3.1.3 Checking the operation of each valve of head
This section describes the procedure of checking the operation of the blow valve and the cleaning blow
valve of head unit. The head unit is installed 2 types of valves, one is the blow valve blowing by each
shingle head, and the other is the cleaning blow valve blowing powerfully to clean up inside of shaft.
When the valve motion error occurs, it needs to be replaced. See Chapter 5, "3.1 HM head: Replacing the
valves"
c
CAUTION
The cleaning blow exhausts powerful air. The nozzle attached to the head should be detached upon performing the
cleaning blow. If the cleaning blow is performed with the nozzle attached, the nozzle may drop off from head and may be
damaged or lost.
1
Detach all the nozzles from the heads.
When the nozzle station is equipped.
1. Open the [Unit] - [Head] screen.
2. Select any head unit from "Table Select".
3. Press the [Nozzle Change] button. Select
"ALL" for "Head Number" and select "Store
Nozzle" for "Nozzle Type" on the "Nozzle
Change" screen.
4. Press the [OK] button to return all nozzles to
the nozzle station.
n
NOTE
When the machine does not equip the nozzle station,
open the machine safety cover and detach the nozzles by
hand.
