DRIVING THE TRACTOR

NOTE: The cab electrical system is not on until Rear View Mirror the key switch is on.

OPERATING THE CAB CONTROLS

Air Conditioner Switch and Control

This control has an "Off" and "Max." position for temperature control of the discharged air.

To help lower humidity, the air conditioner may be operated in conjunction with the heater.

The pressurizer fan switch must be turned on for the air conditioner system to operate.

Be sure to keep your doors closed when air conditioner is in operation.

Operate the air conditioner a few minutes periodi­cally during the off season to lubricate the seals.

If the evaporator freezes up it may become necessary to turn the control to a warmer setting.

Pressurizer Fan and Speed Switch

This control turns the pressurizer fan on and regulates air into cab.

Low, Medium,and High speeds are available.

This switch must be turned on to deliver heated or cooled air into the cab through adjustable louvers.

Windshield Wiper Switch

The windshield wiper is controlled by an "On" and "Off" switch.

Heater Temperature Control

This switch has an "Off" and "Max." position. In the "Max." position engine coolant flows through the heater core. The pressurizer fan switch and control must be turned on to deliver heated air.

7

This mirror enables the operator to view conditions at the rear of the tractor.

Dome Light

The dome light is on a live circuit and can be operated independent of tractor key switch. It is turned "On" and "Off" by a pushbutton switch adjacent to the light.

PREPARING THE TRACTOR FOR EACH DAY'S WORK

Check the level of the coolant in the recovery reservoir. Refer to "Cooling System".

Check the oil level in the engine crankcase. Also lubricate the chassis points recommended for daily service. Refer to "Lubrication Guide" and "Lubri­cation Table".

Inspect the tires for general condition.

FUEL GAUGE

in When the key switch is turned on, the fuel gauge indicates the level of the fuel in the fuel tank.

NOTE: The key must be left in the "On" position while the engine is running so the fuel gauge will function.

FILLING THE FUEL TANK

A CAUTION! Never remove the fuel tank cap or fill the fuel tank when near an open flame. Do not smoke when work-

ing around inflammable fuel as the air around the tractor is mixed with highly explosive vapor. When pouring fuel, keep the container or hose nozzle in contact with the metal of the fuel tank to avoid the possibility of an electric spark igniting the fuel.

DRIVING THE TRACTOR

Range Selector Shift Pattern MA-l0726

Range and speed shift pattern.

Five forward speeds and one reverse speed are available in each range. The speed lever also has a neutral position.

To shift, depress the clutch pedal and select the desired gear.

CLUTCH PEDAL

Depress the clutch pedal when stopping tractor or shifting gears. Depress clutch pedal completely to actuate clutch brake before attempting gear engagement to prevent possible transmission damage.

For increased clutch life, release clutch pedal slowly to start tractor motion, at an engine speed not over 1,700 r.p.m. After tractor is in motion, engine r.p.m. should be increased to rated speed.

TRANSMISSION BRAKE OPERATION

To operate the transmission brake, depress the clutch pedal completely. The operator will feel the transmission brake because pedal effort will in­crease from approximately 55 to 80 pounds. This will stop the transmission gears from turning and allow you to shift the transmission into gear.

If the transmission brake does not work properly this is an indication that your clutch may need adjustment and the proper action should be taken.

10

STARTING THE TRACTOR

Start the engine. Then advance the engine speed control lever (refer to "Engine and Fuel System").

Disengage the park brake. To prevent transmission damage, depress clutch completely to actuate transmission brake before attempting gear en­gagement.

With the clutch in the disengaged position, move the transmission range lever to the desired range, "HI" (high) or "LO" (low). Then move the speed control lever to the desired speed.

Start the tractor in motion by slowly releasing the clutch pedal and advancing the engine speed con­trol lever to a position where the engine operates best for the load to be handled.

NOTE: Do not shift gears while the engine clutch is engaged or while the tractor is in motion.

Do not "ride" the clutch or brake pedals by resting the feet on the pedals while driving the tractor because this will result in excessive wear on the linings.

TACHOMETER

~ This meter indicates engine r.p.m. B It also records engine hours of operation.

SPEEDOMETER

~ This instrument shows normal tractor iii speeds in miles per hour.

DIFFERENTIAL OIL LEVEL TELLITE

This tellite is used as a warning and will come on when the level of lubricant in the front drive unit is low. The light will go out when the lubricant js at proper level.
