Lowering a vehicle
Check the oil level
Maintenance
1. Turn the handle clockwise to close the release
valve.
2. Pump the handle to lift the handle to lift the vehicle
off the jack stands.
3. Remove the jack stands. Do not get under the
vehicle while the vehicle is being lowered.
4. Turn the handle slowly counter clockwise to lower
the vehicle onto the ground.
1. To check the hydraulic oil level, fully lower the jack
and removed filter plug.
2. The correct oil level should be approximately 5mm
below the filler opening. If oil level is low, fill as
required.
3. Pump unloaded jack 5 or 6 times to expel air and
then refit the plug.
NOTE: use good quality jack oil WARNING!DO
NOT use brake fluid, or anything other than hydraulic
jack fluid as this may cause serious damage to the
jack and invalidate the warranty.
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. Use light oil on moving parts and lightly grease the
handle at the point it fits into the handle socket
2. Use light oil on axles and castor bearings
3. Inject grease into the grease fitting
4. Saddle &linkage-use light oil on all moving and
pivoting parts
5. Handle and socket pivot bolts –use light oil to
lubricate pivot bolts.
6. Plunger & plunger pin –use grease to lubricate
connection be-tween pimp plunger and pin in
handle socket.
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.
3. Consult the vehicle owner’s manual to ascertain
the location of jacking points and position the jack
beneath the lift point.
4. Turn the handle clockwise to the closed position.
5. To raise the vehicle pump the handle up and
down.
6. Place jack stands beneath the vehicle at locations
recommended by the vehicle manufacturer. Do
not work under the vehicle without the use of jack
stands .Jacks are not designed to maintain heavy
loads for long periods of time .Do not attempt to
place jack stands simultaneously under both ends
of a vehicle or along one side of a vehicle.
7. Turn the handle slowly counter clockwise to lower
the vehicle onto the jack stands.
System air purge
1. Turn the handle counter clockwise one full turn to
open .
2. Pump the handle eight full strokes.
3. Turn handle 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. Turn the handle counter clockwise one full turn and
lower the ram to the lowest position. Use force on
the saddle if necessary.
6. Turn the handle 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.
