4.1.10 Reserve Fuel Valve: Located right of center on front of console. The reserve fuel

FUEL FLOW

RESERVE FUEL
Return the valve the "Right Tank ON" position after refueling the right tank.
Note: For 27 HP Daihatsu Diesel units, the operator must prime the fuel system
when the fuel tanks have gone empty. The primer pump is the gold button located
under the seat next to the console in the front left-hand corner. To prime the
system, push down on the primer pump until the tension becomes firm
(approximately 10-15 pushes).
4.1.11 Drive Wheel Release Valves: Located on the top right front corner of hydrostatic
pumps. Drive wheel release valves are used to release the hydrostatic drive
system to allow the machine to be pushed without the engine running. Tilt seat
up to gain access to pumps.
With a 5/8 wrench, turn both valves one turn counter-clockwise to release drive system.
Turn clockwise to reset system. DO NOT overtighten. DO NOT tow machine.
4.1.11 Coolant Temperature Gauge: Located at the front of the right fuel tank. The
coolant temperature gauge monitors the temperature of the engine coolant. The
engine will overheat if the coolant temperature becomes too high.
4.1.12 Voltmeter: Located next to the Coolant Temperature Gauge at the front of the
right fuel tank. The voltmeter measures the voltage output of the alternator.
Both high and low voltages will potentially damage the battery.
4.1.13 Water in Fuel Light (27 HP Daihatsu Diesel Only): Located on the console to the
right of the hour meter. An illuminated water in fuel light signals water in the
diesel fuel. Water should be drained from the fuel filter if the light is on.
IMPORTANT: Water or other contaminants in fuel can severely damage fuel
pump and/or other engine components.
4.1.14 Glow Plug Light (27 HP Daihatsu Diesel Only): Located on the console to the
right of the ignition switch. The glow plug light comes on when the ignition switch
is turned to the ON position. The glow plug light indicates the glow plugs are
preheating the combustion chamber. Wait for the glow plug light to go out before
starting the engine.
4.1.15 Warning Buzzer: Located behind the seat on the left hand side of the engine air
deflector. The buzzer is a warning signal for the following circumstances:
a) When the engine is not running and the ignition switch is turned to the ON
position, the buzzer emits intermittent beeps. The intermittent beeps remind
the user that the switch is ON and the hourmeter is running. A switch left ON
could also drain the battery.
b) When the engine is running and the buzzer emits a continuous beep, the
buzzer is warning the user that the engine is overheating. Perform the
following steps.
