When working on engine and operating the engine throttle arm by
hand, disconnect throttle linkage from the control slave. If linkage
is not disconnected the pilot check valve will not allow a throttle
retardation unless a sender arm is actuated to decrease the throttle.
Prior to starting engines, both throttles and clutches should be synchronized.
This is done by moving the sender’s control arm in a complete cycle fore
and aft, stop to stop. This needs to be done at only one station.

The reservoir pressure will vary between 70-90 psi due to temperature
changes. There is no reason to become alarmed unless the pressure
drops below 70 psi, then the system should be repressurized to 80+
psi. If the pressure loss is over a relatively short period check for air
leakage. Should the pressure loss from full pressure to minimal
operation pressure be over an extended time period just repressurize
the system. This extended pressure loss is normal and may be
compared to the same type pressure loss one experiences with a
good set of automotive tires after an extended time.
