4.2.3 SLOW CLOSE FEATURE
The BLITZFIRE has a valve damping mechanism to slow valve closure as it approaches OFF, to reduce the effects of water hammer.
The damping mechanism has a vane moving in dampening fluid connected to the valve handle on the left side of the monitor.
4.3 FOLDING LEGS
The BLITZFIRE Portable Monitor has two legs that fold for storage and unfold for operation. The legs are held in the folded and unfolded
position by spring detents. To fold or unfold the legs:
1. Grasp the spike end of one leg and pivot it to the folded or unfolded position.
2. Repeat for the other leg.
4.3.1 CARBIDE SPIKES
The BLITZFIRE Portable Monitor has 3 tungsten carbide tipped spikes on the legs and the base to resist sliding by digging into the
surface the monitor is sitting on. The amount of sliding force these spikes can withstand depends upon the amount of downward and
sideways force that is on the base, and the hardness and texture of the surface the spikes are in contact with. At low elevation angles, it
is difficult for these spikes to resist sliding. These spikes are essential to safe operation of the monitor and must be in contact with the
ground at all times. Set the monitor on an even surface so that all three spikes contact the ground. Replace any spike if the tip diameter
exceeds 1/16 inch (1.6mm). Contact TFT to order Replacement Spike Kit XX482-KIT.
WARNING
Improper servicing of the slow close device may result in a malfunctioning Safety Shut-Off Valve,
which could cause injury or death. If service is needed on the slow close device, contact Task Force
Tips. Do not add or change dampening fluid.
WARNING
Water Hammer occurs any time a valve is closed when water is flowing. This can cause sudden
movement or ruptured hose lines, which could result in injury or death. The dampening device in
the Blitzfire monitor reduces the effects of water hammer, but DOES NOT ELIMINATE IT! All
personnel should adhere to procedures approved by the AHJ to avoid risk when near any hose that
might be shut off quickly.
WARNING
In the unfolded position, the legs provide a stable base for operation of the monitor. Lack of stability
can cause an out of control monitor resulting in injury or death. Do not operate as a portable
monitor with one or both legs in the folded position.
WARNING
For stable operation all spikes must maintain contact with the ground. Lack of stability can cause
an out of control monitor resulting in injury or death. Do not place the monitor on top of debris,
objects, or uneven terrain that could keep any of the spikes from contacting the ground.
WARNING
On hard slippery surfaces the spikes may provide little resistance to sliding. A sliding monitor may
become out of control and may cause injury or death.
To help increase resistance to sliding:
• Tie off the monitor
• Hook the legs on a stationary object
• Apply a person’s weight to the monitor
• Replace any spike if the tip diameter exceeds 1/16 inch (1.6 mm)
CAUTION
Spikes are sharp and exposed. Use care around spikes to avoid injury and damage to clothing or
other property.
