Bar 

The smaller the tip radius the lower the chance of kick-
back.

Chain

A chain is made up of a number of links, which are 
available in standard and low-kickback versions.

IMPORTANT! No saw chain design elimi-
nates the danger of kickback.

WARNING! Any contact with a rotating saw 
chain can cause extremely serious injuries.

SHARPENING YOUR CHAIN AND ADJUST-
ING DEPTH GAUGE SETTING

WARNING! Always wear gloves, when work-
ing with the chain, in order to protect your 
hands from injury.

General information on sharpening cutting teeth
•  Never use a blunt chain. When the chain is blunt 

you have to exert more pressure to force the bar 
through the wood and the chips will be very small. If 
the chain is very blunt it will produce wood powder 
and no chips or shavings.

•  A sharp chain eats its way through the wood and 

produces long, thick chips or shavings.

•  The cutting part of the chain is called the cutter and 

consists of a cutting tooth and the depth gauge.

  The cutters cutting depth is determined by the dif-

ference in height between the two (depth gauge set-
ting).

When you sharpen a cutting tooth there are four impor-
tant factors to remember.
1 Filing angle
2 Cutting angle
3 File position
4 Round

 le diameter

It is very dif

fi

 cult to sharpen a chain correctly without the 

right equipment. We recommend that you use our 

fi

 le 

gauge. This will help you obtain the maximum kickback 
reduction and cutting performance from your chain.

WARNING! Departure from the sharpening 
instructions considerably increases the risk 
of kickback.

•  Check that the chain is correctly tensioned. A slack 

chain will move sideways, making it more dif

fi

 cult to 

sharpen correctly.

• Always 

fi

 le cutting teeth from the inside face. Re-

duce the pressure on the return stroke. File all the 
teeth on one side 

fi

 rst, then turn the chain saw over 

and 

fi

 le the teeth on the other side.

•  File all the teeth to the same length. When the length 

of the cutting teeth is reduced to 4 mm (0.16") the 
chain is worn out and should be replaced.

WARNING! The risk of kickback is increased 
if the depth gauge setting is too large!

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 

fi

 ngers, hands or 

wrists. These symptoms may be increased in cold tem-
peratures.

Stop switch

Use the stop switch to switch off the engine.

Muf

fl

 er

The muf

fl

 er is designed to reduce noise levels and to 

direct exhaust fumes away from the user.

WARNING! The exhaust fumes from the en-
gine are hot and may contain sparks which 
can start a 

fi

 re. Never start the machine in-

doors or near combustible material!

CAUTION! The muf

fl

 er gets very hot during 

and after use. This also applies during idling. 
Be aware of the 

fi

 re hazard, especially when 

working near 

fl

 ammable substances and/or vapours.

WARNING! Never use a saw without a muf-

fl

 er, or with a damaged muf

fl

 er.  A  damaged 

muf

fl

 er may substantially increase the noise 

level and the 

fi

 re hazard. Keep 

fi

 re 

fi

 ghting  equipment 

handy. If a spark arrestor screen is required in your ar-
ea, never use the saw without or with a broken spark 
arrestor screen.

CUTTING EQUIPMENT GENERAL RULES

•  Only use cutting equipment recommended by us!
•  Keep the chain’s cutting teeth properly sharpened!
•  Maintain the correct depth gauge setting! Follow our 

instructions and use the recommended depth gauge 
clearance. Too large a clearance increases the risk 
of kickback.

•  Keep the chain properly tensioned! If the chain is 

slack it is more likely to jump off and lead to in-
creased wear on the bar, chain and drive sprocket.

•  Keep cutting equipment well lubricated and properly 

maintained! A poorly lubricated chain is more likely 
to break and lead to increased wear on the bar, 
chain and drive sprocket.

CUTTING EQUIPMENT DESIGNED 
TO REDUCE KICKBACK

The only way to avoid kickback is to make sure that the 
kickback zone of the bar never touches anything.
By using cutting equipment with ”built-in” kickback 
reduction and keeping the chain sharp and wellmain-
tained you can reduce the effects of kickback.
