Hydraulics
Power to move more dirt, rock, and debris with speed and precision
Hydraulic Horsepower
Hydraulic horsepower is the actual machine power available to do work through implements and work tools. It’s much more than just the engine power under the hood – it’s a core strength that differentiates Cat® machines from other brands.
Main Control Valve and Auxiliary Valves
The 349E uses a highpressure system to tackle the toughest of work in short order. The 349E uses a redesigned sideby side main control valve, which allows for auxiliary hydraulic lines and valve conigurations to be simpliied for greater reliability.
Return Filter
The return ilter is a capsuletype design with a cartridge inside. Unlike many competitors’ offerings, the Cat cartridge features a handle to help remove and change oil without spillage or contamination. A sensor attached to the ilter warns the operator if it is full or exceeds a certain pressure level.
Swing Priority Circuit
The swing priority circuit on the 349E uses a new electric valve that’s operated by the machine’s improved Electronic Control Module (ECM). Compared to using a hydraulic valve, an electric valve allows for more inely tuned control, which is critical during material loading.
Electric Boom Regeneration Valve
A new electric boom regeneration valve minimizes pump low when the boom lowers down, which improves fuel economy. It is optimized for any dial speed setting being used by the operator, which in turn aids controllability and enhances component durability.
Stick Regeneration Circuit
The 349E regenerates the low of oil from the rod end of the stick cylinder to the head end of the stick cylinder during lowload, stickin operation – an approach that saves energy and expense.

Operator Station
Comfort and convenience to keep people productive
Seats
A new seat range includes mechanical, air suspension, heated, and air cooled options. Each option includes a reclining back, upper and lower seat slide adjustments, and height and tilt angle adjustments to meet operator needs for comfort and productivity.
Controls
The right and left joystick consoles (1) can be adjusted to meet individual preferences, improving operator comfort and productivity during the course of a day.
With the touch of the button, onetouch idle reduces engine speed to help save fuel; touch it again or move the joystick and the machine returns to normal operating level.
The optional heavy lift mode increases machine system pressure to improve lift – a nice beneit in certain situations. Heavy lift mode also reduces engine speed and pump low in order to improve controllability.
Monitor
The 349E is equipped with a new LCD (Liquid Crystal Display) monitor (2) that’s 40% bigger than the previous model’s
with higher resolution for better visibility. In addition to an improved keypad and added functionality, it’s programmable
1 to provide information in a choice of 42 languages to support today’s diverse workforce.
A new “Engine Shutdown Setting” accessible through the monitor allows owners and operators to specify how long the machine should idle before shutting down the engine, which can save signiicant amounts of fuel.
In addition, the monitor serves as a display for the optional rearview camera. Up to two different camera images can be displayed on the screen.
MP3-Ready Radio and Power Supply
The standard radio is equipped with a new auxiliary audio port for MP3 players. Two 12volt power supply sockets are located near key storage areas for charging.
Storage
Storage spaces are located in the front, rear, and side consoles. New space near the auxiliary power supply holds MP3 players and cell phones. The drink holder accommodates large mugs with handles, and a new shelf behind the seat stores large lunch or toolboxes.
Automatic Climate Control
The climate control system features ive air outlets with positive iltered ventilation, which makes working in the heat and cold much more pleasant.

Engine
Reduced emissions, economical and reliable performance
Cat® C13 ACERT™ Engine
The Cat C13 ACERT engine delivers more horsepower using less fuel than the previous series engine.
Emissions Solution
The C13 ACERT engine is equipped to meet current U.S. Tier 4 Interim regulations. Driven by customer input,
Cat’s aftertreatment regeneration solution ensures the machine works as normal with no operator intervention needed.
The machine comes with two programmable modes of operation: automatic and manual regeneration.
In automatic mode, the machine starts the regeneration process once the iltering system reaches a certain level and conditions are optimal. The system will not interrupt the work process and can regenerate during machine operation.
Manual mode enables the operator to override the automatic mode. With a touch of a button (1) inside the cab, this mode allows the operator to move the machine from lammable or heatrestricted areas before initiating the regeneration process.
Bio Diesel-Ready Fuel System
The Cat C13 ACERT engine is equipped with a mechanically actuated, electronically controlled unit injector (MEUI) fuel system that includes a new electric priming pump and threelayer fuel hose to allow the use of bio fuel up to B20 (bio fuel 20% mixture).
Cooling System
The highambient cooling system features a sidebysidemounted radiator and oil and air coolers for easy cleaning.
Speed and Power Control
The new E Series features isochronous speed control to maintain a constant speed – regardless of load – to improve fuel economy. Three different power modes are offered: high power, standard power, and economy power. The operator can easily change between modes through the monitor or console switch to meet the needs for the job at hand – all to help manage and conserve fuel.

