When using the door-open lock, be sure to apply the lock
securely.

HANDLING CAB WIPER 3
PREVENTING DAMAGE TO WIPER ARM BRACKET 3
NOTICE
When angling the wiper arm to the front, check that the
wiper blade is hanging free.
When angling the wiper arm to the front, such as when wiping
the glass clean, if the wiper arm is angled with the wiper blade
locked to the arm (the bottom of the blade is caught on the
arm), abnormal force is brought to bear on the mounting
bracket and the bracket may break.
REPLACING CAB WIPER 3
WARNING
Do not attempt to replace the cab wiper, standing on the front frame. It is very dangerous to climb on the
front frame.
When replacing the cab wiper, articulate the machine 40° to the
right, place stand (1) in position, then stand on it and replace
the wiper. Be careful not to fall off the stand.
