INSTRUMENTS AND CONTROLS To use the levers correctly, proceed as follows: 1 - With the machine at rest and the engine off, seat correctly and rotate the seat by 180° with respect to the driving position. 2 - Adjust both joysticks until they reach the desired operating position (see "3.3.6.3 pos. 3 ARM SUPPORT ADJUSTING KNOB (only for the version with servo-assisted backhoe)"). The position of the joysticks during work can be adjusted by means of the respective knobs positioned on the cab floor (see "3.3.6.3 pos. 4 JOYSTICK STROKE ADJUSTING KNOB (only for the version with servo-assisted backhoe)").
3 - Adjust the height of the arm supports (B) by means of the adjusting knobs, until finding the position that is most suitable to your physical structure (see "3.3.6.3 pos. 3 ARM SUPPORT ADJUSTING KNOB (only for the version with servo-assisted backhoe)"). 4 - Once the correct operating position of both joysticks has been found, fasten the safety belt and start the machine (see "3.6.2 STARTING THE ENGINE"). Press the button (A) (LED off) to release the servo controls and start work. 5 - At the end of work lower the equipment to the ground and lock the controls again with button (A) (LED on).
6 - Before rotating the seat to the driving position, shift the joysticks in vertical position, paying attention to the safety distance from the rear window. If the end of stroke of the joysticks needs adjusting, use the screws positioned on the front part of the same (see "3.3.6.3 pos. 4 JOYSTICK STROKE ADJUSTING KNOB (only for the version with servo-assisted backhoe)"). The control lever (19) is positioned to the operator’s left and controls the arm and the swing, while the control lever (20) positioned to the operator’s right controls the boom and the bucket. On request, the machine can be equipped with two different control patterns at the same time, more precisely:
1 - ISO PATTERN CONTROLS (Standard) 2 - KOMATSU PATTERN CONTROLS (Optional) The choice of the control pattern is up to the operator; for the selection of the pattern desired, see paragraph " 21 - PATTERN CHANGE CONTROL LEVER (if provided and only for the version with servo-assisted backhoe)". The patterns illustrated below show the basic manoeuvres and the combined manoeuvres that can be carried out with the two systems. 109
