3.3 Operation
11. Check for damage to seat belt and mounting clamps.
Check that there are no loose bolts on the equipment mount-
ing the seat belt to the machine, and tighten if necessary.
If the belt is damaged or fluff is starting to form, or if there is
any damage or deformation of the seat belt holders, replace
the seat belt.
12. Clean cab window.
Clean the cab window to ensure good visibility when operat-
ing the machine.
When cleaning the front glass, articulate the machine and
climb on the step at the center of the front frame.
Clean the cab glass only on the side to which the machine is
articulated. Using the step in the center of the front frame to
move to the opposite side from the side which is articulated
is extremely dangerous. Do not do this.
When cleaning the opposite side, first articulate the machine
in the opposite direction, then carry out the cleaning.
When articulating the machine, articulate it to an angle of at
least 38° from the line to the front. If the angle of articulation
is small, it is a long distance to the step in the center of the
front frame, and this creates a dangerous situation.
13. Check and cleaning of the rear view mirrors.
Check the rear view mirrors for breakage, and replace any
broken one. Clean the surface of each mirror and adjust the
angle so that the rear view can be seen clearly from the
operator's platform.
