PRODUCTIVITY FEATURES High Production and Low Fuel Consumption Engine The PC300HD-7 gets its exceptional power and work capacity from a Komatsu SAA6D114E engine. Output is 180 kw 242 HP, providing increased hydraulic power and improved fuel efficiency. Hydraulics Unique two-pump system ensures smooth compound movement of the work equipment. HydrauMind controls both pumps for efficient engine power use. This system also reduces hydraulic loss during operation. Four Working Modes Working Mode Selection The PC300HD-7 excavator is equipped with four working modes (A, E, L and B mode). Each mode is designed to match engine speed, pump speed, and system pressure with the current application. This provides the flexibility to match equipment performance to the job at hand. Economy Mode Economy mode is environmentally friendly. Fuel consumption is reduced 20% (compared with PC300HD-7 Active mode) and production is equal to the PC300HD-6 Heavy-duty mode. Power Max Function This function temporarily increases digging force by 7% for added power in tough situations. Lifting Mode When the Lifting mode is selected, lifting capacity is increased by 7% by raising hydraulic pressure. Large Lifting Capacity PC300HD-7 s lateral stability is improved resulting in increased lifting capacity. Larger Arm Crowd Force and Digging Force Provide Increased Production Arm crowd force is increased 10% by improvement of arm cylinder linkage; when Power Max function is applied, arm crowd force is increased by an additional 7%. As a result the total arm crowd force is increased 18%. Bucket digging force when Power Max is applied also increased 7%. The larger digging forces generated the largest production in the 30 ton 33 U.S. ton class. *Arm Crowd Force: *Bucket Digging Force: 16800 kgf 37,040 lb. 20400 kgf 44,970 lb. *Measured with Power Max function, 3185 mm 10'5" and SAE rating Smooth Loading Operation Two return hoses improve hydraulic performance. In the arm out function, a portion of the oil is returned to the tank smoothly. Economy Mode Two return hoses Economy mode is environmentally friendly. Fuel consumption is reduced 20% (compared with PC300HD-7 Active mode) and production is equal to the PC300HD-6 heavy duty mode. Two Boom Settings Smooth mode provides easy operation for gathering blasted rock or scraping down operation. When maximum digging force is needed, switch to Power mode for more effective excavating. Smooth mode Power mode Working Mode Application Advantage A Active mode Maximum production/power Fast cycle times E Economy mode Excellent fuel economy L B Lifting mode Breaker operation Hydraulic pressure is increased by 7% Optimum engine rpm, hydraulic flow Boom floats upward, reducing lifting of machine front. This facilitates gathering blasted rock and scraping down operations. Boom pushing force is increased, ditch digging and box digging operation on hard ground are improved. 4
Multi-Function Color Monitor PC300HD-7 HYDRAULIC EXCAVATOR A newly developed Multi-Function Color Monitor has multiple functions, such as Working mode selection, hydraulic pump oil flow adjustment for matching to attachment, and maintenance interval notice, etc. Working Mode Selection The Multi-Function Color Monitor allows for easy selection of the working modes (A, E, L and B modes). EMMS (Equipment Management Monitoring System) Monitor Function Controller monitors engine oil level, coolant temperature, battery charge and air clogging, etc. If the controller finds any abnormality, it is displayed. Maintenance Function The monitor informs replacement time of oil, filters and other maintenance items when the designated interval is reached. Trouble Data Memory Function The monitor stores machine abnormalities for effective troubleshooting. Excellent Reliability and Durability High Rigidity Work Equipment The arm and boom are strengthened to correspond to increasing bucket and arm digging forces. The arm and boom cross sectional strength are also increased 35% and 9% respectively. The boom and arm have large cross-sectional dimensions as well as continuous groove welding, improving digging and sidecontact strength. Sturdy Frame Structure The revolving frame, center frame and undercarriage are designed by using the most advanced three-dimensional CAD and FEM analysis technology. Reliable Components All of the major machine components, such as engine, hydraulic pumps, hydraulic motors and control valves, etc., are exclusively designed and manufactured by Komatsu. Highly Reliable Electronic Devices Exclusively designed electronic devices have passed severe testing. Controller Sensors Connectors Heat resistant wiring 5
WORKING ENVIRONMENT PC300HD-7 cab interior is spacious and provides a comfortable working environment Large Comfortable Cab Comfortable Cab New PC300HD-7 s cab volume is increased by 14%, offering an exceptionally comfortable operating environment. The large cab enables full flat reclining of the seat back. Pressurized Cab The air conditioner, air filter and a higher internal air pressure (6.0 mm Aq 0.2" Aq) prevent external dust from entering the cab. Low Noise Design Noise level is remarkably reduced, not only engine noise but also noise when swinging and hydraulic relief. Photo may include optional equipment. Low Vibration with Cab Damper Mounting PC300HD-7 uses new, improved multi-layer viscous mount system that incorporates longer stroke and the addition of a spring. The new cab damper mounting combined with strengthened left and right side decks aids vibration reduction at operator seat. Vibration at floor is reduced from 120 db (VL) to 115 db (VL). db (VL) is index for expressing size of vibration. Silic Skylight Sliding Window Washable Cab Floormat The PC300HD-7 s cab floormat is easy to keep clean. The gently inclined surface has a flanged floormat and drainage holes to facilitate runoff.

MAINTENANCE FEATURES Easy Maintenance Komatsu designed the PC300HD-7 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 PC300HD-7. Reducing Maintenance Costs Hydraulic Oil and Filter/Engine Oil and Filter Replacement Interval Extended The new high performance filters are used in the hydraulic circuit and engine. Hydraulic oil filter, engine oil, and engine oil filter element replacement intervals are significantly extended to reduce maintenance costs. Easy Radiator Cleaning Easy Radiator Cleaning Clearance between radiator and oil cooler is increased to facilitate radiator core cleaning with an air nozzle. Comparison of Replacement Intervals unit: hours PC300HD-7 PC300HD-6 Engine oil 500 250 Engine oil filter 500 250 Hydraulic oil 5,000 5,000 Hydraulic oil filter 1,000 500 Water Separator is standard equipment, removing water mixed in fuel and preventing fuel system damage. Remote Mounted Engine Oil Filter Outer Air Filter Water Separator Easy Access to Engine Oil Filter and Fuel Drain Valve. Engine oil filter and fuel drain valve are remotely mounted to improve accessibility. Inner Air Filter Removal and installation of air conditioner filter element, without tools, facilitates cleaning. Easy Cab Filter Maintenance Tool free removal of the internal and external cab filters. All Work Equipment Lubrication Intervals are 500 Hours with Optional SCSH Bushings (Excluding Bucket) Newly developed SCSH bushings are used on bucket and arm top bushing; end faces are injected with Tungsten Carbide. All bushing lubrication intervals of work equipment are extended from 100 hours to 500 hours (excluding the bucket) reducing maintenance costs. SCSH (Steel Copper Sinter Hard Material) bushing is based on ferroalloy powder metallurgy (carbonized treatment). It contains a special lubricant in pores, and the hard particles are diffused to improve durability for wear and scratching. Special Lubricants Contained in Pores Hard Particles Diffused Tungsten Carbide Injected SCSH Bushing Cu (Copper) Tungsten Carbide Injected Bushing Tungsten Carbide is injected into the end faces of the arm top bushing to form a hard film, reducing wear of contacting surfaces and fluttering of the bucket. Fuel Tank Capacity Increased Fuel tank capacity is increased from 540 ltr 142.7 U.S. gal to 605 ltr 160 U.S. gal. to extend operating hours before refueling. The fuel tank is treated for rust prevention and improved corrosion resistance. 8
