SECTION 8. SERVICING

1 General

This section describes the various servicing points for your S-58. Servicing includes normal servicing such as topping off of fluids, and refueling the aircraft.

2 Service Points

This section describes all the fluid, pressure and battery servicing points in the S-58. Each fluid filler point has a sightglass to see the current fluid level, and a cap you can click to add fluid.

Engine Oil - Sightglass and filler cap located on forward end of each engine. Click cap to add 1 quart of fluid. Maximum capacity is 10 quarts per engine.	APU Oil - Sightglass and filler cap located on side of the APU unit. Click cap to add 1 quart of fluid. Maximum capacity is 1.8 quarts	Main Transmission Fluid - Sightglass and filler cap located on the left side of the main transmission. Click cap to add 4 quarts of transmission fluid. Maximum capacity is 44 quarts.	Mid-Transmission Fluid - Sightglass and filler cap located behind access panel at base of vertical stabilizer. Click cap to add 1 quart of fluid. Maximum capacity is 0.8 quarts.
Tail-Transmission Fluid - Sightglass and filler cap located behind access panel at top of vertical stabilizer. Click cap to add 1 quart of fluid. Maximum capacity is 1.6 quarts.	Primary and Auxiliary Hydraulic Fluid - Sightglass and filler caps on reservoirs located behind the main transmission. The primary reservoir is on the left, and the auxiliary reservoir is on the right. Click filler cap to add 1 quart of fluid. Maximum capacity is 1.8 quarts.	Utility Hydraulic Fluid - Sightglass and filler caps on reservoir located behind the main transmission. Click filler cap to add 1 quart of fluid. Maximum capacity is 5.04 quarts.	APU Accumulator - Located on right side of engine compartment behind right-side transmission access door. If indicated pressure is below 3000 psi, use hand pump in cabin to repressurize.
Fire Extinguisher - Two bottles for the engines and one for the APU are located behind the main transmission. If indicated pressure is below 1000 psi, replace.	Air Bottle - Located on right side of aircraft in engine compartment between engine and transmission access doors. If indicated pressure is below 1500 psi, replace.	Battery - Located behind an access door on nose of aircraft. Replace if battery fails to charge.

3 Fluid Types

Main Transmission	20 qt.
Intermediate Gear box	2 qt.
T/R Transmission	3 qt.
Primary Servo Hydraulic	2 qt.
Auxiliary Servo Hydraulic	2 qt.

5 Fuel

5.1 Fuel Type

The S-58 is designed to operate on 100LL fuel. When refueling with KellyFuel 3.0 or later, care must be taken to use the correct fuel type. If the incorrect fuel type is used, the fuel in that tank will be tainted, and operating the engine with tainted fuel will cause engine damage and potentially failure. If a tank is accidentally filled with the wrong type of fuel, the tank must be completely emptied to flush it of all contaminant. The tanks can be flushed through the @Cheat menus by setting the fuel amount to 0.

5.1.1 Fuel Capacities

Tank	Capacity	Feeds
Forward Tank	103.4 gal.	Feeds engine
Center Tank	70 gal.	Feeds forward tank
Aft Tank	92 gal.	Feeds center tank

5.2 Gravity Refueling

Figure 1: Gravity Refueling Ports

Gravity refueling ports are located on the left side of the aircraft in front of the left sponson. The forward auxiliary and tank fillers are located behind separate panel doors, while the aft auxiliary and main tank fillers are located behind a shared panel door. To refuel a tank through the gravity refuel system, the panel door must be open and the tank cap must be removed by clicking on them. Tanks can be filled using either KellyFuel or by using the "refuel" chat command.

The front strut can be used as a ground point while refueling. Always properly ground your aircraft before fueling to avoid a static discharge from sparking a potential fuel fire.

5.3 KellyFuel

To use the KellyFuel 3.0 pump to service your aircraft, use the following procedure to prepare aircraft for fueling:

1. Park aircraft within 20m of pump.
2. Click pump. Select aircraft by tail number.
3. Select tank on aircraft to be filled.
4. Open access door and cap for that tank.
5. Click ground wire spool near 100LL side of pump to attach ground wire to nosewheel.
6. Click on fuel hose insert nozzle into filler.

To Fuel Aircraft:

1. Press ENT on keypad to verify it has been grounded
2. Click the credit card reader to "read" your credit card (RP Only)
3. Select 1 for 100LL Fuel
4. Enter the maximum number of gallons, then ENT
5. Reset the meter by clicking the knob on the side
6. Turn the switch next to the pump on the 100LL side to ON
7. Wait for fueling to complete. Fueling will stop when requested number of gallons have been added, the tank is full, or you turn the fuel switch to OFF.
8. Press either 1 to fuel another tank, or 2 to end fueling.
