5. OPERATION
IMPORTANT SAFETY WARNING:
ALWAYS USE AXLE STANDS
Please remember a trolley jack is a lifting device and is not designed to support a load. Never get underneath a vehicle supported
only by a jack - your life is at risk. We stock a comprehensive range of axle stands - please see relative section for full details.
5.1.
BEFORE FIRST USE
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.
5.2.
GENERAL
WARNING!
Before lifting ensure chapter 1 safety instructions are strictly followed.
5.2.1.
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).
5.2.2.
Position the jack saddle under the vehicle manufacturer’s recommended lifting point. (See vehicle handbook for details).
5.3.
JACKING THE VEHICLE
5.3.1.
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.
5.3.2.
Should the jack become overloaded, a safety excess pressure valve will open, and stop the jack from lifting.
5.4.
WEIGHT DISTRIBUTION
Up to 80% of the lifted load is carried by the front jack wheels placing exceptional stress on the point of contact with the supporting
floor. For this reason use on a hard level concrete surface only.
5.5.
LOWERING THE LOAD
The lowering speed is controlled by the amount you turn the handle. Lower slowly and carefully, avoiding sudden release.
WARNING!
Ensure there are no persons or obstacles beneath the vehicle, or in the path of its descent.
6. MAINTENANCE
IMPORTANT:
Only fully qualified personnel should attempt maintenance or repair.
6.1.
When the jack is not in use, the ram should be in its lowest position to minimise corrosion. Remove the handle to deactivate jack.
6.2.
Keep the jack clean and lubricate all moving parts with oil on a regular basis.
6.3.
To check the oil level, fully lower the jack. Remove filler 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:
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 fluid as this may cause serious damage to the jack and
will invalidate the warranty!
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.
Inspect and take appropriate action.
6.5.
Every three months remove the locking rings on the caster wheels and lubricate the ball bearings with acid free 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 filler
cap 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.
Periodically check the pump piston and piston rod for signs of corrosion. Clean exposed areas with a clean oiled cloth.
IMPORTANT:
NO RESPONSIBILITY IS ACCEPTED FOR INCORRECT USE OF THE JACK.
