PERSONAL SAFETY
1. Dress properly, wear protective equipment. Use breathing, ear, eye, face, foot, hand and head protection.
Always wear ANSI approved impact safety goggles, which must provide both frontal and side protection.
Protect your hands with suitable gloves. Wear a full face shield if your work creates metal filings or wood
chips. Protect your head from falling objects by wearing a hard hat. Wear an ANSI approved dust mask or
respirator when working around metal, wood and chemical dusts and mists. Wear ANSI approved earplugs.
Protective, electrically non-conductive clothes and non-skid footwear are recommended when working. Wear
steel toed boots to prevent injury from falling objects.
2. Do not over reach; keep proper footing and balance at all times. Proper footing and balance enables better
control of the tool in unexpected situations.
3. Keep any articles of clothing, jewelry, hair etc. away from moving parts. These can be caught in moving
parts, resulting in damage to the tool and/or serious injury.
4. Stay alert, watch what you are doing and use your common sense. Do not operate any machine or tool when
you are tired, under the influence of drugs, alcohol or medications.
5. Use clamps or other practical ways to secure and support the work piece to a stable platform. Holding the
work piece by hand or against your body is unstable and may lead to loss of control.
6. Prevent unintentional starting. Ensure the switch is in the off-position before connecting to power source
and/or battery pack, picking up or carrying the tool. Carrying power tools with your finger on the switch or
energising power tools that have the switch on invites accidents.
ELECTRICAL SAFETY
1. Disconnect power supply. Disconnect from power supply when not in use, before cleaning, servicing or
changing any parts or accessories.
2. Protect yourself against electric shocks when working on electrical equipment. Avoid body contact with
grounded surfaces such as pipes, radiators, cooking stoves and refrigerators. There is an increased chance
of electrical shock if your body is grounded.
3. Use caution when performing an operation where the fastener may contact hidden wiring or its own cord.
Fasteners contacting a “live” wire may make exposed metal parts of the power tool “live” and could give the
operator an electrical shock.
4. Double insulated tools are equipped with a polarized plug (one blade is wider than the other). This plug will
fit in a polarized outlet only one way. If the plug does not fit fully in the outlet, reverse the plug. If it still does
not fit, contact a qualified electrician to install a polarized outlet. Do not change the plug in any way. Double
insulation eliminates the need for a three wire grounded power cord and grounded power supply system.
5. Grounded tools must be plugged into an outlet properly installed and grounded in accordance with all codes
and ordinances. Never remove the grounding prong or modify the plug in any way. Do not use any adapter
plugs. Check with a qualified electrician if you are in doubt as to whether the outlet is properly grounded. If
the tool should electronically malfunction or break down, grounding provides a low resistance path to carry
electricity away from the user.
6. Do not abuse the cord. Never use the cord to carry the tools or pull the plug from an outlet. Keep cord away
from heat, oil, sharp edges or moving parts. Do not operate this tool if the power cord is frayed or damaged.
Replace damaged cords immediately. Damaged cords increase the risk of electric shock. Do not modify the
plug in any way.
7. 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 electric shock. Use in conjunction with a Ground Fault Circuit
Interrupter (GFCI). If operating a power tool in a damp location is unavoidable, the use of a GFCI reduces the
risk of electric shock. It is recommended that the GFCI should have a rated residual current of 30 mA or less.
8. Avoid using an unnecessarily long extension cord. Choose a cord that is appropriate for the situation, as a
cord that is too long and running across the floor can be more dangerous than helpful. Using a cord that is
too long or too thin could damage the tool. Unroll the cord completely to prevent it from overheating.
9. Place the electrical cord in a position that prevents it from coming into contact with the tool and from getting
caught by the work piece. The cord should always stay behind the tool.
