ELECTRICAL SYSTEM
The CherokeeWarrior is equipped with a simple but highly efficient electricalsystemthat
can be easily operated.
The electrical system includes a l4 volt 60 ampere alternator, voltage regulator,
overvoltagerelay, battery contactor and a standard l2 volt 25 ampere hour or an optional l2
volt 35 ampere hour battery. The battery is mounted in a thermoplastic box located
immediately aft of the main spar on the right side of the fuselagebelow the rear passengers
seat.
The voltage regulator and overvoltagerelay are located on the forward left side of the fuselage
behind the instrument panel.
Electrical switches are located on the right center instrument panel, and the circuit
breakersare located on the lower right instrument panel. A rheostat switch on the left side of
the switch panel cotrtrols the optional navigationlights and the radio lights.A similar switch on
the right side of the switch panelcontrolsand dims the optional panellights.The masterswitch,
anti-collision light, landing light and fuel pump are also located on the switch panel and are
controlledby rocker tvpe switches.

Primary electrical power is provided by the 14 volt 60 amp alternator. The alternator
system offers many advantagesover the generatorsystem both in operation and maintenance.
T|e main advantageis full electricalpower output at lower engineRPM. This providesimproved
radio and electricalequipment operation and increasedbattery life by reducingbattery load.
This will make cold weatherstarting easier.
Secondaryelectricalpower is provided by the standardor optiotral battery.
Unlike previous generator systems, the ammeter as installed does not show battery

BRAKE SERVICE
The brake system is filled with MIL-H-5606 (peholeum base) hydraulic brake fluid. The
fluid level should be checkedperiodically or at each 50 hour inspectionand replenishedwhen
necessary.The brake reservoir is located on the upper left side of the fire wall in the engine
compartment. If the entire systemmust be refilled, fill with fluid under pressurefrom the brake
end of the system.This will eliminateair from the system.
No adjustment of brake clearancesis necessary.If after extended servicebrake blocks
becomeexcessivelyworn, they should be replacedwith new segments.
LANDING GEAR SERVICE
The main landing gearsuse Cleveland6.00 x 6 wheels,and the nose gear carriesa Cleveland
5.00 x 5 wheel. All three tires are 4 ply rating, Type III tires with tubes;the main geartires are
6.00 x 6 and the nosegeartire is 5.00 x 5. (SeeTire Inflation, this Section.)
Main wheels are removed by taking off the hub cap, pin, axle nut, and the two bolts
holding the brake segmentin place,after which the wheel slips easilyfrom the axle.
The nosewheel is removedby taking off the axle nut and washerfrom one side,sliding out
the axle rod and plugs, lightly tapping out the axle tube, and then removing the wheel and
spacertubes from betweenthe fork. Wheelsare replacedby reversingthe procedure.
Tires are removed from the wheelsby deflating the tire, removing the through bolts, and
separatingthe wheel halves.
Landing gear oleo struts should be checkedfor proper strut exposureand visible leaks.The
required extensionsfor the struts under normal static load (empty weight of airplane plus full
fuel and oil) are 3.25 inches for the nose gear and 4.50 inches for the main gear. If the strut
exposure is below that required, it should be determined whether air or oil is neededby first
raising the airplane on jacks. Depressthe valve core to allow air to escapefrom the strut housing
chamber. Remove the filler plug and slowly raise the strut to full compression.If the fluid is
then visible up to the bottom of the filler plug hole, only proper extension with air is required.
If fluid is below the bottom of the filler plug hole, oil should be added.Replacethe plug
with the valve core removed.Then attacha clcarplastichoseto the valvestem of the filler plug
and submergethe other end in a containerof hydraulic fluid (MlL-H-5606). Fully compressand
extend the strut several times, thus drawing fluid from the container and expelling air. The
torquie link assembly must be disconnected to let the strut be extended a minimum of l0
inches. (The nose gear torque links need not be disconnected.) DO NOT allow the strut to
extend beyond l2 inches.When air bubbles ceaseto flow through the hose,fully compressthe
strut, remove the f,rller plug, and again check the fluid level. When the fluid level is correct,
disconnect the hose, reinstall the valve core, the filler plug, and the main gear torque linksWith the fluid in the strut housing at the proper level, attach a strut pump to the air valve.
With the airplane on the ground under normal static load, inflate the oleo strut to the proper
strut exposure.

