12. Bolt the press to the floor if it is to be used on bulky or unstable items.

HYDRAULIC SAFETY

DANGER! Seek immediate, professional medical treatment if hydraulic fluid

penetrates your skin. It may feel like a pricking or sting. Do not wait for the

appearance of symptoms. A toxic reaction will occur from the exposure.

Delay in treatment can lead to amputation or death.

Inform the medical staff that you have a hydraulic fluid penetration injury as soon as

you arrive at the medical facility. The symptoms are tissue swelling near the wound

that can burst through the skin. This follows with throbbing and numbness in the

tissue. Bring the Material Safety Data Sheet for the hydraulic fluid with you to the

medical facility.

1. Do not touch or handle hydraulic hoses or components while under

pressure. A pinpoint hole may inject hydraulic fluid into your body (See

Danger! above).

2. Hydraulic oil under pressure is hot and can burn you.

3. Hydraulic components require regular inspection. Release all pressure

from the system before you inspect it. Replace damaged hydraulic parts

with identical manufacturer's components.

4. Do not attempt makeshift repairs to a hydraulic system. Such repairs can

fail suddenly and create a hazardous condition.

5. Never exceed the hydraulic system’s load capacity (see Specifications).

6. Do not adjust the hydraulic system’s relief setting.

7. Hydraulic fluid escaping under pressure has sufficient force to penetrate

your clothing and skin.

8604589 12 Ton Hydraulic Shop Press V 4.1

6 For technical questions call 1-800-665-8685

a. Always check for leaks wearing a face shield and safety goggles.

b. Wear rubberized gloves.

c. Wear protective clothes.

d. Do not use your hands to detect a hydraulic fluid leak. Use a large

piece of wood, cardboard or paper and watch for discolouration.

8. A damaged or disconnected hydraulic hose under pressure may whip

around and inflict personal injury or damage the work area. Secure the

hose to a fixed or permanent structure with clamps or cable ties.

9. Change your clothing immediately if sprayed with hydraulic fluid. Store

clothing or rags contaminated with hydraulic fluid in an approved metal

safety can with a spring-closing lid and venting designed to contain a fire.

10. Do not expose the fluid to an ignition source. Hydraulic fluid has a

combustible flash point of approximately 200°F (93°C). Consult the

material Safety Datasheet (MSDS) for your hydraulic oil to determine the

actual flashpoint.

WARNING! Only qualified service personnel should repair the tool. An

improperly repaired tool may present a hazard to the user and/or others.

HYDRAULIC RAM MAINTENANCE

Monthly maintenance is recommended for the hydraulic ram. Any restrictions due

to dirt, rust, etc. can cause the either slow movement or extremely rapid jerks,

damaging the internal components. The following steps are designed to keep the

pump maintained and operational.

1. Lubricate the cylinder and the pumping mechanism with light oil.

2. Visually inspect for cracked welds, bent, loose, missing parts or hydraulic

oil leaks.

3. Inspect the hydraulic ram immediately if it was subjected to an abnormal

load or shock load.

4. Remove any hydraulic pump from service that is damaged, worn down or

operates abnormally, until repaired by an authorized service technician.

5. Check and maintain the ram oil level.

6. Always store your press with the hydraulic ram in the fully retracted

position. This will help protect critical areas from corrosion.

7. Do not use brake or transmission fluids or regular motor oil as they can

damage the seals. Always purchase and use products labeled Hydraulic Oil.

BLEEDING THE HYDRAULIC SYSTEM

Bleed excess air from the hydraulic system as follows:

1. Open the release valve by turning it counterclockwise.

2. Remove the oil filler screw and fill the pump with hydraulic fluid.

3. Wait 5 minutes for trapped air to rise to the surface.

4. Pump the handle or pedal for several full strokes to eliminate any air in

the system.

5. Check the oil filler hole and if necessary, top off with more hydraulic oil.
