Water Spray System

wc_tx000865gb.fm
Water from the tank is fed to the spray bars by an electric pump. The
flow of the water is controlled by a switch and a rotary dial.
Press the upper half of the water spray switch (61) to turn the water
pump on. Turn the water spray dial (62) clockwise to increase the
spray frequency. Turn the water spray dial counter-clockwise to
decrease the spray frequency. Press the lower half of the water spray
switch (61) to turn the water pump off.
Only use clean water. Dirty water, even when filtered, will rapidly clog
the tubes of the spraying equipment.
During winter, or when temperatures drop to below 0°C (32°F), drain
the water tank and spraying equipment. Run the water pump to
remove excess water from the system. Drain the water through the
water drain plug (41) located near the bottom of the rear frame,
through the sprayer end plugs, and the water filter. Freezing water may
cause broken hoses, filters and water pumps and may deform the
water tank.
