Operating Blower
WARNING!
Engine exhaust IS HOT, and contains Carbon Monoxide (CO), a poison gas. Breathing CO can cause un-
consciousness, serious injury, or death. Exhaust can cause serious burns. ALWAYS position unit so that exhaust
is directed away from your face and body.
WARNING!
Always wear safety glasses, hearing protection and a face filter mask or serious personal injury may result.
Do not point the blower pipe in the direction of people or pets.
IMPORTANT!
Use reduced speed only when performing light-duty tasks or to comply with local noise regulations. Continuous
low speed operation may allow fuel/oil residue to build-up on the piston and cause rapid build-up of carbon on
the spark arrestor screen, resulting in overheating and engine damage. To reduce harmful build-up, run engine
at wide open throttle for at least 5 minutes every hour, and inspect/clean the spark arrestor screen after
approximately 40 hours of operation.
The EB254 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
min-1 (rpm) setting is reached. See Figure 10.
To bring RPM down to idle, push lever back up into original position.
Throttle Limiter
The EB254 has a throttle limiter function 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 11.
Adjusting Throttle Limiter:
1. Remove the plug located at the top of the throttle assembly. See
Figure 12.
2. Move the throttle limiter lever to the “dB” setting. See Figure 12.
3. With the engine running and while
depressing the throttle trigger, use a small cross head screw driver
to turn the adjustment screw clockwise to decrease min
-1
(rpm) and
counter-clockwise to increase until desired limited min
-1
(rpm) is
achieved.
4. Reinstall limiter adjustment plug.
