Safety Precautions and Working Techniques

Because an earth auger is a high-torque, gaso line-powered tool, some special safety precau tions must be observed to reduce the risk of per sonal injury.

It is important that you read, fully understand and observe the following safety precautions and warnings. Read the instruction manual and the safety precautions 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 federal, state and local safety regulations, standards and ordinances.

DANGER

Drilling into or contact with electrical wires may cause severe shock, burns or death. See the section "Working Condi tions" below.

WARNING

Striking a hard object in the earth with the turning drill and the resulting slowing or stopping of the auger creates reactive forces. The transfer of rotational (reactive) forces can cause the auger powerhead and handles to rotate suddenly in a counterclockwise direction

BT 130

English

and can result in loss of control or cause the handle frame to hit the operator or throw him to the ground, resulting in serious injury.

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 drilling tool comes in contact with your body, it could cause impact or cut injuries.

Use your earth auger only for drilling holes in soil (with earth auger attachments) or ice (with ice auger attachments).

WARNING

Do not use it for other purposes, since misuse may result in personal injury or property damage, including damage to the machine.

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 earth augers. 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.

Safe use of an earth auger involves 1 the operator 2 the power tool 3 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

Prolonged use of a power tool (or other machines) exposing the operator to vibrations may produce whitefinger disease (Raynaud's phenomenon) or carpal tunnel syndrome.

These conditions reduce the hand's ability to feel and regulate temperature, produce numbness and burning sensations and may cause nerve and circulation damage and tissue necrosis.

All factors which contribute to whitefinger disease are not known, but cold weather, smoking and diseases or physical conditions that affect blood vessels and blood transport, as well as high vibration levels and long periods of exposure to vibration are mentioned as factors in the development of whitefinger disease. In order to reduce the risk of whitefinger disease and carpal tunnel syndrome, please note the following:

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

BT 130

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 power tool.

English

Most STIHL power tools are available with an anti-vibration ("AV") system designed to reduce the transmission of vibrations created by the machine to the operator's hands. An AV system is recommended for those persons using power tools on a regular or sustained basis.

– Wear gloves and keep your hands

warm.

– Keep the AV system well

maintained. A power tool with loose components or with damaged or worn AV elements will tend to have higher vibration levels.

– Maintain a firm grip at all times, but

do not squeeze the handles with constant, excessive pressure. Take frequent breaks.

All the above-mentioned precautions do not guarantee that you will not sustain whitefinger disease or carpal tunnel syndrome. Therefore, continual and regular users should closely monitor the condition of their hands and fingers. If any of the above symptoms appear, seek medical advice immediately.

WARNING

The ignition system of the STIHL unit produces an electromagnetic field of a very low intensity. This field may interfere with some pacemakers. To reduce the risk of serious or fatal injury, persons with a pacemaker should consult their physician and the pacemaker manufacturer before operating this tool.

Proper Clothing

WARNING

To reduce the risk of injury, the operator should wear proper protective apparel.

WARNING

To reduce the risk of injury to your eyes never operate your power tool unless wearing goggles or properly fitted protec tive glasses with adequate top and side protection complying with ANSI Z87 "+" (or your applicable national standard).

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.

Clothing must be sturdy and snug-fitting, but allow complete freedom of movement. Wear overalls or 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 be drawn into the drilling tool. Secure hair so it is above shoulder level.

Good footing is very important. Wear sturdy boots with nonslip soles. Steel-toed safety boots are recommended.

Wear an approved safety hard hat to reduce the risk of injury to your head when there is a danger of head injuries.

Always wear heavy duty work gloves (e.g. made of leather or other wear resistant material) when handling the machine and the drilling tool. Heavy-duty, nonslip gloves improve your grip and help to protect your hands.

THE POWER TOOL

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 or expressly approved by STIHL for use with the specific STIHL model are authorized. Although certain unauthorized attachments, drills and

BT 130

English

augers are useable with STIHL power tools, their use may, in fact, be extremely dangerous.

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

Transporting the Power Tool

WARNING

Always stop the engine before putting the earth auger down or carrying it. Carrying an earth auger with the engine running is dangerous. Accidental acceleration of the engine can cause the drilling tool to rotate.

WARNING

During operation, the powerhead muffler and the parts around it reach extremely high temperatures. Avoid setting down a hot unit onto dry, flammable material, or touching the hot muffler; you could receive serious burns.

Carry the unit by the handle frame with hot parts of the machine (e.g., gearbox) away from your body.

