SECTION III - BASIC MACHINE OPERATION
3.14 CAUTION ON USING RUBBER CRAWLER SHOES A. PROPER USAGE The rubber crawler shoe offers excellent features which a steel crawler shoe does not possess. However, if it is used in the same way as the steel crawler shoe, then its advantages can not be fully taken. Operation of the machine varies upon site and working conditions. Comparison between rubber and steel crawler shoes: Rubber shoe Steel shoe Less vibration Smooth run Low noise Harmless for paved road Easy handling Not damageable Large traction force = Excellent
= Good
= Ordinary
B. PROHIBITED WORK Do not carry out the following operations: 1. Do not operate and/nor travel in gravelmixed land, rugged and solid rock bed, ferroconcrete, iron scraps, edges of iron plates.
2. Do not operate and/nor travel in such places as river beds where there are lots of stones of different sizes. The rubber crawler shoe tends to be damaged or come off from the rollers as the result of being caught in the grooves on the rubber crawler shoes. The service life of the rubber crawler shoe will be reduced if soil is pushed by force when the rubber crawler shoe is slipping. 3. Do not let oil, fuel, solvents, etc., come in contact with rubber shoes. If it does, wipe it off with a cloth immediately. Do not travel on a puddle of oil, etc. on the road surface.

* Although the rubber crawler shoe displays many advantages because of its material properties, it has disadvantages in terms of strength. It is therefore necessary to get fully familiar with the characteristics of the rubber crawler shoe and observe what are prohibited and cautioned against, in order to extend the service life of the rubber crawler shoe and have it fulfill its advantages to a maximum possible extent. Read throughly the section III “CAUTIONS ON USING RUBBER SHOES” before use. * GUARANTEE OF RUBBER CRAWLER SHOE Guarantee does not cover such damages done to the rubber crawler shoe that result from improper working and/or operation as: execution of site work in such places where there are steel plates, U-drains, block corners, sharp slashed gravel and stones, ferroconcrete debris, metal scraps and others which may tear off the rubber crawler shoe, and neglect to observe prohibited operations.
