INTR ODUCTION

Dear customer!

Thank y ou for choosing a McCulloch product. You are thereby part of a story that started long ago, when the McCulloch Corporation started its manufacturing of engines during World War II. In 1949, when McCulloch introduced its ﬁrst light one-man chainsaw, woodworking would never be the same again.

The line of innovative chainsaws would continue over the decades, and business was expanded, ﬁrst by airplane and kart engines in the 1950s, then by mini chainsaws in the 1960s. Later, in the 1970s and 80s, trimmers and blower vacs were added to the range.

Today, as a part of the Husqvarna group, McCulloch continues the tradition of powerful engines, technical innovations, and strong designs that have been our hallmarks for more than half a century. Lowering fuel consumption, emissions and noise levels are of top priority to us, as is improving safety and user-friendliness.

We certainly hope that you will be satisﬁed with your McCulloch product, as it is designed to be your companion for a long time. By following this operators manual’s advice on usage, service, and maintenance, its lifespan can be extended. If you should need professional help with repair or service, please use the Service Locator at www.mcculloch.com.

McCulloch has a policy of continuous product development and therefore reserves the right to modify the design and appearance of products without prior notice.

GENERAL SAFETY PRECAUTIONS

Stop switch

Use the stop switch to switch off the engine.

Start the engine and make sure the engine stops when you move the stop switch to the stop setting. The stop switch automatically returns to the start position. In order to prevent unintentional starting, the spark plug cap must be removed from the spark plug when assembling, checking and/or performing maintenance.

Hand guard

The hand guard prevents hands from coming into contact with the moving blades, for example, if the operator loses grip on the front handle.

Regularly check the vibration damping units for cracks or deformation. Check that the vibration damping element is undamaged and securely attached.

WARNING! Overexposure to vibration can lead to circulatory damage or nerve damage in people who have impaired circulation. Contact your doctor if you experience symptoms of overexposure to vibration. Such symptoms include numbness, loss of feeling, tingling, pricking, pain, loss of strength, changes in skin colour or condition. These symptoms normally appear in the ﬁngers, hands or wrists. The risk increases at low temperatures.

Mufﬂer

The mufﬂer is designed to keep noise levels to a minimum and to direct exhaust fumes away from the user. A mufﬂer ﬁtted with a catalytic converter is also designed to reduce harmful exhaust gases.

In countries that have a warm and dry climate there is a signiﬁcant risk of ﬁre. We therefore ﬁt certain mufﬂers with a spark arrestor screen. Check whether the mufﬂer on your machine is ﬁtted with this kind of screen.

Check that the hand guard is ﬁtted correctly. Check that the hand guard is undamaged.

Vibration damping system

Your machine is equipped with a vibration damping system that is designed to reduce vibration and make operation easier.

The machine′s vibration damping system reduces the transfer of vibration between the engine unit/cutting equipment and the machine

The engine body, including the blades, is suspended on the handlebar using four rubber bushings.

′s handle unit.

For mufﬂers it is very important that you follow the instructions on checking, maintaining and servicing your machine.

Never use a machine that has a faulty mufﬂer.

Regularly check that the mufﬂer is securely attached to the machine.

GENERAL SAFETY PRECAUTIONS

If the mufﬂer on your machine is ﬁtted with a spark arrestor screen this must be cleaned regularly. A blocked screen will cause the engine to overheat and may lead to serious damage.

WARNING! Mufﬂers ﬁtted with catalytic converters get very hot during use and

remain so for some time after stopping. This also applies at idle speed. Contact can result in burns to the skin. Remember the risk of ﬁre!

WARNING! The inside of the mufﬂer contain chemicals that may be

carcinogenic. Avoid contact with these elements in the event of a damaged mufﬂer.

WARNING! Bear in mind that: The exhaust fumes from the engine are hot

and may contain sparks which can start a ﬁre. Never start the machine indoors or near combustible material!

Gear

The gear housing gets hot when the machine has been in use. To avoid burning yourself do not touch the gear housing.

Blade and blade guard

The outer part of the blades (1) are shaped as blade guards. The blade guard is intended to protect against any part of the body coming into contact with the blades.

Check that the blade guard is not damaged or distorted. Replace the cutting unit if it is bent or damaged.

FUEL HANDLING

Fuel safety

Never start the machine: 1 If you have spilled fuel on it. Wipe off the spillage and

allow remaining fuel to evaporate.

