APPLICATIONS
This product has been designed only for the purposes listed
below:
 Sharpening drill bits
 Sharpening lawn mower blades
 Sharpening chisels and flat screwdrivers
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 chis-
els, planer blades, scissors, etc., and for removing rust or
corrosion. Grinders remove material rapidly so pressure is
the key to efficient grinding.

OPERATION

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 8, page 15.
The Bench Grinder features a front access On/Off switch for
convenience and safety.
SHARPENING TWIST DRILL BITS
See Figure 9, page 15.
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 10, page 15.
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 ad-
ditional material.
CAUTION:
An unbalanced lawn mower blade may cause excessive
vibration which will damage the lawn mower.
SHARPENING CHISELS AND SCREWDRIVER
BLADES
See Figure 11, page 15.
When sharpening chisels and screwdrivers, work rest should
support the chisel at the correct angle against the wheel.
