Safety Warnings and Precautions

WARNING: When using tool, basic safety precautions should always be followed to
reduce the risk of personal injury and damage to equipment.

Read all instructions before using this tool!

1. Keep work area clean. Cluttered areas invite injuries.

2. Observe work area conditions. Do not use machines or power tools in damp or wet

locations. Don’t expose to rain. Keep work area well lighted. Do not use electrically
powered tools in the presence of flammable gases or liquids.

3. Keep children away. Children must never be allowed in the work area. Do not let

them handle machines, tools, or extension cords.

4. Store idle equipment. When not in use, tools must be stored in a dry location to

inhibit rust. Always lock up tools and keep out of reach of children.

5. Do not force tool. It will do the job better and more safely at the rate for which it was

intended. Do not use inappropriate attachments in an attempt to exceed the tool capacity.

6. Use the right tool for the job. Do not attempt to force a small Tumbler to do the work

of a larger industrial Tumbler. There are certain applications for which this Tumbler was
designed. Do not modify this Tumbler and do not use this Tumbler 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 nonconductive clothes and nonskid footwear are
recommended when working. Wear restrictive hair covering to contain long hair.

8. Use eye, ear, and face 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.

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 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.

11. Disconnect power. Unplug Tumbler when not in use.

12. Avoid unintentional starting. Be sure the switch is in the Off position when not in use

and before plugging in.

13. Stay alert. Watch what you are doing, use common sense. Do not operate any tool

when you are tired.

14. 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.

15. Guard against electric shock. Prevent body contact with grounded surfaces such as

pipes, radiators, ranges, and refrigerator enclosures.

16. 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.

17. 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.

18. Use proper size and type extension cord. If an extension cord is required, it must be

of the proper size and type to supply the correct current to the tool without heating up.
Otherwise, the extension cord could melt and catch fire, or cause electrical damage to
the tool. This tool requires use of an extension cord of 0 to 10 amps capability (up to 50
feet), with wire size rated at 18 AWG. Longer extension cords require larger size wire.
If you are using the tool outdoors, use an extension cord rated for outdoor use (signified
by “WA” on the jacket).

19. Maintenance. For your safety, maintenance should be performed regularly by a qualified

technician.

Note: Performance of this tool (if powered by line voltage) 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.
