Cab
A large, spacious cab provides operator comfort and improved visibility. Joystick controlled swing boom and auxiliary switches clear space on the floor giving the operator plenty of foot and leg room. An intuitive cab layout for ease of operation reduces operator fatigue. Other cab features include:
Air conditioning is standard.
12V power receptacle for charging cell phones.
A reclining air suspension seat with adjustable armrests.
Storage space for literature and cup holder.
Low effort joystick controls designed to match the operator’s natural wrist and arm positions. Consoles can be adjusted independently of the seat for maximum comfort.
Overhead skylight improves visibility and can be opened to create air flow.
Upper front windshield opens and easily stores on the roof above the operator with an automatic latching mechanism.
All functions are fully pilot operated lowering owning and operating costs.
Pattern control changer is located under the floor mat.
Operator Station
Simple, easy operation allows the operator to focus on production. »Learn More
Compact Radius Design
The compact radius design provides greater versatility and capability to work within confined areas. The radius of the upper body stays close to the width of the undercarriage allowing the operator to concentrate on the work at hand, rather than the tail swing of the machine.
Cab door slides open taking up less space than a hinged door. When working in tight areas this allows for safer ingress and egress. This design maintains the machine’s compact dimensions reducing the risk of damage.
Jobsite flexibility with a reduced risk of damage and less stress for the operator add up to higher rates of productivity.
Smooth responsive hydraulics give the level of control demanded by the customer in any application, from fine grading and dozing to backfilling. Powerful bucket and stick digging forces combined with fast cycle times result in world class productivity and performance. Automatic two speed function improves jobsite maneuverability with precise control by balancing travel speed with the torque needed for turning and travelling on inclines. Dozer blade float function enables easy ground levelling for landscaping and finish grade applications as well as more efficient jobsite clean-up. Economy mode can be selected with the in-cab LCD monitor and provides better fuel efficiency in a platform well suited for less experienced operators.
Controls
Joystick mounted auxiliary and boom swing control enhances machine controllability. Intuitive controls give fine modulation. The levers and dozer function ensure “as new” levels of controllability are maintained throughout the machine life.
Lift Capacity
The new E-Series has industry leading lift capacity matched with outstanding stability in a compact radius package. This provides the on-site versatility required to match the diverse and continually changing needs of the customer.
Stick and Boom
A choice of standard or long, thumb ready sticks enable the customer to match the machine’s digging envelope to their requirements. The boom design maximizes stability and reach with the swing allowing the operator to trench parallel to tracks, dig close to structures and dig a box-section without repositioning the undercarriage.
Performance
Powerful digging with precise control. »Learn More
Engine
Tier 4 Interim/Stage IIIA turbocharged engine gives higher power and maintains strong performance at high altitude.
High digging forces give power through even the most compacted ground with smooth control and responsive hydraulics that deliver productivity that our customers demand.
Load sensing hydraulics optimize the flow of oil for smooth powerful performance and increased fuel economy.
Automatic engine idle lowers engine revolutions when not in use to conserve fuel and lower environmental noise/emissions.
A wide range of work tools have been developed and integrated into the machine design to maximize machine performance and deliver excellent value through high productivity and long life. Cat Work Tools include:
Heavy Duty Buckets
Heavy Duty Rock Buckets
Ditch Cleaning Buckets
Hydraulic Hammers
Augers
Shears
Compactors
Thumbs
Quick Couplers
Couplers
To maximize performance, Caterpillar Pin-Grabber Quick Couplers are compatible with all standard work tools, enabling the operator to simply release one work tool and pick up another, maximizing productivity. The couplers are available in hydraulic and manual versions.
Auxiliary Hydraulics
The combined function high-pressure auxiliary lines and quick connectors are fitted as standard. This auxiliary system includes a diverter valve which provides optimum performance when using a one-way flow (hammer) or two-way flow (auger and thumb) work tool. This feature allows the machine to adapt to a wide variety of applications without re-configuring the auxiliary lines. Versatility is further enhanced with optional hydraulic lines enabling the use of a hydraulic quick coupler. A secondary auxiliary supply circuit for work tools utilizing a rotating or other medium-pressure circuit is also available as an optional attachment.The auxiliary flow can be changed through the in-cab COMPASS display panel. This allows the machine and work tool to provide optimum performance and better match the customer’s application requirements.
Thumbs
Thum ready sticks are standard on the E Series models saving the customer time and money when a thumb is desired. The brackets are already welded in the proper location and relief valves are built in to the main control valve.

Cat work tools are matched to meet your application needs. »Learn More
Track Options
The Cat 308E CR SB offers different track options to choose from allowing the correct machine configuration to suit the job.
Steel Track
The standard track offering is a 450 mm (18 in) triple grouser track. Grease-lubricated track links, split master link and sealed track rollers reduce owning and operating costs. Steel tracks provide optimum stability when lifting over the side. This track is also offered in a 600 mm (24 in) width that provides additional stability and reduced ground pressure.
Rubber Belt
This rubber belt is a traditional mini excavator attachment providing minimal work site damage and the ability to work on multiple surfaces. Construction of this rubber track consists of embedded steel shanks which engage the sprocket and steel cables ensuring rigidity and straight travel.
Rubber Pads
The 450 mm (18 in) wide shoe has four holes that attach rubber pads to the track. This option will prevent damage to paved road surfaces minimizing noise and vibration during travel with a standard steel track system.
Blade Widths
The dozer blade is an important tool used for backfilling trenches, levelling, landscaping, lifting and jobsite clean-up. There are two blade options available. The standard 2320 mm (91 in) blade comes with a replaceable weld-on dozer wear edge and the optional 2470 mm (97 in) blade comes with a replaceable bolt-on dozer wear edge. Both blades are constructed of hardened steel for longer life and extreme dozing ability.
Tie-down Points
Tie-down points are located on the blade and undercarriage for easy and safe machine tie down for transportation.
Robust, reliable and easily serviceable are the key attributes of Cat® Mini Hydraulic Excavators. Full steel body work panels and protected front linkage lines are routed neatly out of the way of potential damage above the boom. Easy access to all daily service points are accessed through the rear hood and side cover. A 500 hour engine oil change period lowers operating costs and the Cat S•O•SSM points assist easy oil sampling for preventative maintenance checks.
Machine Security System
An anti-theft device now comes standard on every E Series machine with the COMPASS system. This security system uses a 5 digit alphanumeric password that is required to start the machine when the anti-theft feature is enabled.
Serviceability
Easy access and minimal maintenance requirements keep your machine on the job. »Learn More
