2 Safety Precautions English

Therefore, some changes, modifications and improvements may not be covered in this man‐ ual.

2 Safety Precautions

Special safety precautions 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 manual before first use and keep it in a safe place for future reference. Non-observance of the instruction manual may result in seri‐ ous or even fatal injury.

2.1 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 unit or attend a special course in its operation.

Minors should never be allowed to use a chain saw.

Keep bystanders, especially children, and ani‐ mals away from the work area.

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

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.

Persons who are not able to operate the power tool safely due to limited physical, sensory or mental ability may work with it only under super‐ vision or after instruction by a responsible per‐ son.

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).

2.2 Intended Use

The chainsaw may be used for cutting wood and wooden objects only. It is particularly suitable for cutting firewood and other woodworking projects close to the house.

It must not be used for any other purpose because of the increased risk of accidents.

Never attempt to modify your saw in any way since this may increase the risk of personal injury. STIHL excludes all liability for personal injury and damage to property caused while using unauthorized attachments.

2.3 Clothing and Equipment

Wear proper protective clothing and equipment.

Clothing must be sturdy but allow complete freedom 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 suitable footwear with cut retardant inserts, non-slip soles and steel toe.

WARNING

To reduce the risk of eye injuries, wear close-fitting safety glasses in accordance with European Standard EN 166. Make sure the safety glasses are a comfortable and snug fit.

Wear a face shield and make sure it is a good fit.

Hearing protection is recommended if your daily working time is more than 2.5 hours.

Wear a safety hard hat with chin strap 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.

2.4 Transporting

Always switch off the chainsaw before carrying it – even for short distances, disconnect the plug from the wall outlet, move the hand guard to ƒ and fit the chain scabbard. This avoids the risk of the motor starting unintentionally.

Carry your chainsaw by the front handle only with the guide bar behind you.

In vehicles: Properly secure your chainsaw to prevent turnover, chain oil spillage and damage.

2.5 Cleaning

Clean plastic surfaces with a cloth. Do not use aggressive detergents. They may damage the plastic.

Always clean dust and dirt off the chainsaw – do not use any grease solvents for this purpose.

Clean the cooling slots if necessary.

Do not use a pressure washer to clean the saw. The solid jet of water may damage parts of the saw.

Do not spray the chainsaw with water.

2.6 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.

2.7 Drive Gear

2.7.1 Electrical Connection.

The wall outlet must be equipped with a groundfault circuit breaker or such a device must be installed between the wall outlet and the power tool – see "Connecting Saw to Power Supply".

If the connecting cord is damaged, immediately disconnect the plug from the power supply to avoid the risk of electric shock.

Reduce the risk of electric shock:

–

rating plate) and the voltage and frequency of your power supply must be the same. Check the connecting cord, plug, extension

–

cord and safety devices for damage. Never use damaged cords, couplings and plugs or connecting cords that do not comply with regu‐ lations. Always connect the power tool to a properly

–

installed wall outlet. Check that the insulation of the power cord,

–

extension cord, plug and coupling is in good condition. Never jerk the connecting cord to disconnect it

–

from the wall outlet. To unplug, grasp the plug, not the cord.

Position the connecting and extension cords cor‐ rectly:

Check minimum cross section of wires (wire

–

gauge) – see "Connecting to Power Supply". To reduce the risk of stumbling, position and

–

mark the connecting cord so that it cannot be damaged or endanger others. Using unsuitable extension cords can be dan‐

–

gerous. Make sure the extension cord used complies with the regulations for the intended application. The plug and coupling of the extension cord

–

must be water-proof and must never be immersed in water. Do not chafe on edges, pointed or sharp

–

objects Do not squeeze through gaps in doors or win‐

–

dows If cords are twisted – unplug the power tool

–

and straighten them out Always unwind the extension cord completely

–

from the cable drum to reduce the risk of fire from overheating. The extension cord must always be behind

–

you (i.e. the operator). Make sure that it cannot become entangled

–

with branches during cutting. Position the connecting cord so that it cannot

–

come into contact with the rotating chain.

