GENERAL MAINTENANCE
TIRE INFLATION
For maximum service from the tires on the Cherokee,
keep the tires inflated to the proper pressure of 24 pounds for
the main gear, and 24 pounds for the nose wheel. Interchange
the tires on the main wheels if necessary to produce even wear.
All wheels and tires are balanced before original installation,
and the relationship of the tire, tube and wheel should be
maintained if at all possible. Out of balance wheels can cause
extreme vibration on take-off. In the installation of new
components, it may be necessary to rebalance the wheel with
the tires mounted.
BATTERY SERVICE
Access to the 12 volt battery is through the right rear
baggage compartment panel. The stainless steel box has
a plastic drain tube which is normally closed off with a clamp
and which should be opened occasionally to drain off any accum-
ulation of liquid. The battery should be checked for proper fluid
level, but must not be filled above the baffle plates. A hydro-
meter check should be performed to determine the percent of
charge present in the battery.
If the battery is discharged, charge it before take-off as
three volts are needed to excite the alternator. Recharge start-
ing at a 4 amp rate and finishing with a 2 amp rate. Quick
charges are not recommended.
BRAKE SERVICE
The brake system is filled with MIL-11-5606 (petroleum
base) hydraulic brake fluid. This should be checked at every
100 hour inspection and replenished when necessary by filling
the brake reservoir on the firewall to the indicated level. If
the system as a whole has to be refilled with fluid, this should
