Floor Tilt Down Procedure
d
WARNING:
 Be sure to tilt down the cab after checking or
servicing. At this time, be sure to store the fall
prevention bar first, and then slowly tilt down the
cab. If the fall prevention bar is not stored before
tilting down the cab, the cab tilting device may be
broken.
 Perform cab tilt down operation manually. Do not
use compressed air or electrical tools. If adjusting
screw (1) is quickly turned by using compressed air
or electrical tool, the floor will rapidly lowered and it
may severely vibrate, potentially creating hazardous
conditions.
1. Before tilting the cab floor down, check if any tools
or workshop towels are not left behind on the base
machine or in the operator's cab, and fall prevention
bar (2) has been stowed in position. When stowing fall
prevention bar (2), raise fall prevention bar (2) in the
arrowed direction, and then slide it backward.
IMPORTANT: Do not attempt to tilt down the cab after
the stoppers (3) contact each other. Failure to do so
may result in breakage of the cab tilting device.
2. Slowly turn adjuster (1) clockwise until the body contacts
with stopper (3).
Wrench size: 17 mm
3. Ensure that no load is applied to the cab tilting device.
Draw the cab tilting device forward.
