Battery Safety
WARNING
!
As a battery is being charged, an explosive gas mixture
forms within and around each cell. If the area is not prop-
erly ventilated, this explosive gas can remain in or around
the battery for several hours after charging. Be sure there
are no open flames or sparks in the charging area. An
open flame or spark can ignite this gas, resulting in seri-
ous damage or injury.
WARNING
!
Battery electrolyte is a solution of sulfuric acid and water.
Battery acid causes burns. Should any electrolyte come in
contact with clothing or skin, flush the area immediately
with cold water. Should the solution get on your face or in
the eyes, flush the area with cold water and receive medi-
cal attention immediately.
• Read, understand, and fol-
low procedures, recommen-
dations and specifications in
the battery and battery
charger manuals from the
supplier.
• Wear personal protective
equipment to protect eyes,
face, and skin when check-
ing, handling, or filling batter-
ies. This equipment includes
goggles or face shield, rubber
gloves (with or without arm
shields), and a rubber apron.

1-7
Safety Regulations
• Make sure a shower and eye-
wash station are nearby in
case there is an accident.
• A battery gives off explosive
gases. Never smoke, use an
open flame, or use anything
that gives off sparks near a
battery.
• Keep the charger area well-
ventilated to avoid hydrogen
gas concentration.
• Turn the key switch off before
disconnecting the battery
from the truck at the battery
connector. Do NOT break live
circuits at the battery termi-
nals. A spark often occurs at
the point where a live circuit
is broken.

1-8
Safety Regulations
• Do NOT lay tools or metal
objects on top of the battery.
A short circuit or explosion
could result.
• Keep batteries clean. Corrosion causes shorts to the frame
and possibly sparks.
• Keep plugs, terminals, cables, and receptacles in good con-
dition to avoid shorts and sparks.
• Keep filler plugs firmly in place at all times except when the
electrolyte level is checked, when water is added to the
cells, or when the specific gravity is checked.
• Make sure vent holes in filler plugs are open to allow gas to
escape from the cells.
• Do NOT allow cleaning solution, dirt, or any foreign matter to
enter the cell.
• Make sure to install the cor-
rect size battery. A smaller or
lighter weight battery could
seriously affect truck stability.
See the truck’s specification
(data) plate for more informa-
tion.

1-9
Safety Regulations
• Never plug a battery charger
into the truck’s battery con-
nector. Plug the battery
charger into the battery con-
nector from the battery.
• Follow the charging proce-
dures in the "Battery Instruc-
tion Manual" and in the
"Battery Charger Instruction
Manual".
