Checking Brake Pads

1. Park the machine safely. (See Parking Safely in SAFETY.)

   CAUTION: The machine can fall or slip from an unsafe lifting device or supports.

   • Use a safe lifting device rated for the load to be lifted.
   • Lower machine onto jack stands or other stable supports and block wheels before servicing.
   
   

   IMPORTANT: Place jack stands under frame, not under transmission or engine, when raising or supporting machine.

2. Raise machine with a safe lifting device and lower machine onto jack stands or other stable supports. Block wheels remaining on the ground to prevent machine movement.
