C. Nozzle Suction Power is Weak
1. Bag may be full or contain fine particles such as drywall dust or talc.
2. Filters may be dirty and need replaced.
C.1. There is no suction at the hose
C.1. Step 1.
The tool activation dial/rotational valve handle should be in the tools “ON” position.
C.1. Step 2.
Remove the hose and check for a clog in the hose. (If clogged remove the clog).
NOTE: If hose is clogged there will be suction at the hose inlet on the back path of the vacuum.
C.1. Step 3.
If there is no suction at the hose inlet at the back path:
1. Remove the tool activation dial/rotational valve handle.
2. Remove the 7 (seven) screws holding on the air hose path and hose inlet connector.
3. If clogged remove clog and re-assemble.
C.2. There is no suction at the nozzle
C.2. Step 1.
The tool activation dial/rotational valve handle should be in the tools “OFF” position.
C.2. Step 2.
Check the nozzle tray and agitator/brush roll for clog, clean agitator/brush roll as required.
C.2. Step 3.
Remove the dust cover and turn the vacuum “ON”, in carpet mode. The bag should inflate assuring the air path is open and
the direct air motor is working.
C.2. Step 4.
If suction is still weak:
1. Remove the agitator/brush roll, nozzle cover, and direct air motor inlet cover.
2. Check for clogs in the inlet duct and direct air motor inlet, if clogged remove the clog and test again.
C.2. Step 5.
Models .5+ and newer, if suction is still weak:
Turn vacuum over and remove the clean out door and check and remove any clogs.
NOTE: You may turn the vacuum on and check the suction at the clean out door. This is done with the dust cover
installed, and with the upper motor only, if you have suction the air path is open and the clog is in the direct air
motor.
Models .5 and older, if suctions is still weak:
Remove the back cover to check the air path. If the air path is clear, the clog is in the direct air motor.
C.2. Step 6.
If clog is in the direct air motor remove the direct air motor (See
II. Maintenance Procedures, I. Removing and Replacing the
Direct Air Motor
) and the remove the outer scroll housing and check for any clog.
C.2. Step 7.
Re-assemble the vacuum and retest.
