For maximum lamp operating life:
• Avoid powering the lamp off until it has warmed up for at least 5 minutes.
• Before shutting down power completely, douse the lamp but leave power
applied for a few minutes so that cooling fans can prevent any momentary
lamp temperature increase caused by heat from surrounding components.
Cleaning
The cleaning of external optical lenses must be carried out periodically to
optimize light output. Cleaning schedules for lighting fixtures vary greatly
depending on the operating environment. It is therefore impossible to specify
precise cleaning intervals for the fixture. Environmental factors that may result
in a need for frequent cleaning include:
• Use of smoke or fog machines.
• High airflow rates (near air conditioning vents, for example).
• Presence of cigarette smoke.
• Airborne dust (from stage effects, building structures and fittings or the
natural environment at outdoor events, for example).
If one or more of these factors is present, inspect fixtures within their first 100
hours of operation to see whether cleaning is necessary. Check again at
frequent intervals. This procedure will allow you to assess cleaning
requirements in your particular situation. If in doubt, consult your RUSH by
Martin dealer about a suitable maintenance schedule.
Use gentle pressure only when cleaning, and work in a clean, well-lit area. Do
not use any product that contains solvents or abrasives, as these can cause
surface damage.
To clean the fixture:
1. Disconnect the fixture from power and allow it to cool for at least 10
minutes.
2. Vacuum or gently blow away dust and loose particles from the outside of
the fixture and the air vents at the back and sides of the head and in the
base with low-pressure compressed air.
3. Clean the LED lenses by wiping gently with a soft, clean lint-free cloth
moistened with a weak detergent solution. Do not rub the surface hard: lift
particles off with a soft repeated press. Dry with a soft, clean, lint-free cloth
or low-pressure compressed air. Remove stuck particles with an
unscented tissue or cotton swab moistened with glass cleaner or distilled
water.
