WORK REST-EBG2515/EBG3720
See Figure. 6
Mount the work rests to the work rest bracket using the
knob, washer, and one hex nut.
Before tightening the bolts, adjust the gap between the
grinding wheel and the work rest to a maximum of 1.6mm.
Tighten securely.
Keep the object in constant motion, moving it at an
even pace.
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, 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:
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.
WARNING:
Excessive pressure on a cold wheel may cause the wheel
to crack.
WARNING:
Never sharpen or grind anything made of aluminium.
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.

The following recommendations will help you sharpen
specific tools:
TWIST DRILL BITS
see Figure 7.
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.
Note: Excessive pressure may damage the tool, cause
the motor to overheat, and prematurely wear down the
grinding wheel.

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.
