6.5.1 STREAM STRAIGHTENERS WITH STACKED TIP NOZZLES
Turbulence though the Tornado Monitor is very low, but stream quality and reach can be improved with the use of a stream straightener
on the TFT stacked tip nozzle. See figure 6.4.2 for the TFT stream straightener friction loss.
6.5 STREAM STRAIGHTENERS
6.5.2 STREAM STRAIGHTENERS WITH FOG NOZZLES
When using a fog nozzle for flows below 300 gpm (1,100 l/min), it is recommended that no stream straightener be used since the fog
nozzle's flow path generally serves as a stream straightener. Above 300 gpm (1,100 l/min), TFT's 5 inch Stream Straightener will
generally improve a fog nozzle's stream.
7.0 MAINTENANCE AND INSPECTION
The Tornado Monitor requires little maintenance. The monitor should be kept clean and free of dirt. All controls should be checked for
freedom of movement and proper operation periodically. Any inoperable or damaged parts should be repaired or replaced immediately.
Make sure that the monitor rotates freely and without binding throughout its range of travel.
Make sure that there are no leaks when the monitor is flowing water.
Make sure the nozzle is free of debris.

7.1 LUBRICATION
The Tornado monitor generally should not require greasing. In the event that the operation becomes stiff, grease may be applied to the
horizontal rotation and elevation worm gears. See figure 3.2B for grease port locations. Use medium viscosity automotive chassis
grease. Apply only enough grease to restore normal operation. If normal operation is not restored by greasing, inspect for other causes
of stiff operation.
Note: Do not over pump grease. The grease fittings are located close to the seals and only an ounce or so of grease should be sufficient.
7.2 PERFORMANCE TESTING
Performance tests should be conducted on the Tornado Monitor after repairs are made, or any time a problem is reported to verify
operation in accordance with Task Force Tips test procedures. Consult the factory for the procedure that corresponds to the model and
serial number of your monitor. Any equipment that fails the test criteria should be removed from service immediately. Equipment can be
returned to the factory for service and testing.
