KENNEDY
Bottle Jacks are esigne to help you work safely an efficiently. Lifting
equipment can be angerous if the correct operating an maintenance proce ures are not
followe . Operating instructions an basic safety proce ures are as follows:
1. Assemble the pump han le by fitting the smaller
tubes into the larger tube using the bolts provi e .
2. To engage the pressure piston use the slotte en
of the pump han le, turn the release valve
clockwise until tight.
3. Position the Jack un er the vehicle so that the loa
plate will be centre un er a specifie jacking point.
4. Insert the pump han le into the piston assembly &
pump the han le to raise the loa .
5. Once the loa has been raise to the require
height, use an a itional support (i.e. correctly
rate axle stan s) before continuing work.
6. To lower the vehicle, raise the jack in or er to
remove the a itional supports. Insert the slotte
en of the pump han le into the release valve &
turn it anti-clockwise no more than one complete
turn. The spee at which the vehicle is lowere can
be controlle by how far the release valve is turne .
REFILLINg ThE OIL RESERVOIR
1. Only refill the oil with the jack in an upright position.
2. The Jack's piston shoul be in the lowest position.
3. Remove the rubber stopper from the cylin er housing.
4. Using hy raulic oil ISO VG.22/32, fill to the lower rim of
the stopper hole.
5. Replace the rubber stopper an blee the hy raulic
system of air.
BLEEDINg ThE SYSTEM
1. Using the slotte en of the pump han le turn the
release valve anti-clockwise no more than one
complete turn.
2. Remove the rubber oil stopper from the cylin er
housing.
3. Insert the pump han le into the piston assembly &
pump the han le several times to force out any air.
4. Turn the release valve clockwise until it can no
longer be turne .
5. Replace the rubber stopper.
STORAgE & MAINTENANCE
1. All moving parts shoul be regularly oile
2. Keep upright. The jack is not suitable for horizontal or
upsi e own use.
3. Keep the piston in the lowere position to protect the
hy raulics from corrosion.
4. If the jack comes into contact with moisture, wipe ry
an grease all moving parts.
5. The hy raulic pump unit is teste an seale at the time
of manufacture. It contains no serviceable parts.
