BLADE MAINTENANCE
Before performing blade maintenance, place the attachment on the ground, so that the part being maintained is closest
to the ground. When performing maintenance on the upper jaw curl the attachment under the stick so that the upper
jaw is on the ground.
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.
CRACKER JAW
Measuring Blade Gap and Shimming
Note: Removing and handling blades can be hazardous if done incorrectly.
Stay at least 75 ft. (23 m) when moving.
1. Cycle the tool until the upper jaw blade begins to overlap the lower jaw blade.
2. Measure the blade gap. If the gap is larger than 0.4 mm, add shims between the guide blade and blade seat until the
gap is 0.4 mm - 0.4 mm.
Blade Rotation
Each cracker jaw blade has four edges. Each time you rotate the blade, use a different edge until all the edges are
worn to .25” radius.
