  • Mode Selection Switch (Engine speed control switch) match engine power with hydraulic output integrate power mode and work mode for easy controlMode Working Condition OutputP - Power Max Maximum Speed 100%H -Heavy duty Maximum productivity 95%G -General purpose Economical operation 90%F -Fine control Maximum lifting power 70%I -Idle setting Maximum warm-up 60%
  • Gradeability (Ө)• possible angle for machine to climb up• Ө = 35 degreeMax. travel speed : 3-5 km/hMax. slew speed : 8.8 rpm
  • Service refill capacities Fuel tank ……………………………………….685 L Hydraulic system total……………………520 L Hydraulic tank……………………………….270 L Engine oil……………………………………….42L

  • Digging forceTear-out force(arm digging force)Break-out force(bucket digging force)
  • Bucket breakout force loss when using an quick fit or long tip radiusbucket.The shorter tip radius bucket provide more digging force than thelonger.Tipradius(A)(B) (B)% loss in bucket breakout force = ( B – A ) / B * 100Bucket breakout force loss due to increasing the width of a bucket.The narrower bucket provide more digging force than the wider.% loss in bucket breakout force = ( B – C ) / B * 100(B) (C)Digging force effect1. By bucket tip radius2. By bucket width