Structures and Undercarriage
Built to work in rugged environments
Frame
The upper frame includes new reinforced mountings to support a new RollOver Protective Structure (ROPS) cab; the lower frame is reinforced to increase component durability.
Undercarriage
Fixed and variable gauge long undercarriage systems are available to support various work applications.
Heavyduty track rollers, precisionforged carrier rollers, pressit pin master joints, and enhanced track shoe bolts improve durability and reduce the risk of machine downtime and the need and cost to replace components.
A new segmented threepiece guiding guard is now offered to maintain track alignment and improve performance in multiple applications.
A redesigned motor housing prevents mud packing and debris buildup around seals.
Counterweights
The standard 9.0 mt (9.9 t) counterweight maintains large lifting capacity and excellent stability. A counterweight with removal device is available as an attachment to reduce the time required in preparation for transport. Both counterweights bolt directly to the main frame for added rigidity and feature an integrated housing for the new rearview camera option.

Front Linkage
Made for high stress and long service life
Booms and Sticks
The 349E is offered with a range of booms and sticks.
Each is built with internal bafle plates and stressrelieved for added durability, and each undergoes ultrasound inspection to ensure quality and reliability. Large boxsection structures with thick, multiplate fabrications, castings, and forgings are used in highstress areas such as the boom nose, boom foot, boom cylinder, and stick foot to improve durability. Also, the boom nose pin retention method is a captured lag design for enhanced durability.
Selections
Two boom types are offered:
HD = Heavy Duty Reach. HD is designed for general excavator applications such as multipurpose digging and loading, and it includes additional steel to make it more durable and better suited for more demanding applications like moving rock or using a hammer.
ME = Mass Excavation. ME is best used for quarry, high volume loading, and other demanding applications. The ME front provides higher digging forces due to the geometry of the boom and stick relationship. Bucket linkage and cylinders are also built for greater durability.

Work Tools
Dig, hammer, rip, and cut with conidence
Work Tools
An extensive range of Cat Work Tools for the 349E includes buckets, hydraulic hammers, multiprocessors, scrap and demolition shears, contractors’ grapples, trash grapples, rippers, and thumbs. Each is designed to optimize the versatility and performance of your machine.
Couplers
Quick couplers allow one person to change work tools in seconds for maximum performance and lexibility on a job site. One machine can move rapidly from task to task, and a leet of similarly equipped machines can share a common work tool inventory.
Cat Center-Lock™ Pin Grabber Coupler
CenterLock is the pin grabber style of coupler and features a patentpending locking system. A highly visible secondary lock clearly shows the operator when the coupler is engaged or disengaged from the bucket or work tool.
Hydraulic Kits
Caterpillar offers ieldinstalled hydraulic kits that
are uniquely designed to integrate Cat Work Tools with Cat excavators. Hoses and tubes are premade, preshaped, and prepainted to make installation quick and easy.

Buckets
Cat buckets are designed as an integral part of the 349E system and feature new geometry for better performance. The leading edge has been pushed forward, resulting in more eficient illing and better operator control for greatly improved productivity.
Wear coverage in the corners and side cutter and sidebar protector coverage are improved; a new lift eye design accepts a wide range of shackle sizes.
All beneits are captured in a new bucket line with a new bucket naming convention. Following are the types offered:
General Duty (GD)
GD buckets are for digging in lowimpact, lowabrasion material such as dirt, loam, and mixed compositions of dirt and ine gravel.
Heavy Duty (HD)
The most popular bucket style, HD buckets are a good starting point when digging conditions are not well known like a wide range of impact and abrasion conditions that include mixed dirt, clay, and rock.
Severe Duty (SD)
SD buckets are for higher abrasion conditions such as well shot granite and caliche.
Extreme Duty (XD)
XD buckets are the new standard for highabrasion conditions, including high quartzite granite.
Specialty Buckets
In addition to the four levels of bucket durability categories, several specialty buckets are available for the 349E, each with a different purpose:
•Ditch cleaning for cleaning ditches, slope grading, and other inish work
•Center-Lock Pin Grabber Performance for maximum digging performance while keeping the versatility and convenience of a coupler
•Power for use in abrasive applications where breakout force and cycle times are critical
•Wide tip for lowimpact material where leaving a smoother loor and minimal spillage are necessary
