SAFETY GUIDELINES
ADDITIONAL SPECIFIC SAFETY RULES
1. DO NOT operate this machine until it is completely assembled and installed according
to the instructions. A machine incorrectly assembled can cause serious injury.
2. OBTAIN ADVICE from your supervisor, instructor, or another qualified person if you are
not thoroughly familiar with the operation of this machine. Knowledge is safety.
3. FOLLOW ALL WIRING CODES and recommended electrical connections to prevent
shock or electrocution.
4. ALWAYS USE THE PROVIDED BLOTTER and wheel flanges to mount the grinding wheels
on the grinder shaft to prevent wheel damage or accidental separation. Separation can
result in fragments flying off the wheel at high speeds.
5. USE ONLY WHEELS suitable for the speed of the machine. Unsuitable grinding wheels
can come apart, throwing fragments out at high speeds.
6. USE ONLY WHEELS that have a bore exactly equal to the arbours of the machine. Never
attempt to machine an undersized wheel to fit an arbour. Unsuitable grinding wheels
can come apart, throwing fragments out at high speeds.
7. DO NOT overtighten wheel nut.
8. DO NOT USE A WHEEL THAT VIBRATES. Dress the grinding wheel, replace it, or
replace the bearings of the shaft. Unsuitable grinding wheels can come apart, throwing
fragments at high speeds.
9. INSPECT WHEELS before starting the machine for cracks or fragments. REPLACE
DAMAGED WHEELS immediately. Parts of the wheel can be thrown at high speeds
causing serious injury.
10. ADJUST EYE SHIELDS close to the grinding wheel, and re-adjust as the wheel wears
down. Flying sparks are dangerous and can cause fires or explosions.
11. ALWAYS MAKE SURE the eye shields are in place, properly adjusted, and secured.
12. ADJUST TOOL RESTS close to the grinding wheel (1/8"separation or less). Tighten the
tool rest securely to prevent shifting positions, and re-adjust as the wheel wears down.

SAFETY GUIDELINES
13. STAND TO ONE SIDE before turning the machine on . Loose fragments or wheel parts
could fly from the wheel at high speeds.
14. NEVER GRIND ON A COLD WHEEL. Run the grinder for one full minute before
applying the workpiece. A cold wheel has a tendency to chip. Those fragments could
fly from the wheel at high speeds.
15. NEVER START THE MACHINE with the workpiece against the grinding wheel. The
workpiece can be drawn into the wheel, causing damage to the machine and/or
serious injury.
16. CLEAN THE MACHINE thoroughly when processing different types of workpieces
(wood, steel, or aluminium). Combining wood and metal dust can create an explosion
or fire hazard. DO NOT GRIND or polish magnesium. Fire will result.
17. NEVER GRIND NEAR FLAMMABLE GAS OR LIQUIDS. Sparks can create a fire or an
explosion.
18. AVOID awkward operations and hand positions. A sudden slip could cause a hand to
move into the grinding wheel.
19. KEEP ARMS, HANDS, and fingers away from the wheel. The abrasive surfaces can
cause serious injury.
20.HOLD THE WORKPIECE FIRMLY against the tool rest. Loss of control of the
workpiece can cause serious injury.
21. DRESS THE WHEEL on the face only. Dressing the side of the wheel could cause it to
become too thin for safe use.
22. GRIND A WORKPIECE using the face of the grinding wheel only. Loss of control of the
workpiece can cause serious injury.
23. NEVER APPLY COOLANT directly to the grinding wheel. Coolant can weaken the
bonding strength of the grinding wheel and cause it to fail. Dip the workpiece in water
to cool it.
24. DO NOT TOUCH the ground portion of a workpiece until it has cooled sufficiently.
Grinding creates heat.
25. PROPERLY SUPPORT LONG OR WIDE workpieces. Loss of control of the workpiece
can cause serious injury.
26. NEVER PERFORM LAYOUT, assembly , or set-up work on the table/work area when
the machine is running. A sudden slip could cause a hand to move into the wheel.
Severe injury can result.
27. TURN THE MACHINE OFF, disconnect the machine from the power source, and clean
the table/work area before leaving the machine. Lock the switch in the “OFF” position
to prevent unauthorized use. Someone else might accidentally start the machine and

machine to the power source, make sure the switch is in the "OFF" position.
GROUNDING INSTRUCTIONS
All grounded, cord-connected machines: In the event of a malfunction or breakdown,
grounding provides a path of least resistance for electric current to reduce the risk of
electric shock. This machine is equipped with an electric cord having an equipment
grounding conductor and a grounding plug.
DANGER!
DO NOT EXPOSE THE MACHINE TO RAIN OR OPERATE THE MACHINE IN
DAMP LOCATIONS.
THIS MACHINE MUST BE GROUNDED WHILE IN USE TO PROTECT
THE OPERATOR FROM ELECTRIC SHOCK.
!
DANGER!
IMPORTANT INFORMATION
The plug must be plugged into a matching outlet that is properly installed and grounded in
accordance with all local codes and ordinances.
Do not modify the plug provided–if it will not fit the outlet, have the proper outlet installed
by a qualified electrician.
Improper connection of the equipment-grounding conductor can result in risk of electric
shock. The conductor with insulation having an outer surface that is green with or without
yellow stripes is the equipment-grounding conductor. If repair or replacement of the
electric cord or plug is necessary, do not connect the equipment-grounding conductor to a
live terminal.
Check with a qualified electrician or service personnel if the grounding instructions are not
completely understood, or if in doubt as to whether the machine is properly grounded.
Use only 3-wire extension cords that have 3-pronged grounding type plugs and matching
3-conductor receptacles that accept the machine’s plug, as shown in Fig. A.
Repair or replace damaged or worn cord immediately.
IN ALL CASES, MAKE CERTAIN THE RECEPTACLE IN QUESTION
IS PROPERLY GROUNDED. IF YOU ARE NOT SURE, HAVE A
QUALIFIED ELECTRICIAN CHECK THE RECEPTACLE.
Use proper extension cords. Make sure your extension cord is in good condition
and is a 3-wire extension cord which has a 3-pronged grounding type plug and matching
receptacle which will accept the machine’s plug. When using an extension cord, be sure to
use one heavy enough to carry the current of the machine. An undersized cord will cause a
drop in line voltage, resulting in loss of power and overheating. The table shows the correct
gauge to use depending on the cord length. If in doubt, use the next heavier gauge. The
smaller the gauge number, the heavier the cord.

TWIST DRILL BITS
Drill bits are best sharpened on a
sharpening jig, available at most
hardware stores, but can be “dressed
up” on your grinder. Begin on one
side of the point at the existing angle,
then twist the bit while maintaining a
constant angle with 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. One tool
rest has a V-groove that is correctly
angled for most drill bits.
COOLANT TRAY
When grinding, metal objects
become heated quickly. It is
important to keep moving the object
back and forth across the face of the
grinding wheel and to cool the object
frequently using the coolant tray.
