SECTION 4 OPERATING Page 8 INSTRUMENT PANEL 10. ENGINE OIL PRESSURE GAUGE This gauge shows the pressure at which the lubricating oil is circulating through the engine. The pointer must register in the green area during operation of the engine. 12. TRANSMISSION SYSTEM OIL TEMPERATURE GAUGE This gauge shows the temperature of oil in transmission system. The pointer of the gauge must be in the GREEN area of the gauge. If the pointer is above the GREEN area of the gauge check the following: if the transmission is not in a gear range too high for the load handled, oil level in the rear main frame, the radiator for cleanness, suction filter for cleanness and suction line for leaks.
If the pointer still remains beyond the GREEN area, consult an Authorized Distributor of Construction Equipment. 13. VOLTMETER The voltmeter indicates the condition of the batteries. At low idle speed, the gauge pointer should be within the green with white stripe area, which indicates a good battery charge. If the voltage drops below this area, the batteries should be checked. With the engine operating above low idle speed, the pointer should be within the upper green area, which is the normal operating range. If the pointer drops below or exceeds this area, the battery, alternator or wiring may be at fault. 14.
LOW ENGINE COOLANT AND LOW OIL PRESSURE ALARM This alarm will sound when engine lubricating oil pressure or coolant level in the radiator drops below normal. If so, stop the machine and find out which warning light glows and check the gauge indication. 15. HOURMETER The hourmeter electrically records actual hours of engine operation. The purpose of the hourmeter is to indicate when to perform the recommended maintenance and lubrication operations. The hourmeter will register only when the engine is running. 16. START AND WARNING LIGHTS CHECK BUTTON The button is used to crank the engine. IMPORTANT:
To prevent damage to the starter motor and avoid low battery output, do not continuously crank the engine for more then 30-second intervals. Allow 2 to 3 minute recovery period between cranking. Place the transmission neutral lock in neutral (OFF) and the electric system master switch to the ON position. Prior to starting the engine move the engine speed and shut down lever fully forward (OFF position), depress the starting switch and check if all warning lights glow. If any warning light doesn’t glow that indicates that the bulb is defective or its circuit is broken. 17. LIGHTS SWITCH The work light switches are the rocker type switches.
Activation of the switches turns on front and/or rear work lights. 18. ETHER INJECTOR SWITCH This switch controls the ether injector for cold weather starting. Refer to “STARTING THE ENGINE” for proper operation of this switch. TD-15H DRESSTA
