Norco 72080 Manuals

MODELS 72080 & 72090 20 TON CAPACITY AIR/HYDRAULIC FLOOR JACKS SETUP • OPERATING • MAINTENANCE INSTRUCTIONS BEFORE USING THIS DEVICE, READ THIS MANUAL COMPLETELY AND THOROUGHLY, UNDERSTAND ITS OPERATING PROCEDURES, SAFETY WARNINGS AND MAINTENANCE REQUIREMENTS. FAILURE TO DO SO COULD CAUSE ACCIDENTS RESULTING IN SERIOUS OR FATAL PERSONAL INJURY AND/OR PROPERTY DAMAGE. The use of portable automotive lifting devices is subject to certain hazards that cannot be prevented by mechanical means, but only by the exercise of intelligence, care, and common sense. It is therefore essential to have owners and personnel involved in the use and operation of equipment who are careful, competent, trained, and qualified in the safe operation of the equipment and its proper use. Examples of hazards are dropping, tipping, or slipping of motor vehicles or their components caused primarily by improperly securing loads, overloading, off-centered loads, use on other than hard level surfaces, and using equipment for a purpose for which it was not designed. It is the responsibility of the owner to make sure all personnel read this manual prior to using this device. It is also the responsibility of the device owner to keep this manual intact and in a convenient location for all to see and read. If the manual is lost or not legible, contact Norco Industries, Inc. for a free replacement. If the operator is not fluent in English, the product and safety instructions shall be read to and discussed with the operator in the operator’s native language by the purchaser/ owner or his designee, making sure that the operator comprehends its contents. WARRANTY This product is covered by a Limited Lifetime Warranty. For details see the back cover of Norco’s product catalog. IMPORTANT: READ THESE INSTRUCTIONS BEFORE OPERATING WARNING • Before lifting a vehicle, refer to the vehicle’s service manual or inquire from the vehicle manufacturer the recommended jack lifting points and jack stand support surfaces on the vehicle chassis. • Inspect the jack before each use. Do not use the jack if it is damaged, altered, modified, in poor condition, leaking hydraulic fluid, or unstable due to loose hardware. Take corrective action before using the jack. • This jack was designed for lifting purposes only. Do not attempt to work on the vehicle until jack stands rated equal to or greater than the rated capacity of the jack are positioned to support the load. • Do not move or dolly the vehicle while on the jack. • Do not use the jack beyond its rated capacity. Lift only dead weight. • Do not exceed 100 P.S.I. input air pressure. • Center load on saddle. Be sure setup is stable. Off-center loads can cause jack failure and/or loss of load. • Use the jack on a hard level surface. • Do not modify the jack or use saddle adapters or saddle extenders unless approved or supplied by Norco. • Do not position any part of your body directly above the lifting saddle when operating the jack. • When activating the jack with no load, the ram raises quickly, therefore never put your hands or any other part of your body between the lifting saddle and the load. • Do not use the jack in horizontal or angular positions. • Always lower the jack slowly and carefully. SETUP 1. Refer to the exploded view parts drawing for identification, location and position of parts. 2. The jack is shipped in two cartons. Remove the handle assembly and jack from their respective cartons. 3. An allen socket set screw secures the release collar (#33) to the release shaft (#48) on the handle assembly (#46). Back the set screw off so the collar (#33) freely slides up and down on the release shaft (#48). 4. A universal joint (#32) is assembled to the release valve (#26) on the hydraulic jack. The free end of the universal joint (#26) includes a set screw which must be removed so the release shaft (#48) on the handle assembly (#46) can be slipped into it. Set screw will be installed in step 7. 5. Remove the hex head bolt (#29), lockwasher (#22), and jam nut (#31) from the handle receiver of the jack base. 6. Install the handle assembly (#46) into the handle receiver while at the same time feeding the release shaft (#48) into the universal joint (#32). Align the hole in the handle assembly (#46) with the hole in the handle receiver and secure with the hex bolt (#29), lockwasher (#22), and jam nut (#31) provided. 7. Rotate the release shaft (#48) so the hole at the bottom of the shaft aligns with the set screw hole in the universal joint (#32). Secure the release shaft (#48) in the universal joint (#32) by installing and tightening the allen socket set screw that was previously removed. 8. Rotate the release shaft knob (#34) in a clockwise direction until the release valve (#26) stops and is snug. Now rotate the release valve knob (#34) two full turns in the counterclockwise direction. Slide the release collar (#33) up and flush against the lower guide tab on the handle assembly (#46). Secure the release collar (#33) in this position by tightening the allen socket set screw. NEVER open the release valve (#26) more than two full turns when applying air to the jack or for any other reason except repair. Make sure air is disconnected before removing the release valve. NOTE: Allen socket set screws will not back themselves out of the release collar (#33) or universal joint (#32) if installed and tightened with penetrating thread locker. 9. The end of the air hose (#40) is supplied with a standard 3/8 NPT male quick-disconnect nipple (#45). Make sure your female quickdisconnect is compatible or change it to meet your needs. PURGING AIR FROM THE HYDRAULIC SYSTEM a. Sometimes the jack is shipped, handled or stored in a position other than vertical. This may cause air to be trapped in the pump and cause the ram (#5) to raise in increments instead of a smooth travel. To eliminate this condition perform the following steps: b. Purge the air by turning the release valve knob (#34) two full turns in a counterclockwise direction from its closed position. c. Then depress the air valve button (#43) for about 10 seconds. d. Turn the release valve knob (#34) in a clockwise direction until it stops and is snug. The jack should function properly. Repeat steps “a” through “b” until the jack’s operation is satisfactory.
