BLOWER MAINTENANCE
Keeping the blower as clean as possible will avoid system
overheating. Overheating will cause lowered production, possible
system failure and shorten the expected life of your FORCE/1. Inspect
blower brushes every three months or 100 hours of use. Replace
brushes when they reach
before the brush stunt touches the commutator. When reassembling,
the lead wires must be isolated from the motor frame and any rotating
parts.
