wheel guard. Adjust the spark deflectors to
within 1/16" (1,6 mm) of the grinding wheel.
Tighten screws securely.
WARNINGS:
• Always spin the wheel by hand before turn-
ing on the grinder to make sure the spark de-
flector 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 eas-
ily.
WORK REST
Using the hex bolt and washer, secure the work
rest against the inside of the wheel guard. Be-
fore 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 se-
curely.
OPERATION INSTRUCTIONS
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 fre-
quently for continuing safe operation and in-
structing 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 opera-
tion is dusty, wear a dust mask.
• When grinding, metal objects become heated
quickly. It is important to keep moving the ob-
ject back and forth across the grinding wheel
and to 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 to efficient 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 ro-
tate "into" the object being sharpened.
NOTE: excessive pressure may damage the tool,
cause themotor to overheat, and prematurely
wear down the grinding wheel.
THE FOLLOWING RECOMMENDATIONS WILL
HELP YOU SHARPEN SPECIFIC TOOLS
TWIST DRILL BITS
Drill bits are best sharpened on a sharpening
jig. Begin on one side of the point at the exist-
ing angle, then twist the bit while maintain-
ing contact with the grinding surface. Sharpen
only the tip.
This technique requires considerable practice,
so take your time and make a few "dry runs"
first with the grinder off. Be sure to maintain
the original cutting edge angle as this is impor-
tant to the efficiency of your bits. One work
rest has a v-groove angled to fit most drill
bits.
CHISELS AND SCREWDRIVER BLADES
When sharpening chisels and screwdrivers,
work rest should support the chisel at the cor-
rect angle against the wheel.
WHEEL REPLACEMENT
If you must replace a grinding wheel, be sure
