8. There are three fittings in the brake system that
must be bled. Open each fitting one at a time in
the order shown below. Open each fitting just
enough to allow air to escape while the system is
pressurized, but not enough to allow air to enter.
When the fluid at each fitting is free of air, close
the fitting.
a. Inlet fitting (3) on the accumulator (4).
b. Inlet fitting on the left brake chamber (5).
c. Inlet fitting on the right brake chamber (6).
9. Use the hairpin in the emergency valve to rotate
the shaft counterclockwise to the working
position. This will open the brake system to
pressure from the tractor.
10. Start the tractor engine. Apply the trailer brakes
for five seconds to charge the emergency brake
accumulator. Stop the tractor engine.
Air Brake Reservoir Draining
Before storage, or daily in humid operations, drain
water from the air reservoir tank (1). Draining the air
reservoir can prevent rust inside the tank and rust
contamination of the brake valve system.
1. Chock the cart tires.
2. Pull the ring (2) to open the drain valve. Hold the
drain valve open until no water flows.
3. Release the drain valve.
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.
