QuickStop Super Chain Brake System

This STIHL chain saw is equipped with a chain brake system that can be activated in three different ways. As before, the chain brake can be activated by the inertia of the front hand guard in certain kickback situations or manually by pushing the front hand guard towards the bar nose. In both these cases the chain is brought to a standstill within a fraction of a second. In addition, there is a coasting brake function that stops chain rotation within a second of you letting go of the rear handle. The locked chain is not released again until you press down the throttle trigger interlock lever to operate the throttle.

The chain brake can be activated in three ways:

3 Manually by releasing the rear

handle

The activating mechanism of the QuickStop Super coasting brake is integrated in throttle trigger interlock (rear handle). One of the big advantages of this system is that the saw chain is automatically locked in position when carrying the running saw with the rear handle released.

Guide to Using this Manual

This Instruction Manual refers to a STIHL chain saw, also called a machine in this Instruction Manual.

Pictograms

Pictograms that appear on the machine are explained in this Instruction Manual.

Depending on the machine and equipment version, the following pictograms may appear on the machine.

WARNING

Warning where there is a risk of an accident or personal injury or serious damage to property.

NOTICE

Caution where there is a risk of damaging the machine or its individual components.

Engineering improvements

STIHL's philosophy is to continually improve all of its products. For this reason we may modify the design, engineering and appearance of our products periodically.

Therefore, some changes, modifications and improvements may not be covered in this manual.

Safety Precautions

Special safety precau tions must be observed to reduce the risk of per sonal injury when working with a chain saw because of the very high chain speed and very sharp cutters.

It is important that you read the instruction man ual before first use and keep it in a safe place for future reference. Nonobservance of the instruction manual may result in serious or even fatal injury.

General

Observe all applicable local safety regulations, standards and ordinances.

The use of noise emitting power tools may be restricted to certain times by national or local regulations.

If you have not used this model before: Have your dealer or other experienced user show you how to operate your machine or attend a special course in its operation.

Minors should never be allowed to use a chain saw.

Keep bystanders, especially children, and animals away from the work area.

The user is responsible for avoiding injury to third parties or damage to their property.

MS 362 C-MQ

001BA115 KN

Do not lend or rent your chain saw without the instruction manual. Be sure that anyone using it understands the information contained in this manual.

To operate a chain saw you must be rested, in good physical condition and mental health. If you have any condition that might be aggravated by strenuous work, check with your doctor before operating a chain saw.

Do not operate the chain saw if you are under the influence of any substance (drugs, alcohol) which might impair vision, dexterity or judgment.

To reduce the risk of accidents or injury, put off the work in poor weather conditions (rain, snow, ice, wind).

Persons with pacemakers only: The ignition system of your chainsaw produces an electromagnetic field of a very low intensity. This field may interfere with some pacemakers. To reduce health risks, STIHL recommends that persons with pacemakers consult their physician and the pacemaker manufacturer before operating this power tool.

Intended use

The machine may only be used to saw wood and wooden objects.

Do not the machine for any other purpose – risk of accidents!

Do not modify the machine in any way – this may increase the risk of personal injury. STIHL excludes all liability for personal injury and damage to property caused while using unauthorised attachments.

Clothing and Equipment

Wear proper protective clothing and equipment.

Clothing must be sturdy but allow complete free

dom of movement. Wear snug-fitting clothing with cut retardant inserts – do not wear a work coat.

Avoid clothing that could get caught on branches or brush or moving parts of the saw. Do not wear a scarf, necktie or jewelry. Tie up and confine long hair (e.g. with a hair net, cap, hard hat, etc.).

Wear steel-toed safety boots with cut retardant inserts and non-slip soles.

WARNING

To reduce the risk of eye injuries, wear snug-fitting safety glasses in accord ance with European Standard EN 166. Make sure the safety glasses are a good fit.

Wear a face shield and make sure it is a good fit. A face shield alone does not provide adequate eye protection.

Wear hearing protection, e.g. earplugs or ear muffs.

Wear a safety hard hat where there is a danger of head injuries from falling objects.

Wear heavy-duty work gloves made of durable material (e.g. leather).

STIHL offers a comprehensive range of personal protective clothing and equipment.

Transport

Before any transport – even over short distances – switch off the machine, engage the chain brake and attach the chain scabbard. This avoids the risk of the saw chain starting unintentionally.

Always carry the chain saw by the handle – with the hot muffler away from your body, the guide bar must point to the rear. Avoid touching hot parts of the machine, especially the surface of the muffler – risk of burns!

In vehicles: Properly secure the machine to prevent tipping, damage and chain oil or fuel spillage.

Cleaning

Clean plastic parts with a cloth. Harsh detergents can damage the plastic.

MS 362 C-MQ

English

Clean the dust and dirt off the machine – do not use any grease solvents for this purpose.

Clean the ventilation slots if necessary.

Do not use a high-pressure cleaner to clean the machine. The hard jet of water can damage parts of the machine.

