Blade Maintenance - Stanley Labounty MDP Series Safety, Operation & Maintenance

BLADE MAINTENANCE

Wear leather work gloves at all times during
blade maintenance.
1. Remove the blade as shown in Figure 25.
2. Grind all rough edges from each blade and
clean the blade seat.
3. Rotate the blade.
Note: each blade has four edges, as shown in
Figure 27 & Figure 28. each time you rotate the
blade, you use a different edge. Replace blades
when all edges are rounded to .25" radius.
4. Reinstall each blade using 500 Ft. Lbs. (680
N/M) torque on each bolt.
Stay at least 75 Ft. (23 m) when moving.
5. Cycle the jaws closed. Measure the gap between
the upper and lower blade using a feeler gauge. If
the gap is larger than .060", shim the blade.
Shimming the Blades
6. Measure the blade gap.
7. Shim each blade so that the blade gap is
approximately .020"- .030". Fit the shims
between the blade and the blade seat.
Note: Do not shim out a blade more than .125".
Doing so may cause structural damage and will
void the warranty.
