CLEANING AND MAINTENANCE

●
If a projector can't start. Please check if the fuse is blown up. If it does, replace it with a new fuse with same ratings. And the
projector has over-temperature protective device. If the temperature is too high, the protective device will be triggered to shut the
projector off. When it happens, please check if the fans run normally or fan shield is blocked by dust. After the issue is solved,
restart the projector.
The accumulation of oil, smoke and dust on the lens will compromise the light output. Cleaning a projector is very necessary to
ensure a reliable use of it. Cooling fans need to be cleaned every 15days. Internal lens, reflector and hot mirror need to be cleaned
periodically to optimize light output.
Cleaning frequency is to be decided by operations and its environment. Use soft cloth and normal detergent for glass for cleaning
work. It's advised external optical system be cleaned every 20days and internal optical systems every 30/60days. Keep lens clean
and do not touch optical parts with bare hands.
LUBRICATION
●
To ensure smooth movement of gobos and zoom and focus lens, it's advised rotators' bearings and 4 slide rails for zoom and
focus lens be lubricated every 2 months. High quality and high temperature lubricant/grease is advised.
