ATTACHMENT OPERATIONS 6.3 ATTACHMENT OPERATIONS If you leave your foot resting on the pedal during operations and you depress the pedal by mistake, there is danger that the attachment will suddenly move and cause serious personal injury. Always lock the pedal with the lock plate except when operating the pedal. The operation of the attachment is as follows. WHEN USING BREAKER Depress the bottom of the pedal to operate the breaker. NOTE If it is necessary to adjust the oil flow, please ask your Ko- matsu Dealer to carry out the adjustment. Precautions when Using Check that selector valve (1) is at the 1 WAY (breaker) posi- tion (a).
When using the breaker, pull the fuel control lever back fully, then return it slightly and keep it in this position for opera- tions. (The position for 80% of engine output). If the breaker is operated with the engine at full throttle, it will lead to failure. When using the breaker, the hydraulic oil deteriorates more and replace the element at a shorter interval. (For details, see "4.8.2 MAINTENANCE INTERVAL FOR HYDRAULIC BREAKER".)
