3.3 Safety Instructions for Assembly
WARNING
Use of alternative seating systems
Serious injuries to the user due to missing anti-tipper
► If the product is fitted with an alternative seating system or seating shells from other manufacturers, special
attention must be paid to static stability.
► The qualified personnel is obligated to ensure the static stability of such a combination.
► Using an anti-tipper may be required depending on the centre of gravity.
► Verify that the anti-tipper has been installed and adjusted properly.
CAUTION
Unsecured screw connections
Pinching, crushing, tipping over, falling of user due to assembly errors
► After all adjusting/readjusting work, retighten the mounting screws/nuts firmly. Observe any torque settings
which may be specified.
► Any time you loosen a screw connection with thread lock, replace it with a new screw connection with thread
lock or secure the old screw connection with medium strength thread locker (e.g.Loctite®241).
CAUTION
Improper use of self-locking nuts
Tipping, falling over of the user due to screw connections coming loose
► Always replace self-locking nuts with new self-locking nuts after disassembly.
CAUTION
Exposed pinch points
Crushing, pinching due to incorrect handling
► When folding the mobility base for seating shells out or together, only grip by the specified components.
CAUTION
Sudden extension of gas compression springs
Impacts, pinching, crushing due to incorrect handling
► The gas compression springs must be fully extended when carrying out any work (seat tilt released, seat in the
neutral horizontal position).
► Never operate the release lever for the seat tilt when screw connections are loosened or when working on the
product.
► Secure the release lever for the seat tilt during all work to avoid operating it unintentionally.
CAUTION
Incorrect air pressure
Uncontrolled driving characteristics, falling, tyre rupture due to incorrect inflation
► Maintain sufficient air pressure in pneumatic tyres. Do not exceed the permitted specifications when filling the
tyres (see Page31).
► Do not use the product with over/under-inflated or unequally inflated tyres.
► Note that a single tyre with low air pressure can lead to uncontrolled driving characteristics.
► Note that low pressure of the rear wheels / drive wheels can reduce the braking force of the knee lever wheel
lock.
CAUTION
Defective tyres
Accidents/falling due to poor traction, reduced braking force or lack of manoeuvrability
► Ensure that the tyres have sufficient tread depth.
► Ensure that the knee lever wheel lock is properly adjusted (approx. 5mm gap to the tyres, technical changes
reserved).
