RG55R Operation • Service • Maintenance

Pre-Starting Inspection

Inspect the hydraulic system for leaks. Check the hydraulic
oil level. Inspect the machine and perform each of the “Daily
Inspections listed in the The Maintenance Manual as needed
before operating this machine.
When using the SOA controls use the supplied teather and
wrist band (pictured below (A)) to prevent operator injury
and possabe property damage.

Starting the Engine

If the key switch is released before the engine starts, wait
until the starter and the engine stops turning before trying
again. This will prevent pos si ble dam age to the starter and/
or flywheel.
If the temperature is extremely cold, it may be necessary to
use cold weather start ing aids. Follow the man u fac tur er’s
recommended procedure when using starting aids.Always
change the hydraulic oil filter at the prop er times. Do not
allow the engine to run with out the filter installed. Failure to

heed either direc tive will result in poor machine performance
and se vere damage.

Start-Up

1. Insert the key (1), and turn the ignition switch to the Run

Position (3) position for 10 seconds.

Note: (2) in the above picture is the Off position.

3. Turn ignition switch to START (4) position. Release the

key upon starting.

Note: If the engine is cold, allow the engine to idle (throttle

in slow position), for a few minute to warm up the engine
before using the machine.

1. Allow the engine to warm up at low idle for two minutes.
2. To warm up the hy drau lic oil, move the engine throttle

to me di um engine speed. Run the engine for about two

minutes while intermit tent ly holding the cutting wheel

raise lever in the RAISE position.

3. Move the engine throttle to the max i mum engine speed. Run

the engine for an addition al two minutes while in ter mit tent ly

hold ing the cutting wheel raise lever in the RAISE position.

This will allow the oil to reach relief pres sure, which

causes it to warm up more rapidly.

4. Cycle all the controls to allow warm oil to circulate

through all the cylinders and lines.

Rear Blade Operation

The RG55R can be started and moved with the Swing Out

Arm (SOA) in the transport position with the operator standing

at the rear of the machine. When the SOA is in the transport

position using the SOA controls, the blade will not function

until the SOA is rotated outward in the operating position. If

the operator is using the remote to operate the machine, the

blade will function normally. This is a built in safety feature to

prevent the operator from accidently crushing his/her feet

while loading or unloading the machine.

NOTICE

The SOA in the transport position should only be used when

moving the machine from stump to stump or loading on a

trailer. The SOA in the transport mode does not allow the

operator a clear line of sight to the cutter wheel.

Operation

NOTICE

To ensure the long life and economical operation of
your stump cutter, we highly recommend that the
operator be well instructed in both the operation
and maintenance of this machine.

NOTICE

DO NOT operate the starter for more than 10
seconds at a time. If the engine does not start, allow
a 60 second cool-down period before re-attempting
to start. FAILURE TO FOLLOW THESE GUIDELINES
MAY CAUSE STARTER MOTOR FAILURE.

UNDERSTAND AND HEED TO THE

INSTRUCTIONS LISTED IN THE SAFTEY

SECTION OF THE MANUAL. IN IT’S ENTIRETY,
