B.PUTTING INTO SERVICE
The purpose of the instructions section of this manual is to
explain the intended setup, use and maintenance procedures
recommended by Whiteman Industries.
Before packaging and shipment, this Whiteman Ride-on Roller
Screed was run and tested at the factory. If there are ANY
problems, please contact the Multiquip Service Department.
Make sure that all manuals and instructions are read carefully before putting your new Whiteman Roller Screed into
service. Improper setup, use or maintenance of this equipment could result in personnel injury or damage to the equipment. Listed in Figure 2, are the location of main parts
described in the next section.
The power unit comes completely assembled. However,
before operating the screed, the hydraulic strike tube motor
from the power unit must be bolted to the motor mount, which
comes with the screed, as shown in Figure 3. This takes
two bolts, ½ X 1-1/2.
IMPORTANT: If you change power units, leave the strike
tube motor mount with the roller screed for the next power
unit
.
Figure 3. Strike Tube Motor Assembly
D. ROLLER SCREED ASSEMBLY
2.Description
The WRS 5200 Ride-On Roller Screed is made up of truss
sections (Figure 4) which vary in length from 3 to 9 feet.
These truss sections support the 6 inch tubing (strike tube)
which runs along the front of the machine. This strike tube
comes in four different lengths, 8, 14, 16 and 18 feet. By
coordinating the truss section and strike tube lengths, various roller screed lengths can be assembled.
Table 2 shows the different combination of truss
sections and strike tube lengths to get the desired
roller screed length. Dimensions are in feet
* Actual concrete form width should be at least 2 foot less than screed length.
** Left side of Table I in the truss section represents the power unit end
It is important in the assembly of the roller screed to keep
truss sections on the appropriate side. To help with this,
each truss section is stamped with a letter and a number.
This stamping is located on the top pipe of each section.
For example, L14, would represent left or the power
unit end and combine this section (9 feet) with the
end section (5 feet), gives you 14 feet. This is the
strike tube length. The stamping on the 9 foot truss
section would be L14. Examples of the assembly for
different screed lengths are shown in Appendix C.
2.Assembly of the Roller Screed
To begin with, bolt together truss sections that match the
length of the strike tubes desired. Find the length of roller
screed wanted in the Appendix C and match the strike tubes
and truss sections. Use 1-1/2” long bolts where 2 joints
come together and 1-3/4” long bolts where 3 joints meet.
Don’t bolt truss sections from other strike tube lengths together yet.
As an example, the assembly of a 44’ roller screed is shown.
First check the Appendix C and find the length of screed
wanted. Lay the parts as shown in the drawing out in the
assembly area. Assemble the truss sections to match the
strike tube lengths. For this screed, the strike tube lengths
are 14’, 16’ and 14’. The following Figures, 4, 5 and 6, are
the truss sections assembled to match the strike tubes.
Task 1.
Assemble right, left and middle truss sections. See Figures
5, 6, and 7.
As an example, the assembly of a 44’ roller screed is shown.
First check the Appendix C and find the length of screed
wanted. Lay the parts as shown in the drawing out in the
assembly area. Assemble the truss sections to match the
strike tube lengths. For this screed, the strike tube lengths
are 14’, 16’ and 14’.
Take the middle bracket and insert the splined shaft of it into
the other end of the strike tube as shown in Figure 9. Slide
the middle bracket pins into the section just made.
Figure 7. Left Section 14 Feet
Task 2.
Once the assemblies mentioned above are finished, start
on one end, take the strike tube and insert it into the 1-3/8
bearing mounted on the outer plate as shown in Figure 8.
The 1-5/8 nut and jam nut should be turned in until they are
against the strike tube hub.
If another middle bracket is not required, go to the next paragraph. Two middle brackets are required for three strike tubes,
one for two strike tubes. If another middle bracket is required, insert the middle strike tube into the splined shaft of the
middle bracket mentioned above. Assemble the truss sections and middle bracket using the ½ X 1-3/4 bolts. Working your
way across, take the next middle bracket and insert the splined shaft into the middle strike tube as shown in Figure 9 & 10.
