PERIODIC MAINTENANCE AND LUBRICATION
MOTOR GENERATOR
MAINTENANCE INTERVALS
Regularly scheduled maintenance is the key to
lower operating costs and longer service life for the
unit . The following schedule (figure 1) can be used
as a guide. However, actual operating conditions un-
der which a unit is run should be the determining
factor in establishing a maintenance schedule . When
operating in very dusty or dirty conditions, some of
the service periods may have to be reduced. Check
the crankcase oil, the filters, etc., frequently until the
proper service time periods can be established .
Additional information about the items on this
schedule may be found later in this section.
LIVING AREA WATER PUMP BELT
Check the living area water pump belt for wear
and adjust tension as necessary every 3 months or
3,000 vehicle miles, whichever occurs first . See "Liv
ing Area Water System" Section 24J for adjusting
information .
The MotorHome may be stored for considerable
lengths of time provided the following steps are per-
formed :
1 . SHORT TERM STORAGE - UP TO 60
DAYS AND ABOVE 32° F. (0°C .)
a. Fill fuel tanks to reduce excessive build-up of
moisture in the fuel tanks.
b. Park MotorHome as level as possible, end for
end and side to side .
c. Wash MotorHome. If exposed to road salts the
exterior and underside should be thoroughly washed
and flushed.
d. Remove all perishables, leave refrigerator door
open . Be sure controls are turned off.
e. Ventilate the living area, drawers, cabinets,
closets,etc .
f. Drain the holding tank, toilet and living area
water system as described earlier in this section. Be
sure the water pump and water heater are turned off.
VEHICLE STORAGE
WATER TANK FILTER
The water tank filter, which is located in the
water compartment, is transparent and should be
checked periodically and cleaned annually . A helpful
sign that filter is dirty is when the transparent filter
has become discolored . See "Living Area Water Sys-
tem" Section 24J for filter replacement procedure.
WINTERIZATION
When traveling in winter it is recommended that
the water tank not be filled until the destination is
reached. This will ensure that the vehicle has
thoroughly warmed up . The water and holding tank
systems should be drained before leaving for home .
Also, an approved plastic pipe non-toxic, non-
flammable antifreeze should be put in the sink and
shower traps. If equipped with a recirculating toilet
the standard winterization is to replace one-half of
the charge water with an approved plastic pipe non-
toxic, non-flammable antifreeze . This antifreeze ad-
ded to the holding tank will help keep the tank
contents from freezing .
See "Vehicle Storage" for additional informa-
tion .
g. Turn off LP gas at tank valve .
h. Make sure range/oven and furnace manual
valve and thermostat are set at "OFF," range/oven
burners at "OFF," oven at "PILOT OFF" and
gas/electric refrigerator control at "GAS OFF."
i. Plug or tape all drains to retard evaporation of
residual moisture in drain traps.
j. Tape over vents to prevent insects from enter-
ing. Be sure to remove tape before operating LP gas
appliances to help avoid poisoning by carbon monox-
ide.
k. Check MotorHome weekly to ensure that un-
desirable conditions are not forming (water seepage,
mold, odors, etc.) . Household air deodorizers or
disinfectants in aerosol cans may be used as required,
however, do not spray directly on any surface.
1. Maintain tire pressure of 60 psi.
m. Crack one window for ventilation, close all
others as well as roof vents.
n. Check batteries (main, auxiliary and motor
