5.1.1.
General
WaRNING! before lifting ensure Section 1 safety instructions are read and understood.
‰
5.1.1.1.
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).
5.1.1.2.
Position the jack saddle under the vehicle manufacturer's recommended lifting point.
5.1.2.
Jacking the vehicle
5.1.2.1.
Turn the handle clockwise to close the release valve (fig 1B) place handle in jacking point (fig 1A) and commence pumping handle up
and down, using maximum strokes, until the jack saddle reaches the vehicle jacking point. Check the jacking point is centrally located on
the saddle and raise the vehicle.
5.1.2.2.
Should the jack become overloaded, a safety excess pressure valve will open, and stop the vehicle from lifting.
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.
‰
When lifting a load of maximum capacity (2 tonne) or close to it, it is recommended that the effort be reduced by the use of assistance
during this operation.
5.1.3.
Lowering the vehicle
5.1.3.1.
If using axle stands, raise the jack high enough for the stands to be easily removed. Then place handle on release valve nut (fig 1B)
and turn anti-clockwise, very slowly, to open the valve.
5.1.3.2.
The lowering speed is controlled by the amount you turn the handle. Lower carefully, avoid any sudden changes in descent rate
which would shock load the hydraulic system.
WaRNING! Ensure there are no persons or obstacles beneath the vehicle, or in the path of its descent.
‰
5.2.
aXLe STaNDS
ensure the maximum load does not exceed 2 tonnes per pair of axle stands (1 tonne for each stand).
5.2.1.
Refer to vehicle owner's handbook for correct jacking procedure. Check to ensure that manufacturer's recommended jacking points are
in good condition.
5.2.2.
Ensure the vehicle parking brake is on and wheels are chocked.
5.2.3.
Ensure the stand legs are fully extended and adjust height of stand to correspond with the raised vehicle.
5.2.4.
Check that the locking pin (fig 2.1) is correctly pushed all the way through the centre column and out of the other side, then position
stands under vehicle at points specified by vehicle manufacturer.
5.2.5.
Carefully and slowly lower the load onto stands. Ensure the jacking points sit in the centre of the stand saddles and check that the stands
are stable and not leaning.
5.2.6.
After use, hold the centre column (fig 2.2) firmly when removing the locking pin (fig 2.2). Failure to do so will allow the centre column to
fall freely through the main centre tube which could be dangerous.
WaRNING! Ensure you follow all instructions carefully. DO NOT load stands off centre. Failure to heed this warning may cause damage,
‰
serious injury or loss of life!

6.1.1.
When the jack is not in use, the ram should be in its lowest position to minimise corrosion. Remove the handle to inactivate jack.
6.1.2.
Keep the jack clean and lubricate all moving parts with acid free oil on a regular basis.
6.1.3.
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 necessary
action to remedy the problem.
DO NOT use the jack if believed to have been subjected to abnormal load or shock load.
8
6.1.4.
Periodically check the pump piston and the ram for signs of corrosion. Clean exposed areas with a clean oiled cloth.
6.1.5.
After one year the oil should be replaced in order to extend the life of the jack. Use hydraulic jack oil only.
IMpORTaNT: Only fully qualified personnel should attempt hydraulic maintenance or repair.
6.1.6.
To check the oil level, fully lower the jack. Remove filler screw (fig 1.O). The correct level is the bottom of the screw hole. If oil level is low,
.
fill as required
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 oil as this may cause serious damage to the jack and will
‰
invalidate the warranty!
6.1.7.
To drain the oil, remove the filler plug and raise front of jack. Make sure that no dirt is allowed to enter the hydraulic system.
IMpORTaNT: NO ReSpONSIbILITy IS aCCepTeD fOR INCORReCT uSe Of ThIS pRODuCT.
