nameplate rating. The proper installation and use of
a loadbank can prevent loss of capacity and
increased maintenance caused by unburned fuel
due to wet stacking.
If you have a generator set that is already wet
stacked, it is recommended that the load bank be
used in progressive steps outlined below.
1 Assure that the generator set is properly
grounded and connected to the load bank as
instructed by the manufacturer.
2 Set the generator at 240 VAC, 3 - phase.
3 Start using less than 25% of the nameplate
rating until the engine has warmed up.
4 Progressively increase the load as the generator
will allow without shutting down.
5 Continue to run for 20 minutes per step.
6 When you reach 80% of the nameplate rating,
run the generator for a minimum of 45 minutes
or until the exhaust on the unit runs clean.
7 Allow the machine to fully cool down.
8 Start the unit again.
9 Load at 80% for an additional 30 minutes.
A full engine service is recommended after this

Check the Tires and Wheels
Bodily injury hazard. An over-inflated tire can
explode and may cause death or serious injury.
Collision hazard. An excessively worn tire can
cause poor handling and continued use could result
in tire failure.
Tip-over hazard. Do not use temporary flat tire
repair products.
Maintaining the tires and wheels in good condition
is essential to safe operation and good
performance. Tire and/or wheel failure could result
in a machine tip-over. Component damage may
also result if problems are not discovered and
repaired in a timely fashion.
1 Check the tire surface and sidewalls for cuts,
cracks, punctures and uneven or excessive
tread wear. Replace the tire if uneven or
excessive tread wear is found.
2 Check each wheel for damage, bends and
cracks. Replace the wheel if any damage is
found.
Note: Tires and wheels must be replaced with tires
and wheels of the specifications listed.
3 Check each tire with an air pressure gauge and
add air as needed.
4 Check the torque of each lug nut.