Accessories

Only use those tools, guide bars, chains, chain sprockets, accessories or technically equivalent components that have been approved by STIHL for this machine. If you have any questions in this respect, consult a servicing dealer. Use only high quality tools and accessories. Otherwise, there may be a risk of accidents and damage to the machine.

STIHL recommends the use of genuine STIHL tools, guide bars, chains, chain sprockets and accessories. They are specifically designed to match your model and meet your performance requirements.

Refuelling

Petrol is an extremely flammable fuel – keep clear of naked flames and fire – do not spill any fuel – no smoking.

Switch off the engine before refuelling.

Never refuel the machine while the engine is still hot – the fuel may spill over – risk of fire!

Open the fuel filler cap carefully so that any excess pressure is relieved gradually and fuel does not splash out.

The machine may only be refuelled in a well ventilated place. Clean the machine immediately if fuel is spilled. Do not spill fuel over your clothing – contaminated clothing must be changed immediately.

The machines can be equipped with the following filler caps as standard:

Cliplock filler cap (bayonet-type)

Place the cliplock filler cap (bayonet-type) in position, turn as far as stop and fold the cliplock down.

This helps reduce the risk of unit vibrations causing an incorrectly tightened filler cap to loosen or come off and spill quantities of fuel.

Look out for leaks! Never start the engine if fuel has been spilled or is leaking – Fatal burns may result!

Before Starting Work

Check that your saw is properly assembled and in good condition – refer to appropriate chapters in the instruction manual.

– Check the fuel system for leaks,

paying special attention to visible parts such as the tank cap, hose connections and the manual fuel pump (on machines so equipped). If

there are any leaks or damage, do not start the engine – risk of fire. Have your saw repaired by a servicing dealer before using it again.

– Check operation of chain brake,

front hand guard

– Correctly mounted guide bar

– Correctly tensioned chain

– The trigger and trigger lockout must

move freely and spring back to the idle position when they are released.

– Master Control lever must move

easily to STOP, 0 or †

– Check that the spark plug boot is

secure – a loose boot may cause arcing that could ignite combustible fumes and cause a fire.

– Never attempt to modify the controls

or safety devices in any way.

– Keep the handles dry and clean –

free from oil and dirt – for safe control of the saw.

– Make sure there is sufficient fuel

and chain oil in the tanks.

To reduce the risk of personal injury, do not operate your saw if it is damaged or not properly assembled.

Starting the chain saw

Always work on a level surface. Ensure a firm and secure footing. Hold the machine securely – the chain must not touch any objects or the floor – danger of injury due to the rotating saw chain.

MS 362 C-MQ

English

001BA087 LÄ

Your chain saw is a one-person saw. Do not allow other persons to be in the working area – not even while starting.

Do not start the chain saw if the chain is in a cut.

Move at least 3 meters away from the place where the machine was refuelled and never start the motor in enclosed spaces.

Lock the chain with the chain brake before starting – risk of injury due to rotating chain!

Do not drop-start the engine – start as described in the Instruction Manual.

During operation

Ensure you always have a firm and safe footing. Take special care when the bark is wet – danger of slipping!

Always hold the chain saw firmly with both hands: Right hand on the rear handle – even if you are left-handed. To ensure reliable control, wrap your thumbs tightly around the handlebar and handle.

In the event of impending danger or in an emergency, switch off the engine immediately by moving the Master Control lever / stop switch to STOP, 0 or †.

Never let the machine run unattended.

Exercise caution with slippery surfaces, water, snow, ice, steep slopes, uneven ground or green wood that has just been stripped of its bark – danger of slipping!

Use caution with tree stumps, roots, ditches – danger of stumbling!

Do not work alone – keep within calling distance of others who are trained in emergency procedures and can provide help in an emergency. Helpers at the cutting site must also wear protective clothing (helmet!) and stand well clear of the branches being cut.

More care and attention than usual are required when wearing ear protection, as warning sounds (shouts, beeps, etc.) cannot be heard properly.

Take a break in good time to avoid tiredness or exhaustion – risk of accidents!

Dust (e. g., sawdust), fumes and smoke produced while using the machine may be hazardous to health. If dust is generated, wear a dust mask.

When the engine is running: Note that the saw chain continues to rotate for a short period after you let go of the throttle trigger – coasting effect.

No smoking when working with or near the chain saw - risk of fire! Combustible fuel vapour may escape from the fuel system.

Examine the saw chain periodically at short intervals and as soon as you note any tangible changes:

– Switch off the engine; wait until the

saw chain is stationary

– Check condition and secure fitting

– Check sharpness

Never touch the saw chain when the engine is running. If the saw chain becomes jammed by an object, switch off the engine immediately before attempting to remove the object – risk of injury!

Always turn off the engine before leaving the machine unattended.

To change the saw chain, switch off the engine. Risk of injury from the motor starting unintentionally!

Keep easily combustible materials (e. g., wood chips, bark, dry grass, fuel) away from hot exhaust gases and hot mufflers – risk of fire! Mufflers with catalytic converters can become especially hot.

