[. . . ] Large working space is not required for the machine. Protrusion from track: PC228US 910 mm 3'0" PC228USLC 770 mm 2'6" PC200 1640 mm 5'5" Logging road width approx. 4 m 13'1" Protrusion from track: PC228US 280 mm 11. 0" PC228USLC 140 mm 5. 5" PC200 1350 mm 4'5" Logging and forest roadwork Since the protrusion of the rear portion of the upper structure is kept minimum, there is less possibility of the counterweight hitting against a tree or a slope, allowing the operator to operate the machine at ease. Furthermore, large Road and Bridge Work digging height facilitates a slope finishing work large drawbar pull assures smooth and powerful traveling even on rough terrain. 3990 mm 13'1" Demolition The machine needs less working space and can perform efficient demolition work since it has large and ample digging height. Lane width 4. 5 m 14'9" 6 7 PC228US-3E0 H Y D R A U L I C E X C AVAT O R HYDRAULIC EXCAVATOR PC228US-3E0 0 WORKING ENVIRONMENT PC228US-3E0 cab interior is spacious and provides a comfortable working environment. . . Safety Features Sturdy Cab Protects the Operator from Falling Objects Fully press mold cab meets the ISO head guard standard of OPG top guard level 1. The cab is produced by means of press integral molding and has a strengthened frame structure with improved total rigidity, featuring excellent durability and impact resistance. Combined with the adoption of inertiareel seat belt, the cab protects the operator from falling objects. Emergency Escape Hammer The cab is equipped with a emergency escape hammer to be used for breaking the rear window glass in case of an emergency. Large Comfortable Cab Multi-Position Controls The multi-position, PPC (pressure proportional control) levers allow the operator to work in comfort while maintaining precise control. A double-slide mechanism allows the seat and controllers to move together or independently, allowing the operator to position the seat and controllers for maximum productivity and comfort. Large Side-view, Rear, and Sidewise Mirrors Enlarged left-side mirror and addition of rear and side mirror allow the PC228US-3E0 to meet the new ISO visibility requirements. Start-to-travel Alarm An alarm is installed as a standard equipment to give other workers a warning that the machine will start to travel. Pump/engine Room Partition Pump/engine room partition prevents Low Cab Noise Cab is highly rigid and has excellent sound absorption ability. Defroster function keeps cab glass clear. 9 PC228US-3E0 H Y D R A U L I C E X C AVAT O R HYDRAULIC EXCAVATOR PC228US-3E0 0 MAINTENANCE FEATURES Easy Maintenance Komatsu designed the PC228US-3E0 to have easy service access. We know by doing this, routine maintenance and servicing are less likely to be skipped, which can mean a reduction in costly downtime later on. Here are some of the many service features found on the PC228US-3E0: Maintenance Costs Reduced Long Replacement Interval of Hydraulic Oil and Filter/Engine Oil and Filter High performance filters are used in the hydraulic circuit and engine. Longer hydraulic oil, hydraulic oil filter, engine oil and engine oil filter element replacement intervals significantly reduce maintenance costs. 1 2 11 Central partition 10 Control valve Right front side cover Hydraulic tank Fuel tank 3 4 7 6 Engine Pump 9 Right rear side cover 8 15 14 Engine oil & engine oil filter Hydraulic oil Hydraulic oil filter LCD Multi-function Color Monitor Indicators 1 2 3 1 Working mode 2 Service meter 3 Travel speed 4 Engine water temperature gauge 5 Hydraulic oil temperature gauge 6 Fuel gauge 7 Swing parking brake 8 Preheater 9 Wiper 10 Auto-decelerator 11 Power Max.

The Komatsu exclusive system identifies maintenance items, reduces diagnostic times, indicates oil and filter replacement hours and displays error codes. Maintenance display of the EMMS multi-color monitor (Example) Normal display Maintenance time display Engine oil replacement display Easy Radiator Cleaning Since radiator and oil cooler are arranged side-by-side, it is easy to clean, remove and install them. Continuous Machine Monitoring System When turning starting switch ON, Check-before-starting item and caution items appear on the liquid crystal panel. If abnormalities are found, a warning lamp blinks and a warning buzzer sounds. The continuous machine condition checks help prevent the development of serious problems and allows the operator to concentrate on the controls. Abnormal information & checking function display of the EMMS multicolor monitor (Example) Battery charging abnormal display Error code display Display for night work Equipped with the Fuel Pre-filter (with Water Separator) Removes water and contaminants in the fuel to prevent fuel problems. Abnormally Display with Code When an error occurs during operation, a user code is displayed. When an important user code is displayed, a caution lamp blinks and a warning buzzer sounds to prevent the development of serious problems. Oil Maintenance Function When machine exceeds oil or filter replacement time, the oil maintenance monitor lights to inform operator. Washable Floor The PC228US-3E0's floor is easy to keep clean. The gently inclined surface has a flanged floormat and drainage 10 holes to facilitate runoff. Trouble Data Memory Function Monitor stores abnormalities for effective troubleshooting. 11 PC228US-3E0 H Y D R A U L I C E X C AVAT O R PC228US-3E0 H Y D R A U L I C E X C AVAT O R RELIABILITY FEATURES High Rigidity Work Equipment Boom and arms are constructed of thick plates of high tensile strength steel.
