hitachi — PRECAUTIONS FOR CRUSHER OPERATION

OPERATING THE MACHINE PRECAUTIONS FOR CRUSHER OPERATION Prevent machine tipping over and damage to the front attach- ment. Observe the following precautions for crusher opera- tion. WARNING: Machine stability is reduced as crusher is much heavier than bucket. When operating with a crusher, the machine is more apt to tip over. Also, falling or flying objects may hit the cab or other part of the machine. Observe the fol- lowing precautions and take any other precautions necessary to prevent accidents and machine damage from occurring. • Do not allow the machine’s weight to be supported by the crusher or bucket cylinder with the bucket cylinder fully extended or retracted.

Doing so may damage the front attachment. In particular, avoid doing so with the bucket cylinder fully extended, as the front attachment will be easily damaged. Take care to prevent this from happening when disman- tling foundation structures using the crusher. • Using the front attachment, don’t raise the base machine off the ground with the arm cylinder fully extended. Fail- ure to do so may result in damage to the arm cylinder. • When a heavyweight attachment such as a crusher is installed, avoid quickly starting or stopping the front at- tachment. Failure to do so may result in damage to the front attachment. • Do not attempt to perform crushing on either side of the machine.

Always perform crushing operations to the fore or rear, parallel with the tracks. Otherwise, tipping over may occur. WRONG M107-05-046 WRONG • Operate the hydraulic excavator carefully to avoid hitting the boom, and cab. M107-05-047 WRONG M1G6-05-009 5-26
