• Before getting on and off the machine, check
the handrails and steps for any damage or
looseness, and make sure they are free of any
oil and dirt. Always keep the handrails and
steps free of oil and dirt to prevent slipping.
Repair any damage and retighten any loose
bolts.
• Do not grab control levers or safety lock levers
when getting on and off the machine.
• Never step on the engine bonnet or cover, as
they do not have a non-slip surface.
• Do not get on or off the machine while holding
tools or other items in your hands.
• Do not jump on or off the machine, and do not
get on or off the machine while it is moving.
• Even if the machine unexpectedly begins to
move with an operator, never attempt to jump
on the machine in order to stop it.
PRECAUTIONS WHEN STANDING UP OR
LEAVING THE OPERATOR'S SEAT
• Before standing up from the operator's seat to
open or close the front or roof windows, detach
or attach the lower window, or adjust the
operator's seat, be sure to retract the crane and
set the lock lever (1) to the "LOCK" position (L)
and turn off the engine.
Inadvertently touching control levers may cause
the machine to suddenly move, resulting in
serious personal injury.
• When leaving the machine, be sure to retract
the crane, set the lock lever (1) to the "LOCK"
position (L), and turn off the engine. Also lock all
of the locks, remove the keys, and store them in
a designated place.
OPERATOR'S CAB EMERGENCY EXIT
• If the cab door cannot be opened in an
emergency, use the hammer provided to break
the window and escape through the opening.
• When escaping, remove any pieces of glass
from the window frame to avoid injury. Also take
care not to slip on pieces of the broken glass.
