1. How to connect exhaust pipes
To connect the exhaust pipes, fit the male end into the female end and clamp with pipe stopper A to prevent
slipping. The exhaust pipe can be telescoped to the required length; do not cut it.
2. How to connect air intake hose
Screw hose joint half of its length onto the air intake hose, then screw another air intake hose into the joint.
The hose can be cut to the required length.
IMPORTANT: The PVC air line is longer than the exhaust line and may need to be cut to size. Be sure,
however, to thoroughly deburr all rough edges.
