The Lo-Pro Rotator attaches directly to the top of any DAW
True-KD™Series knee. It’s low build height allows KD Amputees
the convenience of knee rotation while still maintaining cosmetic
appearance in the sitting position.
The Lo-Pro Rotator features an
Unthreaded Side (with an unthreaded 4-Hole pattern) and a
Threaded Side (with a threaded 4-Hole pattern*Rubber Plug).
A. First, screw in the included M4 Screw
(by hand) partially into the Rubber Plug
and pull up to remove it.
B. Push and hold down the Button and rotate
until the Plug’s Hole lines up with one of
the unthreaded holes on the rotator’s other
side. If it is difficult to rotate, screw in 2
M6 Button Head Screws partially into the
Threaded Side to use as leverage.
C. With the Unthreaded Side against the
adapter, insert one of the included
M6 Button Head Screws (4mm hex)
through the 2 holes into a threaded hole
of the Wire Basket. Screw in, but do not
tighten. It’s recommended the button be
positioned facing forward.
D. Repeat steps B. & C. until all 4 M6 Button
Head Screws are screwed in. Torque each
screw to 7.4ft-lb (9.9Nm).
E. Return the Rubber Plug to its hole.
F. Now you may secure the knee to the bottom of the Lo-Pro
Rotator using the included 7
/16 Bolt (8mm hex). Torque the
bolt to 9ft-lb (12.2Nm).

ALIGNMENT
RECOMMENDED
BENCH & STATIC
Standard alignment procedure must be observed to obtain the
maximum benefits offered by this knee. All alignment
references should be taken from the center of the anterior
superior knee axis (commonly referred to as the Knee Center).
Knee Center is
recommended 5-10mm
posterior to TKA
(15mm Maximum,
as illustrated here)
A socket flexion
angle of 5°

DAW Prosthetic Knee Limited Warranty
The knee comes with a Limited Warranty for 2-years. It covers
manufacturer defects (excluding wear & tear). An additional 3
years of warranty coverage can be purchased for +15% of the
original cost of the knee. See full warranty statement at:
www.daw-usa.com/practitioner-resources/
Weight limit of this knee is 275lb (125kg)
Bumpers are not under warranty.
Tight screws and a straight cut of the tubing are a must. Not
following recommended use of components, including weight
limit and alignment, will void the warranty. Make sure to read
all instructions enclosed with the knee unit.
All repairs on the knee module must be done by a factory-
trained DAW technician. Any disassembly done on the knee
during the warranty period(s) will void the warranty (excluding
dissasembly of the extension spring housing).
Service Under Warranty
For all component repairs call DAW Industries right away. We
will ship a replacement knee the same day, which will become
your patient’s new knee. The replacement component is under
warranty for the time remaining on the original component.
The overnight shipping charge will be credited upon receipt of
the failed knee component.
Service Outside of Warranty
Knees not under warranty may be repaired by DAW. While any
unwarranted knee is being serviced, DAW will provide a rental
knee subject to availability. The DAW rental fee is listed in the
price list under each knee. The rental fee covers the period
DAW takes to complete the repair with ten (10) days allowed
for shipping in both directions. The same rental fee will be
charged every 30 days passed the initial rental fee period.
For any repair you must first contact our Technical Services
at 1(800)242-8669. This will allow DAW to best understand
the issue. Our Technical Support will immediately asses if the
repair qualifies as a “minor” or “substantial” repair. A “minor”
repair will be completed, as a courtesy, free of charge (you
will just pay for return shipping). A “substantial” repair will be
billed at a flat rate according to knee model. Upon return of
your repaired knee, you will be invoiced for the repair charge, if
any. When DAW receives the rental knee, your account will be
credited for the value of the returned knee
(Gold Preferred+ = FREE rental; Preferred = 33% off).
In the event your knee is unrepairable, you will be
notified immediately. The rental must then be returned to
DAW, 2nd day, within five (5) working days. The rental fee may
be applied toward the purchase of a new DAW knee.