2 If you have spilled fuel on yourself or your clothes,

change your clothes. Wash any part of your body that has come in contact with fuel. Use soap and water.

3 If the machine is leaking fuel. Check regularly for

leaks from the fuel cap and fuel lines.

Transport and storage

• Allow the hedge trimmer to cool down after use before putting it away for storage.

• Store and transport the machine and fuel so that there is no risk of any leakage or fumes coming into contact with sparks or naked ﬂames, for example, from electrical machinery, electric motors, electrical relays/ switches or boilers.

• When storing and transporting fuel always use approved containers intended for this purpose.

• When storing the machine for long periods the fuel tank must be emptied. Contact your local gas station to ﬁnd out where to dispose of excess fuel.

• Ensure the machine is cleaned and that a complete service is carried out before long-term storage.

• The transport guard must always be ﬁtted to the cutting attachment when the machine is being transported or in storage.

• Secure the machine during transport.

WARNING! Take care when handling fuel. Bear in mind the risk of ﬁre, explosion

and inhaling fumes.

Fuel

CAUTION! The machine is equipped with a two-stroke

engine and must always been run using a mixture of gasoline and two-stroke engine oil. It is important to accurately measure the amount of oil to be mixed to ensure that the correct mixture is obtained. When mixing small amounts of fuel, even small inaccuracies can drastically affect the ratio of the mixture.

WARNING! Fuel and fuel fumes are highly inﬂammable and can cause

serious injury when inhaled or allowed to come in contact with the skin. For this reason observe caution when handling fuel and make sure there is adequate ventilation.

Gasoline

CAUTION! Always use a quality gasoline/oil mixture with

an octane rating of at least 87 octane ((RON+MON)/2). If your machine is equipped with a catalytic converter (see chapter on Technical data) always use a good quality unleaded gasoline/oil mixture. Leaded gasoline will destroy the catalytic converter.

Use low-emission gasoline, also known as alkylate gasoline, if it is available.

This engine is certiﬁed to operate on unleaded gasoline.

• The lowest recommended octane grade is 87 ((RON+MON)/2). If you run the engine on a lower octane grade than 87 so-called knocking can occur. This gives rise to a high engine temperature and increased bearing load, which can result in serious engine damage.

• When working at continuous high revs a higher octane rating is recommended.

Two-stroke oil

• For best results and performance use Universal, Universal powered by McCULLOCH two-stroke engine oil, which is specially formulated for our aircooled two stroke-engines.

• Never use two-stroke oil intended for water-cooled engines, sometimes referred to as outboard oil (rated TCW).

• Never use oil intended for four-stroke engines.

• Mixing ratio 1:50 (2%) with Universal, Universal powered by

McCULLOCH two-stroke oil.

FUEL HANDLING

Mixing

• Always mix the gasoline and oil in a clean container intended for fuel.

• Always start by ﬁlling half the amount of the gasoline to be used. Then add the entire amount of oil. Mix (shake) the fuel mixture. Add the remaining amount of gasoline.

• Mix (shake) the fuel mixture thoroughly before ﬁlling the machine’s fuel tank.

• Do not mix more than one month’s supply of fuel at a time.

• If the machine is not used for some time the fuel tank should be emptied and cleaned.

WARNING! The catalytic converter mufﬂer gets very hot during and after

use. This also applies during idling. Be aware of the ﬁre hazard, especially when working near ﬂammable substances and/ or vapours.

Fueling

WARNING! Taking the following precautions, will lessen the risk of ﬁre:

Do not smoke or place hot objects near fuel.

Always shut off the engine before refuelling.

Refuel in a well ventilated area. Never fuel the machine indoors.

Always stop the engine and let it cool for a few minutes before refuelling.

When refuelling, open the fuel cap slowly so that any excess pressure is released gently.

Tighten the fuel cap carefully after refuelling.

Always move the machine away from the refuelling area and source before starting.

• Clean the area around the fuel cap. Contamination in the tank can cause operating problems.

• Ensure that the fuel is well mixed by shaking the container before ﬁlling the tank.

MAINTENANCE

Carburetor

Adjustment of the idle speed

Before any adjustments are made, make sure that the air ﬁlter is clean and the air ﬁlter cover is ﬁtted. Make sure the start throttle position is disengaged.

