Operation
to another side of the stump to continue removal, or by
filling the hole with chips before continuing.
• In colder weather, the machine may be sluggish at first.
Operating all machine controls, one at a time, will cause
the hydraulic oil to warm up quickly. Operate the machine
lightly until the hydraulic oil is warm.
Stopping the Machine
1. When stopping the machine after normal operation, lower
engine speed to SLOW, and disengage cutter wheel.
2. Cycle each of the hydraulic controls slowly for about 30
seconds each to help the hydraulic components to cool
slowly.
3. Fully retract telescoping tongue, and insert lock-pin.
4. Center and raise the cutting wheel to the fully UP position
and engage the cutting boom transport block. (Or it may
be lowered to the ground if cutting of the same stump
is to be resumed at another time.)
5. Close fully the cutting wheel cross-travel SPEED control
valve.
6. Reduce the engine speed.
Engine Stopping
1. Reduce the engine speed to slow idle.
2. Turn engine start switch to OFF position to stop
the engine. Remove engine start key, and place it in
safekeeping.
Storing the Machine
Preparing the Machine for Storage
Store the machine in a dry protected place. If the machine
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.
Take the weight of the machine off of the tires by resting the
machine chassis on blocks. Do not deflate the tires, however.
Remove Synchronous Belt® belt, and store in wrapped
condition. Spray teeth of Synchronous Belt® belt sprockets
with anti-corrosive agent.
All exposed hydraulic cylinder rods should be coated with
Valvoline Tectyl 506 oil or equivalent. Rusty or pitted cylinder
rods will damage O-Rings and cause leakage.
Lubricate all parts that have grease fittings, as outlined in the
“Maintenance Intervals” section of this manual, to prevent rust.
With the engine OFF, remove any pressure from the hydraulic
cylinders by working the control levers back and forth.
Coat all hydraulic pump control linkage with a light coat of
oil to prevent seizing.
Store the battery inside where temperatures do not drop
below 32° F. Place the battery on wood, not on concrete floor
or steel table. Always keep the battery fully charged. Store
it away from wherever an open flame or sparks might occur.
Information on preparing the engine for storage, are contained
in the “Engine Preservation” section of the Kubota Engine
Operation Manual, shipped with this machine.
If the machine will be stored for a long period of time a diesel
fuel conditioner should be added to the fuel tank.
Check your machine for any worn or broken parts at this
time. By ordering and installing replacement parts now,
you can avoid unnecessary delays when you remove the
machine from storage.
Removing the Machine from Storage
Remove all coverings.
After prolonged storage inspect wheels and brakes. (Refer
to the inspection procedures given in the Trailer Running
Gear - Operation Maintenance Service Manual which was
provided with the machine.) Remove blocks from under the
machine. Check tires for proper inflation.
Lubricate machine entirely, using the instructions provided
throughout all of this manual’s “Maintenance Intervals”
sections.
Information on removing the engine from storage, are
contained in the “Engine Preservation” section of the Kubota
Engine Operation Manual, shipped with this machine.
Wipe off anti-corrosive agent from teeth of Poly Chain belt
sprockets, and remount Synchronous Belt® belt.
Adjust the tension of the Synchronous Belt® belt in
accordance with the instructions contained in this manual’s
“Every 50 Service Hours” section.
Mount the battery and connect the cables to the machine.
Review the machine according to the “Before Starting the
Engine” as found in the “Safety” section, and perform all
maintenance services necessary as described in the “10
Service Hours or Daily” interval of the “Maintenance” section
before starting the engine. Start the machine according to the
“Starting the Engine” and “Pre-Operation Warm-up” sections.
NOTICE
Before stopping an engine that has been operating
