WARNING
NEVER adjust belts with power applied!
Belt tension should be kept as loose as possible while remaining tight enough to drive all
mechanisms. To adjust belt tension, follow procedures in Sections 6.4.1 through 6.4.3.
Do not over-tighten belts. If belts are too tight, projector will not
operate properly, and projector parts will wear prematurely.
