MAINTENANCE
LEGEND SE 980059 07/23/02 4-6
PRESSURE REGULATOR
Lubricate the o-rings every 100 hours. Use o-ring
lubricant Part #05-008035.
For the procedure, see the "General Service
Adjustments” section in this manual for details.
VACUUM HOSES
To assure maximum hose life, we recommend that
the hoses be washed out with clean water at the end
of each working day.
CATALYTIC AIR PUMP
Check and/or replace the air pump every 1500
hours. When replacing, it will also be necessary to
replace the air pump pulley.
TEMPERATURE SOLENOID
Remove hard water deposits from the temperature
solenoid every 200 hours or as often as required.
For the procedure, see the “General Service
Adjustments” section in this manual.
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.
