PREVENTIVE MAINTENANCE
VEHICLE JACKING
Ordinary pedestal jacks are designed ONLY to LIFT a vehicle. Once lifted,
the vehicle should be supported by other appropriate means, such as stands.
NEVER
get under, or work under, a vehicle supported ONLY by a jack.
Only work under a vehicle supported by stands and with wheels chocked.
20 TONNE HYDRAULIC BOTTLE JACK
Complies with AS/ANZ 2693:2007
Minimum height ‘lowered’ 278mm
Maximum height ‘raised’ 458mm
Your 20 tonne hydraulic jack is supplied with an ISO 15 grade Hydraulic
Oil. ALLLube Diesel Engine Oil may also be used in your hydraulic jack.
Use only oils that meet the manufacture’s recommended specifications.
Never mix different types or different specification oils.
ANY JACK SHOULD BE USED ON LEVEL FIRM
GROUND WHEREVER POSSIBLE.
NO PERSON SHOULD PLACE ANY PORTION OF THEIR
BODY UNDER A VEHICLE THAT IS SUPPORTED BY A JACK;
USE VEHICLE SUPPORT STANDS.
WHEELS NOT BEING JACKED SHOULD BE ‘CHOCKED’. NO
PERSON SHOULD REMAIN IN A VEHICLE THAT IS BEING
JACKED.
INCORRECT USE MAY RESULT IN POSSIBLE LOSS OF
LOAD, DAMAGE AND PERSONAL INJURY.
When the jack leaves the factory the oil chamber contains the correct
amount of oil. Before using for the first time, stand jack on base on a
level surface, remove the oil reservoir plug and check the oil level. The
oil level should be within 3mm of the bottom of the filler hole when the ram
is completely lowered.
Sometimes during shipment, or when changing the oil, air may get
trapped in the hydraulic system causing poor performance. To purge
any air from the system place the jack in an upright position, open
the oil reservoir plug, place a cloth over the filler hole and pump the
handle 7 to 10 times in quick succession. This will purge any air
from the system.
