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

ASSEMBLY INSTRUCTIONS
INSTALLING THROTTLE CABLE:
Step 1 – Remove carburetor cover by pressing clips.
B
A
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 3 – Fasten the throttle cable as shown. Make sure
there is a nut on each side of plastic fitting. Made sure the
cable does not work itself out of the plastic fitting
while tightening.

Step 4 – Attach the throttle lever to the “T” grip handle,
as shown above.

ASSEMBLY INSTRUCTIONS
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.
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 as shown,
making sure that blade
is positioned on the
“front side” of the base
extrusion.
Make sure bolts
!
are tight before
each use.

MACHINE ADJUSTMENTS
HANDLES
Your Shockwave™ screed has handles that can be
adjusted for a customized fit.
ADJUSTABLE
The height of the handle can be adjusted right
below the motor
The grips can also be moved to accommodate wider
and narrower grips, as well as flipped to the inside of the
machine for an even narrower grip.
CAUTION
Always make sure engine is stopped with switch in "OFF"
position before making adjustments.
ECCENTRIC WEIGHTS
The factory weight setting 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 screwdriver 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 pitch of the grips can be adjusted 360˚ vertically

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.

CAUTION
Your Shockwave ships with a
pre-measured bottle of oil (3.5 oz).
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 uses
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
capacity. 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.

CLOSED
OPEN
2
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.

OPERATING ON WET CONCRETE
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 RMP 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 RMP 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.
