Step 4: Lower upper seat frame onto lower mainframe and
secure using 1x M10x25mm bolt, 1x M10 Nylock nut, 3x
21*11*2 washers and L-pin.
Note: Tighten the M10x25mm bolt, washers and Nylock until
lightly snug only. Over-tightening will prevent the seat from
rotating. Use the L-pin to tighten the upper seat frame once
rotated into place.

Step 5: Secure right pedal onto Crank arm. The
pedal threads have a blue coating which will feel very
tight when threaded onto the crank arm. This is a
type of thread locker, and once in contact with the
crank arm threads will activate in approximately
15minutes.
Caution! Extreme over-tightening could damage the
aluminum threads on the crank arm.
Note: Allow 15 minutes for the
thread-locker to activate before
first time use.
Check pedal tightness on a regular
basis and tighten as needed with a
15mm wrench.

Note: A large bucket is required for filling (Not included)
In areas where tap water quality is known to be
poor, FDF recommends the use of distilled water.
Tank filling and water treatment
Open the rear upper yellow tank plug and insert hose into
tank (rotating the impeller slightly may be necessary to al-
low the hose to pass), move the tank adjuster handle to
level 20 and begin filling. Do not fill the tank higher than
the level indicator on the front of the clear shell. A prop-
erly filled tank holds approximately 8liters of water.
Warning: Do not under any circumstances put
fingers into the tank. Use the end of the hose to
move the impeller should the need arise.
Water Treatment Procedures:
1. Add Chlorine tablet.
2. Wait a minimum of 72 hours.
Then add very small amount of blue
dye and check for desired color. Im-
portant! Do not add blue dye for at
least 72 hours following Chlorine
treatment. The blue dye adds visual
appeal as well as cutting down the
amount of light affecting the tank water,
thus extending the amount of time be-
tween water treatments.
Note: The blue
dye is extremely
concentrated and
will readily stain
carpet or clothing.
Caution: Use a drop cloth when filling or
adding blue dye

CAUTION
Caution: It is important that a drop
cloth be used under the fluid tank whenever
the tank plug is opened for water treatment.
The level of resistance is deter-
mined by the level indicator located
on the front of the tank. Level one
indicates lightest resistance, level
twenty represents heaviest resis-
tance. Allow three to four seconds
after adjusting resistance handle for
the correct resistance level to be
achieved.
Long term water treatment:
Do not use any water treatment other than the tablets
supplied with this machine. For replacement tablets, con-
tact your local First Degree Fitness distributor.
Water treatment schedules for the E720 will vary according
to the fluid tanks exposure to sunlight, but expect 8-12
months near a bright, sunlit window and 2 years or more for
a darker location. At the point of finding the water slightly
cloudy, add a Chlorine tablet. Remember to wait 72 hours
following the chlorine tablet before adding the blue dye as
the Chlorine tablet is extremely concentrated.
Important: Do not fill past the calibration mark as indi-
cated on the tank level sticker or water spillage may occur.
See tank filling/water treatment page for details.
Long term water treatment and basic operation
Resistance:
Warning:
Use two hands when either raising or lower-
ing the control arm as pictured.
Removing hands or feet before the crank
comes to a complete stop while training can
cause injury. The crank is direct drive so as
to allow both forward and reverse rotation
during training.

10
Chain tensioning bolts: Allows for tightening the chain or
adjustment from side to side. Make sure when tightening
only to adjust the same amount for both bolts, otherwise the
sprocket will be misaligned.
Note: Tightening the right bolt only will pull the right side of
the crank assembly toward you, tightening the left will pull the
left side toward you. Use this feature to realign the rear with
the front sprocket if needed or when changing to a new chain.
The E720 Pedal: This pat-
ented design allows for usage
in both the recumbent posi-
tion and for sitting/standing
upper body workouts.
L-pin: Loosen
when rotating
the control arm
and tighten
(snug only)
once the de-
sired position
has been
reached.
T-pin: The T-pin locks the con-
trol arm in any one of 72 different
positions throughout its 360 de-
gree range of motion. Pull up
the T-pin to allow the control arm
to rotate while supporting the
control arm with the other hand.
Crank arm bolts:
Loosen all 8 bolts
slightly before adjusting/
tightening chain.
The E720 Control Arm
Inspection plate: Open to check
chain tension.
Warning: Do not check
chain tension by hand!

Item Timeframe Instructions Notes
Seat and Frame. Weekly. Wipe down weekly with lint free
cloth or more often with heavy club
use.
PK belt tension. Monthly. Check monthly for signs of slippage.
Adjust/tighten as required.
Tank and water treatment. 12 months to 2 years. Follow instructions as specified in
the “Water Treatment” section of
this manual.
Chain drive. Check every 100 hours for correct
tension. Open the inspection plate and check
tension using a screwdriver or other
tool. Tighten as required using
chain tensioning bolts located at the
end of the control arm.
E720 pedals. Tighten weekly using 15mm box
wrench (supplied) The pedals should be checked on a
regular basis. A loose pedal can
cause damage to the crank arm alu-
minum threads, requiring replace-
ment.
Maintenance chart.

12
Fault Probable Cause Solution
Water changes color or becomes
cloudy. Rower is in direct sunlight or has
not had water treatment.
Change rower location to reduce direct exposure to sunlight.
Add water treatment and blue dye or change tank water as
directed in the water treatment section of this manual.
Knocking noise from inside the control
arm while training, especially when
changing directions.
Chain requires tightening or ad-
justment. Open inspection plate located on front of control arm and
check tension using a screwdriver or other tool. Use the
chain tensioning bolts located at the rear of the control arm
to tighten or adjust as needed. The chain should have
approx 3mm of slack when properly adjusted. See P.10 for
details.
Pedals slip during hard training. PK tank belt requires tightening. Remove large inspection plate next to the tank, insert a long
tool to push the rear end cap out from the inside, exposing
the tank belt tensioning bolt. Loosen tank bolts slightly. Re-
move upper rubber belt cover to expose the PK belt.
Tighten the tank tensioning bolt until the belt is too tight to
be twisted from side to side more than 45 degrees by hand.
See P.14 for details
Pedal is loose (either left or right) and
cannot be retightened. Aluminum crank arm threads are
stripped.
Contact service center for replacement. Then check weekly
as recommended.
Computer screen illuminates, but does
not register when rowing.
Loose or failed connection/
Sensor gap too wide (see erratic
computer display).
Check that the computer lead is connected properly. If con-
nected properly check sensor gap. Contact your local ser-
vice center if this fails to address the problem.
The E720 computer does not illuminate
after battery installation. Batteries installed incorrectly or
need replacing. Reinstall batteries in correct position and try again. If the
LCD screen fails to illuminate, try rotating the batteries
slightly in the computer. If this fails, contact your local ser-
vice center.
The E720 computer display is erratic/
slow while displaying RPM and WATTS Gap between sensor and mag-
netic ring is too wide. Remove inspection plate and check sensor gap and that
magnetic ring is not wobbly.

Step 1
Step 1: Remove large metal in-
spection plate as shown above
right.
Step 2: Using a long tool, push out
the rear end cap as pictured above
right. This will give you access to
the tank tensioning bolt (shown bot-
tom right).
Step 3: Loosen both the rear and
front tank bolts slightly as shown
left. Remove front rubber belt
cover.
Step 4: Using a 6mm Allen key,
tighten the belt using the tank ten-
sioning bolt until the belt no longer
slips during hard rowing.
Note: Do not over tighten tank
bolts.