Do not drive over, squash or jerk the connecting cord. Protect it from heat, oil and sharp edges.

–

Correctly tensioned chain

–

The trigger and trigger lockout must move

–

freely and spring back to the idle position when they are released. Trigger is locked in position when trigger lock‐

–

out is not depressed. 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 chain oil in the

–

tank.

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

2.9 Switching On the Saw

Start the saw on level ground only. Make sure you have a firm footing. Hold the saw firmly – check that the cutting attachment is not touching any object or the ground.

The chainsaw is a one-person saw. Do not allow other persons in the work area – even when starting.

Do not attempt to switch on the saw when the saw chain is in a cut.

Switch on as described in the instruction manual.

2.10 During Operation

Make sure you always have good balance and secure footing. To avoid slipping, take special care when the bark is wet.

Always hold your saw firmly with both hands: Right hand on the rear handle, even if you are left-handed. To ensure safe control, wrap your fingers tightly around the front handle and control handle.

In case of imminent danger or in an emergency, switch off the chainsaw immediately, move hand guard to ƒ and disconnect the plug from the wall outlet.

The drive motor is not waterproof. Never work with the power tool in the rain or in wet or very damp locations.

Do not leave you power tool out in the rain and do not operate it as long as it is damp.

Take special care in slippery conditions – damp, snow, ice, on slopes, uneven ground and freshly debarked logs.

Watch out for obstacles such as tree stumps, roots and ditches which could cause you to trip or stumble.

Do not work alone – keep within calling distance of other persons trained in first aid who can pro‐ vide assistance in an emergency. Helpers at the cutting site must also wear protective clothing (hard hat) and stand well clear of the branches being cut.

Be particularly alert and cautious when wearing hearing protection because your ability to hear warnings (shouts, alarms, etc.) is restricted.

To reduce the risk of accidents, take a break in good time to avoid tiredness or exhaustion.

The dusts (e.g. sawdust), vapor and smoke pro‐ duced during operation may be dangerous to health. If dust levels are very high, wear a suita‐ ble respirator.

Check the saw chain at regular short intervals during operation or immediately if there is a noticeable change in cutting behavior:

0458-756-0121-B 5

English

Switch off the motor, wait for the chain to

–

come to a standstill, disconnect the plug from the wall outlet. Check condition and proper mounting.

–

Check sharpness.

–

Do not touch the chain while the chainsaw is switched on. If the chain becomes jammed by an obstacle, switch off the motor immediately and disconnect the plug from the power supply before attempting to free the obstruction – risk of injury.

Before leaving your saw, switch it off, move the hand guard to ƒ and disconnect the plug from the wall outlet to reduce the risk of the motor starting unintentionally.

To replace the saw chain, switch off the chain‐ saw, move hand guard to ƒ and disconnect the plug from the wall outlet. This avoids the risk of injury from the motor starting unintentionally.

Your power tool is equipped with a system designed to quickly stop the saw chain – it comes to an immediate standstill as soon as you release the trigger switch – see "Coasting Brake".

Check this function at regular short intervals. Do not operate your chainsaw if the chain continues to run after you release the trigger switch – see "Coasting Brake" – risk of injury. Contact your servicing dealer.

Never operate your saw without proper chain lubrication – check oil level regularly during oper‐ ation. Stop work immediately if the oil level is too low and refill the oil tank – see also chapters on "Filling Chain Oil Tank" and "Checking Chain Lubrication".

If your saw 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 Start‐ ing Work". Make sure the safety devices are working properly. Do not continue operating your saw if it is damaged. In case of doubt, consult your servicing dealer.

2.11 After Finishing Work

Switch off the saw, move the hand guard to ƒ, disconnect the plug from the wall outlet and fit the chain scabbard.

2 Safety Precautions

2.12 Storing

When the chainsaw is not in use, store it so that it does not endanger others. Secure it against unauthorized use.

