BEFORE USE: 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. Open the release valve
counterclockwise (no more than 2 full turns). With ram fully
retracted, locate and remove the oil filler plug. Insert the handle into
the handle sleeve, then pump 6 to 8 strokes. This will help release
any pressurized air which may be trapped within the reservoir.
Ensure the oil level is just below the oil filler plug hole. Re-install the
oil filler plug. Pour a teaspoon of good quality, air tool lubricant into
the air supply inlet of the lift control valve. Connect to air supply and
operate for 3 seconds to evenly distribute lubricant. Check to ensure
that jack rolls freely (if so equipped) and that the pump operates
smoothly before putting into service. Replace worn or damaged parts
and assemblies as needed with manufacturer's authorized
replacement parts. This product is fitted to accept the popular 1/4"
NPT nipple of your choice; ensure that thread tape or compound is
used when servicing connections. Inspect before each use. Do not
use if bent, broken or cracked components are noted.
OPERATION
Lifting: Assemble two piece handle. Secure the load to
prevent inadvertent shifting and movement. Position the jack near
desired lift point. Close the release valve by turning it clockwise until
it is firmly closed.
Insert handle into handle sleeve. Pump handle or squeeze the lift
control valve until saddle contacts load. To end air operation, simply
release the grip on the lift control valve. NEVER WIRE, CLAMP OR
OTHERWISE DISABLE THE LIFT CONTROL VALVE TO FUNCTION BY
ANY MEANS OTHER THAN BY USING THE OPERATOR'S HAND. Raise
load to desired height, then immediately transfer the load to
appropriately rated support devices such as jack stands.
CAUTION: Use the handle provided with this product or
an authorized replacement handle to ensure proper release valve
operation. Do not use an extender on the air hose nor the operating
handle. When using to lift vehicle, lift only on the manufacturer's
recommended lift point and in accordance with the published
guidelines in your vehicle owners manual. Always use jack stands to
support the load immediately after lifting.
WARNING: This is a lifting device only. It is designed to lift part of the
total vehicle (one wheel or axle). Always wear safety glasses when
using this equipment. Center load on saddle before lifting. Never
work on, under or around load until it is properly supported. Transfer
the load immediately to appropriately rated jack stands. Do no use
this product for any purpose other than that for which it was
intended. It is owner's responsibility to keep labels and instructional
material legible and available. Replacement labels and manuals are
available from the manufacturer. Failure to heed these and all other
warnings pertaining to this product can result in sudden loss of lifted
load resulting in death, personal injury or property damage.

OPERATING INSTRUCTIONS
MAINTENANCE
Important: Use only a 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.
Adding Oil: With saddle fully lowered and pump position fully
depressed, set jack in its upright, level position. Remove oil filler plug.
Fill until oil is level with the filler plug hole, re-install oil filler plug.
Lubrication: A coating of light lubricating oil to pivot points, axles
and hinges will help to prevent rust and ensure that wheels, casters
and pump assemblies move freely. Periodically check the pump
piston and ram for signs of rust or corrosion. Clean as needed and
wipe with any oily cloth. NEVER USE SANDPAPER OR ABRASIVE
MATERIAL ON THESE SURFACES! When not in use, store the jack
with pump piston and ram fully retracted.
Lowering: Raise load enough to carefully remove jack stands. Insert
handle onto release valve and slowly turn handle counterclockwise,
but no more than 1/2 turn. If load fails to lower, carefully transfer
the load to another lifting device and jack stands. Carefully remove
affected jack, and then the jack stands. Lower the load, again by
slowly turning the release valve no more than 1/2 turn. After removing
jack from under the load, push ram and handle sleeve down to reduce
exposure to rust and contamination.
WARNING: Be sure all tools and personnel are clear before
lowering load. Dangerous dynamic shock loads are created by
quickly opening and closing the release valve as the load is being
lowered. The resulting overload may cause hydraulic system failure
which could cause severe personal injury and/or property damage.
