These filters are centralized in arrangement for facilitating maintenance.
Hitachi's ETS (Electronic Total control System) can achieve maximum
job efficiency by reducing fuel consumption and noise levels, while
maximizing productivity through the optimization of engine-pump
functions with excellent controllability increasing operator comfort.
• E-P Control (Computer-aided Engine-Pump Control system)
Main pumps regulated by electric engine speed sensing control
system.
• OHS (Optimum Hydraulic System)
6 main pumps and 3 valves system enable both independent and
combined operations of all functions.
• FPS (Fuel-saving Pump System)
FPS minimizes energy loss with superior performance in fine control.
• Auto-idling system for saving fuel and reducing noise.
• Hydraulic drive cooling-fan system for oil cooler.
• Forced-lubrication and forced-cooling pump drive system.
Travel Device
Each track driven by high-torque, axial piston motors, allowing counter
rotation of tracks. 2-stage planetary gear plus spur gears reduction
device. Dual-support-type traction device. Parking brake of spring-set/
hydraulic-released disc type. This parking brake is manually releasable.
CONTROLS

LOADING SHOVEL ATTACHMENTS
Boom and arm are of all-welded, low-stress, high-tensile strength steel
full-box section design. Efficient, automatic level crowding achieved by
one-lever control because parallel link mechanism keeps the bucket
digging angle constant, and level cylinder circuit maintains the bucket
height constant (Auto-Leveling Crowd Mechanism). Auto-lubrication
system for all pins is standard.
