6 CONTROLS
6.2.11 COMBINATION GAUGE____________________________________________________
The combination gauge shows the hours of operation, the level of
fuel and has six indicator lights to indicate the mower conditions.
The hour meter in the center of the gauge shows the hours of
operation of the mower. When the ignition switch is in the RUN
position, the hour meter is active.
The fuel gauge is above the hour meter in the center of the
gauge. The fuel gauge shows the level of fuel in the tank. Do not
allow the tank to become empty while you operate the mower.
The combination gauge indicator lights supply the following information:
The Red coolant-temperature light indicates that coolant temperature is more than 230° F (110° C). Stop unit
immediately. Remove the tree leaves, grass clippings and other objects that can decrease air flow through the
radiator screen, oil cooler and the radiator. If the engine continues to run hot, return mower to the service area.
The engine coolant is under pressure. To prevent injury, do not remove the radiator cap on a hot radiator.
The red hydraulic filter light indicates that the hydraulic filter must be replaced. Return the mower to the service
area and replace the filter.
The red hydraulic-level light indicates a low-fluid level in the hydraulic tank. Stop the mower immediately.
Visually inspect the mower for indications of leaks around connections, hoses and hydraulic components.
Return the mower to the service area for maintenance.
The hydraulic fluid is under pressure. To prevent injury, do not use your hands to find hydraulic leaks, use
paper or cardboard. Allow the hydraulic fluid to become cool before you check the fluid level or you add fluid
to the hydraulic tank.
The red engine oil-pressure light indicates engine oil pressure is less than 7 psi (0.48 BAR). Immediately
stop the engine and inspect oil level in the engine. If the oil-pressure light stays illuminated with the oil at
the correct level, stop the engine and tow the mower to the service area. NEVER operate the engine with
the oil-pressure light illuminated or Engine damage can occur.
