HSS Hire 49510 Troubleshooting guide

This method should never be used to apply a
signal to ELECTRIC CABLES.
Plug the black plug into the socket in the base of
the Signal Generator. Connect the crocodile clip
(red lead) onto the appropriate service. Place the
earth stake into the ground, at right angles to, and
as far from the service as possible, connect the
black lead onto the earth stake.
Make sure you do not drive the earth stake into
any services below it.
Switch the Signal Generator ON/OFF Mode
selector to the mid position. The unit will emit a
high beep every 2 seconds (this confirms the
batteries are ok) If the beep stops, STOP and
replace the batteries.
After a short time the beep will change to a lower
tone indicating a good earth connection.
The area to be excavated should always be tested
in both power and radio mode.
Mark out the area to be excavated using line
marker or chalk. Never mark services using pegs or
other sharp objects.
Always sweep the area in two directions – north to
south and east to west.
Holding the C.A.T. upright with the blade edge off
the ground, sweep the area in a grid like pattern
taking care not to ‘swing’ the unit. Cover the area
until either a signal is located or until you are fully
satisfied that the area has been adequately tested
first in power mode then in trace mode.
To discover the direction of the service you have
located, rotate the C.A.T. when directly over the
service. The direction will be shown when the
meter display drops to zero and no sound is
emitted.
Mark any services found clearly.
TO OPERATE THE C.A.T. IN CONJUNCTION WITH A
SIGNAL GENERATOR…
Switch on the Generator, check that a high pitched
tone is being emitted every 2 seconds
The C.A.T. will pick up stray signals from the
Generator for approximately 5 metres, beyond 5
metres the C.A.T. will act normally allowing you to
locate audibly as well as visually.
With the C.A.T. switched ON ‘sweep’ over the area
to be excavated, listening for the high pitched
tone and checking the meter on the C.A.T. When
the meter peaks, this indicates the service is
directly below the arrows on the C.A.T. unit.
BASIC TECHNIQUES
The C.A.T. and Generator are each powered by
4xLR14 batteries.
Never push the equipment beyond its design
limits. If it will not do what you want with reasonable
ease, assume you have the wrong tool for the job. Ask at
your local HSS Hire Shop for advice.
Handle the equipment with care. Avoid dropping it,
knocking it, or otherwise exposing it to damage.
Never expose the equipment to excessive
moisture, dust or dangerous/corrosive chemicals.
Keep the equipment clean. You will find this less of a
chore if you clean up regularly rather than wait until the
end of the hire period.
When not in use, store the equipment somewhere
clean, dry and safe from thieves.
Clean the equipment by wiping it over with a
damp cloth, before returning it to your local HSS
Hire Shop.

CABLE AVOIDING TOOL (C.A.T.)…
The C.A.T. has three modes, each for detecting
services in a different way.
POWER MODE ‘P’:
Detects live electric cables which have a current
flowing through them. Some electric cables may be
live but there may not be a current flowing through
them. To ensure there is a current flowing, ask for an
appliance to be switched on, such as an electric cooker
or an immersion heater.
RADIO MODE ‘R’:
Detects re-radiated signals from metallic objects
such as pipes and cables. The re-radiated signal range
is approximately 16-20khz. In this mode the C.A.T. will
only detect electric cables and metallic pipes not plastic.
SIGNAL GENERATOR MODE ‘S’:
Detects signals produced by the signal generator.
TO USE THE C.A.T. …
IN POWER MODE:
Select the ‘P’ mode and rotate the sensitivity
control to maximum (clockwise). Lift the C.A.T. by
the handle and apply pressure to the switch. You
GETTING STARTED
Caution
The C.A.T. and Signal Generator will identify most
underground services BUT the absence of a positive
indication does not guarantee the non existence of a
pipe, cable or service.
ALWAYS EXCAVATE WITH CARE.
GENERAL SAFETY will hear a single beep test signal confirming that
the batteries are servicable. The unit is ready to
detect buried power cables.
IN RADIO MODE:
Select the ‘R’ mode and rotate the sensitivity control
to maximum (clockwise). Lift the C.A.T. by the
handle and apply pressure to the switch. You will
hear a single beep test signal confirming that the
batteries are serviceable. The unit is ready to detect
buried metal objects re-radiating a radio signal.
POWER, RADIO & SIGNAL GENERATOR MODE:
On locating a signal, reduce the sensitivity of the
signal if the meter is reading more than 2. The
metre reading rises then falls as you pass over a
service. Continue to sweep until the highest signal
(maximum response) has been obtained.
Having found the maximum response, turn the
sensitivity control down so that the meter is
reading just above 1/4 scale and the audio beep
can just be heard
Now rotate the C.A.T. about its vertical axis, when
the signal is at its greatest, the C.A.T. is positioned
at 90degrees to the path of the buried service.
HEADPHONE SOCKET:
Plugging a set of headphones into the socket will
automatically mute the speaker and enables the
operator to work in noisy environments.
SIGNAL GENERATOR…
The Signal Generator can be used to apply a
distinct signal by induction or connection. To
locate metal services which either do not carry live
electric current or do not re-radiate radio signals.
The Signal Generator is supplied with an earth
stake and crocodile clip ended connection lead set.
To access these, turn the fastener anti-clockwise
and remove the accessory hatch cover under
the unit.
The signal generator is used to apply a direct
signal to a specific service, however, the signal
may re-radiate to nearby services.
INDUCTION MODE:
Place the Generator over the service and at right
angles to it.
When the signal generator is switched to the
induces mode it emit an audible high pitched tone.
A signal will be sent down the chosen service to be
picked up by the C.A.T.
CONNECTION MODE:
Allows you to put a direct signal on to a buried
service when in connection mode.
You may apply a signal to a service in this mode by
connecting the crocodile clip connectors.
