Introduction
The Multiquip DuoScreed is a hand held vibratory screed
designed to strike-off and consolidate concrete slabs. It
is comprised of two major components, the power unit
(gasoline engine), and the strike-off blade. Generally
this screed operates ideally in concrete with a slump of 2
inches or greater. Its applications include patios, driveways,
sidewalks and floor slabs.
Assembly
There are no tools required to assemble the DuoScreed.
The power unit (engine) is connected to the to the blade by
means of a spring-loaded clamp. Springs within the clamp
assembly prevent vibration from loosening the power unit
from the blade.
Handle Adjustments
The handle assembly on the DuoScreed is height
adjustable for operator comfort. The handle design used
on this screed allows the operator to remain upright at all
times and can be quickly adjusted without any tools.
Vibratory System
The vibratory system of the DuoScreed produces low
amplitude high frequency vibrations, designed to level and
compact concrete. This vibratory system is mounted at an
angle to transmit vibration laterally and vertically through
the blade to produce a strong, dense slab.
The engine drives a two piece eccentric weight by means of
a one-piece flexible shaft. This weight produces a vibratory
action which simultaneously allows the DuoScreed to level
the slab and consolidate the concrete beneath the surface.
Blades
The DuoScreed can utilize various blade widths. This
screed uses a lightweight (LW) type blade. The widths
can range anywhere from 6~16 feet (1.82~ 4.87 meters).
See Table 1 for more detailed information. Since different
length blades will require varying amounts of vibration, the
DuoScreed features adjustable eccentric weights.
NOTICE
Some blade widths may not be available. Please
contact MQ unit sales for available blades.

GENERAL INFORMATION
Engine
The Multiquip DuoScreed is equipped with a Honda Model
GX35SAT, 1.6 HP, mini 4-cycle gasoline engine. This
engine is lightweight and requires no fuel mixing.
Drive System
The Honda 1.6 HP engine drives a flexible shaft that
requires no greasing. Its short one piece design runs
directly to the vibrator housing and does not bend. This
type of design eliminates a major source of friction and
reduces the likelihood of shaft failure.
