BASIC OPERATION
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, 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 even
pace.
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
the motor to overheat, and prematurely wear down the
grinding wheel.
ON/OFF SWITCH
See Figure 10, page 12.
The bench grinder features a front access on/off switch for
convenience and safety.
SHARPENING TWIST DRILL BITS
See Figure 11, page 13.
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.
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.
SHARPENING LAWN MOWER BLADES
See Figure 12, page 13.
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.
NOTICE:
An unbalanced lawn mower blade may cause excessive
vibration which will damage the lawn mower.
SHARPENING CHISELS AND SCREWDRIVER
BLADES
See Figure 13, page 13.
When sharpening chisels and screwdrivers, work rest should
support the chisel at the correct angle against the wheel.
