ASSEMBLY GUIDE

1. Lay out all the components of the Spin Screed® Assembly. Note: Pipe sold separately
   

2. Squeeze the buckle release to open the filter cover and access the throttle connection point.
   

3. Ensure that the throttle adjuster is threaded onto the throttle cable (G) end and hook the cable end into the throttle linkage.
   

4. Swivel the throttle adjuster into the adjustment bracket, with the jam nut on one side and the full-sized nut on the other.
   

5. Tighten the nuts to secure the throttle adjustment bracket then close the air filter cover.
   

6. Attach handle bar (A) to end of shaft using (2x) 5/16″-18 UNC x 2″ LONG HHCS, washers and nuts (included). Prior to tightening the handle bar on the end of the  shaft, select right- or left-handed throttle lever position by flipping handle bar over and adjust the balance of the handle bar (left to right) to achieve best handling for the  specific application.
   Attach both parts of the Dead-End T-Handle (D) and screw in the handle components (E). NOTE: It is best to have the hole at the end perpendicular to the T-Handle.

7. Remove the cover and gasket from the throttle lever.
   

8. Hook the throttle cable end into the throttle lever linkage.
   

9. Re-Install the gasket and cover onto the throttle lever.
   

10. Take the Small Tool (F) from the Handle (A). Remove the power axle from Live End (J) by depressing the spring with the Small Tool. Return the Small Tool to the Handle.

11. NOTE: Ends (I&J) must be installed in screed pipe before these steps. See next page. Connect the Power Head (B) by depressing the locking pin on the power axle  which is installed in the Live End (J). Insert the square drive lug on the power axle into the Live End (J) pivot coupling. Check to assure the catch pin has popped into  the pivot coupling by trying to pull it away from the Power Head (B).

12. For safety, cover the exposed axle (the side not being used) with the Safety Boot (C) and attach to the gearbox with hardware provided.

13. Connect the T-Handle (D) to the Dead End (I) by removing the Pin (H), placing the T-Handle through the opening and replacing the Pin.

INSTALLING PIPE ENDS

Step 1 – You’ll need: 12″ Pipe Wrench, 9″ Chain Clamp Vice Grip, and a 5/16″ Allen Wrench. Use the Chain Clamp Vice Grip to hold the Pipe (Note: Do not attempt to or  have a co-worker hold the Pipe. You will not be able to produce enough the torque necessary to tighten the Ends).

Step 2 – Insert the Live End (J) into the Pipe, make sure set screw is removed.

Step 3 – Use the Pipe Wrench to tighten the Live End (J) (Note: the Live End should be secured very tightly). Make sure it is lined up with the set screw opening.

Step 4 – Insert set screw and tighten using the 5/16″ Allen Wrench.

Step 5 – Insert the Dead End (I) into the Pipe.

Step 6 – Use the Pipe Wrench to tighten the Dead End.

PRODUCT OPERATION

BEFORE STARTING
Before starting the Spin Screed®, there are a few items that need to be checked to prevent damage or personal injury.

• Affix safety boot (C) to unused side of screed power unit to cover rotating axle. Uncovered rotating axle may entangle footgear, causing injury.
• Make sure that both Ends (I&J) are securely fastened to the end of the Pipe.
• Check all threaded connections to make sure that they are not loose.
• Check handles (D&E) to make sure that they will not loosen or detach during the operation of the Spin Screed®.

ENGINE MAINTENANCE RECOMMENDATIONS
Replace oil in engine with Honda #08209-10W30 oil after first 20 hours of operation. Replace again after next 40 hours of operation. Using Honda

08209-10W30 product  will prevent overfilling the engine. Failure to replace

oil will dramatically reduce engine life. See GX35 engine user’s manual for operation of engine choke for cold startup and further maintenance recommendations.

OPERATION
Operating your Spin Screed® correctly will assist you in achieving the desired outcome of a pour. Follow the instructions below to operate your screed correctly.

• Start engine. Refer to Honda GX35 owners manual for basic starting instructions.

• Engage the power unit and begin to pull the Spin Screed® over forms, screed pipe, or screed rail, distributing the concrete aggregate to the desired level. Make sure the Pipe is spinning away from you.

• The Spin Screed® is meant to run at a slow speed.

• Each operator must properly maintain control of both handles, guiding the Pipe over the concrete aggregate at a speed and direction best suited for the aggregate’s  respective slump.

• DO NOT allow either end of the unit to enter wet concrete. Keep each end on the forms, screed pipes, or screed rails to prevent contamination of the plugs or motor.

• If the concrete is not being added at the appropriate rate, slow the screed down to compensate.

