Testing the Dyna-Clutch Lever
Testing the Dyna-Clutch Operation
Ensure that the area is clear of any debris or bystanders
before beginning the testing procedures.
1. Start the trowel, engage the Dyna-Clutch lever, and run
the machine for a few moments.
2. Move the Dyna-Clutch lever to the Stop position.
3. Watch the blades for any sign of continued rotation.
If the blades do not stop, there is too much tension
on the cable and spring. Stop the engine and decrease
the amount of tension to allow the Dyna-Clutch lever
to disengage completely.
