INSPECTION

Visual inspection should be made before each use of the service jack, checking for

leaking hydraulic fluid and damaged, loose or missing parts. Each jack must be

inspected by a manufacturer’s repair facility immediately, if accidentally subjected to

an abnormal load or shock. Any jack which appears to be damaged in any way,

found to be badly worn, or operates abnormally MUST BE REMOVED FROM

SERVICE until necessary repairs are made by a manufacturer’s authorized repair

facility. It is recommended that an annual inspection of the jack be made by a

manufacturer’s authorized repair facility and that any defective parts, decals or

warning labels be replaced with manufacturer’s specified parts.

A list of authorized repair facilities is available from the manufacturer.

OPERATING INSTRUCTIONS

IMPORTANT: Before attempting to raise a vehicle, check vehicle service manual for

recommended lifting surfaces.

1. To raise load: Close release valve tightly (by turning handle knob clockwise).

DO NOT

OVERTIGHTEN.

Position jack under load so that saddle will contact load firmly and load is

centered so it cannot slip. Operate the air valve until saddle approaches the load. Once again

check to see that saddle is correctly positioned. Raise load to desired height. Place jack stands of

appropriate capacity under the vehicle. DO NOT CRAWL UNDER VEHICLE WHILE

LIFTING VEHICLE OR PLACING OR REMOVING JACK STANDS! Place jack stands at

vehicle manufacturer’s recommended lift areas that provide stable support for the raised vehicle.

2. To lower load: Open release valve VERY SLOWLY (by turning handle knob

counterclockwise). When release valve is opened, saddle and load will be lowered. Lower the

vehicle slowly so as not to shock load the jack stands. Once repairs are completed, raise vehicle

enough to remove jack stands. Lower vehicle very slowly.

CAUTION: Keep hands or feet away from the hinge mechanism of the jack.

MAINTENANCE INSTRUCTIONS

IMPORTANT! Use only a good grade hydraulic jack oil. Avoid mixing types of oil. Do

not use brake fluid, alcohol, glycerin, detergent motor oil, or dirty oil. Improper fluid

can cause serious internal damage to the jack, rendering it inoperative.

To Add Oil: With saddle fully lowered and ram depressed, set jack in an upright

position and remove oil filler plug. Fill until oil is level with filler plug hole.

To Change Oil: For best performance and longest life, replace the complete oil supply

at least once a year. To drain the oil, remove the filler plug. Lay the jack on its side

and allow the oil to run out into suitable drain pan. The oil will run slowly because air

must enter as oil drains out. Be careful to prevent dirt or foreign matter from entering

the system. Replace with proper oil.

LUBRICATION

All moving joints require lubrication often. Remove handle and grease the lower end of

handle where the release mechanism rotates in the handle socket.
