• The drum key can be found in the pad set package.
• Avoid over-tightening the bolts. If you hear a creaking sound in the wooden body, loosen the bolts slightly.
• The head is properly tightened when the surface is smooth, with no wrinkles, yet sinks a little when you press
the center.
• Unlike acoustic drums, electronic drums have the same tone even when the head tension is changed. Adjusting
the head tension is necessary to adjust the feel and prevent malfunction.
The patch is made from consumable material, and may need to replaced when it becomes wrinkled, torn, or peeled. This
product contains two spare patches, if they are used or missing, contact your dealer or qualified Yamaha service personnel.
Patching the contact area with the beater can reduce wear on the head and beater.
Adjusting the Head Tension
• The drum key bolts for tightening the head can be loosened while using. Each time before you play, adjust the head
tension to prevent rattling and loosening of the head.
To adjust the head tension, tighten or loosen the six drum key bolts on the outside of the head in the order shown in
the figure below. Make sure to tighten or loosen the drum key bolts evenly. If you tighten or loosen only one, the head
tension will not be even.
• Do not use a long handle drum key (such as a high-torque drum key or high-tension drum key) to tighten the head.
Over-tightening can damage your drum.
