SERVICE AND GUIDELINES
General
The following information is provided to assist you in the
use and application of servicing and maintenance proce-
dures 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 for-
eign materials out of the vital components. Precau-
tions 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 openings
and fittings themselves. As soon as a line or compo-
nent is disconnected, cap or cover all openings to
prevent entry of foreign matter.
3.
Clean and inspect all parts during servicing or main-
tenance, 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 contain-
ers 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 component
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 interfering.
