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 qualied in the safe operation of the equipment and

This product is covered by a Limited Lifetime Warranty. For details
see the back cover of Norco’s product catalog.
Use only on hard, level surface.•
Before lifting a vehicle, release the parking brake, put the •
transmission in neutral, and chock the wheels at the end of the
vehicle that are not being lifted.
Do not exceed maximum capacity: 2-1/2 and 5 tons at 175 •
p.s.i. and 10 tons at 200 p.s.i.
The load must be centered on the two lift saddles of the jack so •
an equal amount of load is applied to each saddle. Lift saddles
are connected to the jack’s telescopic extendable arms and
can be extended if necessary. Remember to extend the arms
equally so the weight can be distributed equally to both lift
saddles.
These jacks were designed for lifting purposes only. Do not •
attempt to work on the vehicle until two jack stands rated equal
to or greater than the rated capacity of the jack are positioned
to support the load.
During lifting, inspect the position of the jack and its saddles 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. IMPORTANT:
A sudden loss of load will cause the main lift cylinder
and saddles to rise with sufcient force to cause severe
personal injury and/or property damage. Make sure setup
is stable.
Always lower load slowly.•
Refer to the exploded view parts drawing for identication, 1.
location and position of parts.
Install the quick disconnect of your choice in the air valve. 2.
Connect the shop air line to the quick disconnect.
These jacks are equipped with extendable arms that are 3.
secured to the jack by a bolt and nut provided. Sometimes a lower
SETUP
starting lift height is required. The jacks are shipped with the saddle
risers on the arms at the highest position but can be turned upside
down by removing the saddles and the bolt and nut that secure the
arms to the jack. Remove the extendable arms, rotate them upside
down, insert them back in the jack, secure them with the bolt and
nut provided and put the saddles in the risers. Your saddles are
now located in the lowest lift position.

OPERATING INSTRUCTIONS
Become familiar with the three position air valve. Pushing the 1.
air valve lever to the right will raise the saddles for lifting. When
the air valve lever is released it will return to the center (or neutral)
position. Pushing the air valve lever to the left will lower the saddles.
Slight pushing of the lever to the left will lower the load slowly.
IMPORTANT:2. Before lifting a load, become familiar with the
main lift cylinder and the saddles. While jack is pressurized a
sudden loss of load will cause the main lift cylinder and the saddles
to rise with sufcient force to cause severe personal injury and/or
property damage.
With the jack in the lowered position, push the jack under the 3.
vehicle. IMPORTANT: Use the manufacturer’s recommended
lifting procedures and lifting points before lifting loads. Position the
jack at the designated lift point.
Before lifting a vehicle, release the parking brake, put the 4.
transmission in neutral, and chock the wheels at the end of the
vehicle that are not being lifted.
Do not exceed 175 p.s.i. input air pressure on the 2-1/2 and 5 5.
ton capacity models and 200 p.s.i. on the 10 ton model.
Make sure the vehicle lift points are at, parallel to the ground 6.
and free from grease, any kind of lubricant, or debris. Once the jack
is positioned under that portion of the vehicle to be lifted, push the
air valve lever to the right slightly and slowly, in small increments
until the jack’s saddles come in contact with the vehicle. Make sure
the setup is stable and the saddles are adequately engaged with
the vehicle’s lift points. Do not use the saddle’s locating lugs to lift
or support the load.
Once the saddles are properly aligned and centered with 7.
the designated lift points proceed to lift the vehicle slowly to the
desired lift height. During lifting, inspect the position of the jack in
relation to the ground and the saddles 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.
Proceed pushing the air valve lever to the right until the vehicle 8.
is lifted to the desired height. You will hear the locking engagement
pawl skip over the locking blocks of the jack as the jack continues
to rise. Once the vehicle is lifted to the desired height, look down
at the bottom of the jack to see if the locking engagement pawl
is engaged with one of the locking blocks. If a locking block is
not engaged, raise the jack by pushing the air valve lever to the
right or lower the jack by pushing the air valve lever to the left so
the locking engagement pawl is engaged with the closest locking
block.
When the vehicle is lifted to its desired height, immediately 9.
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. The locking pawl must rst be
disengaged from the locking block before lowering the vehicle onto
the jack stands. Push the air valve lever slightly to the right in order
for the jack to raise the load a short distance. At the same time
use your other hand to pull up on the handle that disengages the
locking pawl from the locking block. Once the pawl disengages
from the locking block, continue to pull up on the handle and
slowly push the air valve lever to the left in order to lower the load
onto the jacks stands. Make sure the vehicle is safely supported
by the jack stands’ saddles and not the saddles’ locating lugs.
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 off the
jack stands. Make the appropriate setup changes and slowly and
carefully lower the vehicle onto the jack stand saddles.
After work is done, depress the air valve lever to the right to 10.
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 push the air valve lever to the left while simultaneously
pulling up on the locking pawl handle. Continue to pull up on the
handle until the vehicle is lowered to the ground.
PREVENTATIVE MAINTENANCE
Always store the jack in a well protected area where it will not 1.
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.
The jack must be lubricated periodically in order to prevent 2.
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 front and sides of the upright center ram tube. 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.
Maintain 25 p.s.i. tire air pressure and periodically grease the 3.
wheel ttings.
An air leak requires immediate repair which must be performed 4.
in a dirt-free environment by qualied pneumatic repair personnel
