6" BENCH GRINDER WITH LAMP
WARNING
: Always wear proper personal hearing protection that
conforms to ANSI S12.6 (S319) during use. Under some conditions and
duration of use, noise from this product may contribute to hearing loss.
GROUND TOOLS (ELECTRICAL POWERED CONNECTIONS)
Only use qualified repair agents to service this power tool. Only use
qualified electrician to repair any dam aged wiring.
NEVER remove the grounding prong from the power tool or extension
cord. This product must be grounded. In the event of a malfunction or
break down, grounding provides a path of least resistance for electric
current to reduce the risk of electric shock. This product is equipped
with an electric cord having an equipment-grounding conductor and a
grounding plug. The plug must be plugged into a matching outlet that is
properly installed and grounded in accordance with all local codes and
ordinances. DO NOT modify the plug provided. If it will not fit the outlet,
have the proper outlet installed by a qualified electrician. Check with a
qualified electrician or service personnel if the grounding instructions are
not completely understood, or if in doubt as to whether the product is
properly grounded.
Repair or replace a damaged or worn cord immediate ly. This product is
for use on a nominal 120V circuit and has a grounding plug. Only connect
the product to an outlet having the same configuration as the plug. DO
NOT use an adapter with this product.
EXTENSION CORDS
When using this tool at a considerable distance from the power source, a
conductor, grounding-type extension cord of adequate size must be used for
safety and to prevent loss of power and over-heating. For a 120 Volt tool, the
minimum size of the wires in any extension cord up to 75' long must be 18
gauge (American Wire Gauge). If the total extension cord length is from 75' to
100', 16 gauge wire is required throughout the tension.
NOTE:
The 16 gauge wire is heavier than the 18 gauge and will carry
current for a longer distance without a voltage drop.
Use only 3 wire extension cords which have 3 prong grounding type plugs
and 3 hole receptacles which accept the tool’s plug. Replace or repair
damaged or worn cord immediately.

6" Bench Grinder is used for hand grinding operations
such as sharpening chisels or screwdrivers, grinding drills, removing
excess metal from work pieces and smoothing metal surfaces. It
features ball bearing construction for smooth operation, adjustable and
shatterproof eye shields, spark breakers, tool rests and removable wheel
guards. It has a goose neck lamp to illuminate the work area.

ASSEMBLY
TOOL RESTS
Attach the left and right tool rests with the (4) 5/8" bolts and large
washers. Adjust the rests for a distance of 1/16" from the surface of the
grinding wheel.
SPARK BREAKERS
Attach the spark breakers with the (2) 5/16" bolts and medium washers.
Adjust the spark breaker for a distance of 1/16" from the surface of the
grinding wheel. Spark breakers should be installed perpendicular to the
grinding wheel. If these are not installed properly, it is an OSHA violation.
EYE SHIELDS
Select one of the eye shields. Put its clamp into one of the other spark
breaker brackets. Adjust the eye shield to be located in the middle of the
wheel to protect the operator from sparks.
FINAL ASSEMBLY
Fasten the Grinder to the workbench, stand or cabinet. Two holes are
provided in the base of the Bench Grinder to attach the grinder securely
and prevent it from moving during operation.
OPERATION
A Bench Grinder is designed for hand grinding operations such as
sharpening chisels or screwdrivers, grinding drills, removing excess
metal from work and smoothing metal surfaces. A medium grain
abrasive grinding wheel is suitable for rough grinding where a
considerable amount of metal has to be removed or where a smooth
finish is not important. For sharpening tools or grinding to close limits
of size, a fine grain wheel should be used as it removes metal slower
and gives the work a smooth finish.
1. Adjust the eye shield.
2. Check for a 1/16" clearance between the tool rests and the grinding
wheels and between the spark breakers and the grinding wheels.
Adjust as needed. Always keep the tool rest adjusted so that it just
clears the wheel and is at the same level or just below the center line
of the wheel to prevent accidental jamming of the work between the
tool rest and the wheel.
3. Turn the Bench Grinder on and let it come up to speed.
CAUTION
: When starting the Bench Grinder, turn it on and stand to
one side until it has come up to speed. There is always the possibility that
a piece from a damaged grinding wheel may be thrown off when coming
to full speed.
1. When grinding, always keep the work moving across the face of
the wheel. Grinding against the same spot on the wheel will cause
grooves to be worn into the face of the wheel. For grinding large or
odd shaped work pieces, the tool rests can be removed if needed.
2. When it is necessary to reshape the grinding wheels, use the proper
tools. After re-shaping, adjust the tool rests and spark breakers as
needed to maintain the 1/16" clearance from the wheel.
CHANGING THE GRINDING WHEEL
1. Unplug the bench grinder.
2. Remove the outer wheel guard cover screws and the wheel
guard cover.
3. Hold the opposite wheel firmly. Remove the nut and flange.
NOTE
Turn the spindle nut on the right hand side counterclockwise to
loosen. Turn the spindle nut on the left hand side clockwise to loosen.
4. Remove the old wheel and replace it with the new one.
5. Assemble the flange and nut onto the spindle. Tighten the spindle
nut just enough to hold the wheel firmly. If the nut is tightened too
much, the wheel may be damaged.
6. Attach the wheel guard cover.
7. Turn the grinder on and let it come up to speed and idle for
one minute.
BENCH MOUNTING
Mounting the grinder on a bench is strongly recommended in order to prevent
movement of the grinder when pressure is applied against a wheel.
1. Slide rubber feet on both sides and in the middle of the grinder base.
2. Drill 2 holes for 1/4" wood screws or bolts in the bench.
3. Use 1/4" wood screws or bolts and tighten down only enough to
partially compress the rubber feet (about 1/16"). The rubber feet will
not be effective in absorbing vibration if fully compressed.
4. When using 1/4" bolts, a second nut is required to lock against the
first nut and keep the grinder from loosening during operation.
5. Never operate the grinder without the rubber feet attached to its base.
