The Cat E2 Series Mini Hydraulic Excavators are designed to carry on the solid performance of their E Series predecessors, while adding even greater value for the customer. The new High Definition Hydraulic (HDH) System, redesigned operator station and enhanced digital control panel specially designed for Cat Mini Excavators – COMPASS (Complete, Operation, Maintenance, Performance And Security System) – are all standard features that improve performance and increase value.
Features & Benefits
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 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.
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.
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.
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.
AUTOMATIC TWO SPEED
With the standard automatic two speed feature, the machine will automatically balance high speed and torque travel requirements based on jobsite conditions to give the operator the optimum speed and control.
PASSCODE PROTECTED SECURITY SYSTEM
A standard anti-theft device now comes on every E2 Series compact excavator. A five digit alphanumeric password is required to start the machine when the anti-theft feature is enabled.
ADJUSTABLE AUXILIARY WORK TOOL FLOW CONTROL
Both the standard main line and optional secondary auxiliary hydraulics can be adjusted on a scale of 1–15 through a few buttons on the control panel. Adjust the flow to your different tools with a simple push of a button.
With the auxiliary hydraulics on the right hand joystick, just hold the roller switch at the desired flow rate and direction for 2.5 seconds and the machine will maintain that flow rate until it is turned off.
Change the operating pattern between excavator and backhoe with a simple press of a button from the comfort of the cab. Exclusive push button pattern changer is safe and easy.
MAINTENANCE AND PERFORMANCE INFORMATION
Easily keep track of various maintenance and performance parameters of your machine. Reset the maintenance intervals and ensure the machine is receiving proper care maximizing the life of the machine.
This 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 jobsite 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.
The standard rubber track lets you work on multiple surfaces such as grass, pavement or stone without damaging the surface or machine.
STEEL TRACK OPTION
Optional steel track is available for harsh conditions such as demolition. The extra weight of the steel tracks generally provides better stability when digging over the side of the machine.
SIMPLE DOZER CONTROL WITH FLOAT FUNCTION
The dozer function is pilot controlled from inside the cab, providing smooth, proportional operation. The standard float function is enabled by pushing the lever fully forward into the detent position.
EXCELLENT BLADE VISIBILITY
Visibility to the blade is excellent in any position, allowing the blade to be positioned behind the operator and away from the front linkage for better access when back dragging and finishing in tight areas.
The E2 Series is available with a mechanical pin-grabber or a hydraulic pin-grabber quick coupler option. The coupler design uses a wedge to keep the tool secure to the coupler, reducing wear and maintaining a tight fit through the life of the coupler.
STANDARD THUMB READY STICKS
Machines come standard with stick mounted brackets, ready to fit a hydraulic thumb for even greater machine versatility. A factory installed bracket and relief valve make hydraulic thumb installation simple and cost-effective.
Extended service intervals, durable components, and ease of service access points decrease your owning and operating costs while increasing your long-term value.
