5. OPERATION
Before firs
NOTE:
Before using the jack, purge hydraulic circuit in order to eliminate any possible air in the
system by turning the handle anti-clockwise to open the release valve and pumping
15 to 20 times (fig.1). At the end of the last downward stroke shut the valve off again by
turning the handle clockwise.
5.1.
GENERAL
WARNING!
Before lifting ensure section 1 safety instructions are strictly followed.
5.1.1. 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).
5.1.2.
Position the jack saddle under the vehicle manufacturer’s recommended lifting point.
5.2.
JACKING THE VEHICLE (fig.1)
5.2.1.
Turn the handle clockwise to close the valve and commence pumping the handle up and down using maximum strokes until the vehicle
reaches the desired working height.
5.2.2.
Should the jack become overloaded, a safety excess pressure valve will open, and stop the jack from lifting.
5.3.
WEIGHT DISTRIBUTION
5.3.1.
Most of the lifted load is carried by the front jack wheels placing exceptional stress on the point of contact with the floor. For this
reason use on a hard level concrete surface only.
5.4.
LOWERING THE LOAD (fig.1)
WARNING!
Ensure there are no persons or obstacles beneath the vehicle, or in the path of its descent.
5.4.1.
The lowering speed is controlled by the amount the handle is turned. Lower slowly and carefully, avoiding sudden release.
6. MAINTENANCE
IMPORTANT:
Only competent personnel should attempt maintenance or repair.
6.1.
When the jack is not in use, the ram and the handle socket should be in their lowest position
to minimise corrosion. Remove the handle to deactivate jack.
6.2.
Keep the jack clean and lubricate all moving parts with lubricating oil on a regular basis.
6.3.
To check the oil level, fully lower the jack. Remove oil plug (fig.2). The correct oil level should
be approximately 5mm below the filler opening. If oil level is low, fill as required.
Pump unloaded jack 15 to 20 times to expel air and then refit plug.
NOTE
: Only use a good quality jack oil, such as SEALEY HYDRAULIC JACK OIL.
6.4.
Before each use check for broken, cracked, bent, or loose parts, or any visible damage to welds, 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.
6.5.
Every three months remove the locking rings on the caster wheels and lubricate the ball bearings with grease.
6.6.
After a year of extensive use, the oil should be replaced in order to extend the life of your jack. To drain the oil, remove the oil plug
and valve. Make sure that no dirt is allowed to enter the hydraulic system’s oil. Dispose of oil according to local authority regulations. See
6.3. for refill instructions.
6.7.
Check the pump piston and piston rod periodically for signs of corrosion. Clean exposed areas with a clean oiled cloth.
