The needle 
 may sometimes touch the product being measured or the needle may suck 
fluid from the packaging from which the measurement is taken. If this happens, it will be 
necessary to replace both the needle and the filter.
If there is any dirt or fluid in the measuring gas hose 
, it should be replaced or cleaned 
using dry compressed air.
All of the parts can be ordered (and replaced) separately or as a complete kit.
See "Consumable parts and options" on page 56.
