Throttle Control; Blade Switch; Service Meter; Choke Control - Husqvarna MZ52 Operator's Manual

Throttle Control

The throttle control regulates the engine speed and thereby
the rate of rotation of the blades, assuming the blade switch is
pulled out, see Engaging the Mower Deck.
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, pull the knob out; mower blades
are disengaged when the knob is pressed down.
CONTROLS

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 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.

Choke Control

The choke control is used for cold starts in order to provide the
engine with a richer fuel mixture.
For cold starts the control should be pulled out to its extent.
