Installing or Changing the Grinding Wheel (Figure 8)
WARNING!
• Turn the power off and remove the plug from the outlet before changing the grinding wheels.
When turning the grinder on with a newly installed wheel, DO NOT STAND IN FRONT OF THE
GRINDER. Stand to the side and allow the grinder to run for at least one minute before using it.
• Check grinding wheel frequently for wear or damage. Replace cracked wheels IMMEDIATELY.
Replace worn wheels before the diameter reaches 4".
• Replacement grinding wheels must not exceed the maximum size on the grinder nameplate
and have a safe rated speed equal to or greater than the "No Load" speed on the nameplate.
CAUTION!
• Do not over tighten the wheel nut, because this may cause the wheel to crack.
• DO NOT INSTALL OR USE A DAMAGED GRINDING WHEEL. The force of rotation may cause a
damaged wheel to fly apart, and could injure operators or bystanders.
• Follow grinding wheel manufacturer's installation and use instructions.
1.Remove the tool rest knob, tool rest bracket and tool rest.
2.Use a screwdriver to remove the wheel cover screws and remove the wheel cover.
3.Loosen the grinding wheel nut using a hex or adjustable wrench. Rotate right wheel
nut counterclockwise to loosen. Rotate left wheel nut clockwise to loosen.
5.Remove nut, outer wheel flange, paper washers and wheel.
6.Inspect the new wheel carefully to ensure there are no cracks, chips or other damage.
7.Wipe the wheel flange surfaces clean, and install new grinding wheel in reverse order of
removal (including paper or fiber washers on both sides of wheel between wheel and flanges).
Note: Be sure the grinding wheel and outer flange are properly seated on the spindle shaft.
8.Tighten wheel retaining nut snug, without over-tightening. Over-tightening can damage wheel.
9.Replace the wheel cover.
10.Reposition the tool rest, spark deflector and eye shields to fit the new wheel.
11.Standing away from the rotational plane of the new wheel, turn on the grinder and allow it to
run at full speed for several minutes before use.

20.DIRECTION OF FEED. Feed work into a blade or cutter against the direction of rotation of the
blade or cutter only.
21.NEVER LEAVE TOOL RUNNING UNATTENDED. Turn Power OFF. Don't leave tool until it comes to
a complete stop.

GENERAL SAFETY RULES
ELECTRICAL SAFETY
Grounding Instructions
1. (SEE FIGURE 1) 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 tool is equipped
with an electric cord having an
equipment-grounding conductor and a
grounding plug. The plug must
be plugged into a matching outlet that is
properly installed and grounded in accordance
with all local codes and ordinances.
2. Do not modify the plug provided - if it will not fit the outlet, have the proper outlet installed by
a qualified electrician.
3. Improper connection of the equipment-grounding conductor can result in a 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.
4. Check with a qualified electrician or service personnel if the grounding instructions are not
completely understood, or if in doubt as to whether the tool is properly grounded.
5. Repair or replace damaged or worn cord immediately.
Extension Cords
1. Make sure your extension cord is in good condition. When using an extension cord, be sure to
use one heavy enough to carry the current your product will draw. An undersized cord will
cause a drop in line voltage resulting in loss of power and overheating. Table 1 (page 3) shows
the correct size to use depending on cord length and nameplate Ampere rating. If in doubt, use
the next heavier gauge. The smaller the gauge number, the heavier the cord.
2. Use only 3-wire extension cords that have 3-prong grounding plugs and 3-pole receptacles that
accept the tool's plug.
3. Do not abuse the cord. Never use the cord to carry the tools or pull the plug from the outlet.
4. Keep cord away from heat, oil, sharp edges or moving parts. Replace damaged cords
immediately. Damaged cords increase the risk of electrical shock.
5. When operating a power tool outside, use an outdoor extension cord marked "W-A" or "W".
These cords are rated for outdoor use and reduce the risk of electrical shock.
