• Make sure working place is free from any obstacles. Top of the guide bar should not
touch a tree or another solid object.

6. ASSEMBLY AND OPERATION
1. Before and during operation follow the requirements of the section «SAFETY
INSTRUCTIONS».
2. Before operation it is necessary to perform the assembly procedure and adjust the
chain tension in the following order:
• put on gloves for hands protection;
• make sure that the chain brake lever is released toward the front handle;
• remove chain bar clamp nuts and case screws, remove the case;
• using a screwdriver, turn the adjusting screw, till the boss reaches end of its travel
toward the drive sprocket;
• install the guide bar;
• install the saw chain in such a way so that cutting edges of the chain were facing
clockwise (chain should be loose);
• install the case and fix it with screws. The chain should stay on the bar and the boss
of the chain tension should fit into the whole of the bar;
• tighten the clamp nuts with fingers and start the adjustment procedure.
3. Chain adjustment (correct tension is very important, that is why it should be
checked before every operation as well as during the operation):
• put on gloves for hands protection;
• raise the bar end and tighten the chain by turning the tension adjustment screw;
• keeping the bar at the top carefully tighten the nuts;
• after adjustment move the chain back and forth on the guide bar and make sure it
moves freely and engages with the sprocket teeth. If the chain movement is heavy then
the tension is too high and should be loosened.
Note: new chain will stretch so adjust the chain approximately after five cuts.
Further increase adjustment intervals.
Attention: Wrong chain tension leads to rapid wear of chain, guide bar and
sprocket.

• For optimum result use 25:1 mixture of two-cycle oil and gasoline. Always use
unleaded gasoline with octane number 85 or higher. Usage of leaded gasoline is
allowed. Before usage store the gasoline not longer than 30 days.
