At the end of the operation, in the event of a very quickly fl ashing LED
light (0.1s ON 0.1s OFF) and an intermittent buzzer coordinated with
the LED light, this is to inform the operator that the maximum pres-
sure has not been reached. The display will show the following fl ashing screen
"ERROR"
(Ref. to
section 6.6
for further details).
STEP 2 – Bringing the cutting head down into the manhole
Secure the pump in proximity of the manhole or to the ladder, using the shoulder strap supplied
(Ref. to Fig. 6).
The maximum distance between the cutting head and the pump is 33 ft (10
m) assuming that the pump is positioned in proximity of the manhole or on the ladder under
the street level.
Do not place the pump on dirty surfaces or in the presence of water
.
Lower the cutting head and the fl exible hose into the manhole.
Position the blades of the cutting head perpendicularly around the cable that has been identi-
fi ed for the cut, as described in the operation manual of the cutting head.
Stabilize the cutting head position and support the head by strapping it to the above wires or
cable holders. It is possible to hook the cutting head with the
SS-TCY strap
hooked to the hang-
ing points of the head.
Connect one end of the grounding wire to the cutting head and the other end to the relevant
grounding attachment (Ref. to operation manual of the cutting head).
Connect the flexible hose to the cutting head (Ref. to Fig. 5),
the operator should now leave the manhole
.
After all personnel have exited the manhole or cable space,
connect the flexible hose to the pump (Ref. to Fig. 5).
Insert the battery.
Wake up the pump by pressing forward the control button (11)
(display
ON).
STEP 3 – Cutting operation
A protected zone must be established around the work place where entry is forbidden.
Switch on the radio control by pressing the start ON/OFF button (1), the LED will fl ash green.
In proximity of the manhole, at a safe distance, push the pump button (2) on the radio control
to start the cutting operation (Ref. to Fig. 4).
The maximum distance between radio control
and pump is 66 ft (20 m) if within line of sight.
During the cutting operation the pump's LED light will fl ash intermittently and the
buzzer emits an audible signal coordinated with the LED light (0.4s ON 0.4s OFF).
In the event that the buzzer is not heard, hold the pump button (2) for 1 minute, after
1 minute the pump button can be released to start the automatic release of the cutting blades.
