4.3.4.2 Adjusting Cleaner Nozzle Direction
The PATTERN of cleaner spray is determined by the setting of the spray nozzles. The
spray nozzles emit a fan-shaped pattern (the center nozzle has a wide spray pattern while
the outside nozzles have narrow spray patterns) that can be adjusted as shown in Figure 4-
17. First, all three nozzles can be rotated to spray cleaner in either a more horizontal or
more vertical orientation depending on the position of the nozzles. Secondly, the angle of
the two outside nozzles can be adjusted to aim the spray more towards the middle of the
lane or more towards the outside of the lane, as needed. Third, the center nozzle can be
adjusted so that the nozzle points further up or down. Together, the spray pattern can be
fine-tuned to meet your needs.
Figure 4- 17
The top view of Figure 4- 17 shows that the two outside nozzles can be angled to spray
more towards the middle or outside of the lane. The side view shows that the center nozzle
can be angled with respect to the lane surface. The front view shows that the nozzles can
be rotated with respect to the lane surface. Perform the following procedure to adjust the
direction of the spray nozzle with the machine in the
operating
position.