Remove the auger before transporting the power tool long distances.

When transporting in a vehicle, properly secure your power tool to prevent turnover, fuel spillage and damage.

When the power tool is not in use, shut it off and put it down so it cannot endanger others.

Fuel Your STIHL power tool uses an oil-

gasoline mixture for fuel (see the chapter on "Fuel" of your instruction manual).

WARNING

Gasoline is an extremely flammable fuel. If spilled and ignited by a spark or other ignition source, it can cause fire and seri ous burn injury or property damage. Use extreme caution when handling gasoline or fuel mix. Do not smoke or bring any fire or flame near the fuel or the power tool. Note that combusti ble fuel vapor may escape from the fuel system.

Fueling Instructions

WARNING

Fuel your power tool in well-ventilated areas, outdoors. Always shut off the engine and allow it to cool before refueling. Gasoline vapor pressure may build up inside the fuel tank depending on the fuel used, the weather conditions and the tank venting system.

In order to reduce the risk of burns and other personal injury from escaping gas vapor and fumes, remove the fuel filler cap on your power tool carefully so as to allow any pressure build-up in the tank to release slowly. Never remove the fuel filler cap while the engine is running.

Select bare ground for fueling and move at least 10 feet (3 m) from the fueling spot before starting the engine. Wipe off any spilled fuel before starting your machine.

WARNING

Check for fuel leakage while refueling and during operation. If fuel leakage is found, do not start or run the engine until the leak is fixed and any spilled fuel has been wiped away. Take care not to get fuel on your clothing. If this happens, change your clothing immediately.

Screw Cap

WARNING

Unit vibrations can cause an improperly tightened fuel filler cap to loosen or come off and spill quanti ties of fuel. In order to reduce the risk of fuel spillage and fire, tighten the fuel filler cap by hand as securely as possible.

See "Fueling" chapter in your instruction manual.

Before Starting

WARNING

Always check your power tool for proper condition and operation before starting, particularly the throttle trigger, throttle trigger lockout, slide control, drilling tool and auger brake. The throttle trigger must move freely and always spring back to the idle position. Never attempt to modify the controls or safety devices. Regular maintenance is important in this respect. Make sure the drilling tool is in good condition and properly connected.

WARNING

Check fuel system for leaks, especially the visible parts, e.g., filler cap, hose connections, manual fuel pump (only for power tools equipped with a manual fuel pump). Do not start the engine if there are leaks or damage – risk of fire! Have the machine repaired by a servicing dealer before using it.

WARNING

Never operate your power tool if it is damaged, improperly adjusted or maintained, or not completely or securely assembled.

WARNING

Check that the spark plug boot is securely mounted on the spark plug – a loose boot may cause arcing that could ignite combustible fumes and cause a fire.

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.

Auger Brake Your earth auger model is equipped with

an auger brake, which is designed to reduce the risk of injury from reactive forces by stopping the rotation of the auger / powerhead when the brake activating lever is engaged. It should also be used during starting and when unwinding a trapped auger. See the chapter on "Auger Brake" for information on engagement of the brake.

Starting Start the engine at least 10 feet (3 m)

from the fueling spot, outdoors only.

For specific starting instructions, see the appropriate section of your manual. Place the power tool on firm ground or

other solid surface in an open area. Maintain good balance and secure footing.

WARNING

Your earth auger should be started only when it is held steady by the operator.

WARNING

To reduce the risk of loss of control, be sure that the auger brake is engaged. When the engine starts at starting throttle, engine speed will be fast enough for the clutch to engage and, if the auger brake is not engaged, turn the drilling 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 speed.

WARNING

Your power tool is a one-person machine. Do not allow other persons in the general work area, even when starting.

WARNING

When you pull the starter grip, do not wrap the starter rope around your hand. Do not let the grip snap back, but guide the starter rope to rewind it properly. Failure to follow this procedure may result in injury to your hand or fingers and may damage the starter mechanism.

BT 130

9912BA000 KN

Important Adjustments

WARNING

To reduce the risk of personal injury from loss of control or contact with the turning drilling tool, do not use your unit with incorrect idle adjustment. At correct idle speed, the drilling tool should not move. For directions on how to adjust idle speed, see the appropriate section of your instruction manual.

If you cannot set the correct idle speed, have your STIHL dealer check your power tool and make proper adjustments and repairs.

During Operation Holding and Controlling the Power Tool Always hold the unit firmly with both

hands on the handles while you are working. Wrap your fingers and thumbs around the handles.

