5. OPERATION
5.1. Air sometimes gets into the hydraulic system, causing poor lifting
performance. Before initial operation, to purge any air from the system
open the release valve at the top of the jack handle by turning it anti-
clockwise. Place a weight on the saddle and pump the jack handle rapidly
several times, then close the release valve.
5.2. RAISING THE JACK

release valve. DO NOT over tighten
5.2.2. Place jack directly under object to be lifted. Make sure weight is positioned
centrally.Checkpositioningunderslightloadtoconrmjackorloadwillnotslip.
5.2.3. Raise jack by pumping handle until desired height is reached.
5.2.4. After lifting to required height support on axle stands.
5.3. LOWERING JACK
5.3.1. Slowly turn handle knob anti clockwise. Speed is controlled by amount release
valve is turned.
8DO NOT lower the jack too fast so as to loose control.
