Warning
• Patient Hazard, Equipment Damage
• EN 62353 and/or IEC 60601-1 requirements must be
satised during repair, modications and inspections of
medical electrical equipment.
• To ensure that equipment functions faultlessly and
without presenting any hazard after service interventions,
it must be subjected to the test procedures stipulated for
the dierent device categories.
• A device is considered to be unsafe, when:
- it cannot be repaired
- the user does not wish to have the device repaired.
In this case, the operator must be informed in
writing of the hazard presented by the device.
The same remark must be annotated on the
service report and on the service invoice..
eleCtrICal safety
Warning
• Equipment Damage •
• The regulations about handling ESD sensitive components
must be observed.
leakage Currents
MeasurIng equIpMent
The measuring equipment used for the electrical safety
tests must be inspected and calibrated at regular intervals
(refer to manufacturer of measuring equipment).
The measurement results must be documented.
eBIke III BasIC / CoMfort
The eBike III basic/comfort ergometers are protection
class II equipment (no connection to protective ground).
The necessary electrical safety tests for these devices
together with the limit values are listed in the
chapter titled “eBike III basic/comfort - Preventive
maintenance“.
teCHnICal safety InspeCtIons and
InspeCtIons of tHe MeasurIng systeMs
The load unit is recommended to be inspected to the
approved regional standards at intervals of 2 years by a
GE Medical Systems Information Technologies authorized
service technician, and calibrated or repaired if necessary.
Calibration instructions for the NIBP module can be found
in this Service manual. Follow these instructions to display
the BP values with the test setup according to
EN 1060-1 and EN1060-3 or appropriate regional standard.
The measurement results must be documented. Warning
• Patient Hazard, Equipment Damage
• Use original spare parts only.
• For information about product changes, refer to the
manufacturer’s original documentation only.
• Observe the fuses’ original ratings, characteristics and
Ampere interrupting capacity.
• Parts of the device that ensure its safe operation must be
neither damaged nor obviously unsuitable. This applies to
insulation and insulating components in particular.
• Power cords must be visually inspected for signs of
damage before connecting them to the power line.

1. Check the setup for stability, adjust with leveling device if required.
Expected result: No instability Pass/Fail
2. Visually inspect the device:
- inspect cables / power cord
Expected result: No damage or wear detected Pass/Fail
Note
• eBike III basic / comfort is a protection class II device (no connection to protective ground).
• Preventive maintenance is recommended to be performed every 2 years.
Warning
• Hazard, Equipment Damage
• When work at the bottom of the eBike III is required (e.g. access to electronic moduls, exchange
of load unit or installation of COM module) the eBike III should be carefully placed on one side
by grabbing it at the handlebar and the saddle.
• DO NOT tilt the eBike III forward to stand on the handlebar - this is an unsecure and instable
position!

3. Check cranks and pedals:
- pedals have no signs for damage / wear
- pedals securely xed on cranks
- crank screws securely xed (torque 40 Nm ± 2 Nm) on axis
Expected result: Cranks and pedals OK Pass/Fail
eBike III basic
- Check bellow on saddle for damage / wear / cracks
- Check handlebar adjustment (angle)
- Check saddle height adjustment
- Check that the clamping levers (saddle [height] and handlebar [angle] adjustment) are tight.
Grease the thread of the saddle clamping lever.
(Use of an universal high-performance lubricant such as OKS 470 is recommended.)
eBike III comfort
- Check handlebar adjustment (angle)
- Check that the clamping lever is tight.
- Check electrical saddle adjustment: adjust minimum and maximum saddle height;
then return saddle to mid-level
- Check correct indication of saddle height display
- Check that the clamping lever for handlebar adjustment (angle) is tight
Expected result: Adjustments work and levers are tight, thread properly greased Pass/Fail
4. Using the power cord, connect the device to the mains power line and place the power switch in the ON position
Wait for self test to end:
- check LCD for error messages (refer to „Turning the System On“ on page 60)
- check the software version in the service menu for correct version GF 1.x
(refer to „Software update“ on page 78)
- check the “error log le“ in service menu (refer to „Error log“ on page 67)
Expected result: Device powers on without errors, FW is correct version, no errors logged Pass/Fail
5. Check speed indication (rpm) is displayed on LCD and the additional speed indication on the patient display.
Check noise level of idling drive unit (for example, for grinding noises or noise from the bearing)
Expected result: Speed displayed on both displays and no noticeable noise Pass/Fail
6. Units with NIBP module:
- Check cu tubing and tubing connections, microphone connectors
- Check blood pressure measurement on test subject at rest (refer to the „eBike III operators manual“)
- Check blood pressure readings are displayed on LCD
Expected result: BP values are displayed and in proper range Pass/Fail
7. Set manual load (see „Manual Load“ on page 66), change load (for example, 50 W, 100 W)
- Check load level and load indication
Expected result: Load is set and changes as expected Pass/Fail
8. If ergometer is remote controlled from ECG recorder or PC-ECG system:
- Check connecting cable
- Check load control via ECG recorder or PC ECG system
- Check remote start if applicable
Expected result: Ergometer can be controlled by external unit Pass/Fail
