Pressure Limiting Valve

If the hydraulic pressure is too low, it can be
due to dirt trapped in the pressure limiting
valve.
IMPORTANT INFORMATION
Incorrect hydraulic pressure is almost
never due to an incorrectly adjusted
pressure limiting valve. Check the
hydraulic system thoroughly for faults
before changing the valve setting.
IMPORTANT INFORMATION
An excess flow valve that is set too high
will damage the power steering.

Hose Bundle

The hoses under the machine are collected
into a hose bundle. This is held together by
means of a plastic hose protection, which is
wound around the hoses.
When manufactured the hoses are colour
coded, but this may wear off or be damaged.
It is then possible to identify the hoses by the
punched part numbers.
