TROUBLES AND ACTIONS 3.7.4 SEVERE JOB CONDITION When digging in water, if the water gets on to the work equipment mounting pins, add grease to bucket links (A), (B), (C), (D) and (E) for each operation. When carrying out heavy duty digging and deep digging op- erations, add grease to bucket links (A), (B), (C), (D) and (E) (total: 5 points) before each operation. After greasing, operate the bucket several times, then add grease again. 3.7.5 DISCHARGED BATTERY WARNING When checking or handling the battery, stop the engine and turn the starting switch key to the OFF position. The battery generates hydrogen gas, so there is a haz- ard of explosion.
Do not bring lighted cigarettes near the battery, or do anything that will cause sparks. Battery electrolyte is dilute sulphuric acid, and it will at- tack your clothes and skin. If it gets on your clothes or on your skin, immediately wash it off with a large amount of water. If it gets in your eyes, wash it out with fresh water and consult a doctor. When handling batteries, always wear protective gog- gles and rubber gloves. When removing the battery, first disconnect the cable from the ground (normally the negative (-) terminal). When installing, install the positive (+) terminal first.
If a tool touches the positive terminal and the chassis, there is danger that it will cause a spark, so be extreme- ly careful. If the terminals are loose, there is danger that the defec- tive contact may generate sparks that will cause an ex- plosion. When removing or installing the terminals, check which is the positive (+) terminal and which is the negative (-) terminal. 147
