Starting the Engine
The engine supplied with your Vibratory Screed is the Robin EX13 model. This engine
has a manual choke, manual throttle control and centrifugal clutch. This is a 4-cycle
engine which runs on “regular” gasoline and does not require oil to be mixed in the gas. In
addition to the recommendations below, follow the instructions for starting and operating
the engine as well as all safety instructions provided by the engine manufacturer.
Before starting, check to see that there is gasoline in the fuel tank. If the fuel level is
low, fill with fresh, clean “regular” gasoline. Do not add oil to the gasoline.
Close the manual choke all the way.
Pull the starting cord 3 or 4 times to introduce gasoline vapor into the cylinder.
Move the manual choke to its 1/2 closed position.
Gently pull on the starting cord until tension is felt. Ease on the cord to allow it to retreat
fully. Pull hard on starting cord. The engine should start with the first or second pull.
Once the engine is started, let it warm up. As it warms, gradually open the choke until
it is fully open. You may then begin to use the tool.
If the engine does not start or run properly following these procedures, check the
troubleshooting section in the engine manufacturer’s owners manual.
OPERATION
This Vibratory Screed tool is designed for leveling and settling freshly poured cement
in a form. This Owner’s Manual assumes that the operator has an understanding of the
use of concrete and cement products.
The site must be properly designed and prepared according to the intended use, local
building codes, and characteristics of the site.
The ground must be dug out, leveled or sloped appropriately, and the form created with
2x4 or 2x6 material. The form must be level or slightly sloped as desired. The screed
will ride along the upper surface of the form. The form must be sturdy and properly
staked into position.
If the Screed Boards exceed a length of 15’, use the Spreaders (37 and 38) to keep
the Screed Boards apart.
Pour in and spread the underlayment, which may be sand or gravel. If needed, position
rebar or mesh reinforcement. Expansion bars may also be positioned if needed.
Pour in the cement mixture, and spread it with shovels to fill the form and roughly
smooth the concrete.
Place the Screed on one end of the form and start the engine. To do this, turn the
engine switch to ON. Then pull on the engine throttle.
