Product Manual

IMPORTANT NOTICE
When replacing or topping up hydraulic uid use a high grade hydraulic uid ISO10-15 or
equivalent. Do not use brake uid, alcohol, glycerin, detergent, motor oil or any other uid
preceived or claimed suitable, as the use of uids other than the hydraulic uid
recommended will cause serious damage to the internal components rendering the
jack inoperative.
TO ADD HYDRAULIC FLUID
Open the Release Valve by turning it anti-clockwise and depress the Hydraulic Ram as far
as it will go. Place the Jack on its side horizontally with the Oil Filler Cap facing upwards
and remove the cap. Fill with the recommended hydraulic uid until the uid is level with the
ller aperture. Prevent any contaminants from mixing with the hydraulic uid and entering
the jack. Replace Oil Filler Cap.
TO CHANGE HYDRAULIC FLUID
Hydraulic Fluid should be changed every twelve (12) months to maintain the Jack in peak
performance. To replace the hydraulic uid remove the Oil Filler Cap, place the Jack
on its side over a tray or bowl with the oil ller aperature facing downwards and allow the
uid to drain. This may take some time as air must enter to allow the uid to drain.
Dispose of the old hydraulic uid according to any government regulations that apply.
(Note hydraulic uid is toxic to the environment). Once drained ll the jack with hydraulic
uid as per the instruction on how ‘to add hydraulic uid’.
LUBRICATION
It is prudent to lubricate all pivoting joints on the Kojack
®
every three (3) months
with a light oil.
PREVENTING RUST
Check the Hydraulic Ram every three (3) months for signs of corrosion. If apparent clean
with an oily rag until removed. To minimise corrosion ensure the Hydraulic Ram is inserted
all the way in the jack when not in use.
GENERAL CARE AND MAINTENANCE
Do not totally unscrew or remove the release valve.
