GENERAL SAFETY RULES
WARNING!
READ AND UNDERSTAND ALL INSTRUCTIONS
Failure to follow all instructions listed below may result in
electric shock, re, and/or serious injury.
SAVE THESE INSTRUCTIONS
WORK AREA
Keep your work area clean and well lit. 1. Cluttered benches and dark areas invite
accidents.
Do not operate powered machines in explosive atmospheres, such as in the 2.
presence of ammable liquids, gases, or dust. Power machines create sparks
which may ignite the dust or fumes.

Keep bystanders, children, and visitors away while operating a powered ma-3.
chine. Distractions can cause you to lose control. Protect others in the work area
from debris fumes and oil. Provide barriers or shields as needed.
ELECTRICAL SAFETY
Grounded machines must be plugged into an outlet properly installed and 1.
grounded in accordance with all codes and ordinances. Never remove the
grounding prong or modify the plug in any way. Do not use any adapter plugs.
Check with a qualied electrician if you are in doubt as to whether the outlet is
properly grounded. If the machines should electrically malfunction or break down,
grounding provides a low resistance path to carry electricity away from the user.
Double insulated machines are equipped with a polarized plug (one blade is 2.
wider than the other). This plug will t in a polarized outlet only one way. If
the plug does not t fully in the outlet, reverse the plug. If it still does not
t, contact a qualied electrician to install a polarized outlet. Do not change
the plug in any way. Double insulation eliminates the need for the three wire
grounded power cord and grounded power supply system.
Avoid body contact with grounded surfaces such as pipes, radiators, ranges, 3.
and refrigerators. There is an increased risk of electric shock if your body is
grounded.
Do not expose powered machines to rain or wet conditions. 4. Water entering a
powered machine will increase the risk of electric shock.
Do not abuse the Power Cord. Never use the Power Cord to carry the machines 5.
or pull the Plug from an outlet. Keep the Power Cord away from heat, oil,
sharp edges, or moving parts. Replace damaged Power Cords immediately.
Damaged Power Cords increase the risk of electric shock.
When operating a powered machine outside, use an outdoor extension cord 6.
marked “W-A” or “W”. These extension cords are rated for outdoor use, and
reduce the risk of electric shock.
PERSONAL SAFETY
Stay alert. Watch what you are doing, and use common sense when operat-1.
ing a powered machine. Do not use a powered machine while tired or under
the inuence of drugs, alcohol, or medication. A moment of inattention while
operating powered machines may result in serious personal injury.
Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep 2.
your hair, clothing, and gloves away from moving parts in engine compartment.
Loose clothes, jewelry, or long hair can be caught in moving parts in the machine.

Page 4
Avoid accidental starting. Be sure the Power Switch is off before plugging in. 3.
Leaving the Power Switch on while the machine is unattended invites accidents.
Remove adjusting keys or wrenches before turning the powered machine on. 4.
A wrench or a key that is left attached to a rotating part of the powered machine
may result in personal injury.
Do not overreach. Keep proper footing and balance at all times. 5. Proper foot-
ing and balance enables better control of the powered machine in unexpected
situations.
Use safety equipment. Always wear eye protection. 6. Dust mask, nonskid safety
shoes, hard hat, or hearing protection must be used for appropriate conditions. Al-
ways wear ANSI-approved safety goggles and a dust mask/respirator when using
or performing maintenance on this machine. Keep the work area well ventilated.
TOOL USE AND CARE
Do not force the machine. Use the correct machine for your application. 1. The
correct machine will do the job better and safer at the rate for which it is designed.
Do not force the machine and do not use the machine for a purpose for which it is
not intended.
Do not use the powered machine if the Power Switch does not turn it on or 2.
off. Any machine that cannot be controlled with the Power Switch is dangerous
and must be replaced.
Disconnect the Power Cord Plug from the power source before making any 3.
adjustments, changing accessories, or storing the machine. Such preventive
safety measures reduce the risk of starting the machine accidentally. Always un-
plug the machine from its electrical outlet before performing any inspection,
maintenance, or cleaning procedures.
Store idle machines out of reach of children and other untrained persons. 4.
Tools are dangerous in the hands of untrained users.
Maintain machines with care. 5. Properly maintained machines are less likely to fail
and are easier to control. Do not use a damaged machine. Tag damaged machines
“Do not use” until repaired.
Check for misalignment or binding of moving parts, breakage of parts, and 6.
any other condition that may affect the machine’s operation. If damaged,
have the machine serviced before using. Many accidents are caused by poorly
maintained machines.
Use only accessories that are recommended by the manufacturer for your 7.
model. Accessories that may be suitable for one machine may become hazardous
when used on another machine.

