IMPORTANT SAFETY INFORMATION

General Power Tool Safety Warnings

Read all safety warnings and instructions.

Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury.

Save all warnings and instructions for future reference.

The term ″power tool″ in the warnings refers to your mains-operated (corded) power tool.

Work area safety

1. Keep work area clean and well lit.

Cluttered or dark areas invite accidents.

2. Do not operate power tools in explosive

atmospheres, such as in the presence of

flammable liquids, gases or dust.

Power tools create sparks which

may ignite the dust or fumes.

3. Keep children and bystanders

away while operating a power tool.

Distractions can cause you to lose control.

4. NEVER use this Vacuum Pump to vent

refrigerants into the air. It is illegal and

harmful to the environment to do so.

SAFETYOPERATIONMAINTENANCE SETUP

Electrical safety

1. Power tool plugs must match the outlet.

Never modify the plug in any way.

Do not use any adapter plugs

with grounded power tools.

Unmodified plugs and matching outlets

will reduce risk of electric shock.

2. Do not expose power tools to rain or

wet conditions. Water entering a power

tool will increase the risk of electric shock.

3. Do not abuse the cord. Never use the

cord for carrying, pulling or unplugging

the power tool. Keep cord away from

heat, oil, sharp edges or moving parts.

Damaged or entangled cords increase

the risk of electric shock.

4. When operating a power tool outdoors,

use an extension cord

suitable for outdoor use.

Use of a cord suitable for outdoor use

reduces the risk of electric shock.

5. If operating a power tool in a damp

location is unavoidable, use a Ground

Fault Circuit Interrupter (GFCI)

protected supply. Use of a GFCI

reduces the risk of electric shock.

Personal safety

1. Stay alert, watch what you are

doing and use common sense when

operating a power tool. Do not use

a power tool while you are tired or

under the influence of drugs, alcohol

or medication. A moment of inattention

while operating power tools may

result in serious personal injury.

2. Use personal protective equipment.

Always wear eye protection.

Safetyequipment such as dust mask,

non-skid safety shoes, hard hat, or

hearing protection used for appropriate

conditions will reduce personal injuries.

3. Only use safety equipment

that has been approved by an

appropriate standards agency.

Unapproved safety equipment may

not provide adequate protection.

Eye protection must be ANSI-approved

and breathing protection must be

NIOSH-approved for the specific

hazards in the work area.

Power tool use and care

1. Use the correct power tool for your

application. The correct power tool

will do the job better and safer at the

rate for which it was designed.

2. Do not use the power tool if the Switch

does not turn it on and off.

Any power tool that cannot be

controlled with the Switch is

dangerous and must be repaired.

3. Disconnect the plug from the power

source before making any adjustments,

changing accessories, or storing

power tools.Such preventive safety

measures reduce the risk of starting

the power tool accidentally.

4. Store idle power tools out of the

reach of children and do not allow

persons unfamiliar with the power tool

or these instructions to operate the

power tool. Power tools are dangerous

in the hands of untrained users.

Page4 For technical questions, please call 1-800-444-3353. Item61176

SAFETY OPERATION MAINTENANCESETUP

5. Maintain power tools. Check for

misalignment or binding of moving

parts, breakage of parts and any other

condition that may affect the power tool’s

operation. If damaged, have the power

tool repaired before use. Many accidents

are caused by poorly maintained power tools.

6. Use the power tool, accessories and

tool bits etc. in accordance with these

instructions, taking into account the

working conditions and the work to

be performed. Use of the power tool for

operations different from those intended

could result in a hazardous situation.

Service

Have your power tool serviced by a qualified repair person using only identical

replacement parts. This will ensure that the safety of the power tool is maintained.

SAFETYOPERATIONMAINTENANCE SETUP

Grounding

TO PREVENT ELECTRIC SHOCK AND DEATH

FROM INCORRECT GROUNDING WIRE CONNECTION:

Check with a qualified electrician if you are in doubt as to whether the outlet is

properly grounded. Do not modify the power cord plug provided with the tool.

Never remove the grounding prong from the plug. Do not use the tool if the power cord or

plug is damaged. If damaged, have it repaired by a service facility before use. If the plug will

not fit the outlet, have a proper outlet installed by a qualified electrician.

General Operating Instructions

TO PREVENT SERIOUS INJURY AND DEATH FROM EXPLOSION:

Service of air conditioning systems must be done only by trained

and experienced technician to avoid overfilling.

Technicians opening refrigeration circuit in automotive air conditioning systems MUST be

certified in refrigerant recovery and recycling procedures in compliance with section 609 of

Clean Air Act Amendments of 1990. For additional information regarding ozone depletion

and air conditioning service regulations, visit EPA’s website: www.epa.gov/ozone
