4.1.
Introduction.
Powerful and reliable, this jack is ideal for workshop or roadside use, taking
the effort out of lifting heavy plant, tractors and commercial vehicles.
The jack features a pneumatic ‘deadman’ control lever,
as indicated in fig.6, which automatically returns to the ‘off’ position when
the lever is released. The jack is supplied with one spacer to close the
gap between the saddle of the jack and the jacking point. The spacer can
be stowed in a special holder on the frame of the jack so that it is always
readily available for use (See fig.3-A). The jack has a multi-position
handle, as indicated in fig.5, which will lock in three different positions,
horizontal (4), 450 (3), and vertical (2) and may be fully collapsed for
transit and storage (1).
4.2. assembly
Ensure the jack is not connected to the air supply before performing the
following.
4.2.1. Before operating the jack, remove the four screws from the cover
and lift the cover off the base unit. Remove the metal rod (fig. 2A) which is
inserted into connector ‘B’. To do this you will need to press and hold down
the rim of connector ‘B’ before you can withdraw the rod.
Take the end of the disconnected blue plastic tube as shown in
fig.2-C which will be found beneath the cover and fully insert it into
connector ‘B’. (Fig.2 shows the internal arrangement of Model MAJ15-30.
Other models, may vary slightly in layout but will still require
the same connection procedure).
4.2.2. Screw the floor stop pin (fig.4-P) into the under side of the handle plate.
4.2.3. With the handle in position No.4 (fig. 5) screw bolt and washer into position
at the base of the handle (See fig.3-B). With this bolt in position the handle
movement is restricted to positions 2,3 & 4. If position 1 is required for
storage or transit purposes it will be necessary to remove the bolt.
5.1.
Preparation before use.
5.1.1. You will require an air pressure of more than100PSI, (max 145PSI) and an
air flow of 9.5 cfm to operate jack.
5.1.2. Connect the air supply hose (fig 4.0).
5.1.3. Set the handle to the required angle using the handle release lever shown
in fig. 6 Pull the lever upwards towards the main handle. Move the handle
to the required position (fig. 5) and release the lever to lock it into position.
5.2. eliminate any air in the system.
Before using the jack, purge the hydraulic circuit in order to eliminate any
possible air that may have entered the system during transit.
5.2.1. Push the control lever (fig.6) to the ‘down’ position and hold it there for
several seconds. Release the lever to the centre ‘hold’ position.
5.2.2. 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.
5.2.3. Repeat the raising and lowering cycle until the movement is smooth. Once
this has been achieved this indicates that all air has been expelled.
5.3.
Using the jack.
WaRnInG!
ensure you have read and understood the safety instructions
in chapter 1 before commencing work.
5.3.1. Position the Jack under the vehicle manufacturer’s recommended jacking
point
(see vehicle hand book).
5.3.2. Whilst holding the main jack handle lifting is achieved by pushing the
control lever (fig.6) to your right.
5.3.3. 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.
5.3.4. Place axle stands correctly in position and ensure chapter 1 safety
instructions are strictly applied before performing any task.
5.4.
Lowering the jack.
5.4.1. Ensure there are no persons or obstruction beneath the vehicle before
lowering, and remove any axle stands.
5.4.2. Whilst holding the main jack handle lowering is achieved by pushing the
control lever to your left, and the jack will lower in a controlled manner.
5.4.3. Once completely lowered releasing the control lever will return it to the
middle hold position. Remove the jack from under the vehicle. If you have
finished using the jack, turn the air pressure supply off and disconnect the
jack from the air line and store the jack and air line accordingly.
