1-3. Preventive Maintenance Procedures
The following procedures should be done semi-
annually or sooner as needed.
a. Lighthead top cover should be removed and
any accumulation of dust or lint removed.
b. Check the focus drive mechanism for proper
operation and lubrication. Lubricate the drive
gears with lithium grease and all pivot points with
a lightweight oil as necessary.
c. All attaching hardware (screws, nuts, etc.)
should be physically checked for tightness. Any
missing hardware MUST be replaced.
WARNING
Apply LOC-TITE to any replacement
or loose vertical support tube attach-
ing screws.
d. Rotate the radial arm assemblies around the
ceiling mount to check the slip ring/brush block as-
semblies. With electrical power "ON", if the lights
become intermittent or go out, check and repair or
replace the brush block or slip ring as necessary.
e. Check the remaining slip ring/brush block
assemblies by raising, lowering, and rotating the
lighthead through its full range of motion. With
electrical power "ON", if the lights become inter-
mittent or go out, check and repair or replace the
appropriate brush block or slip ring as necessary.
f. Check all fixture rotation axes for proper ad-
justment. Adjust as necessary using applicable
adjustment procedures from the adjustment section
of this manual (Section 2).
