Install and remove HE filter, prefilter, spark arrestor and cover
Install and remove the filter in non-hazardous locations only.
1. Inspect the HE filter to be installed:
• Filter is intact with no tears, cracks, distortion or other damage.
• The inner circular gasket is present and intact with no tears, cuts or distortions. Wipe the filter seal with a clean
cloth if necessary. Dispose of and replace filter if damage is noted or suspected. NOTE: The TR-3712N filter has
both an inner circular gasket (Fig. 6-6) and outer rectangular barrier (Fig. 6-5). The inner gasket is the primary
seal between the filter and blower. The outer barrier acts to keep dirt and debris from behind the filter.
2. Confirm the TR-300+ is powered off. Do not install or replace the filter, prefilter, or spark arrestor/prefilter
while the motor/blower is running.
3. Place the TR-371+ filter cover so it faces down.
4. (If required) insert the metal mesh spark arrestor/prefilter into the cover, ensuring the cutouts are aligned properly.
5. (If required) insert the foam prefilter, ensuring the cutouts are aligned properly (do not use in combination with the
spark arrestor).
6. Place the HE filter into the filter cover. Ensure that the HE filter label can be seen in the filter cover view window.
7. Place the hinge side of the filter/cover assembly into the motor/blower hinge (Fig. 5-1) and snap latch side into the
filter latch (Fig. 5-2).
8. Gently tug on filter/cover assembly to ensure proper attachment at both sides.

9. Removal of filter/cover assembly (perform in non-hazardous locations only):
• Turn the unit off. Do not remove or replace filter while the motor/blower is running.
• Hold the unit downwards so the back (belt side) faces you and the filter and cover face down to help minimize
the potential for contamination of the motor/blower inlet (Fig. 7).
• Press the blue filter latch. Pull the filter/cover assembly out and away from the motor/blower.
