REPLACE BOLT ON CUTTING EDGE 4
WARNING
It is extremely dangerous if the work equipment moves when carrying out the turning or replacement
operation.
Set the work equipment in a stable position, stop the engine, then set the safety lock lever securely to the
LOCK position.
Turn or replace the cutting edge before the wear reaches the edge of the bucket.
1. Raise the bucket to a suitable height, then put blocks (A) under the bucket to prevent the bucket from coming
down.
Raise the bucket so that the bottom surface of the bucket is horizontal.
2. Remove nuts and bolts (1), then remove cutting edge (2).
3. Clean the mounting surface of cutting edge (2).
4. Turn cutting edge (2) and install it to the bucket. When turn-
ing the edge, install it to the opposite side (left edge to right
side, right edge to left side).
If both sides of the cutting edge are worn, replace with a
new part.
If the wear extends to the mounting surface, repair the
mounting surface before installing the cutting edge.
5. Tighten nuts and bolts (1) uniformly so that there is no gap between the bucket and cutting edge.
Tightening torque for mounting bolt: 883 to 1196 N·m (90 to 122 kgf·m, 651 to 882 lbft)
6. Tighten the mounting bolts again after operating for several hours.
