A. Lamp Replacement (See figure 4)
WARNING
To avoid electrical shock hazards, do not replace lamp when power is applied.
1. Remove the dome assembly by grasping the die-cast ring attached to the dome
and turning it counter-clockwise. If difficulty occurs removing the dome assem-
bly, place a screwdriver blade against one of the four bosses on the die-cast ring
attached to the dome. Gently tap the screwdriver handle to loosen the dome
assembly from the housing.
WARNING
To maintain the watertight enclosure, do not damage dome or threads while
disassembling or reassembling the unit. Lubricated threaded joints
exposed for long periods of time may attract small particles of
dirt or other foreign materials. Re-assemble joint
immediately after performing maintenance.
2. Lift the connector from the lamp terminals.
3. Lift the spring clip at the top of the lamp and rotate the curved lamp retainer
toward the front of the lamp. Lift out the lamp.
4. Install the replacement lamp by placing the edge of the lamp into the groove of
the die-cast lampholder. Rotate the lamp so that its prongs point straight up.
5. Rotate the lamp retainer up until the spring clip snaps over the edge of the lamp.
Replace the connector on the lamp terminals.
6. Replace the dome assembly by turning clockwise until it is seated securely against
the gasket.
7. Test light for proper operation.
B. Lubrication
1. Lubricate the lamp shaft bearings with a light machine oil every 12 months or
5000 hours of service, whichever comes first.
2. The worm and worm gear rarely require lubrication. However, if lubrication is
required use a light high quality grease.
3. The motor is equipped with sealed bearings and requires no maintenance.
4. The threaded dome ring joint should be well lubricated with petroleum or a soap-
thickened mineral oil. If corrosive products have accumulated on joints and can-
not readily be removed with solvents, the parts should be discarded and replaced.
