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
The pitch of the grips can be adjusted 360˚ vertically
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 .
