Installing eye shields (Fig. A)
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

Warning! 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 (3450 rpm or
57.55s-1 ). 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.
Caution! Continuous operating time 30 min, with 15 min
intervals for rest.
SWITCH
The switch is located on the front of the grinder, 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. B)
Turn off the tool and disconnect from power supply. Use
only wheels that measure 6" (152 mm) in diameter. This
tool has 1/2" (13 mm) 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" (1,5mm) from
the accessory and tighten securely.
