1. SAFETY 99 9 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: 116-174psi Required air flow:

11.5cfm 9 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. 9 Ensure jack is kept clean and in good working order. Repair or replace damaged parts immediately 9 Use recommended parts only. Incorrect parts may be dangerous and will invalidate the warranty. 9 Use a qualified person to lubricate and maintain the jack. 8 DO NOT use brake fluid to top up system. Use Sealey hydraulic oil only. 9 Locate jack in a suitable, well lit work area. Keep area clean and tidy and free from unrelated materials. 9 Use jack on level & solid ground, preferably concrete. Avoid tarmacadam since jack may sink in. 9 Place chocks under wheels of vehicle. 9 Ensure the vehicle handbrake is engaged (or in PARK mode), and switch the engine off. 9 Ensure minimum distance of 0.5m between vehicle as it tilts & static objects such as doors, walls, etc. 9 Ensure all non essential persons keep a safe distance and that there are no passengers in the vehicle to be jacked up. 9 Place jack under vehicle manufacturers recommended jacking points (see vehicle handbook). 9 Check that the jacking point is stable and centred on the jack saddle and is free from grease or oil. 9 9 DANGER: Use jack for lifting only, NOT for supporting the raised load. Use correctly rated axle stands under vehicle before proceeding

with task. 98 9 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. 98 9 DO NOT operate the jack if parts are missing or damaged. 98 9 DO NOT exceed the rated capacity of the jack. 98 9 DO NOT allow the vehicle to move during lifting. 98 9 DO NOT jack a vehicle which may result in the spillage of fuel, battery acid, or dangerous substances. 98 9 DO NOT work under the vehicle until axle stands have been positioned correctly. 8 DO NOT use the jack for purposes other that those for which it is designed. 98 9 DO NOT adjust the safety overload valve. 98 9 DO NOT snatch the hose from the air supply, and DO NOT direct air from the air hose at yourself or others. 99 9 Ensure there are no persons or obstructions beneath the vehicle before lowering. 9 When not in use disconnect jack from the air supply, and store in the lowered position in a safe, dry, childproof area. 9 9 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. i INTRODUCTION Ideal for workshop or roadside use, these jacks take the effort out of lifting heavy plant, tractors and commercial vehicles.

4. ASSEMBLY

4.1. Attaching the Handle 4.1.1. Removethecirclipfromeithersideofthelargepin(fig.1). 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 4.2.1. Screw in the black and clear hoses from the handle into the jack. Ensure that the black and clear hoses are wrapped around the

handle, inserting as shown by the label positioned beneath the connection points on the jack (fig.1A). Position so as to 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. Youwillrequireanairpressureofbetween116psiand174psiandanairflowof11.5cfmtogetthebestperformancefromthisjack. 5.3. 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.

5.4. Drain the compressors 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.

6. OPERATION 6.1. Preparation 6.1.1. Check that the air supply meets the requirements set out in section 5. 6.1.2. Connecttheairsupplytotheconnector(fig.4B). 6.1.3. Setthehandletotherequiredangleusingthehandlereleaselevershowninfig.4A.Pulltheleverupwardstowardsthemainhandle.

Move the handle to the required position and release the lever to lock it into position. 6.2. Purging the system 6.2.1. Beforeusingthejack,purgethehydrauliccircuitinordertoeliminateanypossibleairthatmayhaveenteredthesystemduringtransit. 6.2.2. Push the control lever (fig.3) to the down (fig.3A) position and hold it there for several seconds. Release the lever to the centre hold

position. 6.2.3. Nowpushthelevertotheupposition(fig.3B)andholditthereuntilthejackisfullyextended.Pushthelevertothedown(fig.3A)

position and watch the jack as it retracts. The lowering movement should be smooth and without irregular stops. 6.2.4. 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 6.3.1. Repeat the raising and lowering cycle until the movement is smooth. Once this has been achieved this indicates that all air has been

expelled. 9 9 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 manufacturers recommended jacking point (see vehicle hand book). Note: Use the extension pins (fig.4D) to get the jack closer to the jacking point before engaging the jack. 6.3.2. Whilst holding the main jack handle, lifting is achieved by pushing the controllevertotheupposition(fig.3B). 6.3.3. 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. 6.3.4. Place axle stands correctly in position and ensure section 1 safety instructions are strictly applied before performing any task.

6.4. Lowering the Jack 6.4.1. Ensure there are no persons or obstruction beneath the vehicle before lowering, and remove any axle stands. 6.4.2. Whilst holding the main jack handle lowering is achieved by pushing the control lever to down position (fig.3A), and the jack will lower

in a controlled manner. 6.4.3. Once completely lowered releasing the control lever will return to the middle hold position.

6.4.4. Removethejackfromunderthevehicle.Ifyouhavefinishedusingthejack,turntheairpressuresupplyoffanddisconnectfromthe air line and store the jack and air line accordingly.

7. MAINTENANCE IMPORTANT: Only fully qualified personnel should attempt maintenance or repair.

9 9 WARNING! Disconnect jack from air supply before changing parts, servicing or performing any maintenance. 7.1. When the jack is not in use, the piston must be in the lowest position to minimise corrosion. 7.2. Keep the jack clean and lubricate all moving parts with air tool oil on a regular basis. 7.3.

After topping up or pouring off excess oil it may become necessary to purge air from the unit. See section 6.2. WARNING! DO NOT use brake fluid, or any fluid other than hydraulic jack fluid as this may cause serious damage to the jack and will

invalidate the warranty! 7.4. Ensuretheairfilterlocatedintheairvalveisclean. 7.5. Should the piston not rise and the oil level is correct, this may indicate a problem with air seeping into the hydraulic valve passage.

Purge any air from the system. See 6.2 7.6. Confirmthatthepistoncanrisetothehighestposition. 7.7. Beforeeachusecheckforbroken,cracked,bent,orlooseparts;anyvisibledamagetowelds,piston,pump,saddle,airconnector,
