Enerpac Automotive Air Bottle Jacks are designed for lifting, but not
sustaining, loads ranging from up to 12 through 50 tons depending
on the rated capacity of the jack. They can be used vertically or
angled to 5° from vertical position. After lifting, loads must be
IMMEDIATELY supported by appropriate means. Each model is
suitable for use in an appropriately rated and designed vertical or
bench press structure. These jacks are not recommended for use in
lifting or positioning hoses and/or other building structures. These
jacks comply with ASME / ANSI Standards. For air actuated use,
ensure that your air source can dedicate 7.8 CFM @90-175 psi to
each jack operated. To ensure dependable, troublefree operation an
air dryer and oiler is recommended.

DANGER: To avoid personal injury keep hands
and feet away from jack and workpiece during
operation.
WARNING: Do not exceed equipment ratings. Never
attempt to lift a load weighing more than
the capacity of the jack. Overloading causes
equipment failure and possible personal injury.
Never set the relief valve to a higher pressure than
the maximum rated pressure of the pump. Higher
settings may result in equipment damage and/or
personal injury.
CAUTION: Avoid damaging air hose. Avoid sharp
bends and kinks when routing air hoses. Using a
bent or kinked hose will cause severe back-pressure.
Sharp bends and kinks will internally damage the hose
leading to premature hose failure.
Do not drop heavy objects on hose. A sharp
impact may cause internal damage to hose wire
strands. Applying pressure to a damaged hose
may cause it to rupture.
IMPORTANT: Do not lift hydraulic equipment by the
hoses or swivel couplers. Use the carrying handle or
other means of safe transport.
CAUTION: Keep hydraulic equipment away from
flames and heat. Excessive heat will soften packings
and seals, resulting in fluid leaks. Heat also weakens
hose materials and packings. For optimum performance do
not expose equipment to temperatures of 65°C [150°F] or
higher. Protect hoses and jacks from weld spatter.
DANGER: Do not handle pressurized hoses. Escaping
air under pressure can penetrate the skin, causing
serious injury. If oil is injected under the skin, see a
doctor immediately.
WARNING: BE SURE SETUP IS STABLE BEFORE
LIFTING LOAD. Jacks should be placed on a
flat surface that can support the load.
Avoid situations where loads are not directly centered
on the jack plunger. Off-center loads produce
considerable strain on jack and plungers. In addition,
the load may slip or fall, causing potentially dangerous results.
Distribute the load evenly across the entire saddle
surface. Always use a saddle to protect the plunger.
IMPORTANT: Hydraulic equipment must only be
serviced by a qualified hydraulic technician. For
repair service, contact the Authorized ENERPAC
Automotive Service Center in your area. To protect your
warranty, use only ENERPAC oil.
WARNING: Immediately replace worn or damaged
parts by genuine ENERPAC Automotive parts.
Standard grade parts will break causing personal
injury and property damage. ENERPAC Automotive parts are
designed to fit properly and withstand high loads.
3.0 PREOPERATION
1. To prevent hydraulic fluid loss during shipment, the oil
filler plug is closed at the factory.
2. Occasionally, hydraulic jacks become airbound during
shipment and will not function properly.
3. Thoroughly lubricate all moving parts of the jack.
a. Raise the saddle to full height by closing release
valve and pumping handle.
b. Lubricate the surface of the ram as well as all moving
parts in the handle and lifting mechanism.

4.0 OPERATION
4.1 Lifting Load
1. Assemble three-piece handle. Assure that spring clips
align with slots.
2. Secure the load to prevent inadvertent shifting and
movement.
3. Position the jack near desired lift point.
4. Close the release valve by turning it clockwise until it is
firmly closed.
5. Secure your load with 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 points and in accordance with the
published guidelines in your vehicle owner's manual. Always
use jack stands to support the load immediately after lifting.
6. Insert and secure 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.
7. Raise load to desired height, then immediately transfer
the load to appropriately-rated support devices such as
jack stands.
WARNING: This is a lifting device only. It is designed
to lift part or the total vehicle (one wheel or axle). It
is the owner's responsibility to keep labels and
instructional material legible and available. Replacement
labels and manuals are available from Enerpac Automotive.
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.
4.2 Lowering Load
1. Raise load enough to carefully remove jack stands.
2. 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.
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.
3. After removing jack from under the load, push ram and
handle sleeve down to reduce exposure to rust and
contamination.
5.0 MAINTENANCE
Important: To protect your warranty use only genuine
Enerpac Hydraulic oil. Improper fluid can cause premature
failure of the jack and the potential for sudden and
immediate loss of load.
5.1 Adding Oil
1. With saddle fully lowered and pump piston fully
depressed, set jack in its horizontal, level position.
Remove oil filler plug.
2. Fill until oil is level with the filler plug hole. Reinstall oil
filler plug.
5.2 Changing Oil
For best performance and longest life, replace the
complete fluid supply at least once per year.
1. With saddle fully lowered and pump piston fully
depressed, remove the 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 genuine Enerpac hydraulic oil. Reinstall oil
filler plug.
5.3 Lubrication
A coating of light lubricating oil to pivot points, axles and
hinges will help to prevent rust and assure 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 an oily cloth.
NEVER USE SANDPAPER OR ABRASIVE MATERIAL
ON THESE SURFACES!
5.4 Rust Prevention
Check ram every 3 months for any sign of rust or corrosion.
Clean as needed and wipe with an oil-saturated cloth.
NOTE: When not in use, store the jack with pump
piston and ram fully retracted.
