) for general safety
instructions to be considered in performing
maintenance on aircraft.

) and (refer to para
1-1
)
before performing maintenance on hydraulic power
system.
3.After replacement of any component in the hydraulic
system, restore the fluid level in the reservoirs and
carry out a complete cycle of manoeuvres of the
related system before the next flight
4.If hydraulic contamination is detected, check and
eventually replace the filter elements.
5.Hydraulic fluid is acid. Prevent contact with skin.
Tighten tops must be fixed on pipes after removal.
6.In many cases, corrosion results from fingerprints
caused by careless handling. Avoid handling the units
when not necessary and keep all disassembled parts
submerged in preservative oil, Specification (LCM NO.
00083).
7.Use the test stand to operate both systems
separately. This will localise the failure in the
component of one or the other system. Since the two
hydraulic power systems are independent ofone
another, troubleshooting procedure is the same for
both. Refer to the related table for this procedure.
