DSGPULW DUOSCREED — SILICOSSIS WARNING
WARNING
SILICOSIS WARNINGRESPIRATORY 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.
WARNING
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.

DSGPULW DUOSCREED — GENERAL INFORMATION
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. The type of
blades are defined as
The widths can range anywhere from 6~20 feet (1.82~ 6.00
meters). See Table 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.
heavy duty
(HD) or
l
lightweight
(LW).
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.
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.
Maneuverability
The HD blades have
referenced in Table 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.
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)

Important Tips to Remember
■
Do not allow the engine to run out of fuel as this may cause
problems with starting. Always maintain an extra supply of
fuel on the job site.
■
Always keep the DuoScreed moving backwards during
operation. Allowing the DuoScreed to vibrate in the same
location for too long will cause it to sink into the concrete.
■
When using the DuoScreed with low slump (dry) concrete do
not attempt to walk it quickly across the slab. Walk slowly to
allow the vibratory action to consolidate and level the slab
surface. When using the DuoScreed with high slump (wet)
concrete you will be able to walk the machine across the slab
at a faster pace.
■
In applications where the Duoscreed is being used as a wet
screed it is recommended that grade or height of the concrete
slab be adjusted with a laser device.
■
Proper vibratory force is essential to producing a
durable
eccentric weights

■
When screeding using forms or rails, always size your screed
blade appropriately for the job. It is best to have the blade
extend beyond the forms, by about 6-inches on each side.

will require adjustment. Refer to the

,
When screeding make sure the blade is kept straight. DO
NOT let blade turn.
DO NOT run the DuoScreed with one part of the blade on
forms and the other on base. The blade must either be placed
on forms or float (wet screeding), but not a combination of the
two techniques.
DO NOT stand in the concrete with the engine throttle
engaged. This will cause the DuoScreed to sink.
If the concrete appears too wavy, you are moving too slowly,
increase your backing-up speed.
Always keep the workers back far enough too allow the
operator to see the cutting face of the blade as it rides on the
wet screed base.
The operator should keep the screed blade about 1/8 to 1/4
inch above the concrete base at all times.
Should the DuoScreed stick to the wet concrete slab, DONOT attempt to lift it. Quickly increase engine rpm's while
pushing forward on the handles to free the machine.

3.Remove the spark plug with 5/8-inch wrench.
4. Inspect the spark plug. Replace it if the electrodes are worn,
or if the insulator is cracked or chipped. Clean the spark
plug with a wire brush if you are going to reuse it.
5.Set the spark plug gap (Figure 18) using a suitable gauge.
The gap should be between 0.024-0.028 inch (0.60-0.70
