2 Safety Instructions
Caution!
Always wear adequate protective clothing (e.g. gloves, safety glasses, etc.) and use appropriate
tools (refer to page 4)!
Caution!
You may get injured if the product tips over or falls off a work surface (e.g. workbench)!
Secure the product to prevent it from tipping over or falling off any work surfaces!
Caution!
Unsecured screw connections can become loose while using the product.
This can lead to accidents, resulting in a risk of injury to the person being transported in the
product!
Always secure screws and nuts. If you have to undo secured screw fastenings, replace self-lock-
ing nuts and screws exclusively with new ones. To secure screws, you can also use a medium-
strength liquid thread lock substance (such as Loctite 241 or Euro Lock A24.20).
Caution!
Bald tires can lead to accidents.
This results in a risk of injuries for the person transported in the product!
For this reason, wheels with solid material tires such as PU or EVA foam must be replaced if the
material shows signs of cracking or damage, or when the tread becomes worn down to such an
extent that there is only 5 mm of radius left on the outer edges of the tire.
For this reason, the casing of pneumatic tires must be replaced if it is bald or shows signs of
cracking or other damage.
Caution!
Always observe the following guidelines:
• Times needed for adhesives to set,
• Torque indications for screw connections!
Non-compliance with these instructions can lead to malfunctioning of the product and accidents.
In such cases, there is a risk of injury to the person being transported in the product!
