Specific safety rules for the spindle sander
WARNING: Do not operate the spindle sander until it is fully assembled and you
have read and understood the following instructions and the warning labels on the
spindle sander.
1. Know the condition of the spindle sander. If any part is missing, bent, or does not operate
properly, replace the part before using the sander.
2. Determine the type of work you are going to be doing before operating the spindle sander.
3. Secure your work. Support the workpiece securely on the table, and hold it with both hands.
4. Be aware of the direction of feed. Feed the workpiece into the sanding sleeve against the
direction of rotation of the sanding sleeve.
5. Always keep your hands out of the path of the sander and away from the sanding sleeves.
Avoid hand positions where a sudden slip could cause your hand to move into the spindle. Do
not reach underneath the workpiece or around the sanding sleeve while the spindle is rotating.
6. Disconnect the sander after turning off the power switch. Wait for the spindle to stop rotating
before performing maintenance. The sander must be disconnected when not in use or when
changing accessories, sanding sleeves, rubber spindles, or other items.
7. Make sure there are no nails or other foreign objects in the area of the workpiece to be sanded.
8. Never use this sander for wet sanding. Failure to comply may result in electric shock causing
serious injury or worse.
9. Use only identical replacement parts when servicing this spindle sander.
10. Make sure the spindle has come to a complete stop before touching the workpiece.
11. Take precautions when sanding painted surfaces. Sanding lead-based paint is NOT
RECOMMENDED. The contaminated dust is too difficult to control, and could cause lead
poisoning. When sanding paint:
• Protect your lungs. Wear a dust mask or respirator.
• Do not allow children or pregnant women in the work area until the paint sanding job is
finished and the clean-up is completed.
• Do not eat, drink, or smoke in an area where painted surfaces are being sanded.
• Use a dust collection system when possible. Seal the work area with plastic. Do not track paint
dust outside of the work area.
• Thoroughly clean the area when the paint sanding project is completed.

Electrical information
Grounding Instructions
IN THE EVENT OF A MALFUNCTION OR BREAKDOWN, grounding provides the path of
least resistance for electric current and reduces the risk of electric shock. This tool is equipped with
an electric cord that has 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.
DO NOT MODIFY THE PLUG PROVIDED. If it will not fit the outlet, have the proper outlet
installed by an electrician.
IMPROPER CONNECTION of the equipment grounding conductor can result in electric shock.
The conductor with the green insulation (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 licensed electrician or service personnel if you do not completely understand the
grounding instructions, or if you are not sure if the tool is properly grounded.
Double insulated
This tool has a plug that looks like the one shown in Fig. A.
The tool is double insulated in order to provide a double thickness of insulation between you and
the tool’s electrical system. All exposed metal parts are isolated from the internal metal motor
components with protecting insulation.
WARNING: Double insulation does not take the place of normal safety precautions
when operating this tool.

Electrical information (continued)
Guidelines for using extension cords
WARNING: This tool is for indoor use only. Do not expose to rain or use in damp
locations.
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. The table below shows the correct size to
be used according to cord length and nameplate amperage rating. If in doubt, use the next heavier
gauge. The smaller the gauge number, the heavier the cord.
Minimum Gauge for Extension Cords (AWG)
(When using 120 V only)
Ampere Rating Total Length of Cord in feet
More Than Not More Than 25 feet 50 feet 100 feet 150 feet
0 6 18 gauge 16 gauge 16 gauge 14 gauge
Be sure your extension cord is properly wired and in good condition. Always replace a damaged
extension cord or have it repaired by a qualified person before using it.
Protect your extension cords from sharp objects, excessive heat and damp or wet areas.
Use a separate electrical circuit for your tools. This circuit must not be less than a #12 wire and
should be protected with a 15 A time-delayed fuse. Before connecting the motor to the power line,
make sure the switch is in the OFF position and the electric current is rated the same as the current
stamped on the motor nameplate. Running at a lower voltage will damage the motor.
WARNING: Although this tool is double insulated, the extension cord and receptacle
must still be grounded while in use in order to protect the operator from electric shock.
