Page 5: Safety Precautions
SAFETY PRECAUTIONS Read carefully these instructions on safety and use before starting to operate the combine. Time spent in becom- ing familiar with the instructions now, will save you money or may even spare you from injury. Before accepting the delivery of the combine, make sure it conforms to the delivery contract. Do not t the combine with any accessories not approved of by the Manufacturer.
Page 6 Never use the combine for anything but threshing. Manual feeding of crops onto the cutting table is pro- hibited. Before starting, particularly reversing, make sure that everybody nearby is aware of your intentions. Test the brakes as soon as you start, and stop immedi- ately if the brakes or steering operate defectively.
Page 7 In Case of an Accident If there is an accident despite all precautions, keep calm and consider carefully what to do. First try to re- verse the combine away from the power line. If there are other people near, ask them to check that the com- bine is not stuck in the line.
Page 8 4. REPAIR AND SERVICE Always keep the combine in good condition. Check the condition of fast moving parts daily. Pay special attention to the transmission mechanism and the rotating chopper knives. Replace defective parts before they become dangerous. Clean, repair and service the combine with the trans- mission and engine off, the ignition key off the ignition switch and the master switch in its off position.
Page 9 caution shall be practised. 6. FIRE SAFETY Two factors are needed to start a re ammable material and ignition; oxygen is always available. Threshing generates a lot of light and highly ammable dust. Therefore it is important to clean the combine on a regular basis, and the engine compartment daily.

Page 75 Operation / adjustment There is no separate power switch in the equipment, but it gets switched on when the engine is started. Starting up takes a while. The basic factory settings can be adjusted to suit the conditions. The loss sensors have a three-position switch by which the basic setting is made. The symbol on the switch displays three different-size rings: a small one for hayseeds and rape, a medium size one for grain and a big one for peas and beans.
Page 76 Service Loss sensors require regular service. Their surfaces must be kept clean. In damp conditions dirt may accumulate on the sensor surfaces. Remove the dirt while still damp. Do not use a sharp tool, as the surface is a microphone cover.
Page 77: Dhc
Presetting of Cutting Height Always keep the equipment in good condition. Make sure you repair any defects as soon as they appear. Faulty equipment must not be used. Before starting the combine, make sure the DHC se- lection switch A is in its mid position. Make it a rule to Keep in mind that when the equipment is switched on, there is an automatic movement.
Page 78: Driving And Threshing Instructions
DRIVING AND THRESHING INSTRUCTIONS Before Starting the Combine Check that: There are no foreign objects inside the combine. The oil levels are correct engine, hydraulic tanks . There is coolant in the cooling system. There is fuel in the tank. The threshing mechanism and unloading pipe clutches are in neutral.
Page 79 When Driving on the Road: The brake pedals must be latched together. Brake smoothly as the rear wheels easily rise from the ground when applying the brakes violently. Never drive downhill with the gear in neutral. In accordance with the statutory traf c regulations when driving on the road, the cutting table guards shall be mounted, the front and rear lights correctly aligned, only the headlights on and the grain tank empty.
Page 80 Threshing Instructions Choose the Correct Time and Conditions Before starting the harvest, make sure that the crop to be threshed is ripe and dry enough. The germinating power of most crops is easily reduced if the threshing moisture exceeds 25%. Moreover, moist crops complicate harvesting and overload the threshing mechanism.
Page 81 For laid-down crops, set the reel forward, reel speed higher than the combine ground speed and the reel an- gled to facilitate the gathering of the crop, the knife cut- ting below the heads, g. M3. When using crop lifters, the reel should feed the cut crop onto the table auger with the reel tines in the normal position.
Page 82 Causes for table loss: The reel has threshed the grain onto the eld due to too high or low revolutions and too wide a clearance. Local blockage in the knife causes a depressed and uncut section in the eld. This may be due to a damaged knife plate or nger.
Page 83 If the sample is not clean, the reason could be: Insuf cient fan speed Incorrect direction of fans Grain sieve holes too large for crop Chaffer sieve set too wide open Forward speed too low insuf cient load on the threshing mechanism Crop sparse in places and weedy Cylinder-concave clearance too small Too many breaks in threshing turning, etc.

Page 116 DIFFERENTIAL LOCK (Fig. R5) The lock needs to be adjusted if it does not function per- fectly, or if, for some reason, it has been necessary to disassemble it. With the adjustment make sure the cylinder does not push the engagement fork too far and that the disen- gaged position of the lock is suf ciently far from the engaged position.
Page 117: Hydraulics
HYDRAULICS General Description Traction hydraulics and working hydraulics use a joint oil tank and lter. Both systems have their own pumps. Hydrostatic steering gets its oil from working hydraulics by means of a priority valve. The valve always supplies the amount of oil needed in steering and the rest can be used in other hydraulics.
Page 118 Used oil and lter are problem waste, which shall be disposed of in an appropriate manner. Use an oil type in accordance with the oil table. Make sure the oil is free from any impurities. Always use a clean funnel. After oil change let the engine idle for some 15 minutes during which time no hydraulics must be used.

Page 122 Sensors of ELECTRICAL SPEEDOMETERS The sensors of electrical speedometers (driving speed as well as fan and cylinder speeds) are located in the gearbox and at the ends of the respective shafts. To guarantee the correct functioning of the sensor, make sure that distance a between the sensor and the pulse disc (or the gear) is 1+ - 0.5 mm.
Page 123 BATTERY The gas generated by the battery is very explosive. Avoid open re and sparks in the vicinity of the battery. When servicing any electrical equipment, disconnect the negative cable of the battery. During the harvesting period the engine recharging equipment keeps the battery charged. At other times, check the state of the battery at regular intervals and recharge if necessary.
Page 124 If an auxiliary battery is needed for starting, proceed as follows: Check that the voltage of the auxiliary battery is 12 . Make sure the combine battery has not frozen; a at battery freezes in -10°C. Follow carefully the connecting sequence given below: With the auxiliary starting cables connect the positive poles of the batteries (marked with red paint, a P or a + symbol).
Page 125: Lubrication
LUBRICATION Do not lubricate while the engine is running. Remove the key and lock the parking brake before starting lubricat- ing. The cutting table and reel supports must be locked or lowered when lubricating. The table below gives recommended lubricants to be used in different temperatures. The table also gives different types of air conditioning liquids, although they do not normally have to be changed.

Page 138 Rear Weights The Standard Threshing Unit The need for rear weights depends on the combine type and what kinds of accessories and cutting table are used. The main principle is that 20% of the total weight rests on the rear axle. Use of extra weights is not recommended with cereal header Approximately 600 kg of additional weight is required on a combine with standard threshing mechanism (with the weight of the maize header 1400 kg).
Page 139 3 When Harvesting in Freezing Conditions Remember to clean the elevators and grain augers daily after threshing. If this is not done, they may be frozen the next morning, which will damage them. When modifying the combine back to cereal harvesting, special parts and components shall be replaced with the original ones intended for cereal harvesting.
