the motor and replace them with new
brushes.

and remove the brake.

Reassembly Notes
13. Inspect the gear oil. If the gear oil is dirty or
some has spilled out, then it must be changed.
Due to the configuration of the gearbox, there is
no way to check the oil level except to empty the
oil and refill it.
When changing the gear oil use 4.6 oz (130 g) of Mobilgear 600 XP 150 or AGIP BLASIA 150 gear oil.
14. Make sure the two vent filters
(37)
are clean and in place, and then insert the motor back into the
gearbox. Take care not to damage the gearbox seal.
15. After reassembling the machine, with the drive wheel off the ground, exercise the drive motor to help
break in the brushes.
