working in a dusty environment. Use ear protection, such as plugs or
muffs, during extended periods of operation.
Laser safety
1. Do not stare directly at the laser beam. Eye damage may
occur if you deliberately stare into the beam. Wear laser
enhancing glasses (not provided) when using the laser.
2. The laser light beam used in this system is Class III with ≤5
mW and 640–660 nm wavelengths. AVOID DIRECT EYE
EXPOSURE.
3. The laser must be used and maintained in accordance with
the manufacturer’s instructions:
• Never aim the beam at any person or an object other
than the workpiece.
• Do not project the laser beam into the eyes of others.
• Always ensure the laser beam is aimed at a workpiece
without reflective surfaces as the laser beam could be
projected into your eyes or the eyes of others.

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 person if you do not completely understand the
grounding instructions, or if you are not sure if the tool is properly grounded.
USE ONLY THREE-WIRE EXTENSION CORDS that have 3-pronged plugs and 3-pronged
outlets that accept the tool's plug as shown in Fig. A. Repair or replace a damaged or worn cord
immediately.
CAUTION: In all cases, make certain the outlet in question is properly grounded. If you are not
sure, have a licensed electrician check the outlet.

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 ampere 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 50 100 150
0 6 18 16 16 14
6 10 18 16 14 12
10 12 16 16 14 12
12 16 14 12 Not Recommended
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: This tool must be grounded while in use to protect the operator from electric
shock.
