you to potential personal  
injury hazards. Obey all  
safety messages that follow  
this symbol to avoid possible  
injury or death.  
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.  
danger indicates a  
hazardous situation  
which, if not avoided, will result  
in death or serious injury.

away while operating a power tool.  
Distractions can cause you to lose  
control.

hazardous situation  
which, if not avoided, could  
result in death or serious injury.  
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 grounded power tools.  
Unmodified plugs and matching outlets  
will reduce risk of electric shock.

finger on the switch or energizing power  
tools that have the switch on invites  
accidents.  
c. do not expose power tools to rain  
or wet conditions. Water entering  
a power tool will increase the risk of  
electric shock.  
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.  
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. 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.  
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.

preventive safety measures reduce  
the risk of starting the power tool  
accidentally.  
Belt Sander Safety warnings  
1. hold power tools by insulated  
gripping surfaces when performing  
an operation where the cutting 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.  
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.  
2. Maintain labels and nameplates on  
the tool. These carry important safety  
information. If unreadable or missing,  
contact Harbor Freight Tools for a  
replacement.  
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.  
3. Avoid unintentional starting. Prepare to  
begin work before turning on the tool.  
4. Do not lay the tool down until it has come  
to a complete stop. Moving parts can  
grab the surface and pull the tool out of  
your control.  
5. When using a handheld power tool,  
maintain a firm grip on the tool with both  
hands to resist starting torque.  
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.  
6. Do not leave the tool unattended when  
it is plugged into an electrical outlet.  
Turn off the tool, and unplug it from its  
electrical outlet before leaving.  
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.  
7. This product is not a toy. Keep it out of  
reach of children.  
8. People with pacemakers should  
consult their physician(s) before use.  
Electromagnetic fields in close proximity  
to heart pacemaker could cause  
pacemaker interference or pacemaker  
failure. In addition, people with  
pacemakers should:  
5. 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 tool  
is maintained.  
• Avoid operating alone.  
• Do not use with Trigger locked on.  
• Properly maintain and inspect to avoid  
electrical shock.  
• Any power cord must be properly  
grounded. Ground Fault Circuit

other construction activities, contains  
chemicals known [to the State of

or for an extended period should first  
be examined by a doctor and then have

or other reproductive harm. Some  
examples of these chemicals are:  
• Lead from lead-based paints  
• Crystalline silica from bricks and  
cement or other masonry products  
• 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. (California Health  
& Safety Code § 25249.5, et seq.)  
should not use this tool. If you feel any  
symptoms related to vibration (such as  
tingling, numbness, and white or blue  
fingers), seek medical advice as soon as  
possible.  
2. Do not smoke during use. Nicotine  
reduces the blood supply to the hands  
and fingers, increasing the risk of  
vibration-related injury.  
3. Wear suitable gloves to reduce the  
vibration effects on the user.  
10. WARNING: Handling the cord on this  
product will expose you to lead, a  
chemical known to the State of California  
to cause cancer, and birth defects or  
other reproductive harm. Wash hands  
after handling. (California Health &  
Safety Code § 25249.5, et seq.)  
4. Use tools with the lowest vibration when  
there is a choice.  
5. Include vibration-free periods each day  
of work.  
6. Grip tool as lightly as possible (while still  
keeping safe control of it). Let the tool  
do the work.  
11. The warnings, precautions, and  
instructions discussed in this instruction  
manual cannot cover all possible  
conditions and situations that may occur.  
It must be understood by the operator  
that common sense and caution are  
factors which cannot be built into this  
product, but must be supplied by the  
operator.  
7. To reduce vibration, maintain the tool  
as explained in this manual. If any  
abnormal vibration occurs, stop use  
immediately.

4. When using more than one extension  
cord to make up the total length, make  
sure each cord contains at least the  
minimum wire size required. (See table

5. If you are using one extension cord for  
more than one tool, add the nameplate

6. If you are using an extension cord  
outdoors, make sure it is marked with the  
suffix “W-A” (“W” in Canada) to indicate it  
is acceptable for outdoor use.  
1. Tools marked “Double Insulated” do  
not require grounding. They have a  
special double insulation system which  
satisfies OSHA requirements and  
complies with the applicable standards  
of Underwriters Laboratories, Inc., the  
Canadian Standard Association, and the  
National Electrical Code. (See Outlets
