CAUTION
CAUTION
1-2 During Use
・ Walk with the Rollator while taking care that the wheels do not become inserted in a groove, such as a groove of a
railway crossing, escalator, or elevator. A wheel in a groove 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 achieved, 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 verifying that the levels 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 remove the center cap. If debris or water enters the interior, the predetermined brake force will not be
achieved, 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.
・
Never 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
device failure, resulting in an accident.
・
If water enters the product, apply the brake five or six times prior to use to verify that the brake works. If the brake
does not work, apply the brake several times, verify brake force recovery, 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 may lead to
poor operation and/or device failure, resulting in an accident.
・
Do not carry the Rollator itself by holding the tires. Doing so results in the risk of fingers getting pinched between the
tire and frame.

Device Features and Component Names
2-1 Device Features
When installed to a Rollator, the CONPAL unit (Speed Control unit), automatically activates the brake at the time of
sudden acceleration, preventing falling during Rollator use.
Unlike a conventional resistance brake system, the CONPAL unit activates 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.

3. Replacing the Tire
3-1 Checking if the Tire Needs to Be Replaced
・ There are grooves on the outer periphery of the tire. Check if the grooves exist. (Figure 1 and Figure 2)
・ If the grooves have 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.
