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 attaching
screws.
d. Rotate the radial arm assemblies around the
ceiling mount to check the slip ring/brush block
assemblies. 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 intermit-
tent 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
adjustment. Adjust as necessary using applicable
adjustment procedures from the adjustment sec-
tion of this manual (Section 2).
SECTION I MAINTENANCE
1-1. General
To ensure proper operation and extend the life of
your SKYTRON surgical lighting fixture, the follow-
ing preventive maintenance procedures are rec-
ommended.
NOTE
All repairs should be made using autho-
rized SKYTRON replacement parts.
1-2. Daily Maintenance
Daily or between cases, the lighthead exterior
should be wiped down with a mild cleaning agent
which will not affect the painted or acrylic parts. Do
not apply or spray cleaning agents directly on the
lighthead.
CAUTION
Use of incompatible cleaning agents
will cause damage to the fixture. Avoid
the use of cleaning solutions which
contain high concentrations of alcohol,
ethelene glycol, phenol, iodophors, or
glutaraldehyde based disinfectancts.
Staining, pitting, discoloration and dif-
fuser cracking may occur if these are
used.
•Only dissinfectants and cleaners may be used
that are certified from the manufacturer for com-
patibility with the following materials:
-- Polycarbonate (PC)
-- Polyvinylchloride (PVC)
-- Silicones
•Always consult with the manufacturer of the clean-
ing agent for proper application and use. Always
spot test on an inconspicuous area before use.
•Avoid personal injury. Do not attempt to clean
lighthead unless power is turned off at wall control.
•Avoid using excessive amounts of spray cleaners.
Leakage of fluids into the interior of lighthead may
cause corrosion of electrical components.
