4.4.3 Pinspotter Protection During Lane Refinishing (Wood Lanes
Only)
During the resurfacing or refinishing of wood lanes, dust particles and aerosols from
the refinishing agents can settle on operating parts of the pinspotter and cause
serious problems when operations are resumed. To prevent problems, the
following precautionary measures must be observed:
4.4.3.1 Refinishing Wood Lanes
The purpose of this protection is to prevent aerosols from epoxies, urethanes, and
varnishes from depositing on exposed electrical contacts. When cured, these
substances act as electrical insulators making the unit inoperative.
1. Seal all motor ventilating openings using masking tape or plastic wrap.
2. Cover and seal the chassis.
4.4.3.2 Resurfacing Wood Lanes
1. Cover all open gearing, delicate assemblies, and operating surfaces with rags,
newspaper, or plastic. This prevents dust particles from clinging to the
mechanisms, which can cause mechanical binds.
2. Cover any exposed part that has an oily or greasy surface.
3. After resurfacing is complete, all protection except on motors and chassis can be
removed.
4. Wipe down the entire pinspotter with a damp cloth.
5. After the refinishing process is completed AND THE BUILDING IS FREE OF ALL
VAPORS FROM THE REFINISHING AGENTS, motor and chassis protection may be
removed.
NOTE: The sweep assembly may be removed, if necessary, in order to permit the
resurfacing machinery to reach the back of the pin deck area.
