Maintenance

Refer maintenance to qualified technicians. Please disconnect power 
and signal wire before maintaining fixtures.

In order to preserve OBY-3 in good condition, keep the routine 
maintenance by following date.

The Steps are as follows:

The dichroic colour-filters, the metal gobo-wheel, the internal lenses 
and cooling fans should be cleaned with soft brush monthly.

The interior of the fixture should be cleaned at least half-yearly using 
a vacuum-cleaner or an air-jet.
Caution: Be careful not to damage the interior mechanical structures 
or circuits when using the air-jet.

To ensure a proper function and smooth rotation of the gobo-wheel, 
we recommend lubrication in six-month intervals.
Caution: Avoid the damage of interior structures when fixtures 
rotated, do not use excess lubrication.

Due to emit fog frequently, the optical lens and gobos would be oily; 
thus luminosity would be weak. We recommend using moist cloth or a 
trace of detergents to wipe them every two weeks. (Prohibit using the 
detergents consisted of alcohol and solvents.)

Replacing the Fuse

If the fixture does not function, that may be the fuse was burned out. It 
may be time to replace the fuse of same type and specification for 
eliminating this fault.

Remove the electric power and flip the switch to " off "  position before 
replacing the fuse.

Replace the fuse as follows:

Step 1: Unscrew the screw of the fuse holder on the housing  

counterclockwise with appropriate tools.

Step 2: Remove the broken fuse and then replace the new fuse.

Step 3: Reinsert and tighten the screw on the fuse-holder.

Step 4: Turn the power on for test.

Please contact with the dealer if the fixture still cannot work or the fuse 
burns out again.
