DEPLOYMENT PROCEDURES FOR AIR BAG MODULE
(OUTSIDE OF VEHICLE)
NBRS0018S02Unless the vehicle is being scrapped, deploying the air bag in the
vehicle is not recommended. This may cause damage to the
vehicle interior.
Anchor air bag module bracket [KV99105300 (J41246)] in a vise
secured to a firm foundation during deployment.
Deployment of Driver's Air Bag Module (Outside of
vehicle)
NBRS0018S02011. Make an 8.5 mm (0.335 in) diameter hole in air bag module
bracket [SST: KV99105300 (J41246)] at the position shown in
figure at left.
2. Using wire, secure air bag module to air bag module bracket
[SST: KV99105300 (J41246)] at two places.
CAUTION:
Use wire of at least 1 mm (0.04 in) diameter.
3. Firmly secure air bag module bracket [SST: KV99105300
(J41246)] with air bag module attached, in a vise.

CHARGING THE BATTERYNBSC0003S04CAUTION:
IDo not ªquick chargeº a fully discharged battery.
IKeep the battery away from open flame while it is being
charged.
IWhen connecting the charger, connect the leads first, then
turn on the charger. Do not turn on the charger first, as
this may cause a spark.
IIf battery electrolyte temperature rises above 60ÉC (140ÉF),
stop charging. Always charge battery at a temperature
below 60ÉC (140ÉF).

Do not charge at more than 50 ampere rate.
NOTE:
The ammeter reading on your battery charger will automatically
decrease as the battery charges. This indicates that the voltage of
the battery is increasing normally as the state of charge improves.
The charging amps indicated above refer to initial charge rate.
IIf, after charging, the specific gravity of any two cells varies
more than .050, the battery should be replaced.
