This manual gives you the complete operating picture for the Yanmar AW70V, AW82V, and VNQ. It begins with the safety instructions you need before you turn the key, then walks through the control layout and the function of every lever, switch, and pedal. From there it covers field preparation, harvesting techniques for lodged and standing crops, and how to handle wet field conditions. The maintenance section is detailed, with oil and water capacities, replacement intervals for filters and fluids, and step-by-step adjustment procedures for cutter blades, chains, belts, and the crawler. The troubleshooting chapter breaks down engine, harvesting, conveying, and threshing problems by symptom and remedy. The technical specification chapter lists the AW70V’s dimensions, engine output, traveling speeds, and threshing capacities so you can confirm you are operating within the machine’s designed limits.

Why This Manual Matters

The Yanmar AW70V AW82V VNQ combine harvester is a substantial machine with a 4TNV98 engine, a 490-capacity grain tank, and an axial-flow threshing system. Running it without the correct operating procedures puts both the operator and the machine at risk. This manual is the reference for correct startup, safe harvesting, and proper shutdown. It also gives you the maintenance schedule that keeps the machine reliable through the harvest season. The adjustment procedures for the cutter blades, reel position, and platform auger are especially important if you want to minimize grain loss and avoid blockages. The troubleshooting tables help you diagnose problems quickly instead of guessing. And the technical specifications let you confirm that your operating conditions, crop types, and field angles are within the machine’s design limits.

What You Can Do With This Manual

• Perform daily pre-operation checks on the engine, fuel system, cooling system, and crawler
• Start and stop the engine safely, including cold-weather starting procedures
• Operate the combine in the field, including turning, traveling, and loading/unloading on a truck
• Harvest different crop conditions, including lodged crops and ridged fields
• Adjust the reel, cutter blades, platform auger, and chaff sieve for optimal harvesting performance
• Carry out the full maintenance schedule: engine oil, transmission oil, hydraulic oil, cooling water, fuel filter, air filter, and battery
• Adjust chains, belts, and the crawler to keep the machine running smoothly
• Troubleshoot engine, harvesting, conveying, and threshing problems using the symptom-based tables
• Look up the AW70V’s technical specifications, capacities, and operating limits
• Store the machine properly for long periods

Coverage for the AW70V, AW82V, and VNQ

The manual identifies the machine as the YANMAR combine harvester AW70V and includes a machine identification plate for the AW70V with the 4TNV98 engine. The filename and title also reference the AW82V and VNQ models. The operating procedures, safety instructions, maintenance intervals, and technical specifications in this manual apply to these Yanmar combine harvesters. The manual notes that it is for sales and use within the Philippines only and that export to other countries is prohibited.

Safety First

The manual opens with a detailed safety chapter that covers operator physical condition and clothing, fire prevention, fuel handling, pre-operation checks, and safe operation in the field. It uses DANGER, WARNING, and CAUTION callouts to flag hazards that could cause death, serious injury, or machine damage. Specific safety topics include refueling precautions, exhaust emission hazards, brake and control lever checks, rollover risks on slopes, power line clearance, and safe loading/unloading procedures. The safety labels chapter shows the attachment positions for all warning decals on the machine. If you are new to the AW70V or to combine harvesters in general, this section is essential reading before you start the engine.

Maintenance and Adjustment Procedures

The maintenance section of the Yanmar AW70V AW82V VNQ operator manual is extensive. It starts with the refueling, oiling, and water supply schedule, listing capacities and types for fuel, cooling water, engine oil, transmission oil, rotor drive case oil, and hydraulic oil. It then provides step-by-step procedures for checking and replacing engine oil, the engine oil filter, transmission oil, HST filter, hydraulic oil, cooling water, fuel filter, water separator, and air filter. You also get procedures for draining the fuel tank, bleeding the fuel system, cleaning the engine dust protector, and maintaining the battery. The adjustment chapter covers the cutter blades, the gap between the feeding auger and base plate, the gap between the platform auger finger and base plate, the position of the reel, fuse replacement, chain adjustment, belt adjustment, and crawler tension. These are the procedures that keep the machine cutting cleanly and threshing efficiently.

Troubleshooting the AW70V

The troubleshooting chapter is organized into three sections: engine, harvesting and conveying, and threshing and screening. Each section lists symptoms, what to check, and the remedy. Engine problems include the starter motor not working, the engine not starting even when the starter motor rotates, and the engine stopping unexpectedly during operation. Harvesting and conveying problems include crops not being conveyed, rice root being pulled out, heavy loss in the reaping section, and the reel getting stuck. Threshing and screening problems include incomplete threshing, grain splashing, abnormal noise in the threshing section, poor screening, and damaged grains. This chapter helps you diagnose and fix common problems without waiting for a dealer visit.
