MODEL 842

FOR YOUR SAFETY

Read all instructions, warnings and cautions carefully. Follow all safety precautions to avoid personal injury

or property damage during system operation. Jackco cannot be responsible for damage or injury resulting

from unsafe product use, lack of maintenance or incorrect product and/or system operation. Contact Jackco

when in doubt as to the safety precautions and operations.

Failure to comply with the following cautions and warnings could cause equipment damage and personal

injury.

• Stay clear of loads supported by hydraulics.

A cylinder, when used as a load lifting device,

should never be used as a load holding device.

After the load had been raised or lowered,

it must always be blocked mechanically.

• Do not exceed equipment rating never attempt

to lift a load weighing more than the capacity

of the cylinder. Overloading causes equipment

failure and possible personal injury. The

cylinders are designed for a maximum pressure

of 10,000 psi. Do not connect a jack or cylinder

to a pump with a higher pressure rating.

• The system operating pressure must not

exceed the pressure rating of the lowest

rated component in the system. Install

pressure gauges in the system to monitor

o p e r a t i n g p r e s s u r e . I t i s y o u r w i n d o w

to what is happening in the system.

• Only use hydraulic cylinders in a coupled

system. Never use a cylinder with

unconnected couplers. If the cylinder becomes

extremely overloaded, components can fail

catastrophically causing severe personal injury.

• BE SURE SETUP IS STABLE BEFORE

LIFTING LOAD.

Cylinders should be placed on a flat

surface that can support the load. Where

applicable, use a cylinder base for added

stability. Do not weld or otherwise modify the

cylinder to attach a base or other support.

• Avoid situations where loads are not directly

centered on the cylinder plunger. Off-center

loads produce considerable strain on cylinders

and plungers. In addition, the load may slip

or fall, causing potentially dangerous results.

• Immediately replace worn or damaged parts

genuine JACKCO parts. Standard grade parts

will break causing personal injury and property

damage. JACKCO parts are designed to fit

properly and withstand high loads.

• To avoid personal injury keep hands and feet away

from cylinder and work piece during operation.

• 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. Do no remove relief valve.

• Do not handle pressurized hoses. Escaping oil

under pressure can penetrate the skin, causing

serious injury. If oil is injected under the skin, see a

doctor immediately.

• Avoid damaging hydraulic hose. Avoid sharp bends

and kinks when routing hydraulic hoses. Using a

bent or kinked hose will cause severe backpressure.

Sharp bends and kinks will internally damage the

house 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.

• Do not lift hydraulic equipment by the hoses or

swivel couplers. Use the carrying handle or other

means of safe transport.

• Keep hydraulic equipment away from flames and

heat. Excessive heat will soften packing and seals,

resulting in fluid leaks. Heat also weakens hose

materials and packings. For optimum performance

do not expose equipment to temperatures of 150°F

or higher. Protect hoses and cylinders from weld

spatter.

• Hydraulic equipment must only be serviced by a

qualified hydraulic technician. For repair service,

contact JACKCO Inc. To protect your warranty, use

INSTRUCTION

PRODUCT DESCRIPTION

-10,000 PSI AIR Hydraulic Pump designed to operate @90-120 PSI air source.

-This equipment allows quick displacement of hydraulic uid up to 1600 c.c/97 cu.in..

-Foot pedal design delivers a smooth, controllable flow to and from the intended

application.

SPECIFICATION

Capacity Pump Size (L x W x H) Usable Volume Oil Oil Outlet Size

10,000 PSI 10” x 5.6”x 8.3” 1600c.c./97 cu.in. 3/8 NPT

IMPORTANT

1. Check for leaks in the system and repair as needed. Before repairs are made, disconnect

air inlet and hydraulic connection, then depressurize reservoir. Do so simply by depressing

the pedal for a few seconds.

2. Replace worn / damaged parts and assemblies with original new parts.

3. Use adequate eye protection when operating or near this equipment.

4. Check connections before use.

OPERATION

1. Pull up the air-vent before use.

2. Connect to a hydraulic cylinder, then to air source of at least 100 PSI, and then depress

foot pedal slowly until motor starts to move.

3. Operate pump until desired position is reached. To stop, release pressure on the pedal.

4. To retract, simply press down on the “RELEASE” portion of the foot pedal.

AIR REMOVAL

Removing air from the hydraulic system will help the cylinder to advance and retract smoothly.

Pump with Single-Acting Cylinder

• Position pump at higher elevation than cylinder.

• Position cylinder with plunger end down (up if using pull cylinder)

• Operate pump to fully extend the cylinder (retract if using pull cylinder)

• Depress release valve to retract cylinder (extend if a pull cylinder). This will force the trapped

air to move up to the pump reservoir.

• Repeat the above steps as necessary.

• Add oil if necessary.

• Return vent/ll cap to operating position.

How to ll the reservoir

1. Disconnect hydraulic coupler from application, remove air supply from pump.

2. Remove the vent /oil ller plug.

3. Fill reservoir to within ½ inch of the opening.

4. Wipe off any spilled uid and install oil ller plug.

NOTE:

Use only quality hydraulic fluid. Never use brake fluid, transmission fluid, motor oil

etc. Use of other than quality hydraulic oil will void the warranty and damage the

equipment.

AIR SUPPLY

• To obtain maximum performance and rated hydraulic pressure, air pressure should be 100 psi

minimum.

• To insure trouble-free performance, your air supply equipment should be equipped with an air

lter/dryer and the compressor tank should be drained of water everyday.

LUBRICATION

• To insure long service life, add a few drops of # 30 oil into the air inlet once a week.

MAINTENANCE

Use only recommended JACKCO hydraulic oil with theses pumps to promote long pump life and

protect your warranty. Contact your JACKCO representative for more information on these products

and their applications.

KEEPING OIL LINES CLEAN

When coupler halves are disconnected, always screw on dust caps. Use every precaution to guard

unit against entrance of dirt because foreign matter may cause pump, cylinder or valve failure.

CHANGING THE OIL

• Drain all oil and rell with clean JACKCO hydraulic oil every 12 months, if pump is used in dirty

environments, change the oil more often.

• Remove vent/ll cap or plug from reservoir

• Tilt pump to drain out old oil.
