Ensure that there is still enough tension on the cable and
spring to prevent parts from coming unhooked during
operation. If the tendency for the blades to rotate when the
Dyna-Clutch lever is disengaged cannot be adjusted out of the
system without taking all tension off of the cable and spring,
carefully inspect the drive belt and Dyna-Clutch lever system
for wear or damage. Ensure that all parts are operating freely.
If the Dyna-Clutch lever does not stop the blades, see an
Authorized Service Dealer.
Testing the Dyna-Clutch Lever
Adjustment
Ensure that the testing of the Dyna-Clutch lever is done is
a clear and open area.
1. Move the Dyna-Clutch lever to the Stop position.
2. Start the trowel.
3. Turn off the fuel valve.
4. Hold onto the handle and engage the Dyna-Clutch
lever.
5. Let go of the handle.
The Dyna-Clutch lever should switch to the Stop
position within 1 rotation. If it does not, keep clear of
the area and wait for the machine to run out of fuel.
Bring the machine to an authorized service location.
Adjusting the Blades
Adjust the blades to remove excessive shaking of the machine.
1. Disconnect the spark plug wire and move the
Dyna-Clutch lever to the Stop position.
2. Place 3 or 4 blocks of equal height under the stationary
blade guard (outer ring) to raise the blades off of the
floor.
Note: Ensure that the blocks are clear of the blades
so that the blades can be rotated without touching the
blocks.
