Section 2-25

15.

Use winch to raise boom over relatively

short obstacles only. For taller obstacles,
reverse the machine and swing boom in to
clear obstruction.

16.

Do not position booms more than two feet

above storage cradle when removing from
stored position or returning to stored position
to prevent damage to swing cylinders.

17.

Do not use head rotate function to clear

cutterhead of debris. Best technique is to
clear by hand (after shutting down cutterhead
motor, storing arms in cradle, and turning the
battery disconnect switch to the OFF
position.)

18.

Boom swing cylinder speed is factory set.

Adjustments without prior approval from
manufacturer will void warranty.

19.

Minimum ground clearance of 12" should

be maintained for safety.

20.

Do not 'dump and bump" cutterheads on

the ground to stop their rotation.

21.

Disengage the pump drive using the

clutch (if provided) before starting the engine
in winter and cooler weather. After the engine
is warmed up, reduce the engine speed to
idle before engaging the clutch.

22.

Reduce engine speed slowly to low idle

before energizing or de-energizing
cutterheads.

23.

Be alert at all times - anticipate down-

track conditions and be ready to take
corrective action.

GENERAL OPERATION

1. Make certain all STARTUP procedures have

been followed before beginning working
operations.

2. Make certain all lockups have been removed

and stored (as required).

3. Make certain that the hydraulic oil has been

warmed. See Startup earlier in this section.

4. Engage parking brake.
5. Depress the

11. Angle cutterhead down with a forward angle

of attack (toward front of machine). DO NOT
CUT IN REVERSE! DO NOT ATTEMPT TO
CUT TREES OR SHRUBS MORE THAN 4-
INCHES IN DIAMETER!

12. Maintain ground clearance of 12-inches.
13. Use the

Quick Stop Mode

of braking only

when in 2

or 3

gear and when traveling at

speeds less than 5 mph.

NOTE:  Use winch to raise boom over short
obstacles. For taller obstacles, reverse the
machine and swing boom in to clear obstruction.
In the event that the boom comes  into contact
with a stationary object, the BOOM BREAKAWAY
cylinders will require resetting using the valve on
the 6-station valve bank(s).

Emergency Procedures

1. If a hydraulic hose fails, shut down the

machine immediately, determine cause of
failure, correct condition.

normal range, shut down the engine.
Repair before further operation.

3. Emergency cylinder actuation requires

the electric emergency pump. See
below.

Emergency Pump (Optional)

Depress emergency pump switch in the control
console panel and then operate the required
valve handle to move the attachment as required.
Operate the pump in intervals, for a maximum of
15 seconds at a time. The pump is designed for
emergency use only and should not be used for
extended periods of time.

EMERGENCY STOPPING

The emergency shutdown should be used
only when the engine does not respond to the
normal stop engine procedure or in the event
of an emergency where time is critical.

To shut down the engine and stop all machine
functions, push the EMERGENCY STOP
pushbutton located on any of the control boxes.
