General Power Tool Safety Warnings
_ ARNING! 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 tool or
battery-operated (cordless) power tool
1) WORK AREA SAFETY
a) Keep work area clean and well lit. Cluttered or dark areas invite accidents.
b) Do not 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.
c) Keep children and bystanders away while operating a power tool. Distractions can
cause you to lose control
2) ELECTRICAL SAFETY
a) Power tool plugs must match the outlet. Never modify the plug in any way. Do
not use any adapter plugs with earthed (grounded) power tools. Unmodified p/ugs
and matching outlets will reduce risk of electric shock.
b) Avoid body contact with earthed or grounded surfaces such as pipes, radiators,
ranges and refrigerators. There is an increased risk of electric shock if your body is
earthed or grounded.
c) Do not expose power tools to rain or wet conditions. Water entering a power tool
will increase the risk of electric shock.
d) Do not 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 increase the risk of electric shock.
e) When operating a power tool outdoors, use an extension cord suitable for
outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.
If operating a power tool in a damp location is unavoidable, use a ground fault
circuit interrupter (GFCI) protected supply. Use of a GFCI reduces the risk of electric
shock.
3) PERSONAL SAFETY
@ Stay alert, watch what you are doing and use common sense when operating a
power tool. Do not 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,
b) 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.
c) 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.
d) 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,
e) Do not overreach. Keep proper footing and balance at all times. This enables
better control of the power too/in unexpected situations.
Dress properly. Do not wear loose clothing or jewelry. Keep your hair, clothing
and gloves away from moving parts. Loose clothes, jewelry or long hair can be caught
in moving parts.
g) If devices are provided for the connection of dust extraction and collection
facilities, ensure these are connected and properly used. Use of dust collection
can reduce dust-related hazards.
4) POWER TOOL USE AND CARE
@ Do not force the power tool Use the correct power tool for your application. The
correct power tool wll/ do the job better and safer at the rate for which it was designed.
b) Do not use the power tool if the switch does not turn it on and off. Any power tool
that cannot be controlled with the switch is dangerous and must be repaired.
c) Disconnect the plug from the power source andlor 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,
d) Store idle power tools out of the reach of children and do not allow persons
unfamiliar with the power tool or these instructions to operate the power tool
Power tools are dangerous in the hands of untrained users.
e) Maintain power tools. 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 caused by poorly maintained power tools.
t) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp
cutting edges are less likely to bind and are easier to control.
g) Use the power tool, accessories and tool bits, etc. in accordance with these
instructions, 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.
5) SERVICE
@ Have your power tool serviced by a qualified repair person using only identical
replacement parts. This will ensure that the safety of the power tool is maintained.
Additional Safety Rules - Portable Band Saws
• Hold power tools by insulated gripping surfaces when performing an operation
where the cutting accessory may contact hidden wiring or its own cord. Cutting
accessory contacting a "live" wire may make exposed metal parts of the power tool "live"
and could give the operator an electric shock.
• Keep hands away from cutting area and blade. Keep one hand on the main handle and
the other hand on the front handle to prevent loss of control which could result in personal
injury,
• Always make sure the portable band saw is clean before using.
• Always cease operation at once If you notice any abnormality whatsoever.
• Always be sure all components are mounted properly and securely before using tool
• Always handle the band saw blade with care when mounting or removing it.
• Always keep your hands out of the line of the band saw blade.
• Always wait until the motor has reached full speed before starting a cut.
• Always keep handles dry, clean, and free of oil and grease. Hold the tool firmly when in use.
• Always be alert at all times, especially during repetitive, monotonous operations. Always be
sure of position of your hands relative to the blade.
• Never remove work stop.
• Stay clear of end pieces that may fall after cutting off. They may be hot, sharp and/or heavy,
Serious personal injury may result.
• Air vents often cover moving parts and should be avoided. Loose clothes, jewelry or
long hair can be caught in moving parts.
• An extension cord must have adequate wire size (AWG or American Wire Gauge)
for safety. The smaller the gauge number of the wire, the greater the capacity of the cable,
that is 16 gauge has more capacity than 18 gauge. An undersized cord wll/ cause a drop in
line voltage resulting in loss of power and overheating. When using more than one extension
to make up the total length, be sure each individual extension contains at least the minimum
wire size. The following table shows the correct size to use depending on cord length and
nameplate ampere rating. If in doubt, use the next heavier gauge. The smaller the gauge
number, the heavier the cord.
