1.2.1 Cleaning the nozzle buffing area
e
1
Remove the nozzle from the head.
Always first press the emergency stop button
and then remove the nozzle from the head.
The machine must be in emergency stop to
ensure safety during work.
2
Clean the slide section.
Apply IPA (isoprophyl alcohol) or ethanol to
the slide section. Push the nozzle tip several
times to repeat the buffing action (spring
action) to clean the slide section. After
cleaning, blow sufficient air to remove IPA or
ethanol.
3
Lubricate the slide section.
Using a precision screwdriver or similar tool
with a pointed tip, apply a small amount of
turbine oil (just enough so that it sinks in) to
the slide section.

4
Check the buffing action (spring
action).
Push the nozzle tip several times to repeat
the buffing action and spread turbine oil.
Use a lint-free cleaning cloth to wipe away
excess oil from around the nozzle.
53302-N5-00
5
Remove excess oil remaining in the
nozzle.
Air blow with the aIr blow tool for
approximately 5 seconds from the nozzle tip
side, and approximately 5 seconds from the
nozzle mounting side. Repeat this process a
few times to remove excess turbine oil
remaining in the nozzle.
n
NOTE
A thin coat of oil is enough to lubricate the slide section.
6
Check that the oil was removed.
Blow air through the nozzle again while
placing commercially-available oil blotting
paper over the opposite end of the nozzle,
and check for residual oil in the nozzle.
n
NOTE
Performing step 5 is usually sufficient to remove oil
remaining in the nozzle. However, if oil still remains then
blow air through the nozzle once again.

7
Return the nozzle to its original
position.
After verifying again that the nozzle is free of
oil, return the nozzle to its original position
(head or nozzle station).

Step 6
Oil will appear after blowing air (first time) for
about 5 seconds from the nozzle tip.
Repeat the air blow for about 5 seconds
each from the nozzle tip and from the
attachment side.
This task is finished when oil no
longer appears.
