Operation
Stopping The Machine
DUE TO HIGH SPEED LOW-FRICTION ROTATION,
THE CUTTING WHEEL MAY CONTINUE TO ROTATE
UNNOTICED, EVEN AFTER THE ON/OFF SWITCH
HAS BEEN FLIPPED OFF, AND EVEN AFTER THE
ENGINE HAS STOPPED. BE SURE THE CUTTING
WHEEL COMES TO A COMPLETE STOP BEFORE
MOVING THE MACHINE OR LEAVING THE
CONTROLS!
1. When stopping the machine after normal operation,
lower the engine speed to SLOW, and cycle each of
the hydraulic controls slowly for about 30 seconds each
to help the hydraulic com po nents to cool slowly.
2. Flip the cutting wheel ON/OFF Switch down to the OFF
position, stopping the cutting wheel rotation.
3. Stop the cutting wheel rotation quickly by gently lowering
the cutting wheel into the soil.
4. Reduce the engine speed.
Engine Stopping
NOTICE
Before stopping an engine that has been operating
at working load, allow the engine to continue to run
with the throttle midway between slow and fast, for
at least 15 seconds.
1. Reduce the engine speed to IDLE.
2. Turn the engine start switch to the OFF position to stop
the engine. Remove the engine start key.
Parking The Machine
Park on a level surface if possible. If it is necessary to
park on a grade, block the tracks securely. Do not park
sideways on a hill, side-sliding could occur.
• Lower the engine speed control slightly to reduce
engine rpm.
• Center the cutter boom, using the joystick.
• Turn off the cutter wheel by using the cutter wheel
switch on the remote until the cutter wheel comes to
a complete stop.
• Lower the attachment slowly with the boom down switch
on the remote until the cutting wheel rests on the ground.
Machine Storage
Preparing for Storage
Store the machine in a dry protected place. If the machine
32
must be stored outside, cover it with a waterproof canvas
or other material.
Clean all grease, dirt, mud and other foreign matter from the
machine. Wash the machine. Start and operate machine to
help rid it of puddled or excess water. To inhibit rusting, paint
all exposed surfaces.
All exposed hydraulic cylinder rods should be coated with
Valvoline Tectyl 506 oil or equivalent. Rusty or pitted cylinder
rods will dam age O-Rings and cause leakage.
Lubricate all parts that have grease fittings, as outlined in the
"Maintenance Intervals" section of the Maintenance manual,
to prevent rust.
Store the battery inside where temperatures do not drop
below 32° F. Place the battery on wood, not on a concrete
floor or steel table. Always keep the battery fully charged.
DO NOT store where an open flame or sparks might occur.
Check your machine for any worn or broken parts at this
time. By ordering replacement parts now, you can avoid
unnecessary delays when you remove the machine from
storage.
1. Store the machine in a flat place and remove the key
from the engine.
2. Do not store the machine in a place that has flammable
material such as dry grass or straw.
3. When covering the engine for storage, allow the engine
and muffler to cool off completely.
4. Operate the engine after checking and repairing damaged
wirings or pipes, and clearing flammable materials that
may have accumulated while in storage (such as debris
brought in by mice).
Removal from Storage
• Remove all coverings. Wipe excess oil from hy drau lic
cylinder rods.
• Lubricate machine entirely, as instructed in the
"Maintenance Intervals" section of this manual.
• Check the hydraulic hoses and fuel lines for deterioration,
and replace as necessary.
• Tighten all nuts, bolts and hydraulic fittings.
• Replace the hydraulic filter and fuel filter. After prolonged
storage, change the hydraulic oil, engine oil, and fuel (if
a storage aid was not used).
• Mount the battery and connect the cables to the machine.
• Review the machine according to the "Before Start ing the
Engine" as found in the "Safety" section of this manual,
and perform all maintenance services necessary as de-
scribed in the Maintenance section's "10 Service Hours
or Daily" section before starting the engine.
• Start the machine according to the "Starting the Engine"
and "Pre-Operation Warm-up" sections of this manual
