4. ASSEMBLY
4.1. Fit the handle assembly into the handle socket with the valve control lever towards the jack. Retain with the handle fixing
bolt. See fig.1.
4.2. Before using the jack for the first time, purge the hydraulic circuit in order to eliminate any air in the system. To do this, open
the release valve by moving the lever downwards from position A to position B as shown in fig.2. In the lower position B the handle
must engage with one of the 3 handle locations indicated in fig.1. Once engaged the release valve can be opened by rotating the
lever fully sideways as shown in fig.2-C. Pump the foot pedal through its full travel 3 or 4 times. Return the release valve lever to
the upper closed position (see fig.2-A)
4.3. Place a few drops of hydraulic jack oil on the pump piston and pump the handle several times to distribute the oil. Thoroughly
lubricate all moving parts.
5. OPERATION
5.1. General jacking.
WARNING! Before lifting, ensure Section 1 safety instructions are strictly followed.
5.1.1. Prepare vehicle as described in safety instructions ensuring the ground on which jack is to stand is level and solid (not tarmacadam).
We recommend concrete.
5.1.2. Position the jack saddle under the vehicle manufacturer’s recommended lifting point (see vehicle handbook).
5.2. Jacking the vehicle.
5.2.1. Ensure that the release valve lever is in the upper closed position, see fig.2A. The jack saddle may be raised quickly up to the load
using the foot pedal. DO NOT attempt to raise the load with the foot pedal.
5.2.2. Commence pumping the handle up and down through its full stroke until the vehicle reaches the required height.
Note: If the jack becomes overloaded, the safety valve will operate and prevent the jack from lifting further.
5.3. Lowering the vehicle.
5.3.1. To lower the vehicle, open the release valve by moving the lever downwards from position A to position B as shown in fig.2. In the
lower position B the handle must engage with one of the 3 handle locations indicated in fig.1. Once engaged the release valve can be
opened by rotating the lever fully sideways as shown in fig.2-C.
WARNING! Always lower in a slow and controlled manner and ensure that there are no persons or obstacles beneath the
vehicle, or in the path of 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 the lowest position to minimise corrosion. Remove the handle to inactivate the jack.
6.2. Keep the jack clean and lubricate all moving parts with oil on a regular basis.
6.3. Every 3 months grease the lifting arm pivot pin and the rear castors via the grease nipples provided.
6.4. The pump and cylinder form a closed hydraulic system and refilling with oil is only necessary in exceptional cases. To check oil level:
1) Place jack on a level surface with the saddle fully lowered.
2) Remove the 4 top cover retaining screws and lift off the cover.
3) The oil is topped up via the rubber bung which is situated on top of the cylinder nearest to the ram end of the pump.
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 will cause serious damage to the jack
and will invalidate the warranty!
6.5. 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 the necessary
action to remedy the problem.
8DO NOT use the jack if it is believed to have been subjected to abnormal or shock loading. Inspect and take appropriate action.
6.6. Periodically check the pump piston and the ram for signs of corrosion. Clean exposed areas with a clean cloth and jack oil.
