9. Do not overreach. Keep proper footing and balance at all times. Do not reach over or

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.
