6. Grasp the starter grip (Figure 26) and slowly pull it
out. The resistance becomes the hardest at a certain
position, corresponding to the compression point. Pull
the starter grip briskly and smoothly for starting.

7. Run the engine for several minutes and check for fuel
leaks, and noises that would associate with a loose
guard or cover.
8. After the engine has warmed, place the choke lever
in the open position (Figure 27) before operating the
screed.

OperatiOn
engine driven Screed
1. Engage or turn winch handles simultaneously to keep
screed even.
2. If the concrete is not being added at the appropriate
rate, slow down the screed to compensate.
3. The speed that the screed should be operated at is
determined by the slump of the concrete. Pay close
attention to the aggregates, slump, and concrete
modifying agents so that you can compensate for them.
4. After completion of the pours, make sure to clean the
screed immediately to prevent concrete from curing on
the drive shaft and bearings.
STopping THe engine
1. Place the throttle lever (Figure 24) in slow position, and
listen for the engine speed to decrease.
2. Let engine idle for 3-5 minutes.
3. Place the Engine ON/OFF switch (Figure 25) in the
" OFF" position.
4. Place the fuel valve lever (Figure 21) in the " OFF"
position.
NOTICE
never let the concrete build up on the front blade.
This causes the screed to be stressed and is strenuous
on the operators controlling the manual winches. The
concrete should not go above the bolts attaching the
blades. If this happens, stop the screed and let the
vibration do its job.
NOTICE
reminder: DO NOT over-vibrate the concrete.
cauTion
never stop the engine suddenly while working at
high speeds.
