ASSEMBLY INSTRUCTIONS
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 ⁄"
wrench or socket.
Step 3 – Place handle bars into mounting blocks, making
sure handle bars are centered evenly across the
mounting blocks.
INSTALLING HANDLE BARS AND KICKSTAND
ATTACHING BLADE
Attach blade as shown, making sure the blade is
positioned on the “back side” of the base casting with
blade spacers (A) on both sides of the blade.
Make sure bolts are tight before each use.

INSTALLING THROTTLE CABLE
Step 1 – Remove carburetor cover by pressing clips.
Step 4 – Attach the throttle lever to the “T” grip 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.
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.

HOW TO WET SCREED
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 blade being used.
2. Use blade to stretch from wet pad to wet pad
forming rows (B).
3. Once rows are formed, run screed blade off of the two
rows leveling the previously untouched concrete (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.

HOW TO SCREED FORM TO FORM
Length of blade 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 blade life, use the
lowest possible vibration setting in relationship to the
slump of concrete being used.

TRAILING EDGE

LEADING EDGE
KEEP SCREED BLADE FLAT
Form Board
An elevated trailing edge may provide an area for
concrete to build up resulting in a slab elevation that
is too high.
An elevated leading edge can trap rocks between the
blade and forms resulting in a slab elevation that is too
high.

HOW TO OPERATE
FUEL AND OIL

Your 4 stroke Honda engine uses straight gasoline. NEVER
USE A GAS/OIL MIX. Empty entire bottle of provided Honda
engine oil into crank case. The maximum oil capacity is 3.5 oz.
Always lay screed down on roll cage as shown when filling gas
and oil or checking oil. 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 12 and 13.
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.
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
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.
OPERATING ON WET CONCRETE
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.
