3.7.1 CARBIDE SPIKES
The BlitzForce 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).
3.8 FULL TIME SWIVEL INLET HOSE COUPLING
The BlitzForce Portable Monitor has a full-time swiveling inlet coupling so that when the hose is charged, any twist in the hose will
minimize the lifting of the spikes off the ground. The monitor is equipped with three spikes to provide traction when flowing from the
ground. For the spikes to provide traction they must remain in contact with the ground. Assure that the hose is not on top of anything that
would cause the spikes to be lifted off the ground.
3.9 OUTLET PIVOTS AND SAFETY ELEVATION PLUNGER
The monitor’s outlet pivots to allow for 20 degrees of horizontal rotation either side of center. The elevation range is from 20 to 60
degrees manned and 30 to 60 degrees unmanned (30 to 50 degrees with the oscillator version). While manned, to lower the outlet below
the 30 degrees elevation, push down the outlet to the desired elevation. Below the outlet pivot is a spring-loaded plunger that returns the
outlet to 30 degrees if the operator releases on the outlet or the monitor is unmanned. The pivots are easy to reposition under pressure
and are good for rapid redirecting of the stream.

3.10 ELEVATION HOLDING MECHANISM
The elevation pivot has a mechanism to support the weight of a nozzle. It is factory set to support the weight of nozzles likely to be used.
It may be adjusted. The mechanism releases when raising the nozzle so upwards drag from the mechanism is not felt. Avoid the use of
long stream straighteners or heavy nozzles which may overcome the holding torque of the elevation mechanism.
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.
