To attach the spring, pull the triangle - with the spring attached - over and into the notch in the cam roller.

Insert the beater shaft into the beater link and tighten the key bolt with your drum key. For now, set the beater so that about 1/4" of the beater shaft is visible at the bottom of the beater link. By moving the beater up or down in minute increments, you can "fine-tune" the feel of the pedal to your preference.
 

Pedal Attachment

If your bass drum has metal hoops, adhere the self-stick rubber pad into the channel of the back hoop where the pedal attaches.
 

Lift the backside of the bass drum and slide the pedal onto the bass drum hoop. If necessary, loosen the T-bolt on the hoop clamp to widen the opening. Center the pedal so that it sits squarely on the floor. Tighten the hoop clamp securely.

Tighten clockwise to clamp the pedal to the bass drum hoop.

Spring Adjustment

Loosen the top lock nut (A) and adjust the spring tension nut (B) until the spring tension feels comfortable to you. Tighten nut (A) to keep this setting.
