What is a FS 90?
FS 90, FS 90 R English 3 The terminology utilized in this manual when referring to the power tool reflects the fact that different types of cutting attachments may be mounted on it. The term "trimmer" is used to designate an FS unit that is equipped with a nylon line head or a head with flexible plastic blades (i.e., the PolyCut head). A "brushcutter" designates a unit equipped with a rigid metal blade. Many FS models may be used as either a trimmer or a brushcutter – therefore, the power tool is referred in this manual as a "trimmer / brushcutter." Some smaller and / or lightweight FS models may only be used as a trimmer, i.e., they may not be used with metal blades. The term "clearing saw" indicates a high-powered trimmer / brushcutter that is particularly suited for use with a circular saw blade to clear saplings or small trees. FS models with an "R" on the nameplate were originally configured (at the time of distribution) as a trimmer with a loop handle. WARNING As more fully explained later in these Safety Precautions, to reduce the risk of personal injury, make sure your unit is equipped with the proper handle, harness and deflector for the type of cutting attachment you are using. Use only cutting attachments that are specifically authorized by STIHL for use on your FS model. Have your STIHL dealer show you how to operate your power tool. Observe all applicable local safety regulations, standards and ordinances. WARNING Do not lend or rent your power tool without the instruction manual. Be sure that anyone using it understands the information contained in this manual. WARNING The use of this machine may be hazardous. If the rotating line or blade comes in contact with your body, it will cut you. When it comes in contact with solid foreign objects such as rocks or bits of metal, it may fling them directly or by ricochet in the direction of bystanders or the operator. Striking such objects could damage the cutting attachment and may cause blades to crack, chip or break. Thrown objects, including broken heads or blades, may result in serious or fatal injury to the operator or bystanders. STIHL does not recommend the use of rigid blades when cutting in stony areas. Use your trimmer / brushcutter equipped with the appropriate cutting attachment only for cutting grass, brush, wood and similar material. WARNING Do not use it for other purposes, since misuse may result in personal injury or property damage, including damage to the machine. WARNING Minors should never be allowed to use this power tool. Bystanders, especially children, and animals should not be allowed in the area where it is in use. WARNING To reduce the risk of injury to bystanders and damage to property, never let your power tool run unattended. When it is not in use (e.g. during a work break), shut it off and make sure that unauthorized persons do not use it. Most of these safety precautions and warnings apply to the use of all STIHL trimmers / brushcutters. Different models may have different parts and controls. See the appropriate section of your instruction manual for a description of the controls and the function of the parts of your model.

How to use a brush knife to cut grass?
The higher the cutting attachment is off the ground, the greater the risk of loss of control and of cuttings being thrown sideways. Use the power tool like a scythe to cut grass, i.e. sweep it to and fro in an arc. WARNING When cutting woody materials, use the left side of the blade to avoid "kickout" (blade thrust) situations. WARNING Improper use of a brush knife may cause it to crack, chip or shatter. Thrown blade fragments may seriously or fatally injure the operator or bystanders. To reduce the risk of injury, avoid contact with hard or solid foreign objects such as stones, rocks or pieces of metal. WARNING When cutting young saplings or other woody materials up to 2cm (3/4 in.) in diameter, use the left side of the blade to avoid "kickout" situations (see section on "Risk of kickout (blade thrust) with all rigid cutting blades"). Do not attempt to cut woody material with a larger diameter, since the blade may catch or jerk the power tool forward. This may cause damage to the blade or power tool or loss of control of the power tool, resulting in personal injury. Use a circular saw blade for such work. WARNING Inspect the brush knife at regular short intervals for signs of damage. Do not continue working with a damaged brush knife. Resharpen the brush knife regularly (when it has dulled noticeably). Using the Circular Saw Blade Circular saw blades are suitable for thinning brush and cutting small trees up to a diameter of 4cm (1 1/2 in.). Do not attempt to cut trees with larger diameters, since the blade may catch or jerk the trimmer / brushcutter forward. This may cause damage to the blade or loss of control of the power tool and result in serious injury. Use a chain saw for such work. WARNING To reduce the risk that the blade will crack and / or break, avoid all contact with stones, rocks or the ground. Sharpen blades in a timely manner as specified – dull teeth may cause the blade to crack or shatter. When a trimmer / brushcutter with a circular saw blade is used to cut down small trees, STIHL recommends that the standard deflector be removed and

Ultimately, between its features, performance, warranty, and price point, we feel that the Stihl FS 91 R presents a really solid value.

The Stihl FS 91 R finished in 7th place here. So, for whatever it’s worth, you’ll have to stop less often for refueling, but you’re not getting the best fuel economy with this model.
