4 MR-3 SERIES COMPACT H YDRAULIC E XCAVATOR PRODUCTIVITY FEATURES Tight Tail Swing Operator is able to focus on the work in front of them and worry less about a rear swing impact, even in confined areas with only an 80mm 3" projection over the tracks. CLSS HydrauMind Hydraulic System When two or more actuators are operated simultaneously, the pressure-compensated CLSS system ensures each actuator works according to its control input, regardless of the size of the load. This gives the operator precise control at all times. Confined Job Site Advantage Operator can focus on digging and improve productivity, because they can worry less about obstacles to the rear of the machine, such as parked cars, walls and trees. 2,070mm 6'9"* 2,250mm 7'5"* 2,515mm 8'3"* PCMR-3 2,415mm 7'11"* 2,550mm 8'4"* PC45MR-3 2,8mm 9'3"* PC55MR-3 2,800mm 9'2"* * : When boom swing Automatic Two-speed Travel The travel speed selector switch installed on the blade control allows the operator to engage high speed travel. Once engaged the system automatically senses he travel load and shifts between high speed and low speed travel. Expandable undercarriage () The can pass through narrow space due to narrow width and undercarriage can be expanded for good stability during excavation. expanded 80mm reduced 990mm 4

Fully Opening Engine Door and Cover Allow easy access for daily checks and regular maintenance. Photo may include optional equipment High Strength X-track Frame X-track frame is a large hydraulic excavator concept and deters dirt and debris build up saving the operator valuable time when cleaning the machine. Wide opening Larger Diameter Swing Pin Has high durability and maintains suitable clearances between pin and bushing after long-term operation. Round shape design DT Connector DT connectors are moisture and dust resistant. O-ring Face Seal O-ring face seals are highly reliable. 8

9 COMPACT HYDRAULIC EXCAVATOR MR-3 SERIES FEATURES Two-post ROPS & OPG Canopy ROPS [Roll-Over Protective Structures] This canopy meets the requirements of ROPS, with the advantage of a two-post design. Neutral Engine Start System Locks out drives and hydraulics during machine start up. Tie-Downs or Anchor Points Large tie-downs or anchor points in the track frame and blade allow the machine to be secured quickly for transport. OPTIONAL EQUIPMENT Roadliner (not available for and ) Replacement is fast, easy and cost efficient as individual shoes are replaced when damaged or worn instead of replacing the entire track. PA Blade (not available for, and ) Steel Shoes with Pad Optional Blade (Bolt-on cutting edge type) 9
