4. Zero the instrument BEFORE pumping by pressing the

5. Prime the pump slowly until the displayed reading approaches
the priming pressure. The priming pressure is the point that the
instrument begins calculating and displaying the pull rate

the ability to store readings is enabled. Priming pressures for
the various dolly diameters are:
10 mm
14 mm
20 mm
50 mm
50 mm x 50 mm
For optimum results, prior to exceeding the priming pressure,
return the pump handle to its full upright position and then
complete a single continuous stroke at the desired pull rate until
the actuator separates the dolly from the coating.
6. Open the pressure relief valve and remove the dolly from the
actuator assembly.
