 PROFESSIONAL LIFTING EQUIPMENT

®

BEFORE USING THIS JACK, 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 floor service jack 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.

• 

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. The jack must be free to 

roll and reposition itself while lifting or lowering the vehicle.

• 

Do not modify the jack or use saddle adapters or saddle 

extenders unless approved or supplied by Norco.

• 

Always lower the jack slowly and carefully.

SETUP

1. 

If your jack is equipped with a two-piece handle, fit the handle 

halves together and secure them by tightening the bolt and nut 

provided.

2. 

Using an open end or socket wrench, remove the hexagonal 

head screw located on top of the handle receiver so the handle 

can be inserted all the way.

3. 

Insert the handle in the handle receiver making sure the 

configuration at the end of the handle fits into the slotted position 

of the mechanism inside the handle receiver. The outside groove 

at the bottom of the handle should align with the screw hole in the 

handle receiver.

4. 

Install the hexagonal head screw in the screw hole in the 

bottom of the handle receiver and tighten. This will secure the 

handle in the handle receiver allowing you to maneuver the jack. 

The hexagonal head screw will not bottom out on the handle thus 

allowing you to  rotate the handle in either direction for activation 

of the release valve to either raise or lower the jack.

5. 

Sometimes air gets trapped in the hydraulic system during 

shipment. An air bound hydraulic system feels spongy when 

pumped and sometimes the jack will not pump full incremental 

strokes.

PURGING AIR FROM THE HYDRAULIC SYSTEM
a. 

Open the release valve by turning the handle in a 

counterclockwise direction two full turns.

b. 

Pump the handle ten full strokes.

c. 

Close the release valve by turning the handle in a clockwise 

direction until tight.

d. 

Pump the jack until the lift arm is extended to maximum 

height.

e. 

If the condition remains, repeat steps “a” through “d” until all 

the air is purged from the system.

Note: Revision letters (A, B, C, D etc.) after model numbers have been omitted as they do not affect the setup, 

operating and maintenance instructions of a particular jack unless otherwise noted.
