CONTROLS
11. 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.
In order to increase or decrease the engine
speed, the control is moved forward or
backward 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.
12. Blade switch
In order to engage the mower deck, pull the
knob out; the mower blades are disengaged
when the knob is depressed.
