Important:
only fully qualified personnel should attempt maintenance or repair.
WaRnInG!
Disconnect jack from air supply before changing parts, servicing or performing any maintenance.
6.1.
When the jack is not in use, the ram must be in the lowest position to minimise corrosion.
6.2.
Keep the jack clean and lubricate all moving parts, and the air intake connector with air tool oil on a regular basis.
6.3.
To check oil level, fully lower jack. Remove the filler plug/dipstick. The oil level should be between the two marks on the dipstick. Top
up the oil level if necessary but do not overfill as the jack will become inoperative. If inadvertently overfilled the excess oil should be
poured off. After topping up or pouring off excess oil it may become necessary to purge air from the unit. See section 5.2.
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!
WaRnInG!
wear safety goggles.
6.4.
Ensure the air filter located in the air valve is cleaned in the same manner.
6.5.
Should the piston not rise and the oil level and operation is correct, this may indicate a problem with air seeping into the hydraulic
valve passage. Purge any air from the system. See section 5.2.
6.6
Confirm that the piston can rise to the highest position.
6.7.
Before each use check for broken, cracked, bent, or loose parts. Or any visible damage to welds, ram, pump, saddle, air connector,
levers, 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.
6.8.
Every three months remove the locking rings on the caster wheels and lubricate the ball bearings with acid free grease.
6.9.
After a year of extensive use, the oil should be replaced in order to extend the life of your equipment. To drain the oil, remove the filler
plug and valve. Make sure that no dirt is allowed to enter the hydraulic system’s See 6.3. for refilling instructions.
6.10.
Periodically check the pump piston and piston rod for signs of corrosion. Clean exposed areas with a clean oiled cloth.
