ImpoRtANt: Only fully qualified personnel should attempt maintenance or repair.

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. To check the oil level, fully lower the Jack. Remove filler plug (fig.3). 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.

p

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!

5.4. 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.

5.5. Every three months remove the locking rings on the caster wheels and lubricate the ball bearings with acid free grease.

5.6. 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

5.3. for refill instructions.

5.7. Periodically check the pump piston and piston rod for signs of corrosion. Clean exposed areas with a clean oiled cloth.
