• Disconnect the negative (-) terminal on the battery.
• Attach a “DO NOT START” sign to the control panel. This will notify everyone the unit is being serviced and
will reduce the chance of someone inadvertently trying to start the unit.
• If the unit is connected to a remote start or transfer switch, make sure the remote switch is also off and tagged.
• Never wash the unit with a high pressure hose or with any kind of power washer.
• Never wash the engine block or fuel tank with a power washer or steam cleaner. Water may enter the cabinet
and collect in the generator windings or other electrical parts causing damage.
• If the unit is stored outside, check for water inside the cabinet and generator before each use. If wet, dry the
unit thoroughly before starting.
