1. SafetY InStRUCtIonS
 Disconnect jack from air supply before changing parts, servicing or performing any maintenance.
 WaRnInG! Ensure correct air pressure is maintained and not exceeded. Recommended pressure 100-145psi. Required air flow 9.5cfm.
 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 Jack is kept clean and in good working order. Immediately repair or replace damaged parts.
 Use recommended parts only. Incorrect parts may be dangerous and will invalidate the warranty.
 Use a qualified person to lubricate and maintain the jack. DO NOT use brake fluid to top up system. Use Sealey hydraulic oil only.
 Locate jack in a suitable, well lit work area. Keep area clean and tidy and free from unrelated materials.
 Use jack on level & solid ground, preferably concrete. Avoid tarmacadam since jack may sink in.
 Place wedges under wheels of vehicle (but ensure wheels of jack can freely move).
 Ensure the vehicle handbrake is engaged (or in "PARKED" mode), and switch the engine off.
 Ensure minimum distance of 0.5m between vehicle tilt & static objects such as doors, walls, etc.
 Ensure all non essential persons keep a safe distance and that there are no passengers in the vehicle to be jacked up.
 Place jack under vehicle manufacturer's recommended jacking points (see vehicle handbook).
 Check that the jacking point is stable and centred on the jack saddle and is free from grease or oil.
 Ensure jack wheels are free to move and there are no obstructions.
 DanGEr: Use jack for lifting only, NOT for supporting the jacked load. Use correct axle stands under vehicle before proceeding
with task.
 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 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 during jacking and do not use the jack to move the vehicle.
 DO NOT jack a vehicle which may result in the spillage of fuel, battery acid, or dangerous
substances.
 DO NOT work under the vehicle until Axle Stands have been correctly positioned.
 DO NOT use the jack for purposes other that than which it is designed for.
 DO NOT adjust the safety overload valve.
 DO NOT yank the hose from the air supply, and DO NOT direct air from the air hose at
yourself or others..
 Ensure there are no persons or obstructions beneath the vehicle before lowering.
 When not in use disconnect jack from the air supply, and store in the down position 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.

3. aIR SUPPLY
3.1. Ensure that the jack pneumatic switch is in the "off" position before connecting to the air supply.
3.2. You will require an air pressure of more than 100psi (max 145psi) and an air flow of 9.5cfm to get the best performance from this jack.
3.3.  WaRnInG! Ensure the air supply does not exceed 145psi 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.
3.4. Drain the air tank daily. Water in the air line will damage the jack.
3.5. Clean the air inlet filter screen weekly.
3.6. Keep the air hose between the compressor and the air jack as short as possible, and install an air filter and oiler
(fig 1).
3.7. 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.
3.8. Keep hose away from heat, oil and sharp edges. Check hoses for wear, and make certain that all connections
are secure.
