CLEANING & INSPECTING THE GENERATOR
Use a vacuum cleaner or dry low pressure compressed air
(regulated at 25-35 PSI) to clean the generator periodically.
WARNING: Equipment Damage
DO NOT CLEAN THE GENERATOR WHILE IT IS RUNNING.
Proceed as follows:
1. Remove ventilated control box cover. Vacuum or blow vents
and screen clear of dust or debris. Wash them down with
cleaning solvent if necessary.
2. Remove cooling fan shroud. Vacuum or blow dust from
screen and fan blades. Wipe them off with cleaning solvent if
necessary.
3. Vacuum or blow dust and other debris from inside genera-
tor and control box.
4. With panel cover removed, inspect the wiring for correct
routing, fraying insulation, and secure connections.
5. Replace panel cover and cooling fan shroud.
GENERATOR STORAGE
Before storing the generator, apply a heavy coat of grease to
the splined input shaft. Store the generator in a sheltered
area, where it is protected against snow, rain, and excessive
dust.
