The transmission jack is now ready for use.

IMPORTANT : Before EACH use, check jack is in sound working order, use following list to form a habitual pre-check procedure.

Check unit for the following : Damage, Distortion, Leaning, Worn or Missing Components.

The following must also be checked

Saddle base
Piston rod
Cylinder/Hydraulic unit
Stopper rings and cotter pins
All nuts and bolts
All seals
Jack main frame
Foot pumps
Swivel caster wheels
Transport handle

WARNING! DO NOT use jack if any suspect part is found, or if believed to have been subjected to abnormal load or shock. Immediately remove from service and contact your authorised service agent.

IMPORTANT
Before using the jack for the first time, purge the hydraulic circuit in order to eliminate any air, that may have accumulated in the system during transit, as follows

Open the release valve by turning knob anti-clockwise (fig.3) and hold the valve open.
Operate the foot pedal 15 to 20 times.
Release the valve (which will turn clockwise to close the valve).

OPERATION

WARNING! Before use ensure you have read, understood and apply Section 1 Safety Instructions.
WARNING! Ensure you prepare vehicle correctly before attempting to use the Transmission Jack.

POSITIONING JACK BENEATH LOAD

Before use ensure the transmission weight and size does not exceed the capacity of the jack.
Ensure the vehicle from which the gearbox is to be removed is correctly positioned, handbrake applied and raised to allow the transmission jack to be positioned correctly.
Ensure there are no other persons around or under the vehicle.
Ensure saddle is in its lowest position and use handle to transport and centrally position jack beneath vehicle transmission.
Pump the jack foot pedal and the saddle will rise (fig.2).
When saddle is just beneath the transmission re-adjust alignment if necessary to centralize the saddle.

LOWERING THE LOAD

WARNING! Ensure the load is central and stable on the jack saddle and load is fixed in place before attempting to lift, lower, or transport. SLOWLY turn the release valve knob anti-clockwise (fig.3) to GENTLY lower saddle to
the lowest minimum height before attempting to transport load.
IMPORTANT : The unit is fitted with a ‘Dead Man’ release valve. The quicker the valve knob is turned the more rapid the jack’s descent. Ensure the jack’s descent is slow and controlled to avoid the risk of sudden dropping which could be dangerous. The valve will automatically return to the closed position when the knob is released.

TRANSPORTING THE LOAD

Ensure the jack saddle is fully lowered and load is fixed in place before attempting to lift, lower, or transport.
Transport the load over level and solid ground, preferably concrete, and ensure the floor is swept clean beforehand.
Be diligent in continually monitoring the load in transit. Keep all other persons at a safe distance.

DANGER! If jack tips or leans STOP WHAT YOUR ARE DOING. MOVE QUICKLY TO A SAFE DISTANCE. DO NOT TRY TO HOLD OR STEADY JACK.
NOTE : This jack may be used with appropriate adaptors in order to handle such components as rear axle units and transfer cases that are within the weight limitations of the jack.

RE-INSTALLING A GEARBOX
To transport, reposition beneath a vehicle, and raise a load up, reverse the procedures outlined above.

MAINTENANCE

IMPORTANT: Only fully qualified personnel should attempt maintenance or repair.
When the jack is not in use, the saddle must be in the lowest position to minimise ram and piston corrosion. Keep the jack clean and wipe off any oil or grease. Lubricate all moving parts with acid free oil.
