PRODUCT OPERATION
BEFORE STARTING
Before starting the roller screed, there are a few items that need to be checked to prevent damage or personal injury.
• Make sure that both plugs are securely fastened to the end of the roller tube, and will not vibrate loose.
• 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 screed run.
• Look over the forms to check for unevenness so that the screed tube will not hang up.
OPERATION
Operating your roller screed correctly will assist you in achieving the desired outcome of a pour. Follow the instructions
below to operate your screed correctly and you will be very pleased with your results.
• Engage the power unit, and begin to pull the roller screed over forms, a screed pipe, or screed rail, distributing the
concrete aggregate to the desired level.
• Each operator must properly maintain control of both handles, guiding the roller tube 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. It is important to
pay close attention to the aggregates, slump and concrete modifying agents so the operator can compensate the
speed of the motor adequately.
• Do not allow the roller screed to run in the same position for an extended period of time. If screeding is delayed, turn
the motor off and let the roller 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.
The roller screed is capable of running two motor heads at the same time, on either side of the roller tube. It is
recommended that two power ends are used for roller tube lengths 23’ and above.
IMPORTANT
If the roller screed is being used with two motor heads, one must be toggled in the forward position, and the other must be
toggled in the reverse position. The roller screed will not operate if the directions of the motor are the same. When pour is
completed, ensure screed is cleaned immediately to prevent concrete from curing in the motor drive shaft, motor enclosure,
handle joints or on the roller tube.
Cleaning the motor enclosure should be done by blowing compressed air into the enclosure and washing by hand – avoid
getting water directly into the motor assembly. Pressure washers are recommended for cleaning the roller tube, but should
NOT be used to clean the motor enclosure.
