TECHNICAL SERVICE BULLETIN NUMBER PI 3118
Date: June 2001
Model & Serial: THT-2100/THT-2120/THT-2510/THT-2520/THT-2540/HTD-2522PF/HTD-2526PF/HTD-
2530PF/HTS-2530PF.
All units produced after serial number W100101.
Reason: When these units are fitted with the aluminum safety shield, some experience
loosening of the blade jam nuts. A flat washer has been added between the nut
and the aluminum shield to help prevent the nut from becoming loose.
Models THT-2100, 2120, 2510 and HTD-2526PF, 2522PF require 3 washers.
Models THT-2520, 2540 and HTS-2530PF and HTD-2530PF require 2 washers

TECHNICAL SERVICE 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.
