THE NATURE OF HAZARDOUS SITUATIONS The use of portable automotive lifting devices are 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 the equipment who are careful, competent, trained and qualified in the safe operation of the equipment and its proper use. Examples of haz- ards are dropping, tipping or slipping of loads 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. METHODS TO AVOID HAZARDOUS SITUATIONS • Read, study, understand and follow all instructions before operating this device. � � •� Inspect�the�jack�before�each�use.�Do�not�use�if�damaged,�altered,�modified,�in�poor�condition,�leaking�hydraulic�fluid�or�unstable�due�� � to loose or missing components. Make corrections before using. • Use only on a hard level surface free from obstructions so the jack is free to reposition itself during lifting and lowering operations. � � •� Lift�only�on�areas�of�the�vehicle�as�specified�by�the�vehicle�manufacturer. • User and bystanders must wear eye protection that meets ANSI Z87.1 and OSHA standards. • Do not use jack beyond its rated capacity. Do not shock load. • No persons should be under vehicle when jack is in use. • This is a lifting device only. Immediately after lifting, support the vehicle with jack stands capable of sustaining the load before working on the vehicle. • Center load on saddle. Be sure setup is stable before working on vehicle. • Do not move or dolly the vehicle while on the jack. • Do not use any materials that may serve as risers, spacers or extenders between the stock lifting saddle and the load. • Do not use any adaptors that replace the stock lifting saddle unless approved or supplied by the jack manufacturer. • Do not use (or modify) this product for any other purpose than that for which it was designed without consulting the manufacturer's authorized representative. • Always lower the jack slowly and carefully. • Failure to heed these warnings may result in serious or fatal personal injury and/or property damage. WARNING: This product can expose you to chemicals including nickel, which is known to the State of California to cause cancer and birth defects or other reproductive harm.

CONSEQUENCES OF NOT AVOIDING HAZARDOUS SITUATIONS Failure to read this manual completely and thoroughly, failure to understand its OPERATING INSTRUCTIONS, SAFETY WARNINGS, MAINTENANCE INSTRUCTIONS and comply with them, and failure to comply with the METHODS TO AVOID HAZARDOUS SITUATIONS could cause accidents resulting in serious or fatal personal injury and/or property damage. WARNING: Indicates a hazardous situation which, if not avoided, could result in death or serious injury. WARNING WARNING WARNING WARNING 791-9001 3 08/22/18 SETUP PLEASE REFER TO THE EXPLODED VIEW DRAWING IN THIS MANUAL IN ORDER TO IDENTIFY PARTS. 1. Install the handle assembly (#79) in the housing (#74) so the holes in the lower portion of the handle line up with the holes in the housing. Push the handle yoke pivot shaft (#81) through all the holes and secure the shaft on both ends with the retaining rings provided. 2. Turn the entire jack on its side in order to hook up the clear and black air hoses that are coming out of the bottom of the handle (#79). As you are facing the back of the jack, pull the clear and black hoses back towards you and route them over the top of the pivot shaft (#81) so that they are in line to engage the connectors in the back of the tank (#105). Firmly push the black hose into the connector labeled "black tube" and the clear hose into the connector labeled "clear tube". Pull on both hoses after they are installed into the connectors to make sure they are firmly seated. Turn the jack upright. 3. Install an air nipple that is suitable for your shop in the switch assembly (#77). Use pipe dope tape to seal the nipple in the switch assembly and be careful not to let any excess tape enter the air system. Do not over-tighten the nipple as this could strip the threads in the switch. 4. Install the lever (#106) in the switch assembly (#77) and tighten. 5. Install the adapters (#75) in the holder at the base of the housing. 6. Hook the shop air line quick disconnect onto the nipple. 7. Due to the back pressure release system design of this jack, the jack’s hydraulic system very rarely becomes air bound. Indication of an air bound system is a ram that does not rise smoothly. In some extreme case of an air bound system, air can be purged by following this procedure: PURGING AIR FROM THE HYDRAULIC SYSTEM a. Pump the jack to maximum height by turning the air lever all the way to the right. After maximum height is reached, turn the air lever to the left to lower the jack all the way down. b. Repeat step “a” several times until all air is purged from the system. OPERATING INSTRUCTIONS This is the safety alert symbol used for the OPERATING INSTRUCTIONS section of this manual to alert you to potential personal injury hazards. Obey all instructions to avoid possible injury or death. IMPORTANT: Before attempting to raise any vehicle, check vehicle service manual for recommended lifting surfaces. OPERATION: 1. Become familiar with the identification and function of the operating jack components. a. The rams (#95 and #100) are the shafts that come out of the jack when you rotate the switch assembly lever (#106) to the right. Lowering the ram is accomplished by rotating the lever to the left. b. The saddle (#99) has a hole in it to receive the adapters (#75). The adapters can be stacked on top of each other for additional height. Evaluate the work to be done to determine if there is enough ram stroke to lift the load. Adding adapters can bring the jack closer to the load so you can get more effective ram stroke. 2. Chock the vehicle’s tires that will not be lifted off the ground prior to lifting the vehicle and if available, apply the emergency brake or any other method of braking. 3. With the jack in its lowered position and the handle all the way down and locked, push the jack under the vehicle and to its designated lift point. Lock the handle in a position that will not interfere with the vehicle when raised or lowered. Keep the handle in that locked position until the work is completed and you are ready to remove the jack from use. 4. In most cases, between 116 and 174 psig input air pressure (do not exceed 200 psig) will lift the maximum capacity load. Rotate the air lever to the right until the top of the ram comes close to the designated lift point. Make sure the designated lift point is flat, parallel to the ground and free from grease, any kind of lubricant, and debris. Never get under the vehicle when the jack is being used. Proceed with pumping the jack in order to lift the vehicle to the desired height. During lifting, inspect the position of the jack in relation to the ground and the ram in relationship to the load to prevent any unstable conditions from developing. If conditions look like they are becoming unstable, slowly lower the load and make appropriate setup corrections after the load is lowered. 5. When the vehicle or load is lifted to its desired height, immediately place jack stands capable of safely supporting the load in their designated positions and adjust the stands’ support columns up as close to the designated vehicle support points as possible. Although jack stands are individually rated, they are used in a matched pair to support one end of the vehicle only. Stands are not to be used to simultaneously support both ends or one side of a vehicle. Rotate the air lever to the left to lower the vehicle onto the jack stands. Make sure the vehicle is safely supported by the jack stands’ saddles and not the locating lugs of the saddles. Inspect the relationship of the jack stands with the ground and the jack stand columns and saddles with the vehicle to prevent any unstable conditions. If conditions look unstable, rotate the air lever to the right to raise the vehicle off the jack stands. Make appropriate setup changes and slowly and carefully lower the vehicle onto the jack stands. OPERATING MANUAL FOR 791-9001
