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.
• Make sure that both Ends are securely fastened to the end of the Pipe.
• Check all threaded connections to make sure that they are not loose.
• Check handles to make sure that they will not loosen or detach during the operation of the Spin Screed®.
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.
• 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. A reversing switch is located
on the Power Head.
• The Spin Screed® is meant to run at a slow speed. DO NOT open the Power Head and increase the drill 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 below).
It is important to pay close attention to the aggregates, slump, and concrete modifying agents to compensate the
speed of the motor adequately.
• Do not allow the Spin Screed® to run in the same position for an extended period. If screeding is delayed, turn the
motor 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 motor 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.
