KENNEDY Bottle Jacks are designed to help you work safely and efficiently. Lifting
equipment can be dangerous if the correct operating and maintenance procedures are not
followed. Operating instructions and basic safety procedures are as follows:

Valve
OPERATINg INSTRUCTIONS
1. Assemble the pump handle by fitting the smaller
tubes into the larger tube using the bolts provided.
2. To engage the pressure piston use the slotted end
of the pump handle, turn the release valve
clockwise until tight.
3. Position the Jack under the vehicle so that the load
plate will be centred under a specified jacking point.
4. Insert the pump handle into the piston assembly &
pump the handle to raise the load.
5. Once the load has been raised to the required
height, use an additional support (i.e. correctly
rated axle stands) before continuing work.
6. To lower the vehicle, raise the jack in order to
remove the additional supports. Insert the slotted
end of the pump handle into the release valve &
turn it anti-clockwise no more than one complete
turn. The speed at which the vehicle is lowered can
be controlled by how far the release valve is turned.
REFILLINg ThE OIL RESERVOIR
1. Only refill the oil with the jack in an upright position.
2. The Jack's piston should be in the lowest position.
3. Remove the rubber stopper from the cylinder housing.
4. Using hydraulic oil ISO VG.22/32, fill to the lower rim of
the stopper hole.

BLEEDINg ThE SYSTEM
1. Using the slotted end of the pump handle turn the
release valve anti-clockwise no more than one
complete turn.
2. Remove the rubber oil stopper from the cylinder
housing.
3. Insert the pump handle into the piston assembly &
pump the handle several times to force out any air.
4. Turn the release valve clockwise until it can no
longer be turned.
5. Replace the rubber stopper.
STORAgE & MAINTENANCE
1. All moving parts should be regularly oiled
2. Keep upright. The jack is not suitable for horizontal or
upside down use.
3. Keep the piston in the lowered position to protect the
hydraulics from corrosion.
4. If the jack comes into contact with moisture, wipe dry
and grease all moving parts.
5. The hydraulic pump unit is tested and sealed at the time
of manufacture. It contains no serviceable parts.
SAFETY gUIDELINES
Always use on specified jacking points, on a level surface and with a solid
foundation.
Always check that jacking points are not corroded before use.
Always ensure the load is secured against movement before lifting.
Always work under a lifted load with an additional means of support i.e.
correctly rated axle stands.
Never exceed the rated load capacity or tamper with the factory set overload
valve.
Never lean against the raised vehicle.
Never modify the jack, it is not designed to support extensions or cradles and
could become unsafe.
