GOOD GREASE!

Following the recommended greasing intervals in the service schedule found in your Trimax operator manual will
maximize the life of your bearings and bushes.

TOO MUCH OF A GOOD THING…
You may think you’re doing your mower a favor by applying more grease than the service guide specifies, but excess grease can actually cause problems
with your bearings by dislodging the bearing seals. This can allow water or dirt into your bearing and decrease its service life.

RECOGNIZING BEARING FAILURE

Bearings should allow for smooth, easy rotation. If you feel roughness or tightness when moving a part on a bearing or bush, it could be due to
bearing or bush damage. Dismantle, clean, and inspect the bearing, and replace it if necessary.
While an effective bearing makes rotational movement easier and smoother, it should not allow for much sliding or side-to-side movement.
Excessive play in the bearing can cause damage not only to the bearing itself but also to the rotating parts. To check for play, grasp the part and move
it firmly from side to side across the center of rotation. If there is more than 1/16” (1 mm) of side-to-side movement, then the bearing may be worn or
need adjusting. Dismantle, clean, and inspect the bearing, and replace it if necessary.
