Introduction

Fluid Under Pressure
Fine jets of fluid at high pressure can penetrate the
skin. Keep face and hands well clear of fluid under
pressure and wear protective glasses and gloves.
Hold a piece of cardboard close to suspected leaks
and then inspect the cardboard for signs of fluid. If
fluid penetrates your skin, get medical help
immediately.

Hydraulic Pressure
Hydraulic fluid at system pressure can injure you.
Before connecting or removing any hydraulic hose,
residual hydraulic pressure trapped in the service
hose line must be vented. Make sure the hose service
line has been vented before connecting or removing
hoses. Make sure the engine cannot be started while
the hoses are open.

Some attachments are hydraulically powered. The
following procedures show how to connect and disconnect
the hydraulic hoses safely.
Connecting the Hydraulic Hoses
1 Make the machine safe. Refer to Routine
Maintenance, Prepare the Machine for
Maintenance.
2 Vent the hydraulic system. Refer to Routine
Maintenance, Releasing the Hydraulic Pressure.
3 If necessary, remove the blanking caps.
4 Check the hoses and adaptors for damage. Refer to
Routine Maintenance, Checking for Damage.
5 Connect the hoses.
If the hoses have quick releases couplings, refer to
Quick Release Couplings.
a Make sure that the hose is not twisted. Pressure
applied to a twisted hose can cause the hose to
fail or the connections to loosen.

Fig 130.
b Make sure that the hose does not touch hot parts.
High ambient temperatures can cause the hose to
fail.
c Make sure that the hose does not touch parts
which can rub or cause abrasion.
d Use the hose clamps (where possible) to support
long hose runs and keep the hoses away from
moving parts, etc.
