Fig. 16 Attaching motor/blower cleaning and storage covers
2. Battery:
• While still on the blower, wipe the housing of the battery pack with a soft cloth dipped in mild
cleaning solution. Then wipe with a soft cloth dipped in clean water. Wipe dry.
• Remove battery and wipe down top of battery pack, if needed, with a soft dry cloth. Avoid
contact with the blower/charger connection pads; if they become damp, allow to dry before
reinstalling on blower or charger.
• If needed, the battery strap included with the 3M™ Cleaning and Storage Kit TR-653 can be
used to protect the pads during cleaning. With the strap in place, the battery can now be rinsed
under running water, immersed, or put in a respirator washer for further cleaning.
3. Breathing tube:
• Detach breathing tube with unit upside down (Fig. 12).
• Clean the connection sites on the breathing tube with the water and detergent solution. The
breathing tube can be immersed in water for cleaning if required. The inside of the tube must be
completely dried prior to use or storage.
• Air dry, or dry by connecting to the motor/blower unit and use it to force air through the tube until
dry. Orient tube to prevent water from running into blower.
• Optional plastic breathing tube covers (BT-922) may also be used to facilitate cleaning.
4. Belt/backpack:
• Remove the belt from the motor/blower by lifting the bottom of the belt over the belt locking
tabs and sliding the belt down. The 3M™ Easy Clean Belt TR-627 is made of a non-porous and
closed-cell material and can be wiped down or submersed in a soapy water solution. The 3M™
High Durability Belt TR-626 is made of leather leads with a rubber hip belt.
• To remove backpack from motor/blower, while lifting locking tab near the bottom of the blower
and in the key hole, slide the backpack towards the bottom of the blower to release. The 3M™
Easy Clean Backpack TR-927 is made of a non-porous material and can be wiped down using
or submersed in a soapy water solution. For additional chemical cleaners, please review 3M
Inspection, Cleaning, and Storage Procedures for TR-600 technical data bulletin for guidance.
BPK-HD cleaning and storage instruction are located in the User Instructions packaged with the
product.
• The leather leads can be cleaned with a leather cleaner. Wipe or rinse all belts and backpacks
thoroughly and dry completely before next use.
5. Filter/cartridge:
• Remove the filter cover and inspect the filter/cartridge (and prefilter/spark arrestor if used).
Replace filter/cartridge if excessively dirty, wet or damaged.
• Do not attempt to clean the inside of the filter/cartridge housing or the filter/cartridge media
itself. Do not clean with compressed or pressurized air. Doing so will damage the media. The
exterior of the filter/cartridge can be gently wiped down with a dry or damp cloth to remove
excess dirt and debris.
• The prefilter (3M™ Prefilter TR-6600) cannot be cleaned. Replace if excessively dirty or damaged.
• The spark arrestor (3M™ Spark Arrestor TR-662) can be cleaned using a water and detergent
solution. Completely dry the spark arrestor with a clean cloth or air dry. If the spark arrestor
cannot be cleaned or is damaged, replace with a new spark arrestor.
NOTE: To minimize material falling onto the motor/blower, remove the filter/cartridge while it is facing
downward (Fig. 6).
Storage
Clean the system prior to storing. Store in a clean/dry environment not exposed to contaminant
dusts, gasses or vapors. Filters/cartridges may be stored attached to the blower. Do not hang blower
or headtop by the breathing tube, or hang the blower from the headtop. The system must be fully
inspected prior to next use. For prolonged storage, the motor must be run for 5 minutes annually to
ensure proper lubrication and operation.
See "Specifications" section of these User Instructions for information on suggested storage
temperatures. Humidity and ambient contaminants may diffuse into chemical cartridges once they are
removed from their original packaging, which may reduce service life. Storing chemical cartridges in
a clean airtight container, attached to or removed from the blower body, may help maintain remaining
