MAINTENANCE
MONTHLY MAINTENANCE IS RECOMMENDED. LUBRICATION IS CRITICAL TO JACKS AS THEY
SUPPORT HEAVY LOADS. ANY RESTRICTION DUE TO DIRT, RUST OR CORROSION CAN CAUSE
EITHER SLOW MOVEMENT OR RAPID JERKS DAMAGING THE INTERNAL COMPONENTS. THE
FOLLOWING STEPS ARE DESIGNED TO KEEP THE JACK MAINTAINED AND OPERATIONAL.
1.
LUBRICATE THE RAM, LINKAGES, SADDLE AND PUMP MECHANISM WITH LIGHT OIL.
2.
VISUALLY INSPECT THE JACK FOR CRACKED WELDS, BENT, LOOSE OR MISSING PARTS
AND HYDRAULIC OIL LEAKS.
3.
IF THIS JACK IS FOUND TO BE DAMAGED IN ANY WAY OR OPERATING ABNORMALLY
IT SHOULD BE REMOVED FROM SERVICE UNTIL REPAIRED BY AN AUTHORISED SERVICE
CENTRE.
4.
CLEAN ALL SURFACES AND MAINTAIN ALL LABELS AND WARNINGS.
5.
CHECK AND MAINTAIN THE RAM OIL LEVEL.
6.
CHECK THE RAM EVERY 3 MONTHS FOR SIGNS OF RUST OR CORROSION. CLEAN AS
NEEDED AND WIPE WITH AN OILY CLOTH. WHEN NOT IN USE ALWAYS LEAVE THE SAD-
DLE AND RAM FULLY RETRACTED.
ALWAYS STORE THE JACK IN THE FULLY LOWERED POSITION. THIS WILL HELP PROTECT
CRITICAL AREAS FROM CORROSION. DO NOT USE BRAKE OR TRANSMISSION FLUIDS OR
REGULAR MOTOR OIL AS THEY CAN DAMAGE THE SEALS. ALWAYS REFILL WITH HYDRAULIC
JACK OIL.
CHECK THE OIL LEVEL
1.
TURN THE RELEASE VALVE COUNTER CLOCKWISE TO ALLOW THE RAM TO FULLY RE-
TRACT. IT MAY BE NECESSARY TO APPLY FORCE TO THE SADDLE TO LOWER THE RAM.
2.
REMOVE THE INSPECTION PLATE.
3.
WITH THE JACK IN THE LEVEL POSITION REMOVE THE OIL FILL PLUG. STAND THE JACK
IN THE VERTICAL POSITION WITH THE HANDLE SOCKET DOWN. THE OIL SHOULD BE
LEVEL WITH THE BOTTOM OF THE FILL HOLE. IF NOT, TOP UP BUT DO NOT OVERFILL.
ALWAYS FILL WITH NEW, CLEAN HYDRAULIC JACK OIL.
4.
REPLACE FILL PLUG AND INSPECTION PLATE.
5.
CHECK JACK OPERATION.
6.
PURGE AIR FROM THE SYSTEM AS REQUIRED.
SYSTEM AIR PURGE
1.
TURN THE RELEASE VALVE COUNTER CLOCKWISE ONE FULL TURN TO OPEN.
2.
PUMP THE HANDLE EIGHT FULL STROKES.
3.
TURN RELEASE VALVE CLOCKWISE TO CLOSE THE VALVE.
4.
PUMP THE HANDLE UNTIL THE RAM REACHES MAXIMUM HEIGHT AND CONTINUE TO
PUMP SEVERAL TIMES TO REMOVE AIR TRAPPED IN THE RAM.
5.
CAREFULLY AND SLOWLY PINCH THE OIL FILL PLUG TO RELEASE TRAPPED AIR.
6.
TURN THE RELEASE VALVE COUNTER CLOCKWISE ONE FULL TURN AND LOWER THE
RAM TO THE LOWEST POSITION. USE FORCE ON THE SADDLE IF NECESSARY.
7.
TURN THE RELEASE VALVE CLOCKWISE TO THE CLOSED POSITION AND CHECK FOR
PROPER PUMP ACTION. IT MAY BE NECESSARY TO PERFORM THE ABOVE MORE THAN
ONCE TO ENSURE ALL THE TRAPPED AIR IS EVACUATED.
