Over time, normal engine operation leads to wear in
the engine valve train which decreases generator output.
To restore generator output, it is necessary to check and
adjust the engine valve lash at regular intervals
throughout the life of the engine. However, proper valve
lash adjustments require specialized training and tools.
Adjustment by persons unfamiliar with the procedure can
cause damage to the engine not covered under warranty.
Contact an authorized generator dealer for assistance in
locating qualified service personnel.
Avoid explosive and potentially lethal fuel leaks by
inspecting the complete generator fuel supply system at
intervals no greater than those listed in the Maintenance
Table on page 25. Visually inspect all hoses for cracks,
splits, or brittleness and replace hoses that show these
or other signs of wear. Check all connections for
tightness and cracks, replacing any broken fittings or
clamps. Check all connections for leaks, while the
generator is running, using approved equipment and
methods. DO NOT use a flame to check for leaks.
