Main valve
The main valve is precision made and must be treated with great
care so that its performance will not be impaired. The following
rules apply whenever service work is carried out.
1. Protect the valve against moisture and dirt. Take particular
care to avoid dirt entering the connection ports. Also protect
the ports from damage by scratching or bruising. Keep un-
connected ports plugged with plastic plugs or the like.
2. Protect the ends of the spools and covers against blows. The
valve spool may be bent if handled carelessly, and it will then
immediately jam on being used.
