DS-SERIES DUOSCREED — PARTS & OPERATION MANUAL — REV. #0 (09/19/01) — PAGE 9

DS-SERIES DUOSCREED — GENERAL INFORMATION

Introduction

This 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. It takes approximately 2 minutes to assemble the DuoScreed.

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.

Engine

The DuoScreed is equipped with an Honda Model GX31SA, 1.5 HP, mini 4-cycle gasoline engine. This engine is lightweight and requires no fuel mixing.

Drive System

The Honda 1.5 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

End caps are provided on each side of the DuoScreed's blades to allow the screed to be easily maneuvered around pipes or obstructions.

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 weights approximately 34 pounds while the blades weigh approximately 2.8 pounds per foot.

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 blades ranging in lengths from 4.9 to

19.6 feet (1.5 to 6 meters). 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 16, 18, or 20 foot blades are required.

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.

DS-SERIES DUOSCREED — ASSEMBLY INSTRUCTIONS

Eccentric Weight Adjustment

There are two eccentric weights (Figure 6) that are supplied with the DuoScreed. These weights are located inside the eccentric weight compartment, which is located at the bottom of the unit.

Figure 6. Eccentric Weight Location

These weights determine the amount of vibration that will travel down the blade. Depending on the type of blade that is used, will determine the position of the two eccentric weights. Reference Figure 7 in determining how your eccentric weights should be positioned.

1. To gain access to the eccentric weight compartment, loosen

the two wing nuts on each side of the compartment and lift the cover.

2. Loosen the eccentric locking wing nut.

3. Use the chart in Figure 7 to determine what position your eccentric weights should be in (position 1, 2 or 3).

Example:

A 13.9 ft. (4.25 meters) blade will place the eccentric weights in position 2.

Application/Operation

DS-SERIES DUOSCREED — APPLICATION/OPERATION

1. Before placing the DuoScreed in concrete for screeding, it is a good idea to apply frame parts that may come in contact with the concrete. This form oil will become useful when cleaning the DuoScreed. Make sure to amount of form oil.

2. Prepare a grid of #5 rebar pins (Figure 14) equally spaced approximately every 9 to 11 feet. If a 10 ft. screed blade is going to be used space the grade pins every 9 feet, if a 12 ft. screed blade is required, space the grade pins every 11 ft. Make sure to drive the pins deeply into the ground.

3. Use a

4. Once all the grade pins have been placed correctly and are dead on grade, concrete can then be poured on top of grade pins.

5. Level, and form the concrete as close as possible to grade. Mark the top of each pin so that its exact location will be known. Use a hand trowel to float the edges and plumbing grade pins.

6. If chalk lines are used for grade against forms, walls or existing concrete, float out the grade with a hand float along the edge.

7. Two workers will be required to assist the DuoScreed operator when making the 12-18 concrete bases, one on each side. These workers will rake the concrete in toward the center of the DuoScreed away form the bases to avoid changing base elevation.

9. To begin screeding move the engine throttle lever (Figure

15) midway between idle and full throttle. Notice that the DuoScreed's vibration will cause the blade to sink into the concrete base until it touches the top of the grade pins

10. Pull the DuoScreed from the edge of the grid's corner, horizontally toward the DuoScreed passes over the grade pins a small circle of concrete around the grade pins will appear. This indicates that the Duoscreed has vibrated the grade pin, and that the operators is

11. Keep the DuoScreed blade level and create a level base between 12-18 inches wide.

12. After a complete pass over the first set of grade pins has been made, remove the DuoScreed from the concrete base and position it over the second set of grade pins (Figure 16), overlapping the first set of grade pins between 12-18 inches. Repete this process until all grade pins have a level base between 12-18 inches wide.

DS-SERIES DUOSCREED — APPLICATION/OPERATION

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

troubleshooting section of this manual.

■

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.

slab. If the DuoScreed is vibrating too strongly the

will require adjustment. Refer to the

level, hard

■

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, DO NOT attempt to lift it. Quickly increase engine rpm's while pushing forward on the handles to free the machine.

Maintenance

3. Use a low pressure water hose, soft brush, wiping cloth

CAUTION:

DO NOT clean the DuoScreed with a

pressure washer

1. NEVER clean the DuoScreed with the engine running.

2. Allow the engine to cool down before cleaning.

NOTE

DO NOT allow concrete to

Drain the fuel tank completely. Run the engine until the fuel in the injection system is

completely consumed.

Completely drain used oil from the engine crankcase and fill with fresh clean oil, then follow the procedures described in the engine manual for engine storage.

Cover DuoScreed and engine with plastic covering or equivalent and store in a clean, dry place.

Air Cleaner

1. The air cleaner element should be cleaned because a clogged air cleaner can cause poor engine starting, lack of power and shorten engine life substantially.

2. Before opening the air cleaner compartment, wipe any dirt or foreign matter from the air cleaner body and cover, using a moist cloth. Be careful to prevent dirt from entering the carburetor

3. Press the latch tab on the top of the air cleaner cover (Figure

16), and remove the cover. Check the filter to be sure that it is clean and in good condition.

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 mm).

6. Carefully install the spark plug by hand to avoid cross threading, the tighten
