11.4 Maintenance work on mounted hose reel
A visual inspection of the
¿ tted hoses and couplings is to be carried out after every use
or every six months. Components showing obvious signs of damage or leaks must be
replaced. If screwed connections start to leak, check whether they are tight
¿ rst of all. If the
leak continues after the screwed connection has been tightened, the screwed connection is
defective and must be replaced.
Hose lines will age over time and must be replaced according to statutory regulations.
If there are no applicable statutory regulations, the hoses must be replaced after 10 years
at the latest. (Read the separate operating instructions for the hoses.)
