5.1.
Attach the handle to the base by means of bolts (fig.2.1) and nuts
(fig.2.2), ensuring that the locking bar (fig.2.3) is engaged in the lugs
(fig.2.4.)
5.2.
Connect the air hoses: ensure that the hose with the red sleeve is
fitted to the right hand connection (fig.2)

Original Language Version
4.
AIR SUPPLY
4.1.
Ensure that the jack pneumatic switch is in the "off" position before connecting to the air supply.
4.2.
Use an air pressure of between 116psi and 174psi and an air flow of 10.5cfm to get the best performance from this jack.
4.3.
WARNING!
Ensure the air supply does not exceed the stated maximum pressure while operating the jack.
Too high an air pressure and unclean air will shorten the products life due to excessive wear, and may be dangerous causing possible
damage and personal injury.
4.4.
Drain the air tank daily. Water in the air line will damage the jack.
4.5.
Clean the air inlet filter screen weekly.
4.6.
Keep the air hose between the compressor and the air jack as short as possible, and install an air filter and oiler (fig.1).
4.7.
Line pressure should be increased to compensate for unusually long air hoses (over 8 metres). The minimum hose diameter should be
3/8" I.D. and fittings must have the same inside dimensions.
4.8.
Keep hose away from heat, oil and sharp edges. Check hoses for wear, and make certain that all connections are secure.

6.1. Preparation
6.1.1. Check that the air supply meets the requirements set out in section 4.
6.1.2. Connect the air supply to the connector (fig.4.3).
6.1.3. Set the handle to the required angle using the handle release lever shown
in fig.4.1. Pull the lever upwards towards the main handle. Move the handle to
the required position and release the lever to lock it into position.
6.2.
Purging the System
Before using the jack, purge the hydraulic circuit in order to eliminate any air
that may have entered the system during transit.
6.2.1. Rotate the control lever (fig.3) to the ‘down’ (fig.3.A) position and hold it there for
several seconds. Release the lever to the centre ‘hold’ position.
6.2.2. Rotate the lever to the ‘up’ position (fig.3.B) and hold it there until the jack is fully extended. Push the lever to the ‘down’ (fig.3.A)
position and watch the jack as it retracts. The lowering movement should be smooth and without irregular stops.
6.2.3. Repeat the raising and lowering cycle until the movement is smooth. Once this has been achieved this indicates that all
air has been expelled.
6.3.
Using the Jack
WARNING!
ensure you have read and understood the safety instructions in section 1 before commencing work.
6.3.1. Position the jack under the vehicle manufacturer’s recommended jacking point (see vehicle hand book)
.
fig.3
fig.4
fig.2
Note: Use the extension pins to get the jack closer to the jacking point before engaging the jack.
Fine adjustment is available by using the screw extension in the centre of the piston (fig.5)
6.3.2. Whilst holding the main jack handle, lifting is achieved by rotating the control lever to the 'up'
position (fig.3.B).
6.3.3. When the vehicle has reached the desired height release the control lever which will
return to the middle hold position.This will stop any further air flow automatically and hold the jack.
6.3.4. Place axle stands in position correctly, lower the load onto them and ensure section 1 safety
instructions are applied strictly before performing any task.
6.4.
Lowering the Jack
6.4.1. Ensure there are no persons or obstruction beneath the vehicle before lowering.
6.4.2. Raise the the load clear of any axle stands and remove them.
6.4.3. Whilst holding the main jack handle lowering is achieved by rotating the control lever to down
position (fig.3.A), and the jack will lower in a controlled manner.
6.4.4. Once lowered completely releasing the control lever will return to the middle hold position.
Remove the jack from under the vehicle. When finished, turn the air supply off and disconnect from
the air line and store the jack and air line accordingly.
