INITIAL STEP
Alignment tool 40C1211
To ensure correct alignment of the assembly there
are 2 procedures that may be required:
Procedure 1
The 4 bolts holding the wave trap to the cavity need
to be loosened off sufficiently to allow movement of
the wave trap.
See figure 6 (see Alignment tool figure 8)
You must then slide the alignment tool onto the
motor shaft, keeping pressure on the rear of the tool
only and not applying any sideways pressure. At the
same time pushing on the bolts of the wave trap to
manipulate the trap into a position where the outer
diameter of the tool goes into the hole of the wave
trap.Once the tool is located, tighten up the 4 bolts
and remove the alignment tool.
If procedure 1 is successful go to step 11
Procedure 2
With both wave trap and hot air motor secure, you
must then slide the alignment tool onto the motor
shaft, keeping pressure on the rear of the tool only
and not applying any sideways pressure until it
bottoms out on the cavity face. You must then push
sideways and forward on the tool to allow the initial
step of the tool to go into the wave trap, making note
of which direction you had to push the tool for when
aligning the motor.
See figures 7(a) & 7(b) (see tool figure 8)
With the alignment tool in position, you must then
loosen the 4 nuts holding the fibre board that the
motor is mounted to.This will allow you to push the
board not the motor in the same direction as they
pushed the tool. This will then bring the motor into
alignment with the wave trap.
Note: If you are looking into the cavity and had to
push the tool to the right, when looking at the motor
