Using The Blower
OPERATING TIPS
In the hands of an experienced operator,
the EB8510 can efficiently move a wide
variety of debris ranging from grass clip-
pings to gravel. As a general rule, operate
your blower at the lowest throttle setting
required to get the job done:
THROTTLE LIMITER
The EB8510RT 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 19.

Throttle Limiter
Lever
Figure 19
Throttle Limiter Adjustment
Throttle Control (EB8510RT)
Figure 18
To bring RPM down to idle, push lever
back up into original position.
Adjusting throttle limiter:
1. Remove the plug located at the top of
the throttle assembly. See Figure 20.
2. Move the throttle limiter lever to the
“dB” setting. See Figure 20.
3. With the engine running and while
depressing the throttle trigger, use a
small Phillips screw driver to turn the
adjustment screw clockwise to decrease
RPM and counter-clockwise to increase
until desired limited RPM is achieved.
4. Reinstall limiter adjustment plug.
Figure 20
Remove limiter
adjustment plug
Thumb Con-
trol Lever
The EB8510RT is equipped with a multi-
function 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
“Limiter” 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.
CRUISE FUNCTION
Using the right thumb, push the throttle
lock lever down until the desired RPM
setting is reached. See Figure 18.
NOTE:
With the throttle limiter adjusted to 3,850
RPM, the EB8510RT will have a sound level
of 65 dB(A) measured at 50 feet.
Adjusting The Harness
The Shindaiwa EB8510 Blower features an
advanced harness system that helps ensure
maximum operator comfort and ease of
operation. See Figure 17.
nThe shoulder harness is filled with soft
padding for reduced operator fatigue.
nThe simplified adjustment system
makes it easy to match the harness to
every body size and type.
