wheel cannot rotate freely, it is forbidden to use, so the hand brake pull lock mechanism
needs to be readjusted to make the wheel hub rotate freely, otherwise the friction disc will be
sintered in a short time and the brake will fail.

Fuel quantity of Integrated electrical bridge
Model: HELI dedicated 85w/90
Brake side: 1.6-1.7L
No brake side: 1-1.1L
Every 10-15 days, it is necessary to check the integrated electrical bridge for no oil
leakage, if necessary to find out the cause, and timely fill oil.
Replace gear oil of wheel side reducer every 1200 hours, oil type should be consistent
with requirements.
If the dust and oil in the working environment are large, dust and oil on the motor
surface need to be cleaned regularly to ensure the normal heat dissipation of the motor.

Brake maintenance
Wet braking is a completely closed structure, which is maintenance free and has a
design life of
≥
6000h. When the braking failure occurs, relevant investigations should be
conducted to further ensure the cause.
