MACHINE DESCRIPTION
This manual refers the front, rear, left and
right of the machine as seen when sitting in
the operator’s seat with the dozer blade
visible to the front.
DESIGNATED OPERATIONS
Use this machine primarily for the following
operations:
• Excavation
• Digging ditches
• Digging side ditches
• Leveling
• Loading
FEATURES
• Adopting the auto-idle enables less fuel
consumption
• Equipping the auxiliary 1st and 2nd lines
with a flow rate control mechanism
• Configuring the auxiliaries of 2nd, 3rd
(high-pressure type) and 4th.
• Legible instrument cluster with a 5-inch
color LCD
• Smaller rear slew radius, smaller turns
(stability is retained)
• Installing the ROPS certified large cab (with
front sash assist)
• Adopting the larger engine hood and right
side cover allows easier maintenance
• Optional angle dozer blade with a float
BREAK-IN PERIOD
When the machine is new, operate the
machine for the first 100 hours (as indicated
on the hour meter) by following the
instructions below.
Using a new machine without a break-in
period will lead to quicker deterioration of
machine performance and may shorten the
machine’s service life.
• Sufficiently warm up the engine and
hydraulic oil.
• Avoid heavy loads and rapid operations.
Operate with a load of about 80% the
maximum load.
• Do not abruptly start up, accelerate,
change directions, or stop unless
necessary.