In jacking the airplane for landing gear or other service,two hydraulic jacks and a tail stand
should be used. At least 250 pounds of ballast should be placed on the tailstand before jacking
the airplane. The hydraulic jacks are placed under the jack points on the undersideof the wings,
and the airplane is jacked up until the tail stand can be attachedto the tail skid. After attaching
the tail stand and adding the ballast,the jacking can be continued until the airplaneis at the
desired heieht.
The steering arrns from the rudder pedals to the nose gear are adjusted at the rudder pedals
or at the nose wheel by turning in or out the tlrreaded rod end bearings. Adjustments are
normally made at the forward end of the rods and should be done in such a way that the nose
wheel is in line with the fore and aft axis of the airplane when the rudder pedalsand rudder are
centered.Alignment of the nose wheel can be checkedby pushing the airplaneback and forth
with the rudder centeredto determinethat the plane follows a perfectly straight line.
The turning arc of the nose wheel is 30 degreeseither side of center and is factory adjusted
at stops on the bottom of the forging.The turning radius of the nose wheel is l3 feet.
The rudder bar stops should be carefully adjustedso that the rudder bar reachesits full
traveljust after the rudder hits its stops.This guaranteesthat the rudder will be allowed to move
through its full travel.
PROPELLER SERVICE
The spinner and backing plate should be cleanedand inspected for cracks frequently.
Before each flight the propeller should be inspectedfor nicks, scratches,or corrosion.If found,
they should be repairedas soon as pssibleby a rated mechanic,sincea nick or scratchcausesan
area of increasedstresswhich can lead to serious cracks or the loss of a propeller tip. The back
face of the blades should be painted when necessarywith flat black paint to retard glare. To
prevent corrosion, all zurfaces should be cleaned and waxed periodically.

FUEL REQUIREMENTS
The minimum aviation grade fuel for the PA-28-l5l is 80/87. Shce the use of lower
gradescan causeseriousengine damagein a short period of time, the engine warranty is
invalidatedby the use of lower octanes.
Whenever80187 is not available.the lowest lead l00grade should be used.(SeeFuel
Grade ComparisonChart. below)
The continuous use. more than 257oof the operatingtime. of the higher leadedfuels
can result in increasedengine deposits,both in the combustion chamberand in the engine
oil. It may require increasedspark plug maintenanceand more frequent oil changes.The
frequency of spark plug maintenanceand oil drain periods will be governedby the amount
of lead per gallon and the type of operation. Operation at full rich mixture requiresmore
frequent maintenanceperiods: therefore it is important to use proper approved mixture
leaningprocedures.
Reference Avco Lycoming Service Letter No. Ll85A attached to the Engine
Operators Manual for care, operation and maintenanceof the airplane when using the
higher leadedfuel.

TIRE INFLATION
For maximum servicefrom the tires, keep them inflated to the proper pressures.The main
geartires should be inflated to 24 psi and the nosegearshould be inflated to 30 psi.
Interchangethe tires on the main wheelsif necessaryto produce evenwear. All wheelsand
tires are balancedbefore original installation, and the relationshipof the tire, tube, and wheel
should be maintained if at all possible.Unbalanced wheels can causeextreme vibration on
takeoff. ln the installation of new components,it may be necessaryto rebalancethe wheel with
the tire mounted.
When checkingthe pressure,examinethe tires for wear, cuts, bruises,and slippage.
BATTERY SERVICE
Accessto the l2-volt battery is obtained by raisingthe rear seatand removing the cover of
the battery box. The plasticbattery box has a drain tube which is normally closedoff with a
cap and which should be openedoccasionallyto drain off any accumulationof liquid.
The battery should be checked for proper fluid level. DO NOT fill the battery above the
baffle plates. DO NOT fill the battery with acid - use only water. A hydrometer check will
determine the percent of chargein the battery.
If the battery is not up to charge,rechargestarting at a 4 amp rate and finishing with a 2
amp rate. Quick chargesare ltot recommended.
WINTERIZATION
For winter operation a winterization plate is installedon the inlet opening of the oil
cooler.This plate should be installedwheneverthe ambient temperaturereaches50" F or less.
The plate should be removedand stored in the cockpit when the ambienttemperatureexceeds
