EXPLANATION OF COMPONENTS
SLIDE DOOR
k
Be sure to check that the sliding door is locked in po-
sition both when it is open and when it is closed.
Always place the machine on a level ground when
opening or closing the door.
Avoid opening or closing the door on a slope, since
there is a danger that the operating effort may sudden-
ly change.
When opening or closing the door, always use door
handle (1) and knob (2).
Be careful not to get your hands caught between the
front pillar or center pillar.
When there is anyone inside the cab, always call out a
warning before opening or closing the door.
Door lock
When closing the door, pull door handle (1) back to unlatch lock (3), then pull the door to the front.
EMERGENCY ESCAPE HAMMER
If it is necessary to break the window glass with the hammer, be extremely careful not to get injured
with scattered pieces of broken glass.
To prevent injury, remove the broken pieces of glass remaining in the frame before escaping
through the window. Be careful also not to slip on the broken pieces of glass.
If it should become impossible to open the cab door for any
reason, and it is necessary to make an emergency escape
from the operator's compartment, use hammer to escape.
To escape from the operator's cab, use hammer to break the
glass and escape through the window.
CAP AND COVER WITH LOCK
Use the starting switch key to open and close the locks on the caps and covers.
