Lowering
Open the bleed valve slowly by turning the handle anti-clockwise until the valve opens a little. Do not turn
so far that the valve comes loose from the seat.
MAINTENANCE

When the jack is not in use, it must be stored in the fully lowered position. This protects the piston
rod and the pump piston against corrosion.

Use type SAE 10 hydraulic oil for the best results.

Clean the jack and lubricate external moving parts such as the spindle, wheels, cotter and gudgeon
pin.
