CHECK POINTS WHEN USING BREAKER
• Is the selector valve (1) in position (b) for breaker (1 way)?
If it is not in position (b) for breaker (1 way), turn it to the
position.
• Is the engine output set at 80 %?
• Do you replace the hydraulic oil and its filter element at intervals shorter than the standard?
The deterioration of the hydraulic oil when using the breaker is much faster than in the normal operations,
so check the maintenance time by referring to “MAINTENANCE INTERVAL FOR HYDRAULIC BREAKER”.
• When handling the breaker, follow the instruction manual from the manufacturer and use the breaker cor-
rectly.
METHOD FOR OPERATING MACHINE WHEN WORKING MODE IS NOT IN
BREAKER MODE
If the working mode display does not indicate the breaker mode, set it to breaker mode according to the follow-
