SYMPTOM:
ALL ZEROS ARE REGISTERING
ON MODULE.
If all zeros register on the display when the machine is
in motion, there could be a faulty encoder circuit
board, broken or loose wire connectors.
With the top, black, plastic cover removed, slowly
move the handles up and down. A plastic
encoder disc should be seen rotating through a
slot that houses sensors. Check to be sure that
the disc is clean and the encoder circuit board
and the module are in tact. If no mechanical mal-
function is visible, the encoder circuit board may
be faulty and should be replaced. If necessary, contact
Heart Rate, Inc. for further information.
SYMPTOM:
LCD DIGITS FAIL TO ILLUMINATE
If the display window is ruptured and the glass
top on the LCD is broken, the digits under the
broken area will fail to illuminate. The module will
need to be removed and returned to Heart Rate,
Inc. for LCD replacement and repair. To remove
the module, remove the four screws that mount
the module to the machine and disconnect the
wires from the module. The machine can be used
while the module is out for repair.
SYMPTOM:
MACHINE SQUEAK.
A lack of lubrication can cause a squeak in the
foot pedal shaft. If rotating the foot pedal while
standing on the pedal causes a squeak, lubricate
the shaft/pedal interface. If squeak remains,
remove the snap ring from the end of the pedal
shaft with snap ring pliers being careful not to
over extend the ring. Remove the aluminum foot
pedal and degrease the shaft and pedal hole. If
necessary, use fine sandpaper to smooth the
shaft surface. Apply grease liberally and
reassemble the pedal. Be sure that the snap ring
is fully engaged in the snap ring groove.
SYMPTOM:
MACHINE IS “STICKY”,
IRREGULAR OR HARD TO MOVE.
The foot pedals and handgrips are attached to
metal bars that move up and down inside C
shaped metal channels. The bars have plastic
rollers and slides that guide the bars through the
channels. Over time the lubricant in the channels
picks up dust and lint and dries out producing a
“sludge” tar like coating that prevents smooth
machine operation. Remove the tar like coating
with paint thinner on a rag and the machine will
function like brand new (see page 15).
SYMPTOM:
OIL LEAK FROM HYDRAULIC
ADJUSTMENT KNOB
An oil leak from the hydraulic knob (brass knob)
indicates either a loose connection or a malfunction
in the needle valve. Tighten the nut on the needle
valve if it is loose. If leak persists the valve must
be replaced. Do not remove the defective valve
until you receive the new one. Detailed installation
instructions will be included with the replacement
valve.
SYMPTOM:
OIL LEAK FROM RESERVOIR
ON TOP OF HYDRAULIC MOTOR
If oil leaks from the top seal between the black
plastic cap and the plastic bowl, tighten cap by
hand. If oil leaks from the threads at the base of
the accumulator, tighten by turning clockwise
with a wrench. If reservoir is physically damaged
and a replacement is required, do not remove the
reservoir until you receive a new one. The
replacement reservoir will include detailed
installation instructions. DO NOT USE THE
MACHINE UNLESS THE RESERVOIR IS AT
LEAST 3/4 FULL OF OIL.
