The procedures outlined in this Manual are suggested general operating
procedures. For specic aircraft servicing, follow procedures specied by
your airline.
After Operation
Always unhitch unit on level ground. Block wheels and set brakes
before unhitching.
Service Safety
• Do not clean, adjust or service this unit while it is in motion
• Periodically check tightness of nuts and bolts and check for loose,
worn or misaligned parts. Use only approved replacement parts.
• Any new components installed during repair must include the
current safety signs specied by Stinar Corp.
• Disconnect power to electrical components before servicing or
replacing them
• Perform all work in accordance with authorized standard shop
practices
• To avoid possible injury, be sure tire is deated before removing tire
from rim
• Perform no welding, cutting, patching and such on any load bearing
or supporting structure. If such repairs are necessary, contact the
Engineering Department of Stinar Corporation before making any
alterations.
• Should there be a hydraulic system associated with this unit, always
determine hydraulic oil level and ll tank to the proper level with all
hydraulic-actuating cylinders fully-retracted. Otherwise, damage may

SECTION 1 | GENERAL INFORMATION & OPERATING PROCEDURES
Flush & Fill Cart SFFC-70/2 | 9
The Stinar Flush and Fill Cart, Model SFFC-70/2 is a towable service unit
designed for draining contaminated air vehicle coolant for storage in the
cart and eventual disposal. Heated, ltered and deaerated clean coolant is
then pumped from the service cart into the air vehicle in three modes. There
is a ush mode that eliminates residual contaminated coolant. There is a
ll mode that supplies the aircraft with fresh coolant. The deaerate feature
removes all the gases in the system from the coolant. The ush and ll
cart consists of a coolant tank, waste tank and coolant-dispensing system
mounted on a two-axle trailer. The coolant dispensing system consists of a
electric motor-driven diaphragm pump that supplies coolant through a ll
hose. A bleed hose is also used on the cart.
1.1.1 | Equipment Systems and
Components
The major operating systems and components of the ush and ll cart are
described in the paragraphs below. See Figure 1.1.1 for locations.
1.1.1.1 | Cart Chassis
The ush and ll cart chassis provides a mobile platform for the coolant
tank, coolant-dispensing system and electrical system components. The
chassis consists of a rectangular steel frame with a xed rear axle and a
pivoting front axle assembly. The front axle assembly includes a tow bar
and front wheel brakes engaged by raising and locking the tow bar in an
upright position. The cart is equipped with four 4:80 x 4:00 x 8 tires.
1.1.1.2 | Coolant System
The coolant-dispensing system is used to pump contaminated coolant
from the aircraft. See Figure 1.1.1.2 for coolant system schematic. The fol-
lowing paragraphs describe the major system components:
Coolant Tank
The coolant tank is bolted to the cart frame. The tank is constructed from
type 304 stainless steel. Internal safety baes prevent sloshing and dis-
tribute load forces. The coolant tank has the following features:
COMPONENT DESCRIPTION
Vent
The tank vent is located on top of the tank.
This vent pipe is covered with a mushroom-
type breather/vent cap.
Drain Valve Valve beneath the cart allows the tank to be
drained.
Fill Connection
Fill connection for the coolant tank is 2 inches
in diameter and provided on the top of the
fresh coolant tank.

COMPONENT DESCRIPTION
Level Gauges
The gauges are located on the left side of the
fresh tank and the right side of the waste tank.
They indicate the level of liquid in each of the
tanks.

SECTION 1 | GENERAL INFORMATION & OPERATING PROCEDURES
Flush & Fill Cart SFFC-70/2 | 13
The following coolant system components are located on the Flush and
Fill Cart.
COMPONENT DESCRIPTION
Tank Shuto Valves
This gate valve is located at the tank outlet
into the pump suction line. When closed, this
valve allows service to be performed on the
system without draining the tank. (V6 & V7)
Tank Drain Valves This gate valve is located underneath the tank
to allow coolant to be drained from the tank.
Filter
The lter between the supply hose and the
pump lters impurities from the coolant
leaving the pump. This lter is a 5-micron
absolute lter and has a removable element.
Y Strainer
The strainer prevents particles from entering
the pump. The strainer is located just after
the tank shuto valve.
Pump
The pump delivers coolant from the coolant
tank to the aircraft. This diaphragm pump is
belt-driven by the motor and runs whenever
the motor is running.
Meter
The meter measures, in gallons, the amount
of coolant pumped to the aircraft. The meter
is directly above the main valves. It may
be reset to zero using a knob on the meter
housing.
Sight Glass
The sight glass allows the operator to visually
see that coolant is moving through the service
hoses and into the waste tank.
Check Valves
Two check valves are installed in the system.
They are located before valve 4 to ensure
that coolant does not ow back through the
strainers and into the tanks. Refer to the
coolant schematic (Fig. 1.1.1.2)
1.1.1.3 | Electric Motor
The motor is mounted parallel to the pump in the center of the cart. The
drive shaft of the motor drives through a belt to the diaphragm pump. Op-
erating controls for the motor are located on the control panel.
1.1.1.4 | Electrical System
The electrical system for the cart is a 480 volt three phase AC system.
Electrical Components
The primary electrical components are described below:

Indicators
COMPONENT DESCRIPTION
Electric Motor See motor controls, pre-starting checks and
operating instructions for the motor.
START Button This push button ON/START switch for the
motor is located on the control box.
STOP Button This push button OFF/STOP switch for the
motor is located on the control box.
Heater Control This ON/OFF switch for the heater is located
on the control box.
Shuto Valve, Hose
A ball valve is installed on the aircraft end of
the supply hose. Closing this valve prevents
water in the hose from spilling after the hose
is disconnected from the aircraft.
Meter
The meter is located directly above the main
valves. It measures, in gallons, the amount of
coolant dispensed to the aircraft.
Tank Level Gauge
This oat gauge on the left side of the fresh tank
and the right side of the waste tank indicates the
amount of coolant present in the tank.
Tank Shuto Valve
This gate valve is located at the bottom of
the tank in the pump suction line on both
fresh and waste tanks. It must be open when
pumping coolant and should be closed only
during maintenance.
1.2.2 Pre-Operation Checks
The following checks should be performed at the beginning of each day
or shift:
1. Make sure brakes operate properly.
2. Check hoses for cracks and wear.
3. Check the tank level gauge to make sure there is ample coolant in
the tank. Make sure the tank vent is not plugged before lling tank.
4 . Check condition of the tires and wheels.
1.2 | OPERATION
NOTE:
The pump operates whenever
the motor is running.