• The speed at which the screed should be pulled back and forth depends on the slump of the concrete (see slump
  guidelines below). It is important to pay close attention to the aggregates, slump, and concrete modifying agents to
  compensate the speed of the engine adequately.

• Do not allow the Spin Screed® to run in the same position for an extended period. If screeding is delayed, turn the engine off and let the Spin Screed® sit in a position  where it is best suited to start again. When the placement of aggregate resumes, slowly engage the engine and continue screeding.

SLUMP GUIDELINES
The Spin Screed® will handle stiff concrete having only a 3-inch slump. When you first start using the Spin Screed®, pour with a slump level that is consistent with your past  practices. As with any new tool, certain operation techniques must be learned.

STRAIGHT PULL METHOD – WET CONCRETE OPERATING METHOD ONE
Slump levels of 5 or more, maintain 1 to 2 inch surcharge

When working with wet concrete, start the Spin Screed®, squeeze the throttle lever, and slowly pull it over the concrete while muckers maintain about a 2-inch surcharge of concrete in front of the screed. After advancing 6 to 8 feet, allow the spinning Spin Screed® to move slowly backward over the freshly screeded concrete. This slow backwards pass pushes aggregate left on the surface down while bringing paste to the surface. After backing over the poured section, slow down the Spin Screed® and pull the screed back to the area where more concrete has been placed. Begin screening again. With concrete wetter than a 5-inch slump, pulling over the concrete surface a second time with the motor running will produce a flatter surface with sufficient paste for floating. Examine the surfaces prepared by the Spin Screed® and adjust your technique to product the desired surface for floating.

BUMP AND RUN METHOD – STIFF CONCRETE OPERATING METHOD TWO
Slump levels of 3 to 4 inches, maintain 2.5 to 3.5 inch surcharge

With stiff concrete, pulling the Spin Screed® over the concrete produces a rough surface that is difficult to float. To get the best results, use the “bump and run” technique. Start by squeeLing the throttle lever to start the Spin Screed® and gently bumping a 2-3-inch surcharge with the Spin Screed®, causing it to advance a few inches, and then allow it to retreat 4 to 6 inches. Advance the Spin Screed® again. Continue the “bump and run” technique until you have advanced 6 to 8 feet, then allow the Spin Screed® to move backward slowly over the freshly screeded concrete with the Spin Screed® still running. This slow backwards pass pushes aggregate left on the surface down while bringing paste to the surface. After backing over the poured section, turn off the Spin Screed® and pull the screed back to the area where more concrete has been placed. Begin screeding again. The screeded section is ready for floating and should be done immediately. When screeding stiffer concrete, pulling the Spin Screed® forward a second time tends to remove the layer of paste that has been worked to the surface and makes the surface more difficult to float and finish.

IMPORTANT
Ensure the Spin Screed® is cleaned immediately after use to prevent concrete from curing in the engine drive shaft, engine enclosure, handle joints, or on the Pipe.
Cleaning the engine should be done by blowing compressed air and washing by hand—avoid getting water near the carburetor. Pressure washers are recommended for cleaning the Pipe but should NOT be used to clean the engine or gear box.

MAINTENANCE

After each use, ensure the Spin Screed® is cleaned and stored carefully. Find a secure location for the Pipe to prevent any objects from falling on or damaging it.
After every three to four uses, lubricate the Dead End Pipe Adapter through the grease fitting using a standard lever-action grease gun.
Prior to starting the engine, add engine oil at the fill port at the base of the engine.
THE ENGINE WAS SHIPPED WITHOUT OIL IN THE CRANKCASE. A small bottle is included with the product which corresponds with the precise amount needed.
Retain the bottle for future measuring purposes.
Following first 20 hours of run time replace the engine oil. The oil is drained by removing the drain plug from the base of the engine and tipping the engine.
Fill only the amount recommended by engine manufacturer — DO NOT OVERFILL THE ENGINE.
Engine oil is to be replaced after every subsequent 40 hours of use.
Check sponge air cleaner by squeezing the plastic intake cover catches and pull it off. The air cleaner can be rinsed with water. Be sure to squeeze out as much water as  possible prior to replacing.
The gearbox is delivered fully greased. After approximately 40 hours use it is recommended that the user inject NLGI #0 Lithium Grease into the zerk mounted on the side  of the gearbox. The drain screw must be removed to allow old grease to escape. Be sure to replace drain screw when finished.
Repeat grease replacement every 40 hours.

TROUBLESHOOTING

If the Spin Screed® is not spinning or functioning properly, refer to the following guide to diagnose and resolve your issue.

• Refer to Honda GX35 owner’s manual for engine troubleshooting.
• Check if the end plugs are fully tightened. Tighten them if required.
