BLEEDING AIR FROM THE HYDRAULIC BOTTLE JACK

Air may accumulate within an hydraulic bottle jack during shipment or after prolonged use; this air can cause the hydraulic

bottle jack to respond "weak". Please use the steps below to bleed the air from the hydraulic bottle jack.

a - Use the notched end of the provided handle to engage and open the release valve counterclockwise for no more than

1/2 full turn.

b - Locate and remove the oil filter plug.

c - Insert the handle into the handle sleeve, fully extend and retract ram 6 to 8 times. This will help release and pressurized

air which may be trapped within the reservoir.

Note : Ensure the oil level is just below the oil filter plug hole. Reinstall the oil filter plug and close the release valve.

3. MAINTENANCE (§ 7.1.3 de l'EN 1494+A1)

Important: Both the maintenance and repair of the hydraulic bottle jack may only be performed by qualified persons, who have sufficient knowledge of the

hydraulic systems used in these devices as a result of their training and experience.

3.1

Keep the hydraulic bottle jack clean and lubricate all moving parts at regular intervals, which must be clean and protected from aggressive conditions at

all times.

3.2

Only original spare parts should be used.

3.3

Prior to each use, check for bent, broken, cracked or loose parts and solve the problem, if appropriate. If it is suspected that the hydraulic bottle jack has

been subjected to abnormal loads or has suffered any knocks, withdraw it from service until the problem has been rectified.

3.4

If the oil level needs to be checked or refilled, with the piston fully retracted, remove the filler plug and drain its contents into a container. With the

hydraulic bottle jack in a horizontal position, proceed to introduce the necessary volume as indicated for each model in these instructions.

The parts table alongside shows the volume of oil required, and the levels with respect to the oil filler hole for each model.

Make sure that no dirt enters with the new oil.

Following a period of prolonged intensive use, it is recommendable to change the oil in order to extend the useful life of the hydraulic bottle jack.

Important: An excess of oil to the volume required may render the hydraulic bottle jack inoperative.

3.5

Only use hydraulic oil

ISO VG

Extremely Important: Never use brake fluid.

3.6

When the hydraulic bottle jack is not in use, the screw, main piston and the pump piston should be retracted to avoid corrosion.

Apply an anti-corrosion product to the pistons, if appropriate.

Remove the handle from its position.

3.7

At the end of the useful life of the hydraulic bottle jack, drain off the oil and hand it over to an authorised agent and dispose of the jack in accordance

with local regulations.

3.8

Both the repair kit, which exclusively contains the o-rings and seals of the hydraulic bottle jack, and the spare part sets must be ordered using the

reference assigned in the table.

4. PREVENTIVE MAINTENANCE

Important: Dirt is the greatest single cause of failure in hydraulic units. Keep the hydraulic bottle jack clean and well lubricated to prevent foreign

matter from entering the system. If the hydraulic bottle jack has been exposed to rain, snow, sand, or grit, it must be cleaned before it is used. The

use of alcohol, hydraulic brake fluid, detergent motor oil, or transmission oil could damage the seals and result in hydraulic bottle jack failure. Use

only approved hydraulic fluid (type ISO VG 13).

4.1

When the hydraulic bottle jack is not is use, keep the piston and pump rods fully retracted. Store the hydraulic bottle jack on its base (in an upright

position) and in a well protected area where it will not be exposed to corrosive vapors, abrasive dust, or any other harmful elements.

4.2

Maintain the oil level at the bottom of the filler plug hole. If it's necessary to add oil, remove the filler plug, and fill the reservoir.

4.3

Visually inspect the hydraulic bottle jack before each use. Take corrective action if any of the following problems are found:

a. Cracked or damaged housing

b. Excessive wear, bending, or other damage

c. Leaking hydraulic fluid

d. Scored or damaged piston rod
