ASSEMBLY INSTRUCTIONS
Assembly is easy, following these steps:
INSTALLING HANDLE BARS AND KICKSTAND:
Step 1 – Remove the 4 hex screws (A) that hold down the two
handle mounting blocks.
Step 2 – Slide kickstand arm onto kickstand end and fasten
with nut & bolt (B) as shown
Step 4 – Making sure all mounting block and frame holes are
aligned, insert hex screws and tighten with 7/16" wrench or
socket.
Step 3 – Place handle bars into mounting blocks, making sure
handle bars are centered evenly across the mounting blocks.

INSTALLING THROTTLE CABLE:
Step 1 – Remove carburetor cover by pressing clips.
Step 4 – Attach the throttle lever to the handle, as shown
above.
Step 3 – Fasten the throttle cable as shown. Make sure
there is a nut on each side of plastic fitting. Make sure the
cable does not work itself out of the plastic fitting
while tightening.
Step 2 – The throttle has a rotating silver peg (A) with a slot
on one side of it. One end of the throttle cable has a metal
barrel (B) that fits into this slot. Insert barrel into the slot so
when the throttle cable is pulled, it will pull the throttle open
(toward the base plate of the screed).

Step 7 – Secure throttle cable using clips,
as shown above.
Step 6 - Once cable is through throttle lever, return the
lever to the “idle” position shown above. Using pliers, pull
all extra slack out of the cable, making sure you are not
actually opening the throttle at the carburetor. Once all
slack is removed, tighten locking screw.
Note – the plastic housing of the throttle cable will fit up into
the throttle cable housing.
ATTACHING BLADE
Attach blade making
sure that it is posi-
tioned on the “back
side” of the base
extrusion. Be sure to
insert the plastic
spacer between the
blade and mounting
plate
Make sure bolts
are tight before
each use.
Step 5 – Thread the exposed metal end of the throttle cable
into the throttle lever. The lever will need to be “opened” to
expose the hole it fits into. Back out the set screw to allow
the cable to pass through.
ASSEMBLY INSTRUCTIONS
Plastic Spacer - insert between blade and mounting plate

MACHINE ADJUSTMENTS
HANDLE
Your screed handle can be adjusted for a customized fit.
ECCENTRIC WEIGHTS
The factory weight set-
ting will provide sufficient
board vibration for most
jobs. For jobs where low
slump or dry concrete is
being poured, the weight
can easily be adjusted to
allow for more vibration at
lower RPM.
Using a slotted screw-
driver remove the
eccentric cover. Using a
7/16" socket, loosen the
eccentric weight tightening
bolt (A). You will need
to wedge a screwdriver
against the weight to keep
it from turning while
loosening bolt.
ADJUSTABLE
The height of the handle can be adjusted right
below the motor
DECREASE
INCREASE
Increase vibration, increase the gap between the weights
by spreading them apart.
Decrease vibration, decrease the gap between the
weights. If imbalance is increased then use less engine
RPM. Note: Always check and retighten the eccentric
weights every 10 hours of use.
WARNING !!
Always make sure engine is stopped with switch in "OFF"
position before making adjustments.

SETTING ELEVATION OF SLAB
• Use grade pins (A) to set height of slab
in the middle of the pour.
• Chalk line or expansion joint sets
elevation around walls.
• Form boards set elevation where
there are no walls.
MAKING WET PADS
1. Using hand float, make wet pads around all grade
pins (A).
Note: Make sure all wet pad distances
are shorter than the length of board
being used.
2. Use board to stretch from wet pad to wet pad form-
ing rows (B).
3. Once rows are formed, run screed board off of the
two rows leveling the previously untouched con-
crete (C) in between.
NOTE: Height of concrete in area (C)
must be slightly higher than wet
pad rows (B) prior to striking off.
Once floated, wet pads (B) and concrete (C) will all be the
same height

Length of board should overlap form boards on both
sides of the pour
Keep bottom of blade as flat as possible while striking
off of forms
To ensure the longest possible board life, use the
lowest possible vibration setting in relationship to the
slump of concrete being used.
HOW TO SCREED FORM TO FORM

TRAILING EDGE
An elevated trailing edge may provide an area
for concrete to build up resulting in a slab
elevation that is too high

LEADING EDGE
An elevated leading edge can trap rocks

!!
Your screed ships with a

Do not at anytime have more than 3.5 oz. of
oil in the engine. Too much oil will foul out
the spark plug resulting in an engine that is
hard to start and keep running.

HOW TO OPERATE
FUEL AND OIL
Make sure gas tank has plenty of 86 octane or
higher gasoline. Your 4 stroke Honda engine used
straight gasoline, NEVER USE A GAS/OIL MIX.
Empty entire bottle of provided Honda engine oil
into crank case. 3.5 oz. is the maximum oil capac-
ity. NEVER OVERFILL.
STARTING
1. On a cold engine, move choke lever to CLOSED
position. To restart a warm engine leave choke in
OPEN position
2. Press priming bulb repeatedly until fuel can be
seen in the clear-plastic fuel-return tube
3. Press On/Off Switch to the On Position.
4. Pull the starter grip lightly until you feel resistance,
then pull briskly. Repeat until engine starts.
5. If the choke lever was moved to the CLOSED
position to start the engine, gradually move it to
the OPEN position as the engine warms up.
RESTARTING A WARM ENGINE
1. Leave the choke lever in the OPEN position.
2. If there is no fuel in the clear-plastic fuel-return
tube, press priming bulb repeatedly
until fuel can be seen in the tube.
3. Press On/Off Switch to the On Position
4. Pull the starter grip lightly until you feel resistance,
then pull briskly. Repeat until engine starts.

Once the engine is warm and running by itself with the choke OPEN you can begin screeding concrete.
For specific instructions on Wet Screeding and Form to Form screeding please see pages 10 and 11.
1. Begin by placing concrete within your forms slightly higher than the forms themselves.
2. Place screed on top of concrete and start engine.
3. Increase engine RPM until the clutch engages causing the screed to vibrate.
4. Walking backwards, begin screeding concrete (see page 10 for Wet Screeding or Page 11 for Form to Form screeding).
5. Your throttle lever does not require constant contact, but you can adjust RPM and vibration to accommodate wet or dry concrete.
Dry or low slump concrete may require more vibration to level and screed
6. Continue moving backwards while keeping concrete placed in front of the blade. The roll back feature of the blade will keep help
keep concrete from sliding over the blade. Concrete placed too high may slide over the board! This could make the screed too
hard to pull and result in a slab that is out of level.
DO NOT OVER VIBRATE CONCRETE!
The following are signs of too much vibration:
• Excessive concrete splatter
• Blade sinking below wet pads
• Ripple or “wake marks” following the blade
• Concrete easily sliding underneath form boards causing dips along the form edge
Always remember, the less vibration the better. Use only enough vibration to be able to comfortably pull screed backwards, leaving
a smooth, level surface.
