WARNING
Safety Precautions
Ash produced by diesel particulate filters has been declared a hazardous waste in some areas of the
United States. Follow federal, state, and local procedures for the handling and disposal of ash.
To prevent personal injury when using the Diesel Particulate Filter Cleaner :
•Study, understand, and follow all instructions before operating this device. If the operator cannot
read these instructions, operating instructions and safety precautions must be read and discussed
in the operator’s native language.
•Wear eye protection that meets OSHA standards. If there is eye contact with the ash, flush eyes
with cold water for 30 minutes.
•Set up the DPF Cleaner in an area where there is adequate ventilation. Wear a dust mask (rated
N95) to avoid breathing the ash. If dust is seen escaping from the machine during a cleaning
procedure, immediately stop the DPF Cleaner and check all connections.
•Wear nitrile gloves that meet OSHA standards. If there is skin contact with the ash, thoroughly
wash the skin with soap and water.
•
Wear ear protection that meets OSHA standards. The noise made during the burst process is within
the acceptable decibel rating for unprotected ears; however, ear protection is recommended.
•Never attempt to clean a DPF that is too hot to touch.
•A DPF must be securely clamped in place before a cleaning cycle is initiated.
•Unplug the DPF Cleaner before beginning any service work. Incorrect use or connections can
cause electrical shock.
•An extension cord may overheat, resulting in a fire. If you must use an extension cord, use the
shortest possible cord with a minimum size of 14 AWG.
•Use the DPF Cleaner only for the purpose of which it was designed. Use only those adapters
approved by the manufacturer.

The Cleaning Cycle
Automatic Reverse Cleaning Process
After a number of DPFs have been cleaned, the back pressure in the ash collection tank will increase to
a level that triggers an automatic reverse cleaning process for the internal cartridge filters. This consists
of small air bursts passing backward through the cartridge filters to remove ash from the filter media
and prolong cartridge life.
The display message spells out REVERSE CLEANING while this process takes place.
After the reverse cleaning is complete, the normal DPF cleaning process resumes.
Note: The first time the reverse cleaning process occurs, it is a signal for the user to purchase
replacement cartridge filters. At some point, the reverse cleaning process will no longer be successful,
and the cartridge filters will need to be replaced.
When this occurs, the display message will be INTERNAL FILTERS BAD. At this point, disconnect the
power cord and air line, and replace the cartridge filters as outlined in the section of this manual titled
Maintenance – Cartridge Filters.

Maintenance—Cartridge Filters
During operation of the DPF Cleaner, the contaminated airstream is drawn into an ash collector, where
its velocity is reduced by inlet baffle plates to provide even air distribution across the entire surface
area of cartridge filters. This design enhances filtration efficiency by establishing a uniform dust cake
on the filters. The airstream is then directed around the cartridge filters and down toward the bottom of
the collector, where the heavier particles accumulate.
The contaminated air then passes through the cartridge filters. The filter media strips most of the ash
from the airstream, and the air then passes into the clean air plenum and through a HEPA filter before
being discharged from the unit. When back pressure in the ash collector tank exceeds a preset value,
and the reverse cleaning process is no longer effective, a display message will prompt the user to
change the cartridge filters.
Replace the Cartridge Filters
This procedure describes how to replace the
cartridge filters using the Bag-out Kit included
when a new filter is purchased.
1. Shut off the machine, and remove the power
cord from the outlet.
2. Unlock and remove the cover to the upper
cartridge filter.
3. Use the cinch strap provided in the Bag-Out
Kit to securely attach a bag to the collar of
the cartridge chamber. See Figure 16.
4. Pull the used filter out of the dust collector
and into the bag. See Figure 17.
