COMAC OPTIMA 85B - Braking and Safety Systems; Service Brake Operation and Warnings; End of Work Procedures; Shutdown and Routine Maintenance

SERVICE BRAKE
The machine is equipped with an electronic braking system (positioned in the front traction hub) and a mechanical drum brake
system (positioned on the rear wheels).
To brake, in normal conditions, just remove your foot from the accelerator pedal. In case of malfunction of the electronic
braking system or if necessary, operate the pedal (18) located on the front left of the machine (Fig. 20).
ATTENTION: If when working, the symbol shown in (Fig. 21) appears in the control display, this means that the service
brake is active for more than ve seconds. With the machine fully stopped, check that the service brake pedal has
returned to its rest position.
ATTENTION: If when working, the symbol shown in (Fig. 21) is ashing in the control display, this means that the brake
uid level is low.
CAUTION: If during the check when the machine is turned on there is a problem with the electro-brake, the acoustic
signal will sound continuously for ten seconds during which the symbols will ash alternately on the control display
shown in the image (Fig. 22). To solve the problem, contact an authorised technical assistance centre. With the alarm
active, the machine can not work on surfaces with an inclination greater than 2%.
