Purpose of the manual and how to use it safely. Intended use of the machine: dozing, smoothing, cutting into hard or frozen ground, ditching, felling trees, removing stumps. General view and directions of the machine (front, rear, left, right). Work possible using the bulldozer is described in the Operation section.
Positions of safety pictograms and labels on the machine. The manual lists each label (e.g. caution before operating or maintaining, caution when moving in reverse, leaving operator's seat, high-temperature coolant and oil, accumulator, track tension adjustment, battery, engine running, jump start prohibited, ROPS/FOPS). Labels must be kept clean and in place; damaged or missing labels must be replaced.
Display warning tag during inspection and maintenance. Keep workplace clean; select a suitable place; only authorized personnel; appoint a leader when working with others. Stop the engine before inspection and maintenance; lower work equipment, release hydraulic pressure, set parking brake and work equipment lock, block the tracks. When maintenance with engine running is necessary, two workers. Installing, removing, or storing attachments. Working at height and under the machine. Proper tools. Welding, battery, hammer, high-temperature coolant and oil, high-pressure oil and fuel, high-pressure hoses, noise, track tension adjustment (high-pressure grease), recoil spring, accumulator and gas spring, compressed air.
Door open lock, sash glass and intermediate lock, door pocket, ashtray, shovel holder. Car radio: power, volume, tone, display, preset stations, FM/AM. Air conditioner: handling and switches (cooling, dehumidifying, heating). Gauges and monitors: power train oil temperature, hydraulic oil temperature, user menu (clock adjustment, 12/24 h, daylight saving). Horn, room lamp, wiper switches. Explanation of components for daily use.
Adjustment of seat, mirrors, steering. Checks: fuel, coolant, engine oil, power train oil, hydraulic oil, air cleaner, electrical wiring, handrails and steps, gauges and monitor, seat belt, work equipment lock lever, blade and ripper control levers. Check that lamps light up (headlamps, rear lamps).
Normal starting procedure. Operations and checks after starting (warm-up, monitor readings).
Normal stopping. Parking the machine safely.
Shifting gears and shifting between forward and reverse. Steering the machine. Precautions for operation.
Work possible using the bulldozer (dozing, smoothing, cutting, etc.). Recommended mode for each type of operation. Adjusting posture of work equipment (blade and ripper). Raising blade and ripper, fuel control dial, decelerator pedal, proper sequence for work.
Parking the machine. Tips for longer undercarriage life. Check after finishing work: before stopping (coolant temperature, oil pressure, fuel level); after stopping — walk-around (work equipment, exterior, undercarriage, leaks), fill fuel tank, clean engine compartment, lock the machine.
Transportation means. Precautions when removing work equipment. Loading and unloading. Lifting the machine. Traveling on roads. Cold weather operation: precautions for low temperature, after completion of work, after cold weather. Long-term storage: before storage, during storage, after storage; starting the machine after long-term storage. Troubleshooting: after running out of fuel (bleeding air in fuel system, electric priming pump, restart procedure); starting engine when machine has failed (work equipment lock, control levers, battery clips, etc.).
Wear parts list. Recommended fuel, coolant, and lubricant. Use of fuel, coolant and lubricants according to ambient temperature. Recommended brands and quality for products other than Komatsu genuine oil.
