All units after serial number Y004401 

 

 
Reason: 

All future production of hedgetrimmer models will utilize a blade-retaining nut 
that is of the locking variety. These nuts are oblong on one side to prevent 
loosening during use, but can be removed and re-installed without losing their 
locking ability. 

 
 

When adjusting blade-fastening hardware, thread the bolt (18) through the 
blades and guide bar from the bottom, to a point where the flat washer (17), is 
still able to rotate, (usually to seat, and then backed off between ¼ and ½ 
revolution). Then install the lock nuts on the topside, tightening them while 
holding the bolt in place. Tighten all nuts, and then re-check for adjustment prior 
to operation. A lubricating agent, such as WD-40 should also be used to prevent 
sap build-up and premature wear.
