5.1.
Ensure that the jack pneumatic switch is in the "off" position
before connecting to the air supply.
5.2.
You will require an air pressure of at least 116psi (max 145psi
or 174psi for YAJ20-40LR) and an air flow of 10.5cfm or
11.5cfm for YAJ20-40LR to get the best performance from this
jack.
5.3.
WaRnInG!
Ensure the air supply does not exceed 145psi
or 174psi for YAJ20-40LR 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.
5.4.
Drain the air tank daily. Water in the air line will damage the
jack.
5.5.
Clean the air inlet filter screen weekly.
5.6.
Keep the air hose between the compressor and the air jack as
short as possible, and install an air filter and oiler (fig.2).
5.7.
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.
5.8.
Keep hose away from heat, oil and sharp edges. Check hoses
for wear, and make certain that all connections are secure.

Preparation - yaJ15-30, yaJ20-40, yaJ20-40LR
6.1.1. You will require an air pressure of at least 116psi (max
145psi or 174psi for YAJ20-40LR) and an air flow of 10.5cfm
or 11.5cfm for YAJ20-40LR to get the best performance from
the jack.
6.1.2. Connect the air supply to the connector (fig.3B).
6.1.3. Set the handle to the required angle using the handle release
lever shown in fig.3A. 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.
Preparation - yaJ15-30DC, yaJ20-40DC
6.2.1. Connect the air supply to the connector (fig.4A).
6.2.2 To change the handle position on the "DC" models turn the
handle (fig.4D) anti-clockwise then pull out of socket, insert
into the other handle socket and turn clockwise to secure.
6.2.3 On the "DC" models the controls (fig.4B) are detachable, lift
and slide off the handle before putting the jack under the
vehicle.

Purge the System - yaJ15-30, yaJ20-40, yaJ20-40LR
Before using the jack, purge the hydraulic circuit in order to
eliminate any possible air that may have entered the system
during transit.
6.3.1. Push the control lever (fig.5A) to the ‘down’ position and hold
it there for several seconds. Release the lever to the centre
‘hold’ position.
6.3.2. Now push the lever to the ‘up’ position and hold it there until
the jack is fully extended. Push the lever to the ‘down’
position and watch the jack as it retracts. The lowering
movement should be smooth and without irregular stops.
6.3.3. Repeat the raising and lowering cycle until the movement is
smooth. Once this has been achieved this indicates that all
air has been expelled.
6.4.
Purge the System - yaJ15-30DC, yaJ20-40DC
Before using the jack, purge the hydraulic circuit in order to
eliminate any possible air that may have entered the system
during transit.
6.4.1. Push the down button (fig.6B) and hold it there for several
seconds. Release the button.
6.4.2. Now push the 'up' button and hold it there until the jack is
fully extended. Push the 'down' button and watch the jack as
it retracts. The lowering movement should be smooth and
without irregular stops.
6.4.3. Repeat the raising and lowering cycle until the movement is
smooth. Once this has been achieved this indicates that all
air has been expelled.

WaRnInG!
ensure you have read and understood the
safety instructions in chapter 1 before commencing work.
6.5.1. Position the Jack under the vehicle manufacturer’s
recommended jacking point
(see vehicle hand book).
Note: Use the extension pins (fig.3D) to get the jack closer
to the jacking point before engaging the jack. See
specification for capacity when using the extension pins.
6.5.2. Whilst holding the main jack handle lifting is achieved by
pushing the control lever to the 'up' position (fig.5B).
6.5.3. When the vehicle has reached the desired height release the
control lever which will automatically return to the middle
hold position stopping any further air flow holding the jack at
the height to which it has been raised.
6.5.4. Place axle stands correctly in position and ensure chapter 1
safety instructions are strictly applied before performing any
task.