Never work without chain lubrication – monitor the oil level in the oil tank. Stop work immediately if the oil level in the oil tank is too low and top up with chain oil – see also "Topping up with chain oil" and "Check chain lubrication".

If the machine 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 – see also "Before starting work".

Check the fuel system for leaks and make sure the safety devices are working properly. Never continue using

MS 362 C-MQ

English

a machine that is not in perfect working order. In case of doubt, have the unit checked by your servicing dealer.

Check for correct idling, so that the saw chain stops moving when the throttle trigger is released. Check the idle setting regularly and correct when possible. Have the machine repaired by a STIHL servicing dealer if the saw chain still continues to move during idling.

The chain saw produces poisonous exhaust gases as soon as the engine starts. These gases may be colourless and odour less and may contain unburnt hydrocarbons and benzene. Never work with the machine indoors or in poorly ventilated areas, even if your machine is equipped with a catalytic converter.

Ensure proper ventilation when working in trenches, hollows or other confined locations – risk of fatal injury from breathing toxic fumes!

If you feel sick, have a headache, vision problems (e. g., your field of vision gets smaller), hearing problems, dizziness or inability to concentrate, stop work immediately. Such symptoms may be caused by an excessively high concentration of exhaust emissions – risk of accident!

After finishing work

Switch off the motor, engage the chain brake and attach the chain scabbard.

Storage

When the machine is not in use, it should be stored in such a way that noone is endangered. Secure the machine against unauthorised use.

Store the machine in a safe, dry room.

Vibrations

Prolonged use of the power tool may result in vibration-induced circulation problems in the hands (whitefinger disease).

No general recommendation can be given for the length of usage because it depends on several factors.

The period of usage is prolonged by:

– Hand protection (wearing warm

gloves)

– Work breaks

The period of usage is shortened by:

– Any personal tendency to suffer

from poor circulation (symptoms: frequently cold fingers, tingling sensations).

– Low outside temperatures.

– The force with which the handles

are held (a tight grip restricts circulation).

Continual and regular users should monitor closely the condition of their hands and fingers. If any of the above symptoms appear (e.g. tingling sensation in fingers), seek medical advice.

Maintenance and repairs

Always switch off the engine before any repair, cleaning or maintenance work and any work on the chain. Risk of injury if the engine starts inadvertently!

The machine must be serviced regularly. Do not attempt any maintenance or repair work not described in the Instruction Manual. All other work should be carried out by a servicing dealer.

STIHL recommends that maintenance and repair work be carried out only by authorised STIHL dealers. STIHL dealers receive regular training and are supplied with technical information.

Use only high-quality spare parts. Otherwise, there may be a risk of accidents and damage to the machine. If you have any questions in this respect, consult a servicing dealer.

Do not modify the machine in any way – this may increase the risk of personal injury –risk of accidents!

To reduce the risk of fire due to ignition outside the cylinder, move the master control level to STOP, 0 or † before turning the engine over on the starter when the spark plug boot is removed or the spark plug is unscrewed!

Do not service or store the machine near a naked flame – risk of fire due to the fuel!

Check fuel cap regularly for tightness.

Use only spark plugs that are in perfect condition and have been approved by STIHL – see "Specifications".

Check ignition lead (insulation in good condition, secure connection).

MS 362 C-MQ

English

001BA036 KN

Check that the muffler is in perfect working condition.

Do not use the machine if the muffler is damaged or missing – risk of fire, damage to hearing!

Never touch a hot muffler – risk of burns!

The condition of the anti-vibration elements influences vibration behaviour – inspect anti-vibration elements periodically.

Inspect chain catcher – replace if damaged.

Switch off the engine

– To check the chain tension

– To retension the chain

– To replace the chain

– For remedying malfunctions

Observe sharpening instructions – for safe and proper handling, always keep the chain and guide bar in flawless condition. Keep the chain properly sharpened, tensioned and well lubricated.

Change chain, guide bar and chain sprocket in due time.

Regularly check that the clutch drum is in perfect working condition.

Always store fuel and chain lubricant only in the specified type of containers and ensure they are correctly labelled. Store in a dry, cool and secure place protected against light and sunlight.

In the event of a chain brake malfunction, switch off the machine immediately – risk of injury! Consult a

servicing dealer – do not use the machine until the malfunction has been remedied, see "Chain brake".

Reactive Forces

The most common reactive forces are: kickback, pushback and pull-in.

Dangers of kickback

Kickback can result in fatal cuts.

Kickback occurs when the saw is suddenly thrown up and back in an uncontrolled arc towards the operator.

MS 362 C-MQ

English

001BA257 KN

001BA037 KN

001BA038 KN

Kickback occurs if, for example,

– The saw chain in the area of the

upper quarter of the guide bar nose unintentionally comes into contact with wood or a solid object – e. g., unintentionally touches another limb during limbing

– The saw chain at the nose of the

guide bar is briefly pinched in the cut

QuickStop chain brake:

This device reduces the risk of injury in certain situations – it cannot prevent kickback. If activated, the brake stops the saw chain within a fraction of a second – refer to chapter "Chain brake" in this Instruction Manual.

