General maintenance practices are given in this section. This information will not be repeated in any other part of this manual.
SAFETY
Safety is always the most important consideration when working on this vehicle. Understand completely the job to be done and use common sense.
Don't just do the job. Do it safely. Shipping link must be installed before any maintenance.
REMOVING PARTS
Always respect the weight of a part. Use a hoist whenever necessary. Don't lift heavy parts by hand. A hoist and adjustable lifting beam or sling are
needed to remove most parts. The length of chain or cable from the hoist to the part being lifted should be parallel and should be positioned directly
over the center of the part. Never leave a part hoisted in mid-air.
Always use blocking to support the part that has been hoisted. If you cannot remove a part, check to see that all capscrews and attached hardware
have been removed. Check to see if any parts are in the way of the part being hoisted.
CLEANING
Keep all dirt out of parts. The vehicle will perform better. Seals, filters, and covers are used in this vehicle to keep it clean. They must be kept in good
shape to help the vehicle run well.
Clean and look at all parts when removing parts. Make sure all holes and passages are clean and open. After cleaning parts, be sure to cover them with
a clean cloth, paper, or other clean material. Make sure the part is clean when it is installed.
Always clean around air lines, hydraulic lines, or covers before removing them. Plug, tape, or put caps on holes and openings to keep dirt out.
DISASSEMBLY AND ASSEMBLY
Always put together or take apart one part at a time. Do not work on two parts at the same time. Be sure to make all adjustments. Always check your
work when you are finished. Make sure everything is done.
Check the adjustments for the last time by operating the vehicle. If all adjustments are correct, the vehicle is ready to go back to work.
