Introduction
These are instructions to convert a grass trimmer to a
blade capable unit. This is not an Owner’s/Operator’s
manual. Information on how to operate and maintain
the unit can be found in the Owner’s/Operator’s man-
ual for the unit you are converting. This kit contains
a cutting attachment shield that has been redesigned
to provide better visibility and a larger cutting swath
when used as a grass trimmer.
Procedure
Remove The Existing Cutting Attachment Shield
1. Align locking hole (A) in adapter plate with
notch in edge of gear case and insert locking
tool (A).
2. Insert locking tool (B).
3. Turn line head (C) clockwise to remove it from
the shaft. Remove the locking tool.
4. Remove shield plate screws (D), shield plate (E),
plastic shield (F), and adapter plate (G). Retain
parts for conversion back to nylon line head op-
eration.
Remove The Gear Case
1. Remove gear case locating screw (H), loosen
gear case clamp bolt(s) (I), remove the gear case

Balance The Unit
Adjust the postion of the harness hangar so the unit
balances two to three inches above the cutting surface.
Use of the Shoulder/Waist Harness is recommended
for all Trimmer/Brushcutter use, not just Blade oper-
ation. The Shoulder/Waist Harness when used in a
trimming operation with nylon line head suspends the
trimmer from the operator’s shoulder and reduces op-
erator fatigue.
During blade operation, the same fatigue reduction is
achieved. Safety to the operator is also enhanced by
reducing the possibility of blade contact with the opera-
tor’s hands and feet by restricting trimmer movement..
