5.1.4.2 TRIGGER FLOW CONTROL SPEED ADJUSTMENT

The IMPULSE valve contains a slow close mechanism to prevent the nozzle from
slamming  oﬀ   if  the  trigger  is  suddenly  released.  The  closing  speed  is  set  at  the
factory  to  be  slow  enough  to  reduce  water  hammer,  (“water  hammer”  is  always
present in any valve when it is shut oﬀ . The slow close mechanism will reduce this
but cannot eliminate it completely) but fast enough to reduce the  potential danger of
hose whipping from a dropped nozzle. The closing speed may be adjusted as shown
in the ﬁ gure.5.1.4

Slower

Close

Close

NOTICE

The High Pressure 1 inch (25 mm) models do not
have the slow close feature. They are often used in
pulsing applications and need to close quickly.

Do not unscrew the adjuster past the end of the hand grip (to unscrew it too far
could result in the loss of dampening ﬂ uid).

Figure 5.1.4

WARNING

As the closing time is increased so does the risk of injury from an out of control nozzle. A ﬂ owing
nozzle can cause injury within the ﬁ rst second of lost control. Use caution when adjusting the
closing speed and always verify performance after adjustment.

WARNING

The Slow Close Feature relies on a ﬂ uid and air combination in the pistol grip. For proper function,
the  pistol  grip  should  be  within  its  normal  operating  position.  The  normal  operating  position
is  with  the  nozzle  horizontal  or  pointing  up  with  the  pistol  grip  within  45  degrees  of  vertical.
Releasing the trigger suddenly outside of the normal orientation will likely result in faster shut-oﬀ
causing a higher pressure spike and increasing the risk of a burst hose.  Do not suddenly release
the trigger when operating outside of the nozzle’s normal orientation.

5.1.4.1 IMPULSE TRIGGER LOCK

Use an 1/8” (3mm) punch to push out pin
and remove lock if the lock is not desired.

To Lock:

Push on the lock while pulling back the

trigger to engage one of the four locked positions.

To Un-Lock:

Pull back slightly on trigger without any

pressure on the lock. The spring loaded lock should
automatically move to the unlocked position.

WARNING

When the trigger lock is engaged, the nozzle will not shut oﬀ if dropped. Always shut oﬀ nozzle
before releasing the pistol grip to avoid injury from an out of control nozzle.
