Safety Hints

The opening chapter lays out the safety rules for before operating the machine, during operation, during maintenance, and parking. It covers protective clothing requirements, working near electrical lines with minimum safe separation distances for voltages from 6.6 kV to 275 kV, operating on slopes and soft ground, fire prevention and fire extinguisher use, battery and battery cable hazards, high-pressure line and hose safety, and the European Union vibration directive data for earthmoving machines. Warning labels on the machine are described with their locations and the hazards they address.

Specifications

This chapter provides the technical data for every R220LC-9S variant. It covers major components with a labelled diagram, dimensions and operating weights, bucket capacities, travel and swing speeds, gradeability, ground pressure, and maximum traction force. Working range charts give maximum digging reach, digging depth, digging height, and dumping height for the different boom and arm combinations. Lifting capacity tables show rated loads at various radii and load point heights for the standard, Long Reach, High Walker, and Amphibious configurations. Bucket selection guidance covers general purpose, heavy duty, rock-heavy duty, and slope finishing buckets with recommended applications. The undercarriage section details track shoe options, ground pressure for each shoe width, and roller and shoe quantities. Specifications for major components cover the engine, main pump, gear pump, main control valve, swing motor, travel motor, remote control valve, cylinders, shoes, and buckets. The chapter closes with recommended oils and lubricants for all service points across the ambient temperature range.

Operation

The operation chapter starts with suggestions for running a new machine through its first 100 hours, followed by pre-start checks. Engine starting and stopping procedures cover normal temperature and cold weather conditions, including the preheat and fuel warmer systems. The mode selection system explains power modes (P, S, E), work modes (general, breaker, crusher), user mode settings for engine speed, power shift, and idle speed, travel modes, and auto idle. Working device operation covers the left control lever for arm and swing, and the right control lever for boom and bucket. Traveling instructions include basic travel, travel on slopes, travel on soft ground, and towing the machine. Efficient working methods cover digging technique, truck loading, swing operation, and ditch digging. Operation in special work sites covers cold weather, sandy or dusty conditions, sea shore operation, mud and water, and rocky sites. The chapter also explains normal excavator phenomena such as arm roll-in speed variation, boom lowering sound, relief valve noise, and swing motor brake noise. Attachment lowering procedures with the accumulator are described, along with machine storage for periods over one month. RCV lever operating patterns are shown for ISO, A, B, and C types, with pattern change valve installation instructions. Switching the hydraulic attachment circuit between one-way flow for breakers and two-way flow for clamshells or shears is covered.

Transportation

The transportation chapter covers preparation for moving the machine, including route checks and trailer selection. Dimension and weight data are given for the base machine, boom assembly, arm assembly, bucket assembly, boom cylinder, cab assembly, and counterweight for the standard, Long Reach, and High Walker models. Loading the machine onto a trailer is described with safety lever positioning, swing procedures, and stay bracket fixing. Fixing the machine covers switch positions, lock security, and chain tie-down. Loading and unloading by crane covers wire rope and stay installation with proper hookup points.

Maintenance

The maintenance chapter is the largest section, covering maintenance intervals, proper maintenance practices, relieving hydraulic system pressure, precautions when installing hydraulic hoses and pipes, and periodical replacement of safety parts. Tightening torque tables cover coarse and fine thread bolts, pipe and hose fittings for flare and ORFS types, and major component torque values for engine, hydraulic system, power train, undercarriage, and other mountings. Fuel, coolant, and lubricant specifications are given along with a recommended oils chart by ambient temperature. The maintenance check list covers daily service before starting, every 50 hours, initial 50 hours, every 200 hours, initial 250 hours, every 250 hours, every 500 hours, every 1000 hours, every 2000 hours, every 5000 hours, and when required services.

What This Manual Does For You

If you run or service an R220LC-9S, this manual puts the machine’s own reference data in your hands. You can set the correct engine speed and power shift values for the job, adjust the boom and arm speeds to suit the operator, set up breaker or crusher mode with the right flow, and understand what each warning lamp is telling you before a small issue becomes a major repair. The maintenance schedules tell you what to check daily, what to change at each interval, and the exact lubricants and capacities to use. When something does go wrong, the troubleshooting guide gives you a structured way to identify the cause instead of guessing.

The value of having the correct procedures and specifications is hard to overstate on a machine that weighs over 21 tonnes and works with hydraulic pressures up to 350 kgf/cm2. Torque values matter. Oil types and capacities matter. Track tension matters. The R220LC-9S operation and maintenance manual gives you those values in one document instead of scattered notes and second-hand advice. The lifting capacity tables let you plan safe lifts. The working range charts let you set up the machine for the dig. The electrical and hydraulic system explanations help you trace faults logically.
