Note & Caution on Installation
If you will install the ring muffler to aircrafts already completed, there are cases where modification for around firewall in the cowling may be required.
Be sure to read the setting manual carefully before installation.
Apply lubricant oil to the thread of the nuts so that all threads can be turned smoothly before inserting the 3 nuts of the ring muffler into each cylinder.
Tighten up each nut of the ring muffler evenly and gradually by a spanner after turning approx.3 turns of each nut by fingers.
If you forcibly insert and tighten them, the cylinders will break.
