Safety & Maintenance |
OPERATING INSTRUCTIONS- Position jack under vehicle or other object to be lifted. Always be sure lift pad or lift point is centered
- Front wheels and casters of floor jacks must be free of obstructions so the jack can travel under load. Otherwise the lifting pad is liable to slip off or put undue strain on point being lifted. Vehicle must be out of gear and brake released when lifting.
- To lift - turn handle or release knob clockwise and pump. If jack is air-bound, open release by turning handle or knob counter-clockwise, hold open and pump rapidly about 4 full strokes. Then close release and pump jack to full height without load. Open release and lower jack. THIS STEP MAY HAVE TO BE REPEATED SEVERAL TIMES TO BLEED ALL THE AIR FROM JACK
LUBRICATION- Oil front wheels, caster bearings, all linkages and moving parts periodically
- Grease lift arm at grease fitting (if so equipped) and lower end of handle at yoke casting
IMPORTANT USE JACK FOR LIFTING ONLY. TO INSURE SAFETY, ALWAYS SUPPORT VEHICLE OR LOAD WITH STANDS OR OTHER SUITABLE DEVICES SUCH AS TIMBERS, ETC. |

SERVICE INSTRUCTIONSCONDITION-Jack does not rise when pumped CAUSE-Release valve not closed.Valve balls not seated. Jack out of oil CORRECTION-Twist handle clockwise. Remove valve balls and clean. Reseat by tapping balls lightly on their seats using a brass rod & small hammer. Check oil level and fill to proper level. Jack does not lift to full heightCORRECTION-Lower jack to down position. Remove oil filler plug. Add clean HYDRAULIC JACK OIL to cover the cylinder or, if an upright jack, to the fill hose in the reservoir. DO NOT USE BRAKE FLUID or STANDARD HYDRAULIC OIL!!. Use ONLY HYDRAULIC JACK OIL. CONDITION-Jack creeps down under loadCAUSE-Release ball or discharge ball leaking. Piston cup is leaking
Remove & clean discharge ball if jack handle rises under load. Rebuild jack using repair kit.
GENERAL INSTRUCTIONS- When rebuilding your jack, always replace all of the parts that are supplied in your repair kit
- Some repair kits are "Universal" kits that fit several series of jacks. You may find parts in these kits that are not used in your particular model
- Use only HYDRAULIC JACK OIL. Regular hydraulic oil may be too heavy and cause problems in cooler weather. NEVER use Brake Fluid.
- Always clean all parts of your jack before installing new parts
- Most floor jack are supplied with a SAFETY OVERLOAD VALVE. Generally, these Safety Valves are not field repairable.
- Keep track of where the old parts come from when disassembling the jack. This will make the installation of the new parts easier.
- DO NOT OVERLOAD YOUR JACK - Too heavy a load may cause a hydraulic or structural failure leading to damage, injury or death.
