NOTICE In some instances it may be possible to hit the cab with the bucket or attachment. To prevent
damage care should be taken when operating with the bucket/attachment close to the cab.
The right hand joystick controls the movements of the dipper and the bucket. When released, the joystick
returns to the neutral position.
The dipper will move within its limits for as long as you hold the joystick forward or backwards. It will stop
automatically when you release the joystick.
To move the dipper outwards, move the joystick forwards (position 2).
To move the dipper inwards, move the joystick backwards (position 1).
The bucket will move within its limits for as long as you hold the joystick to one side. It will stop automatically
when you release the joystick.
To fill the bucket, move the joystick to the left (position 3).
To empty the bucket, move the joystick to the right (position 4).
Press the power boost button to enable improved breakout for 3s.
When a Quickhitch system is installed (position bucket on floor), press the Quickhitch button to release the
