Komatsu — 3.3.6.2 MACHINE CONTROLS (version with servo-assisted backhoe)

INSTRUMENTS AND CONTROLS 21 - PATTERN CHANGE CONTROL LEVER (if provided and only for the version with servo-assisted backhoe) q Before using the pattern change control lever to modify the machine’s operating pattern, lower the equipment to the ground and stop the engine. q After changing the control operating pattern, carry out the first manoeuvres slowly and very carefully, in order to understand the new controls correctly and to avoid any damage or fatal injury that may be caused by incorrect movements.

q After changing the control operating pattern and before checking the movements of the machine, make sure that the area is clear of obstacles and that no one is standing in the range of movement of the machine. The pattern change control is positioned on the rear central part of the cab floor and allows the operator to choose the control pattern he prefers. The pattern change control lever (21) has two positions: q Pos. 1: ISO PATTERN control system Lever in position B . q Pos. 2: OPTION PATTERN control system Lever in position C . The control lever (21) is held in its position by means of a safety screw (D).

When it is necessary to change the control pattern, raise the mat and loosen the safety screw (D) until releasing the lever (21) completely. Select the desired control pattern by rotating the lever (21) horizontally and secure it in its position by means of the safety screw (D). Put back the mat. IMPORTANT q All movements of the boom and the equipment are inhibited when the safety button (A) is in locking position (LED on) (see "3.3.2 pos. 12 - SERVO CONTROL LOCKING BUTTON"). q Before moving the machine the operator must make sure that the control pattern selected with the lever (21) corresponds perfectly to the control pattern indicated on the front part of the respective joysticks.

If necessary, turn the corresponding plates (E) by 180°. 113 WARNING