GROUNDING
WARNING!
Improperly connecting the grounding wire can result in the risk of electric shock.
Check with a qualied 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 facil-
ity before use. If the plug will not t the outlet, have a proper outlet installed by
a qualied electrician.
GROUNDED TOOLS: TOOLS WITH THREE PRONG PLUGS
Tools marked with “Grounding Required” have a three wire cord and three prong 1.
grounding plug. The plug must be connected to a properly grounded outlet. If the
machine should electrically malfunction or break down, grounding provides a low
REV 08a
Page 6SKU 95951 For technical questions, please call 1-800-444-3353.
Page 7
resistance path to carry electricity away from the user, reducing the risk of electric
shock. (See 3-Prong Plug and Outlet.)
The grounding prong in the plug is connected through the green wire inside the 2.
cord to the grounding system in the machine. The green wire in the cord must be
the only wire connected to the machine’s grounding system and must never be at-
tached to an electrically “live” terminal. (See 3-Prong Plug and Outlet.)
Your machine must be plugged into an appropriate outlet, properly installed and 3.
grounded in accordance with all codes and ordinances. The plug and outlet should
look like those in the following illustration. (See 3-Prong Plug and Outlet.)
3-Prong Plug and Outlet Outlets for 2-Prong Plug
DOUBLE INSULATED TOOLS: TOOLS WITH TWO PRONG PLUGS
Tools marked “Double Insulated” do not require grounding. They have a special 1.
double insulation system which satises OSHA requirements and complies with the
applicable standards of Underwriters Laboratories, Inc., the Canadian Standard
Association, and the National Electrical Code. (See Outlets for 2-Prong Plug.)
Double insulated machines may be used in either of the 120 volt outlets shown in 2.
the preceding illustration. (See Outlets for 2-Prong Plug.)
EXTENSION CORDS
Grounded1. machines require a three wire extension cord. Double Insulated ma-
chines can use either a two or three wire extension cord.
As the distance from the supply outlet increases, you must use a heavier gauge 2.
extension cord. Using extension cords with inadequately sized wire causes a seri-
ous drop in voltage, resulting in loss of power and possible machine damage.
(See Table A.)
The smaller the gauge number of the wire, the greater the capacity of the cord. For 3.
example, a 14 gauge cord can carry a higher current than a 16 gauge cord.
(See Table A.)
When using more than one extension cord to make up the total length, make sure 4.
each cord contains at least the minimum wire size required. (See Table A.)
Page 7SKU 95951 For technical questions, please call 1-800-444-3353.
Page 8
If you are using one extension cord for more than one machine, add the nameplate5.
amperes and use the sum to determine the required minimum cord size.
(See Table A.)
If you are using an extension cord outdoors, make sure it is marked with the sufx 6.
“W-A” (“W” in Canada) to indicate it is acceptable for outdoor use.
Make sure your extension cord is properly wired and in good electrical condition. 7.
Always replace a damaged extension cord or have it repaired by a qualied electri-
cian before using it.
Protect your extension cords from sharp objects, excessive heat, and damp or wet 8.

OPERATION
Preparation
Before operation, check the Vacuum Pump oil level. Do this by looking through 1.
the opening on the lower right side of the back panel. You will be able to see the
vacuum pump oil reservoir. The level must be between the MIN and MAX mark-
ings. If the oil level is low, open the back of the machine, remove the cap of the oil
reservoir and ll to the MAX line with good quality compressor oil. Replace the oil
cap and back of machine before beginning operation. DO NOT OPERATE THIS
MACHINE WITHOUT ADEQUATE OIL IN THE VACUUM PUMP, SEVERE DAM-
AGE WILL RESULT.
WARNING: The A/C (air conditioning) system is under high pressure. Do not loosen 2.
any hose ttings or remove any components until after the system has been com-
pletely discharged and depressurized. Removal or loosening of a component while
the system is under pressure can cause severe personal and property damage or
injury.
Checking the Vehicle A/C System
Check the vehicle compressor drive belt. If it is worn or cracked, it should be re-1.
placed before any other service is performed.
Check the vehicle system hoses. Look for cracks, bubbles, hard spots and dete-2.
rioration. Inspect all hoses and ttings for leaks and refrigerant seepage. If there
is any evidence of wear, replace the damaged parts before performing any other
service.
Note: Use of a leak detector kit (not included) is recommended.
Inspect the compressor ns for debris that may be impeding heat dispersion of the 3.
compressor. Clean between the ns with a tool or compressed air.
Attaching the Recovery / Recharge Machine
Operate the vehicle A/C system on “High” for a few minutes to pressurize the sys-1.
tem. Turn the vehicle OFF. WARNING: Opening the HP valve while the vehicle
is running with the A/C system on can cause the refrigerant tank to break or
explode.

Relling the Automotive System with Oil and Refrigerant
Vehicle manufacturers design for and specify a specic amount of refrigerant for 1.
best operation of your vehicle A/C system. This amount is specied in weight. Too
much or too little refrigerant will adversely effect the operation of the A/C system.
Some newer vehicles will shut down the A/C system if too much refrigerant is in
the system.
After recovery, check the amount of used oil separated from the automotive sys-2.
tem, and be sure there is at least 20 ml more new oil in the New Oil bottle than the
amount removed. If there is not enough oil in the bottle, close the Oil Charge Valve
(I-9) and add oil to the new oil bottle.
Check to be sure the HP and LP valves on the Control Panel are open.3.
Slowly open the Oil Charge Valve (I-9) allowing new oil to be sucked into the au-4.
tomotive A/C system. Do not open the valve all the way, rather, use it carefully to
control the ow of oil. Allow oil to ow into the system until 10 ml more than the
amount removed has been added back.
When sufcient oil has owed back into system, close Oil Charge Valve.5.
Press the “Relling” Key on the Control Panel. The machine will begin to replace 6.
refrigerant in the vehicle A/C system. The Relling Indicator light will be on.
