MAINTENANcE
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 acid free oil on a regular basis.
5.3.
To check the oil level, fully lower the jack. Remove filler plug. The correct oil level should be approximately 5mm below the filler
opening. If oil level is low, fill as required, then pump unloaded Jack 8 or 9 times to expel air and refit the oil fill plug.
NOTE: Use a good quality jack oil, such as SEALEY HYDRAULIC JACK OIL. (Sealey Part No: HJO500MLS or HJO5LS)
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 castor wheels and lubricate the ball bearings with grease.
5.6.
After a year of extensive use, the oil should be replaced in order to extend the life of your equipment. To drain the oil, lay the jack on its
side, remove the oil filler cap and allow to drain into a suitable container. Make sure that no dirt is allowed to enter the hydraulic
system. 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.
