Note: In order to start the Auto Cycle the feed ring MUST be rotated off the stop position.
Lower Adjust Knob:
The lower limit is attached to a threaded shaft. This threaded shaft supports the switch that signals the
stroke to go back up. Pull the rocker arm down to a point where the hone stones have the proper
extension through the bottom of the cylinder bore. Loosen the lock knob, allowing the adjustment knob to
be turned. Turn the adjustment knob to its correct position and lock down firmly with lock knob to avoid
slippage.
When the machine is running the arm will go down until it hits the lower limit, reverse and go back up.
Upper Limit Lever:
The upper limit lever is on the right side of the rocker arm. Tightening this lever clamps the rocker arm
linkage to the stroke cylinder. The rocker arm is brought to the position where the hone stones are at the
proper upper travel limit. The upper limit lever is then tightened and the rocker arm stays in position.
Note: The lower Adjustment Knob must be set first.
When stroke is started, the stroke cylinder pulls the rocker arm up and down.