Reducing the risk of kickback

– Work cautiously and methodically

– Hold the chain saw firmly with both

hands and maintain a secure grip

– Always cut at full throttle

– Be aware of the location of the guide

bar nose

– Do not cut with the guide bar nose

– Be especially careful with small,

tough limbs, undergrowth and offshoots – the saw chain may become caught in them

– Never cut several limbs at once

– Do not lean too far forward

– Do not cut above shoulder height

– Use extreme caution when re-

entering a previous cut

– Do not attempt plunge cuts if you

are not experienced in this cutting technique

– Be alert for shifting of the log or

other forces that may cause the cut to close and pinch the chain

– Always cut with a correctly

sharpened, properly tensioned saw chain – the depth gauge setting must not be too large

– Use low-kickback saw chains as

well as narrow-radius guide bars

Pull-in (A)

When the chain on the bottom of the bar – overbucking – is suddenly pinched, caught or encounters a foreign object in the wood, the chain saw may suddenly

be drawn forward toward the log – to avoid this, engage the bumper spike firmly in the wood.

Pushback (B)

When the chain on the top of the bar – underbucking – is suddenly pinched, caught or encounters a foreign object in the wood, the chain saw may suddenly be driven straight back toward the operator – to avoid this:

– Do not allow the top of the guide bar

to become jammed

– Do not twist the guide bar in the cut

Be very careful

– With freely hanging limbs

– With trunks that are under tension

between other trees because they fell unfavourably

– When working in windbreaks

In these cases, do not use a chain saw – use a hoist, winch or dragline instead.

Pull out trunks that are lying about and have been cut free. Whenever possible, deal with them in open areas.

MS 362 C-MQ

English

001BA082 KN

Dead wood (brittle, rotten or dead wood) poses a significant, highly unpredictable hazard. It is extremely difficult or even practically impossible to recognise the danger. Use aids such as winches or draglines.

When felling close to roads, rail lines, power lines, etc., work with particular care. If necessary, notify police, power companies or railway authorities.

Working Techniques

Sawing and felling work, including all related work (plunge cutting, limbing, etc.) may only be carried out by persons who have been specially trained and instructed. Persons who are not experienced chain saw users should not carry out any such work – increased risk of accidents!

Country-specific legislation on felling technique must be complied with during felling work.

Cutting

Do not operate your saw with the starting throttle lock engaged. Engine speed cannot be controlled with the throttle trigger in this position.

Work calmly and carefully – in daylight conditions and only when visibility is good. Ensure you do not endanger others – stay alert at all times.

First-time users are advised to practice cutting logs on a sawhorse – see "When cutting small logs".

Use the shortest possible guide bar: The chain, guide bar and chain sprocket must match each other and your saw.

Position the saw so that your body is clear of the cutting attachment.

Always pull the saw out of the cut with the chain running.

Use your chain saw for cutting only. It is not designed for prying or shoveling away limbs, roots or other objects.

Do not underbuck freely hanging limbs.

Take care when cutting scrub and young trees. The saw chain may catch and throw thin shoots in your direction.

To reduce the risk of injury, take special care when cutting shattered wood because of the risk of injury from slivers being caught and thrown in your direction.

Make sure your saw does not touch any foreign materials: Stones , nails , etc. m ay be flung off and damage the saw chain. The saw may kick back unexpectedly – risk of accidents.

If the rotating chain makes contact with a rock or other solid object there is a risk of sparking which may cause easily combustible material to catch fire under certain circumstances. Dry plants and scrub are also easily combustible, especially in hot and dry weather conditions. If there is a risk of fire, do not use your chainsaw near combustible

MS 362 C-MQ

English

001BA033 KN

001BA151 KN

001BA152 KN

materials, dry plants or scrub. Always contact your local forest authority for information on a possible fire risk.

If on a slope, stand on the uphill side of the log. Watch out for rolling logs.

When working at heights:

– Always use a lift bucket

– Never work on a ladder or in a tree

– Never work on an insecure support

– Do not work above shoulder height

– Never operate your power tool with

one hand

Begin cutting with the saw at full throttle and engage the spiked bumper firmly in the wood, and then continue cutting.

Never work without the spiked bumper because the saw may pull you forwards and off balance. Always engage the spiked bumper securely in the tree or limb.

Note when reaching the end of a cut that the saw is no longer supported in the kerf. You have to take the full weight of the machine since it might otherwise go out of control.

When cutting small logs:

– Use a sturdy and stable support –

sawhorse.

– Never hold the log with your leg or

foot.

– Never allow another person to hold

the log or help in any other way.

Limbing:

– Use a low kickback chain.

– Work with the saw supported

wherever possible.

– Do not stand on the log while

limbing it.

– Do not cut with the bar nose.

