▲DANGER! Use the jack for lifting and lowering only. ▲DANGER! DO NOT place any part of the body beneath the lifted load unless the load is fully supported by rated stands.▲DANGER! DO NOT place any part of the body beneath the load during lifting or lowering.
8DO NOT exceed the rated capacity of the jack, load or maximum stroke.8DO NOT adjust the overload valve, modify or use the jack for any purpose other than for which it is designed(lifting and lowering
mechanical devices).
8DO NOT leave elevated loads unattended, unless safe from others in a garage or workshop.8DO NOT modify the jack.
9Ensure the jacking area is solid and level. Increase the jacking area with a solid flat plate (steel) if jacking on tarmacadum or grass.9Keep others away from the work area.9Ensure the jacking area is clutter free and that there is adequate lighting.

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

4.2. LIFTING THE LOAD
4.2.1. Position the jack beneath the jacking point of the load to be lifted and on to an area that is solid and level.
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.
4.2.6. Lower the load carefully and slowly on to the stand or stands. Place the telescopic jack lever over the release valve and turn
anticlockwise to open the valve. Remove the jack if required for access.
4.3. LOWERING THE LOAD
4.3.1. Position the jack beneath the jacking point of the load to be lifted and on to an area that is solid and level.
4.3.2. Depending upon the height to be lifted, adjust the extension screw to suit.
4.3.3. 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.
4.3.4. Observe carefully the load and jack whilst elevating to the required height.
4.3.5. Remove the stand or stands.
4.3.6. Lowertheloadcarefullyandslowlyontotheoor.Placethetelescopicjackleveroverthereleasevalveand
