Ryobi P661 Operation Manual - Page 6

OPERATION  Push the large end of one pin until the opposite end is fully extended on the other side of the jaw. Slide the notch of the insert over the extended side of the pin as shown. NOTE: Make sure to place the flat side of the insert on the outer side of the tool jaws.  Repeat with the second insert.  Close the tool jaws and check to make sure the inserts are securely installed. To remove inserts:  Remove the battery pack.  Open the jaws and push each pin outward to remove the inserts. SWITCH TRIGGER/LED WORKLIGHTS See Figure 5, page 8.  Tapping or pulling the switch trigger activates the LED worklights on each side of the tool jaws to illuminate the work area.  When the tool is not in use, the time-out feature will cause the lights to start fading and then shut off. The LED worklights illuminate only when there is a charged battery pack in the tool. INSTALLING A CRIMP RING See Figures 7 - 9, page 9.  Install the battery pack.  Slide a PEX crimp ring onto a section of PEX tubing, about 2 in. past the cut end of the tubing.  Install inserts as described earlier in the manual if the PEX tubing is smaller than 1 inch.  Insert a PEX fitting into the tubing until the shoulder of the fitting touches the end of the tubing.  Push the PEX crimp ring toward the fitting until it is 1/4 in - 1/8 in. from the end of the tubing.  Open the tool jaws. Position the jaws directly over the crimp ring at a 90° angle. NOTE: Make sure the jaws fit completely and squarely over the crimp ring before pulling the switch trigger.  To begin a cycle, press and hold the switch trigger for one-half to one second.  The green LED indicator will come on when the cycle is 50% complete.  It is not necessary to continue holding the switch trigger during a cycle. The tool will continue to function as long as the trigger is not pressed a second time before the cycle is completed.  When the cycle has been successfully completed, the LED indicator on the base of the tool will be green.  If the red LED indicator comes on, this indicates an incomplete cycle. Repeat the instructions for beginning and completing a crimping cycle. The LED indicator on the base of the tool will be green when the cycle is successfully completed.  Remove the tool from the PEX crimp ring. GO/NO GO GAUGE See Figure 10, page 9. Before each use, run a test cycle with the tool. Use the GO/ NO GO gauge to check for a satisfactory result.  Install the desired size of inserts (if needed) and a crimp ring onto a section of PEX tubing.  Complete a crimping cycle as described in Installing A Crimp Ring.  After a test crimping cycle, insert the crimped ring into the corresponding slot on the gauge.  If the crimped ring fits into the "NO GO" side, the tool must be serviced before further use. NOTE: This tool has no user serviceable or replaceable parts.  If the crimped ring fits into the "GO" side, the tool is ready for use. MAINTENANCE NOTE: This tool has no user serviceable or replaceable parts. GENERAL MAINTENANCE Avoid using solvents when cleaning plastic parts. Most plastics are susceptible to damage from various types of commercial solvents and can be damaged by their use. Use clean cloths to remove dirt, dust, oil, grease, etc. NOTE: ILLUSTRATIONS START ON PAGE 8 AFTER FRENCH AND SPANISH LANGUAGE SECTIONS. 6 - English