Keep your hands in this position to have your earth auger under control at all times.

Select drilling angle so that the auger brake lever is always in a position to be activated by the operator’s left thigh.

WARNING

Do not overreach. Keep proper footing and balance at all times. Special care must be taken in slippery conditions (wet ground, snow, ice) and in difficult, overgrown terrain. Watch for hidden obstacles such as tree stumps, roots and ditches to avoid stumbling. For better footing, clear away fallen branches, scrub and cuttings. Be extremely cautious when working on slopes or uneven ground or when working with an ice auger attachment on ice.

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

As soon as the engine is running, this product gen erates toxic exhaust fumes containing chemi

cals, such as unburned hydrocarbons (including benzene) and carbon monoxide, that are known to cause respira

tory problems, cancer, birth defects, or other reproductive harm. Some of the gases (e.g. carbon monoxide) may be color less and odorless. To reduce the risk of serious or fatal injury/illness from inhaling toxic fumes, never run the machine indoors or in poorly venti lated locations.

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

BT 130

English

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.

Striking something hard in the earth, such as a rock or gravel, may cause the drilling tool to slow down suddenly or stop. In such a situation, some or all of the rotational force (reactive force) is trans ferred to the powerhead and handle frame of the earth auger which can cause the auger power head and handles to rotate suddenly in a counterclockwise direction.

WARNING

Work carefully in rocky ground or where other solid objects may be present. Keep throttle feed pressure to a minimum. If you feel or hear the drilling tool strike a solid object, release the throttle trigger immediately and remove the object before drilling is continued. When drilling in heavy clay soil, bore about 1/3 way and remove the auger from the hole. Clean off auger drilling tool then continue in slow steps frequently clearing tool.

WARNING

You should hold your earth auger firmly to control sudden jolts and reactive forces. Be prepared to release the

throttle completely if the forces become too great. If reactive forces are not controlled, rotation of the handles may result in severe jerking and loss of control and may cause the handle frame to strike you or throw you to the ground. Your earth auger model is equipped with an auger brake. If the auger hits something it cannot drill through and the powerhead begins to rotate so that the auger brake activating lever strikes the operator’s thigh and engages, the brake is designed to stop the rotation of the powerhead.

WARNING

In order to reduce the risk of serious or fatal injury from reactive forces, never operate your earth auger without a properly functioning auger brake.

If the auger becomes trapped in the drillhole, turn off the engine immediately and remove as described in the chapter entitled "Releasing a Trapped Auger."

DANGER

Contact with electrical cables or wires can cause serious injury or death as a result of elec trical shock. This unit is not insulated.

WARNING

To reduce the risk of electrocution and damage to property, always be alert for underground pipes and cables and for overhead wires. Before drilling, obtain the necessary plans and permits. Contact your local utility company or your locator service, such as "Miss

Utility" or "One Call," for information as to cable and pipe locations. Where necessary, confirm actual location by use of devices such as cable detectors and/or by carefully dug trenches. Stay clear of overhead electrical wires when backing the drilling tool out of the hole. If any portion of the machine strikes a wire, it will cause electrical shock and serious injury or death.

WARNING

Before working with an ice auger attachment on frozen ponds, lakes or streams, check with local authorities and take all necessary precautions to ensure safe ice thickness.

WARNING

Thrown objects may ricochet and strike the operator.

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 to 0 or STOP.

WARNING

When taking the drilling tool out of the hole, lift the machine vertically so that the tool comes out straight without canting. To minimize splashing when drilling ice holes, back off the throttle when the drilling tool breaks through the

BT 130

English

ice. Raise the unit slowly. Cover and clearly mark boreholes to prevent anyone from stepping in a hole.

WARNING

To reduce the risk of injury, never touch a drilling tool or drilling spindle with your hand or any part of your body when the engine is running or the drilling tool is rotating. It continues to rotate for a short period after the throttle trigger is released. Always shut off the engine before putting the machine down.

WARNING

Drilling tool blades and point are sharp. To reduce the risk of cut injuries, use caution when operating and handling.

MAINTENANCE, REPAIR AND STORING

Maintenance, replacement, or repair of the emission control devices and systems may be performed by any nonroad engine repair establishment or individual. However, if you make a warranty claim for a component which has not been serviced or maintained properly or if nonapproved replacement parts were used, STIHL may deny coverage.

