OPERATION UNDER USUAL CONDITIONS - CONTINUED

PRESSURE DISCHARGE (LOWER SPRAY BAR) - CONTINUED
NOTE
When using lower spray bar for de-icing operations, extension attachments may be mounted at each end
of lower spray bar to increase width of coverage to 16 feet (4.9 m) (WP 0006 00).
1.
Place pump control switch to ON (pressure) position.
2.
Turn PRESSURE GRAVITY control to ON.
3.
Move pump control lever (elevator control lever) to PUMP ON, SLOW.
NOTE
Making several passes to discharge liquid is preferable to making one pass, where application is so heavy
4.
Begin pressure discharge operation.
a.
Set engine, transmission, and pump at appropriate speeds for desired application rate. Make successive passes and
ensure an appropriate overlap of coverage.
b.
Monitor results and adjust coverage volume as needed: too heavy an application will result in flooding or forma-
tion of puddles, and will be a waste of material; too light an application will not achieve desired results.
CAUTION
Tank may be raised slightly to allow discharge of residual fluid that has pooled at bottom of tank. However,
do NOT continue to discharge after EMPTY indicator light on control panel has come on. Damage to pump
could result.
5.
When pressure discharge is complete, turn off pump with pump control lever (elevator control lever) and reduce engine
RPM.
6.
Turn PRESSURE GRAVITY control to OFF.
7.
Place pump control switch to OFF (suction) position.
8.
Refill tank and repeat operation as required.
CAUTION
Do NOT leave machine after operation without flushing/rinsing tank, if tank amendments were used during
mission. Tank must be clean and dry to ensure effectiveness of subsequent operations. Improper cleaning
will result in accumulation and build-up of amendments in tank. Premature failure or damage to plumbing or
pump may result. Effectiveness of amendments used may also be reduced
9.
When pressure discharge is complete, flush/rinse tank to remove all traces of amendment.
