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 qualied 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 uent 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, modied, in poor condition, leaking hydraulic uid, 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 identication, 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 ush 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.

OPERATING INSTRUCTIONS
CAUTION For Your Safety: This jack was designed for jacking purposes
only. After jacking always use safety stands to support the load before
making repairs.
1. Chock the vehicle’s tires that will not be lifted off the ground prior to lifting
the vehicle and if available, apply the emergency brake or any other method
of braking.
2. The air motor is designed to work at maximum efciency between 85 and
100 p.s.i. system air pressure. It will be necessary to have between 85 and
100 p.s.i. air pressure at the pump in order for the jack to lift its maximum
capacity. DON’T use the air hose (#19) to pull the weight of the jack as
it may cause damage to the ttings and/or air hose. DON’T neglect the
components, ttings, adapters, and hoses by rough handling of the jack.
CAUTION For Your Safety: Use jack on hard level surface, center the load
on the saddle and make sure the setup is stable. Poor operator judgement
and/or unstable setup could cause load to slip off the jack saddle and cause
personal injury and/or property damage.
3. Position the jack under the load and determine how much stroke is
required to lift the load to the required height. Any ram stroke used to raise
the extension screw saddle to the load reduces your lift stroke. The extension
screw saddle and adapters (#11) are used to make up the distance between
the saddle and the load so that you will have the most available hydraulic ram
stroke. DON’T use the ram and/or extension adapters (#11) without the
extension screw saddle as this could cause damage to the counterbore
of the ram and adapters (#11).
4. Close the release valve knob (#6) by turning it in a clockwise direction
until it stops and is snug. IMPORTANT: Use the vehicle manufacturer’s
recommended lifting procedures and lifting points before lifting loads.
5. Depress the air valve button to raise the saddle to the load. Before lifting
the load make sure the saddle is centered on the load and the setup appears
stable. If not, reposition the jack and saddle contact with the load until the
setup is stable. DON’T use the jack in unstable setup conditions as the
load could slip off the saddle and cause damage to jack components.
DON’T use the entire base assembly (#2) as a load bearing surface. The
only intended load bearing surface is directly under the hydraulic jack.
Using the entire base assembly (#2) to support the load could cause a
bent, broken or deformed base (#2) and other related jack components.
DON’T use front wheels (#8) for load bearing purposes. They are only
designed to transport and position the jack.
6. Depress the air valve button to lift the load to the desired height. During
lifting, inspect the position of the jack in relationship to the ground and the ram
in relation to the load to prevent any unstable conditions from developing. If
conditions look like they are becoming unstable, slowly lower the load and
make the appropriate setup corrections after the load is fully lowered.
7. When the vehicle or load is lifted to its desired height, immediately place
safety support stands (jack stands) in their designated locations and adjust
the stands’ support columns up as close to the designated vehicle support
points as possible. Although jack stands are individually rated, they are to be
used in a matched pair to support one end of a vehicle only. Stands are not to
be used to simultaneously support both ends or one side of a vehicle. Slowly
and carefully turn the release knob in a counterclockwise direction to gently
lower the vehicle onto the safety support stands (jack stands). Make sure
the vehicle is safely supported by the safety support stands’ (jack stands’)
saddles and not the locating lugs of the saddles. Inspect the relationship
of the safety support stands (jack stands) with the ground and the safety
support stand (jack stand) columns and saddles with the vehicle to prevent
any unstable conditions. If conditions look unstable, close the jack’s release
knob and depress the air valve to raise the vehicle off the safety support
stands (jack stands). Make the appropriate setup changes and slowly and
carefully lower the vehicle onto the safety support stand saddles. DON’T
use the jack handle assembly (#4) for purposes other than transporting or
positioning the jack. DON’T use the handle assembly (#4) as a prybar to
dislodge the jack.
8. After the work is done, close the release knob and depress the air valve
until the jack is high enough to remove the vehicle or load from the safety
support stand saddles. Be sure load is stable. If it is not, lower load back onto
safety support stands. Make appropriate setup corrections and repeat the
step again. Remove the safety support stands from under the vehicle being
very careful not to move the vehicle.
9. Turn the release knob in a counterclockwise direction very slowly and
carefully to lower the vehicle or load down to the ground. The jack may be
stored in its normal use position or in a vertical position in order to save
space. DON’T use or store the jack with the handle assembly (#4) end
of the jack pointing or angling down. Loss of uid could render the jack
inoperable. NOTE: The jack is designed with an additional air line that adds
pressure to the oil in the reservoir and forces the oil into the hydraulic pump.
The air line is vented by way of a hole located in the 1/8 NPT 90° elbow tting.
Oil from the reservoir can seep out of the hole if the jack is used or stored with
the handle assembly (#4) end of the jack pointing or angling down. Excessive
leaking from this hole could reduce the required oil level in the reservoir and
render the jack inoperable. Slight or occasional leakage from this hole should
not cause any concerns.
IMPORTANT: The oil ll level should be no higher than one inch
below the air inlet on the oil reservoir when the ram is completely
retracted. Use hydraulic jack oil or turbine oil only.

1. Always store the jack in a well protected area where it will not be
exposed to inclement weather, corrosive vapors, abrasive dust, or any
other harmful elements. The jack must be cleaned of water, snow, sand,
or grit before using.
DAILY
1. Check the condition of all moving parts and replace or repair when necessary.
2. Check the condition of the air hose and replace when necessary.
3. Check for external hydraulic uid leakage and correct the problem immediately.
MONTHLY
All checks mentioned in the “Daily Maintenance and Inspection”
procedures must be conducted.
1. Check and lightly grease the universal joint, the counter-bores of the
ram and 4” extension adapters, the telescopic ends of the 4” extension
adapters, the saddle extension screw threads and the axle. Do not lubricate
any portion of the lift saddle and make sure the saddle is free from grease,
any kind of lubricant, or debris before using the jack.
2. Remove the in-line lter and clean the debris from the lter element and
inside the lter housing.
3. Remove any signs of rust and lubricate the area to inhibit further rusting.
4. It should not be necessary to rell or top off the reservoir with hydraulic
uid unless there is an external leak. An external leak requires immediate
repair which must be performed in a dirt-free environment by qualied
hydraulic repair personnel who are familiar with this equipment. Norco
Authorized Service Centers are recommended. IMPORTANT: In order
to prevent seal damage and jack failure, never use alcohol, hydraulic
brake uid, or transmission oil in the jack. Use Chevron Hydraulic Oil
AW ISO 32 or its equivalent Unocal Unax AW 150.
5. Every jack owner is responsible for keeping the jack label clean and
readable. Use a mild soap solution to wash external surfaces of the jack
but not any moving hydraulic components.
6. Do not attempt to make any hydraulic repairs unless you are a qualied
hydraulic repair person that is familiar with this equipment.
