WARNING
• Walk with the rollator while taking care that the CONPAL unit is not caught in a gap or groove, such as a
gap at a railroad crossing, a gap of an escalator, or a sill groove of an elevator. A wheel caught in a gap
or groove can cause falling.
• Be sure to use the product with the center cap installed. If dirt or water enters the interior, the
predetermined brake force will not be achieved, resulting in falling. If the center cap comes off, contact
your distributor.
• Do not attempt to adjust the brake force. If brake force adjustment is required, contact your distributor,
Brake force that does not match your physical activity level can cause an unexpected fall.
• Clean the surface of the CONPAL unit before use.
If it is dirty, the hand brake performance may be deteriorated.
• Do not drag the CONPAL unit while keeping the brakes applied.

1.5 During Repair and Inspection
WARNING
• Do not loosen, disassemble, or modify parts connected by bolts and nuts. When disassembly or repair is
required, be sure to contact your distributor.
CAUTION
• Do not remove the center cap. If dirt or water enters the interior, the predetermined brake force will not be
achieved, resulting in falling.
• When replacing tires, replace the left and right tires at the same time. Replacing only one tire will result in
uneven brake force between left and right.
• Never apply grease or oil to the product. Doing so can cause insufficient brake force, resulting in falling.
1.6 During Storage
Store the product indoors.
Wipe the moisture off before storing. Failure to do so may cause rust.
WARNING
• Do not store the product in a location exposed to water, wind, or rain. Doing so can cause malfunction and/or device
failure, resulting in an accident.
• If water enters into the product, test the brakes in a safe place by applying the brakes five or six times to check the
brakes work.
If the brakes do not work, repeat the test until the brakes work, and then use the product.
• Do not store the product in the trunk of a car or any location that reaches high temperatures. Doing so can cause
malfunction and/or device failure, resulting in an accident.

2 Device Features and Component Names
2.1 Device Features
When installed to a rollator, the CONPAL unit (Speed Control unit), automatically activates the
brakes at the time of sudden acceleration, preventing falling while using the rollator.
Unlike a conventional resistance brake system, the CONPAL unit activates the brakes only at times
of sudden acceleration, making it possible for the user to walk smoothly without the brakes applied
during normal walking.
The CONPAL unit (Speed Control unit) is a brake system capable of suppressing acceleration; it
cannot fully stop the rollator. Be careful as you may fall when you walk too far behind the rollator to
lose hold of the grip.
Conventional Rollator
The user cannot keep up with the rollator
and falls!
Automatic braking at times of
sudden acceleration
Smooth walk during
normal walk
The brakes are activated at times of sudden acceleration
only, preventing falling!

3 Daily Inspections and Care
3.1 Checking When to Replace Tires
Inspect your tires for wear and consider whether to replace them.
Each tire has grooves on the rubber surface as shown in the figure to the
right. (at three places)
If any of these grooves is worn down to a flat surface, the tire needs
replacement.
Immediately stop using the product, and contact your distributor.
If grooves on your tires are worn down in two or three months (premature
wear), it could have been caused by dragging the CONPAL unit. Take the
corrective measures below to solve the problem.
Corrective measures
If your tires are worn down prematurely
• Brake force adjustment
The brake force may be too high. Have the brake force reduced
slightly while maintaining safety.
If brake force adjustment is required, contact your distributor.
• Slow-speed walking
As you walk faster, the tires are more likely to spin out.
It is recommended to walk on a concrete or asphalt pavement at a speed of 3.5 km per hour.
Walk very slowly on uneven surfaces such as cobblestones.
Note: Walking speed of 3.5 km per hour is equivalent to walking speed of approximately 1 m
per second.
• Periodic inspection
If an abnormality is found, immediately stop using the product and contact your distributor.
Even if there is no abnormality, it is recommended to have the product inspected once a year.
CAUTION
• Replace the left and right tires at the same time.
Replacing only one tire will result in uneven brake force between left and right
