Walker MT Operating Instructions, Hourmeter, Voltmeter, Oil Pressure Warning Light, Warning Horn

Operating Instructions

Hourmeter

The hourmeter displays operating time accumu- lated while the ignition switch is in the ON position.

Voltmeter

The voltmeter displays battery and charging system voltage. An indication of low or high voltage (below

11.5volts or above 15.5 volts) indicates an electri- cal system failure. The cause of the failure should be determined and corrected.

Oil Pressure Warning Light

The oil pressure warning light indicates that engine oil pressure is below the safe operating range [below 3 to 5 PSI (21 to 34 kPa)]. This light (and warning horn) will come on when the ignition is turned ON, but should go off after the engine is started. If the light fails to come on when the ignition switch is turned ON, it could indicate a burned out bulb. If the light comes on during engine operation, stop the engine imme- diately and correct the source of the problem before further engine operation.

IMPORTANT: Continued operation of the engine with an illuminated oil pressure warning light MAY cause severe engine damage (if a low oil pressure condition exists).

Over Temperature Warning Light

The over temperature warning light indicates that engine oil temperature and/or cylinder head temper- ature are above the safe operating limit and the en- gine is overheating [above 305° F (152° C) oil or 450° F (232° C) cylinder head]. If this light comes on, there may be a problem with:

∙Engine cooling system (material packed into cyl- inder head cooling fins, clogged air intake screen)

∙Low oil level in crankcase

Stop the engine and correct the source of the prob- lem before further operation.

IMPORTANT: Continued operation of the engine with an illuminated over temperature warning light MAY cause severe engine damage (if a high oil tem- perature or head temperature condition exists).

Ignition Switch

The ignition switch is used to start and stop the en- gine. The switch has three positions: “O” is the OFF position, RUN is the position the key returns to after starting, and “S” is the START position. When start- ing the engine, turn the key clockwise to the “S” po- sition. Do not hold the key in the “S” position longer than 10 seconds. If the engine does not start, return the key to the “O” position for at least 60 seconds be- fore making a restart attempt. Prolonged cranking can damage the starter motor and shorten battery life. Release the key when the engine starts, and it will return to the “RUN” position. To stop the engine, rotate the key counterclockwise to the “O” position.

Warning Horn

The warning horn sounds to alert the operator that an unsafe engine condition is being indicated - when engine temperature is too high or engine oil pressure is too low. If the horn sounds, check the indicator lights and correct the problem before fur- ther operation.
