excavator. A ve digit alphanumeric password is required to start the
machine when the anti-theft feature is enabled. There is a master
password and up to ve user passwords can be created by the
ownerif desired.

Keep your machine safe on a busy job site by locking it when you
arenotaround

Adjustable Auxiliary Work Tool Flow Control

The ESeries machines now have simple adjustability of the ow
going down the boom and stick to the work tool. 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 ow to your different tools with a simple push of a button

6

UNLOCK the new features and experience the
value of the exclusive COMPASS control panel
onthe new ESeries compact excavators

Economy Mode

This feature allows your machine to be set in a more economical
power setting with a simple push of a button. While operating in
this mode, the machine will maintain excellent performance levels
while saving up to 20%fuel through a slightly lower engine setting.

Save money with the new ESeries compact excavators

Continuous Flow

Once this feature is enabled through a button on the monitor, the
new ESeries machines can run in continuous ow mode. With the
auxiliary hydraulics on the right hand joystick, just hold the roller
switch at the desired ow rate and direction for 2.5 seconds and
the machine will maintain that ow rate until it is turned off.

Maintain hydraulic ow to your tools at any ow and in any
direction withthe simple push of a button

Pattern Changer

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

7

Compact Radius, Zero Tail Swing

Work in the tightest areas

Compact Radius

The compact radius design gives greater machine versatility and the
capability to work within conned 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. On the
305E CR and the 305.5E CR, the upper body stays within 140 mm (5.5 in)
ofthe undercarriage.

Zero Tail Swing

New to the E Series, the 303.5E CR and the 304E CR models feature a zero
tail swing design. On these models, the radius of the upper body stays
entirely within the width of the undercarriage.

8

Undercarriage Stability and Durability

Rubber Track – 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. (Not available on the 304E CR.)

Rubber Pads – Optional rubber pads can be attached to the steel track to prevent damage to paved surfaces and minimize noise
andvibration during travel with the steel track system. This option provides the maximum overall stability.

9

Dozer Blade

Maximize your productivity

Simple Dozer Control with Float Function

The dozer function is pilot controlled from inside
the cab, providing smooth, proportional operation.
The standard oat function is enabled by pushing
the lever fully forward into the detent position.
Cleanup and backlling is easier since the
operator does not have to adjust the blade height
duringtravel.

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 nishing
intightareas.

Angle Blade Option

Increase machine versatility with the Cat angle dozer blade.
Builtfor strength and durability, the hydraulic angle blade features
a hardened steel wear edge and good protection to cylinders
and hydraulic lines. The angle blade can be positioned straight
ahead or angled up to 25 degrees to the left or right. This reduces
the number of times required to back up and reposition when
backlling so you can nish the job faster. All functions of the blade
are controlled with one joystick using a proportional roller switch
for the angle function.

10

Coupler and Work Tool Options

Increased versatility with multiple work tools

Couplers

The E 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 t through the life
ofthecoupler.

The hydraulic coupler allows the operator to change tools
without leaving the comfort of the cab.

Wide Range of Work Tools

A wide range of Cat Work Tools have been designed
specically for the Cat Mini Hydraulic Excavators to maximize
machine performance. Available work tools include:

• Buckets (heavy duty and heavy duty capacity)

• Tilting, Ditch Cleaning Buckets
