Know your power tool.

 Read operator’s manual 

carefully. Learn its applications and limitations, as well 
as the specific potential hazards related to this tool. 
Following this rule will reduce the risk of electric shock, 
fire, or serious injury.

 

Drain tank of moisture after each day’s use.

 

If unit will not be used for a while, it is best to leave drain 
valve open until such time as it is to be used. This will 
allow moisture to completely drain out and help prevent 
corrosion on the inside of tank.

 

Risk of Fire or Explosion.

 Do not spray flammable 

liquid in a confined area. Spray area must be well 
ventilated. Do not smoke while spraying or spray where 
spark or flame is present. Keep compressors as far from 
the spraying area as possible, at least 15 feet from the 
spraying area and all explosive vapors.

 

Risk of Bursting.

 Do not adjust regulator to result 

in output pressure greater than marked maximum 
pressure of attachment. Do not use at pressure greater 
than the rated maximum pressure of this compressor.

 

If connected to a circuit protected by fuses,

 use 

time-delay fuses with this product.

 

To reduce the risk of electric shock,

 do not expose to 

rain. Store indoors.

 

Inspect tank yearly for rust, pin holes, or other 
imperfections that could cause it to become unsafe.

 

Never weld or drill holes in the air tank.

 

Make sure the hose is free of obstructions or snags.

 

Entangled or snarled hoses can cause loss of balance 
or footing and may become damaged.

 

Use the air compressor only for its intended use. Do 
not alter or modify the unit from the original design 
or function.

 

Always be aware that misuse and improper handling 
of this tool can cause injury to yourself and others.

 

Never leave a tool unattended with the air hose 
attached.

 

Do not operate this tool if it does not contain a 
legible warning label.

 

Do not continue to use a tool or hose that leaks air 
or does not function properly.

 

Always disconnect the air supply and power supply

 

before making adjustments, servicing a tool, or when a 
tool is not in use.

 

Do not attempt to pull or carry the air compressor 
by the hose.

 

Your tool may require more air consumption than 
this air compressor is capable of providing.

 

Never use the compressor without guards (belt 
guard) and never touch moving parts.

SPECIFIC SAFETY RULES

 

Always follow all safety rules recommended by the 
manufacturer of your tool, in addition to all safety 
rules for the air compressor. 

Following this rule will 

reduce the risk of serious personal injury.

 

Never direct a jet of compressed air toward people 
or animals. Take care not to blow dust and dirt 
towards yourself or others.

 Following this rule will 

reduce the risk of serious injury.

 

Protect your lungs.

 Wear a face or dust mask if the 

operation is dusty. Following this rule will reduce the 
risk of serious personal injury.

 

Do not use this air compressor to spray chemicals.

 

Your lungs can be damaged by inhaling toxic fumes. A 
respirator may be necessary in dusty environments or 
when spraying paint. Do not carry while painting.

 

Inspect tool cords and hoses periodically and, if 
damaged, have repaired at your nearest Authorized 
Service Center. Constantly stay aware of cord 
location.

 Following this rule will reduce the risk of 

electric shock or fire.

 

Never use an electrical adaptor with this grounded 
plug.

 

Check damaged parts. Before further use of the 
air compressor or air tool, a guard or other 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, binding of moving parts, breakage of 
parts, mounting, and any other conditions that may 
affect its operation. A guard or other part that is 
damaged should be properly repaired or replaced 
by an authorized service center.

 Following this rule 

will reduce the risk of shock, fire or serious injury.

 

Make sure your extension cord is in good 
condition. When using an extension cord, be sure 
to use one heavy enough to carry the current your 
product will draw. A wire gauge size (A.W.G.) of at 
least 14 is recommended for an extension cord 50 
feet or less in length. A cord exceeding 100 feet is 
not recommended. If in doubt, use the next heavier 
gauge. The smaller the gauge number, the heavier 
the cord.

 An undersized cord will cause a drop in line 

voltage resulting in loss of power and overheating.

 

Save these instructions.

 Refer to them frequently 

and use them to instruct others who may use this air 
compressor. If you loan someone this tool, load them 
these instructions also.
