Throttle Limiter
The RT blower has a throttle limiter func-
tion that allows the operator to pre-set the
maximum engine speed. This is useful for
reducing the noise emitted by the blower
in noise sensitive areas.
Setting Throttle Limiter:
For reduced noise setting, move the
throttle limiter located on the right side of
the throttle control to the dB setting. See
Figure 18.

The RT blower is equipped with a multi- func-
tion throttle control. The “Cruise” function
allows the operator to use a thumb controlled
lever for constant speed use without using the
throttle trigger. This is useful for limiting the
fatigue caused from holding the throttle for
extended periods of time.

On the opposite side, a two position “Lim-
iter” control allows full engine speed when
set for “Turbo” or limits the throttle to a
pre-set engine speed when set to low noise
(dB) setting.
Using the right thumb, push the throttle lock
lever down until the desired min
-1
setting is
reached. See Figure 17
