Store in a dry place with the ram fully lowered. If stored for long periods, inspect at least once a year, clean and re-oil.
TO LOWER:
1. Lift the vehicle to remove the weight from any supports.
2. Remove the axle stands or other supports from below the vehicle.
3. SLOWLY turn the knob on the handle counterclockwise to open the release valve.
NOTE: This operation must be done very slowly and in full control. DO NOT let the load lower suddenly, this
could damage internal components.
4. Remove the jack from below the vehicle.
NOTE: The jack can move slightly during operation. It is important that the area is clean and free from all debris.
9. SAFETY INSTRUCTIONS
1. This jack is for lifting only, do not move a load using the jack as a dolly.
2. Do not use to lift people.
3. Always inspect the jack before use. Make sure that all parts are in good condition and operating smoothly, and
that no cracks or distortion is apparent.
4. Make sure that the jack is on a firm solid base, and there is no possibility of it slipping when under load.
5. Make sure the load is taken by the full saddle and that the point of lift on the load, is strong enough to support the
load adequately.
6. Do not work under the raised vehicle until it is supported by suitable means e.g. axle stands, NEVER rely on the
jack to support the vehicle by itself.
