Adjusting the Position of the Stop Pin
The position of the stop pin is correctly set at the factory. If the position has to be reset or adjusted due to service or replacement of spare parts, follow the instructions below.
Measurement D is the opening diameter for the gauge.
D = 1.55 mm
Fit a 2.5 mm Allen key in the adjustment screw.
Hold the Pulse unit with both stop surface of inertia body and anvil in horizontal position and the Allen key pointing downwards.
Press the inertia body to open the hole for the gauge.
Place a gauge, for instance a drill bit, with the correct diameter of D in the hole.
Adjust the opening by turning the adjustment screw 45 degrees at the time until the gauge is in line with the pulse unit.
Avoid unnecessary turning of the adjustment screw.
Turn the screw anti-clockwise to raise the gauge.
Turn the screw clockwise to lower the gauge.
Check that the gauge is correctly inserted by repeatedly pressing and releasing the inertia body. The gauge should return to the correct position in line with the Pulse unit.
Apply Loctite 290 to the adjustment screw.
