Air Conditioning System

  • Air Conditioning
    The air conditioning system on this machine contains the fluorinated greenhouse gas refrigerant R134a (Global Warming Potential = 1430). The system contains 1.0 kg of refrigerant which has a CO2 equivalent of 1.4 metric tonnes.

QUALITY

The durable hoods and frame and the compact radius design of the 305E2 let you work comfortably and confidently in confined areas. The operator environment includes a high quality suspension seat, easy to adjust armrests and 100% pilot controls which offer consistent and long-lasting controllability.

EFFICIENCY

High Definition Hydraulic System provides a load sensing and flow sharing capability leading to operational precision, efficient performance and greater controllability. Power on Demand provides optimal efficiency and performance the moment you need it. This automatic system ensures fuel efficiency through appropriate engine rating to meet all operational needs as required.

VERSATILITY

Broad range of Cat Work Tools make the Cat Mini Excavator a versatile machine able to meet the requirements of any job site. Over 200 degrees of bucket rotation provides greater material retention during truck loading and easier flat wall digging without having to reposition the machine.

PERFORMANCE

Front shovel bucket orientation provides the operator with more ways to get the job done faster. COMPASS Control Panel is a standard feature that allows the operator to easily adjust auxiliary flows to achieve the optimal work tool performance, activate auto idle for improved fuel efficiency and utilize the security system to ensure protection of valuable assets with the simple touch of a button. The Site Reference System included in the COMPASS monitor provides output from pitch and roll sensors to aid in grading and level trenching. This impacts accuracy and productivity for job site finishing.

SERVICEABILITY

Convenient service and maintenance requirements include ease of access to daily check points, 500 hour engine oil and filter change period, 50 hour grease interval on front implement, S·O·SSM oil sampling valve and overall long term durability.

SAFETY

All Cat Mini Excavators from 3.5 metric tons to 10 metric tons are ROPS, TOPS and Top Guard Level 1 certified and include the Cat Interlock (hydraulic lockout) System, a certified accumulator which allows for auxiliary pressure to be released, making connecting and disconnecting work tools safer and easier, and a travel alarm. All of these safety features are standard on the E2 model lineup (travel alarm optional in Europe).
