Checking the tension:

SFit bottom of drive links between the teeth in the sprocket in the nose of the guide bar.

SFit chain drive links in bar groove.

SPull the bar forward until the chain is snug in the guide bar groove. Ensure all drive links are in the bar groove.

SNow, install chain brake making sure the

adjusting pin is positioned in the lower hole in the guide bar. Remember this pin moves the bar forward and backward as the screw is turned.

SInstall chain brake nuts and finger tighten only. Once the chain is tensioned, you will need to tighten chain brake nuts.

CHAIN TENSION (Including units with chain already installed)

NOTE: When adjusting chain tension, make sure the chain brake nuts are finger tight only. Attempting to tension the chain when the chain brake nuts are tight can cause damage.

Checking the tension:

Use the screwdriver end of the chain adjust- ment tool (bar tool) to move the chain around the bar. If the chain does not rotate, it is too tight. If too loose, the chain will sag below the bar.

Adjusting the tension:

Chain tension is very important. Chain stretches during use. This is especially true during the first few times you use your saw. Always check chain tension each time you use and refuel your saw.

You can adjust the chain tension by loosening the chain brake nuts and turning the adjusting screw 1/4 of a turn while lifting up on the bar.

SIf chain is too tight, turn adjusting screw 1/4 turn counterclockwise.

SIf chain is too loose, turn adjusting screw 1/4 turn clockwise.

S Lift up the tip of the bar and tighten the chain brake nuts with the bar tool.

SRecheck chain tension.

BAR AND CHAIN LUBRICATION WARNING: If the saw is operated with a loose chain, the chain could jump off the guide bar and result in serious injury.

Manual background WARNING: Muffler is very hot dur- ing and after use. Do not touch the muffler or allow combustible material such as dry grass or fuel to do so.

Manual background WARNING: Remove fuel cap slow- ly when refueling.

FUELING ENGINE

This engine is certified to operate on unleaded gasoline. Before operation, gasoline must be mixed with a good quality

2-cycle air-cooled engine oil. We recommend HusqvarnaR brand oil. If you do not use this oil, use a good quality 2-cycle air-cooled oil designed to be mixed at a ratio of 40:1. A 40:1 ratio is obtained by mixing 0,125 liter of oil with 5 liters of unleaded gasoline. DO NOT USE automotive or boat oil. These oils will cause engine damage. When mixing fuel follow the instructions printed on the container. Always read and follow the safety rules listed under HANDLE FUEL WITH CAUTION.

BAR AND CHAIN LUBRICATION

The bar and chain require continuous lubri- cation. Lubrication is provided by the auto- matic oiler system when the oil tank is kept filled. Lack of oil will quickly ruin the bar and chain. Too little oil will cause overheating shown by smoke coming from the chain and/ or discoloration of the bar.

Only use Bar and Chain Oil for bar and chain lubrication.
