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.
