EZI-WALK
Electric Rollator
USER MANUAL

Page 1
This intelligent Ezi-Walk Electric rollator is a portable electric rollator and shopping cart for those
with decreased mobility due to age or medical/health conditions. The system is classified according
to the user's action ability, providing intelligent anti-fall detection and maximum speed limit function.
At the same time, it has the function of intelligent intention perception. Automatically adjust the
operation status according to the user's use status and surface/terrain condition.
When travelling on the horizontal ground, the user can easily push the rollator by holding the
handgrips and the power is automatically adjusted according to the user's walking speed. When
travelling downhill, the rollator automatically produces resistance, which prevents the rollator from
sliding down quickly and causes potential safety hazards. When travelling uphill, the
auto-assistance will generate for easy uphill; if the user feels that the power is insufficient, the
constant assistance power can be started to travel uphill easily.

SAFETY SUMMARY
To ensure the safe operation of the rollator, these instructions must be followed:
GENERAL WARNING
DO NOT assemble or use this rollator without first reading and understanding this instruction sheet.
If you are unable to understand the Warnings, Cautions or Instructions, contact a healthcare
professional, authorised dealer or technical personnel before attempting to assemble this rollator –
otherwise, injury or damage may occur. Everyone should consult with their physician or therapist to
determine proper adjustment and usage of the rollator.
The rollator is NOT intended to be propelled while seated
A physician/occupational therapist should assist in the height adjustment of the rollator for
maximum support and correct brake engagement, and the fastening of the screw. Always ensure
screws are fastened to the connector, so that the connector can’t move when forced. Ensure all pins
fully protrude through adjustment holes. Ensure when pulling up and pressing down the brake
handle, the brake can be successfully engaged. Failure to follow these warnings can result in
personal injury.
Care should be taken to ensure that ALL handles, height adjustment locks, wheels, brakes or any
other functional or moving parts are in good working condition before operation. All wheels MUST
be in contact with the floor at ALL TIMES during use. This will ensure the rollator is properly
balanced. The brakes MUST be in the locked position before using the seat. When using the rollator
in a stationary position, the hand brakes MUST be locked.
In case of voice warning for charging under low power, the power icon will keep
flashing, and the brake system will be activated. At this moment, the resistance force achieves its
max. Please SWITCH OFF the system and use the rollator as a normal rollator.
DO NOT charge the rollator under wet or humid environment. The voltage used for charging shall
NOT exceed 240V. NEVER place the battery in water.
STABILITY WARNING
The Rollator can provide ambulatory assistance to an individual weighing up to 136kg, including the
weight of the contents of the bag.
The shopping bag has a weight limitation of 4.5kg
DO NOT go up inclines greater than 15°or go down inclines greater than 5°when using the rollator.
DO NOT ride the rollator with all your weight on the armrests or lean disproportionately on one of
the armrests.

2. Switch off: long press , after “beep” switch off complete.
Power Resistance Mode: short press to switch gears, 01-03 gears, resistance gradually
reduced (01>02>03), with anti-fall function.
This mode is mainly used for rehabilitation training for users with weak muscle strength. When
pushing the rollator, there is always a resistance to support the user to walk, preventing the wheels
from speeding up and causing the user to fall.
Anti-fall Function: When pushing the rollator, if the speed suddenly becomes faster, the system
will automatically make an emergency brake to stop the rollator and the screen will show "EE", after
releasing the handgrip, the anti-fall will be lifted, and "EE" will disappear.
Note: The thumb button is invalid in the resistance mode.

Power Assistance Mode: short press to switch gears, C1-C3 gears, auto-assist strength and
speed gradually increase (C1<C2<C3), maximum speed 4.8KM/H.
Auto Assist: Hold the handgrip and push the rollator. At this time, auto-assist will be generated
automatically. When pushing forward, it will help forward, and when pushing backward, it will help
backward. The faster the speed, the more obvious assistance strength; the higher the gears, the
more obvious assistance strength. When travelling downhill, it will automatically generate resistance.
When travelling uphill, if the user feels that the power is insufficient, the constant assist power can
be started to travel uphill easily.
Constant Assist (Thumb Button): hold the handgrip, press the thumb button (the icon
lights up), the assistance strength will be increased.
Threshold Crossing Mode: select the assistance gears C1-C3, hold the handgrip to stop the
rollator, hold on the thumb button, the front wheel will lift automatically to a certain angle, to prevent
the rollator from turning over accidentally.
Switching Direction: short press , direction can be switched. If the icon keep flashing
voice prompt “attention to reversing”, it means backward.
Multi-Function Display Zone Switching: after switched on, short press , the display can be
switched between total travel mileage, single travel mileage, travelling time and rollator attitude.
Handgrip Detection:
(A) Lock mode When your hand leaves the handset display for more than 5 seconds or 15cm away
from the handset display, the system will automatically lock, the screen displays "LL". At this time,
the rollator can’t be moved.
(B) Active mode Hold the handgrip within 15cm from the handset display. If the rollator is under the
lock mode, the screen will display "LL" and keep flashing. At this time, press thumb button, then "LL"
will disappear.
