4.1.
Before first use
4.1.1.
Before using jack for the first time, purge the hydraulic unit in order to eliminate any air in the system. Place handle (fig.1.H) onto the
release valve (B) and open valve by turning the handle anti-clockwise, place handle back into the jacking point (A) and pump for 30 to
40 seconds. When complete, close the release valve by turning the valve (B) clockwise. When lifting a load of maximum capacity or
close to it, it is recommended that the effort be reduced by the use of assistance during this operation.
4.1.2.
Place a few drops of hydraulic jack oil on pump piston and pump handle several times to distribute oil. Thoroughly lubricate moving
parts.
4.2.
general jacking
Warning!
Before lifting ensure Section 1 safety instructions are read and understood.
4.2.1.
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).
4.2.2.
Position the jack saddle under the vehicle manufacturer’s recommended lifting point.
4.3.
jacking the vehicle
4.3.1.
Place the handle onto the release valve (B) and turn it clockwise to close the valve. Place handle into socket (A) 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.
4.3.2.
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.
4.4.
loWering the vehicle
4.4.1.
If using axle stands, raise the jack high enough for the stands to be easily removed. Then place handle on release valve (B) and turn
anti-clockwise, very slowly, to open the valve.
4.4.2.
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. Maintenance
5.1.
When the jack is not in use, the ram should be in its lowest position to minimise corrosion. Remove the handle to inactivate jack.
5.2.
Keep the jack clean and lubricate all moving parts with oil on a regular basis.
5.3.
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.
5.4.
Periodically check the pump piston and the ram for signs of corrosion. Clean exposed areas with a clean oiled cloth.
5.5.
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.
5.6.
To check the oil level, fully lower the jack. Remove front cover plate (fig.1.C) and filler plug (fig.2.o). The correct level is the bottom of
the screw hole. If oil level is low, fill as required. Pump jack 5 or 6 times to expel air. Pump jack up to full height and pour off excess oil
before refitting plug.
do not touch the safety overload valve (fig.2.v).
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!
5.7.
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.
