gasses or liquids near heat sources of any kind. Do not operate power tools in close
proximity to the Oil Gun.

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

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. 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. There are certain applications for which this tool
was designed. It will do the job better and more safely at the rate for which it was
intended. Do not modify this tool and do not use this tool for a purpose for which it
was not intended.

6. 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.
Wear heavy work gloves during operation.

and if damaged, have them repaired by an authorized technician. The handle must be
kept clean, dry, and free from oil and grease at all times.

10. Disconnect hoses. Disconnect from fluid source when not in use.

11. Avoid unintentional starting. Do not carry any tool with your finger on the Handle
Lever whether it is attached to the fluid source or not.

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

13. 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.

14. 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.

labels if taking prescription medicine to determine if your judgment or reflexes are
impaired while taking drugs. If there is any doubt, do not operate the tool.
