KENNEDY

thoroughly recommends reading these instructions before using

the Hydraulic Equipment even if you have used Hydraulic Equipment before.

Reading these instructions carefully and understanding them fully will enable you

to perform collision repair on a vehicle correctly and will prevent injury to yourself

or someone else as well as prevent damage to the vehicle and equipment.

SAFETY GUIDELINES

GENERAL

lAlways use approved eye and face protection. If necessary also wear protective gloves.

lAlways keep children and unauthorised people away from the work area.

lAlways store in a secure, dry place, out of reach from children.

lAlways stay alert at all times.

lAlways wear proper clothing.

lAlways inspect tools before each use.

lAlways keep tools away from heat.

lAlways ensure tools are used by qualified mechanics who are familiar with its use.

lever operate tools if any parts are missing, damaged or faulty.

lever operate tools when you are tired, under the influence of alcohol, drugs or intoxicating

medication.

lever force tools.

lever overreach.

lever stand on tools.

lever allow tools to get wet or remain in a damp environment.

HYDRAULIC EQUIPMEN

lAlways replace the dust caps back onto the couplings after use.

lAlways refill with hydraulic fluid only, making sure no dirt gets into the hydraulic system. Do

not mix different types of oil or use brake fluid.

HAND PUMPS

lAlways bleed the hand pump before use, to release any trapped air.

lAlways release the pressure from the pump when not in use.

lever modify in any way.

lever carry the pump by the hose.

PUSH & PULL RAMS

lAlways make sure the lift point is stable and properly centred on the ram.

lever exceed the the rated capacity.

lever work under loads which are supported only by hydraulic equipment. Use additional

mechanical supports.

lever use extreme heat to disassemble.

HOSES

lAlways inspect the hose each time before use.

lAlways replace hydraulic hoses within 10 years, even if no defects are detected.

lAlways ensure all hose connections are tightened and are not leaking. Do not overtighten the

hose, as this could cause premature thread failure or high pressure fittings to split at

pressures lower than their rated capacities.

lever grasp a leaking pressurised hose with your hands. The force of escaping fluid could

cause serious injury.

lever drop any heavy objects onto the hose, allow it to kink, twist, curl, crush or bend so

tightly that the fluid flow within the hose is blocked or reduced.

lever subject the hose to potential hazards such as fire, sharp surfaces, extreme heat or

cold.

lever allow the hose to come into contact with corrosive materials, such as creosote-

impregnated objects and some paints as hose deterioration can occur.

Use an approved, high grade pipe thread sealant to seal all hydraulic connections. PTFE Teflon tape (KE -

being pinched by the coupler and broken off inside the pipe end. Any loose pieces of tape could travel

through the system and obstruct the flow of fluid or cause the jamming of precision fitted parts.

OPERATING

APPLICATIONS AND LOAD CAPACITY

USE:

To pressurise the hydraulic hand pump, turn the release valve on

the side of the pump clockwise to close the valve. Then pump

the handle up and down.

To release pressure, open the valve by turning the release valve

anti-clockwise.

The hand pump can be used in any position. When using the

hand pump in a vertical position, always ensure that the hose

end is facing downwards.

Adding two extension rods to

the hydraulic ram will make

the capacity reduce by 50%.

When the load is off centre the

capacity will be reduced by

a further 50% and each

additional single extension will

reduce the capacity by

a further 50%. If connecting

more than two extensions

together, ensure that the short

extension is positioned the

furthest away from the

hydraulic ram.

CARE & MAINTENANCE

CHECKING & FILLING THE OIL RESERVOIR:

1. Place the hydraulic hand pump on a level surface and disconnect any

attachment from the end.

2. Always follow the precautions advised by the oil manufacturer.

3. Open the pressure release valve.

4. Remove the filler plug from the cylinder. The oil should be within

15mm from the top of the reservoir.

If necessary, fill with hydraulic oil ISO VG.22.32 until the oil is within

15mm from the top of reservoir. DO OT USE BRAKE FLUID.

5. Pump the handle 5 or 6 times to expel air.

6. Screw on the filler plug.

Avoid mixing different grades of oil. After long periods of use, the oil should be replaced with new oil.

LUBRICATING:

Use light oil on all moving parts.

WHEN NOT IN USE:

Wipe clean with a slightly oiled cloth.

Store the hand pumps with the release valve open.

Store the rams in a vertical position with the rod end down in a dry, well protected area, where they will not be

exposed to corrosive vapours, dust or other harmful elements.

When a ram has not been used for 3 months, it should be connected to a pump and be fully extended and then

retracted to lubricate the cylinder walls, thereby reducing the potential for rust formation.

Make sure that the threaded dust cap plugs are put on to the ends of any hose, hydraulic rams and

accessories, to avoid dirt from entering the system.

BLEEDING THE SYSTEM:

Air can accumulate in the hydraulic system during the initial setup or after prolonged use, causing the ram to

respond slowly or in an unstable manner. To remove the air, please follow these steps.

1. Place the ram at a lower level than the pump, with the piston end pointing down.

2. Extend and retract the ram several times without putting a load on the system. Air will be released into the

pump reservoir.

3. With the ram fully retracted, the pump sitting level and no pressure in the hydraulic system, remove the

pump’s filler screw.

4. Pump the handle 5 or 6 times to bleed air out of the system.

5. Close the pressure release valve.

6. Replace the filler plug screw.

SETTING UP

Remove the dust covers from the hydraulic ports. Clean the area around these ports if necessary. Clean all

hose ends, couplers and union ends. Connect all hose assemblies to the pump and cylinder (sealing tape may

have to be used - See REPAIRS on page 6 for further information). Tighten securely but do not over tighten.
