Tighten the tensioning screw until the centre of the track deflects by 12mm when lightly
pressed in its centre (see diagram below). Tighten the 6 screws clamping each sprocket
assembly and reinstall the aluminium ring.

Calibrating gas detectors
The sensors should be calibrated in accordance with the instructions of the gas detector’s supplier.
They’re available in the resources section of the ExRobotics’ website.
ExR-1 gas sensors can be accessed via the hatch between the tracks on the left hand side of robots
which is secured with two hexagonal socket-head screws (see picture). ExR-2 gas sensors are
accessed by removing the upper cladding.

Replacing ExR-2 batteries
ExR-
2’s batteries can be replaced by removing the
front hull cladding and the battery pack lid
behind. When replacing the batteries make sure that:
▪
Only batteries supplied by ExRobotics are used. Any other batteries will invalidate the robot’s
Ex certification.
▪
The foam strips around the inside of the battery enclosure remain secure.
▪
The thermal sensors between the batteries and their gap pads are not dislodged.
▪
The bolts connecting the battery leads to the terminals are torqued to 3.6 Nm with a
calibrated torque wrench.
▪
Ty-raps are used to ensure the battery leads and other wires cannot be trapped between two
metal parts.
▪
The bolts on the battery pack lid are re-torqued to 7 Nm with a calibrated torque wrench.
ExRobotics will provide remote support the first time a customer performs this task.