Store your chainsaw in a dry location with the hand guard on ƒ and the plug disconnected from the wall outlet.

2.13 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 cir‐

–

culation (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.

2.14 Maintenance and Repairs

Before carrying out any repairs, cleaning or maintenance work or work on the cutting attach‐ ment, always switch off the chainsaw, move the hand guard to ƒ and disconnect the plug from the wall outlet. This avoids the risk of injury from the chain starting unintentionally.

Service the chainsaw regularly. Do not attempt any maintenance or repair work not described in the instruction manual. Have all other work per‐ formed by a servicing dealer.

STIHL recommends that you have servicing and repair work carried out exclusively by an author‐ ized STIHL servicing dealer. STIHL dealers are regularly given the opportunity to attend training courses and are supplied with the necessary technical information.

Only use high-quality replacement parts in order to avoid the risk of accidents and damage to the saw. If you have any questions in this respect, consult a servicing dealer.

3 Reactive Forces English

Never attempt to modify your saw in any way since this may increase the risk of personal injury.

Regularly check the electrical contacts and ensure that the insulation of the connecting cord and plug shows no sign of aging (brittleness).

Electrical components, e.g. power cord, may only be repaired or replaced by a qualified electrician.

Check the chain catcher and replace it if dam‐ aged.

Observe sharpening instructions – keep the chain and guide bar in good condition at all times for safe and correct handling of the machine. The chain must be properly sharpened, tensioned and well lubricated.

Always change the chain, guide bar and sprocket in good time.

Store chain lubricant in properly labeled, safetytype canisters only. Store in a dry, cool and safe location protected from light and the sun.

If there is a problem with the chain brake, switch off the saw immediately, move the hand guard to ƒ and disconnect the plug from the wall outlet – risk of injury. Contact your servicing dealer – do not use your saw until the problem has been rec‐ tified (see "Chain Brake").

3 Reactive Forces

The most common reactive forces that occur dur‐ ing cutting are: kickback, pushback and pull-in.

3.1 Dangers of kickback

Kickback can result in serious or fatal injury.

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

3.2 Kickback occurs if, e. g.,

when the upper quadrant of the bar nose unin‐

–

tentionally contacts wood or another solid object, e.g. when another limb is touched acci‐ dentally during limbing. when the chain at the nose of the guide bar is

–

pinched in the cut.

3.3 Quickstop chain brake:

This device reduces the risk of injury in certain situations – it cannot prevent kickback. When activated, the chain brake stops the saw chain within a fraction of a second – see the section "Saw chain" in this Instruction Manual.

3.4 To reduce the risk of kickback

Work cautiously and avoid situations which

–

could cause kickback. Hold the saw firmly with both hands and main‐

–

tain a secure grip. always cut at full throttle.

–

Be aware of the location of the guide bar nose

–

at all times. do not cut with the bar nose.

–

Take special care with small, tough limbs, they

–

may catch the chain. never cut several limbs at once.

–

do not overreach.

–

never cut above shoulder height.

–

Use extreme caution when re-entering a previ‐

–

ous cut. Do not attempt plunge cuts if you are not

–

experience 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, prop‐

–

erly tensioned chain – the depth gauge setting must not be too large. Use a low kickback chain and a narrow radius

–

guide bar.

3.5 Pull-in (A)

complicated, if not impossible. Use aids such as a cable winch or tractor in such cases.

When felling in the vicinity of roads, railways, power lines, etc., take extra precautions. If nec‐ essary, inform the police, utility company or rail‐ way authority.

4 Working Techniques

Only specially trained persons may perform cut‐ ting and felling operations and all other associ‐ ated work (plunge cutting, limbing, etc.). To

Pull-in occurs when the chain on the bottom of the bar is suddenly pinched, caught or encoun‐ ters a foreign object in the wood. The reaction of the chain pulls the saw forward – to reduce this risk, always engage the spiked bumper securely in the tree or limb.

