3.5.2 Main Stair Frame Installation
Installation is the reverse of removal.
3.6 Electrical Components Removal and Installation
Electrical system components are conventional items requiring conventional
methods of mounting. An automotive mechanic possessing normal skills can
accomplish removal and installation of any electrical part with little effort. Use
the schematic diagram in this Chapter and the exploded views and parts
listings in Chapter 4 as a guide.
3.7 Hydraulic System
Plumbing within the hydraulic system uses standard hydraulic lines, fittings,
and hoses. Relief and check valve installations follow normal hydraulic system
layout and mounting methods, assuring uncomplicated maintenance
procedures. Major assemblies require more attention to installation methods.
During removal of major components, observe mounting and installation, type
of mounting hardware, and note order of disassembly. Also note any other
peculiarities which will assist during installation. After replacing any component
in the hydraulic system, run a complete operational check.
NOTICE!
Use only MOBIL DTE-13 or equivalent in operating temperatures of
+20°F to +120°F (-7°C to +50°C). Use Mobil Aero HFA or equivalent
(MIL-H-5606A) in operating temperatures of -25°F to +50°F (-32°C to +10°C).
Do not use hydraulic oils of different specifications. They may not be
compatible and could result in damage to the hydraulic system components.
3.7.1 Hydraulic System Safety
To minimize risk of serious injury or death, follow these
hydraulic servicing precautions:
Follow all necessary lockout/tagout procedures.
•
Hydraulic systems have residual, stored pressure. Relieve all pressure
from the hydraulic system before servicing.
•
Allow fluid to cool before working on system.
•
Hydraulic fluid escaping under pressure can have sufficient force to enter
eyes and penetrate skin. If fluid gets in eyes or skin, flush with large
quantities of water and seek medical attention.
•
Wear eye protection when servicing hydraulic components or systems.
•
Keep all hoses and connections in good serviceable condition. Check
before start-up and periodically during operation.
•
Do not investigate for leaks with hands. Use a large piece of cardboard.
