1 - REVERSING GEAR LEVER
WARNING
q
When it is necessary to park or leave the machine unattended, even if temporarily, shift the lever to posi-
tion (N) and always apply the parking brake.
q
The machine is equipped with an acoustic alarm that is activated if the operator, with the engine run-
ning, shifts the reversing gear lever (1) to position F or R with the seat rotated in any position different
from the correct driving position.
This is a danger signal, since it is absolutely forbidden to move the machine while working with the
backhoe equipment or in any case with the seat rotated by 180° with respect to the regular driving posi-
tion.
Remember that the operator is allowed to move the machine only when seated in the correct driving po-
sition, with locked seat and fastened safety belt.
q
Non-compliance with these rules may cause serious accidents.
IMPORTANT
q
Operate the lever only when the engine is running at low speed.
q
The engine can be started only with the lever in neutral position (N).
q
If the operator deems it necessary, the machine may also be equipped with an acoustic alarm for move-
ments in reverse.
This device can be installed on a special area in the rear part of the frame (see "2.4.4 CHECKS FOR
TRAVELLING IN REVERSE"); before travelling in reverse, make sure that the acoustic alarm functions
perfectly.
To check the functionality of this acoustic alarm, proceed as follows:
- start the machine (see "3.6.2 STARTING THE ENGINE");
- press the brake pedals;
- shift the reversing gear lever (1) to the reverse position R.
If the alarm doesn’t work, have the machine checked by your Komatsu Dealer.
By lifting this lever and rotating it on the vertical axis, it is pos-
sible to select:
F - the forward travel, if the lever is shifted FORWARD
R - the reverse, if the lever is shifted BACKWARD