WARNING

Use only identical STIHL replacement parts for maintenance and repair. Use of non-STIHL parts may cause serious or fatal injury.

Strictly follow the maintenance and repair instructions in the appropriate section of your instruction manual. Please refer to the maintenance chart near the end of this manual.

WARNING

Always stop the engine before doing any maintenance or repair work or cleaning the power tool.

WARNING

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

Never test the ignition system with the spark plug boot removed from the spark plug or with a removed spark plug, since uncontained sparking may cause a fire.

WARNING

Use the specified spark plug and make sure it and the ignition lead are always clean and in good condition. Always press spark plug boot snugly onto spark plug terminal of the proper size. (Note: If terminal has detachable SAE adapter nut, it must be securely attached.) A loose connection between spark plug terminal and the ignition wire connector in the boot may create arcing that could ignite combustible fumes and cause a fire.

WARNING

Check condition of drilling tool at regular short intervals. If behavior of tool changes, check immediately for tightness or any signs of cracks in particular.

WARNING

Wear gloves when handling or performing maintenance on auger drilling tools.

WARNING

Replace damaged drilling tools immediately, even if they have only superficial cracks. Never attempt to repair damaged drilling tools.

WARNING

Do not operate your power tool if the muffler is damaged, missing or modified. An improperly maintained muffler will increase the risk of fire and hearing loss. Your muffler is equipped with a sparkarresting screen to reduce the risk of fire; never operate your power tool if the screen is missing, damaged or clogged. Remember that the risk of a brush or forest fire is greater in hot or dry weather.

In California, it is a violation of § 4442 or

§ 4443 of the Public Resources Code to use or operate gasoline-powered tools on forest-covered, brush-covered or grass-covered land unless the engine’s exhaust system is equipped with a complying spark arrester that is maintained in effective working order. The owner/operator of this product is responsible for properly maintaining the

Adjusting the Throttle Cable

The correct throttle cable setting is a prerequisite for the correct operation of the warm start, idling and full throttle.

Only set the throttle cable when the machine is fully installed – the control handle must be in the working position.

N Use a tool to press the detent on the

control handle onto the end of the groove

N Open the throttle trigger lockout (1)

and throttle trigger (2) wide (full throttle setting) – this sets the throttle cable properly

4-MIX Engine Fuel

The STIHL 4-MIX engine features mixture lubrication and must be run on a fuel mixture of gasoline and engine oil.

It operates otherwise on the 4-stroke principle.

This engine is certified to operate on unleaded gasoline and the STIHL twostroke engine oil at a mix ratio of 50:1.

Your engine requires a mixture of highquality gasoline and two-stroke air cooled engine oil.

Use mid-grade unleaded gasoline with a minimum octane rating of 89 ((R+M)/2) and no more than 10% ethanol content.

Fuel with a lower octane rating may increase engine temperatures. This, in turn, increases the risk of piston seizure and damage to the engine.

The chemical composition of the fuel is also important. Some fuel additives not only detrimentally affect elastomers (carburetor diaphragms, oil seals, fuel lines, etc.), but magnesium castings and catalytic converters as well. This could cause running problems or even damage the engine. For this reason STIHL recommends that you use only high-quality unleaded gasoline!

Gasoline with an ethanol content of more than 10% can cause running problems and major damage in engines and should not be used.

The ethanol content in gasoline affects engine running speed – it may be necessary to readjust the carburetor if you use fuels with various ethanol contents.

BT 130

WARNING

To reduce the risk of personal injury from loss of control and/or contact with the running cutting tool, do not use your

English

9912BA006 KN

unit with incorrect idle adjustment. At correct idle speed, the cutting tool should not move.

If your power tool shows an incorrect idle adjustment, have your STIHL dealer check your power tool and make proper adjustments and repairs.

The idle speed and maximum speed of the engine change if you switch from a fuel with a certain ethanol content to another fuel with a much higher or lower ethanol content.

This problem can be avoided by always using fuel with the same ethanol content.

Use only STIHL two-stroke engine oil or equivalent high-quality two-stroke engine oils that are designed for use only in air cooled two-cycle engines.

We rec ommend STIHL HP Ul tra 2-Cycle Engine Oil since it is specially formulated for use in STIHL engines.

Do not use BIA or TCW rated (twostroke water cooled) mix oils or other mix oils that state they are for use in both water cooled and air cooled engines (e.g., outboard motors, snowmobiles, chain saws, mopeds, etc.).

