5. Turn the release valve SLOWLY counterclockwise until the jack begins to lower.
6. Lower the jack slowly as a too fast drop can damage the vehicle.
5. MAINTENANCE
Monthly maintenance is recommended. Lubrication is critical to jacks as they support heavy loads. Any restric-
tion due to dirt, rust etc. can cause either slow movement or extremely rapid jerks, damaging the internal com-
ponents. The following instructions are designed to keep the jack maintained and operational.
-
Lubricate the ram, linkages, saddle and pump mechanism with light machine oil. Grease wheel bearings
and axles.
-
Visually inspect for cracked welds, damages, bent, loose or missing parts and hydraulic oil leaks.
-
If the jack is subjected to abnormal load or shock, or is found damaged or worn in any way, it must be
immediately removed from service until repaired by an authorized service center. Repair may require spe-
cialized equipment and knowledge, so it must only be carried out by an authorized service center, using
original spare parts only.
-
Keep the jack clean and prevent foreign matter such as sand, grit and dirt from entering the system.
-
Clean all surfaces and maintain all labels and warnings in good condition and legible.
-
Check and maintain the ram oil level.
-
Check the ram every three months for any signs of rust or corrosion. Clean as needed and wipe with an
oiled cloth.
-
When not in use, always leave the saddle and ram all the way down.
-
Always store the jack in fully lowered position. This will protect critical areas from excessive corrosion.
-
Store the jack in a clean and dry place where it will not be exposed to corrosive vapours, abrasive dust or
any other harmful elements.
-
Annual inspection of the jack is recommended in an authorized service center to ensure the jack is in op-
timum condition.
Checking the oil level
1. Turn the release valve counterclockwise to allow the ram to fully retract. It may be necessary to apply
force to the saddle for lowering.
2. With the jack in level position, remove the oil fill plug. The oil level should be at the bottom of the filling
hole. If not, top off. Do not overfill. Always fill with new, clean hydraulic jack oil, never use brake or trans-
mission fluids, alcohol or regular motor oil.
3. Replace the oil fill plug.
4. Check jack operation.
5. Purge air from the system if necessary.
Purging air from the system
1. Turn the release valve counterclockwise one full turn to open.
2. Pump the handle eight full strokes.
3. Turn the release valve clockwise to close the valve.
