ASSEMBLY
1. Familiarize yourself with the jack. 2. Attach the 2 handle pieces making sure to align
the holes on both sections.
3. Line up the handle to the handle socket located
on the side of the jack. Then insert the handle
inside the handle socket.
4. Secure the handle in place inside the handle
socket. Without any vehicle on the jack. Cycle
the lift up and down several times to insure the
hydraulic system is operating properly. (Perform
the System Air Purge Procedure, Page 5, before
rst use.)

SYSTEM AIR PURGE PROCEDURE
IMPORTANT: BEFORE FIRST USE
Perform the following System Air Purge Procedure to remove any air that may have been introduced into
the hydraulic system as a result of product shipment and handling. This step is to be completed without any
weight on the jack.

(on reservior)
1. Turn release valve counterclockwise on full turn to
the open position.
2. Rapidly pump the handle 6-8 times. Leave handle
in down position to expose oil ll plug.
3. With a at blade screwdriver, push the oil ll plug
slightly to the side to purge trapped air from
system. (Use caution not to tear or puncture the
oil plug.)
4. Turn release valve clockwise to the closed
position.
5. Jack is now ready for use. Check for proper pump
action.

6
7. Before raising the vehicle double check and verify
the saddle is centered and also has full contact
with the lifting point.
RAISING THE JACK
1. Block the vehicle’s wheels for lifting stability.
Secure the load to prevent inadvertent shifting
and movement.
BEFORE USE
1. Before using this product, read the owner's manual completely and familiarize yourself thoroughly with the
product and the hazards associated with its improper use.
2. Perform the system air purge procedure. (See previous instructions for System Air Purge Procedure.)
3. Check that the pump operates smoothly before putting into service.
4. Inspect before each use. Do not use if bent, broken or cracked components are noted.
8. Pump handle to lift until saddle contacts load.
Continue to pump the jack handle to lift the
vehicle to the desired height. After lifting, support
the load with appropriately rated vehicle support
stands before working on the vehicle.
CAUTION: NEVER WIRE, CLAMP OR
OTHERWISE DISABLE THE LIFT CONTROL
VALVE TO FUNCTION BY ANY MEANS
OTHER THAN BY USING THE OPERATOR'S
HAND. USE THE HANDLE PROVIDED WITH
THIS PRODUCT OR AN AUTHORIZED
REPLACEMENT HANDLE TO ENSURE
PROPER RELEASE VALVE OPERATION. DO
NOT USE EXTENSIONS ON THE AIR HOSE
OR ON THE OPERATING HANDLE.
2. Position the jack near desired lift point.
3. Set the Parking Brake in the vehicle. 4. Refer to the vehicle manufacturer owner’s manual
to locate approved lifting points on the vehicle.
Position the jack so that the saddle is centered
and will contact the load lifting point rmly.
5. Assemble the handle, ensure that spring clips
align with slots.
6. Close the release valve by turning it clockwise
until it is rmly closed.

7
5. After removing jack from under the load, push ram
and handle sleeve down to reduce exposure to
rust and contamination.
LOWERING THE JACK
WARNING: USE EXTREME CAUTION
WHEN LOWERING THE JACK. THE JACK
HANDLE MAY TURN RAPIDLY. OPENING THE
RELEASE VALVE TOO FAST CAN CAUSE
THE JACK TO LOWER RAPIDLY. FAILURE TO
HEAD THESE WARNINGS COULD CAUSE
SERIOUS INJURY OR DEATH.
2. Remove support stands.1. Raise load high enough to allow clearance for the
jack stands to be removed, then carefully remove
jack stands.
3. Grasp the handle rmly with both hands. Securely
hold on to the jack handle so your hands do not
slip and ensure the release valve does not rapidly
lower.
4. Carefully open the Release Valve by slowly
turning the handle counterclockwise. (Do not
allow bystanders around the jack or under the
load when lowering the jack.)

MAINTENANCE INSTRUCTIONS
If you use and maintain your equipment properly, it will give you many years of service. Follow the
maintenance instructions carefully to keep your equipment in good working condition. Never perform any
maintenance on the equipment while it is under a load.
Inspection
You should inspect the product for damaged, worn, broken or missing parts (e.g.: pins) and that all
components function before each use. Follow lubrication and storage instructions for optimum product
performance.
Binding
If the product binds while under a load, use equipment with equal or a larger load capacity to lower the load
safely to the ground. After unbinding; clean, lubricate and test that equipment is working properly. Rusty
components, dirt, or worn parts can be causes of binding. Clean and lubricate the equipment as indicated in
the lubrication section. Test the equipment by lifting without a load. If the binding continues contact Customer
Service.
Cleaning
If the moving parts of the equipment are obstructed, use cleaning solvent or another good degreaser to clean
the equipment. Remove any existing rust, with a penetrating lubricant.
Lubrication
This equipment will not operate safely without proper lubrication. Using the equipment without proper
lubrication will result in poor performance and damage to the equipment. Some parts in this equipment are not
self-lubricating. Inspect the equipment before use and lubricate when necessary. After cleaning, lubricate the
equipment using light penetrating oil, lubricating spray.
• Use a good lubricant on all moving parts.
• For light duty use lubrication once a month.
• For heavy and constant use lubrication recommended every week.
• NEVER USE SANDPAPER OR ABRASIVE MATERIAL ON THESE SURFACES!
Rust Prevention:
Check rams and pump plungers on the power unit assemblies daily for any signs of rust or corrosion.
Without a load, lift the equipment as high as it goes and look under and behind the lifting points. If signs of
rust are visible clean as needed.
Grease Fittings
Some models contain grease ttings that will regularly need to be greased and lubricated.
How the Jack Operates
With release valve closed, an upward stroke of the jack handle draws oil from the reservoir tank into the
plunger cavity. Hydraulic pressure holds the valve closed, which keeps the oil in the plunger cavity. A
downward stroke of the jack handle releases oil into the cylinder, which forces the ram out. This raises the
saddle. When the ram reaches maximum extension, oil is bypassed back into the reservoir to prevent an over
extended ram stroke and possible damage to the jack. Opening the release valve allows oil to ow back into
reservoir. This releases hydraulic pressure on the ram, which results in lowering the saddle.
Storing the Jack
1. Lower the Lifting ram.
2. Place the handle in the upright position.
3. Store in a dry location, recommended indoors.
Note: If the jack is stored outdoors, be sure to lubricate all parts before and after use to ensure the jack stays
in good working condition. Always store jack in the fully retracted postion when stored in outdoor or caustic
enviroments that can cause corrosion and/or rust.
