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 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, o󰀨-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
• Visual inspection shall be made before each use of the portable
automotive lifting device by checking for abnormal conditions,
such as cracked welds, excessive wear, leaks, and damaged,
loose, or missing parts. The device shall be removed from
service until repaired by a Norco Authorized Service Center if
the visual inspection reveals any problems.
• A devise which is believed to have been subjected to an
abnormal load or shock should be inspected by a Norco
Authorized Service Center.
• Owners and/or operators are responsible for having the device
annually inspected by a Norco Authorized Service Center and
any defective parts, decals, or safety labels must be replaced
with Norco’s specied parts. Contact the Norco Customer
Service O󰀩ce for the location of the closest Norco Authorized
Service Center.
• Only trained operators should use this jack. It is the owner’s
responsibility to make sure all trained personnel read and
understand the product label and this instruction sheet prior to
using the jack.
• Because of potential hazards associated with this type of
device, no alterations or modications shall be made to it and
no attachments and/or adapters shall be used unless supplied
by Norco.
• Before lifting a load, 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 or components.
• This jack was designed for lifting purposes and sometimes
can be used to support the load immediately after it is lifted. If
the jack is used to support the load, two jacks must be used in
accordance with step 8 of the Operating Instructions section
of this manual. If the jack is not used to support the load
immediately after lifting, use two jack stands in accordance with
step 7 of the Operating Instructions section of this manual.
• Do not exceed rated capacity. Lift only dead weight.
• Do not exceed 200 P.S.I. input air pressure.
• Center the load on the saddle.
• Use only on hard, level surface.
• During lifting, inspect the position of the jack and its saddle in
relationship to the vehicle 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.
SETUP
1. Refer to the exploded view parts drawing for identication,
location and position of parts.
2. Insert the handle in the jack’s handle receiver and secure it to
the jack with the bolt and locknut provided. Make sure the hose
holders on the handle are facing up.
3. Install the quick disconnect of your choice in the air valve.
4. The air hose can be looped around the hose holders on the
handle for storage.
Note: Revision letters (A, B, C, D etc.) after model numbers have been omitted as they do not a󰀨ect the setup,
operating and maintenance instructions of a particular jack unless otherwise noted.

OPERATING INSTRUCTIONS
1. Become familiar with the two position air valve. Depressing the
air valve lever closest to where the shop air hose is connected to
the valve will raise the ram for lifting. Depressing the air valve lever
in the opposite direction will lower the load.
2. IMPORTANT: Before lifting load, become familiar with the
use of the jack’s ram tube, saddle tube, extension tube and pins
provided. While jack is pressurized a sudden loss of load will
cause ram tube, saddle tube and/or extension tube to rise with
su󰀩cient force to cause severe personal injury and/or property
damage. One pin is used for positioning the extension tube or the
saddle tube in the ram at the desired height. The pin should be
put through the desired hole in the extension tube or saddle tube
leaving enough pin exposure on either side for the pin to rest in the
half cutout holes in the top edge of the ram tube.
3. With the jack in the lowered position, push the jack under the
vehicle. IMPORTANT: Use the manufacturer’s recommended
lifting procedures and lifting points before lifting loads. Position the
jack at the designated lift point. Estimate the required ram travel to
raise the vehicle to the desired height. If the desired vehicle height
exceeds the entire ram travel, adjust the saddle and/or ram tube(s)
to make up the di󰀨erence.
4. Chock the vehicle’s tires that will not be lifted o󰀨 the ground
prior to lifting the vehicle and if available, apply the emergency
brake or any other method of braking.
5. Depress the air valve lever to raise the saddle close to the
designated lift point. Make sure the designated lift point is at,
parallel to the ground and free from grease, any kind of lubricant,
or debris. Do not use the saddle’s locating lugs to lift or support
the load.
6. It will be necessary to use an input air pressure of 172 P.S.I
(82990) or 186 P.S.I. (82992) to achieve the full lifting capacity.
Once the saddle is properly aligned with the designated lift point
proceed to lift the vehicle to the desired height. During lifting, inspect
the position of the jack in relation to the ground and the saddle in
relationship to the load to prevent any unstable conditions from
developing. If conditions look like they are becoming unstable,
slowly lower the load and make appropriate setup corrections after
the load is fully lowered.
7. When the vehicle is lifted to its desired height, immediately
place jack stands in the designated locations recommended by
the vehicle manufacturer to support the load. 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. Depress the air valve very slowly
to gently and slowly lower the vehicle onto the jack stands. Make
sure the vehicle is safely supported by the jack stands’ saddles
and not the locating lugs of the saddles. Inspect the relationship
of the jack stands with the ground and the jack stand columns
and saddles with the vehicle to prevent any unstable conditions.
If the conditions look unstable, depress the air valve very slightly
to gently and slowly raise the vehicle o󰀨 the jack stands. Make
the appropriate setup changes and slowly and carefully lower the
vehicle onto the jack stand saddles.
8. In some situations, this jack can be used as a jack stand
but should be used in a matched pair to support one end of a
vehicle only. Jacks used as jack stands are not to be used to
simultaneously support both ends or one side of a vehicle. In order
to use this jack as a jack stand, the second pin provided should
be put through the ram tube leaving enough pin exposed on either
side of the ram tube to rest on top of the cylinder sleeve when the
air is slowly released for lowering. The air in the cylinder should
be completely released when the pin is resting on the cylinder
sleeve. Regardless of using this jack for lifting purposes or jack
stand purposes, make sure the setup is stable. If the jacks are
used in pairs, it is important to remember the lifting of the load is
not synchronized and the operator should be very careful to lift one
jack at a time in reasonably short increments to prevent unstable
conditions.
9. After work is done, depress the air valve to raise the vehicle
just high enough to clear the jack stand saddles. Be sure load is
stable. If it is not, lower the load back onto the jack stands. Make
appropriate setup corrections and repeat the step again. Remove
the jack stands from under the vehicle being very careful not to
move the vehicle. After the jack stands are removed, very slowly
and carefully lower the vehicle down to the ground.

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.
2. The jack must be lubricated periodically in order to prevent
premature wearing of parts. A general purpose grease must be
applied to the axle where the wheels rotate and a very thin coat on
the ram. 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.
3. An air 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.
4. 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 components. Contact Norco Industries
for a replacement label if your jack’s label is not readable.
5. Inspect the jack before each use. Do not use the jack if any
component is cracked, broken, bent, shows signs of damage, or
leaks air. Do not use the jack if it has loose or missing hardware
or components, or is modied in any way. Take corrective action
before using the jack again.
6. Do not attempt to make any repairs unless you are a qualied
repair person that is familiar with this equipment.
