BATTERY
Dangerous Acid, Explosive Gases!
Batteries contain sulfuric acid. To prevent acid
burns, avoid contact with skin, eyes and
clothing. Batteries produce explosive hydrogen
gas while being charged. To prevent a fire or
explosion, charge batteries only in well
ventilated areas. Keep sparks, open flames, and
other sources of ignition away from the battery
at all times.
Keep batteries out of the reach of children.
Remove all jewelry when servicing batteries.
Before disconnecting the negative (-) ground
cable, make sure all switches are OFF. If ON, a
spark will occur at the ground cable terminal
which could cause an explosion if hydrogen gas
or gasoline vapors are present. When
disconnecting the battery, ALWAYS disconnect
the negative (-) terminal FIRST.
1. Check the fluid level in the battery every 25
hours or once a week. If low, fill to the
recommended level with distilled water ONLY.
NOTE: DO NOT overfill the battery. Poor
performance or early failure due to loss of
electrolyte will result.
2. Keep the cables, terminals, and external
surfaces of the battery clean. A buildup of
corrosive acid or grime on the external surfaces
can cause the battery to self-discharge. Self-
discharge occurs rapidly when moisture is
present.
The battery terminals should be cleaned every
100 hours to prevent corrosion build-up. Wash
the cables, terminals and external surfaces with
a mild baking soda and water solution. Rinse
thoroughly with clear water.
DO NOT allow the baking soda to enter the
battery cells as this will destroy the
electrolyte.
ENGINE EXHAUST HEAT EXCHANGER
If the engine and/or air pump are not properly
maintained, the exhaust gases may deposit carbon
on the outside of the heat exchanger coil and affect
the cleaning solution temperature and damage the
catalytic converter. If this condition exists, remove
the heat exchanger from the unit and clean the
carbon off the coil. This may be done by taking it to
a radiator dealer and having it boiled out. The
catalytic converter must be completely removed
before cleaning carbon deposits or damage may
result.
Proper maintenance of the unit, such as regular
tune-ups, proper fuel, and a properly operating air
pump will help prevent carbon build-up on the coil
and increase the life of the unit.
Using A212 ULTRA CLEAN INDUSTRIAL
CLEANER or A217-1 ULTRAPAC RENO-VATE will
also greatly enhance the removal of carbon
deposits. Soak the coil and casing ONLY, NEVER
soak the catalytic converter core.
VACUUM EXHAUST HEAT EXCHANGER
Removing and cleaning the vacuum exhaust pre-
heater cores is recommended as needed or if the
unit was operated with the vacuum inlet filter
damaged, removed, or improperly installed. Pull out
the core and remove all debris, being careful not to
drive debris deeper into the core. We recommend
removing the debris with water by either sub-
merging the core and moving it back and forth until
the debris loosens and falls off or by spraying the
debris out of the core. Allow the core to dry before
reinstalling.
