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
