SPECIFIC SAFETY PRECAUTIONS

WARNING! DO NOT let comfort or familiarity with the product (gained from repeated use) replace strict adherence to the tool safety rules. If you use this tool unsafely or incorrectly, you can suffer serious personal injury.

Use the correct tool for the job. This tool was designed for a specific function. Do not modify or alter this tool or use it for an unintended purpose.
Do not use the tool if any parts are damaged broken or misplaced. Repair or replace the parts.
Only use accessories that are specifically designed for use with the tool, and always ensure the accessory is tightly installed.
a. Do not use any accessories before reading their user manual.
b. Always follow all instructions that accompany any accessories.
Only use an accessory that exceeds the Speed Rating (see Specifications).
Before using the tool on a workpiece, test the tool by running it at the highest Speed Rating for at least 30 seconds in a safe position. Stop immediately if there is any abnormal vibration or wobbling. Check the tool to determine the cause.
a. Running the tool without load will shorten its life.
Never touch the tool accessory or workpiece during or immediately after use. They may be hot and could inflict a bum injury.
Examine the tool thoroughly before operating.
a. Check for alignment and binding of moving parts.
b. Look for any breakage of any parts or components.

ELECTRICAL SAFETY
WARNING! This tool must be grounded while in use to protect against electrical shock.

Disconnect the tool from the power supply before making any adjustments, changing accessories, cleaning, servicing, or when storing. Such preventive safety measures reduce the risk of starting the tool accidentally.
Use separate electrical circuits for your tools.
Do not expose the tool to rain, snow, frost, or any other damp or wet conditions. Water entering a tool will increase the risk of electric shock.
Do not disconnect the power cord in place of using the power switch. This will prevent accidental start-up when the power cord is plugged into the power supply.
a. In the event of a power failure, unplug the machine as soon as the power is interrupted. The possibility of accidental injury could occur if the power returns.
Do not alter any parts of the tool or accessories. All parts and accessories are designed with built-in safety features that may be compromised if they are altered.
Make certain the power source meets the requirements of your equipment.
This tool is only for use on 120V (single phase) and is equipped with a three-prong grounded power supply cord and plug (Fig. 1). Check with a qualified electrician if you’re in doubt as to whether the outlet is properly grounded. if the tool electronically malfunctions or breaks down, grounding provides a low resistance path to carry electricity away from the user. a. Never remove the grounding prong or modify the plug in any way, as this will render the tool unsafe.
b. Do not use adapter plugs.
c. If the provided plug will not fit the receptacle, have the proper receptacle installed by a qualified electrician.
Improper connection of the equipment grounding conductor can result in a risk of 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 the live terminal.
a. Note that there is an overcurrent protection device in the circuit. (Fig.

When using an extension cord, ensure it is heavy enough to carry the current required for the tool. Undersized cords will result in a drop in line voltage and power that will cause overheating. a. Be sure your extension cord is properly wired and in good condition.
b. Protect your extension cords from sharp objects, excessive heat, and damp or wet areas.
c. Always replace a damaged extension cord or have it repaired by a qualified person before using it.