3.6 Pushback (B)

Pushback occurs when the chain on the top of the bar is suddenly pinched, caught or encoun‐ ters a foreign object in the wood. The reaction of the chain drives the saw straight back toward the operator – to avoid this risk:

Be alert to situations that may cause the top of

–

the guide bar to be pinched Do not twist the guide bar in the cut

–

3.7 Exercise extreme caution

with leaners

–

with trees that have fallen unfavorably

–

between other trees and are under strain when working in blowdown areas.

–

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

Pull out exposed and cleared logs. Select clear area for cutting.

Deadwood (dry, decayed or rotted wood) repre‐ sents a considerable risk that is difficult to assess. Identifying the extent of the dangers is

8 0458-756-0121-B

reduce the risk of accidents and injury, do not attempt felling or limbing if you are not an experi‐ enced chainsaw user.

Gasoline chain saws are more suitable than electric saws for felling and limbing. The freedom of movement necessary for this work is restricted by the connecting cord.

Your electric chain saw is unsuitable for cutting in blowdown areas and must not be used for such work.

However, if a tree is to be felled and limbed with an electric saw against this recommendation, it is essential to observe country-specific regulations on felling techniques.

4.1 Sawing

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

It is advisable for first-time users to practice cut‐ ting logs on a sawbuck – see "Sawing thin wood".

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.

001BA152 KN

4 Working Techniques English

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.

Be careful when cutting scrub and young trees. Thin shoots can be scooped up by the chain saw and hurled towards the user.

Be careful when cutting splintered wood – Risk of injury from ejected pieces of wood!

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

If a rotating saw chain hits a stone or another hard object, sparks may be generated which may ignite easily flammable materials under certain conditions. Also dried-out plants and brushwood are combustible, above all in hot and dry weather. If there is a risk of fire, do not use the chain saw in the vicinity of easily combustible materials, dry plants or scrub. It is mandatory that you ask the responsible forestry office about the current fire hazard.

At the end of the cut, the chain saw is no longer supported by the cutting attachment in the cut. The chain saw's weight must be borne by the user – risk of loss of control!

Sawing thin wood:

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 possi‐

–

ble. 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 the cuts in the correct order (first compression side (1), then tension side (2)), oth‐ erwise the cutting attachment may stick in the cut or kick back – risk of injury!

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 use the machine while standing on a

–

ladder or in a tree Never work on an insecure support

–

Never work above shoulder height

–

Never use the machine with just 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 hold the spiked bumper securely against the tree or limb.

0458-756-0121-B 9

► Make relieving cut at the compression side (1) ► 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 touch‐ ing the ground because the saw chain will other‐ wise be damaged.

Ripping:

–

Neighboring trees

–

Snow load

–

Take the general condition of the tree into

–

account – be especially careful with trunk damage or deadwood (brittle, rotten or dead wood)

Sawing technique without use of the spiked bumper – risk of pull-in – position the guide bar at as shallow an angle as possible – be especially careful – increased risk of kickback!

4.2 Preparing for felling

Check that there are no other persons in the fell‐ ing 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.

Determining 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 inclination of the tree

–

Unusually heavy limb structure, asymmetrical

–

growth, damage to tree The wind direction and speed – do not fell in

–

high winds

A Direction of fall

B Escape path (escape routes)

Establish escape paths for each worker –

–

approx. 45° diagonally opposite to the direc‐ tion of fall Clear escape paths, eliminate obstacles

–

Put down tools and equipment at a safe dis‐

–

tance – but not on the escape paths When felling, stand only to the side of the fall‐

–

ing trunk and only move back laterally onto the escape path Plan escape paths on slopes parallel to the

–

slope When walking away along the escape path,

–

watch out for falling limbs and watch the top of the tree.