Adjusting the Extension Stop Bumper
(Stability & Swing Phase Trigger Point)
Extension Stop Screw
(2.5mm hex)
To customize the “trigger point” of swing-phase, adjust the
Extension Stop Screw. Max adjustment is 2°.
Note: This adjustment will affect socket flexion slightly.
Turn the Extension Stop Screw (2.5mm hex):
Clockwise for earlier swing-phase initiation
(& less stance phase stability)
Counter-clockwise for later swing-phase initiation
(& more stance phase stability)
Cleaning Pneumatic Components
Using the Swing Adjustment Wrench (or 9mm wrench),
completely remove the Flexion Knob. Turn the Knob
counter-clockwise until it no longer appears to be
unthreading. The Knob pulls out of its chamber with a small
amount of force.
With the Knob removed, flex the Knee quickly & repeatedly
to clear out any debris from the air passage. Air should flow
smoothly with no restriction.
Using a Q-Tip, clean the chamber from which the Knob was
removed. The entire chamber should be dry.
Remove the Extension Screw (3mm Hex) from the Knob.
Remove the Needle and clean it of any debris or lubricant.
Apply a very light coat of wheel-bearing grease to the
Knob O-ring. Be sure the Needle remains dry.
Return the Needle to the Knob. Do not yet return the Screw
to the Knob. Press the Knob and Needle back into the
chamber of the knee. You will hear a “click” as the Knob
seats back into the chamber.
Turn the Flexion Knob clockwise. Initially, apply a small
amount of downward force while you turn to ensure the
threads catch. Gently screw it in until it stops. Do not tighten.
Turn the Knob counter-clockwise 2 rotations
(the factory setting for Extension).
While holding the Knob stationary with the Swing Adjustment
Wrench (or 9mm wrench), screw the Extension Screw back
into the Knob until 1 thread shows above the Knob
(the factory setting for Flexion).

Replacing or Trimming
the Extension Assist Spring
To replace the current Extension Assist Spring with the
Stronger spring included with your knee:
Completely remove the Pylon Clamp Screw (5mm hex).
Remove the pylon.
Flex the knee to full flexion.
Using a 12mm wrench, or crescent wrench, twist the
Lock Nut clockwise, the Spring Housing will extend
out of the knee as you twist the Lock Nut.
You can now pull the Spring out of the Housing .
Insert your new Spring into the Housing .
Unflex the knee to full extension and return the housing
to the knee making sure the groove for the
Pylon Clamp Screw lines up properly.
After returning the Pylon. Retighten Pylon Clamp Screw
(5mm hex) to 11ft-lb (15Nm)
Too much Extension Assist even with the lighter spring?
Complete steps A. through E. above
Using a grinding wheel, trim one or two coils (maximum) off one
end of the Spring. Smooth the trimmed end. Return the Spring to
the housing, trimmed end down. Continue with step G. above.

Adjusting Swing Phase Controls
(Flexion & Extension Dampening)
It is recommended your Patient take their first steps slowly!
This knee is engineered to conserve your Patient’s energy &
strength throughout the day. Very little energy is required to
initiate gate.
The DAW Pneumatics™Knob-and-Screw-Adjustment
provides exceptionally precise control of heel rise and
extension dampening. Perform these adjustments in
1/8-turn increments.
Needed for This Adjustment:
✔3mm hex key
✔Swing Adjustment Wrench (included) or a 9mm wrench
It is recommended to make your Extension Adjustment first,
then your Flexion Adjustment. Repeat adjusting Extension
then Flexion as needed.
Adjusting Extension Dampening:
In 1 /8-turn increments, turn the brass Extension Screw:
Clockwise to increase resistance
Counter-Clockwise to decrease resistance
Adjusting Flexion Dampening:
While holding the Extension Screw stationary (3mm hex key),
in 1 /8-turn increments turn the Flexion Knob:
Clockwise to increase resistance
Counter-Clockwise to decrease resistance
NOTE: Excessive adjustment of Extension Screw can jam
needle pin, eliminating full range-of-motion resistance control.
