1. SAFETY

 Disconnect jack from air supply before changing parts, servicing or performing any maintenance.
 WARNING! ensure correct air pressure is maintained and not exceeded.
 Keep air hose away from heat, oil and sharp edges. Check air hose for wear before each use, and ensure that all connections are secure.

 Ensure the jack is in sound condition and good working order. Take action for immediate repair or replacement of damaged parts.

Use genuine parts only. Unauthorised parts may be dangerous and will invalidate the warranty.

 Use jack on level and solid ground, preferably concrete. Avoid tarmacadam as jack may sink in.
 Place wedges under wheels of vehicle.
 Ensure the vehicle handbrake is engaged, engine is switched off and transmission is in gear (or “Park” if automatic).
 Ensure minimum distance of 0.5m between vehicle and static objects such as doors, walls, etc., to allow for vehicle tilting.
 Only place jack under those lifting points recommended by vehicle manufacturer (see vehicle handbook).

 Check that the jacking point is stable and centred on the jack saddle and is free from grease and oil.

 Locate the jack in a suitable, well lit work area.
 Keep work area clean and tidy and free from unrelated materials.
 Use a qualified person to maintain or repair the jack’s hydraulic system.
 Ensure there are no passengers in the vehicle.
 Ensure all non-essential persons keep a safe distance whilst the jack is in use.

 DANGER: Use the jack for lifting only, NOT for supporting the lifted load.

 Use suitable capacity axle stands under the vehicle before proceeding with any task.
DO NOT allow untrained persons to operate the jack.

 DO NOT operate the jack if parts are missing or damaged.
 DO NOT exceed the rated capacity of the jack.

DO NOT allow the vehicle to move while supported by the jack.
DO NOT jack the vehicle if there is a risk of spillage of fuel, battery acid, or other dangerous substances.
DO NOT work under the vehicle until axle stands have been correctly positioned.
DO NOT use the jack for purposes other than that for which it is intended.
DO NOT adjust the safety overload valve.

 DO NOT apply your body weight to the handle during jacking. The handle is only for moving the jack to and from the jacking location.
 DO NOT direct air from the air hose at yourself or others.

 DO NOT use the jack if believed to have been subjected to abnormal load or shock. Inspect and take appropriate action.
 Ensure that there are no persons or obstructions beneath the vehicle before lowering.

 When not in use disconnect jack from the air supply, and store, fully lowered, in a safe, dry, childproof area.
 WARNING! Turn off air supply and de-pressurise the control nozzle before removing the pump unit from any installation or mobile system.

Failure to comply with this instruction may damage the unit and will invalidate your warranty.

INVALIDATE THE WARRANTY. KEEP THESE INSTRUCTIONS SAFE FOR FUTURE USE.

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.

5. ASSEMBLY

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)

6. OPERATION

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
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).

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.

(fig.3.B)

and hold it there until the jack is fully extended. Push the lever to the ‘down’ (fig.3.A)
