5.7 HOSE CONNECTION

Make the hose connection(s) to the portable base and extend the hose(s) straight back from the portable base at least 10 feet (3
meters). If only one inlet of a double inlet base be used, a clapper valve will automatically close off the other inlet. Use caution when
turning on the water to the monitor on the portable base. As the hose fills it will become stiff and may cause the monitor and portable
base to slide or tip or both. Open the pumper valve to the monitor slowly.

5.8 PORTABLE BASE STORAGE

The portable base may be stored in a compartment, on the optional storage
bracket, TFT part number XF-B. This bracket is NOT designed to withstand the
reaction forces of an operating monitor stream. It is to be used for storage and
transportation only. The storage bracket may be mounted on a horizontal surface,
horizontally or vertically on a vertical surface, or on the underside of a horizontal
surface such as the top of a compartment. A strap helps hold the base on the
bracket. Mounting instructions are supplied with the bracket.

5.9 PRESSURE RELIEF OPTION

The optional pressure relief valve on the single inlet portable base can be adjusted
to open between 50 and 200 psi. The pressure relief valve, TFT part A1820, is set at
the factory to open at 150 psi. To change the relief pressure refer to the label on the
bottom side of the pressure relief valve. A pressure relief valve can be added to the
single inlet portable base by removing the cover on the side of the base. For
additional information call 800-348-2686.

5.10 PRESSURE RELIEF VALVE SETTING

To set the relief valve pressure turn the adjusting screw on the relief valve housing
until the surface of the screw is even with the desired pressure. Do not cap or plug
discharge opening.

6.0 MAINTENANCE

The CROSSFIRE® monitor and its base require little maintenance. The unit should be kept clean and free of dirt by flushing with water
after each use. All controls should be checked for freedom of movement and condition. Any inoperable or damaged part should be
repaired or replaced immediately. Specific areas to check are as follows:
Truck Mount Base:
1) Sealing surface above swivel joint must be smooth.
2) Swivel joint must rotate freely.
