To do so: Ensure that all threads are clean with no damage [1] Press the male coupler into the female

coupler, [2] then turn the threaded-collar clockwise (by hand) until the threads are fully engaged.

IMPORTANT:

Make sure that all coupler threads are fully engaged.

Only use hoses with a 4:1 safety rating on burst pressure.

6.4 Bleeding Trapped Air from the Hydraulic System

The bleeding of trapped air from a hydraulic system must only be performed by qualified

personnel who have been trained and are competent to do so.

The method of air removal will depend on the hydraulic system under test. Safe, effective methods of air

removal, must be established before starting any operation. Pressure testing with air trapped in the hydraulic

system can lead to an increased risk to the equipment and the operator.

NOTE: To reduce the likelihood of introducing air into the hydraulic system, make sure that all hoses are

pre-filled with fluid before connecting them to the hydraulic system.

Cylinder and hoses are not always completely filled with oil when new. For safe and efficient operation,

trapped air must be removed from the system. The following procedure must be carried out with the

cylinder/s connected to the pump, but not operating under load.

To remove air from the system, proceed as detailed below:



Figure 5.2

Make sure the pumps oil filler breather cap is fitted. (if applicable)

With all hydraulic connections made, position the cylinder/s below the level of the

hydraulic pump, as illustrated in figure 5.2.

Using the pump, fully advance and retract the cylinder/tool piston several times

until the operation is smooth. (Refer to the pumps operating

manual for details of pump operation).
