8. USE EYE PROTECTION. Solvents can cause serious eye damage . Wear ANSI approved  
chemical splash safety goggles. Goggles are available from Harbor Freight Tools. When  
cleaning, be especially careful as solvents can be forcibly ejected from fluid and air  
passages.  
9. DRESS SAFELY. Protective gloves and nonskid footwear or safety shoes must be used  
when working with and operating the Parts Washer. Don’t wear loose clothing or jewelry.  
They can get caught in moving parts. Also, wear a protective hair covering to prevent long  
hair from getting caught in the Parts Washer.  
10. DON’T OVERREACH. Keep proper footing and balance at all times.  
11. STAY ALERT. Watch what you are doing. Use common sense. Do not operate any tool  
when you are tired.  
12. CHECK DAMAGED PARTS. Before using any tool, any part that is damaged should be  
carefully checked to determine that it will operate properly and perform its intended function.  
Check for alignment of moving parts, breakage of parts, and other conditions that may  
affect its operation.  
13. REPLACEMENT PARTS AND ACCESSORIES. When servicing, use only identical  
replacement parts. Only use accessories intended for use with this Parts Washer.  
Approved accessories are available from Harbor Freight Tools.  
14. STORE IDLE EQUIPMENT. When not in use, the Parts Washer should be cleaned and  
then stored, fully assembled, in a dry location to reduce rust. For safety, keep out of reach  
of children.  
15. MAINTAIN TOOLS WITH CARE. Keep tools clean for better and safer performance.  
Follow instructions for lubricating, cleaning and changing accessories. Keep handles dry,  
clean and free from oil and grease.  
16. OUTDOOR EXTENSION CORDS. When the Parts Washer is used outdoors, use only  
rounded jacket extensions cords intended for outside use. See manufacturer’s manual for  
the AWG required for the compressor’s amperage draw. Do not leave the Parts Washer  
outside for extended periods of time.  
17. DO NOT MODIFY OR JAM LID TO KEEP LOCKED IN AN OPEN POSITION. The lid is  
on a fusible link and is designed to fall automatically to extinguish flames. If fire should  
occur, do not attempt to move parts washer.  
GROUNDING INSTRUCTIONS  
1. This machine has a three prong plug. The third prong (round) is the ground. Plug the  
machine’s cord only into three-prong receptacles. Never cut off the round prong. Cutting off  
the ground will result in a safety hazard and void the warranty.  
2. If a three-prong receptacle is not available, you may use an adapter. Extending from the  
male end of the adapter, you will find a ring connector or wire lead with a ring connector  
where the ground (round prong) would be. Remove the center screw of the outlet cover and  
put the screw through the ring connector and back into the hole of the outlet cover. Do not  
over tighten or you will crack the outlet cover.

VOLTAGE WARNING  
Common household current is 110-120 volts. As long as your tool is rated from 110V-120V there  
will be no complications using this tool with household receptacles. If your tool is rated 220V-240V  
it has a completely different style of plug and must be used with a 220V-240V receptacle. Never try  
to plug a 110V-120V tool into a 220V-240V circuit (or vice-versa) or serious complications will  
arise, including possible injury to the operator. The plugs and receptacle have completely different  
shapes to prevent this from occurring accidentally. Do not modify your plug in any way. If you have  
any doubts, call a qualified electrician.  
EXTENSION CORDS  
Your tool has a three prong plug, therefore you must use a three- prong extension cord. Only use  
rounded jacket extension cords listed by the Underwriters Laboratories (UL). If you are using the  
tool outdoors, you must use an extension cord rated for outdoor use. This is signified by the letters  
“WA” on the jacket.  
The extension cord 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 (American Wire Gauge) rating.  
The smaller the gauge, the greater the cable’s capacity. It does not matter if you are using one  
cord, or two or more- the total length is what is used to determine the minimum AWG rating. Every  
cord used must meet the AWG rating. Use the chart below to determine what AWG rating is  
required for your situation. Cord length is rated in feet.

Always inspect extension cords for any damage. If there are any loose, frayed, or exposed wires;  
damaged insulation; or defective connections, the cord must not be used. Harbor Freight Tools  
can supply UL listed and outdoor rated cords in multiple AWG rating if needed.
