Retracting Portable Base Legs - Task Force Tips SAFE-TAK 1250 Operation And Maintenance Instructions

5.3 RETRACTING PORTABLE BASE LEGS

For carrying and storage, the legs are retracted as follows:
a) Pull up on one of the spring loaded leg lock knobs, grasp the forward leg, on the same side, and push it, in an arc, towards
the rear of the unit. The leg lock knob may be released as soon as the front leg begins to move out of position. Continue to
push until both legs come in contact with the rear stop.
b) Repeat procedure (a) to retract the other legs.
5.3 PORTABLE BASE LEG SPIKES
The Safe-Tak 1250 Portable Monitor has (5 or 6) 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 diffi cult 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 spikes contact the ground. Replace any spike
if the tip diameter exceeds 1/16 inch (1.6 mm).
Spikes must be sharp to provide resistance to sliding. Replace any spike if the tip diameter
CAUTION
exceeds 1/16 inch (1.6 mm).
Spikes are sharp and exposed. Use care around spikes to avoid injury and damage to clothing or

other property.
5.5 PORTABLE BASE ANCHORING
The safest method of restraining the monitor is to use a tie down strap. It is inherently more reliable than other methods since it
does not rely on traction or digging in of the spikes. It is also the safest method because even if the monitor slides its travel is limited
by the strap length. A forward attachment point and a strap are provided with the Crossfi re. A loop on the end of the strap may be
placed over the anchor point or the strap may be wrapped around an object, such as a tree, and the snap end of the strap passed
through the loop and pulled tight. Keep the entire length of the strap as close to the ground as possible. Snap the hook into the hole
in the front of the Crossfi re. If the strap is too short to reach a suitable anchor, it may be extended with strong rope or chain. Keep
the distance between the monitor and anchor as short as possible. Remove all slack between the monitor and anchor before fl owing
water.
WARNING
At low nozzle elevation angles the base may also require additional anchoring. The ability of a single anchor to stop sliding is a
function of the horizontal angle between the strap and water stream. When the stream is in line with the anchor any sliding will be
arrested by the anchor. As the horizontal angle increases between the anchor strap and the stream, the base can begin to slide in
an arc around the anchor point. In this situation multiple anchor points may be required.
The strap should be stored inside the monitor base when not in use. The black rubber cap on the strap will hold the strap in the base
and protect the sealing surface of the quick connect swivel joint.
