At the heart of the EX-200-5 LC lies a robust Isuzu A-6BG1T six-cylinder turbocharged diesel engine, delivering about 132 hp (98 kW) at 1,950 rpm and a solid 340 lb-ft (461 Nm) of torque at 1,600 rpm. This powerplant, known for its smooth throttle response and reliable performance, is carefully matched to Hitachi’s advanced hydraulic pump system .
Operators benefit from a sophisticated E-P (electronic-pilot) control system, combining micro-computer command with multiple actuators to enable responsive multi-function motion—particularly swing, lift, and bucket curl operations. A nifty power-boost feature grants a temporary 6 % hydraulic power increase when needed, ideal for demanding lifts or heavy digging bursts .
Thermal Management & Durability
This machine keeps its cool, literally. A spacious 23 L radiator coolant capacity, snug fan shroud, and high-capacity fan layout ensure efficient heat dispersion. Engine compartment ventilation—including side vents—promotes optimal thermal performance, a key to sustained productivity .
A steel bulkhead separates the engine from hydraulic pumps, keeping both compartments cleaner, quieter, and easier to maintain.
Operator Comfort & Cabin Design
Inside, the EX-200-5 LC treats operators to one of the most comfortable cabs in its class. Broad and spacious—with a width of 1,005 mm (3 ft 4 in)—it provides ample legroom, an expansive right-side window, and a lowered front cross-piece for excellent visibility .
The cab rests on six fluid-filled elastic mounts, effectively isolating vibrations. Seat ergonomics are top-notch: adjustable armrests, seat slide functionality, tilt, raise/lower, and a tilting headrest. Climate control includes powerful air conditioning, a hot-and-cool box, and dual rotatable louvers, all controlled with automotive-style simplicity .
Dimensions, Reach & Stability
Depending on boom and stick configurations, users can expect varied operational geometry. One setup offers:
Other key specs include:
Here are some common issues with practical checks and fixes:
Take, for example, a contractor in Ohio who inherited a 2000 EX-200-5 LC from a retired foreman. The knob was stuck in “rabbit” mode, and no matter what, it stayed fast. After a quick continuity test confirmed a worn potentiometer, a new switch brought speed control back to smooth normalcy—and saved the project from costly downtime.

Dimensions, Reach & Stability
Depending on boom and stick configurations, users can expect varied operational geometry. One setup offers:
- Maximum cutting height: ~30 ft
- Maximum digging depth: ~20 ft
- Loading height: ~21 ft
- Ground reach: ~30 ft
- Vertical digging depth: ~17 ft
- Shipping dimensions: ~10 ft tall × 32 ft long
Other key specs include:
- Operating weight: ~44,100 lb (20 ton)
- Fuel capacity: ~82 gal
- Hydraulic fluid: ~53 gal
- Engine oil: ~7 gal
- Swing gear oil: ~2 gal
- Travel speed: ~4 mph (6 kph)
- Ground pressure: ~4.6 psi
- Track length: ~12 ft
- Shoes per side: 49
- Track rollers per side: 8
Here are some common issues with practical checks and fixes:
- Travel-speed selector stuck on high: Often caused by a faulty potentiometer or worn internal contacts. Inspect the knob and wiring harness; test continuity with a multimeter. Cleaning or replacing the switch usually resolves the problem .
- Engine stalls when hydraulics fully engaged: A frequent culprit is a malfunctioning angle or load sensor. One effective technique: measure sensor voltage while operating; if machine runs well at a specific voltage (~1.45–1.54 V) and falters when it shifts, the sensor or its alignment may be at fault .
- Idle irregularities or sluggish hydraulics: These issues may stem from clogged fuel filters, a compromised idle control valve, or hydraulic drag. Regular inspections and replacements of fuel/air filters, and diagnosing hydraulic pressure drop, can help restore stable performance .

Technical Glossary
- E-P Control System: Electronic-pilot hydraulic system for precise motion control
- Bulkhead: Partition isolating engine compartment from hydraulic pumps
- Ground Pressure: Weight over surface area (low value indicates soft-ground capability)
- Potentiometer: Variable resistor used in knobs to control electrical signals
- Hydraulic Drag: Resistance in hydraulic systems causing sluggish motion
- Boom/Stick Configuration: Different lengths of boom (arm) and stick (dip) for reach or depth versatility
To keep your EX-200-5 LC running reliably:
- Establish a routine inspection schedule for fuel and hydraulic filters, idle valve, sensors, and selectors.
- Lubricate sensor connectors, and use dielectric grease if exposed to wet environments.
- Keep cooling fins and radiator spotless for optimum efficiency.
- Offer operators quick reference guides on symptoms like “jerky hydraulics” vs. “stalling”; empower them to flag early issues.
- When buying used, inquire about sensor maintenance and knob replacements—many older units show signs of wear here.