Figure 10. Middle Section
Task 5
Now go to the other end of the roller screed, take the strike
tube there and insert it into the second middle bracket’s
splined shaft. As you pull the last 14’ section (Figure 7) into
place, insert the end of the strike tube into the bearing as
you did in Figure 7. Use ½ x 1-3/4 bolts to bolt the two truss
sections and the middle bracket together.
Task 6.
Once the truss sections are together, string the four long
hydraulic hoses through the middle of the trusses. Two male
and two female quick connects are required at the other
end, one male and female of the 5/8” hose and the same for
the ½” hose.
Task 7.
Put the tarps on the appropriate section. The section of the
tarp where two nylon straps are close together should fit
over a truss joint. All tarps were made to full length per
section.
The tarp for the right section (13’11”) will have two places for
the truss joint. It will have a 4 foot section (which for this
set-up will be folded back under the next section of tarp) and
a 6 and 3 foot section
.
The middle tarp (16’) has a place for the truss joint right in
the middle.
The left tarp (13’5”) has one truss joint located 4 foot in from
the end. For this set-up, the 4 foot section will be folded
back under the 9 foot.
The buckles on the tarp should be on the back side (strike
tube is on front side) and the tarp drain hole on the bottom
when finished.
Task 8.
Two more items need to be added on the outside of the
tarps. These are the 50 foot electric cord and the pump
lever cable. Before buckling the tarp, put the cable and cord
behind enough buckles to hold them in place.
Task 9.
Adjust the 1-5/8” nuts on the strike tubes next to the outer
plates so the other end of the strike tube next to the middle
bracket is spaced from 1/16 to 1/8.”
Place the power unit on the appropriate end and the roller
screed is ready to use.
D.HANDLING
1.Moving the Machine
WARNING!
DO NOT ATTEMPT TO LIFT THE SCREED
FROM THE MIDDLE SECTIONS.
Your Whiteman roller screed was designed to be moved
and handled in several ways. Casters that can be lowered
are provided to move the machine on and off forms and for
moving short distances. When using the casters and
moving short distances, the power unit may be left on the
roller screed.
⇒
When lifting the roller screed to load for transporting or
other purposes, the power unit should be taken off.
⇒
Care should be taken to lift the machine correctly. With
a fork lift, one end at a time can be lifted onto the transport. Lifting straps should be placed around the top pipe
in the 5’ end sections. Figure 10 illustrates the recommended lifting points.
⇒
Care should These lifting positions are the same for both
ends. Attach a lifting strap to one of these points. The
safety snap pins in the top turnbuckles of the truss sections are not designed to carry the weight of the machine during lifting. The top of the truss sections should
always be kept in compression. Lifting with straps or
forks from center sections may damage the machine or
bend these pins. Figure 11 shows lifting points A & B.
Lifting point “B” can be used with any screed length while
lifting point “A” should only be used for screed lengths
longer than 32 feet.
If lifting the roller screed is planned for transporting or other
reasons, some precautions should be followed.
WARNING!
NEVER TRANSPORT SCREED WITH
THE POWER UNIT ON THE MACHINE
The strike tubes are a critical component of the roller screed.
If the strike tubes are damaged, it is possible they will not
turn true. Care should be taken to store extra tubes on a
fully supported level surface. Never lift the unit from the
strike tubes.
E.Removable Components
The seat section and power unit are removable. Having
these pieces removable means you can easily take most of
the critical components from the machine with you. This
provides a way to better care for your equipment between
jobs.
To remove the seat, undo the cord and cable from the power
unit and the quick connect hydraulic lines from the stack
valve. Windup the cord and cable.
To remove the power unit, attach lifting straps, front-left and
back-right and lift with fork lift.
NEVER DISABLE OR DISCONNECT THE
EMERGENCY KILL SWITCH.
