WARNING
• Adjust the seat before starting operation or

so that you can sufficiently operate the
control levers, switches, and accelerator
pedal.
• Be sure to stop the engine before adjusting

desired position, and release your hand from the

[Seat reclining adjustment]
Pull the lever (2) upward, adjust the seat back to a
position allowing easy operation, and release your
hand from the lever (2).

The degree of seat recline is larger when the

Return the seat back to the original position
when moving the seat backward.

Push your back into the seat back when
adjusting. Otherwise, the seat back may
suddenly flip back.

[10] Irregular winding check mirror
adjustment
CAUTION
Be sure to adjust the mirror before operation.
If the mirror is poorly adjusted, irregular
winding caused by the winch drum cannot be
checked. This will not only damage the wire
rope but also shake the hoisted load at the
time of lowering, possibly leading to
instability and serious personal injury.
Adjust the mirror (1) mounting so that the operator
has a clear view of the winch drum.
• If the mirror is stiff when adjusting, loosen the
mirror bolts to adjust.
