2) Checking brush spring for proper pressure
Using a spring pressure indicator, push the brush
into the brush holder until its tip protrudes 2 mm
(0.08 in). Then measure the pressure of the brush
spring. If the pressure is less than 2.648 N (270 g,
9.52 oz), replace the brush spring with a new one.
The new spring must have a pressure of 4.609 to
5.786 N (470 to 590 g, 16.58 to 20.81 oz).
