THE AUTO CABLE DRUM
The Auto-Drum Control Handle
The Control Handle is operated by pulling outwards (towards
the operator) and then moved upwards or downwards to select
operation. The handle can then be released when the
operation has been selected. This is best performed with the
left hand with the thumb braced against the legend plate, the
handle is designed with a strong spring so that the handle
cannot be inadvertently moved.
WARNING: The Drum can provide a lot of power and care should
be taken that the crawler cable is not snagged as this may dam-
age the cable. The Drum can realise a pull of around 12Kg so also
ensure that the drum cannot be pulled towards a culvert.

THE AUTO CABLE DRUM
AUTO
This is the setting used for normal operation. The cable can be pulled from
the drum by hand or by the crawler. The drum is designed to provide a small
amount of tension in the cable so that if it is released the cable will return to the
drum. Auto works with or without the crawler so that cable can be pulled from the
drum without the crawler connected, the cable can then be connected to the
crawler when in place and the survey can start. There are no voltages or power in
the cable and it is safe to handle.
The cable drum will release cable when the crawler is moving forwards always
keeping a small amount of tension. It is the crawler that pulls the cable, the drum
uses its motor to keep in synchronisation with the crawler. The longer the forward
button is pressed the faster the crawler will move, press stop to halt the crawler
In reverse the Drum will pull the crawler back, in this mode the crawler
disconnects its wheel drives to allow it to be pulled. The longer the reverse
button is pressed the faster the crawler will move, press stop to halt the crawler.
In reverse the drum can provide a lot of pulling force so ensure the drum is
placed so that it cannot move or be pulled into a culvert.
In normal use (including transportation between sites) the drum can remain in
Auto.
TENSION
This mode allows the crawler to reverse under its own power and should be
used carefully ensuring the crawler does not run over the cable. This mode can
be used when the crawler needs to be manoeuvred, for instance if the crawler is
blocked by an obstruction when retrieving. This allows the crawler to power itself
over obstruction. In all other circumstances leave the drum in AUTO
DRUM LOCK and MANUAL REWIND
This position is used to lock the drum for transportation and for manually
rewinding the cable after the crawler has been removed or if the crawler battery is
exhausted. With the handle released in the DRUM LOCK position the motor
brakes are automatically applied. When the handle is lifted upwards from Drum
Lock cable will be rewound onto the drum. The further the handle is lifted away
from the DRUM LOCK position the faster the drum will rotate.
Manual Rewind can be used if the crawler has exhausted it’s power and
needs to be retrieved to replace the battery.

FITTING EXTENSIONS AND LIGHTHEAD
FITTING WHEEL EXTENSIONS, LARGE BATTERY AND LIGHTHEAD
The Wheel Extensions, Large Battery and Lighthead are options to allow
surveying larger pipe sizes. The wheels are fitted to the extensions first:
Lay Wheel Extensions so that the wheel axles are upwards
Carefully align wheels and fit with locking bolts using the supplied
wheel tool. These do not have to be fitted with too much force and will
lock into place
Lay the crawler on its side so that three axles are upwards
Align the Extensions with the outer axles and rotate the wheels so
that the axles insert correctly
Fit the ratchet handle to the wheel tool and tighten the single central
bolt ensuring that the extensions are fully inserted onto the axles
Repeat for the other extension
Position the crawler upright
Remove any battery fitted to the crawler
Fit the large Lighthead using the two captive Allen bolts
Slide the Large Battery into position

PREPARING SYSTEM FOR USE
Charging Batteries
Welcome to your T815 Tractor system. Please use these instructions together with
the T804 User Manual for full information on control of the Textwriter, DVR and
other features of the base unit.
Before use it is best practice to charge the two batteries supplied with the
Standard Tractor System. You can use either the mains charger (shown below) or
the DC charger. Connect the charger to the battery before connecting the mains or
DC supply. The charger connector is fitted by aligning the two screws to the two
apertures in the battery and turning clockwise—it will only fit in one orientation.
The LED on the charger shows the state of charge. RED means that the charger
is putting energy into the battery. When the battery is fully charged the LED will
change to GREEN.
If the LED does not show at all something is wrong—check the mains or DC
supply.