Your Whiteman Ride-On Roller Screed is equipped with a
safety emergency kill switch. Note: It is provided for operator safety and injury may result if it is disabled, disconnected
or improperly maintained.
Below the kill switch is the “High/Low” toggle switch. This
throttle switch has only two positions.
The choke button is to the right of the Hi/Low switch. To
activate this switch, you must hold it down.
2.Light Switch.
The light switch is located on the fuse box which is mounted
on the radiator end of the power unit.
3.Drive Tube Speed Control Lever (Figure 13).
Located on the far left, above the electric box, this long
handle controls the variable speed of the drive tubes. This
lever should be in the “Straight Up” position when starting
the engine.
THE THROTTLE CONTROL CANNOT BE USED TO STOP THE EN-
GINE.
4.Drive Tube Direction Control Levers (Figure 13).
Figure 12. Electric Box
The key switch, shown in Figure 12, is located to the right of
the kill switch. The key switch should not work if the kill
switch is in the down “Down” position.
THE THROTTLE CONTROL CANNOT BE
USED TO STOP THE ENGINE.
Located in the center, these two levers control the direction
of travel for the drive tubes. They are independent of each
other, so one end can travel forward while the other travels
back. Using the levers in this way lets you steer the roller
screed.
In order for the drive tubes to move the screed, the “Screed
Operation” valve lever on the power unit must be engaged.
5.Strike Tube Control Lever (Figure 13)
On the far right is the strike tube cable control. Pushing the
lever to the center is the “Neutral Position”. Shifting the
lever either direction determines which way the strike tube
turns. The farther you push/pull the lever, the faster the
strike tubes turn.
6.Form Specifications
Refer to Appendix B for more information on the recommended
type of concrete form to be used.
The following steps are intended as a basic guide to machine start-up and operation. Following these procedures
will help preserve and maintain the life of this equipment.
⇒
Check oil levels in engine and hydraulic reservoir.
⇒
Check to make sure there is a full tank of fuel before
starting.
⇒
On the power unit, put the screed operation valve lever
in the “Screed Operation” position.

B.CLEANUP
Never allow any concrete to harden on the roller screed.
Immediately after use, wash any concrete off the screed.
Be careful not to spray water on the engine while it is still
hot.
To operate the pressure washer, attach a garden hose to the
pump and turn on the water. Next plug in the quick connect
hoses from the pressure washer to the power unit, adjust
the three way valve on the power unit as indicated by the
decal to the “Pressure Washer” position.
“Clean out” plates for the ends of the center strike tubes
(8’and 16’ tubes) should be removed and the ends cleaned
after each use.
Back off the 1-5/8 nut and jam nut on the outside strike
tubes next to the outer plate. Slide the strike tube away
from the middle bracket and clean the ends.
The solid scraper bars that prevent build-up on the drive
tubes should be removed and cleaned as well as the strike
tube wipers mounted in front of the 5 foot sections.
⇒
Once the engine is warm, put the toggle switch on throttle
control to the “High” position to begin operation.
Lubricate all grease zerks after cleaning the machine
while the chain guards are off, including bearings on the
middle brackets which hold the splined shafts.

WRS-5200 — MAINTENANCE AND ADJUSTMENT PROCEDURES
WARNING!
DO NOT AT ANY TIME MAKE ADJUSTMENTS TO THE ROLLER SCREED WITHOUT STOPPING THE ENGINE AND DISCONNECTING THE SPARK PLUG WIRE.
A.ADJUSTING STRIKE TUBE HEIGHT
Strike tube height is adjusted by raising or lowering the height
of the drive tubes. Figure 14 illustrates this. The chain idler
will also need adjusting in the same direction of travel as the
drive tubes. Loosen the two bolts which hold each drive
tube bearing and adjust the ¾” bolt to desired height. Tighten
the bearing bolts and chain idle adjustment when finished.
Adjust the strike tube so it is just clearing the concrete form.
B.CROWN ADJUSTMENT
To adjust the crown, pull the 3/8” safety snap pin and adjust
the screw with the wrench provided. Shown in Figure 15.
