1. Check wear of hanger assembly bushing by moving hanger assembly up and down.
If hanger assembly moves up and down and the thickness of 2 quarters can be inserted
between hanger assembly and load cell the hanger assembly needs to be replaced.
2. Check all bolts to ensure they are tight.
3. Check boom to hanger assembly pivot bolt, peel rubber back to
assure nut is tight and cotter pin is in place. Check boom to mast pivot
bolt by removing plastic cap to assure nut is tight and cotter pin is in
place. If plastic cap is missing order replacement.
4. Check the point where sling hanger and hanger spreader bar meet. If excessively
worn, replace the bushings immediately. The hanger spreader and sling hanger wear
points need to be checked for wear. If hooks appear worn, call EZ Way for instructions.

EZ Way Smart Lift®Safety & Maintenance Checklist
EZ Way, Inc.
“Your Total Patient
Lift Solution”
The EZ Way Smart Lift®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 lift 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.

Test the Emergency Stop Switch. If the switch does not stop the lift when activated, call the EZ Way
Service Department immediately!
Perform a functional test of the emergency lowering feature of the lift actuator if it is so equipped.
Perform a functional test of the anti-pinch feature of the lift actuator. This feature turns the actuator off
when lowering the lift 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 lift will roll easily.
Do a visual check for any damaged, missing or loose parts. Repair as necessary.
Check the entire sling for damage or wear, including the loops and stitching. If damage or wear is
present, discard the sling and order a new one. It is recommended that slings be replaced after one year or if the
sling shows any sign of damage or wear.
At six month intervals, attach a load equivalent to or within 100 lbs of the rated capacity of the lift to
the unit. Do not exceed the rated 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 lift and call the EZ Way Service
Department immediately!
When cleaning the lift, 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.

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 lift needs to be
inspected every 30 days.
FAULT MESSAGING
Duty Cycle Fault – For Actuator Protection
The lift actuators are rated for a specific duty cycle. What this means is that for every 20 minutes of
elapsed time, the lift is rated to run 5 minutes. If the lift 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 sling 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 Lift®Features
Actuator Minutes – For Tracking Lift 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 lift 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.
