Machine Travel Controls
•
Levers and controls should return to the neutral position when they are
released.
• Make sure that all of the controls are in the neutral (middle) position before
starting the engine.
•
Operate the controls gradually and smoothly. Excessive speed and quick control
movements without regard for working conditions could cause an unsafe
situation.
• Make sure to maintain your grip on both of the hand grips any time the machine
is in motion.
Due to the spring tension system built into the track drive system as a safety mechanism, the
machine can be put into an extreme situation during which the drive sprocket will bypass the
rubber track guide holes causing a popping noise, called “cogging”. This situation is part of
the track drive systems safety design, and indicates that this portion of the safety system is
functioning properly.
The “cogging” condition is most likely to occur while operating in a reverse direction pulling
a heavy load, and during the first 50 hours of track usage. It is caused by the tension spring
being fully compressed due to high track load.
If a cogging condition occurs, immediately stop machine travel and auxiliary functions and
reverse travel direction slightly to de-compress track tension. Continued cogging will cause
the track drive sprocket to seat into the rubber track incorrectly, and cause damage to the
track. If cogging occurs, stop travel function and check for and remove any debris or foreign
matter in the drive system, check track for proper tension as shown in Section 4 of this
manual, and resume operation.
