Operating On Wet Concrete - Marshalltown SPEED STRIKER STRIKE45-L Manual Del Usuario

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 (see page 12 for Wet Screeding or Page 13 for Form to Form screeding).
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
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.
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.