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. Carefully clear the base of the trunk (e.g., with

–

an axe) – sand, stones and other foreign objects will blunt the saw chain

4.3 Felling notch

Preparing the felling notch

When making a felling notch, align the chainsaw so that the notch lies at a right angle to the direc‐ tion of fall.

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

Important:

Make a felling notch at right angle to direction

–

of fall Saw as close to the ground as possible

–

Cut to a depth of approx. 1/5 to 1/3 of the

–

diameter of the trunk

Specify the direction of fall – without the gunning sight on the shroud and fan housing

If the chain saw is designed without the gunning sight on the shroud and fan housing, the direc‐ tion of fall can be determined or controlled using a meter stick:

During the procedure, various sequences are permitted for making a felling notch with a bottom (horizontal) cut and top (angled) cut – comply with national legislation regarding felling techni‐ que. ► Make the bottom cut (horizontal cut) – until the

guide bar reaches both markings

► Make the top (angled) cut approx. 45°‑ 60° to

the bottom cut

Checking the direction of fall

The bottom cut and top cut must meet in a con‐ tinuous straight sink chord.

► Position the meter stick at the pivot point of

the sink chord – the tip of the meter stick must point in the direction of the specified direction

► Snap the meter stick in the middle and create

an isosceles triangle

of fall – where necessary, correct the direction of fall by cutting the felling notch accordingly

► Position both ends of the meter stick in the

front trunk area (1/5 to max. 1/3 of the trunk diameter) – align the tip of the meter stick in the defined direction of fall

► Mark the trunk at both ends of the meter stick

to limit the felling notch

4.4 Sapwood cuts

Plunge cutting

For relieving cuts during shortening

–

For wood carving

–

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

4.5 Basic information on felling cut

Basic dimensions

► Use a low kickback saw chain and proceed

with special care

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

2. Swing the machine slowly into the plunge cutting position – risk of kickback and push‐ back!

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

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

The hinge (D) functions like a real hinge to guide the tree to the ground.

Width of hinge: approx. 1/10 of the trunk diam‐

–

eter Never saw through the hinge while felling –

–

otherwise the tree will fall in a direction other than the one planned – risk of accident! With rotten trunks, leave a wider hinge

–

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

Cut horizontally

–

1/10 (min. 3 cm) of the width of the hinge (D)

–

across the bottom of the felling notch (C)

The holding wood (F) or safety strip (G) supports the tree and secures it against premature falling.

Width of strip: approx. 1/10 to 1/5 of the trunk

–

diameter Do not cut into the strip during the felling cut

–

With rotten trunks, leave a wider strip

–

12 0458-756-0121-B

Where possible, use a plunge blade. The plunge blade and the upper/lower side of the guide bar are parallel.

During plunge cutting, the plunge bar helps to keep the hinge parallel in form, i.e. the same thickness at all points. To do this, guide the plunge bar parallel to the sink chord.

Felling wedges

Insert the felling wedge as soon as possible, i.e. as soon as no obstruction of saw control is to be expected. Position the felling wedge in the felling cut and drive in with suitable tools.

Only use aluminum or plastic wedges – do not use steel wedges. Steel wedges can seriously

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 formu‐ lated chain lubricant.

21 Operating Instructions English

► Depress the reset button (1) as far as stop – if

the motor does not run when you switch on, the overload cutout has not yet cooled down sufficiently – wait a while and then depress the reset button again as far as stop.

When the motor restarts: ► Run the motor off-load for about 15 seconds.

This cools the motor and helps prevent the overload cutout from tripping again.

20.2 MSE 230 C

The MSE 230 C is equipped with an electronic overload cutout to monitor motor temperature and power consumption.

21.1.1 Check chain tension frequently

A new chain has to be retensioned more often than one that has been in use for some time.

21.1.2 Chain cold

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

21.1.3 Chain at operating temperature

The chain stretches and begins to sag. The drive links must not come out of the bar groove – 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 drive shaft and bearings.

