Jonsered CS 2141 EPA II Manuel D’Utilisation

32 – 

English

During cold weather and under powder snow conditions, 
operating problems can arise due to:

•

Too low engine temperature.

•

Icing of the air filter and carburettor.

Special measures are therefore often required:

•

Partly mask the air inlet on the starter to increase the 
working temperature of the engine.

°°°°

°°°°

The cylinder cover is designed so it can be adjusted for 
running in cold weather. Twist the winter flap so that 
preheated air from the cylinder can pass into the carburettor 
space preventing icing of the air filter, etc.

°°°°

°°°°

For temperatures below -5

°

C and/or in snow conditions there 

is also:

•

a special cover (A) for the starter housing

•

a winter plug (B) for the air nozzle that is fitted as shown.

These reduce the flow of cooling air and prevent large 
amounts of snow from being sucked into the carburettor 
space. CAUTION!  When the winter plug is fitted the winter 
flap must be open!

1

Check the throttle trigger for smooth operation. If any 
binding occurs, or if engine fails to return to idle, the 
machine should be taken to your dealer,  befor it is used 
again. Also,  be sure that the trigger cannot be pulled until 
the throttle trigger lockout is depressed.

2

Clean the chain brake and check that it operates safely. 
Make sure that the chain catcher is undamaged, and 
replace it if necessary.

3

Clean the air filter. Replace if necessary.

4

The bar should be turned daily for more even wear. Check 
the lubrication hole in the bar, to be sure it is not clogged. 
Clean the bar groove. If the bar has a sprocket tip, this 
should be lubricated.

5

Check that the bar and chain are getting sufficient oil.

6

Sharpen the chain and check its tension and condition. 
Check the drive sprocket for excessive wear and replace 
if necessary.

7

Clean the air intake on the starter. Check the starter and 
starter cord for wear or damage.

8

Check that nuts and screws are tight.

9

Test the stop switch to be sure it shuts off the engine.

10 Check the cooling system on chain saws with catalytic 

converters.

IMPORTANT! If the special winterising kit has been fitted or 
any measures have been taken to increase the temperature 
these changes must be reversed before the machine is 
used in normal temperature conditions. Otherwise there is 
a risk of overheating, resulting in severe damage to the 
engine.

IMPORTANT! Any maintenance other than that described in 
this manual must be carried out by your servicing dealer 
(retailer).
