WARNING

Do not at any time make any adjustments without first stopping the engine, disconnecting spark plug wire and grounding it against the engine. Always wear safety glasses during operation or while performing any adjustments or repairs.

Wedge Assembly Adjustment

As normal wear occurs and there is excessive “play” between the wedge and beam, adjust the bolts on the side of the wedge assembly to eliminate excess space between the wedge and the beam.

1.Loosen the jam nuts on the two adjustment bolts on the side of the wedge. See Figure 5-1.

2.Turn the adjustment bolts in until snug and then back them off slowly (approximately 1.5 turns) until the wedge assembly will slide on the beam.

3.Re-tighten the jam nuts securely against the side of the wedge to secure the adjustment bolts in this position.
