BASIC OPERATION
WARNING:
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.
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.
WARNING:
Never sharpen or grind anything made of aluminum.
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 even
pace.
■ Never force a tool against the grinding wheel.
■ Keep the tool cool by using either a cooling tray or a pan
of water.
■ The grinding wheel should rotate “into” the object being
sharpened.
Note: Excessive pressure may damage the tool, cause the
motor to overheat, and prematurely wear down the grinding
wheel.
WARNING:
Excessive pressure on a cold wheel may cause the wheel
to crack.
The following recommendations will help you sharpen
specific tools:
TWIST DRILL BITS
See Figure 8.
Drill bits are best sharpened on a sharpening jig (available
at most hardware stores). Begin on one side of the point
at the existing angle, then twist the bit while maintaining
contact with the grinding surface. Sharpen only the tip.

LAWN MOWER BLADES
See Figure 9
.
Lawn mower blades are usually sharpened on only one
edge and dressed up slightly on the other. Perform this
sharpening process on both cutting ends of the blade. After
sharpening, be sure to balance the blade by removing
additional material.
WARNING:
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.
CAUTION:
An unbalanced lawn mower blade may cause excessive
vibration which will damage the lawn mower.
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
important to the efficiency of your bits. One work rest has
a V-groove angled to fit most drill bits.
