EZ Way Smart Stand®Safety & Maintenance Checklist
EZ Way, Inc.
The EZ Way Smart Stand®requires a minimum of servicing to keep it in good working order. Nevertheless, it is
important that certain basic checks be periodically made by maintenance staff to ensure on-going safety throughout the
life of the device.
The manufacturer suggests that the following components and operating points be scheduled for inspection at intervals
not greater than six months. Any detected deficiency must be rectified before the stand is put back into service.

5. Check mounting bolts of actuator top and bottom. Pay particular attention to top bolt hole for elongation.
Check actuator for the following.
☐Inspect the plastic housing for any dents or cracks.
☐ Inspect the cables to see if they have been cut or pinched.
☐ See if the actuator appears deflected when fully extended under load.
☐ Verify that the mounting points do not have any cracks or other defects.
☐ Apply a heavy grease to actuator mounting pins as needed.
☐ Verify that the inner or outer tubes do not have any dents, dings, or large scratches in them.
Contact EZ Way’s Service Department if the actuator shows any signs of
the issues listed above.

ACTUATOR
At six month intervals, attach a load equivalent to or within 100 lbs of the rated capacity of the
stand to the unit. Do not exceed the rate weight capacity. Raise and lower the load with the lift. Listen for
any unusual noises while operating the unit. With the test load applied to the lift, check all structural welds
for any signs of stress or fatigue cracks. If any unusual noises or cracks are found, stop using the stand and
call the EZ Way Service Department immediately!
Test the Emergency Stop Switch. If the switch does not stop the stand when activated, call the EZ Way
Service Department immediately!
Perform a functional test of the emergency lowering feature of the stand actuator if it is so equipped.
Perform a functional test of the anti-pinch feature of the stand actuator. This feature turns the
actuator off when lowering the stand arm if an obstruction is encountered.
Check all the wheels and brakes to make sure they are functioning properly. Hair that gets picked up
and wrapped in between wheels should be cleaned out so that the stand will roll easily.
Do a visual check for any damaged, missing or loose parts. Repair as necessary.
Check the entire harness for damage or wear, including the loops and stitching. If damage or wear is
present, discard the harness and order a new one. It is recommended that harness be replaced after one year
or if the sling shows any sign of damage or wear.
When cleaning the stand, do not spray any liquid cleaners directly onto the front panel graphics.
To clean, use a glass cleaner such as Windex, dampen a cloth and wipe the panel.
IMPORTANT NOTICE
It is the responsibility of the purchaser to ensure
that regular maintenance inspection is conducted
on this device by competent staff.

Advanced Smart Stand®Features
BATTERY MESSAGING
Charge Battery – For Battery Maintenance
When the battery level gets below 22.7 volts, the display reads ‘CHARGE BATTERY’.
Swap Battery – For Battery Protection
When the battery level gets below 22.3 volts, the display reads ‘SWAP BATTERY’ and only allows the
unit to go in the down direction.
REMINDER MESSAGING
Inspection Overdue – For Scheduled Maintenance
The purpose of the inspection overdue reminder is to notify the customer that the stand needs to be
inspected every 30 days.
FAULT MESSAGING
Duty Cycle Fault – For Actuator Protection
The stand actuators are rated for a specific duty cycle. What this means is that for every 20 minutes
of elapsed time, the stand is rated to run 5 minutes. If the stand is operated in excess of 5 minutes at a
time, the actuator may be damaged. When the duty cycle fault occurs, the following message comes up:
‘Actuator Duty Cycle Fault…Cooling’. When this fault occurs, the customer can lower the patient. After
lowering, the customer will need to wait 15 minutes to cool the actuator motor.
Actuator Overload – For Arm Protection
1. When an Up or Down command is executed, the circuit board monitors current consumed by the
actuator. If the actuator consumes too much current, the control will recognize this condition.
2. At this time an ‘Actuator Overload’ message will display. The ‘Actuator Overload’ may result from
lifting a patient/object that is too heavy, arm pinched against obstruction, or mechanical failure
(internal actuator binding, etc.).
3. To override an ‘Actuator Overload’, press the down key. The arm will only operate in the down
direction during a current overload. Note: This feature is available on all scale and non-scale units.
Weight Overload – For Arm Protection
1. When an Up or Down command is executed, the control monitors weight readings from the load cell.
If the weight is measured too high, the control will recognize this condition.
2. At this time a ‘Weight Overload’ message will display. The Weight Overload may result from
accidental lifting of a trapped harness or accidental lifting of an overweight patient.
3. To override a ‘Weight Overload’, press the down key. The arm will only operate in the down direction
during a Weight Overload. Note: This feature is only available on scale units.

Advanced Smart Stand®Features
Actuator Minutes – For Tracking Stand Usage
The Actuator Minutes function tracks the accumulated amount of raising and lowering time of the
actuator. With each minute of runtime the ‘Actuator Minutes’ register increments one. A typical lift
takes one minute of runtime. This read-only information provides accurate customer feedback of stand
usage within the care facility. In the event of an actuator replacement the ‘Actuator Minutes’ register can
be reset by calling an EZ Way Service representative.
Actuator Overload Counts – For Diagnostic Tracking with Actuator
The Actuator Overload Counts function tracks Actuator Overload occurrences. When an ‘ACTUATOR
OVERLOAD’ occurs the ‘Actuator Overload Counts’ register increments one. This read-only
information provides customer feedback for; accidental lifting of a trapped harness, accidental lifting of
arm against obstruction, or accidental lifting of overweight patient.
Lift/Stand Total Minutes – For Tracking Stand Usage
‘Lift/Stand Total Minutes’ function tracks the accumulated amount of raising and lowering time of the
actuator on the unit. The ‘Lift/Stand Total Minutes’ is not reset when an actuator is replaced. This read-
only information provides accurate customer feedback of unit usage for the entire life of the stand.
Volts= - For Battery Diagnostics
The ‘Battery Voltage’ function tracks the real-time voltage of the battery. This information is useful in
diagnosing issues related to battery level.
SW Rev. – For Software Diagnostics
The ‘Software Revision’ is used for tracking software changes. For example if the original code begins
