IMPORTANT ITEMS THAT SHOULD BE FOLLOWED BY THE OWNER OF A MASSEY-HARRIS SELF-PROPELLED COMBINE

'Vhere right and leftt are mentioned in this book it will be considered from a position behind machine looking forward. In other words, the grain tank or bagger attachment is on the left side of the machine.

1. Do not set the cylinder at extremely high speeds. 2. Do not work with sieves that are not the proper ones for the grain

being threshed. . 8. Do not use speeds which are not those indicated in the present ~

structiona. 4. Do not have filler plates in concave it you are cracking grain. o. Do not grind up the straw. 6. D9 not work without water in the radiator. 7. Always check to see that there is·the proper amount of oil in the motor. 8. Take care to oil all bearings properly. 9. Take care that you have the proper amount of oil in all gear eases ..

10. '"fike care that clean grain is not thrown over the end of the shaker "hue..

11. Do not permit elean grain to go into the return. 12. Do not cut excessive amounts of straw and overload the machine. 18. Do not demand too mueh from the machine. 14. Take care not to allow the machine to do poor work at any time without

making a careful examination and correcting whatever is wrong. 15. Do not make any adjustment on the machine with the motor running. 16. Do not work underneath the macp.ine with the motor running. 17. Keep hands away from all moving parts. 18. Take care to exa.m.ine and properly clean air cleaner daily 19. Do not engage the grain tank unloader clutch while the traction is in

motion. 20. Do not permit the carrier chain in elevator to cylinder to become slack. 21. Keep all tires inflated to the proper pressures. 22. The down draft chute and the radiator must be kept free of chaff.

WINTER STORAGE

In storing the machine for winter, the following points should be noted:

Put the machine on blocks to take the weight off the tires. Remove all belts and canvasses. Remove roller chains and store in oil. Drain water from the radiator. Lubricate all bearings throughout the machine.

ENGINE CARE DURING WINTER STORAGE

FUEL SYSTEM Drain the fuel tank completely; run the engine until it stops, thus

making sure that all fuel is exhausted from the system; clean the sediment straps at the fuel bowl and carburetor. Then disconnect and blowout the fuel lines.

ENGINE CONDITIONING It is recommended that the motor be rust-proofed before laying up

for a long period. F'or this purpose, use a good make of rust-proof oil similar to No.-Ox-Id, Grade DDX, manufactured by the Dearborn Chemical Company, or Rust-Ban 337 manufactured by the Imperial Oil Company. Use these oils according to maker's directions.

COOLING SYSTEM If freezing temperatures are to be encountered in unheated storage,

the cooling system should be either completely drained or protected by sufficient anti-freeze for the lowest temperature that will be experienced.

A "Full" cooling system is less subject to rust and corrosion than an empty one, but the availability of anti-freeze may of necessity deter­mine your procedure. If the anti-freeze solution remains in the stored machine, the condition of all hose connections should be carefully checked at the end of the storage period. If the cooling system is drained, DO­NOT FORGET TI-IE CYLINDER BLOCK DRAIN COCK LOCATED ON THE SIDE OF THE ENGINE.

CLUTCH Block or wire Traction Clutch Pedal down to the floor boards in a

completely released positIOn to avoid discs sticking to the fly-wheel or pressure plate. Also disengage clutch driving threshing mechanism.

PREPARING THE ENGINE FOR· SERVICE AFTER WINTER STORAGE.

COOLING SYSTEM Fin radiator with water (use soft water if you have it). See that core

and intake are clear of obstructions. Grease water pump (use water pump grease).

LUBRICATION See that oil level in engine is up to 3;4 mark on bayonet gauge. Oil all points of lubrication, such as Starter, Generator, Distributor, etc. The oil in the engine should be replaced with new oil, particularly if

rust proof oil has been used during storage.

AIR CLEANER Clean and refill with oil.

OIL FILTER Check oil filter; replace element, if necessary, as a further precaution

to assure satisfactory engine performance in your Combine; it is suggested that before the unit is placed in service, the engine be started and run for a period of 30 to 45 rninutes, after which the engine should receive the minor tune-up operations.

CARE AND OPERATION OF MO"roR

FUEL - Use 68-70 Octane Gasoline, manufactured by a reputable Company. OIL Quality -. Always use a good grade of oil, manufactured by a reputable company. For engine run-in - In new engines for the first 20 hour-run-in. period, use S.A.E. 10 oil. After engine run-in - 1:.188 S.A.E. 20 in spring and fall and S.A.E. 30 for summer operation. After the run-in period, change the oil every. 20 to 30 hours, and always keep the oil level up to the mark indicated 011 the dip­stick. Never use heavier oil than S.A.E. 30. Do not add oil until the level is belo-w the 34 mark on the dip-stick.

Oil should be changed at the finish of the working period .. either at mid-day or at night1• wh~'-!n the oil is hot. The hot oil is more fluid and win flush out the crank case better in this condition and leave it cleaner. OIL PRESSURE - Once the motor has been started and is running at normal speed the oil gauge should show pressure. The operator should look at the oil gauge frequently. If the oil pressure fails, it may be due to the fonowing causes:

on Level Low: Fill up the crank case to the proper level indicated ')n the bayonet gauge.

Dirt in the Oil Filter in the Bot tom of the Crank Case: Oil LiueB broken: on Connections Loose;;

ATrENTION It IS dangerous to clean out the crank case with gasoline or similar

fluids, because in this way the. motor can be damaged. Do not permit the motor to idle at excessivelJr slow speeds, because in this way it does not properly lubricate itself.

If motor is properly taken care of and our instructions followed, it will give long service without the necessity of any mechanical revision. GOVERNOR

'The governor on the motor of the No. 21 Self-propelled Combine is not lubricated by the oiling system of the motor, but is to be filled to the proper level by the operator. This is to be serviced once da.ily by the operatore

Particular attention must be given this lubrication before the motor iB started when the Combine is delivered and being set up.

The oil filler cap is Jocated on the top of the governor body and the oil level cap is located low on the end of the governor body. When filling the governor, hold the oil level cap open to permit air to escape as the oil runs in. UBe regular motor oil.

BE SURE SUFFICIENT OIL IS PUT IN THE GOVERNOR TO MAKE IT RUN OUT TI"iE OIL LEVEL CAP

RADIATOR If the radiator heats excessively (this can be checked by the heat

gauge on the dash) it is likely to be from one of the following causes: B01t drivjng Fan too slack. Radiator choked up with chaff. Lac k of water. Screen over radiator blocked up with chaff.

It is advisable to use in the radiator clean rain ·water if pos8ible. Be sure to keep water up to the proper Ievet .
