Throttle Control; Blade Switch; Fuel Shut Off Valve; Service Meter - RedMax RZT48 Operator's Manual

CONTROLS

Throttle Control

The throttle control regulates the engine speed
and the rate of rotation of the blades, assuming
the blade switch is pulled out.
To increase or decrease the engine speed, the
control is moved forward or back respectively.
Avoid idling the engine for long periods, as there
is a risk of fouling the spark plugs. USE FULL
THROTTLE WHEN MOWING, for best mower
performance and battery charging.

Blade Switch

To engage the mower deck blades, pull the knob
up; the blades are disengaged when the knob is
pressed down.

Fuel Shut Off Valve

The fuel shut off valve is located at the left rear of
the seat. The valve is off when the handle tab is
turned perpendicular to the fuel line.

Service Meter

The service meter displays the total number of
hours the engine has run and indicates when the
engine and mower need servicing.
After every 50 hours of operation, an oil can icon
will appear and stay on for two hours, before
an automatic reset occurs. To manually reset
the meter, turn the key off and on five times at
one second intervals. To service the engine and
mower, see the Service Journal of this manual.
NOTE: The service meter operates (clocks hours)
only when the engine is running. Be sure to turn
the key off when the unit is not in use, to prevent
meter hours from accumulating.

Cutting Height Lever

To set the desired deck cutting height, press the
release button and move the lever forward to the
cutting height pin. See Before Starting in the
Operation section to change the cutting height.
The cutting height range is from 1-1/2" (38 mm)
to 4" (102 mm) in 1/2" (13 mm) increments. The
heights are measured from the ground up to the
blade tip with the engine not running.
WARNING! Do not make adjustments
unless the engine is stopped and the park
brake is activated.
IMPORTANT INFORMATION Always raise the
deck to the highest position for transport.
