Bearing break-in
With the panels removed, engage the mulcher at
full speed and monitor the bearing temperature
with a temperature gun. The break in process can
take up to 3 hours.
Expect the temperature to rise steadily to
maximum 300ºF (149ºC) and then drop.The break
in period can stop as soon as a temperature drop
is observed.
A steady rise in temperature without drop is
indicative of a bad bearing or bad installation.
