5.1 Planned Maintenance
The PTR-200-PRL is designed for a production environment to give trouble-free operation provided
normal planned maintenance is adhered to. Maintenance and repair procedures should be performed
only by trained personnel. Improper service and/or repair could result in the safety features being
disabled and can also lead to damage that will not be covered under warranty.

5.2 Inspecting the Fiber Holding Blocks
The Fiber Holding Blocks (FHB’s) should be inspected daily for debris and/or damage, which may prevent
the tops from closing properly and the fiber from being clamped fully. It is particularly important to make
sure that the bottom insert V-groove surfaces and the top insert clamping surfaces are free of debris and
oils. This will help to ensure that the fiber will not break or slip during tensioning. Cleaning the metal
insert surfaces is best accomplished using a cotton-tipped applicator wetted with acetone or alcohol. For
embedded debris, a soft cleaning brush may be used. Cleaning the rubber insert surfaces is best
accomplished using a cotton-tipped applicator wetted with alcohol. Do not use acetone as this will dry out
the rubber causing it to become brittle and crack.
5.3 Inspecting and Cleaning the Die
The die of the recoat head should be inspected daily for debris and/or damage which may result in sub-
optimum recoat performance.
The recoat head assembly contains two die sets (left and right), each with a semi-circular channel running
longitudinally down the center of their mating surfaces. When closed, the die form a circular mold cavity
around the section of fiber to be recoated. In order for the die to mate flush together, they must be free of
all dirt and/or coating particles.
The die should be cleaned with a cotton tipped applicator wetted with NMP. NMP is the solvent for
PI2525 and can be used to soften and lift away any residual recoat material. Wipe the top and both sides
of the die using very light pressure only. Wipe both the left and right and top and bottom of the die set. If
