4. OPERATION
IMPORTANT SAFETY WARNING! ALWAYS USE RATED STANDS
Please remember a jack is a lifting and lowering device and is not designed to support a load. Never get underneath a vehicle supported
only by a jack; your life is at risk. We stock a comprehensive range of axle stands, for example, please see relevant catalogue section for
full details. The jack is not limited to vehicle use only, with many applications in the engineering and construction industries.
WARNING! Before use refer to section 1. SAFETY
4.1. PURGING THE JACK
Purge the hydraulic system in order to eliminate any air that may have accumulated in transit or whilst stored:
a) Place the telescopic jack lever over the release valve and turn anti clockwise to open the valve.
b) Insert the telescopic jack lever into the sleeve of the hydraulic pump.
c) Pump several times to ensure complete evacuation of air from the system.
d) When complete place the telescopic lever over the release valve and turn clockwise to close.

4.2.2. Depending upon the height to be lifted, adjust the extension screw to suit.
4.2.3. Insert the telescopic jack lever into the sleeve of the hydraulic pump until the spring catch engages. Pump the lever, full stroke range,
so that the saddle quickly reaches the load to be lifted. Depress the spring catch with a screwdriver to remove.
4.2.4. Observe carefully the load and jack whilst elevating to the required height.
4.2.5. When the load is at the required height, place correctly rated stand or stands beneath the load near the jacking point.

anticlockwise to open the valve. Remove the jack if required for access.
4.3. LOWERING THE LOAD
