9.0 MAINTENANCE

TFT  products  are  designed  and  manufactured  to  be  damage  resistant  and  require  minimal  maintenance.  However,  as  the  primary

firefighting tool upon which your life depends, it should be treated accordingly. To help prevent mechanical damage, do not drop or throw

equipment. 

9.1 FIELD LUBRICATION

All Task Force Tips nozzles are factory lubricated with high quality silicone grease. This lubricant has excellent wash out resistance,

providing long term performance in firefighting nozzles. If your agency 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 LUBRICANT IS NEEDED. Any nozzle that is not operating correctly

should be immediately removed from service. The nozzle can be returned to the factory at any time for a complete checkup and re-

lubrication with silicone grease.
The field use of Break Free CLP (spray or liquid) lubricant will help to temporarily restore the smooth and free operation of the nozzle.

These  lubricants  do  not  have  the  washout  resistance  and  long-term  performance  of  the  silicone  grease.  Once  Break  Free  CLP  is

applied, re-application will be needed on a regular basis until the nozzle can be returned to the factory for a complete checkup and re-

lubrication with silicone grease. 

9.2 FIELD LUBRICATION (SLIDE VALVE AND PATTERN CONTROLS)

PART 1 - 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 short

burst into these areas:

#1  FRONT PATTERN CONTROL SEAL

      Spray between the pattern control and the barrel.

#2  FRONT SLIDER SEAL

7. Rotate the shaper into FLUSH position.

8. Spray down the front end of the nozzle to dribble lubricant into the clearances

between the shaper and the valve body.

While holding the nozzle at an 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 2 - 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 short burst into these areas:

#3  REAR SHAPER SEAL

      Spray down the clearance between the label and the shaper guide.

#4  REAR SLIDER SEAL

      Spray down the clearance between the slider and the valve body.

#5  FLUSH MECHANISM SEAL

1. With the handle on top, spray down into the nozzle. The aerosol extension tip

will help direct the sprat into clearances leading to the O-ring.

2. Rotate the nozzle so the valve is on the bottom and spray another short burst.

While holding the nozzle at an angle, wait 30 seconds for the lubricant to penetrate into the clearances. 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 OPERATION OF THE IMPULSE TRIGGER SYSTEM,

THEN FACTORY SERVICE IS NEEDED. • 24-HOUR HOT LINE — 800-348-2686 • tft.com

 

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.
