Safety Precautions and Working Techniques
Because a MultiEngine (YARD BOSS®) equipped with a trimmer attachment is a high-speed power tool, special safety precautions must be observed to reduce the risk of personal injury.
It is important that you read, fully understand and observe the following safety precautions and warnings. Read the instruction manuals and the safety precautions of your MultiEngine and MultiTool periodically. Careless or improper use may cause serious or fatal injury.
Have your STIHL dealer show you how to operate your power tool. Observe all applicable local safety regulations, standards and ordinances.
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 deflector for the type of cutting attachment you are using. Use only cutting attachments that are specifically authorized by STIHL for use on your MultiEngine model.
WARNING
Do not lend or rent your power tool without the instruction manuals of your MultiEngine and MultiTool. Be sure that anyone using it understands the information contained in these manuals.
WARNING
The use of this machine may be hazardous. If the rotating line or polymer 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 polymer 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.
Use your MultiEngine equipped with the appropriate MultiTool only for cutting grass.
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 power tools. Different models may have different parts and controls. See the appropriate section of your MultiEngine and MultiTool instruction manuals for a description of the controls and the function of the parts of your model.
Safe use of a power tool involves
- the operator
- the power tool
- the use of the power tool.
THE OPERATOR
Physical Condition
You must be in good physical condition and mental health and not under the influence of any substance (drugs, alcohol, etc.) which might impair vision, dexterity or judgment. Do not operate this machine when you are fatigued.
WARNING
Be alert – if you get tired, take a break. Tiredness may result in loss of control. Working with any power tool can be strenuous. If you have any condition that might be aggravated by strenuous work, check with your doctor before operating this machine.
English
Proper Clothing
WARNING
To reduce the risk of injury, the operator should wear proper protective apparel.
The deflector provided with your power tool will not protect the operator from all foreign objects (gravel, glass, wire, etc.) thrown back by the rotating cutting attachment. Thrown objects may also ricochet and strike the operator.
WARNING
Clothing must be sturdy and snug-fitting, but allow complete freedom of movement. Wear long pants made of heavy material to help protect your legs. Do not wear shorts, sandals or go barefoot.
Avoid loose-fitting jackets, scarfs, neckties, jewelry, flared or cuffed pants, unconfined long hair or anything that could become caught on branches, brush or the moving parts of the unit. Secure hair so it is above shoulder level.
To reduce the risk of injury to your eyes never operate your power tool unless wearing goggles or properly fitted protective glasses with adequate top and side protection complying with ANSI Z87 "+" (or your applicable national standard). To reduce the risk of injury to your face STIHL recommends that you also wear a face shield or face screen over your goggles or protective glasses.
Power tool noise may damage your hearing. Wear sound barriers (ear plugs or ear mufflers) to protect your hearing. Continual and regular users should have their hearing checked regularly.
Be particularly alert and cautious when wearing hearing protection because your ability to hear warnings (shouts, alarms, etc.) is restricted.
Always wear heavy duty work gloves (e.g. made of leather or other wear resistant material) when handling the cutting attachment. Heavy-duty, nonslip gloves improve your grip and help to protect your hands.
Good footing is very important. Wear sturdy boots with nonslip soles. Steel-toed safety boots are recommended.
For further instructions on proper clothing see the safety precautions in the instruction manual of the MultiEngine you are using.
THE POWER TOOL (MULTIENGINE EQUIPPED WITH TRIMMER MULTITOOL)
For illustrations and definitions of the power tool parts see the chapter on "Main Parts."
WARNING
Never modify this power tool in any way. Only attachments supplied by STIHL and expressly approved by STIHL for use with the specific STIHL MultiEngine are authorized. Although certain unauthorized attachments are useable with STIHL power tools, their use may, in fact, be extremely dangerous.
For the cutting attachments authorized by STIHL for your unit, see the chapter "Approved Combinations of Cutting Attachment and Deflector" in the instruction manual or the STIHL "Cutting Attachments, Parts & Accessories" catalog.
If this tool is subjected to unusually high loads for which it was not designed (e.g. heavy impact or a fall), always check that it is in good condition before continuing work. Check in particular that the fuel system is tight (no leaks) and that the controls and safety devices are
working properly. Do not continue operating this machine if it is damaged. In case of doubt, have it checked by your STIHL servicing dealer.
