MACHINE COMPONENTS
The Pitbull consists of six (6) major components as shown in Figure 2. The following sections
describe each of these components in detail.
1. Carriage
2. Milling unit
3. Milling unit holder
4. Rail
5. Rail alignment clamp
6. Metal chip container
CARRIAGE
The carriage precisely transmits the milling unit along the rail at operator-controlled speed. The
carriage and rail are a set. DO NOT REMOVE THE CARRIAGE FROM THE RAIL. The carriage
can only be moved when the milling unit is connected and the main motor is running. The major
carriage components and control mechanisms are called-out in Figure 3.

The milling unit switch (1.6) consists of a green START button (I), a red STOP button (O) and an
overload indicator light. The indicator flashes when the main motor is operating near overload. The
carriage direction switch has three (3) positions - forward, reverse, and stationary.
