SETUP • OPERATING • MAINTENANCE INSTRUCTIONS
BEFORE USING THIS DEVICE, READ THIS MANUAL COMPLETELY
AND THOROUGHLY, UNDERSTAND ITS OPERATING PROCEDURES,
SAFETY WARNINGS AND MAINTENANCE REQUIREMENTS. FAILURE
TO DO SO COULD CAUSE ACCIDENTS RESULTING IN SERIOUS OR
FATAL PERSONAL INJURY AND/OR PROPERTY DAMAGE.
The use of portable automotive lifting devices is subject to certain hazards
that cannot be prevented by mechanical means, but only by the exercise
of intelligence, care, and common sense. It is therefore essential to have
owners and personnel involved in the use and operation of equipment who
are careful, competent, trained, and qualified in the safe operation of the
equipment and its proper use. Examples of hazards are dropping, tipping, or
slipping of motor vehicles or their components caused primarily by improperly
securing loads, overloading, off-centered loads, use on other than hard level
surfaces, and using equipment for a purpose for which it was not designed.
It is the responsibility of the owner to make sure all personnel read this
manual prior to using this device. It is also the responsibility of the device
owner to keep this manual intact and in a convenient location for all to see
and read. If the manual is lost or not legible, contact Norco Industries, Inc.
for a free replacement. If the operator is not fluent in English, the product
and safety instructions shall be read to and discussed with the operator in
the operator’s native language by the purchaser/ owner or his designee,
making sure that the operator comprehends its contents.
WARRANTY
This product is covered by a Limited Lifetime Warranty. For details see the
back cover of Norco’s product catalog.
IMPORTANT: READ THESE INSTRUCTIONS BEFORE OPERATING
WARNING
• Before lifting a vehicle, refer to the vehicle’s service manual or inquire
from the vehicle manufacturer the recommended jack lifting points and
jack stand support surfaces on the vehicle chassis.
• Inspect the jack before each use. Do not use the jack if it is damaged,
altered, modified, in poor condition, leaking hydraulic fluid, or unstable
due to loose hardware. Take corrective action before using the jack.
• This jack was designed for lifting purposes only. Do not attempt to work
on the vehicle until jack stands rated equal to or greater than the rated
capacity of the jack are positioned to support the load.
• Do not move or dolly the vehicle while on the jack.
• Do not use the jack beyond its rated capacity. Lift only dead weight.
• Do not exceed 100 P.S.I. input air pressure.
• Center load on saddle. Be sure setup is stable. Off-center loads can
cause jack failure and/or loss of load.
• Use the jack on a hard level surface.
• Do not modify the jack or use saddle adapters or saddle extenders
unless approved or supplied by Norco.
• Do not position any part of your body directly above the lifting saddle
when operating the jack.
• When activating the jack with no load, the ram raises quickly, therefore
never put your hands or any other part of your body between the lifting
saddle and the load.
• Do not use the jack in horizontal or angular positions.
• Always lower the jack slowly and carefully.
SETUP
1.
Refer to the exploded view parts drawing for identification, location and
position of parts.
2.
The jack is shipped in two cartons. Remove the handle assembly and
jack from their respective cartons.
3.
An allen socket set screw secures the release collar (#21) to the
release shaft (#5) on the handle assembly (#4). Back the set screw off so
the collar (#21) freely slides up and down on the release shaft (#5).
4.
A universal joint (#18) is assembled to the release valve on the hydraulic
jack. The free end of the universal joint (#18) includes a set screw which
must be removed so the release shaft (#5) on the handle assembly (#4)
can be slipped into it. Set screw will be installed in step 7.
5.
Remove the hex head bolt (#15), and jam nut (#14) from the handle
receiver of the jack base.
6.
Install the handle assembly (#4) into the handle receiver while at the
same time feeding the release shaft (#5) into the universal joint (#18). Align
the hole in the handle assembly (#4) with the hole in the handle receiver
and secure with the hex bolt (#15), and jam nut (#14) provided.
7.
Rotate the release shaft (#5) so the hole at the bottom of the shaft
aligns with the set screw hole in the universal joint (#18). Secure the
release shaft (#5) in the universal joint (#18) by installing and tightening
the allen socket set screw that was previously removed.
8.
Rotate the release shaft knob (#6) in a clockwise direction until the
release valve stops and is snug. Now rotate the release valve knob (#6)
two full turns in the counterclockwise direction. Slide the release collar
(#21) up and flush against the lower guide tab on the handle assembly
(#4). Secure the release collar (#21) in this position by tightening the allen
socket set screw.
NEVER
open the release valve more than two full turns
when applying air to the jack or for any other reason except repair. Make
sure air is disconnected before removing the release valve.
NOTE:
Allen
socket set screws will not back themselves out of the release collar (#21)
or universal joint (#18) if installed and tightened with penetrating thread
locker.
9.
The end of the air hose (#19) is supplied with a standard 3/8 NPT
male quick-disconnect nipple. Make sure your female quickdisconnect is
compatible or change it to meet your needs.
PURGING AIR FROM THE HYDRAULIC SYSTEM
a.
Sometimes the jack is shipped, handled or stored in a position other
than vertical. This may cause air to be trapped in the pump and
cause the ram to raise in increments instead of a smooth travel. To
eliminate this condition perform the following steps:
b.
Purge the air by turning the release valve knob (#6) two full turns in
a counterclockwise direction from its closed position.
c.
Then depress the air valve button for about 10 seconds.
d.
Turn the release valve knob (#6) in a clockwise direction until it stops
and is snug. The jack should function properly. Repeat steps “a”
through “b” until the jack’s operation is satisfactory.
