wheel.
8. Replace the wheel cover and its screws.
9. Adjust the tool rest to at least 1/16" (2mm) from the
accessory and tighten securely.
MAINTENANCE
Your tool has been designed to operate over a long period
of time with a minimum of maintenance. Continuous
satisfactory operation depends upon proper tool care and
regular cleaning.
Warning! Before performing any maintenance, switch
off and unplug the tool.
f Regularly clean the ventilation slots in your tool using
a soft brush or dry cloth.
f Regularly clean the motor housing using a damp cloth.
Do not use any abrasive or solvent-based cleaner.
CLEANING
Blowing dust and grit out of the wheel guards using
compressed air is a necessary regular maintenance
procedure. Dust and grit containing metal particles often
accumulate on interior surfaces and could create an
electrical shock hazard if not frequently cleaned out.
Always wear safety glasses.
