6. Use the right tool for the job. Do not attempt to force a small tool or attachment to do
the work of a larger industrial tool. Do not use a tool for a purpose for which it was not
intended.
7. Dress properly. Do not wear loose clothing or jewelry as they can be caught in
moving parts. Protective, electrically non-conductive clothes and non-skid footwear
are recommended when working. Wear restrictive hair covering to contain long hair.
8. Use eye and ear protection. Always wear ANSI approved impact safety goggles.
Wear a full face shield if you are producing metal filings or wood chips. Wear an ANSI
approved dust mask or respirator when working around metal, wood, and chemical
dusts and mists. Wear ear protection when sanding for long periods.
9. Do not overreach. Keep proper footing and balance at all times. Do not reach over or
across running machines.
10. Maintain tools with care. Keep tools sharp and clean for better and safer
performance. Follow instructions for lubricating and changing accessories. Inspect tool
cords periodically and, if damaged, have them repaired by an authorized technician.
The handles must be kept clean, dry, and free from oil and grease at all times.
11. Disconnect power. Unplug when not in use.
12. Remove adjusting keys and wrenches. Check that keys and adjusting wrenches
are removed from the tool or machine work surface before plugging it in.
13. Avoid unintentional starting. Be sure the switch is in the Off position when not in use
and before plugging in.
14. Stay alert. Watch what you are doing, use common sense. Do not operate any tool
when you are tired.
15. Check for damaged parts. Before using any tool, any part that appears damaged
should be carefully checked to determine that it will operate properly and perform its
intended function. Check for alignment and binding of moving parts; any broken parts
or mounting fixtures; and any other condition that may affect proper operation. Any part
that is damaged should be properly repaired or replaced by a qualified technician. Do
not use the tool if any switch does not turn On and Off properly.
16. Guard against electric shock. Prevent body contact with grounded surfaces such as
pipes, radiators, ranges, and refrigerator enclosures.
17. Replacement parts and accessories. When servicing, use only identical
replacement parts. Use of any other parts will void the warranty. Only use accessories
intended for use with this tool. Approved accessories are available from Harbor Freight
Tools.
18. Do not operate tool if under the influence of alcohol or drugs. Read warning
labels on prescriptions to determine if your judgment or reflexes are impaired while
taking drugs. If there is any doubt, do not operate the tool.
19. Avoid causing fires. When sanding metals remove dust collecting bags and hoses
from the machine. Sparks or hot metal could start a fire. Clean all wood dust before
and after sanding metal.

Note: Performance of this tool may vary depending on variations in local
line voltage. Extension cord usage may also affect tool performance.
Warning: The warnings, cautions, 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.
Unpacking
When unpacking, check to make sure the tool is assembled and all parts present. Refer to
the Assembly Drawing at the end of this manual. If any parts are missing or broken, please
call Harbor Freight Tools at the number on the cover of this manual as soon as possible.
Using Extension Cords
When using extension cords, they must have a minimum wire size depending on the amperage of the tool and the length of the extension cord. This size is signified by its AWG rating;
the smaller the gauge, the greater the cable’s capacity. The extension cord must have a
grounding prong. For this Belt Sander, use an extension cord rated at 16 AWG for lengths up
to 50 feet.
