6.3 ANCHORING BY SPIKE HOLDS
The holding ability of the spikes is generally excellent on surfaces like asphalt, wooden and carpeted floors because they allow the spike
to penetrate well. On hard smooth surfaces such as ceramic tile, smooth concrete, marble, terrazzo, or steel decking the BlitzForce
Portable Monitor’s spikes may not hold well. Placing the spikes into cracks, expansion joints, gratings or the like will help hold the
monitor from sliding. Even with the spikes anchored, sliding may be caused by the surface cracking under the load, or from the hose or
nozzle moving the monitor thereby dislodging the spikes from their hold.
The holding ability of the spikes on soft surfaces such as sand, gravel and mud is generally poor. Other anchoring methods should be
considered.

6.4 ANCHORING BY HOOKING LEGS
The legs on the BlitzForce Portable Monitor point back slightly so they can act as a hook for anchoring on posts, walls, door frames or
other fixed objects. Sliding can occur if the legs are unhooked due to the influence of the hose, nozzle, or operator.
