Cleaning A Clogged Tip; Maintenance; Daily Maintenance; Maintaining The Filter Assembly - Speeflo PowerTwin 8900 GH Manual Del Propietário

Cleaning a Clogged Tip

1. Follow the "Pressure Relief Procedure" in the Operation
section of this manual.
2. If the tip clogs, rotate the tip handle 180° until the arrow
on the handle is facing the opposite of the spray direction
and the handle clicks in the reverse position.
3. Trigger the gun once so that the pressure can blow the
clog out. NEVER use the tip in the reverse position for
more than ONE trigger pull at a time. This procedure can
be repeated until the tip is free of clogging.
WARNING
The flow from the spray tip is at very high pressure.
Contact with any body part may be dangerous. Do not
place finger on gun outlet. Do not point the gun at any
person. Never operate the spray gun without the proper
tip guard.

Maintenance

WARNING
Before proceeding, follow the Pressure Relief Procedure
outlined previously in this manual. Additionally, follow all
other warnings to reduce the risk of an injection injury,
injury from moving parts or electric shock. Always unplug
the sprayer before servicing!

Daily Maintenance

Two daily procedures are required for routine operator
maintenance on this unit:
1. Lubricating the upper packings.
2. Cleaning the rock catcher.
Lubricating the Upper Packings
1. Clean out the paint that has
seeped past the upper
packings into the packing oil
reservoir above the fluid
section.
2. Fill the packing oil reservoir 1/2
full with Piston Lube (P/N 700-
925) supplied by the factory.
This will extend packing life.
NOTE: Do not over-fill the
reservoir so that it
overflows and drips
into the paint.
Cleaning the Rock Catcher
1. The rock catcher will clog and
must be cleaned at least once a
day.
2. Loosen the nut that secures the
rock catcher to the siphon tube.
3. Remove the rock catcher from the
bottom of the siphon tube.
4. Clean thoroughly with the
appropriate solvent.
