SHOULDER STRAP ASSEMBLY
WARNING: Proper shoulder strap and handlebar adjustments must be made with the engine completely stopped before us- ing unit. The shoulder strap clamp must be installed as shown above the handlebar on the upper shaft (powerhead end of unit).
NOTE: The lower shoulder strap clamp has 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.
