USER MANUAL 3
.WORK AREA SAFETY
- Keep work area clean and well lit. Cluttered or dark areas lead to
accidents.
- 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.
- 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. Do not use any adapter plugs with earthed (grounded) power tools.
Unmodified plugs and matching outlets will reduce risk of electric shock.
- Avoid body contact with earthed or grounded surface such as pipes,
radiators, ranges and refrigerators. There is an increased risk of electric
shock if your body is earthed or grounded.
- Do not expose power tools to rain or wet conditions. Water entering a
power tool will increase the risk of electric shock.
- 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.
- 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.
.PERSONAL SAFETY
a- Stay alert, watch what you are doing and use common sense when
operation 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

BELT SANDER
4
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 tool in unexpected situations.
f- 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 facilitles, ensure these are connected and properly used. Use
of dust collection can reduce dust-related hazards.
.POWER TOOL USE AND CARE
a- Do not 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.
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 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.
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

USER MANUAL 5
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.
f- 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.
.SERVICE
a- Have your power tool serviced by a qualified repair person using only
identical replacement parts. This will ensure that the safety of the power
too is maintained.
Belt Sander Safety Warnings
- Hold power tool by Insulated gripping surfaces, because the belt may
contact its own cord. Cutting a “live” wire may make exposed metal parts
of the tool “live” and could give the operator an electric shock.
- Always use proper eye protection and a respirator when sanding.
- Use clamps or another practical way to secure and support the work
piece to a stable platform. Holding the work by hand or against your body
leaves it unstable and may lead to loss of control.
- Sanding of lead-based paint is not recommended. See Sanding Lead
Based Paint for additional information before sanding paint.
- Clean your tool out periodically.
WARNING!
Some dust created by power sanding, sawing, and grinding, drilling,
and other construction activities contains chemicals known to the State
of California to cause cancer, birth defects or other reproductive harm.
Some examples of these chemicals are:
- lead from lead-based paints,

BELT SANDER
6
- crystalline silica from bricks and cement and other masonry products, and
- arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how often you do
this type of work. To reduce your exposure to these chemicals: work in
a well ventilated area, and work with approved safety equipment, such
as those dust masks that are specially designed to filter out microscopic
particles.
Avoid prolonged contact with dust from power sanding, sawing,
grinding, drilling, and other construction activities. Wear protective
clothing and wash exposed areas with soap and water. Allowing dust to
get into your mouth, eyes, or lay on the skin may promote absorption of
harmful chemicals.
WARNING!
Use of this tool can generate and/or disperse dust, which may cause
serious and permanent respiratory or other Injury. Always use NIOSH/
OSHA approved respiratory protection appropriate for the dust exposure.
Direct particles away from face and body.
WARNING!
ALWAYS use safety glasses. Everyday eye glasses are NOT safety
glasses. Also use face or dust mask if cutting operation is dusty. ALWAYS
WEAR CERTIFIED SAFETY EQUIPMENT:
CAUTION !
Wear appropriate hearing protection during use. Under some conditions
and duration of use, noise from this product may contribute to hearing
loss.

OTHER IMPORTANT SAFETY WARNINGS AND INSTRUCTIONS
SANDING
LEAD BASE PAINT
Sanding of lead based paint is NOT RECOMMENDED due to the
difficulty of controlling the contaminated dust. The greatest danger of
lead poisoning is to children and pregnant Women.
Since it is difcult to identify whether or not paint contains lead without a
chemical analysis, we recommend the following precautions when sanding
any paint:
PERSONAL SAFETY
·No children or pregnant women should enter the work area where the
paint sanding is being done until all clean up is completed.
· A dust mask or respirator should be worn by all persons entering the
work area. The lter should be replaced daily or whenever the wearer
has difculty breathing.
NOTE:
Only those dust masks suitable for working with lead paint dust and fumes
should be used. Ordinary painting masks do not offer this protection. See
your local hardware dealer for the proper (NIOSH approved) mask.
- NO EATING, DRINKING or SMOKING should be done in the work
area to prevent ingesting contaminated paint particles. Workers should
wash and clean up BEFORE eating, drinking or smoking. Articles of
food, drink, or smoking should not be left in the work area where dust
would settle on them.
ENVIRONMENTAL SAFETY
- Paint should be removed in such a manner as to minimize the amount
of dust generated.

BELT SANDER
8
- Areas where paint removal is occurring should be sealed with plastic
sheeting of 4 milsthickness.
- Sanding should be done in a manner to reduce tracking of paint dust
outside the work area.
CLEANING AND DISPOSAL
- All surfaces in the work area should be vacuumed and thoroughly
cleaned daily for the duration of the sanding project. Vacuum lter bags
should be changed frequently.
- Plastic drop cloths should be gathered up and disposed of along with
any dust chips or other removal debris. They should be placed in
sealed refuse receptacles and disposed of through regular trash pick-up
procedures. During clean up, children and pregnant women should
be kept away from the immediate work area.
- All toys, washable furniture and utensils used by children should be
washed thoroughly before being used again.
MOTOR
Be sure your power supply matches with nameplate marking. This
information is printed on the nameplate. Lower voltage will cause loss of
power and can result in over-heating. All tools are factory-tested; if this
tool does not operate, check the power supply.
