Operation
is a switchmode taper charger and can remain connected to the Flexi Pro Sprayer
for extended periods (months) to maintain the battery charge when the sprayer
is not being used. Do not store battery in a discharged state. Connect the charger
before storing sprayer. The red light on the battery charger indicates that the battery
charge is low and the charger is operating in the charging mode. The green light on
the charger indicates the battery is fully charged & the charger has switched to the
maintenance mode.
Warning: Old Style Wall Chargers (NM4108 & NM4108A sold before September
2008) can only be used for a maximum of 12 hours. Overheating of the battery will
occur with longer charging time, with the result being reduced battery life or, with
extreme cases, battery failure. If you are unsure of which charger you have contact
Hydro-Force for assistance in identifying your charger.

chargers is required to get the maximum use from the Flexi Pro battery.
The NM4132 Car Charger is included with the Flexi Pro Sprayer. It can be plugged
into the vehicle cigarette lighter or accessory power outlet and connected to the
Flexi Pro Sprayer to “top-o” the battery charge between jobs. The vehicle must be
running to produce the voltage required for proper charging. The NM4118 Adapter

Pro Car Charger directly to your truckmount or van battery for charging. The
truckmount or vehicle must be running to produce the voltage required for proper
charging.
The NM4130 Wall Charger is included with the Flexi Pro Sprayer. This charger is
plugged into an 110v wall outlet and connected to the Flexi Pro Sprayer when
longer charging times are required to fully charge the battery. A heavily discharged
