Batteries
the nozzle charging operates on two 9-volt rechargeable batteries
which are located in the base of the spray gun. in average conditions,
the batteries will last 10 to15 hours of operation on a charge. they
should be recharged when the charging indicator on top of the spray
gun shell doesn’t glow when air is going through the spraygun.
after approximately 800 to 1000 hours of service the battery pack will
no longer be able to hold an adequate charge and will need to be re-
placed. replace with nickel-hydride rechargeable batteries. Order the
MBP’s replacement battery pack from ess.
To change the batteries:
1. unscrew the two 6-32 x 1/2” Phillips head machine screws
which hold the battery cover in place.
2. while holding the leads in one hand, gently disconnect the
batteries from the leads. Be careful not to tear the leads off
the wires or to tear the lead wires out of the power supply.

4. replace the battery cover. screw the two 6-32 x 1/2” Phillips
head machine screws back in to secure the battery cover.
