When measuring to the Target Pole:
•
Ensure that the target surface is 'square' to the laser;
•
Check that it is held vertically by using the bubble embedded in the top of the pole – a 1mm
offset of the bubble from the centre of the vial translates approximately to a 0.5mm error in the X-
Y measurement.
The Pointed Foot and Rounded Foot click into the bottom of the Target Pole and are interchangeable.
When using the Target Pole on its own, it is advisable to use the Rounded Foot to minimise wear to
the Pointed Foot (refer to Section 4.2).
When using the Target Pole with the Rail Pole, the Pointed Foot must be fitted. When measuring the
location of an adjacent track, the Rail Pole allows the Pointed Foot to be located accurately on the
gauge corner of the rail.
1.
Place the Rail Pole on the track to be measured;
2.
Ensure that the Rail Pole is located 'squarely' across the track and that it is firmly located
against the rail being measured;
3.
Locate the Pointed Foot in the socket in the Rail Pole.

4.1 Before Each Use
Make sure there are no obstructions in the Rail Pole socket such as dirt.
4.2 Every 3 Months
Visually inspect the ABT4659 for signs of damage. If necessary, contact your local distributor for help.
Check the Pointed Foot and Rounded Foot for wear by measuring the length as shown in figure. The
foot should be replaced if it has worn by more than 1mm.
