the hoses if necessary.
CHECK AIR VALVES & CYLINDERS FOR LEAKS
All air valves and cylinders should be checked
periodically for leaks. To do so, actuate the valve or
cylinder and coat the device with a soap solution.
Leakage which causes a bubble one inch or larger to
form in one second is considered excessive, and the
device should be scheduled for repair or replacement.
CLEAN STEERING/OUTRIGGER FILTER
The power steering/outrigger filter is located on the left
side of the engine compartment, ahead of the radiator.
Access to the filter is gained by reaching up from below
the front of the machine

before resistance is felt, and is best checked by hand.
