Install Guides
Note: If you have a right angle drill, you can
drill holes in the blower housing from
the inside, using a guide strap as a
template, and do not need to remove
the housing; skip to step 2. If you
have a regular drill you must complete
step 1 to remove the blower housing
before drilling holes.
1. Remove the blower housing, as follows:
A. Remove (4) locknuts from the front of the
blower housing.
B. Remove (2) 5” capscrews from the upper
part of the housing.
C. Remove (1) 3/8 x 3/4” capscrew from the
inside of blower chute and slide the chute
up and away from lower blower housing.
D. With the blower chute raised, pull the front
blower housing forward and free from the
rest of the housing.
2. Mark, center punch, and drill (3) 9/32” (7.5 mm)
holes in the blower housing, as shown, for
mounting the guides (Fig. 2).
Note: To ensure that the holes are aligned in
the correct position, it is helpful to
position a guide strap on the blower
housing with upset toward blower
opening and against flared flange
(Fig. 3) when marking the holes.

3. Place (3) guide straps outside the blower
opening with the upset toward blower opening
and against the flared flange (Fig. 3).
IMPORTANT: The guide straps should be
pulled snug against the flared flange of the
blower housing.
4. Secure each strap to the blower housing with a
1/4–20 x 3/4” (19 mm) bolt, through from the
inside of the housing, and a 1/4-20 flange
locknut (Fig. 3).