Adjust the idle speed using the idle adjustment screw T, if it is necessary to readjust. First turn the T screw clockwise until the cutting attachment starts to move. Then turn the screw anticlockwise until the cutting attachment stops. The idle speed is correctly adjusted when the engine runs smoothly in every position. The idle speed should also be well below the speed at which the cutting attachment starts to move.

Rec. idle speed: See the Technical data section.

WARNING! If the idle speed cannot be adjusted so that the cutting attachment

stops, contact your dealer/service workshop. Do not use the machine until it has been correctly adjusted or repaired.

MAINTENANCE

Spark plug

The spark plug condition is inﬂuenced by:

• Incorrect carburetor adjustment.

• An incorrect fuel mixture (too much or incorrect type of oil).

• A dirty air ﬁlter.

These factors cause deposits on the spark plug electrodes, which may result in operating problems and starting difﬁculties.

If the machine is low on power, difﬁcult to start or runs poorly at idle speed: always check the spark plug ﬁrst before taking any further action. If the spark plug is dirty, clean it and check that the electrode gap is 0,5 mm (0,020"). The spark plug should be replaced after about a month in operation or earlier if necessary.

CAUTION! Always use the recommended spark plug type! Use of the wrong spark plug can damage the piston/ cylinder. Check that the spark plug is ﬁtted with a suppressor.

Air ﬁlter

Clean the ﬁlter every 25 hours, or more regularly if conditions are exceptionally dusty.

Cleaning the air ﬁlter

Remove the air ﬁlter cover and take out the ﬁlter. Wash it clean in warm, soapy water. Allow the ﬁlter to dry and then oil it in according to the instructions.

An air ﬁlter that has been in use for a long time cannot be cleaned completely. The ﬁlter must therefore be replaced with a new one at regular intervals.

must always be replaced.

A damaged air ﬁlter

Oiling the air ﬁlter

Always use ﬁlter oil, art. no. 531 00 92-48. The ﬁlter oil contains a solvent to make it spread evenly through the ﬁlter. You should therefore avoid skin contact.

Put the ﬁlter in a plastic bag and pour the ﬁlter oil over it. Knead the plastic bag to distribute the oil. Squeeze the excess oil out of the ﬁlter inside the plastic bag and pour off the excess before ﬁtting the ﬁlter to the machine. Never use common engine oil. This would drain through the ﬁlter quite quickly and collect in the bottom.

Make sure that the cooling system air intake is free of leaves and debris.

The air ﬁlter must be regularly cleaned to remove dust and dirt in order to avoid:

• Carburettor malfunctions

• Starting problems

• Loss of engine power

• Unnecessary wear to engine parts

• Excessive fuel consumption.

Gear

There is a plug for ﬁlling lubricant on the gear housing. Use the grease tube to ﬁll with grease and repeat every 25 hours. Use Husqvarna’s special grease.

CAUTION! The gear housing must not be ﬁlled completely with grease. The grease expands as the machine heats up during operation. If the gear housing was completely ﬁlled with grease it could damage the seals and lead to leakage of grease.

The grease in the bevel gear does not normally need to be changed except if repairs are carried out.

English – 17

MAINTENANCE

Cutting unit

Check that the cutting units' screws are ﬁtted correctly. Tighten them with a tightening torque of 7-10 Nm.

Cleaning and lubrication

Clean any resin and plant residue from the blades using cleaning agent 531 00 75-13 (UL22) before and after using the machine.

Check that the blade edges are not damaged or deformed. File away any burrs.

Check that the blades move freely. Remove the lubrication plug in the gear housing and stick in the combination spanner and turn back and forth.

Lubricate the blade bars with special grease, part no. 531 00 75-12 (UL 21) before long periods of storage.

IMPORTANT! Use only McCULLOCH replacement parts. Use of other

brands of replacement parts can cause damage to your unit or injury to the operator or others. Your warranty does not cover damage or liability caused by the use of accessories and/or attachments not speciﬁcally recommended by McCULLOCH.

FEDERAL AND CALIFORNIA EMISSIONS CONTROL WARRANTY STATEMENT

FEDERAL EMISSION CONTROL WARRANTY STATEMENT

IMPORTANT:

This product is compliant with U.S. EPA Phase 3 regulations for exhaust and evaporative emissions. To ensure EPA Phase 3 compliance, we recommend using only genuine McCULLOCH brand replacement parts. Use of non-compliant replacement parts is a violation of federal law.

