WARNING: ELECTRICAL SHOCK
HAZARD — Before inspecting or
cleaning inside cabinet, turn OFF
and remove fuses of disconnect
switch (supplying AC power to
charger), disconnect battery, and
check for voltage on capacitors.
Discharge through insulated
screwdriver if there is any reading.

Inspection And Cleaning

For uninterrupted, satisfactory service from this
charger, it's necessary to keep unit clean, dry, and
well ventilated. At least every three months, or more
often as necessary, wipe and blow out all dirt from
unit's interior components, with clean, dry air of not
over 25 psi (172 kPa) pressure. Use a hand bellows
if compressed air isn't available.
Check and tighten all electrical connections as
necessary to eliminate unnecessary losses and to
avoid subsequent trouble from overheating or open
circuits. Check for broken wiring or damaged
Insulation on wiring.
WARNING: ELECTRICAL SHOCK
HAZARD — Failure to keep internal
parts clean and dry may allow
transformer (s) to short out,
causing secondary circuits to
carry dangerously high voltage.
Be sure to replace all charger cabinet panels after
any servicing, to assure proper flow of cooling air
through unit and to protect internal components.
WARNING: ELECTRICAL SHOCK
HAZARD — All cabinet panels must
be replaced to protect personnel from
contact with hazardous voltages.

Lubrication

None required.

Charging Rate Adjustment

Although it is normally not required, the charging rate
can be adjusted to accommodate unusually high or low
AC power line voltages, unusually high or low ambient
temperatures, or aged battery.
A rate adjustment is necessary if battery consumes
more water than normal or if its specific gravity after a
normal (daily) charge is not within 10 points of its
gravity after a weekend (equalizing) charge.
CAUTION: Before adjusting charging
rate, make sure that bad connections
or damage to charger isn't affecting
charging process. Also make sure
proper charging procedure has been
followed (thoroughly read Operation
chapter of this manual).
WARNING: ELECTRICAL SHOCK
HAZARD — Before adjusting charging
rate, turn OFF and remove fuses of
disconnect switch (supplying AC power
to charger), disconnect battery, and
check for voltage on capacitors.
Discharge through insulated screwdriver
if there is any reading.
