Be sure to memorize location of individual parts when
disassembling generator so that generator can be
reassembled correctly. Tag disassembled part with
necessary information to facilitate easier and smoother
reassembly.
For more convenience, divide parts into several groups
and store them in boxes.
To prevent screws from being misplaced or installed
incorrectly, replace them temporarily to their original
position.
Handle disassembled parts with care; clean them before
reassembly using a neutral cleaning fl uid.
Remove battery before disassembling generator.
(Electric start models).
Be sure to attach foam rubber linings inside covers on
their original position when reassembling generator.
When deformation or damage of foam rubber lining is
found, replace it with new part. Failure to do so will result
in poor performance and durability of generator.
Tie wires and fuel hoses using cable ties as they were in
original confi guration.
