Maintenance
• Check wet cup TSL level daily.
• Do not overtighten packing nut/wet cup. Throat
u-cup is not adjustable.
• Inspect fluid inlet strainer screens daily, see below.
• Grease circulation valves weekly with Fusion
grease (117773).
• Inspect ISO lubricant level and condition daily, see
page 36. Refill or replace as needed.
• Keep component A from exposure to moisture in
atmosphere, to prevent crystallization.
• Clean gun mix chamber ports regularly. See gun
manual.
• Clean gun check valve screens regularly. See gun
manual.
• Use compressed air to prevent dust buildup on
control boards, fan, motor (under shield), and
hydraulic oil coolers.
• Keep vent holes on bottom of electrical cabinet
open.
Fluid Inlet Strainer Screen
The inlet strainers filter out particles that can plug the
pump inlet check valves. Inspect the screens daily as
part of the startup routine, and clean as required.
Use clean chemicals and follow proper storage, transfer,
and operating procedures, to minimize contamination of
the A-side screen.
NOTE: Clean the A-side screen only during daily
startup. This minimizes moisture contamination by
immediately flushing out any isocyanate residue at the
start of dispensing operations.
1. Close the fluid inlet valve at the pump inlet and shut
off the appropriate feed pump. This prevents
material from being pumped while cleaning the
screen.
2. Place a container under the strainer manifold (59d)
to catch fluid. Remove the strainer plug (59j).
3. Remove the screen (59g) from the strainer
manifold. Thoroughly flush the screen with
compatible solvent and shake it dry. Inspect the
screen. If more than 25% of the mesh is blocked,
replace the screen. Inspect the gasket (59h) and
replace as required.
4. Ensure the pipe plug (59k) is screwed into the
strainer plug (59j). Install the strainer plug with the
screen (59g) and gasket (59h) in place and tighten.
Do not overtighten. Let the gasket make the seal.
5. Open the fluid inlet valve, ensure that there are no
leaks, and wipe the equipment clean. Proceed with
operation.