THE USE OF THE POWER TOOL (MULTIENGINE EQUIPPED WITH TRIMMER MULTITOOL)
Transporting the Power Tool
WARNING
To reduce the risk of injury from loss of control and line contact, never carry or transport your power tool with the cutting attachment moving.
WARNING
Always switch off the engine and make sure the working tool has stopped before putting a power tool down.
natural_image

WARNING
To reduce the risk of burn injury, do not touch hot parts of the machine and the gear housing when they are hot.
WARNING
When transporting it in a vehicle, properly secure it to prevent turnover, fuel spillage and damage to the unit.
Before Starting
WARNING
Always check your power tool for proper condition and operation before starting. Never attempt to modify the controls or safety devices.
WARNING
Never use a power tool that is damaged or not properly maintained.
WARNING
Do not attach any cutting attachment to a unit without proper installation of all required parts. Failure to use the proper parts may cause a blade or head to fly off and seriously injure the operator or bystanders.
WARNING
The cutting attachment must be properly tightened and in safe operating condition. Inspect for loose parts (nuts, screws, etc.) and for cracked or damaged heads. Replace damaged heads before using the power tool.
Keep the handles clean and dry at all times; it is particularly important to keep them free of moisture, pitch, oil, fuel mix, grease or resin in order for you to maintain a firm grip and properly control your power tool.
WARNING
To reduce the risk of personal injury to the operator from polymer blade or line contact and thrown objects, make sure your unit is equipped with the proper deflector for the type of cutting attachment being used (see chart in the chapter on "Approved Combinations of Cutting Attachment and Deflector".)
Keep the deflector adjusted properly at all times (see chapters on "Mounting the Deflector" and "Mounting the Cutting Attachment" of your instruction manual).
natural_image
Technical line drawing of a mechanical component with no visible text or symbolsArrows on the deflector (A) (as seen from the top) show the correct direction of rotation of the cutting attachment. When viewed from above, however, the cutting attachment rotates counterclockwise.
English
Starting
WARNING
Start the engine at least 10 feet (3 m) from the fueling spot, outdoors only.
Start and operate your power tool without assistance. For specific starting instructions, see the appropriate section of your MultiEngine and MultiTool manuals. Place the power tool on firm ground or other solid surface in an open area. Maintain good balance and secure footing.
WARNING
To reduce the risk of injury from loss of control, be absolutely sure that the working tool is clear of you and all other obstructions and objects, including the ground, because when the engine starts at starting-throttle, engine speed will be fast enough for the clutch to engage and move the working tool.
Once the engine has started, immediately blip the throttle trigger, which should release the starting throttle and allow the engine to slow down to idle.
WARNING
Your power tool is a one-person machine. Do not allow other persons in the general work area, even when starting.
See also the safety precautions on Starting in the instruction manual of the MultiEngine.
Set of wheels
natural_image
Technical line drawing of a mechanical device with levers and gears (no text or symbols)Use the MultiTool on the MultiEngine only in combination with a set of wheels (special accessory).
Use only genuine STIHL wheels. The use of other wheels may result in damage to the machine or personal injury.
The wheels can be locked in different positions - see notes on "Wheels" in the MultiEngine instruction manual.
During Operation
Holding and Controlling the Power Tool
natural_image
Line drawing of a person holding a medical device with a strap (no text or symbols)Always hold the unit firmly with both hands on the handles while you are working. Wrap your fingers and thumbs around the handles.
WARNING
Never attempt to operate your power tool with one hand. Loss of control of the power tool resulting in serious or fatal injury may result. To reduce the risk of cut injuries, keep hands and feet away from the cutting attachment. Never touch a moving cutting attachment with your hand or any other part of your body.
WARNING
Do not overreach. Keep proper footing and balance at all times. Special care must be taken in slippery conditions (wet ground, snow) and in difficult, overgrown terrain. Watch for hidden obstacles such as tree stumps, roots and ditches to avoid stumbling. For better footing, clear
away scrub and cuttings. Be extremely cautious when working on slopes or uneven ground.
WARNING
To reduce the risk of injury from loss of control, never work on any other insecure support. Never hold the cutting attachment above waist height
Working Conditions
Operate and start your power tool only outdoors in a well-ventilated area. Operate it under good visibility and daylight conditions only. Work carefully.
WARNING
If the vegetation being cut or the surrounding ground is coated with a chemical substance (such as an active pesticide or herbicide), read and follow the instructions and warnings that accompany the substance at issue.
