Lack of concentration can lead to kickback if the kick-
back zone of the bar accidentally touches a branch, 
nearby tree or some other object.
Have control over the workpiece. If the pieces you
intend to cut are small and light, they can jam in the 
saw chain and be thrown towards you. This is not nec-
essarily dangerous in itself, but you may be surprised 
and lose control of the saw. Never saw stacked logs or 
branches without 

fi

 rst separating them. Only saw one 

log or one piece at a time. Remove the cut pieces to 
keep your working area safe.
4 Never use the chain saw above shoulder height and 
try not to cut with the tip of the bar. Never use the chain 
saw one-handed!
5 You must have a steady stance in order to have full 
control over the chain saw. Never work standing on a 
ladder, in a tree or where you do not have 

fi

 rm ground 

to stand on.
6 Always use a fast cutting speed, i.e. full throttle.
7 Take great care when you cut with the top edge of the 
bar, i.e. when cutting from the underside of the object. 
This is known as cutting on the push stroke. The chain 
tries to push the chain saw back towards the user. If the 
saw chain is jamming, the saw may be pushed back 
at you.
8 Unless the user resists this pushing force there is a 
risk that the chain saw will move so far backwards that 
only the kickback zone of the bar is in contact with the 
tree, which will lead to a kickback.
Cutting with the bottom edge of the bar, i.e. from the 
top of the object downwards, is known as cutting on 
the pull stroke. In this case the chain saw pulls itself 
towards the tree and the front edge of the chain saw 
body rests naturally on the trunk when cutting. Cutting 
on the pull stroke gives the operator better control over 
the chain saw and the position of the kickback zone.
9 Follow the instructions on sharpening and maintain-
ing your bar and chain. When you replace the bar and 
chain use only combinations that are recommended by 
us.

GENERAL

The user must only carry out the maintenance and 
service work described in this Operator’s Manual. More 
extensive work must be carried out by an authorised 
service workshop.

CARBURETTOR ADJUSTMENT

Your DeFort product has been designed and manufac-
tured to speci

fi

 cations that reduce harmful emissions.

FUNCTION

•  The carburettor governs the engine’s speed via the 

throttle control. Air and fuel are mixed in the car-
burettor. The air/fuel mixture is adjustable. Correct 
adjustment is essential to get the best performance 
from the machine.

•  The T-screw regulates the throttle setting at idle 

speed. If the T-screw is turned clockwise this gives 
a higher idle speed; turning it anti-clockwise gives a 
lower idle speed.

Basic settings and running in

The basic carburettor settings are adjusted during test-
ing at the factory. Fine adjustment should be carried 
out by a skilled technician.
Rec. idle speed: See the Technical data section.
Fine adjustment of the idle speed T
Adjust the idle speed with the T-screw. If it is neces-
sary to re-adjust, turn the T-screw clockwise while 
the engine is running, until the chain starts to rotate. 
Then turn anticlockwise until the chain stops. When 
the idle speed is correctly adjusted the engine should 
run smoothly in every position and the engine speed 
should be safely below the speed at which the chain 
starts to rotate.

WARNING! Contact your servicing dealer, if 
the idle speed setting cannot be adjusted so 
that the chain stops. Do not use the chain 

saw until it has been properly adjusted or repaired.

MAINTENANCE SCHEDULE

The following is a list of the maintenance that must be 
performed on the machine. Most of the items are de-
scribed in the Maintenance section.
