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. Made 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 as shown,
making sure that blade
is positioned on the
“front side” of the base
extrusion.
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.

MACHINE ADJUSTMENTS
HANDLES
Your Shockwave™ screed has handles that can be
adjusted for a customized fit.
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.
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
ADJUSTABLE
;OLWP[JOVM[OLNYPWZJHUILHKQ\Z[LKá]LY[PJHSS`
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.
CAUTION !!
Always make sure engine is stopped with switch in "OFF"
position before making adjustments.
