Multiquip SP706020 Blade Shaft Engage System / Wheel Drive System, To Stop blade shaft rotation

BLADE SHAFT ENGAGE SYSTEM / WHEEL DRIVE SYSTEM

To Re-adjust for full cutting depth:

1.Hold the raise/lower switch in the lowering position and rotate the depth control knob clockwise until the saw is fully lowered.

2. Rotate depth control knob clockwise an additional 1 turn.

To disable the depth stop when it is not needed:

1.While holding the raise-lower toggle switch FORWARD, rotate depth control knob CLOCKWISE until saw is at full depth position.

2. Rotate depth control knob an additional 1-2 turns.

BLADE SHAFT ROTATION — DISENGAGEMENT SYSTEM

The engine MUST be at IDLE when engaging or disengaging blade shaft drive (Figure 30, item 1).

Hydraulic system pressure must be sufficient to enablethebladeshaftengage/disengagefeature. Increasing engine RPM slightly may help facilitate the system pressure necessary to engage the blade shaft drive.

To STOP blade shaft rotation:

Push rocker switch labeled BLADE SHAFT DISENGAGE (Figure 30, item 2).The engine (via the hydraulic lift cylinder) will tilt forward, disengaging the belt drive.

To START blade shaft rotation:

Push rocker switch labeled BLADE SHAFT ENGAGE (Figure 30, item 2).The engine (via the hydraulic lift cylinder) will tilt backward, engaging the belt drive.

WHEEL DRIVE SYSTEM

The 7060 Series features a cable-controlled hydraulic powered gear motor system with infinite Forward-Neutral- Reverse (F-N-R) speed adjustment. This is controlled by the operator through the speed control handle located on the control panel. The saw is designed with a locked axle drive and can travel forward at transportation speeds up to 275 feet per minute.

A bi-directional variable displacement transmission pump powers two hydraulic wheel motors that are directly coupled to the wheels. This design provides vehicle propulsion in both forward and reverse depending on the position and direction of movement of the F-N-R control handle. The wheel drive system also provides dynamic braking action.

Figure 31. F-N-R Control

Refer to Figure 31.

■To increase the forward speed, slowly move the control handle FORWARD.

■To decrease the forward speed, pull the control handle

BACKWARD.

■When the control handle is in the Neutral position the saw will have neither a forward nor reverse motion.

■As the control handle is passed backward through the neutral position the saw will start to move in REVERSE. Reverse speed is also controlled by the position of the control handle.