21.2 After finishing work

► Disconnect the plug from the wall outlet. ► Slacken off the chain if you have retensioned it

► If the indicator lamp (1) stays on for longer

than 2 seconds in an overload situation, the power supply is interrupted and the saw is switched off automatically – release the trigger switch, then restart the saw.

► If the saw then restarts at a reduced RPM, it is

overheated and switches off automatically after about 10 seconds – release the trigger switch, allow the saw to cool down for about one minute, then restart. If the saw again restarts at a reduced RPM, it has not cooled down sufficiently – allow it to cool down for a long as necessary until it restarts at normal RPM.

The indicator lamp glows only as long as the trig‐ ger switch is operated.

The indicator lamp flashes briefly to confirm it is functioning every time the motor is switched on.

26 Maintaining and Sharpening the Saw Chain English

WARNING

It is absolutely essential to comply with the angles and dimensions specified below. If the saw chain is incorrectly sharpened – and in par‐ ticular if the depth gauge is set too low – there is a risk of increased kickback of the saw, with resulting risk of injury.

26.2 Chain pitch

► Ease the E-clip (1) off the shaft. ► Remove and inspect the washer (2) – replace

it if it shows signs of wear. ► Remove the chain sprocket (3). ► Install the new chain sprocket in the reverse

sequence.

26 Maintaining and Sharpen‐

ing the Saw Chain

26.1 Cutting effortlessly with a cor‐

rectly sharpened chain

A properly sharpened chain slices through wood effortlessly and requires very little feed pressure.

Do not work with a dull or damaged chain as it will increase the physical effort required, produce unsatisfactory results and a higher rate of wear. ► Clean the chain. ► Check the chain for cracks in the links and

damaged rivets. ► Replace any damaged or worn parts of the

chain and match the new parts to the shape

and size of the original parts.

Carbide-tipped saw chains (Duro) are particularly wear resistant. STIHL recommends you have your chain resharpened by a STIHL servicing dealer.

The chain pitch (a) is marked on the depth gauge end of each cutter.

depth gauge setting, cutter length and groove depth. It also cleans the guide bar groove and oil inlet holes.

26.6 File correctly

► Disconnect the plug from the wall outlet. ► Select sharpening tools according to chain

pitch. ► Clamp the bar in a vise if necessary. ► To rotate the chain – pull hand guard against

handle to disengage the chain brake Hold the

hand guard in this position – the coasting

brake is disengaged. ► Sharpen the chain frequently, take away as lit‐

tle metal as possible – two or three strokes of

the file are usually enough.

► Use a file holder

A file holder must be used for manual resharpen‐ ing (see table "Sharpening Tools"). The correct filing angles are marked on the file holder.

Use only special saw chain sharpening files. Other files have the wrong shape and cut.

26.5 For checking angles

Use a STlHL filing gauge (special accessory, see table "Sharpening Tools"). This is a universal tool for checking the filing and side plate angles,

28 0458-756-0121-B

► Hold the file horizontally (at a right angle to the

side of the guide bar) and file according to the

angles marked on the file holder. Rest the file

holder on the top plate and depth gauge. ► Always file from the inside to the outside of the

cutter. ► The file only sharpens on the forward stroke –

lift the file off the cutter on the backstroke. ► Avoid touching the tie straps and drive links

with the file. ► Rotate the file at regular intervals while filing to

avoid one-sided wear. ► Use a piece of hardwood to remove burrs from

the cutting edge. ► Check angles with the filing gauge.

All cutters must be the same length.

26 Maintaining and Sharpening the Saw Chain English

If the cutters are not the same length, they will have different heights. This makes the chain run roughly and can cause it to break. ► Find the shortest cutter and then file all other

cutters back to the same length. It is best to have this work done by a servicing dealer on an electric grinder.

26.7 Depth gauge setting

The depth gauge determines the height at which the cutter enters the wood and thus the thickness of the chip removed.

a Specified distance or setting between depth

gauge and cutting edge.

This setting may be increased by 0.2 mm (0.008") for cutting softwood in the mild weather season – no frost.