– Watch for limbs which are under

tension.

– Never cut several limbs at once.

Lying or standing logs under tension:

Always make cuts in the correct sequence (first at the compression side (1), then at the tension side (2), the saw may otherwise pinch or kick back – risk of injury.

N Make relieving cut at the

compression side (1)

N Make bucking cut at the tension

side (2)

Be wary of pushback when making bucking cut from the bottom upwards (underbuck).

NOTICE

Do not cut a lying log at a point where it is touching the ground because the saw chain will otherwise be damaged.

45°

Ripping cut:

Cutting technique in which the spiked bumper is not used – risk of pull-in – start the cut with the guide bar at the shallowest possible angle – take extra care since there is an increased danger of kickback.

Preparations for Felling

Check that there are no other persons in the felling area – other than helpers.

Make sure no-one is endangered by the falling tree – the noise of your engine may drown any warning calls.

Maintain a distance of at least 2 1/2 tree lengths from the next felling site.

Determine direction of fall and escape path.

Select gap in stand into which you want the tree to fall.

Pay special attention to the following points:

– The natural lean of the tree

– Any unusually heavy limb structure,

damage

– The wind direction and speed – do

not fell in high winds

– Sloping ground

– Neighboring trees

– Snow load

– Soundness of tree – take special

care if trunk is damaged or in case of deadwood (dry, decayed or rotted wood)

A Direction of fall B Escape path (or retreat path)

– Establish paths of escape for

everyone concerned – opposite to direction of fall at about 45°.

– Remove all obstacles from escape

paths.

– Place all tools and equipment a safe

distance away from the tree, but not on the escape paths.

– Always keep to the side of the falling

tree and only walk away along the preplanned escape path.

– On steep slopes, plan escape

routes parallel to the slope.

– When walking away along the

escape path, watch out for falling limbs and watch the top of the tree.

MS 362 C-MQ

English

001BA146 KN

001BA271 KN

001BA153 KN

Preparing work area at base of tree

– First clear the tree base and work

area from interfering limbs and brush to provide a secure footing.

– Clean lower portion of tree base

(e.g. with an axe) – sand, stones and other foreign objects will dull the saw chain.

– Make the vertical cut first, then the

horizontal – but only if the wood is sound

Felling Notch

Preparing felling notch

The felling notch (C) determines the direction of fall.

Important:

– Make felling notch at a right angle to

the planned direction of fall.

– Cut close to the ground.

– Cut to a depth of about 1/5 to 1/3 of

the trunk diameter.

Determine direction of fall with gunning sight on shroud and fan housing

Your chainsaw has a gunning sight on the shroud and fan housing. Use this gunning sight.

Making Felling Notch

Posit ion t he sa w so that the f elli ng no tch is at a right angle to the direction you want the tree to fall.

The sequence in which the felling notch is made with a horizontal cut (bottom) and angled cut (top) is defined in country-specific regulations.

N Make horizontal cut (bottom) N Make the angled cut (top) at about

45°- 60° to the horizontal cut.

001BA269 KN

Check direction of fall

N Position the saw in the horizontal

cut. The gunning sight must point in the planned direction of fall – if necessary, correct direction of fall by re-cutting the felling notch.

Sapwood cuts

felling notch to a depth of about 1/10 of trunk diameter. On large diameter trees, cut to no more than width of guide bar.

Do not make sapwood cuts if wood is diseased.

Basic Information on Felling Cut

Stump dimensions

The tree is felled with the felling cut (E).

– Cut horizontally.

– 1/10 (at least 3 cm) of width of

hinge (D) higher than bottom of felling notch (C).

The holding strap (F) or stabilizing strap (G) supports the tree and helps prevent it from falling prematurely.

– Width of strap: about 1/10 to 1/5 of

tree diameter.

– Do not cut into the strap while

making the felling cut.

– Leave a broader strap on rotten

trees.

Plunge cutting

– For relieving cuts during bucking

– For wood carving

Sapwood cuts in long-fibered softwood help prevent sapwood splintering when the tree falls. Make cuts at both sides of the trunk at same height as bottom of

The felling notch (C) determines the direction of fall.

The hinge (D) helps control the falling tree.

– Width of hinge: about 1/10 of tree

diameter.

– To reduce the risk of accidents, do

not cut through the hinge – you could lose control of the direction of fall.

– Leave a broader hinge on rotten

trees.

N Use a low kickback chain and

exercise particular caution

MS 362 C-MQ

English

001BA270 KN

001BA260 KN

001BA261 KN

1. Begin cut by applying the lower portion of the guide bar nose – do not use upper portion because of – risk of kickback. Start cutting at full throttle until depth of kerf is twice the width of the guide bar.

2. Swing saw slowly into plungecutting position – take care because of the risk of kickback or pushback.

3. Make the plunge cut very carefully. Danger of pushback.

Use the plunge-cutting sight if possible. The plunge-cutting sight and the top and bottom of the guide bar are parallel.

