Preparing Upperstructure for Undercarriage Operation
1. Check operation of brakes after remote operation and digging.
2. Position unit on level surface, apply digging brake and stop engine. Check the
following for damage; brake actuator chambers and rods, brake actuator
brackets, and slack adjusters. With brake applied, actuator rod should form an
approximate right angle with slack adjuster. Do not drive unit until any damage
or malfunction has been repaired. Check for proper slack adjuster operation in
accordance with the procedure shown on page 5-37.
3. Position boom over rear of undercarriage and embed bucket in ground or
against a solid object.
4. Apply down pressure with boom and pull and push with boom while a helper
watches for rotation of each wheel.
5. Rotation of any wheel during step 3 indicates brake failure on that wheel. Have
any failure corrected before driving the unit.
6. Position boom in rest, allowing clearance for attachment. See “Boom Stow
Procedure” on page 3-35. Secure boom using boom hold-down device. See
“Securing Unit for Driving” on page 3-35.
7. Idle engine to remove heat from critical areas.
8. Shut down engine from upperstructure cab.