Figure 14. Strike Tube Adjustment
Figure 15. Crown and Camber Adjustment
C.CAMBER ADJUSTMENT
To modify the camber in the screed, adjust the turnbuckle
which is shown in Figure 15. Loosen the two jam nuts and
adjust the screw with the wrenches provided. A plum line
stretched along the front of the machine will help to adjust
straightness to.
Should strike tubes begin turning unevenly, contact your local Multiquip representative for information on strike tube
straightening procedures.
To determine if a strike tube is turning uneven, place a 2 x 4
stud on the ground in the center of the strike tube as it sits
on the machine. Slide it close to the strike tube. Take the
strike tube motor off the end. Spin the strike tube by hand. If
a gap of over 1/8 inch shows up, contact your representative.
E.AUXILIARY HUB
An auxiliary hub, shown in Figure 16, for use with different
strike tubes is provided. Using the hub provides additional
combinations of roller screed lengths. Two ½ x 2-1/4 bolts
are provided for the purpose of bolting the hub to the strike
tube end.
Wiper bars should be adjusted to approximately 1/8” distance from the strike tube. The turnbuckle in the top pipe of
the 5’ section is also an adjustment for the wiper bar. This
adjustment can be used when the end of the wiper bar is too
close to the strike tube. IMPORTANT: Never let anything
rub grooves into the strike tube( i.e. wiper bars, concrete
forms, bolts, etc.) because those grooves in the strike tube
will be transferred into the concrete.
H.STRIKE TUBE ADJUSTMENT NUT
The strike tube adjustment nut, shown in Figure 8, should
be adjusted so the inner edge of the strike tube next to the
middle bracket is spaced at about 1/16 to 1/8”. Note: The
strike tube will bottom out on the splined shaft when 1/16” is
left and further adjustment will bend the outer plate.
I.SPLINED SHAFT SET SCREWS
Each roller screed comes with two middle brackets as shown
in Figure 9. Bearings mounted on the middle bracket hold
the splined shaft. The set screws in the bearings should be
checked for tightness occasionally.
J.REVERSING END CASTER BRACKETS
Figure 17 illustrates how end caster brackets can be reversed. This allows the roller screed to fit into areas close to
walls and columns.
Figure 16. Auxiliary Hub
F.CHANGING THE HYDRAULIC FILTER
Usually the hydraulic filter and oil will be changed at the
same time. If not, creating a back suction on the hydraulic
tank will stop the flow of hydraulic oil when changing the
filters.
G.SCRAPER AND WIPER BAR ADJUSTMENT
Scraper bars should be adjusted to approximately 1/8” distance from the drive tubes.
READ THE INSTRUCTION MANUAL COMPLETELY BEFORE ATTEMPTING MACHINE OPERATION!
The following steps are intended as a basic guide to help in the operation of this
equipment.
A. FAMILIARIZATION WITH EQUIPMENT
Take a walk around the machine. Take notice of all the major
components on the machine like the control handles, the
engine, the strike tubes and the truss sections. Look at the
machine construction. Check the fuel and hydraulic system. Look at the engine and find the oil dipstick. Check the
oil levels in the engine and hydraulic tank. Make sure the
machine has fuel enough for the planned operation.
While seated in the operator’s position, note the locations of
the controls. On the left is the electric box with four switches
which were described in the startup section of this manual.
Just above the electric box on the left is the speed control
lever for the drive tubes.
In the center are the levers of the stack valve which operate
the drive tubes forward and reverse on both ends and finally
on the right side is the lever for running the strike tubes. The
speed of the strike tubes depends on the how far you push/
pull the lever. The cable from this lever is attached to the
hydraulic pump lever on the power unit.
B. FIRST MACHINE OPERATION
Now, following the startup procedure found in the “Machine
Start-up and Operation” section of this manual, start the
engine and let it warm up. Remember that when warming up
an engine, let the engine idle. When the engine is warm, test
the kill switch. The engine should die and the key should not
crank the engine with the emergency kill switch down.
