3. Drill appropriate sized holes.
4. Insert ¼” (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.1)
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 ( 2950 rpm ) . 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, on the base.
To turn the tool on depress the side of the rocker switch on
the right side, marked “1”. To turn off the grinder, depress the
left side of the rocker switch, marked “ O ”.
Changing Accessories (Fig. 2)
Turn off the tool and disconnect from power supply. Use only
wheels that measure in diameter. This tool has 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.
Caution
: To reduce the risk of fire, use 10 watt
max. appliance bulb.
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.
