MAINTENANCE AND
SERVICING PRECAUTIONS
GENERAL
This section assists you in the use and application of
the maintenance and servicing procedures contained in
this manual.
SAFETY AND WORKMANSHIP
Your safety, and that of others, is the first consideration
when engaging in the maintanance of equipment.
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
service life of a machine is to keep dirt and foreign
materials 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 to
function properly.
2. When air, fuel or oil lines are disconnected, clean
the adjacent areas as well as the openings and
fittings. As soon as a component or line is
disconnected, cap or cover all openings to prevent
entry of foreign matter.
3. Clean and inspect all parts during servicing and
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
containers until they are ready to be used.
COMPONENT 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
