1. Safety Regulations
1.1 Warnings
Failure to follow all of these safety instructions can
lead to severe injury or death from a sudden loss of
the load. Contact the manufacturer at the numbers or
address printed on the back cover of this manual if
you have any questions.
Before using this jack, be sure you have read and
understood all of the instructions and warnings on the
on product labeling and in this owner’s manual. See
the section entitled “OWNER AND/OR OPERATOR
RESPONSIBILITIES” on page 6 of this manual for
more information.
Inspect the jack before each use. The jack must be
removed from service if damage is detected or if the
jack is subjected to an abnormal shock or load. See
page 10 of this manual for proper “INSPECTION –
BEFORE EACH USE.”
Inspect the work area before each use. Make sure
the jack and vehicle are located on a hard, level
surface capable of supporting the load.
Identify appropriate vehicle lift points before using
the jack. Lift only on areas of the vehicle specified by
the vehicle manufacturer. The lift point must be strong
enough to sustain the lifting force without damage to
the vehicle. The jack must remain in direct contact
with the floor and the lifting pad must be in direct
contact with the vehicle.
Make sure the lift point is securely cradled in the
center (i.e., between the “saddle ears”) of the lift post
saddle— Never lift a load with it resting on top of a
saddle ear of the lift post saddle. Always use the
factory-supplied lift post saddle to raise a load and
never use blocks or cribbing devices in conjunction
with this jack (only adapters and/or attachments
supplied by the manufacturer for this particular jack
can be used). Never place a hand or any other body
part between lift post saddle and vehicle.
Do not exceed the maximum lift height. Never use
more than one optional extension adapter with this
jack.
After lifting the vehicle, never allow any part of your
body to pass under it (and never begin work) until the
ram of the jack is properly pinned and the air is
exhausted. If the air is not exhausted and the jack is
not properly pinned, the jack may rise or drop
suddenly when a heavy object is removed from or
placed on the vehicle, which could cause dangerous
tilting or toppling of the vehicle.
Always use the jack as intended. Never modify or
alter the jack. If this jack does not have sufficient
capacity to lift a load, use a different jack with
adequate capacity. Never attempt to reposition or
rotate the jack or move, dolly, or drive the vehicle
while it is raised. Never use this jack to lower or
support a vehicle if the vehicle was raised using
another lifting device or devices. Do not attempt to
raise a partially-filled tanker or transport containing an
unrestrained load as a sudden load shift could cause
a dangerous tilting or toppling of the vehicle. Never
throw the jack or allow it to fall from an elevated
position, such as from a truck bed.
CAUTION - Use of this jack around corrosive
materials, such as chlorides, will damage inside the
cylinder, causing leakage. SUCH USE INVALIDATES
WARRANTY.
Make sure the load does not exceed the rated
capacity of the jack. The maximum capacity of the
jack is printed on the capacity tag located on the
head plate of the jack.
