1. Safety
IMPORTANT: READ ALL INSTRUCTIONS BEFORE USE
Regularly inspect and lubricate the jack to ensure it is in good
working order and condition. DO NOT use the jack if damaged
or a fault is suspected - check Section 6 Troubleshooting. If
necessary, immediately repair or replace damaged parts.
• Use recommended parts only, the use of unauthorised parts
may be dangerous and will invalidate your warranty.
• Ensure the work area is clean, tidy and free from unrelated
materials and has adequate lighting.
• Use jack on level and solid ground, preferably concrete.
Avoid tarmacadam since jack may sink in.
• Park the vehicle and apply hand brake (if automatic, place in
“Park” mode). Switch off the engine and place chocks under
the wheels.
• Ensure a minimum distance of 0.5m between vehicle and
static objects such as doors, walls, etc. to allow for tilting
during jacking.
• Ensure all persons are out of the vehicle before jacking.
DO NOT enter vehicle whilst it is supported on the jack or
axle stands.
• Check vehicle weight and recommended lifting points by
referring to the vehicle owner’s manual. Ensure the lifting
point is not corroded.
• Check 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.
• Keep 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. Traffic
may cause vehicle to rock. Use hazard warning lights. If in
doubt call professional help.
• When changing a wheel, slightly loosen wheel nuts/bolts
prior to jacking vehicle. Screw wheel nuts/bolts back before
lowering vehicle. Finally tighten when vehicle is fully lowered.
• Use a qualied person to lubricate and maintain the jack.
Conrm that only recommended hydraulic jack oil is used
during maintenance.
• DO 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.
• Ensure there are no persons or obstructions beneath the
vehicle before lowering.
• Clean and securely stow the jack with the ram in the down
position. DO NOT leave the ram extended. Ensure stowage
area is dry.
WARNING! Remember, it is very dangerous to go under a
vehicle supported by a jack even if additional supports are used.
DANGER! USE THE JACK FOR LIFTING ONLY, NOT
FOR SUPPORTING THE LIFTED LOAD. ALWAYS USE
ADEQUATELY RATED AXLE STANDS.
• DO NOT jack a vehicle if it may result in the spillage of fuel,
battery acid, or other dangerous substances.
• DO 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.
• DO NOT use jack to support extensions or cradles.
DO NOT modify jack in any way. DO NOT use the jack
for any other purpose.
• DO NOT top up jack with brake uid. Use hydraulic oil only.
DO NOT adjust the safety overload valve.
• DO NOT go under a vehicle unless it is supported by
adequately rated axle stands. NOTE: Seek advice before
jacking caravans or trailers.

WARNING! BEFORE LIFTING ENSURE SECTION 1 SAFETY INSTRUCTIONS
ARE STRICTLY FOLLOWED.
1. Line up the holes in the two-piece handle and fasten with the assembly screw.
2. Loosen the location bolt at the side of the handle base. Insert jack handle and
tighten the bolt.
LIFTING
WARNING! ENSURE YOU PREPARE VEHICLE AND USE JACK ACCORDING TO
SECTION 1 SAFETY INSTRUCTIONS.
• Check that the ground upon which the jack will stand is level and solid.
• Position the jack saddle 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.
• Using the screw extension as necessary, raise the saddle to the lifting point. Ensure
that the saddle is correctly centred beneath the lifting point.
• Pump the handle up and down using full stroke until the required lift is achieved.
• Should the jack become overloaded, a safety overload valve will open, and stop the
vehicle from lifting.
• Lower the vehicle onto suitable axle stands before attempting any work.
LOWERING
• 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.
• The lowering speed is controlled by the amount the release valve is opened.
Turn valve anti-clockwise and lower slowly and carefully.
WARNING: DO NOT USE THE JACK IF YOU BELIEVE IT HAS BEEN SUBJECTED TO ABNORMAL LOAD OR SHOCK.
INSPECT AND TAKE APPROPRIATE ACTION.
• 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.
• Periodically check the pump piston and piston rod for signs of corrosion. Clean exposed areas with a clean oiled cloth.

6. Troubleshooting
IMPORTANT: ONLY FULLY QUALIFIED PERSONNEL SHOULD ATTEMPT MAINTENANCE OR REPAIR
WARNING: DO NOT USE BRAKE FLUID, OR ANY FLUID OTHER THAN HYDRAULIC JACK FLUID, AS TO DO SO MAY
CAUSE SERIOUS DAMAGE TO THE JACK AND WILL INVALIDATE THE WARRANTY!
• When the jack is not in use, the ram and piston must be in their lowest positions to minimise corrosion.
Remove the handle to inactivate jack.
• Keep the jack clean and lubricate all moving parts with acid free oil on a regular basis.
• To check the hydraulic oil level, fully lower the jack and remove the oil ller plug (Fig. 2). The correct oil level should be
approximately 5mm below the ller opening. If oil level is low, ll as required.
• 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.
• To replace the oil ll as required. Pump unloaded jack 5 or 6 times to expel air and then ret the plug.
Note: Ensure waste oil is disposed of in accordance with local authority regulations.
TO PURGE AIR FROM THE SYSTEM
• Turn the handle counter clockwise one full turn to open.
• Pump the handle eight full strokes.
• Turn handle clockwise to close the valve.
• Pump the handle until the ram reaches maximum height and continue to pump several times to remove air trapped in the ram.
• Turn the handle counter clockwise one full turn and lower the ram to the lowest position. Use force on the saddle if necessary.
• Turn the handle clockwise to the closed position and check for proper pump action. It may be necessary to perform the above
procedure more than once to ensure all the trapped air is evacuated.
