which win reduce your chance Of
trouble to q minimum. II you Will
observe the following rules which
become very simsple, after being
practiced for a while, you can avoid
90 per cent Of common battery
troubles.
First-Examine the battery at
least once O week during warm
weather, under normal running con-
ditions and at least twice Q week
when touring from 100 to 200 miles
per day. ...s
Before removing the vent plugs.
brush all dust and dirt Off the top
of the battery 40 that none VIII
fall into the cells when adding
water. See that water level does
not fall below the top OF plates.
rhe proper level varies slightly IN
different makes of batteries. How
ever. a safe standard IL to have the
water one.fourth inch above the
top of plates. Do not I'LL too full.
The level should never be higher
than one-sighth inch below the bot
tom rim of plug holes. II the wa
ter level Ia too high. 1t will slop out
through the small vent holes In
Mug. then over the top OF the bat
terry, and may possibly. form q cir
cuit tiischarging through the frame.
Aftsr filling to proper level. replace
the plugs and wipe the top OF bat
terry dry with rag.
In filling the battery with water.
use distilled water only from glass

not use metal cups or tunnels.
Second: In order 70 avoid the IN

Fourth. Always make the hydrom-

taken.
sixth. Do not permit anyone other
