VENTING PROCEDURE
During delivery or after topping up with oil, air can get into the hydraulic system and lead to poor lifting
performance on the appliance. In such a case it is necessary to bleed the air as follows:
1. Fully turn the release valve anti-clockwise to completely open the release valve.
2. Pump with the pump lever several times with quick movements.
3. Turn the release valve clockwise to close the release valve.
4. Pump with the pump lever until the lifting arm reaches its maximum height and continue with the
pumping movements to allow air trapped in the thrust plate to escape.
5. Fully turn the release valve anti-clockwise to lower the lifting arm to its lowest position. If necessary
exert force on the plate.
6. Turn the release valve clockwise to close the release valve and check the pump action is working
properly. It may be necessary to repeat the above steps several times to ensure that all the air can
escape from the system.
STORAGE & CARE
•
When the vehicle jack is not in use, the lifting arm (5) / saddle (6) should be in the lowest position and
the pumping lever (1) in an upright position to protect the precision mechanics from damage.
•
The vehicle jack must be stored in a horizontal position and in a dry location. Ensure the jack remains
in its original condition. Do not undertake any modifications to the device.
•
Use only SAE10 (SAE: Society of Automotive Engineers) grade, special-purpose hydraulic oil for the
hydraulic pump. Dispose of all used and spilled oil appropriately.
•
Do not use a high pressure cleaner to clean the jack. All external moving parts, e.g. the foot roller
bearings, fastening bolts of the lifting arm, fastening bolts of the lifting arm cylinder and fastening bolts
of the pumping arm must be well lubricated regularly every 3 months.
IMPORTANT: Never lubricate or grease the pump piston and lifting rod.
•
All maintenance and repair work must be performed by a suitably qualified personnel an in
accordance with the manufacturer's instructions.
•
Caution: Do not use the jack if there are any missing, loose or broken parts!
