AND sAFetY ruLes

• Keep bystanders, children, and visitors away 

while operating the OEMTools A/C Vacuum Pump. 

Distractions can cause you to lose control. Protect 

others in the work area from injury.

• Stay alert.  Watch what you are doing, and use 

common sense when operating the OEMTools A/C 

Vacuum Pump. Do not use the tool while tired or 

under the influence of drugs, alcohol, or medication. 

A moment of inattention while operating the tool may 

result in serious personal injury.

• Do not overreach. Keep proper footing and balance 

at all times. Proper footing and balance enables 

better control of the power tool in unexpected 

situations.

• Use safety equipment.
• Wear ANSI-approved safety glasses underneath 

a full face safety shield. Nonskid safety shoes, 

hard hat, or hearing protection must be used for 

appropriate conditions.

• Do not force the tool. Use the correct tool for your 

application. The correct tool will do the job better 

and safer at the rate for which it is designed.

• Store idle tools out of reach of children and other 

untrained persons. Tools are dangerous in the hands 

of untrained users.

• Maintain tools with care.
• Keep tools dry and clean.
• Properly maintained tools are less likely to bind and 

are easier to control.  Do not use a damaged tool. 

Tag damaged tools “Do not use” until repaired.

• Check for misalignment or binding of moving parts, 

breakage of parts, and any other condition that may 

affect the tool’s operation.

• If damaged, have the tool serviced before using. 

Many accidents are caused by poorly maintained 

tools.

• Use only accessories that are recommended by the 

manufacturer for your model. Accessories that may 

be suitable for one tool may become hazardous 

when used on another tool.

• Tool service must be performed only by qualified 

repair personnel. Service or maintenance performed 

by unqualified personnel could result in a risk of 

injury.

• When servicing a tool, use only identical replacement 

parts. Use of unauthorized parts or failure to follow 

maintenance instructions may create a risk of injury.

• Maintain a safe working environment. Keep the 

work area well lit. Make sure there is adequate 

surrounding workspace.  Keep the work area free of 

obstructions, grease, oil, trash, and other debris.  Do 

not use this product in a damp or wet location.

• Maintain labels and nameplates on this product. 

These carry important information.  If unreadable or 

missing, contact OEMTools for a replacement.

• Keep the handle dry, clean, and free from brake fluid, 

oil, and grease.

• Before use, read and understand all warnings, safety 

precautions, and instructions as outlined in the 

vehicle manufacturer’s service manual. It is beyond 

the scope of this manual to properly describe the 

correct procedure and test data for each vehicle.

• To reduce the risk of discomfort, illness, or death, 

read, understand, and follow the following safety 

instructions. Avoid breathing A/C refrigerant and 

lubricant vapor mist. Exposure may irritate eyes, 

nose, and throat. To remove R134a from the A/C 

system, use service equipment certified to meet 

the requirements of SAE J2788--R134a recycling 

equipment. Additional health and safety information 

may be obtained from refrigerant and lubricant 

manufacturers.
