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
s
Blade sinking below wet pads
s
Ripple or “wake marks” following the blade
s
Concrete easily sliding underneath form boards causing dips
s
along the form edge
Always remember,
the less vibration the better
. Use only
enough vibration to be able to comfortably pull screed back-
wards, leaving a smooth, level surface.
ALWAYS
Always stop engine between loads of concrete
s
Always screed while walking backwards
s
Always clearly mark and be aware of all grade pins,
s
form stakes or other trip hazards
Always follow all safety warnings and labels of the
s
engine manufacturer
Always read and understand the owners manual of
s
the engine manufacturer
Always wear approved hearing, eye and breathing protection
s
Always use form oil to coat blade or other parts susceptible
s
to concrete build up (avoiding electrical connections) before
each use
Always properly secure screed before transporting
s
Always follow recommended maintenance schedules
s
Always make sure all connections and fasteners are tight
s
before every use
Always always make sure engine is in "OFF" position when
s
servicing or not in use
Always use in a well ventilated area
s
Always keep Shockwave™ and engine manual handy
s
on the job site
Always replace parts as they become damaged or worn
s
NEVER
Never operate screed without all parts and safety
s
covers correctly attached
Never allow children to operate
s
Never operate under the influence of drugs or alcohol
s
Never use screed for anything other than its
s
intended purpose
Never set eccentric weights to where excessive vibration
s
occurs at low RPM (weights too far open)
Never set eccentric weights to where it takes excessive
s
RPM to make weights vibrate (weights too far closed)
Never allow engine to run unattended or idle on
s
top of wet concrete
Never place concrete higher than the leading
s
“curl edge” of the blade
Never fill gas tank while engine is running
s
Never start engine near spilt fuel
s
Never fill gas tank, operate, or service screed
s
near open flame
Never use parts or blades from other manufacturers
s
Never service a hot engine
s
Never operate without proper training
s
Never spray water or other liquid on a hot engine