YOUR WARRANTY RIGHTS AND OBLIGATIONS

The EPA (U.S. Environmental Protection Agency), CARB (California Air Resources Board), Environment Canada and McCULLOCH are pleased to explain the emissions control system’s warranty on your 2015-2016* small offroad engine. In U.S. and Canada, small off-road engines must be designed, built, and equipped to meet the applicable Federal or California stringent anti-smog standards. McCULLOCH must warrant the emissions control system on your small off-road engine for the period of time listed below provided there has been no abuse, neglect or improper maintenance of your small offroad engine. Your emission control system may include parts such as the carburetor, fuel-injection system, the ignition system, catalytic convertor, fuel tanks, fuel lines, fuel caps, valves, canisters, ﬁlters, vapor hoses, clamps, connectors, and other associated emission-related components.

For engines less than or equal to 80 cc, only the fuel tank is subject to the evaporative emission control warranty requirements of this section (California only). Where a warrantable condition exists, McCULLOCH will repair your small off-road engine at no cost to you including diagnosis, parts and labor.

MANUFACTURER′S WARRANTY COVERAGE

The emissions control system is warranted for two years. If any emissions-related part on your small off-road engine is defective, the part will be repaired or replaced by McCULLOCH.

OWNER′S WARRANTY RESPONSIBILITIES

• As the small off-road engine owner, you are responsible for performance of the required maintenance listed in your operator’s manual. McCULLOCH recommends that you retain all receipts covering maintenance on your small off-road engine, but McCULLOCH cannot deny warranty solely for the lack of receipts or your failure to ensure the performance of all scheduled maintenance.

• As the small off-road engine owner, you should however be aware that McCULLOCH may deny you warranty coverage if your small off-road engine or a part has failed due to abuse, neglect, or improper maintenance or unapproved modiﬁcations.

• You are responsible for presenting your small off-road engine to a McCULLOCH distribution center or service center as soon as the problem exists. The warranty repairs should be completed in a reasonable amount of time, not to exceed 30 days. If you have any questions regarding your warranty rights and responsibilities, you should contact your nearest authorized servicing dealer or call McCULLOCH in USA at 1-800-487-5951, in CANADA at 1-800-8055523 or send e-mail correspondence to emissions@husqvarnagroup.com

WARRANTY COMMENCEMENT DATE

The warranty period begins on the date the engine or equipment is delivered to an ultimate purchaser.

LENGTH OF COVERAGE

McCULLOCH warrants to the ultimate purchaser and each subsequent owner that the engine or equipment is designed, built, and equipped so as to conform with all applicable regulations adopted by EPA and CARB, and is free from defects in materials and workmanship that causes the failure of a warranted part for a period of two years.

WHAT IS COVERED

REPAIR OR REPLACEMENT OF PARTS Repair or

replacement of any warranted part under the warranty must be performed at no charge to the owner at a warranty station. Warranty services or repairs will be provided at all McCULLOCH distribution centers that are franchised to service the subject engines. Throughout the emissions warranty period of two years, McCULLOCH must maintain a supply of warranted parts sufﬁcient to meet the expected demand for such parts.

WARRANTY PERIOD Any warranted part that is scheduled for replacement as required in the maintenance schedule, is warranted for the period of time prior to the ﬁrst scheduled replacement point for that part. If the part fails prior to the ﬁrst scheduled replacement, the part will be repaired or replaced by McCULLOCH at no cost. Any such part repaired or replaced under warranty is warranted for the remainder of the period prior to the ﬁrst scheduled replacement point for the part. Any warranted part that is not scheduled for replacement as required in the maintenance schedule, is warranted for two years. If any such part fails during the period of warranty coverage, it will be repaired and replaced by McCULLOCH at no cost. Any such part repaired or replaced under the warranty is warranted for the remaining warranty period. Any warranted part that is scheduled only for regular inspection in the maintenance schedule will be warranted for a period of two years. A statement in such written instructions to the effect of ”repair or replace as necessary” will not reduce the period of warranty coverage. Any such part repaired or replaced under warranty will be warranted for the remaining warranty period.

DIAGNOSIS The owner must not be charged for diagnostic labor that leads to the determination that a