Restart the engine. Before operating the roller screed, check
for people around the machine. As a suggestion, imagine a
rectangle that envelopes the entire machine. Never let anyone into that rectangle while you are operating the machine.
Always be aware of your surroundings.
Practice running the roller screed in a straight line. As you
become comfortable maneuvering the roller screed, try turning off one side of the drive tubes and then the other. This
adjusts how parallel the screed moves with the forms, and
also allows you to steer around the columns.
C.CONCEPTS FOR USE OF ROLLER SCREED
The purpose of the roller screed is to strike off the surface of
the concrete at a predetermined grade. The quality of
screeding has a big effect on floor levelness and flatness.
This machine was designed to be able to go back and forth
on the forms, working the concrete to the desired grade.
The strike tube rotation should always push the concrete
forward into the areas that don’t have concrete yet.
Depending on the slump of the concrete, several passes
might be required for the right strike off grade. On the last
pass over the concrete, rotate the strike tube in the opposite
direction and go slowly forward. This leaves a thin layer
which can be easily bull floated.
A pressure washer is available as an option with this machine. Figure 18 shows the components that come with this option.
This is a hydraulic-motor driven pump pressure washer which is connected to the power unit with quick connect fittings.
The pressure washer runs at 1500 psi and comes complete with a 50 foot pressure wash hose, trigger gun with insulated
wand and a turbo nozzle.
The Whiteman WRS-5200 roller screed provides all of the
benefits of labor savings, high productivity and enhanced
floor flatness/levelness qualities. To order to maximize these
benefits, care must be taken to insure a successful application. :Inadequate substrate and form support can lead to
form failure causing unnecessary job delays, and expenses
while contributing to poor floor flatness and floor levelness
ratings. The intent of these specifications is to establish
minimum guidelines to help the contractor choose the most
economical and effective form work/support system to fit
any job site needs.
It is recommended that at least the day prior to the concrete
pour, a dry run be accomplished to test the load capacity of
the forms and substrate. Proper job planning is essential to
a successful application.
The WRS-5200 weighs approximately 4000 .lbs (at 52 feet
of screed) approx. 2000 lbs. per side. Any screed support
(forms, rails, rail supports and substrate) must withstan0a
2s0s.0 lb. “point load” at a 2:1 safety factor.
WOOD FORMS-
Wood forms are NOT
Because of the concentrated bearing loads by the screed,
wood is not a good support material. Nominal 2x (1-1/2’7
No.2 Douglas fir is calculated to support a maximum of 1000
lb. The grain could crush and splinter causing level variations and potential failure. 4x (3-1/2") lumber for edge form
should be acceptable.
SCREED RAILS AND SUPPORT-
Screed rails (Figure 19) and supports, independent of slab
edge forming are a preferred method. Due to strength, deflection and traction considerations, 2.5" x 2.5" x 875 (3/16")
wall structural steel tubing with adjustable supports spaced
as shown in the attached drawings. Standard deflection with
a 3/16" wall thickness for the above configuration is 1/6" in 4
ft. Refer to standard material charts for other configurations.
STEEL FORMS-
a
preferred method of screed support.
SUBGRADE/DECK FORMS-
Subgrade must be sound enough to support slab edge forms
and bracing as well as the load imposed by the screed and
its supports. Potential deflection, as in the case with metal
and plywood decks, should be considered when determining
brace and support spacing. Soil subgrades must be well
compacted and must be able to support bearing pressures
greater, than or equal to those imposed by the screed supports and the slab forming. For proper bearing support, shims
should be used to adequately distribute loads where grade
is not level or is soft. Use standard AC:[ concrete form pressures when calculating lateral loads on slab edge forms
Paving forms with 90° lip-edge at bottom with stake pockets
is preferred. If soft or unleveled subgrade is encountered, a
2x bearing pad and/or shims should be used under the steel
forms for additional bearing support. Depending on slab thickness and subgrade, forms may require diagonal bracing.
