DSGPULW DUOSCREED — SILICOSSISWARNING  
WARNING WARNING  
SILICOSIS WARNING  
RESPIRATORY HAZARDS  
Grinding/cutting/drilling of masonry, concrete, metal and  
other materials with silica in their composition may give  
off dust or mists containing crystalline silica. Silica is a  
basic component of sand, quartz, brick clay, granite and  
numerous other minerals and rocks. Repeated and/or  
substantial inhalation of airborne crystalline silica can  
cause serious or fatal respiratory diseases, including  
silicosis. In addition, California and some other  
authorities have listed respirable crystalline silica as a  
substance known to cause cancer. When cutting such  
materials, always follow the respiratory precautions  
mentioned above.  
Grinding/cutting/drilling of masonry, concrete, metal and  
other materials can generate dust, mists and fumes  
containing chemicals known to cause serious or fatal  
injury or illness, such as respiratory disease, cancer,  
birth defects or other reproductive harm. If you are  
unfamiliar with the risks associated with the particular  
process and/or material being cut or the composition of  
the tool being used, review the material safety data  
sheet and/or consult your employer, the material  
manufacturer/supplier, governmental agencies such as  
OSHA and NIOSH and other sources on hazardous  
materials. California and some other authorities, for  
instance, have published lists of substances known to  
cause cancer, reproductive toxicity, or other harmful  
effects.  
Control dust, mist and fumes at the source where  
possible. In this regard use good work practices and  
follow the recommendations of the manufacturers or  
suppliers, OSHA/NIOSH, and occupational and trade  
associations. Water should be used for dust  
suppression when wet cutting is feasible. When the  
hazards from inhalation of dust, mists and fumes cannot  
be eliminated, the operator and any bystanders should  
always wear a respirator approved by NIOSH/MSHA for  
the materials being used.

before starting.  
DANGER - READTHIS MANUAL!  
Failure to follow instructions in this manual may lead to  
serious injury or even DEATH! This equipment is to be  
operated by trained and qualified personnel only! This  
equipment is for industrial use only.  
NEVER operate the DuoScreed in an explosive  
atmosphere or near combustible materials. An explosion  
or fire could result causing severe bodily harm or even  
death.  
NEVER touch the hot exhaust manifold,  
muffler or cylinder. Allow these parts  
to cool before servicing engine or  
generator.  
The following safety guidelines should always be used when  
operating the MQ DSGPULW DuoScreed.  
General Safety:  
DO NOT operate or service this  
equipment before reading this entire  
manual.  
HighTemperatures – Allow the engine  
to cool before performing service and  
maintenance functions. Contact with hot! components  
can cause serious burns.  
The operator MUST BE familiar with proper safety  
precautions and operations techniques before using  
generator.  
The engine of the DuoScreed  
requires an adequate free flow  
of cooling air. NEVER  
operate the DuoScreed in any  
enclosed or narrow area where  
free flow of the air is restricted.  
If the air flow is restricted it  
will cause serious damage to  
the engine and may cause injury to people. The  
DuoScreed's engine gives off DEADLY carbon monoxide  
gas.  
This equipment should not be operated by persons under  
18 years of age.  
NEVER operate this equipment without proper protective  
clothing, shatterproof glasses, steel-toed boots and other  
protective devices required by the job.  
NEVER operate this equipment when not  
feeling well due to fatigue, illness or taking

DSGPULW DUOSCREED — GENERAL INFORMATION  
The blade of the DuoScreed offer a unique design with two  
distinct edges and is manufactured from reinforced extruded  
aluminum alloy. A curled edge is provided for applications that  
allow the blade to ride on top of forms or rails. A smooth edge is  
provided for wetscreed applications where the machine rides  
entirely on concrete. Plastic end caps allow the blade to maneuver  
around obstructions without marring the surface.  
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.  
Engine  
Assembly  
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.  
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.  
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.  
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.  
Maneuverability  
The HD blades have end caps and are available in the lenghts  
referenced inTable 1.End caps are provided on each side of the  
DuoScreed's blades to allow the screed to be easily maneuvered  
around pipes or obstructions.End caps are not used on the LW  
blades.  
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.  
Transport  
To transport your DuoScreed simply unclamp the power unit  
from its base. Additionally, the handles can be folded down  
for storage. The power unit weighs approximately 29 lbs.  
(13.0 kg), while the HD blades weigh approximately 2.8 lbs/  
ft. (4.2 kg/m) and the LW blades weigh 1.95 lbs/ft (2.9 kg/m)  
Figure 2 shows the location of the components of the  
DuoScreed. The function of each component is described  
on the next page.  
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. The type of  
blades are defined as heavy duty (HD) or lightweight (LW).  
The widths can range anywhere from 6~20 feet (1.82~ 6.00  
l
meters).SeeTable 1 for more detailed information.Since different  
length blades will require varying amounts of vibration, the  
DuoScreed features adjustable eccentric weights. It is also  
recommended that two power units be used if 18~20 foot (5.48~  
6.0 meters) blades are required.  
Some blade widths may not be  
available. PleasecontactMQunitsales  
for available blades.