When making the plunge cut, the sight helps keep the hinge horizontal, i.e. the same thickness all round. To do this, hold the plunge-cutting sight parallel to the chord of the felling notch.

Felling wedges

Make use of wedges as soon as possible, i.e. providing they do not interfere with cutting. Drive wedge into felling cut with a suitable tool.

Use only aluminum or plastic wedges – never steel. Steel wedges can seriously damage the saw chain and cause dangerous kickback.

Select felling wedges that suit the diameter of the tree and width of the kerf (felling cut (E)).

Contact your STIHL dealer for advice on selecting the right felling wedge (length, width and height).

Choosing Right Felling Cut

The criteria for choosing the right felling cut are the same as those for determining the direction of fall and the escape path.

There are many different variations of these characteristics. Only the two most common characteristics are described in this manual:

Left: Normal tree – vertical trunk

with uniform tree crown.

Right: Leaner – tree crown leans in

direction of fall.

Felling Cut with Stabilizing Strap (Normal Tree)

A) Small diameter trees

Perform this felling cut when the tree diameter is smaller than the length of the guide bar.

Shout a warning before starting the felling cut.

N Start felling cut (E) using plunge-cut

method – insert full length of guide bar in the trunk.

N Engage the spiked bumper behind

the hinge and use it as a pivot – avoid repositioning the saw more than necessary.

N Enlarge felling cut as far as

hinge (1).

– Do not cut into the hinge. N Enlarge felling cut as far as

stabilizing strap (2).

– Do not cut into the stabilizing strap.

Chain Scabbard

Your saw comes standard with a chain scabbard that matches the cutting attachment.

If guide bars of different lengths are mounted to the saw, always use a chain scabbard of the correct length which covers the complete guide bar.

The length of the matching guide bars is marked on the side of the chain scabbard.

Guide bars longer than 90 cm require one scabbard extension. Guide bars longer than 120 cm require two scabbard extensions.

Depending on the model, the scabbard extension either comes standard with the saw or is available as a special accessory.

Fuel

Your engine requires a mixture of gasoline and engine oil.

WARNING

For health reasons, avoid direct skin contact with gasoline and avoid inhaling gasoline vapor.

STIHL MotoMix

STIHL recommends the use of STIHL MotoMix. This ready-to-use fuel mix contains no benzol or lead, has a high octane rating and ensures that you always use the right mix ratio.

STIHL MotoMix uses STIHL HP Ultra two-stroke engine oil for an extra long engine life.

MotoMix is not available in all markets.

Mixing Fuel

NOTICE

Unsuitable fuels or lubricants or mix ratios other than those specified may result in serious damage to the engine. Poor quality gasoline or engine oil may damage the engine, sealing rings, hoses and the fuel tank.

If your machine is equipped with a catalytic converter, you must use unleaded gasoline.

NOTICE

A few tankfuls of leaded gasoline will greatly reduce the efficiency of the catalytic converter.

Gasoline with an ethanol content of more than 10% can cause running problems in engines with a manually adjustable carburetor and should not be used in such engines.

Engines equipped with M-Tronic deliver full power when run on gasoline with an ethanol content of up to 25% (E25).

Engine oil

Use only high-quality two-stroke engine oil – preferably STIHL HP, HP Super or HP Ultra, which are specially formulated for use in STIHL engines. HP Ultra guarantees high performance and a long engine life.

These engine oils are not available in all markets.

Use only STIHL 50:1 two-stroke engine oil for the fuel mix in models with a catalytic converter.

Mix Ratio

STIHL 50:1 two-stroke engine oil: 50 parts gasoline to 1 part oil

MS 362 C-MQ

Gasoline

Use only high-quality brand-name gasoline with a minimum octane rating of 90 – leaded or unleaded.

Chain Lubricant Filling Chain Oil Tank

For automatic and reliable lubrication of the chain and guide bar – use only an environmentally compatible quality chain and bar lubricant. Rapidly biodegradable STIHL BioPlus is recommended.

NOTICE

Biological chain oil must be resistant to

aging (e.g. STIHL BioPlus), since it will otherwise quickly turn to resin. This results in hard deposits that are difficult to remove, especially in the area of the chain drive and chain. It may even cause the oil pump to seize.

The service life of the chain and guide bar depends on the quality of the lubricant. It is therefore essential to use only a specially formulated chain lubricant.

WARNING

Do not use waste oil. Renewed contact with waste oil can cause skin cancer. Moreover, waste oil is environmentally harmful.

NOTICE

Waste oil does not have the necessary lubricating properties and is unsuitable for chain lubrication.

Preparations

N Thoroughly clean the oil filler cap

and the area around it to ensure that no dirt falls into the tank.

N Position the machine so that the

filler cap is facing up.

N Open the filler cap.

Fill up with chain oil.

N Refill the chain oil tank every time

you refuel.

Take care not to spill chain oil while refilling and do not overfill the tank.

STIHL recommends you use the STIHL filler nozzle for chain oil (special accessory).

