keep bystanders, children, and visitors away while operating a powered ma-
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
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 qualified 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
wider than the other). This plug will fit in a polarized outlet only one way. If
the plug does not fit fully in the outlet, reverse the plug. If it still does not
fit, contact a qualified 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,
and refrigerators. There is an increased risk of electric shock if your body is
grounded.
4.
5.
do not expose powered machines to rain or wet conditions. 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
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.
6.
When operating a powered machine outside, use an outdoor extension cord
marked “W-A” or “W”. These extension cords are rated for outdoor use, and
reduce the risk of electric shock.

Tools marked “Double Insulated” do not require grounding. They have a special
double insulation system which satisfies OSHArequirements 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
the preceding illustration. (See outlets for 2-prong plug.)
extenSion CoRdS
1.
2.
Grounded 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
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.)
3.
4.
The smaller the gauge number of the wire, the greater the capacity of the cord. For
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
each cord contains at least the minimum wire size required. (See table A.)

5.
If you are using one extension cord for more than one machine, add the nameplate
amperes and use the sum to determine the required minimum cord size.
(See table A.)
6.
7.
If you are using an extension cord outdoors, make sure it is marked with the suffix
“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.
Always replace a damaged extension cord or have it repaired by a qualified electri-
cian before using it.

Before operation, check the Vacuum Pump oil level. Do this by looking through
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 fill 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.
2.
WARNING: TheA/C (air conditioning) system is under high pressure. Do not loosen
any hose fittings 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
1.
2.
Check the vehicle compressor drive belt. If it is worn or cracked, it should be re-
placed before any other service is performed.
Check the vehicle system hoses. Look for cracks, bubbles, hard spots and dete-
rioration. Inspect all hoses and fittings 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.

Refilling the Automotive System with Oil and Refrigerant
Vehicle manufacturers design for and specify a specific amount of refrigerant for
best operation of your vehicle A/C system. This amount is specified 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.
2.
After recovery, check the amount of used oil separated from the automotive sys-
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.
3.
4.
Check to be sure the HP and LP valves on the Control Panel are open.
Slowly open the Oil Charge Valve (I-9) allowing new oil to be sucked into the au-
tomotive A/C system. Do not open the valve all the way, rather, use it carefully to
control the flow of oil. Allow oil to flow into the system until 10 ml more than the
amount removed has been added back.
5.
6.
When sufficient oil has flowed back into system, close Oil Charge Valve.
Press the “Refilling” Key on the Control Panel. The machine will begin to replace
refrigerant in the vehicle A/C system. The Refilling Indicator light will be on.
7.
NOTE: If the refilling process is taking too long, you can speed the process by using
the vehicle A/C compressor. Turn off the HP valve on the machine Control Panel.
WARning! never turn the vehicle A/C system on if the hp valve is open. Turn the
vehicle A/C system on. The refilling process will go faster.
8.
9.
After system has been completely refilled, the machine will stop automatically.
Close both the HP and LP valves on the Control Panel. Move the Power Switch to
the OFF position. If the vehicle A/C system is running, turn it off.
10.
11.
Slightly loosen the hose connector, allow a few seconds to stabilize any existing pres-
sure in the hoses, and then back off the hose connectors and remove the hoses.
Always test the vehicle A/C system before returning the vehicle to the customer.
Refilling Using an External Refrigerant Tank (Not Included)
