User manual CATERPILLAR 304D CR BROCHURE

[. . . ] Powerful digging forces, fast cycle times and increased stability lead to more production, helping you get more done and improve your bottom line. Operator Station Comfortable Working Environment Superior comfort to keep you productive throughout the work day. Spacious and comfortable operator station with excellent visibility and legroom keeps the operator comfortable and reduces fatigue. Standard features include: · · · · Reclining suspension seat with adjustable wrist rests. Pilot operated controls on all services including travel levers and dozer functions. Two post canopy design for better visibility to the work area. [. . . ] The D-Series models feature an engine kill switch conveniently located in the cab and accessible from ground level. Automatic Two Speed With the standard automatic two speed feature, the machine will automatically balance high speed and torque travel requirements based on the conditions to give the operator the optimum speed and control. The machine can be put in low gear if slower travel is desired while in tight conditions. 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 having to reposition the machine. 4 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 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 job site obstacles. On the 305D CR and the 305. 5D CR, the upper body stays within 140 mm (5. 5 in) of the undercarriage. Zero Tail Swing New to the D-Series, the 303. 5D CR and the 304D 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. 5 Coupler and Work Tool Options Couplers New coupler design and multiple work tools increase versatility. The D-Series couplers have a new design with a choice of either a mechanical pin-grabber or the new hydraulic pin-grabber quick coupler option. The new 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. The new hydraulic coupler option allows the operator to change tools without leaving the comfort of the cab. Hydraulic quick coupler lines are available from the factory as an option. Wide Range of Work Tools A wide range of Cat Work Tools have been designed specifically 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 Hydraulic Hammers Augers Thumbs (not available in all regions) Vibratory Compactors Shears (boom mounted on 305D CR/305. 5D CR only) Quick Coupler Standard Thumb Ready Sticks (optional in Europe) 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. Standard Auxiliary Lines and Accumulator One-way and two-way auxiliary lines (combined function), including quick connections, are fitted as standard equipment so the machine comes ready to work. A standard accumulator allows for auxiliary pressure to be released, making connecting and disconnecting work tools safer and easier. 6 Dozer Blade Standard dozer blade maximizes productivity. 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. Cleanup and backfilling 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 finishing 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 backfilling so you can finish the job faster. All functions of the blade are controlled with one joystick using a proportional roller switch for the angle function. 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 304D 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. 7 Simplified service and maintenance save you time and money. Serviceability Easy Service Convenient service features make maintenance easy, reducing your downtime: · Lifting side hood allows access to air filter, main implement valve, 1-way/2-way auxiliary flow selector, accumulator, fuel filter and hydraulic tank. This eliminates the need to lift the cab when maintaining and servicing the machine.
