OM3005.3 7/96 Operation - Section 3 Instrument Panel and Controls Page 3-15 INSTRUMENTS AND CONTROLS INSTRUMENT PANEL (FIGURE 3-5) (5) Windshield Wiper The operator must understand the function and opera- tion of each instrument and control. This knowledge is essential for proper and safe operation of the machine. Items that are marked (OPTIONAL) may not apply to this truck. The windshield wiper control switch is a three position rocker switch. Moving the switch from "Off" to the second position places the wiper in the low or slow cycle. Pushing the switch to the third po- sition places the wiper motor in high or fast cycle.
(1) Fog Lights (Optional) The fog lights are an optional piece of equipment, useful in heavy rain and foggy conditions. When pre- sent, the switch has two positions, "On" and "Off". (6) Engine Starting Aid The ether starting aid is used for cold weather starting and is con- trolled by a switch, spring-loaded to the "Off" position. When the switch is held in the "On" position, the ether is injected into the engine intake manifold to aid in cold weather starting. In cold weather, below 50 o F (10 o C), turn the keyswitch (7) to the "Start" position. Push the cold weather starting switch to the "On" position for three seconds while cranking , then release.
If engine does not start, wait thirty seconds before repeating the procedure. (2) Lights- All The instrument panel lights and the head lights are controlled by a three position switch. Moving the switch from the "Off" position to the second position completes the cir- cuit from battery to the instrument panel lights and taillights. Moving the switch to the third position completes the circuit to the head lights in addition to the panel and tail lights. (7) Keyswitch The key switch is a three position ("Off", "Run", "Start") switch. When it is moved to the "Run" position, the switch activates the accessory circuits.
When moved to the "Start" position, the engine’s starting system is activated. After engine start, allow the switch to return to the spring-loaded "Run" position. (3) Lights - Instrument Panel The panel light dimmer control is a rheostat which allows the operator to vary the brightness of the instru- ment panel lights. (8) Engine Shut Down (Not Used) (4) Windshield Washer This position is not used on the 210M equipped with the Cummins Quantum QSK-19 engine. The windshield washer switch, when held in the "On" position, di- rects water from the reservoir (lo- cated in the cab to the left of the passenger seatbox) to the wind- shield for cleaning purposes.
Wip- ers (5) should be operating when washer is activated. This switch is spring loaded to the "Off" position. The windshield washer has a 2 qt. (2 l) plastic container. (9) Windshield Wiper Fuse Holder This is a 15 amp.- dual element, time delay (slow blow) type fuse. Replacement with any other type is not recommended.
