How to Use the Starter Switch

[NOTICE]

◆ Do not leave the starter key in the “ON” position with the engine stopped. The battery will run down if the working lamps, fan, or other equipment is used for hours with the engine off and the starter switch turned to BATT or ON. If using electrical equipment for long periods of time, be sure to run the engine to maintain the battery charge.

"START" ・・・Starts the engine. Release the key after the engine has started. The switch will automatically return to ON.

"BATT" ・・・・The fan, washer, wiper, horn, and working lamps can be used with the engine off.

"HEAT" ・・・・Energizes the engine preheating circuit. Use this position to start the engine in cold weather. Releasing the key automatically returns the switch to BATT.

Pre-starting Checks

Before starting the engine, perform the following inspection and checks:

1. Perform the pre-operational inspections.

◆ For an explanation of the engine pre-operational inspection procedure, see the "Engine Operation and Maintenance Manual".

2. Make sure that the controls are placed in the following positions:

Hoist, boom telescoping, boom elevating and swing control levers

"OFF" ・・・・・Shuts off the engine. The key can be inserted or removed in this position. Turning the switch back to OFF shuts off the engine.

"ON" ・・・・・・All electrical systems are activated.

Starting the Engine [NOTICE]

◆ Do not hold the starter switch in the start position for more than 15 seconds, as this will overheat the starter motor. If the first attempt to start the engine fails, wait at least 30 seconds before trying again.

Starting the Engine

1. Depress the brake pedal and position the starter switch at “START”.Release the key immediately once the engine has started.

◆ In cold weather, turn the starter switch to HEAT and hold it for about 10 seconds to preheat the engine. Once the engine has been preheated, immediately turn the starter switch to START.

◆ Do not step on the accelerator pedal if the PTO switch is on.

2. After warming up, turn the fuel control knob toward "L" to run the engine at idling speed (600 to 650 rpm).

Warm-up Checks

During warm-up, check for abnormal exhaust gas color, sound and vibration. Also, check that the gauges and indicator lamps related to the engine display their normal reading as shown. If not, shut off the engine and have the nearest TADANO distributor or dealer check the problem.

◆ When air pressure is low after draining water from the air tank or for other reasons, an alarm buzzer sounds to indicate low air pressure after the engine has started. The alarm buzzer will stop once a sufficient amount of air is supplied.
