Checking the chain brake The chain brake must be checked before every use of the saw! Start the engine as described above (have a secure footing, place the chain saw on the ground so that the chain and guide bar are not near anything). 6 Hold the front handle Þrmly, with your other hand on the rear grip. Let the engine run at medium speed and push the handguard (6) in the direction of the arrow using the back of your hand, until the chain brake engages. The chain should now stop immediately. Bring the engine back to idle and release the chain brake. Caution: If the chain does not stop immediately in this test, turn off the engine immediately. Do NOT use the chain saw in this condition! Contact a MAKITA service centre. Working in winter In order to prevent carburetor icing in conditions of low temperature combined with high humidity, and below + 5°C in order to get up to operating temperature faster, heated air can be taken from the cylinder. Remove the cover (see "Cleaning the air Þlter"). Remove the insert (7) and insert it as shown for winter operation. If the temperature is above + 5°C (40°F) the engine needs to induct cold air. If this is not done, the cylinder and piston can be damaged! For temperatures above + 5°C (40°F) turn the insert 180° so that after it is inserted the induction opening (8) is closed. Put the cover back on. Symbol visible - Normal operation Symbol visible - Winter operation 7 8 23
