Various nozzles may be quick connected into the end of the adjustable pressure
dual lance to change the spray pattern or use the detergent feature. When
using Quick- connects (Q.C.), be certain the connection is securely locked.
(See illustration #7). If not, the high pressure water may shoot the nozzle
from the lance, causing severe injury or serious damage. To determine spray
fan, (see illustration #8) refer to the actual number stamped on the nozzle.
The first two digits indicate the spray fan in degrees, i.e., 00=0°, 15=15°,
25=25°, 40=40°.
