(9, Fig. 3) to indicate when the transmission is in
torque converter drive.
Transmission Oil Pressure Switch (8) - Located in a
tee at the front of the transmission, sends a signal to
illuminate transmission oil pressure warning light (8 &
18, Fig. 3) to indicate when the transmission oil
pressure is low.
Transmission Oil Temperature Sender (7, Fig. 1) &
Transmission Oil Temperature Sender/Switch
(7, Fig. 2) -
The temperature switch (only on scraper)
sends a signal to illuminate transmission oil
temperature warning light (17, Fig. 3) when the scraper
transmission oil temperature rises above the safe
operating temperature.
The temperature senders sends a signal to the
Transmission Oil Temperature Gauge (2 & 4, Fig. 2) to
indicate converter-out oil temperature. The gauge
should read in the green zone during normal operation.
Watch for wide deviations from normal readings on the

Engine Coolant Level Senders (9) -
Located in the
radiator top tank, the sender sends a signal to engine
stop light (6 or 20, Fig. 3) indicating that the engine
coolant level is low.
Tachometer/Hourmeter (1, Fig. 3) - Driven from the
alternator, the tachometer indicates the number of
engine crankshaft revolutions per minute (rev/min).
Never accelerate the engine to speeds indicated by the
red zone on the dial face. A digital hourmeter is
incorporated in the tachometer to record total hours of
engine operation.
Transmission
The FUNK DF 158 transmission management system
monitors the transmissions at all times and sends a
signal to the display unit on the dash panel to alert the
operator of a fault in the transmission circuit.
Converter Drive Pressure Switch (13) - Located on
the top rear of the transmission, sends a signal to
illuminate transmission converter indicator light
