PLEASE READ THESE INSTRUCTIONS CAREFULLY. NOTE THE SAFE OPERATIONAL REQUIREMENTS, WARNINGS & CAUTIONS. USE
THE PRODUCT CORRECTLY AND WITH CARE FOR THE PURPOSE FOR WHICH IT IS INTENDED. FAILURE TO DO SO MAY CAUSE DAMAGEAND/OR
PERSONAL INJURY AND WILL INVALIDATE THE WARRANTY. KEEP THESE INSTRUCTIONS SAFE FOR FUTURE USE.
1. SAFETY
9Inspect and lubricate the jack regularly to ensure it is in good working order and condition. DO NOT use the jack if damaged or a fault
is suspected - check Section 5 Troubleshooting. If necessary, immediately repair or replace damaged parts.
9Use recommended parts only, the use of unauthorised parts may be dangerous and will invalidate your warranty.
9Ensure the work area is clean, tidy and free from unrelated materials and has adequate lighting.
9Use jack on level and solid ground, preferably concrete. Avoid tarmacadam since jack may sink in.
9Park the vehicle and apply hand brake (if automatic, place in “Park” mode). Switch off the engine and place chocks under the wheels.
9Ensure a minimum distance of 0.5m between vehicle and static objects such as doors, walls, etc. to allow for tilting during jacking.
9Ensure all persons are out of the vehicle before jacking. DO NOT enter vehicle whilst it is supported on the jack or axle stands.
9Check vehicle weight and recommended lifting points by referring to the vehicle owner’s manual. Ensure the lifting point is not corroded.
9Check lifting point is centred and stable on jack saddle (off centre loads can slip). Position jack so as to avoid operating it from under
vehicle.
9Keep all unauthorised persons away from the jack when lifting and lowering.
▲DANGER! Use the jack for lifting only, NOT for supporting the lifted load. ALWAYS USE ADEQUATELY RATED AXLE STANDS.
9Keep hands etc. clear of moving parts during raising and lowering of the vehicle.
▲DANGER! Roadside wheel changing is hazardous. Be extra vigilant, you may not be able to avoid jacking on tarmacadam. Get
everyone out of vehicle. NEVER go under vehicle. Trafc may cause vehicle to rock. Use hazard warning lights. If in doubt call
professional help.
9When changing a wheel, loosen wheel nuts/bolts slightly prior to jacking vehicle. Screw wheel nuts/bolts back before lowering vehicle.
9Tighten nally when vehicle is lowered fully.
9Use a qualied person to lubricate and maintain the jack. Conrm that only recommended hydraulic jack oil is used during maintenance.
8DO NOT exceed the rated capacity of the jack and DO NOT operate the jack beyond its maximum pump stroke.
WARNING! DO NOT allow the vehicle to move, or try to start the engine, when the vehicle is jacked up.
8DO NOT jack a vehicle if it may result in the spillage of fuel, battery acid, or other dangerous substances.
8DO NOT place any part of your body under vehicle whilst it is supported by the jack. Wait until adequately rated axle stands have
been correctly positioned.
8DO NOT use jack to support extensions or cradles. DO NOT modify jack in any way. DO NOT use the jack for any other purpose.
8DO NOT top up jack with brake uid. Use Sealey hydraulic oil only (Part No: HJO500MLS or HJO5LS).
8DO NOT allow untrained persons to operate the jack.
8DO NOT remove any labels from the jack. If labels are damaged or unclear, replace them.
8DO NOT operate the jack when you are tired, under the inuence of alcohol, drugs or intoxicating medication.
9Ensure there are no persons or obstructions beneath the vehicle before lowering.
9Clean and securely stow the jack with the ram in the down position. DO NOT leave the ram extended.
9When not in use, store the jack in a safe, dry, childproof area.
WARNING! Remember, it is very dangerous to go under a vehicle supported by a jack even if additional supports are used.
8DO NOT go under a vehicle unless it is supported by adequately rated axle stands. NOTE: Seek advice before jacking caravans or trailers.

4. OPERATION
WARNING! Before lifting ensure Section 1 Safety Instructions are followed strictly.
4.1. Before using the jack, purge the hydraulic system, in order to eliminate any air that may
have accumulated during transit, referring to g.1 as follows:
a) Fit jack handle over release valve (1) and turn anti-clockwise to open valve.
b) Insert jack handle into the handle sleeve (2) and pump several times to ensure full
internal lubrication and to bleed air from the system.
c) Fit jack handle back over the release valve (1) and turn clockwise to close.
WARNING! Ensure you prepare vehicle and use jack according to Section 1
4.2. Safety Instructions.
4.2.1. Check that the ground upon which the jack will stand is level and solid.
4.2.2. Position the jack saddle (4) under the vehicle manufacturer’s recommended lifting
point. Position jack so as to avoid having to operate it from under the vehicle and so
that the handle can be moved up and down without hitting any part of the vehicle.
4.2.3. Using the screw extension as necessary, raise the saddle to the lifting point. Ensure
that the saddle is centred correctly beneath the lifting point.
4.2.4. Pump the handle up and down using the full stroke until the required lift is achieved.
4.2.5. Should the jack become overloaded, a safety overload valve will open, and stop the
vehicle from lifting.
4.2.6. Lower the vehicle onto suitable axle stands before attempting any work.
4.3. Lowering
4.3.1. Ensure that the axle stands are removed and that there are no persons or obstacles
beneath the vehicle, or in the path of its descent.
4.3.2. The lowering speed is controlled by the amount the release valve (1) is opened. Turn
valve anti-clockwise and lower slowly and carefully.
5. MAINTENANCE
IMPORTANT: Only fully qualied personnel should attempt maintenance or repair.
WARNING: DO NOT use brake uid, or any uid other than Sealey hydraulic jack uid (Part No: HJO500MLS or HJO5LS), as to do
so may cause serious damage to the jack and will invalidate the warranty!
5.1. When the jack is not in use, the ram and piston must be in their lowest positions to minimise corrosion. Remove the handle to
secure the jack.
5.2. Keep the jack clean and lubricate all moving parts with acid free oil on a regular basis.
5.3. To check oil level, lower the jack fully. Remove ller plug. The correct oil level is to the bottom of the ller opening.
5.4. After a year of extensive use, the oil should be replaced in order to extend the life of the jack. Drain the oil through the ller plug
opening. Make sure that no dirt is allowed to enter the jack or the fresh oil.
5.5. To replace the oil, ll as required. Pump (unloaded jack) 5 or 6 times to expel air. Pump jack to full height and pour off excess oil
before retting plug.
Note: Ensure waste oil is disposed of in accordance with local authority regulations.
5.6. Before each use check for broken, cracked, bent, or loose parts. Also check for any visible damage to welds, ram, pump, body and
base.
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 believed to have been subjected to abnormal load or shock. Inspect and take appropriate action.
5.7. Check the pump piston and piston rod periodically for signs of corrosion. Clean exposed areas with a clean oiled cloth.
