WARNING

!

To avoid personal injury and/or property damage:

• Read, understand and follow all printed materials
provided with and on this jack.

• This is a lifting device only! Never work on, under, or
around a load supported only by a hydraulic jack.

• Immediately support the lifted load with appropriately
rated mechanical means.

• Use only on hard, level surfaces capable of
sustaining rated capacity loads.

• Center load on saddle.

• No alteration shall be made to this device. Use only
attachments, adapters and accessories provided by
the manufacturer.

• Be alert and sober when using this product! Never
operate this equipment when under the influence of
drugs or alcohol.

• Use only high grade hydraulic jack oil in this product.

• Always use a calibrated means of determining how

much force is being applied by this product. Never
exceed the rated capacity of the jack.

PRODUCT DESCRIPTION

This product is designed to lift, position, or move, but not
sustain, rated capacity loads. It is not designed to be used

as a stand-alone device. Any load lifted, positioned, or
otherwise moved by this device, must immediately be
supported by appropriately rated mechanical means. A wide
variety of applications exist for this category of product.
Special skill, knowledge and training may be required for a
specific task and this product may not be suitable for all
jobs listed. Unsuitable applications include applications that
call for a device to lift, position, move or support persons,
an i mal s , h a zar dous materi als, mob ile home s an d
dwellings in general, mirrors, plate glass or to connect/
secure hatche s, comp on ents, and materials b etween
bulkheads. The user ultimately must make the decision
regarding suitability of the product for any given task and
therefore accept responsibility for that decision.

BEFORE USE

Before using this jack, ensure that the intended load

!

contact point is able to withstand the load applied by this jack.

1. Before u sing th is prod uct, read the owner’s m anual
completely and familiarize yourself thoroughly with the
product, its compone nts, and recognize the hazards
associated with its use.

2. To familiarize your self with basic op eration, use the
operating handle to engage and turn the release valve:

a. Clockwise until firm resistance is felt to further thread
engagement. This is the ‘CLOSED’ release valve
position used to pressurize the hydraulic fluid and
raise the ram plunger.

b. Counter-clockwise, but no more than 1/2 turn from the

closed position. This is the ‘OPEN’ release valve position

used to lower the ram plunger.

3. Check that the pump operates smoothly before putting into
service. Replace damaged or missing parts with factory
authorized replacement parts only. Repair of this product
may require special skills and knowledge and should only
be attempted by a factory authorized service center. Contact
the manufacturer or distributor of this product for a list of
factory authorized service centers. Lubricate as instructed
in Maintenance Section.

Bleeding/ Venting Trapped Air

With the release valve in the OPEN position (2b above) and
with saddle fully lowered, locate and remove the oil filler plug.
Insert the handle into the handle sleeve; then pump 6 to 8 full
strokes. This will help release any pressurized air which may
be trapped within the reservoir. Oil level should be even with
the bottom of the oil filler plug hole. Reinstall the oil filler plug.

Use of this device may require special skills and
knowledge. Read, understand, and follow all printed materials
provided with and on this device before use.

OPERATION

!

Use of this device may require special skills and
knowledge. Re ad, understand, and follow all printed
materials provided with and on this device before use.

Raising the Ram Plunger

1. Locate and close release valve by turning handle

clockwise until firm resistance is felt to further thread

engagement.

2. Pump until load reaches desired height.

secure with appropriately rated mechanical devices. It is

recommended you follow the load with cribbing and

blocking where practical.

!

Never allow personnel to work or pass under a load

until the load is secured by cribbing, blocking, or other
mechanical means.

Lowering

!

Make certain that all personnel are clear of the load
before lowering. Control the rate of descent of the load at all
times. The more you open the release valve, the faster the
load descends.

1. Use the manufacturer's provided operating handle to

engage and slowly turn the release valve counter-

clockwise, but no more than 1/2 turn.

!

If the ope rati ng h and l e is da mag ed, operate s
abnormally, or will not positively engage the release valve,
im medi atel y d i sco n tin u e u s e o f the j ack unt il a
manufactu re r's replacement h andle assembly can be
acquired.

2. Push ram down and handle sleeve in to reduce exposure

to rust and contamination after removing jack from under

load.

Immediately

MAINTENANCE

Important: Use only good grade hydraulic jack oil. Avoid

mixing different types of fluid and NEVER use brake fluid,
turbine oil, transmission fluid, motor oil or glycerin. Improper
fluid can cause premature failure of the jack and the potential
for sudden and immediate loss of load. W e recommend
Mobil DTE13M or equivalent.

Adding

1. W ith saddle fully lowered set jack in its upright, level
position. Locate and remove oil filler plug.

2. Fill with oil even with the bottom of the oil filler hole.
Reinstall the oil filler plug.

Changing oil

For best performance and longest life, replace the complete
fluid supply at least once per year.

1. W ith saddle fully lowered set jack in its upright, level
position. Locate and remove oil filler plug.

2. Lay the jack on its side and drain the fluid into a suitable
container.

Note: Dispose of hydraulic fluid in accordance with local
regulations.

3. Fill with oil even with the bottom of the oil filler hole. Reinstall
the oil filler plug.

Lubrication

A periodic coating of light lubricating oil to pivot points will
help to ensure that pump piston linkages move freely.

Note: Never apply oil to saddle.

Cleaning

Periodically check the pump piston and ram plunger, and
saddle for signs of rust or corrosion. Clean as needed and
wipe with a clean, oil soaked rag.

Note: Never use sandpaper or abrasive material on these
surfaces !

Storage

Store the jack with pump piston, ram plunger/saddle
lowered and release valve open, but never more than 1/2
turn. This will help prevent rust and corrosion to those critical
surfaces.
