ENGINE

EACH OF THE E2 MODELS IS EQUIPPED WITH THE ENGINE SOLUTION TO BEST SUPPORT THE POWER AND PERFORMANCE REQUIRED BASED ON THE WEIGHT CLASS AND APPLICATION. ALSO, STANDARD FEATURES LIKE AUTO IDLE OFFER CONSISTENT LOWER ENGINE SPEEDS TO INCREASE ENGINE LIFE AND OFFER FUEL SAVINGS. SMART TECHNOLOGY IS A NEW FEATURE OF THE 303.5E2. THROUGH THE INTEGRATION OF THIS TECHNOLOGY WITH THE U.S. EPA TIER 4 FINAL 23.5 HP (17.6 KW) ENGINE, THE MACHINE IS ABLE TO MEET AND EXCEED PERFORMANCE OF THE PREVIOUS GENERATION 303.5E. ADDITIONALLY, TESTING ON THE 303.5E2 REVEALED AN 8% FUEL ECONOMY IMPROVEMENT AND 7% GREATER EFFICIENCY OVER THE E SERIES.

AUTOMATIC TWO SPEED

WITH THE STANDARD AUTOMATIC TWO SPEED FEATURE, THE MACHINE WILL AUTOMATICALLY BALANCE HIGH SPEED AND TORQUE TRAVEL REQUIREMENTS BASED ON JOB SITE CONDITIONS TO GIVE THE OPERATOR THE OPTIMUM SPEED AND CONTROL. THE MACHINE CAN BE PUT IN LOW GEAR IF SLOWER TRAVEL IS DESIRED WHILE IN TIGHT CONDITIONS.

COMFORTABLE WORKING ENVIRONMENT

THE HIGH QUALITY SUSPENSION SEAT, 76 MM (3 IN) RETRACTABLE SEAT BELT, EASY TO ADJUST ARMRESTS, AND ERGONOMIC LAYOUT PROVIDE SUPERIOR COMFORT AND REDUCE OPERATOR FATIGUE. THE NEW INTERLOCKING FRONT WINDOW SYSTEM, UPDATED OPERATOR INTERFACE AND 100% PILOT CONTROLS PROVIDE A BEST-IN-CLASS OPERATOR STATION AND CUSTOMER VALUE.

JOYSTICK CONTROLS

THE BOOM SWING AND AUXILIARY HYDRAULIC FUNCTIONS ARE LOCATED AT YOUR FINGERTIPS PROVIDING SMOOTH, EASY OPERATION. THEY ALSO ELIMINATE FOOT PEDALS AND FREE UP THE FLOOR FOR MORE ROOM FOR THE OPERATOR’S FEET. 100% PILOT CONTROLS PROVIDE CONSISTENT FLOW AND PRESSURE THROUGHOUT THE LIFE OF THE MACHINE. THIS ALLOWS ALL CONTROLS TO BE LOCKED OUT WHILE STARTING THE MACHINE.

POWERFUL DIGGING, PRECISE CONTROL

THE NEW HIGH DEFINITION HYDRAULIC (HDH) SYSTEM IN THE E2 MACHINES PROVIDES A LOAD SENSING AND FLOW SHARING CAPABILITY LEADING TO OPERATIONAL PRECISION, EFFICIENT PERFORMANCE AND GREATER CONTROL. BY COMBINING VARIABLE PUMP EFFICIENCY, OPEN CENTER VALVE SIMPLICITY, AND A SIMPLE ARCHITECTURE THE VALVE ACHIEVES CONTROLLABILITY. THE SIMPLE VALVE ARCHITECTURE REDUCES HEAT WHICH LEADS TO A REDUCTION IN HYDRAULIC INSTABILITY AND IMPROVED OVERALL EFFICIENCY.

200 DEGREE BUCKET ROTATION

INDUSTRY LEADING BUCKET ROTATION OF OVER 200 DEGREES PROVIDES GREATER MATERIAL RETENTION DURING TRUCK LOADING. IT ALSO ALLOWS FOR EASIER VERTICAL WALL DIGGING WITHOUT REPOSITIONING THE MACHINE.

COMPACT RADIUS

THE COMPACT RADIUS DESIGN GIVES GREATER MACHINE VERSATILITY AND THE CAPABILITY TO WORK WITHIN CONFINED AREAS. THIS ALLOWS THE OPERATOR TO CONCENTRATE ON THE WORK BEING DONE WITHOUT HAVING TO WORRY ABOUT DAMAGING THE BACK OF THE MACHINE OR OTHER JOB SITE OBSTACLES.

ZERO TAIL SWING

THE 303.5E2 CR MODEL FEATURES A ZERO TAIL SWING DESIGN. ON THIS MODEL, THE RADIUS OF THE UPPER BODY STAYS ENTIRELY WITHIN THE WIDTH OF THE UNDERCARRIAGE.
