It has been manufactured exchanged on new nozzles. Please specify desired threads when with great care to give you the finest performance possible. All ordering. components are of be made by selecting the desired coupling or base. Couplings with top quality and extremely rugged. With occasional inspection and attention it will serve you for many years. This publication is intended for those who prefer to perform service on their own equipment. Factory service is available and encouraged and in most cases seldom exceeds 24 hours in our facility. Factory serviced equipment is serviced by experienced technicians, and fully tested before being returned. Repair charges for non-warranty items are usually minimal, and all equipment is promptly returned after servicing.

(Nozzle Repair Kits and Service Fixtures) LIH-020 February 15, 1999 Rev 1 FIELD LUBRICATION PROCEDURE — USE THIS PROCEDURE ONLY IF THE NOZZLE CONTROLS BEGIN TO TIGHTEN All Task Force Tips nozzles are factory lubricated with high quality silicone grease. This lubricant has excellent washout resistance and long term performance in fire fighting nozzles. If your department has unusually hard or sandy water, the moving parts of the nozzle may be affected. Foam agents and water additives contain soaps and chemicals that may break down the factory lubrication. The moving parts of the nozzle should be checked on a regular basis for smooth and free operation, and for signs of damage. IF THE NOZZLE IS OPERATING CORRECTLY, THEN NO ADDITIONAL LUBRICATION IS NEEDED. Any nozzle that is not operating correctly should be immediately removed from service. Field use of Break Free CLP (spray or liquid) lubricant will help to restore the smooth and free operation of the nozzle. However, these lubricants do not have the washout resistance and long term performance of the silicone grease. Therefore, continued re-application of Break Free CLP will be needed on a regular basis. CAUTION: Aerosol lubricants contain solvents that can swell O-rings if applied in excess. The swelling can inhibit smooth operation of the moving parts. When used in moderation as directed, the solvents quickly evaporate without adversely swelling the O-rings. The nozzle can be returned to the factory for a complete checkup and relubrication with silicone grease. PART ONE COUPLING DOWN Position the nozzle at a 45 degree angle with the COUPLING end down. CLOSE the valve handle and set the pattern to STRAIGHT STREAM. Then spray a 5 second burst in these areas: #1 #2 #3 . FRONT PATTERN CONTROL SEAL Spray between the pattern control and the barrel cone. PRESSURE CONTROL UNIT Spray down the center of the end screw. FRONT SLIDER SEAL a)Rotate shaper into FLUSH position. b)Spray down the front end of the nozzle to dribble lubricant into the clearances between the slider and the valve body. While holding nozzle at the angle, wait 30 seconds for the lubricant to penetrate into the clearances. Cycle the valve handle and rotate the shaper from straight stream to full flush several times, and then proceed to the next section. PART TWO COUPLING UP Position the nozzle at a 45 degree angle with the BUMPER end down. OPEN the valve handle and set the pattern to FLUSH. Then spray a 5 second burst in these areas: #4 #5 #6 REAR SHAPER SEAL Spray down the clearance between the label and the shaper guide. REAR SLIDER SEAL Spray into the clearance between the slider and the valve body. FLUSH MECHANISM SEAL a) With the handle on the top, spray down into the nozzle. The aerosol extension tip will help direct the spray into the clearance leading to the O-ring. b) Rotate nozzle so the valve handle is on the bottom and spray another 5 second burst. #7 DETENTS IN THE HANDLE Spray a small amount on the detent followers located in the handle. While holding nozzle at the angle, wait 30 seconds, then cycle the valve handle several times. Rotate the pattern control from straight stream to full flush several times. The pattern control should move freely and easily. The barrel cone should move forward to within 1/16" of the baffle before the shaper reaches straight stream position. Wipe off excess lubricant. IF THIS PROCEDURE DOES NOT RESTORE SMOOTH AND FREE OPERATION OF ALL THE MOVING PARTS, THEN FACTORY SERVICE IS NEEDED. Call the 24-HOUR HOT LINE 800-348-2686.
