Curl the Shear Under

Figure 20 

Loosening Blades

1. 

Back out the bolts holding the blade in place. Ensure the bolts are still threaded into the blade.

Never strike the blade with a hardened steel tool. The 

blade may chip and cause severe injury.

2. 

If the blades are not loose, tap on the blade face with a soft-faced mallet.

3.  Use a pry bar between the blade and blade seat to loosen the blade.

Do not strike the blade bolts directly with a hammer or 

other hard object. This may cause damage to the blade.

4. 

If the blade is still not loose, place a wood block against the head of one of the blade bolts. Strike it with a mallet.

Bolts are loose, 

but threaded in 

the blade.
