MAINTENANCE
A complete "A" PILOTAIR Valve should be
kept in stock at all times for each four valves in
service. Schedule the maintenance periods so that
complete units can be rotated. The replaced unit

delays.

is easily disassembled after retaining ring (2) has
been removed. Clean all parts with a non-flam-
mable solvent and wash all rubber parts with soap
and water. Rinse the parts well and dry with a
low pressure air jet.
Examine all parts for wear noting particularly
the condition of the
vO"
rings and inlet valve.
The worn parts or tL, ose that may permit excess
leakage before the next maintenance period should
be replaced.
Lubricate all metal to metal surfaces with a
thin film of No. 107 Lubriplate and all rubber parts
with Cosmolube grease. Equivalent lubricants to
those
recommended can be used.
