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
working on or around 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. Always provide adequate support when lift-
ing a portion of the equipment.
Cleanliness
1.
The most important single item in preserving the long
service life of a machine is to keep dirt and foreign mate-
rials out of vital components. Precautions 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 to function properly.
2.
At any time when air, fuel, or oil lines are disconnected,
clear adjacent areas as well as the openings and fittings
themselves. As soon as a line or component is discon-
nected, cap or cover all openings to prevent entry of for-
eign matter.
3.
Clean and inspect all parts during servicing or mainte-
nance, and ensure all passages and openings are unob-
structed. Cover all parts to keep them clean. Be sure all
parts are clean before they are installed. New parts
should remain in their containers until needed.
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.
If a component must be removed on an angle, keep in
mind the capacity of an eyebolt or similar bracket less-
ens, as the angle between the supporting structure and
the component becomes less than 90 degrees.
3.
If a part resists removal, check if all nuts, bolts, cables,
brackets, wiring, etc., have been removed and that no
adjacent parts are interfering.
