Belt
Select an approved belt appropriate for the work conditions. Install the belt by threading the end of the
belt through the retaining slots on the back side of the motor/blower (Fig. 8). Position the motor/blower
so it rests in the small of the back or other location around the waist. Tighten belt for a snug fi t. For
TR-325 (nylon web) and TR-327 (Easy Clean), multiple belts can be interconnected to provide the
wearer with a comfortable fi t. An optional belt extender (15-0099-06) is available for the TR-326
leather belt. If needed two leather belts could also be interconnected.
Three optional 3 bar belt slides are included. The slides can be placed on the belt on both sides of the
motor/blower to prevent the motor/blower from moving along the belt. The third slider can be used as
a keeper for extra belt length. Place the sliders on the belt so the rounded side is on the exterior of the
belt.

Removal of HE fi lter, prefi lter or spark arrestor
Ensure the unit is off. Do not replace the fi lter, prefi lter, or spark arrestor with the unit running. Repeat
step 2 in the previous section,
Installing the fi lter,
to access the HE fi lter and if using the prefi lter or
spark arrestor. Remove each by lifting out. Alternatively the user may wish to hold the PAPR motor
blower facing downward (cover towards the ground) during removal of the cover and fi lters. This will
help minimize the potential for contamination of the interior of the motor blower during cover and fi lter
removal.
Filter Notes:
o For long-term storage, remove the HE fi lter and seal in a closed container. 3M does
not recommend the HE fi lter be left in place on the motor/blower units long-term as
damage may occur to the fi lter seal.
