on the Polisher to make sure the spark deflec-
tor doesn't hit the grinding wheel.
• Always make sure your bench grinder is
securely mounted to a workbench or an ap-
proved workstand. Failure to do so could
result in an accident resulting inpossible
serious personal injury.
MOUNTING SAFETY SHIELDS
Mount the left and right shield rods to the inside
of the wheel guards using the clamp brackets,
hex bolts, and washers.
Once shield rods are firmly in place, slide the
shield bracket onto the shield rod. Tighten the
carriage bolt leaving it loose enough to allow
the safety shield to be raised and lowered easily.
WORK REST
Using the hex bolt and washer, secure the work
rest against the inside of the wheel guard.
Before tightening the bolts, adjust the gap be-
tween the grinding wheel and the work rest to
a maximum of 1/16" (1,6 mm). Tighten securely.

OPERATION

WARNINGS:
• Do not attempt to operate this tool until you
have read thoroughly and understand completely
all instructions, safety rules, etc., contained in this
manual. Failure to comply can result in accidents
involving fire, electric shock, or serious personal
injury. Save this operator's manual and review
frequently for continuing safe operation and
instructing others who may use this tool.
• To prevent personal injury, never operate the
bench grinder unless the safety shields and spark
deflectors are properly installed and in place
• Never sharpen or grind anything made of
aluminum.
• Excessive pressure on a cold wheel may cause
the wheel to crack.
IMPORTANT
• Always wear safety goggles or safety glasses
with side shields during power tool operation or
when blowing dust. If operation is dusty, wear a
dust mask.
• When grinding, metal objects become heated
quickly. It is important to keep moving the object
back and forth across the grinding wheel and to
10
cool the object frequently.
To be efficient and work as designed, your tools
should be kept sharp. Dull tools can and will
cause accidents.
Bench Grinders are ideal for sharpening tools
such as chisels, planer blades, scissors, etc., and
for removing rust or corrosion.
Grinders remove material rapidly so pressure is
the key toefficient grinding.The proper way to
sharpen a tool and avoid overheating is: Keep
the object in constant motion, moving it at an
evenpace. Never force a tool against the grinding
wheel. Keep the tool cool by using a pan of water.
The grinding wheel should rotate "into" the
object being sharpened.
Note: Excessive pressure may damage the tool,
cause themotor to overheat, and prematurely
wear down the grinding wheel.
WHEEL REPLACEMENT
If you must replace a grinding wheel, be sure to
obtain one with a safe rated speed greater than
the "no load speed" rpm marked on the data
plate of the grinder.
To replace the grinding wheel, remove the wheel
cover by loosening the screws. Loosen the wheel
nut in a clockwise direction for the left side and
a counterclockwise direction for the right side.
Remove the outer flange and grinding wheel.
To install a new plate, reverse the above pro-
cedure. Be sure the grinding wheel and outer
flange are properly seated on the spindle shaft.

EQUIPMENT MANAGEMENT

If you use steel cable sling, protect the bench Pol-
isher using felt or cloth to protect the paint.
The Bench Polisher
must be holding
like shows on the
