1-2 During Use
・ Walk with the Rollator while taking care that the wheels do not become inserted in a groo e, such as a groo e of a
railway crossing, escalator, or ele ator. A wheel in a groo e may lead to falling.
・ Be sure to use the product with the center cap installed. If debris or water enters the interior, the predetermined
brake force will not be achie ed, resulting in the risk of falling. If the center cap comes off, contact the distributor.
・ Refrain from using the product on a wet surface. Doing so may lead to slipping and an accident.
・ Be careful of bumpy and inclined surfaces. Do not use the product on steep sloping roads.
・ Be sure to use the product after first erifying that the le els of adjustment on the left and right are the same. Failure
to do so may lead to an inability to maintain straightness, resulting in an accident.
1-3 During Repair and Inspection
・ Do not loosen, disassemble, or modify parts connected by bolts and nuts. When disassembly or repair is required,
always request the distributor to perform the task.
・ Do not remo e the center cap. If debris or water enters the interior, the predetermined brake force will not be
achie ed, resulting in the risk of falling.
・ If you replace a tire, replace both the left and right tires. Replacing only one tire results in the risk that a difference in
brake force will arise between the left and right.
・ Ne er apply grease or oil to the product. Doing so may lead to an inadequate brake force, resulting in falling.
1-4 During Storage
・ Do not store the product in a location exposed to water, wind, or rain. Doing so may lead to poor operation and/or
de ice failure, resulting in an accident.

Device Features and Component Names
2-1 Device Features
When installed to a Rollator, the CONPAL unit (Speed Control unit), automatically acti ates the brake at the time of
sudden acceleration, pre enting falling during Rollator use.
Unlike a con entional resistance brake system, the CONPAL unit acti ates the brake only at times of sudden
acceleration, making it possible for the user to walk smoothly without the brake applied during normal walking.
The CONPAL unit (Speed Control unit) is a brake capable of suppressing acceleration; it cannot fully stop the tires.
Do note, therefore, that there is a risk of falling when the user becomes fully separated from the Rollator, for
example. Caution is required.
Conventional Rollator
The user cannot keep up with the rollator
and falls!
Automatic braking at times
of sudden acceleration
Light
walking during
normal walking
The brake is activated at times of sudden acceleration only,
preventing falling!

3. Replacing the Tire
3-1 Checking if the Tire Needs to Be Replaced
・ There are groo es on the outer periphery of the tire. Check if the groo es exist. (Figure 1 and Figure 2)
・ If the groo es ha e worn away on either the left or right tire, the tire needs to be replaced. Be sure to contact
the distributor.
・ At this time, replace both the left and right tires. Replacing only one tire results in the possibility that a
difference in brake force will arise between the left and right.
