Air Brake Filter Cleaning
Filtered air is supplied from the tractor. Additional air
filtering is obtained through two air filters on the drill.
There is an air filter (1) in both the supply line and the
service line. The filters trap any debris introduced
during connection and disconnection.
Clean filters seasonally, more often in dusty
conditions.
1. Move the drill to a sheltered area, to prevent
unfiltered dust from entering the opened air
system.
2. Stop the tractor engine, apply the tractor parking
brake, and take the key with you.
3. Apply the parking brake on the drill.

left-hand side of the machine near the ladder (3).
Push the button all the way in to empty the air
reservoir. This will release the air from the air
brake system.
