2.2 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 con-
scious 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 mate-
rials out of the 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 in order 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 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 containers 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 eyebolt or
similar bracket lessens, as the angle between the sup-
porting structure and the component becomes less
than 90 degrees.
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.
Component Disassembly and Reassembly
When disassembling or reassembling a component, complete
the procedural steps in sequence. Do not partially disassemble
or assemble one part, then start on another. Always recheck
your work to assure that nothing has been overlooked. Do not
make any adjustments, other than those recommended, with-
out obtaining proper approval.
