FIGURE 7-1. Releasing rain diverter from intake assembly
Slide the foam insulation down the tube to expose the filter.
Unthread the rain diverter from the filter. Place the rain diverter loosely in its
mounting hole to keep it from falling.
Unthread the filter from the orifice.
To avoid the risk of dropping the orifice, keep the orifice
attached to the tube.
The orifice usually does not need to be replaced as a result of
normal usage. However, if it becomes clogged, damaged, or lost,
it may be replaced with pn 29999.
Thread a new filter (pn 29998) onto the orifice.
