GENERAL POWER TOOL SAFETY WARNINGS
WARNING!
- Read all safety warnings and all instructions. Failure to follow the warnings
and instructions may result in electric shock, fire and or serious injury.
- Save all warnings and instructions for future reference.
- The term “power tool” in the warnings refers to your mains-operated
(corded) power tools or battery operated (Cordless) Power tools.
.WORK AREA SAFETY
- Keep work area clean and well lit. Cluttered or dark areas invite accidents.
- Don’t operate power tools in explosive atmospheres, such as in the
presence of flammable liquids, gases or dust. Power tools create sparks
which may ignite the dust or fumes.
- Keep children and bystanders away while operating a power tool.

Distractions can cause you to lose control.
.ELECTRIC SAFETY
- Power tool plugs must match the outlet. Never modify the plug in any
way. Don’t use any adaptor plugs with earthed (grounded) power tools.
Unmodified plugs and matching outlets will reduce risk of electric shock.
- Avoid body contact with earthed or grounded surfaces such as pipe,
radiators, ranges and refrigerators. There is an increased risk of electric
shock if your body is earthed or grounded.
- Don’t expose power tools to rain or wet conditions. Water entering a
power tool will increase the risk of electric shock.
- Don’t abuse the cord. Never use the cord for carrying, pulling or
unplugging the power tool. Keep cord away from heat, oil, sharp edges
or moving parts. Damaged or entangled cords increased the risk of
electric shock.
- When operating a power tool outdoors, use an extension cord suitable
for outdoor use. Using a cord suitable for outdoor use will reduce the risk
of electric shock.
- If operating a power tool in a damp location is unavoidable, use a
residual current device (RCD) protected supply. Use of an RCD reduces
the risk of electric shock.
- Use of power supply via a RCD with a rated residual current of 30mA
or less is always recommended.
.PERSONAL SAFETY
- Stay alert, watch what you are doing and use common sense when
operating a power tool. Don’t use a power tool while you are tired
or under the influence of drugs, alcohol or medication. A moment of
inattention while operating power tools may result in serious personal injury.
- Use personal protective equipment. Always wear eye protection.
Protective equipment such as dust mask, non-skid safety shoes, hard
hat, or hearing protection used for appropriate conditions will reduce
personal injuries.

- 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
energizing power tools that have the switch on invites accidents.
- Remove any adjusting key or wrench before turning the power tool on.
A wrench or a key left attached to a rotating part of the power tool may
result in personal injury.
- Don’t overreach. Keep proper footing and balance at all times. This
enables better control of the power tool in unexpected situations.
- Dress properly. Don’t wear loose clothing or jewelry. Keep your hair,
clothing, and gloves away from moving parts. Loose cloths, jewelry or
long hair can be caught in moving parts.
- If devices are provided for connection of dust extraction and collection
facilities, ensure these are connected and properly used. Use of dust
collection can reduce dust-related hazards.
POWER TOOL USE AND CARE
- Don’t force the power tool. Use the correct power tool for your
application. The correct power tool will do the job better and safer at the
rate for which it was designed.
- Don’t use the power tool if the switch doesn’t turn it on and off. Any
power tool that cannot be controlled with the switch is dangerous and
must be repaired.
- Disconnect the plug from the power source and/or the battery pack from
the power tool before making any adjustments, changing accessories,
or storing power tools. Such preventive safety measures reduce the risk
of starting the power tool accidentally.
- Store idle power tools out of the reach of children and don’t allow
persons unfamiliar with power tool or these instructions to operate the
power tool. Power tools are dangerous in the hands of untrained users.
- Check for misalignment or binding of moving parts, breakage of parts
and any other condition that may affect the power tool’s operation. If
damaged, have the power tool repaired before use. Many accidents are

USER MANUAL 5
caused by poorly maintained power tools.
- Keep cutting tools sharp and clean. Properly maintained cutting tools
with sharp cutting edges are less likely to bind and are easier to control.
- Use the power tool, accessories and tool bits etc. in accordance with
the instruction, taking into account the working conditions and the work
to be performed. Use of the power tool for operations different from
those intended could result in a hazardous situation.
SERVICE
- Have your power tool serviced by qualified repair person using only
identical replacement parts. This will ensure that the safety of power tool
is maintained.
- Follow instruction for lubricating and changing accessories.
- Keep handles dry, clean and free from oil and grease.
SPECIFIC SAFETY RULES
- Always use proper guard with grinding wheel. A guard protects operator
from broken wheel fragments.
- Accessories must be rated for at least the speed recommended on the
tool warning label. Wheels and other accessories running over rated
speed can fly apart and cause injury.
- Hold tool by insulated gripping surfaces when performing an operation where
the grinding tool may contact hidden wiring or its own cord. Contact with a “live”
wire will make exposed metal parts of the tool “live” and shock the operator.
- When using depressed center grinding wheels, be sure to use only
fiberglass-reinforced wheels.
- Always use safety glasses or goggles. Ordinary eye or sun glasses are
NOT safety glasses.
- Check the wheel carefully for cracks or damage before operation.
Replace cracked or damaged wheel immediately. Run the tool (with
guard) at no load for about a minute, holding tool away from others. If
wheel is flawed, it will likely separate during this test.

- Use only flanges specified for this tool.
- Be careful not to damage the spindle, the flange (especially installing surface)
and the lock nut. Damage to these parts could result in wheel breakage.
- NEVER use tool with wood cutting blades or other saw blades. Such
blades when used on a grinder frequently kick and cause loss of control
leading to personal injury.
- Hold the tool firmly.
- Keep hands away from rotating parts.
- Make sure cord is clear of wheel. Do not wrap cord around your arm
or wrist. If control of tool is lost, cord may become wrapped around you
and cause personal injury.
- Make sure the wheel is not contacting the work piece before the switch
is turned on.
- Before using the tool on an actual workpiece, let it run for a while.
Watch for vibration or wobbling that could indicate poor installation or a
poorly balanced wheel.
- Use the specified surface of the wheel to perform the grinding.
- Watch out for flying sparks. Hold the tool so that sparks fly away from
you and other persons or flammable materials.
- Do not leave the tool running. Operate the tool only when hand-held.
- Do not touch the work piece immediately after operation; it may be
extremely hot and could burn your skin.
- ALWAYS wear proper apparel including long sleeve shirts, leather
gloves and shop aprons to protect skin from contact with hot grindings.
- Use of this tool to grind or sand some products, paints and wood could
expose user to dust containing hazardous substances. Use appropriate
respiratory protection.
WARNING!
MISUSE or failure to follow the safety rules stated in this instruction
manual may cause serious personal injury.
