ASSEMBLY GUIDE
Instructions for installing Roller Screed ends:
Live end installation. The end assemblies must be installed very rmly in the Roller Screed tube so
that they will not come out during use. At least 60 to 70 ft-lbs of torque must be used when installing
the ends.
FIRST: Remove the allen head set screw from the live end assembly.
SECOND: Grip each of the aluminum tapered discs with your hands and spin each end of the
assembly so that the rubber gasket swells up between the aluminum discs. Tighten the assembly
until the gasket swells up to the point so that when it is slipped into the tube there is some friction
between the rubber gasket and the inside of the roller tube. When you have done this, you will be
able to tighten the assembly with a pipe wrench mounted on the knurled portion of the universal joint
assembly. During the initial tightening phase, you will also need to hold the outside exposed edge of
the aluminum assembly with one hand so that it does not rotate inside of the tube. As soon as the
rubber gasket has a good grip inside of the tube, you can then hold one hand on the chain clamp vise
grip and the other hand on the pipe wrench and tighten very tightly. It is impossible to hold the tube
rmly enough to produce the necessary toque without using some mechanical means. Simply having
a co-worker hold the tube with their hands while you tighten the end with a wrench will not produce
the necessary torque. You may tighten this to the point where the inner beveled components of the
live end assembly come in contact with one another. You will feel the bolt you are tightening “bottom
out” and can no longer be turned. Back the bolt off to the nearest slot and insert the allen head set
screw. Installing the allen head set screw completes the installation of the live end and allows the
electric power head to be operated either in the forward or reverse direction without the assembly
becoming unthreaded. The electric power head has been set as the factory to the proper speed of
300 rpm. Never attempt to operate at a higher rpm.
The dead end can simply be tightened with an open end wrench as shown in photo N after following
the “hand tighten” procedure outlined above. The dead end should be lubricated from time to time
using the grease zerk.

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.

MAINTENANCE
After each use, ensure the roller screed is cleaned and stored carefully. Find a secure storage location for the roller tube
which will prevent any objects from falling on, or damaging it.
After every three to four uses, lubricate the lag end cap through the grease fitting using a standard lever-action grease gun.
After each use, blow pressurized air into the motor enclosure to ensure there is no debris buildup that could potentially
compromise the usage of the motor.
TROUBLESHOOTING
If the roller screed is not spinning or functioning properly, refer to the following guide to diagnose and resolve your issue.
• Check to see if the power is connected – to both the roller screed motor and the source.
• Disconnect the power source and check if the motor shank is tightly connected to the chuck. If tightening is required, use
the included chuck key to fully tighten the chuck to the motor shank.
• Disconnect the power source and check if the end plugs are fully tightened. Tighten them if required.
• Ensure the motor speed is set at the manufacturer default slow speed (300 RPM), and that it has not been shifted into
the high speed (1200 RPM). High speed will not result in better performance and may overheat the motor.
• Refer to the motor manufacturer’s manual for additional troubleshooting in regards to the specific device.
• If the roller screed is operating with two motor heads, ensure the heads are toggled to spin opposite directions. If both
motor heads are set to spin in the same direction, the roller screed will not function properly.
