OPERATION
METHOD FOR ADJUSTING MIRRORS
Be sure to adjust the mirrors before starting work. If they are not adjusted properly, you cannot secure
the visibility and may be injured or may lead to a serious personal injury or death.
NOTICE
• Tighten the mirror mounting bolts securely to prevent the mirrors from coming off due to loosening
of the bolt.
Tightening torque of mirrors (A) and (B): 2.0 to 2.5 Nm {0.2 to 0.25 kgm}
• If the torque cannot be controlled, ask your Komatsu distributor for adjustment.
Mirrors (A), (B)
Loosen bolt (1) of the mirror, then adjust the mirror to a position
which gives the best view from the operator's seat of the blind
spot at the right and left sides of the rear of the machine.
Adjust the mirror angle so that you can see a person who is
standing at the right or left rear end position of the machine (or
an object having the diameter of approximately 30 cm and the
height of approximately 1 m).
Install the mirror to a position where you can easily see the
hatched area in the figure.
The reference values of the visibility range are as follows.
Visibility range (left): 2500 mm
Visibility range (right): 2500 mm
Mirror (A) Hatched area (a) must be in view.
Mirror (B) Hatched area (b) must be in view.