WARNING

Take care when handling gasoline. Avoid direct contact with the skin and avoid inhaling fuel vapor. When filling at the pump, first remove the container from your vehicle and place the container on the ground before filling. To reduce the risk of sparks from static discharge and resulting fire and/or explosion, do not fill fuel containers that are sitting in or on a vehicle or trailer.

The container should be kept tightly closed in order to limit the amount of moisture that gets into the mixture.

The machine‘s fuel tank should be cleaned as necessary.

Fuel mix ages

Only mix sufficient fuel for a few days work, not to exceed 30 days of storage. Store in approved fuel-containers only. When mixing, pour oil into the container first, and then add gasoline. Close the container and shake it vigorously by hand to ensure proper mixing of the oil with the fuel.

Fueling

Before fueling, clean the filler cap and the area around it to ensure that no dirt falls into the tank.

Always thoroughly shake the mixture in the can before fueling your machine.

WARNING

In order to reduce the risk of fire and personal injury from escaping gas vapor and fumes, remove the fuel filler cap carefully so as to allow any pressure build-up in the tank to release slowly.

Operating Instructions Releasing a Trapped Auger

During break-in period

A factory-new machine should not be run at high revs (full throttle off load) for the first three tank fillings. This avoids unnecessary high loads during the break-in period. As all moving parts have to bed in during the break-in period, the frictional resistances in the engine are greater during this period. The engine develops its maximum power after about 5 to 15 tank fillings.

During Operation

After a long period of full throttle operation, allow the engine to run for a short while at idle speed so that engine heat can be dissipated by the flow of cooling air. This protects enginemounted components (ignition, carburetor) from thermal overload.

WARNING

Starting a hole with the shaft extension fitted increases the risk of personal injury because the unit is then at chest height and cannot be controlled properly. For the same reason the shaft extension must be removed before the auger is pulled out of the hole.

If the auger is jammed in the drilling hole

N Switch off the engine immediately N Set the slide control to STOP-0

After Finishing Work

Wait for the engine to cool down. Drain the fuel tank. Store the machine in a dry location. Check the tightness of all accessible screws and nuts (not adjusting screws) at regular intervals and retighten if necessary.

Working with shaft extension (special accessory)

Do not fit the shaft extension until the full length of the auger is in the hole.

N Set the activating lever to A – the

auger brake is activated

N Turn the whole auger

counterclockwise to the left until the auger is released again

N Once the jammed auger is

released, check that the auger brake functions properly – see "Auger brake"

Replacing the Air Filter

If there is a noticeable loss of engine power

N Remove the padding on the handle

frame

N Unscrew the screw (1) and remove

the filter cover (2) – screw is fastened in the filter cover so that it is secured against loss

N Remove coarse dirt from inside the

filter cover (2) and around the air filter (3)

N Remove and examine the air

filter (3) – replace if soiled or damaged

N Fit the air filter (3) N Fit the filter cover (2) N Screw in the screw (1) and tighten N Fit the padding – see “Assembling

the machine”

Engine Management Adjusting the Carburetor

Exhaust emissions are controlled by the design of the fundamental engine parameters and components (e.g. carburation, ignition, timing and valve or port timing) without the addition of any major hardware.

The carburetor of the machine has been adjusted for optimum performance and fuel efficiency in all operating states at the factory.

Setting the idle speed

Engine stops when idling N Turn the idle speed adjusting

screw (LA) slowly clockwise until the engine runs smoothly.

Auger turns when idling N Turn the idle speed adjusting

screw (LA) slowly counterclockwise until the auger stops turning

WARNING

If the auger continues to keep moving in idle even after adjustment, have the machine checked by a servicing dealer.

Spark Plug

If engine is down on power, difficult to start or runs poorly at idling speed, first check the spark plug.

Fit a new spark plug after approx. 100 operating hours or earlier if the electrodes are badly eroded.

Wrong fuel mix (too much engine oil in the gasoline), a dirty air filter and unfavorable running conditions (mostly at part throttle etc.) affect the condition of the spark plug. These factors cause deposits to form on the insulator nose which may result in trouble in operation.

Removing the spark plug

N Set the slide control to STOP-0

Checking the Spark Plug

N Clean dirty spark plug. N Check electrode gap (A) and

readjust if necessary – see chapter "Specifications."

N Use only resistor type spark plugs of

the approved range.

Rectify problems which have caused fouling of spark plug:

– too much oil in fuel mix, – dirty air filter, – unfavorable running conditions, e.g.

operating at part load.
