Turn off the pump and unplug the power cord.
EXPAND THE ROLLER ASSEMBLY
Adjustable Model
• Hold the feed rate control securely, use the
cover as a wrench and quickly (snap)
rotate the roller assembly clockwise to
expand the roller assembly. The tube will
be pressed against the tube housing wall.
Figure I
Proceed to step
6.
NOTE: Clockwise is viewed from facing the
head of the pump.
Fixed Output Model (manufactured before
04/29/11)
Only the Stenner fan
brake tool should be used for this step.
a.
Insert the fan brake tool into the vent in
the rear of the motor housing. Refer to
the figures below.
NOTE: The fixed output pump doesn’t
have a clutch so the fan brake keeps the
shaft from rotating when expanding the
roller assembly.
b.
Holding the pump securely, use the cover
as a wrench and quickly (snap) rotate the
roller assembly clockwise to expand the
roller assembly. The tube will be pressed
against the tube housing wall.
Figure I & J
NOTE: Clockwise is viewed from facing the
head of the pump.

Remove the fan brake tool. Proceed to
step

Fixed Output Model (motor vent with key
slot, manufactured after 04/29/11)
a.
Slide one latch out to remove it from the
tube housing. Insert the latch end into the
key slot in the vent in the rear of the
motor housing. While pressing the latch
into the rear of the motor, gently rotate
the cover clockwise until it stops. Refer to
the figures below.
b.
Holding the pump securely, use the cover
as a wrench and quickly (snap) rotate the
roller assembly clockwise to expand the
roller assembly. The tube will be pressed
against the tube housing wall.

Align the center of the inverted cover with the center of the roller assembly so that the three holes on the face of the cover align with the three knurled lugs
on the roller assembly. Position the cover feet near the bottom.
Figure H
