SHOULDER STRAP ASSEMBLY

with the engine completely stopped beforeus-
ing unit. The shoulder strap clamp must be
installed as shown above the handlebar on the
upper shaft (powerhead end of unit).

two spacer tabs attached. These tabs are pro-
vided to adapt this attachment for use with
powerheads that have a 1" (2.5 cm) diameter
upper shaft (the shoulder strap clamp will not
tighten down securely on the 1" (2.5 cm) diam-
eter upper 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 powerheads with a 7/8"
(2.2 cm) upper shaft.
