The portable base legs are extended by following these steps:
(Refer to figures 4.2.1, 4.2.2, & 4.2.3)
a) Hold the base carrying handle with one hand and grasp the end of one of the longer
legs with the other hand. Pull this leg away from the base forward in an arc, until the
locking pin engages. The locking pin is spring loaded and automatically engages when
the legs are in the correct position. Watch the leg lock knob drop down, even with the
lower band on the base, indicated by an arrow.
b) Repeat procedure (a) to extend other set of legs.
c) Set portable base on even ground with all leg spikes in contact with the ground.
4.0 SAFE-TAK 1250 BASE
The portable base allows the monitor to be positioned in places that are not accessible with a fire truck. As an added measure of safety,
the SAFE-TAK 1250 portable base has a safety valve. The function of the safety valve is to quickly reduce flow should the monitor, and
portable base, ever leave the ground for any reason. After the water supply is shut down and the cause of the instability corrected the
valve may be reset and water flow resumed. The legs are made of spring steel and will flex when in use to compensate for small ground
irregularities. Do not reset the safety valve without first shutting off the water flow.
4.1 SITE SELECTION
Safe operation of the monitor on the portable base begins with site selection. The site should be a safe distance from the fire yet within
reach of the nozzle stream. Select a flat even surface within 8 feet of a sturdy stationary object that can be used as an attachment point
for the anchor strap. Set up the portable base with the anchor point between the portable base and desired target of the nozzle stream.
On ground, such as sand, mud, or gravel, wash out under the paddle may cause unwanted tripping of the safety valve on the SAFT-TAK
1250® portable base. In such case, a thin flat object, such as a clipboard, may be placed under the paddle.
Object under paddle
must not keep any leg spike from contacting ground.

Keep the anchor strap near the monitor as it will be used to anchor monitor before use.
4.3 PORTABLE BASE LEG SPIKES
The SAFE-TAK Base has 5 or 6 tungsten carbide tipped spikes on the legs and base to
resist sliding by digging into the surface the base is sitting on. The amount of sideways
force these spikes can withstand depends upon several factors, particularly, 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. This is why the portable base must be well anchored. These
spikes are essential to safe operation of the monitor base and must be in contact with
the ground at all times. Do not operate without first securing the monitor with safety lines
to prevent sliding. Set the monitor on an even surface so that all the spikes contact the
ground. See section 5.0 for spike inspection procedures.
