Troubleshooting guide:
Fault
Water changes color or becomes
cloudy.
Knocking noise from inside the control
arm while training, especially when
changing directions.
Pedals slip during hard training.
Pedal is loose (either left or right) and
cannot be retightened.
Computer screen illuminates, but does
not register when rowing.
The E720 computer does not illuminate
after battery installation.
The E720 computer display is erratic/
slow while displaying RPM and WATTS
Probable Cause
12
Rower is in direct sunlight or has
not had water treatment.
Chain requires tightening or ad-
justment.
PK tank belt requires tightening.
Aluminum crank arm threads are
stripped.
Loose or failed connection/
Sensor gap too wide (see erratic
computer display).
Batteries installed incorrectly or
need replacing.
Gap between sensor and mag-
netic ring is too wide.
Solution
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.
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.
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
Contact service center for replacement. Then check weekly
as recommended.
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.
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.
Remove inspection plate and check sensor gap and that
magnetic ring is not wobbly.
