system. The reversing fan switch is located on the left
console.
IMPORTANT: Prevent machine damage from
overheating. Do not manually reverse fan
immediately after last completion. Wait 1
minute before reactivating.
NOTE: Reversing fan is more effective at higher
engine speeds.
The reversing fan switch has three positions:
•
AUTO: Every 60 minutes, the radiator cooling fan will
automatically reverse direction for 30 seconds without
intervention from the operator when engine rpm is above
auto-idle speed. The default time setting is 60 minutes.
To adjust time setting, see an authorized Hitachi dealer.
•
OFF: Fan resumes normal operation.
•
MANUAL: Press and hold right side of switch to reverse
fan. Fan will stop reversing when switch is released or
