SHOULDER STRAP ASSEMBLY
WARNING:
Proper shoulder strap and
handle adjustments are required before use.
The shoulder strap clamp must be installed as
shown above the assist handle on the engine
end shaft.
NOTE:
The lower shoulder strap clamp has
two spacer tabs attached. These tabs are
provided to adapt this attachment for use with
units that have a 1 inch (2,5 cm) diameter
shaft (the shoulder strap clamp will not tighten
down securely on the 1 inch (2,5 cm) diameter
shaft without using these spacer tabs). The
tabs must be broken off completely before
use and placed over the screw holes on the
lower shoulder strap clamp. These tabs are
not needed for units with a 7/8
″
(2,2 cm) shaft.
