Regular cleaning of the fixture is most important to keep a good perfomance over a long
period of time. Especially removing dust and grease from the inside as well as cleaning the
fans ensures reliable perfomance of the Varyscan.
Open the top cover of the head and remove the base plate of the base by loosening the
screws. Use a brush and a vacuum cleaner to remove dust from the inside. Make sure not
to bend or damage the mechanical and electorical parts inside of the fixture.
Incompetend performace of the maintenance will invalidate the warrany claims. Consult
qualified service personnel.

WARNING: Disconnect fixture from mains, and allow
hot lamp to cool down for at least 30 minutes!
For a maximum light output the optical system has to be cleaned from time to time.
Loosen the screws holding the top cover of the head and remove the top cover.
Remove lamp before cleaning the optical parts of the fixture.
Use a soft cloth and gently whipe reflector, lenses and colour filters. You also may
use a pair of tweezers and a regular glass cleaner.

4.3 Lubrication of rotating gobos

WARNING: Disconnect fixture from mains, and allow
hot lamp to cool down for at least 30 minutes!
Once or twice a year the rotating gobos have to be lubricated with JB-lighting special
oil. Do not use any other lubricant, as it might not stand the heat and cause serious
damage.
To lubricate the gobos turn the tooth gears by hand and put 2 to 3 drops of oil between
the brass gear wheel and the brass plate.
