INTRODUCTION

Oil Level Check
Page 5February 2016 SCR-UM-00364-EN-02
The Screed King power screed is designed and manufactured to meet the needs of a
discriminating buyer for the efficient finishing of concrete�
The directions left, right, front and rear as mentioned throughout this manual, are as seen
from behind the machine, standing between the handles�
OIL LEVEL CHECK
OIL FILLER CAP/DIPSTICK
LOWER LIMIT
OIL FILL HOLE
(bottom edge)
Figure 1: Oil filler hole location
It is important that the engine oil level be maintained at the correct level� High or low oil
levels cause permanent damage to the engine requiring replacement� To check the oil level:
1� Place the screed board on a at level surface to perform an oil level check�
2� Carefully unscrew the oil ller cap/dipstick and wipe it clean�
3� Insert and remove the oil ller cap/dipstick without screwing it into the oil reservoir
neck, to check the oil level shown on the dipstick�
4� If the oil level is near or below the lower limit mark on the dipstick, ll the reservoir to
the bottom edge of the oil ll hole with the recommended oil� See the Honda engine
owners manual for more information�
5� To avoid overlling or underlling, make sure the engine is in a level position when
adding oil�
6� Reinstall the oil ller cap/dipstick and tighten securely�
MPORTANTI
Running the engine with a low oil level can cause engine damage. This type of damage is not
covered by the warranty.

Power Unit Assembly
Page 6 February 2016SCR-UM-00364-EN-02
POWER UNIT ASSEMBLY
The tools required for assembly are:
• (1) 7/16 in� (11 mm) open or box end wrench
• (1) 11/16 in� (17 mm) open or box end wrench
• (1) #2 Flathead screwdriver
• (1) Slip joint pliers
Figure 2: Required tools
Handle Assembly
1� Remove the handles from their shipping position by removing the two top 7/16 in�
(11 mm) nuts, the quick release levers and the top handle cap�
Figure 3: Handle plate positioning
2� Insert the bottom of the handles into the back of the handle plate and replace the top
handle cap over the handle�
3� Thread on the two top 7/16 in� (11 mm) nuts�
4� Install the quick release levers on the top of each bracket� Placing the black hand levers
in the lower position will result in handlebar movement�
5� With the lever in the open position, thread it through the cap, handle plate and quick
release nut� Continue threading until tight�
6� When hand-tight, place the handles at the appropriate height and close the lever�

Throttle Assembly
Figure 6: Throttle assembly location
1� Place the throttle lever on the left handle just below the hand grip�
2� Position the lever so it clears the handle guard in all positions�
3� Place the lever ring clamp around the handle bar and tighten with a athead
screwdriver and adjustable pliers�
4� Use the zip ties provided to keep the throttle cable tight to the handle bars�
5� Check to make sure the cable stop for the throttle adjustment cable is fully seated into
the throttle adjustment linkage on the carburetor� Make sure the metal cable stop is
completely inside the throttle adjustment linkage, as shown below�
Correct
Figure 7: Throttle assembly detail
a� If the cable stop is not fully seated, loosen the throttle control adjustment
screw and grab the end of the adjustment cable with the slip joint pliers�
6� Pull gently on the cable until the cable stop is completely within the throttle
adjustment linkage�

7� With the throttle lever pushed to the far right, hold the throttle adjustment cable so
there is no slack and then tighten the throttle control adjustment screw to clamp the
cable in place�
Figure 8: Throttle assembly connection
Weight Adjustment
The eccentric weight on the power head is factory set to its maximum force� This setting
settles concrete with a 2…8 in� (50…203 mm) slump� The weight needs to be adjusted only
when the screed is going to be used on unusually high slump concrete�
To change the force of vibration, adjust the position of the eccentric weight as follows:
1� Using a 1/4 in� (6 mm) Allen key, loosen the set screw on the thicker weight�
2� While holding the thick weight stationary with the Allen key, turn the thin weight by
hand to the required position�
Turning the thin weight set screw clockwise decreases the force to zero when the flat edge
of the thin weight is parallel to the flat edge of the thick weight�
Figure 9: Least vibration Figure 10: Maximum vibration (factory setting)
Turning the thin weight counter clockwise increases the force of vibration until the flat
edge of the thin weight is flush with the opposite edge of the thick weight�
Figure 11: 3/4 vibration Figure 12: 1/2 vibration

Throttle Cable Adjustment
The throttle cable comes pre-assembled for your convenience� Over time you may notice
that it takes more clicks on the throttle to reach the optimum RPM level than when you first
ran the screed� This is normal as the throttle cable stretches over time�
Figure 13: Throttle cable adjustment
To adjust your throttle cable to compensate for this stretching:
1� Locate the barrel adjuster where the cable runs into the underside of the engine�
2� Turn the barrel adjuster counterclockwise with an 8 mm wrench�
3� Tighten the locknut to hold it in the desired position�
Attaching the Screed Bar
1� Locate the threaded studs on the screed bar and loosen the locking handles�
2� Slide the power head of the screed over the threaded studs�
3� Fasten the power head to the bar using the locking handles and washers provided,
as shown below� The washer and lock-washer should contact the silver handles when
installing the power unit�
Figure 14: Attaching the screed bar
4� Make sure to fully tighten the bolts so they do not come loose during use�
