Servicing Instructions Work Chair
Servicing, inspection, and repairs may only be carried out by personnel who possess the relevant
technical knowledge of the product in order to maintain the validity of the CE mark. No-one may sit
in the product whilst it is being serviced.
Customised products can be restored if the relevant parts are replaced with original parts from
Eurovema and the restoration is carried out by an authorised technician. A new label showing the
CE mark can be ordered.
During servicing, it is important that a visual inspection of the product's metal components is carried
out in order to rule out the presence of damage or cracks that may impact the safety of the product.
Check brakes, seat functions, tilt and lift, attachment, and function.
Any defects identified must be addressed. If parts need to be replaced, only Eurovema original
parts must be used - except in the case of screws and nuts, where replacements of the right model,
length, and grade are to be sourced.
Instructions about how to fit/remove and adjust components can be found on our website in the
section Assembly Instructions.
Instructions in respect of batteries and electronics can also be found on the website in the section
