BLADE MAINTENANCE
Before performing blade maintenance, position the attachment on the ground, so that the items being maintained are
close to the ground. When performing maintenance on the upper jaw curl the attachment under the stick.
Wear personal protection equipment at all times. This
includes eye protection, hard hat, steel toe shoes,
leather gloves and hearing protection.
Blades are very heavy. Do not remove a blade if it’s not
supported. The blade may fall and cause injury.
1.
Remove the blade bolts and remove the blade from the blade seat.
Note: Bolts may need to be removed by metal arc gouging.
2.
Ensure the blade seat is clean.
3.
Insert a new blade into the blade seat.
4. Insert the blade bolts and torque as specified in “Inspect / Torque Bolts” on page 18.
