Good working practices

Special service tools
Use the recommended special service tools
to protect parts from damage. Use the right
tool in the right manner–do not improvise.

provided throughout the manual. When tight-
ening nuts, bolts, and screws, tighten the
large sizes first, and tighten fasteners starting
in the center and moving outward.
Non-reusable parts
Always use new gaskets, seals, O-rings, cot-
ter pins, circlips, etc., when installing or
assembling parts.
