How to use the RAC IV tip guard.

WARNING

INJECTION HAZARD

To reduce the risk of serious injury, whenever you are instructed to relieve pressure, follow the Pressure Relief

Procedure on page 9.

The tip guard alerts you to the risk and helps prevent placing any part of the body close to the spray tip. The tip guard also adjusts the vertical or horizontal spray pattern. See Fig. 9. The tip guard holds a reversing spray tip. The tip is in the spraying position when the tip handle points forward. See Fig. 7.

Clean the front of the tip frequently during the day's operation. First, follow the Pressure Relief Procedure on page 9.
