How to Operate A Brushcutter

From pre-use checklists to basic operation techniques and storage tips, STIHL trimmers are known for their ability to cut weeds and overgrown grass, but they can do much more. With optional interchangeable cutting heads, you can turn your STIHL trimmer into a power brushcutting machine.

Pre-Use Checklist

Switch off the engine completely and allow it to cool before refueling.
Check working environment for any hazards.
Keep a safe distance from other people (50 feet or more).
Ensure attachments are mounted correctly and securely.
Adjust the harness and handle(s) to suit your height.

Personal Protective Equipment Checklist

Brush Shield – To help reduce the risk of injury to the head and face, wear a brush shield with built-in hearing protection.
Hearing Protection – To help protect your hearing, wear sound barriers like ear plugs or ear muffs.
Protective Glasses – Protective glasses should be worn under the brush shield as your primary defense against getting wood chips or other particulates in the eyes.
Gloves – To help protect your hands, always wear heavy-duty work gloves made of leather or other wear-resistant material.
Leg Protection – To help protect your legs, wear long pants made of heavy material.
Protective Boots – To help maintain good footing, wear sturdy boots with nonslip soles. Steel-toe safety boots are recommended.

Brushcutter Starting Procedure

Start in a well-ventilated area.
Move at least 10 feet away from your fueling spot.
Press the primer bulb at least 5 times (if unit has a primer bulb).
Use choke if the engine is cold.
Make sure you have secure footing.
Ensure the cutting attachment is not touching anything.
Start your brushcutter.

Because the cutting attachment rotates counter-clockwise, a right-to-left cutting motion is recommended. The advantage of this method is that the trimmings fall on the cut area.

When working in very long grass or tough weeds, two passes are recommended. An initial pass, right to left, cuts the top of the grass. Then, a lower pass, left to right, removes the remaining grass. The trimmings will discard to the left.

The best way to cut large areas is to use the square method. Divide the area to be mown into squares, and then work along the outsides toward the center.

The strip method is a good way to mow a slope. Cut a strip parallel to the slope, and then return along the swath. Then, cut the next strip above and repeat.

The “mowing line” created by the trimmer is the best way of navigating right up to trees or bushes without damaging them. If several plants are growing close together, try to clear around them before mowing. To do that, use the deflector on your brushcutter as a guide. Place the deflector up against the base of the tree or bush and use it to guide you as you move. That protects the trunk while mowing the area around it.

Holding Bike–Handle Brushcutters

SHOULDER HARNESS

When putting on the harness, the spring hook should be about a hand’s width below your right hip.

SUSPENSION EYELET

Suspend the machine from the eyelet using the spring hook.

PROPER BALANCE

Adjust the handles and push the carrying ring along the shaft until the brushcutter is balanced. The cutting attachment should be just above the ground. The optimum cutting angle is automatically achieved when the machine is balanced.

BRUSHCUTTER POSITION

The correct brushcutter position is with your arms slightly bent and your wrists straight. Please refer to your product’s instruction manual for specific tips on using the circular saw blade.

Holding Loop-Handle Trimmers

SHOULDER STRAP

First, put on the shoulder strap and attach the hook to the carrying ring on the machine. The hook should be about a hand’s width below your right hip.