0.404 (10.26) 0.80 (0.031)

26.8 Lowering depth gauges

The depth gauge setting is reduced when the chain is sharpened. ► Use a filing gauge to check the setting every

time you sharpen the chain.

► Place a filing gauge (1) that matches the chain

pitch on the chain and press it against the cut‐

ter – if the depth gauge projects from the filing

gauge, the depth gauge has to be lowered.

Saw chains with humped drive link (2) – upper part of humped drive link (2) (with service mark) is lowered along with the depth gauge.

WARNING

The other parts of the humped drive link must not be filed since this may increase the kickback ten‐ dency of the saw.

► File down the depth gauge until it is level with

the filing gauge.

► File the top of the depth gauge parallel to the

stamped service marking (see arrow) – but do

not lower the highest point of the depth gauge

in this process.

English 27 Maintenance and Care

WARNING

The kickback tendency of the saw is increased if the depth gauges are too low.

► Place the filing gauge on the chain – the high‐

est point of the depth gauge must be level with the filing gauge.

► After sharpening, clean the chain thoroughly,

remove filings or grinding dust – lubricate the chain thoroughly.

► Before a long out-of-service period, clean the

chain and store it in a well-oiled condition.

35 General Power Tool Safety

Warnings

This chapter reproduces the pre-formulated, gen‐ eral safety precautions specified in the EN 60745 European standard for hand-held motor-oper‐ ated electric tools. STIHL is required by law to print these standardized texts verbatim.

The safety precautions and warnings on avoiding an electric shock given under "2) Electric Pre‐ cautions" do not apply to STIHL cordless electric power tools

36 0458-756-0121-B

35 General Power Tool Safety Warnings English

WARNING

Read all safety warnings and instructions. Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury.

Save all warnings and instructions for future ref‐ erence.

The term "power tool" in the warnings refers to your mains-operated (corded) power tool or bat‐ tery-operated (cordless) power tool.

35.1 1) Work area safety

a) Keep work area clean and well lit. Cluttered

or dark areas invite accidents.

b) Do not operate power tools in explosive

atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.

c) Keep children and bystanders away while

operating a power tool. Distractions can cause you to lose control.

35.2 2) Electrical safety

a) Power tool plugs must match the outlet.

Never modify the plug in any way. Do not use any adapter plugs with earthed (groun‐ ded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock.

b) Avoid body contact with earthed or grounded

surfaces, such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.

c) Do not expose power tools to rain or wet

conditions. Water entering a power tool will increase the risk of electric shock.

d) Do not abuse the cord. Never use the cord

for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entan‐ gled cords increase the risk of electric shock.

e) When operating a power tool outdoors, use

an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.

f) If operating a power tool in a damp location

is unavoidable, use a residual current device (RCD) protected supply. Use of an RCD reduces the risk of electric shock.

35.3 3) Personal safety

a) Stay alert, watch what you are doing and use

common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury.

b) Use personal protective equipment. Always

wear eye protection. Protective equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.

c) Prevent unintentional starting. Ensure the

switch is in the off-position before connecting to power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your finger on the switch or energising power tools that have the switch on invites accidents.

d) Remove any adjusting key or wrench before

turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury.

e) Do not overreach. Keep proper footing and

balance at all times. This enables better con‐ trol of the power tool in unexpected situa‐ tions.

f) Dress properly. Do not wear loose clothing or

jewellery. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.

g) If devices are provided for the connection of

dust extraction and collection facilities, ensure these are connected and properly used. Use of dust collection can reduce dustrelated hazards.