WARNING
Inhalation of certain dusts, especially organic dusts such as mold or pollen, can cause susceptible persons to have an allergic or asthmatic reaction. Substantial or repeated inhalation of dust and other airborne contaminants, in particular those with a smaller particle size, may cause respiratory or other illnesses. Control dust at the source where possible. Use good work practices, such as operating the unit so that the wind or operating process directs any dust raised by the power tool away from the operator. Follow the recommendations of EPA / OSHA / NIOSH and occupational and trade associations with respect to dust
("particulate matter"). When the inhalation of dust cannot be substantially controlled, i.e., kept at or near the ambient (background) level, the operator and any bystanders should wear a respirator approved by NIOSH / MSHA for the type of dust encountered.
Operating Instructions
WARNING
Do not operate your power tool using the starting throttle lock, as you do not have control of the engine speed.
In the event of an emergency, switch off the engine immediately – move the slide control / stop switch to 0 or STOP.
WARNING
The cutting attachment continues to rotate for a short period after the throttle trigger is released (flywheel effect.)
The rotating cutting attachment may fling foreign objects directly or by ricochet a great distance.
To reduce the risk of eye and other injury always wear proper eye protection (see the chapter on "Proper Clothing") and ensure that bystanders are at least 50 feet (15 m) away. To reduce the risk of damage to property, also maintain this distance from such objects as vehicles
or windows. Even maintaining a minimum distance of 15 meters cannot exclude the potential risk. Any coworkers who must be in the restricted area should also wear goggles or protective glasses. Stop the engine immediately if you are approached.
WARNING
Inspect the work area: To reduce the risk of injury, remove stones, pieces of metal and other solid objects which could be thrown 50 feet (15 m) or more by the cutting attachment or damage the cutting attachment and property (e.g. parked vehicles, windows).
WARNING
This power tool is normally to be used at ground level with the MultiTool parallel to the ground. Use of a MultiEngine above ground level or with the MultiTool perpendicular to the ground may increase the risk of injury, since the cutting attachment is more fully exposed and the power tool may be more difficult to control.
WARNING
During cutting, check the tightness and the condition of the cutting attachment at regular short intervals with the engine and attachment stopped. If the behavior of the attachment changes during use, stop the engine immediately, wait until the cutting attachment stops, and check
English
the nut securing the attachment for tightness and the attachment for cracks, wear and damage.
WARNING
A loose head may vibrate, crack, break or come off the power tool, which may result in serious or fatal injury. Make sure that the cutting attachment is properly tightened. Use the wrench supplied or one of sufficient length to obtain the proper torque. If the head loosens after being properly tightened, stop work immediately. The retaining nut may be worn or damaged and should be replaced. If the head continues to loosen, see your STIHL dealer. Never use a MultiEngine with a loose MultiTool.
WARNING
Replace a cracked, damaged or worn-out head immediately, even if damage is limited to superficial cracks. Such attachments may shatter at high speed and cause serious or fatal injury.
WARNING
If the head or deflector becomes clogged or stuck, always shut off the engine and make sure the cutting attachment has stopped before cleaning. Grass, weeds, etc. should be cleaned off from around the head at regular intervals.
WARNING
To reduce the risk of unintentional rotation of the cutting attachment and injury, always shut off the engine before replacing the cutting attachment. To
reduce the risk of injury, always shut off the engine before adjusting the length of the nylon line on manually adjustable mowing heads.
WARNING
The gearbox becomes hot during operation. To reduce the risk of burn injury, do not touch the gear housing when it is hot.
USING THE CUTTING ATTACHMENT
For an illustration of the various cutting attachments and instructions on proper mounting see the chapter on "Mounting the Cutting Attachment" in your instruction manual.
WARNING
To reduce the risk of severe or fatal injury from blade contact and / or loss of control, never attempt to use a metal blade on a power tool for which it is not authorized.
Using the Mowing Heads
Do not use with mowing line longer than the intended length. With a properly mounted deflector, the built-in line-limiting blade will automatically adjust the line to its proper length.
Using the unit with an overly long nylon cutting line increases the load on the engine and reduces its operating speed. This causes the clutch to slip continuously and results in overheating and damage to important components (e.g. clutch, polymer housing
components). Such damage could, among other things, cause the cutting attachment to rotate at idle.
Mowing heads are to be used only on trimmers / brushcutters equipped with a line-limiting blade in the deflector in order to keep the line at the proper length (see "Main Parts" chapter in your instruction manual).
