Translation of the original instructions RUBBER CRAWLER TRACKS PRECAUTIONS FOR USE 1 TRACK TENSION Fig 6 1 When the machine is lifted off the ground the rubber tracks must sag by 10 15 mm as shown in the diagram Fig 10 Rubber crawler tension 2 When the track becomes slack it must be adjusted to prevent the machine from shedding an excessively loose track 2 PRECAUTIONS WHEN DRIVING 1 Avoid jerky operations when the crawler truck is in motion 2 Keep the rubber crawler track away from sharp edges of concrete etc 3 Cracks on the outside surface of the rubber track in contact with the ground are very often due to contact with gravel sharp stones and sharp materials such as sheet metal nails and glass 3 AVOID SUDDEN CHANGES IN DIRECTION Sharp turns on concrete surfaces or excessive accelerations which generate high friction coefficients must be avoided since they might cause cuts in the rubber 4 AVOID CONTAMINATION WITH OIL Fuels and hydraulic fluids must never come into contact with the rubber crawler track If this should occur clean imemdiately 5 REPLACING THE SPROCKET If abrasions and wear are noted on the sprocket it must be replaced as soon as possible since in these conditions it might cause abrasion or reveal the metal core 6 OPERATING TEMPERATURE The ideal operating temperature for the rubber crawler track is between 25 and 55 C because of the fundamental properties of the rubber 12
