Spray Inspection
(1) Opening the Spray Cock and Checking the
Spray Condition
[1] Inspect the nozzle for clogging due to dust, etc.
[2] Check the open/close condition of the main spray
cock and each spray cock (left nozzle, center
nozzle and right nozzle).
⚫
Long hours of use causes the nozzle plate to wear
and discharge flow rate to increase. When this
happens, replace the nozzle plate.