35.4 4) Power tool use and care

Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed.

b) Do not use the power tool if the switch does

not turn it on and off. Any power tool that cannot be controlled with the switch is dan‐ gerous and must be repaired.

c) Disconnect the plug from the power source

and/or the battery pack from the power tool before making any adjustments, changing accessories, or storing power tools. Such

0458-756-0121-B 37

English

preventive safety measures reduce the risk of starting the power tool accidentally.

d) Store idle power tools out of the reach of

children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dan‐ gerous in the hands of untrained users.

e) Maintain power tools. Check for misalign‐

ment or binding of moving parts, breakage of parts and any other condition that may affect the power tool's operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.

f) Keep cutting tools sharp and clean. Properly

maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.

g) Use the power tool, accessories, tool bits

etc. in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situa‐ tion.

35.5 5) Service

Have your power tool serviced by a qualified repair person using only identical replace‐ ment parts. This will ensure that the safety of the power tool is maintained.

35.6 Chain saw safety warnings

Keep all parts of the body away from the saw

–

hand on the rear handle and your left hand on the front handle. Holding the chain saw with a reversed hand configuration increases the risk of personal injury and should never be done. Hold the power tool by insulated gripping sur‐

–

faces only, because the saw chain may con‐ tact hidden wiring or its own cord. Saw chains contacting a "live" wire may make exposed metal parts of the power tool "live" and could give the operator an electric shock. Wear safety glasses and hearing protection.

Further protective equipment for head, hands, legs and feet is recommended. Adequate pro‐

tective clothing will reduce personal injury by flying debris or accidental contact with the saw chain. Do not operate a chain saw in a tree. Opera‐

–

tion of a chain saw while up in a tree may result in personal injury. Always keep proper footing and operate the

–

chain saw only when standing on a fixed, secure and level surface. Slippery or unstable surfaces such as ladders may cause a loss of balance or control of the chain saw. When cutting a limb that is under tension be

–

alert for spring back. When the tension in the wood fibres is released the spring loaded limb may strike the operator and/or throw the chain saw out of control. Use extreme caution when cutting brush and

–

saplings. The slender material may catch the saw chain and be whipped toward you or pull you off balance. Carry the chain saw by the front handle with

–

the chain saw switched off and away from your body. When transporting or storing the chain saw always fit the guide bar cover. Proper handling of the chain saw will reduce the likelihood of accidental contact with the moving saw chain. Follow instructions for lubricating, chain ten‐

sioning and changing accessories. Improperly tensioned or lubricated chain may either break or increase the chance for kickback. Keep handles dry, clean and free from oil and

–

grease. Greasy, oily handles are slippery causing loss of control. Cut wood only. Do not use chain saw for pur‐

–

poses not intended. Example: do not use chain saw for cutting plastic, masonry or nonwood building materials. Use of the chain saw for operations different than intended could result in a hazardous situation.

35.7 Causes and operator preven‐ tion of kickback:

Kickback may occur when the nose or tip of the guide bar touches an object, or when the wood closes in and pinches the saw chain in the cut.

Tip contact in some cases may cause a sudden reverse reaction, kicking the guide bar up and back towards the operator.

Pinching the saw chain along the top of the guide bar may push the guide bar rapidly back towards the operator.

Either of these reactions may cause you to lose control of the saw which could result in serious

personal injury. Do not rely exclusively upon the safety devices built into your saw. As a chain saw user, you should take several steps to keep your cutting jobs free from accident or injury.

Kickback is the result of tool misuse and/or incor‐ rect operating procedures and can be avoided by taking proper precautions as given below:

Maintain a firm grip, with thumbs and fingers

–

encircling the chain saw handles, with both hands on the saw and position your body and arm to allow you to resist kickback forces. Kickback forces can be controlled by the oper‐ ator, if proper precautions are taken. Do not let go of the chain saw. Do not overreach and do not cut above shoul‐

–

der height. This helps prevent unintended tip contact and enables better control of the chain saw in unexpected situations. Only use replacement bars and chains speci‐

–

fied by the manufacturer. Incorrect replace‐ ment bars and chains may cause chain break‐ age and/or kickback. Follow the manufacturer's sharpening and

–

maintenance instructions for the saw chain. Decreasing the depth gauge height can lead to increased kickback.
