CHARGING THE BATTERY PACK
UNPACKING & INSPECTION
The OptimAir MM 2K consists of the
following components:
motor-blower
battery pack
support belt
charger
cable
facepiece
storage plug
filter
Thoroughly inspect all components
of the respirator before the device is
used. Read and observe all NIOSH
approval limitations as they apply to
using the OptimAir MM 2K.
Do not drop the OptimAir MM 2K.
The battery pack can be damaged by
impact. The case can be cracked and
could allow water into the pack. If
the unit is dropped, inspect the case
for cracks. If the motor blower no
longer operates from the compro-
mised battery pack, the battery pack
must be replaced.
The motor-blower housing can be
damaged by impact. The blower
impeller can be loosened or the
motor shaft can be bent. If the unit is
dropped, check the case for cracks.
Listen closely to the sound of the
motor. If the impeller binds or rattles,
or if air output is reduced, the entire
motor-blower must be replaced.
CHARGING THE BATTERY PACK
The battery pack must be fully charged
before the respirator is first used. Use
only the P/N 10023483 battery charger
from MSA. Other chargers can damage
the battery due to internal wiring differ-
ences or incorrect charging rates.
The battery pack should be stored at a
temperature range of 50°F to 85°F. If
the battery pack has been stored in a
“fully charged” condition for more than
one week, the battery pack should be
charged until a full charge is indicated.
Do not charge the battery pack
where there are explosive concentra-
tions of combustible gases, vapors,
or mists. An explosion or fire can
result. Replace the charger if the
cord is damaged or worn, or if the
case is cracked or distorted. Do not
use a damaged charger. Doing so can
result in serious personal injury or
death, or create a fire hazard.
1. Line up the key in
the charger cable
plug with the slot
in the female con-
nector on the bat-
tery pack.
