Parking Brakes
(see Parts Manual section: Parking Brakes)
(see Operator Manual section: Brake Operation)
Refer to Figure 113 and Figure 114
Cable-operated parking brakes engage and release
independently of the service brake system. There is one
operating handle on each side frame of the drill, at the
rear of the front hopper.
The parking brakes themselves are independent sys-
tems for each side of the drill. None of these three brak-
ing systems can engage or release any of the others.To
engage drill parking brakes, pull each handle, on each
side, to the rear, until the over-center action holds the
brake engaged.
To release drill parking brakes, pull each handle, on each
side, outward from drill, and release forward.
If the handle fails to remain in the engaged position,
there is insufficient tension on the brake cable. If the han-
dle requires excess effort, or cannot be pushed into the
engaged position, there is too much tension. Rotate the
grip end
of the handle to adjust cable tension.
Brake Roll-Away Hazard:
Set manual drill parking brake handle before unhitching drill.
Block tires for extra safety in case brake system is tampered
with or is not in working order. Parking jack is not sufficient
restraint for a drill parked on un-level ground. An unsecured
drill could roll away, causing an accident resulting in death,
injury and substantial property damage.
Both versions of the trailer brake system to the tractor are
spring-release on the air drill. Unless the drill parking brake is
set, drill braking is released shortly after unhitching the drill.
