Easy Maintenance
Large Capacity Air Cleaner
Large capacity air cleaner is
comparable to that of larger machines.
The larger air cleaner can extend air
cleaner life during long-term operation
and prevents early clogging and
resulting
power
decrease.
Reliability is
improved by a
new seal
design.
Long Work Equipment Greasing
Interval
High quality BMRC bushings and resin
shims are optionally available for work
equipment pins excluding bucket,
extending greasing interval to 500 hours.
Large Fuel Tank Capacity
Large fuel tank capacity extends
operating hours before refueling. Fuel
tank is treated for rust prevention and
improved corrosion resistance.
Long-life Oil, Filter
Uses high-performance
filtering materials and
long-life oil. Extends the
oil and filter replacement
interval.

Easy Access to Engine Oil Filter
and Fuel Drain Valve
Engine oil dipstick and fill, and fuel
filter are mounted on same side to
improve accessibility. Fuel drain valve
are remotely mounted to improve
accessibility.
Fuel Drain Valve
Easy Radiator Cleaning
Since radiator and oil cooler
are arranged side-by-side, it
is easy to clean, remove
and install them.