N Close the filler cap.

There must still be a small amount of oil in the oil tank when the fuel tank is empty.

MS 362 C-MQ

English

143BA024 KN

If the oil level in the tank does not go down, the reason may be a fault in the oil supply system: Check chain lubrication, clean the oilways, contact your dealer for assistance if necessary STIHL recommends that you have servicing and repair work carried out exclusively by an authorized STIHL servicing dealer.

Checking Chain Lubrication

The saw chain must always throw off a small amount of oil.

NOTICE

Never operate your saw without chain lubrication. If the chain runs dry, the whole cutting attachment will be irretrievably damaged within a very short time. Always check chain lubrication and the oil level in the tank before starting work.

Every new chain has to be broken in for about 2 to 3 minutes.

After breaking in the chain, check chain tension and adjust if necessary – see "Checking Chain Tension".

Chain Brake

The chain brake system has two functions:

N Standard STIHL chain brake N STIHL coasting brake

The coasting brake stops chain rotation as soon as you release the saw's rear handle.

Coasting brake is activated

N When you let go of the rear handle.

MS 362 C-MQ

English

Disengaging the coasting brake

N Press down the throttle trigger

interlock lever. This releases the clutch drum and allows the chain to rotate.

Chain brake is activated

Disengaging the chain brake

N Pull the hand guard back toward the

front handle.

NOTICE

Always disengage chain brake before accelerating the engine (except when checking its operation) and before starting cutting work.

High revs with the chain brake engaged (chain locked) will quickly damage the powerhead and chain drive (clutch, chain brake).

Chain brake is activated by inertia

Checking operation of the coasting brake

Before starting work: Open the throttle wide and then release the rear handle. The chain must stop moving within less than a second.

Checking operation of the chain brake

Before starting work: Run engine at idle speed, engage the chain brake (push hand guard towards bar nose) and open the throttle wide for no more than 3 seconds – the chain must not rotate. The hand guard must be free from dirt and move freely.

In case of doubt about the above functions, contact your servicing dealer for assistance. STIHL recommends that you have servicing and repair work carried out exclusively by an authorized STIHL servicing dealer.

Chain brake maintenance

N When the hand guard is pushed

towards the bar nose by the left hand or by inertia in certain kickback situations.

The chain is stopped and locked.

If the kickback force of the saw is high enough.

The hand guard is accelerated towards the bar nose – even if your left hand is not behind the hand guard, e.g. during the felling cut.

The chain brake will operate only if the front hand guard has not been modified in any way.

The chain brake is subject to normal wear. It is necessary to have it serviced and maintained regularly by trained personnel. STIHL recommends that you have servicing and repair work carried out exclusively by an authorized STIHL servicing dealer. Maintain the following servicing intervals:

Full-time usage: every 3

months

Part-time usage: every 6

Operating Instructions

During the 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 unnecessarily 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 shortblock are greater during this period. The engine develops its maximum power after about 5 to 15 tank fillings.

During work

NOTICE

Open the throttle only when the chain brake is off. Running the engine at high revs with the chain brake engaged (chain locked) will quickly damage the engine and chain drive (clutch, chain brake).

Check chain tension frequently

A new saw chain must be retensioned more frequently than one that has been in use already for an extended period.

Chain cold

Tension is correct when the chain fits snugly against the underside of the bar but can still be pulled along the bar by hand. Retension if necessary – see "Tensioning the Saw Chain".

Chain at operating temperature

The chain stretches and begins to sag. The drive links must not come out of the bar groove on the underside of the bar – the chain may otherwise jump off the bar. Retension the chain – see "Tensioning the Saw Chain".

NOTICE

The chain contracts as it cools down. If it is not slackened off, it can damage the crankshaft and bearings.

After a long period of full-throttle operation

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

After finishing work

N Slacken off the chain if you have

retensioned it at operating temperature during work.

NOTICE

Always slacken off the chain again after finishing work. The chain contracts as it cools down. If it is not slackened off, it can damage the crankshaft and bearings.

Short-term storage

Wait for engine to cool down. Keep the machine with a full tank of fuel in a dry place, well away from sources of ignition, until you need it again.

Long-term storage

Basic information

M-Tronic regulates the fuel quantity and ignition timing for all operating states electronically.

M-Tronic stands for easy, fast starting, constant optimum engine performance, outstanding acceleration and automatic adaptation to changes in operating conditions.

Manual carburetor adjustments are no longer required – the carburetor does not have any adjusting screws.

Automatic adjustment

Under extremely changed operating conditions, attainment of the optimal setting can be accelerated as follows:

N Carry out five uniform cuts to length

under full load

N If the engine is down on power,

difficult to start or runs poorly at idle speed, first check the spark plug.

N Fit a new spark plug after about 100

operating hours – or sooner if the electrodes are badly eroded. Install only suppressed spark plugs of the type approved by STIHL – see "Specifications".

