SERVICE AND GUIDELINES

General

The following information is provided to assist you in
the use and application of servicing and maintenance
procedures contained in this book.

Safety and Workmanship

Your safety, and that of others, is the first consideration
when engaging in the maintenance of equipment.
Always be conscious of weight. Never attempt to move
heavy parts without the aid of a mechanical device. Do
not allow heavy objects to rest in an unstable position.
When raising a portion of the equipment, ensure that
adequate support is provided.

Cleanliness

1. The most important single item in preserving the
long service life of a machine is to keep dirt and
foreign materials out of the vital components. Pre-
cautions have been taken to safeguard against
this. Shields, covers, seals, and filters are provided
to keep air, fuel, and oil supplies clean; however,
these items must be maintained on a scheduled
basis in order to function properly.
2. At any time when air, fuel, or oil lines are discon-
nected, clear adjacent areas as well as the open-
ings and fittings themselves. As soon as a line or

component is disconnected, cap or cover all open-
ings to prevent entry of foreign matter.
3. Clean and inspect all parts during servicing or
maintenance, and assure that all passages and
openings are unobstructed. Cover all parts to keep
them clean. Be sure all parts are clean before they
are installed. New parts should remain in their con-
tainers until they are ready to be used.

Components Removal and Installation

1. Use adjustable lifting devices, whenever possible,
if mechanical assistance is required. All slings
(chains, cables, etc.) should be parallel to each
other and as near perpendicular as possible to top
of part being lifted.
2. Should it be necessary to remove a component on
an angle, keep in mind that the capacity of an eye-
bolt or similar bracket lessens, as the angle
between the supporting structure and the compo-
nent becomes less than 90°.
3. If a part resists removal, check to see whether all
nuts, bolts, cables, brackets, wiring, etc., have been
removed and that no adjacent parts are interfer-
ing.
