1. SAFETY
Disconnect jack from air supply before changing parts, servicing or performing any maintenance.
R WARNING! Ensure correct air pressure is maintained and not exceeded. Recommended pressure 116-145psi or 174psi for
YAJ20-40LR. Required air ow 10.5cfm or 11.5cfm for YAJ20-40LR.
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 qualied person to lubricate and maintain the jack.
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 that there are no obstructions.
V DANGER: Use jack for lifting only, NOT for supporting the raised load. Use correctly rated axle stands under vehicle before
proceeding with task.
DO NOT use brake uid to top up system. Use Sealey hydraulic oil only.
DO NOT apply your body weight to the handle during jacking. The handle is only for moving the jack to and from the lifting 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 lifting 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 pull 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 lowered position in a safe, dry, childproof area.
R 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.
2. INTRODUCTION
Ideal for workshop or roadside use, these jacks take the effort out of lifting heavy plant, tractors and commercial vehicles. Models feature dead
man’s control for extra safety (detachable on Model No’s YAJ15-30DC.V2 and YAJ20-40DC.V2 making these models extremely portable)
and multi-position locking handles. Each jack is supplied with a 45mm and 75mm extension to help close the gap between the saddle of the
jack and the jacking point. Model No. YAJ20-40LR also offers a long reach chassis, ideal for accessing deep set jacking points.

3. SPECIFICATION
Note: The maximum heights shown may be extended by use of the extension pins.
4. ASSEMBLY
4.1. Attaching the Handle - YAJ15-30.V2, YAJ20-40.V2, YAJ20-40LR
4.1.1. Remove a circlip from either side of the large pin (g.1A).
4.1.2. Slide out the pin and place the handle into the opening. Slide the pin back through the jack, lining up the handle and through the
other side. Secure with circlips.
4.2. Air Hoses - YAJ15-30.V2, YAJ20-40.V2, YAJ20-40LR
4.2.1. Screw in the two air hoses from the handle into the jack.
4.2.2. The hose marked orange must be screwed into the left-hand side. The hose marked black or clear into the right-hand side, (g.1).
4.2.3. Ensure the hoses are tight and do not obstruct the movement of the handle.
5. AIR SUPPLY
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 ow of 10.5cfm (or 11.5cfm for
YAJ20-40LR) to get the best performance from this jack.
R 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.
5.3. Drain the air tank daily. Water in the air line will damage the jack.
5.4. Clean the air inlet lter screen weekly.
5.5. Keep the air hose between the compressor and the air jack as short as possible, and install an air lter and oiler (g.2).
5.6. 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 ttings must have the same inside dimensions.
5.7. Keep hose away from heat, oil and sharp edges. Check hoses for wear, and make certain that all connections are secure.