Maintaining and Sharpening the Saw Chain

Sawing effortlessly with a properly sharpened saw chain

A properly sharpened saw chain cuts through wood effortlessly even with very little pushing.

Never use a dull or damaged saw chain – this leads to increased physical strain, increased vibration load, unsatisfactory cutting results and increased wear.

N Clean the saw chain N Check the saw chain for cracks and

damaged rivets

N Replace damaged or worn chain

components and adapt these parts to the remaining parts in terms of shape and level of wear – rework accordingly

Carbide-tipped (Duro) saw chains are especially wear-resistant. For an optimal sharpening result, STIHL recommends STIHL servicing dealers.

WARNING

Compliance with the angles and dimensions listed below is absolutely necessary. An improperly sharpened saw chain – especially depth gauges that are too low – can lead to increased kickback tendency of the chain saw – risk of injury!

Chain pitch

The chain pitch marking (a) is embossed in the area of the depth gauge of each cutter.

Marking (a)Chain pitch

Inches mm 7 1/4 P 6.35 1 or 1/4 1/4 6.35 6, P or PM 3/8 P 9.32 2 or 325 0.325 8.25 3 or 3/8 3/8 9.32 4 or 404 0.404 10.26

The diameter of file to be used depends on the chain pitch – see table "Sharpening tools".

The angles of the cutter must be maintained during resharpening.

Sharpening and side plate angles

A Sharpening angle

STIHL saw chains are sharpened with a 30° sharpening angle. Ripping chains, which are sharpened with a 10° sharpening angle, are exceptions. Ripping chains have an X in the designation.

B Side plate angle

The correct side plate angle results automatically when the specified file holder and file diameter are used.

Tooth shapes Angle (°)

Micro = semi-chisel tooth, e. g., 63 PM3, 26 RM3, 36 RM

Super = full chisel tooth, e. g., 63 PS3, 26 RS, 36 RS3

Ripping chain, e. g., 63 PMX, 36 RMX

The angles must be identical for all cutters in the saw chain. Varying angles: Rough, uneven running of the saw chain, increased wear – even to the point of saw chain breakage.

File holder

N Use a file holder

Always use a file holder (special accessory, see table "Sharpening tools") when sharpening saw chains by hand. File holders have markings for the sharpening angle.

Use only special saw chain files! Other files are unsuitable in terms of shape and type of cutting.

To check the angles

Proper sharpening

N Select sharpening tools in

accordance with chain pitch

N Clamp guide bar if necessary N Block saw chain – push the hand

guard forward

N To advance the saw chain, pull the

hand guard toward the handlebar: The chain brake is disengaged. With the Quickstop Super chain brake system, additionally press the throttle trigger lockout

N Sharpen frequently, removing little

ma ter ial – two or thr ee strok es o f the file are usually sufficient for simple resharpening

markings on the file holder – rest the file holder on the tooth head and the depth gauge

N File only from the inside outward N The file only sharpens on the

forward stroke – lift the file on the backstroke

N Do not file tie straps and drive links N Rotate the file a little periodically in

order to avoid uneven wear

N To remove file burr, use a piece of

hardwood

N Check angle with file gauge

All cutters must be equally long.

With varying cutter lengths, the cutter heights also vary and cause rough running of the saw chain and chain breakage.

N All cutters must be filed down equal

to the length of the shortest cutter – ideally, one should have this done by a servicing dealer using an electric sharpener

STIHL filing gauge (special accessory, see table "Sharpening tools") – a universal tool for checking sharpening and side plate angles, depth gauge setting, and tooth length, as well as cleaning grooves and oil inlet holes.

N Guide the file: horizontally (at a ri ght

angle to the side surface of the guide bar) in accordance with the specified angle – according to the

Depth gauge setting

The depth gauge determines the depth to which the cutter penetrates the wood and thus the chip thickness.

Lowering the depth gauges

The depth gauge setting is lowered when the cutter is sharpened.

N Check the depth gauge setting after

each sharpening

Saw chains with humped drive link (2) – upper part of the humped drive link (2) (with service mark) is lowered at the same time as the depth gauge of the cutter.

WARNING

The rest of the humped drive link must not be filed; otherwise, this could increase the tendency of the chain saw to kick back.

N Rework t he de pth gauge so t hat i t is

flush with the file gauge

WARNING

Depth gauges that are too low increase the kickback tendency of the chain saw.

N Lay the file gauge on the saw chain

– the highest point of the depth gauge must be flush with the file gauge

N After sharpening, clean the saw

chain thoroughly, removing any filings or grinding dust – lubricate the saw chain thoroughly

N In the event of extended periods of

disuse, store saw chains in cleaned and oiled condition

N Lay the appropriate file gauge (1)

for the chain pitch on the saw chain and press it against the cutter to be checked – if the depth gauge protrudes past the file gauge, the depth gauge must be reworked

MS 362 C-MQ

N Afterwards, dress the leading edge

of the depth gauge parallel to the service mark (see arrow) – when doing this, be careful not to further lower the highest point of the depth gauge
