Strengths

- The manual names two spark plugs with a gap range and sets out a weekly and monthly maintenance schedule for this model.
- Throttle controls sit on the tube with cruise control, and the listing names an adjustable offset handle and an ergonomic harness.
Caveats
- The listing's headline 692 CFM does not appear in Husqvarna's specification table or in the manual, and no measuring point is given for it.
- The listing's Noise Level field reads 692 dB, the same number as its air-flow claim; Husqvarna's figure is 94 dB(A) at the operator's ear.
- The supplied manual covers both the 350BT and the 350BF in one technical data table, so the columns have to be read carefully.
