9Locate the jack in a suitable, well lit work area.
9Keep work area clean and tidy and free from unrelated materials.
9Use jack on level and solid ground, preferably concrete. Avoid tarmacadam as jack may sink in.
9Place wedges under wheels of vehicle (but ensure wheels of jack can move freely).
9Ensure the vehicle handbrake is engaged, engine is switched off and transmission is in 1st or reverse gear
(“PARK” if automatic).
9Ensure minimum distance of 0.5m between vehicle and static objects such as doors, walls, etc., to allow for
vehicle tilting.
9Ensure there are no passengers in the vehicle.
9Ensure all non-essential persons keep a safe distance whilst the jack is in use.
9Only place jack under those lifting points recommended by vehicle manufacturer (see vehicle handbook).
9Check the lifting point is stable and centred on the jack saddle.
9Ensure the jack wheels are free to move and that there are no obstructions.
▲DANGER: Use the jack for lifting only, NOT for supporting the lifted load.
9Use suitable capacity axle stands under the vehicle before proceeding with any task.
9Ensure there are no persons or obstructions beneath the vehicle before lowering.
9Use a qualified person to maintain or repair the jack hydraulic system.
8DO NOT operate the jack if damaged.
8DO NOT allow untrained persons to operate the jack.

4.2. Before initial operation, purge any air from the system by fully opening the pump release valve (turn release valve handle
anticlockwise). Then, while holding the saddle down, pump the handle rapidly several times.
4.3. Place a few drops of hydraulic jack oil on the pump piston and pump the handle several times to distribute the oil. Thoroughly lubricate
all moving parts.
5. OPERATION
5.1. Refertogs.1&2
NOTE: Locking lever must be in the upper (jacking) position
before handle can be pumped. Ensure that it is left in the
locked position afterwards.
WARNING! Before lifting, ensure Section 1 safety instructions
are strictly followed.
5.2. Prepare vehicle as described in safety instructions ensuring the
ground on which jack is to stand is level and solid (not tarmacadam).
We recommend concrete.
5.3. Position the jack saddle under the vehicle manufacturer’s
recommended lifting point (see vehicle handbook).
5.4. RAISING THE JACK.
NOTE: The jack saddle may be raised quickly up to the load using the foot pedal.
8DO NOT attempt to raise the load with the foot pedal.
5.4.1. Turn the release valve handle clockwise until resistance is felt to close the
release valve. DO NOT over-tighten.
5.4.2. Place the jack directly under the object to be lifted. Make sure the saddle
accepts weight firmly and centrally. Check positioning under
slight load to confirm jack or load will not slip, or move suddenly.
5.4.3. Raise jack by moving locking lever to the jacking position pump handle
until the desired height is reached. After lifting, secure and transfer load
to axle stands or other appropriate means. DO NOT use jack as the only
means of support.
5.5. LOWERING THE JACK.
5.5.1. Slowly turn the release valve handle anticlockwise. Speed of descent is
controlled by amount release valve is turned.
SAFETY WARNING! Always lower in a slow and controlled manner and
ensure that there are no persons or obstacles beneath the vehicle, or in the path of descent.
6. MAINTENANCE
IMPORTANT: Only fully qualified personnel should attempt maintenance or repair.
6.1. When the jack is not in use, the ram should be in the lowest position to minimise corrosion.
6.2. Keep the jack clean and lubricate all moving parts with oil on a regular basis.
6.3. Every 3 months grease the lifting arm pivot pin and the rear castors via the grease nipples provided.
6.4. The pump and cylinder form a closed hydraulic system and refilling with oil is only necessary in exceptional cases. To check oil level:
1) Place jack on a level surface with the saddle fully lowered.
2) Remove the top cover by pulling up.
3) The oil is topped up via the rubber bung which is situated on top of the cylinder nearest to the ram end of the pump.
NOTE: Use a good quality jack oil, such as SEALEY HYDRAULIC JACK OIL.
WARNING: DO NOT use brake fluid, or any fluid other than hydraulic jack fluid as this will cause serious damage to the jack
and will invalidate the warranty!
6.5. Before each use check for broken, cracked, bent, or loose parts, or any visible damage to ram, pump, saddle, lifting arm, frame and all
parts including nuts, bolts, pins and other fasteners. If any suspect item is found, remove jack from service and take the necessary
action to remedy the problem.
8DO NOT use the jack if it is believed to have been subjected to abnormal or shock loading. Inspect and take appropriate action.
6.6. Periodically check the pump piston and the ram for signs of corrosion. Clean exposed areas with a clean cloth and jack oil.