If the lawn edges are planted with trees or bordered by a fence etc., it is best to use a nylon line head. It achieves a "softer" cut with less risk of damaging tree bark etc. than polymer blades.
However, the polymer-bladed STIHL PolyCut produces a better cut if there are no plants along the edge of the lawn. Sharpening is not necessary, and worn polymer blades are easily replaced.
WARNING
To reduce the risk of serious injury, never use wire or metal-reinforced line or other material in place of the nylon cutting lines. Pieces of wire could break off and be thrown at high speed toward the operator or bystanders.
STIHL SuperCut mowing head
Fresh line is advanced automatically. Frayed line is replaced by a simple adjustment (see instruction sheet supplied with mowing head).
STIHL AutoCut mowing head
Nylon cutting line advances automatically when tapped against the ground (TapAction).
STIHL TrimCut mowing head
Frayed line is replaced by a simple adjustment (see instruction sheet supplied with mowing head).
STIHL PolyCut mowing head
Uses either nylon lines or nonrigid, pivoting polymer blades.
Observe wear indicators.
natural_image
Pure mechanical component diagram without any text, numbers, or symbolsWARNING
Three rectangular wear limit marks are applied to the base (periphery) of the PolyCut. To reduce the risk of serious injury from breakage of the head or blades, the PolyCut must not be used when it has worn as far as one of these marks. It is important to follow the maintenance instructions supplied with the head.
STIHL FixCut mowing head
Uses pre-cut lengths of nylon line.
Observe wear indicators.
Do not continue using the mowing head if the raised moldings (1) on the base are missing or worn – see right illustration above. The mowing head may otherwise shatter, and flying objects could result in injury to the operator or bystanders. Install a new mowing head.
MAINTENANCE, REPAIR AND STORING
WARNING
Always stop the engine and make sure that the cutting attachment is stopped before doing any maintenance or repair work or cleaning the power tool. Do not attempt any maintenance or repair work not described in your instruction manual. Have such work performed by your STIHL servicing dealer only.
WARNING
Use only identical STIHL replacement parts for maintenance and repair. Use of non-STIHL parts may cause serious or fatal injury.
Wear gloves when handling or performing maintenance on blades.
WARNING
Never repair damaged cutting attachments by welding, straightening or modifying the shape. This may cause parts of the cutting attachment to come off and result in serious or fatal injuries.
Tighten all nuts, bolts and screws, except the carburetor adjustment screws, after each use.
Do not clean your machine with a pressure washer. The solid jet of water may damage parts of the machine.
Store the power tool in a dry and high or locked location out of reach of children.

Replacing Nylon Line
Always check the mowing head for signs of wear before replacing the nylon line.
WARNING
If there are signs of serious wear, replace the complete mowing head.
The nylon mowing line is referred to as "nylon line" or "line" in the following.
The mowing head is supplied with illustrated instructions for replacing the nylon line. Keep the instructions for the mowing head in a safe place.
- If necessary, remove the mowing head.
Adjusting Nylon Line
STIHL SuperCut
Fresh line is advanced automatically if the remaining line is at least 6 cm (2 1/2 in) long. The blade on the deflector trims overlong lines to the correct length.
STIHL AutoCut
●With the engine running, hold the rotating mowing head above the grass surface.
- Tap it on the ground once – fresh line is advanced and the blade on the deflector trims it to the right length.
Fresh line is advanced every time the mowing head is tapped on the ground. For this reason observe the mowing head's cutting performance during operation. If the mowing head is tapped on the ground too often, the line limiting blade will unnecessarily cut off unused lengths of nylon line.
Line feed operates only if both lines are still at least 2.5 cm (1 in) long.
Replacing Nylon Line
STIHL PolyCut
Precut lengths of nylon line can be fitted to the PolyCut in place of the cutting blades.
To reduce the risk of injury, always shut off the engine before refilling the mowing head.
●Fit precut lengths of nylon line in the mowing head as described in the instructions supplied.
Replacing Cutting Blades
STIHL PolyCut
Always check the mowing head for signs of wear before installing new cutting blades.
WARNING
If there are signs of serious wear, replace the complete mowing head.
The thermoplastic cutting blades are referred to as "blades" in the following.
The mowing head is supplied with illustrated instructions for replacing the blades. Keep the instructions for the mowing head in a safe place.
WARNING
To reduce the risk of injury, always shut off the engine before installing the blades.
- Remove the mowing head.
