THROTTLE ASSEMBLY CONNECTION
With the throttle lever pushed to the far right hold
the throttle adjustment cable so there is no slack
and then tighten throttle control adjustment screw
to clamp the cable in place.
WEIGHT ADJUSTMENT
The eccentric weight on the power head is fac-
tory set to its maximum force. This setting will
settle concrete with a 2” to 8” slump. The only time
weight should be adjusted is when the screed is
going to be used on unusually high slump con-
crete.
To change the force of vibration, adjust the posi-
tion of the eccentric weight as follows. Using a
¼” Allen key loosen the set screw on the thicker
weight. While holding the thick weight stationary
with the Allen key turn the thin weight by hand to
the desired position.
Turning the thin weight clockwise decreases the
force, it is zero when the flat edge of the thin
weight is parallel to the flat edge of the thick
weight with the set screw.
LEAST VIBRATION
Turning the thin weight counter clockwise increas-
es the force of vibration until the flat edge of the
thin weight is flush with the opposite edge of the
thick weight.
MAXIMUM VIBRATION (FACTORY SETTING)
OTHER SETTINGS
¾ VIBRATION
½ VIBRATION
