Solution
In order for a step to register, the pedals must pass
each other completely. This ensures that the magnet
on the treadle passes the step sensor. Make sure
treadles are not locked in treadmill mode and that they
are moving enough to register a step.
Be sure step sensor wire is connected at rear of
machine.
Make sure treadles are centered between uprights
and treadle is not contacting upright during use. If not
centered, remove rear plastic covers to access rear
baseplate bolts. Loosen bolts slightly to allow treadles
to be centered. Once centered, tighten outer two bolts
securely then tighten inner bolts securely.
Disconnect power cord from machine
!
and wait 5 minutes to ensure no residual
power remains.
Remove left side plastic drive cover to expose "v" belt
drive line.
Using a ½" wrench, tighten the bolt that attaches the
4½" drive pulley to the drive shaft while holding the
drive rollers still. Reinstall plastic drive cover.
If knocking sound seems to be coming directly from the
rear roller, check igus bushings and replace if cracked.
Check and tighten both upper and lower bolts that
connect the hydraulic cylinders to the unit. Make sure
that the spacers on the cylinder studs are installed.
Re-calibrate machine using Calibration procedure in
this manual.
1. Cycle power off and on.
2. Put the machine in calibration mode (see Calibration
procedure in this manual) but do not start the
Calibration routine.
3. Remove right rear plastic cover to view LED
diagnostics on motor control board (MCB).
Machine is on. Current is active. Do not touch
electrical components, to avoid risk of electrical
shock.
4. Locate LEDs C & D on the motor controller board.
LEDs may be lit or unlit.
5. Manually advance the treadle with your foot, and
check if either LED is blinking. If C is blinking, then
speed and step sensor jumper wire connections
are reversed. Unplug both and switch to the correct
locations.
6. If neither LED is blinking, then the speed sensor
signal is not reaching the MCB. Check that the speed
sensor wire is connected securely to the jumper wire
at rear of machine. Make sure wire is not crimped or
cut, and make sure other end is connected securely
to P1 on the MCB. If LED D still does not flash, contact
customer service.
Note: Do not progess to next step until D light is
flashing and speed sensor has been properly
adjusted.
