BULLETIN NUMBER PI 3119

Date:

January, 2002

Model & Serial: All THT, HTD, HTS, TPH hedgetrimmer models.

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.
