6. MAINTENANCE
Because the REDI-LINE generator contains long life bearings and brushes, it is
virtually maintenance free. We recommend that the few maintenance procedures
given below be performed on a periodic basis. Because generator environment and
usage varies with each application, we suggest that initial cleaning and inspection
be performed once a month at first. This period can be extended as experience with
the unit increases.
Cleaning
Wipe down the unit with a shop rag or similar cloth. Be sure that ventilation holes
are not plugged. Clean any electrical connections that have become corroded.
Mounting and Electrical Connections
Inspect mounting hardware for tightness and tighten as necessary. Inspect cable
and battery connections for tightness, and tighten as necessary. Inspect electrical
cables for damage, and replace any that show signs of wear.
Brushes
Inspect brushes periodically to insure uninterrupted service. Brush life expectations
vary based upon the type of tools or appliances you use with the generator. To
avoid damage to the generator, a preventive maintenance inspection interval should
be determined for your application. We recommend initially that you inspect the
brushes after 500 hours of use. Brush length after 500 hours of use will help you
establish an appropriate maintenance schedule. Always clean out brush dust when
inspecting or changing brushes.
Damage to the commutators may occur if the brushes are allowed to wear down
below 0.56-inch minimum length. This minimum length applies to both AC and DC
brushes.
Commutators
When inspecting brushes, check the commutators for wear. If the commutators are
worn or pitted, turning and undercutting is recommended. Return your unit to the
distributor or factory for service. . Usually three sets of brushes can be worn out
before it is necessary to turn the commutators.
