2.2 SERVICE AND GUIDELINES
General
Following information is provided to assist you in using servic-
ing and maintenance procedures in this manual.
Safety and Workmanship
Your safety, and that of others, is the first consideration in
maintenance of equipment. Always be conscious of weight.
Never attempt to move heavy parts without aid of a mechani-
cal device. Do not allow heavy objects to rest in an unstable
position. Ensure adequate support is provided when raising 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 contamina-
tion out of vital components. Shields, covers, seals, and
filters are provided to keep air, fuel, and oil supplies
clean; however, these items must be maintained on a
schedule to function properly.
2. Any time air, fuel, or oil lines are disconnected, clean
adjacent areas as well as the openings and fittings them-
selves. As soon as a line or component is disconnected,
cap or cover all openings to prevent contamination.
3. Clean and inspect all parts during servicing or mainte-
nance. Ensure all passages and openings are unob-
structed. Cover all parts to keep them clean. Make sure
all parts are clean before they are installed. New parts
should remain in their containers until 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 the capacity of an eyebolt or similar
bracket lessens, as the angle between the supporting
structure and component becomes less than 90
degrees.
3. If a part resists removal, check to see if all nuts, bolts,
cables, brackets, wiring, etc., have been removed and no
adjacent parts are interfering.
