Single-piece hydraulic unit. Integral American cog-type release mechanism and long two-piece handle to reduce operator effort. Heavy-duty
castors and large saddle design ease positioning under vehicle. Fitted with safety overload valve and pump-through valve to prevent handle
locking at maximum ram extension. Under 30kg Gross weight for easier transportation and manoeuvrabilty.

NOTE: It is our policy to continually improve products and as such we reserve the right to alter data, specifications and component parts without prior notice.
IMPORTANT: No liability is accepted for incorrect use of this product.
WARRANTY: Guarantee is 12 months from purchase date, proof of which will be required for any claim.
5.3.2. Should the jack become overloaded, a safety excess pressure valve will open, and stop the jack from
lifting.
5.3.3. 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 floor. For this reason use on a hard level concrete surface only.
5.4. Lowering the Load
The lowering speed is controlled by the amount the handle is turned. 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.

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: 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 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.
IMPORTANT: NO RESPONSIBILITY IS ACCEPTED FOR INCORRECT USE OF THE JACK.
Hydraulic products are only repaired by local service agents. We have service/repair agents in all parts of the UK.
