1. SAFETY PRECAUTIONS
2. SPECIFICATION
3.1. Before first use.
3.1.1. Assemble the handle by lining up the holes in the two-piece
handle and fasten with the assembly screw.
3.1.2. Loosen location bolt at the back of the handle base. Insert the
jack handle and tighten the bolt.
3.1.3. Before using jack, purge the hydraulic unit in order to eliminate
any air in the system. Open the valve by turning the handle
anti-clockwise
(fig.1)
, and pumping 8 or 9 times. When
complete, close the release valve by turning the handle fully
clockwise
(fig.1).
3.1.4. Place a few drops of hydraulic jack oil onto the pump piston
and pump the handle several times to distribute the oil.
Thoroughly lubricate all moving parts.
3.2. General jacking.
p
WARNING!
Before lifting ensure Section 1 safety instructions
are read and understood.
3.2.1. Prepare the vehicle as mentioned in the safety instructions
ensuring the ground on which the jack is to stand is level and
solid (not tarmacadam) and use chocks under wheels of
vehicle.
3.2.2. Position the jack saddle under the vehicle manufacturer’s
recommended lifting point.
3.3. Jacking the vehicle.
3.3.1. Turn the handle clockwise to close the release valve
(fig.1)
and commence pumping handle up and down until the jack
saddle reaches the vehicle jacking point. Check the jacking
point is centrally located on the saddle and continue to pump
the handle to raise the vehicle.
3.3.2. Should the jack become overloaded, a safety excess pressure
valve will open and stop the jack from lifting.
p
WARNING!
The jack is a lifting device only and must not be
used to support the load. Use correctly rated axle stands to
support the load.
3.4. Lowering the vehicle.
p
WARNING!
Ensure there are no persons or obstacles beneath
the vehicle, or in the path of it's descent.
3.4.1. Raise the jack high enough for the axle stands to be easily
removed. Then turn the handle slowly anti-clockwise to open the
release valve
(fig.1)
.
3.4.2. The lowering speed is controlled by the amount the release
valve is opened. Lower carefully, avoiding any sudden
changes in descent rate which could shock load the hydraulic
system.
3. OPERATING INSTRUCTIONS
3
Ensure the jack is in sound condition and good working order.
Take action for immediate repair or replacement of damaged
parts. Use genuine parts only. The use of unapproved parts
may be dangerous and will invalidate the warranty.
3
Locate the jack in a suitable, well lit working area.
3
Keep working area clean and tidy and free from unrelated
materials.
3
Use jack on level and solid ground, preferably concrete. Avoid
tarmacadam as jack may sink in.
3
Place chocks under wheels of vehicle (but ensure wheels of
jack can move freely).
3
Ensure the vehicle's handbrake is engaged, the engine is
switched off and transmission is in gear (or “PARK” if automatic).
3
Ensure minimum distance of 0.5m between vehicle and static
objects such as doors, walls, etc., to allow for vehicle tilting.
3
Ensure there are no passengers in the vehicle.
3
Ensure all non-essential persons keep a safe distance whilst
the jack is in use.
3
Only place jack under vehicle manufacturer’s recommended
lifting points
(see vehicle handbook).
3
Check the lifting point is stable and centred on the jack saddle.
3
Ensure the jack wheels are free to move and that there are no
obstructions.
3
Use correctly rated axle stands under the vehicle before
proceeding with any task.
3
Ensure there are no persons or obstructions beneath the
vehicle before lowering.
3
Use a qualified person to maintain or repair the jack hydraulic
system.
IMPORTANT!
During the jacking operation, ensure that the
vehicle-to-jack saddle contact point are always visible.
p
