G2500 / G2500 OPS

This saw is equipped with a chain brake that will stop the chain in the event of kickback if operating prop-

erly. You must check the chain brake operation before each usage by run- ning the saw at full the throttle for I - 2 seconds and pushing the front hand guard forward. The chain should stop immediately with the engine at full speed. If the chain is slow to stop or does not stop, re- place the brake band and clutch drum before use.

It is extremely important that the chain brake be checked for proper

operation before each use and that the chain be sharp in order to main- tain the kickback safety level of this saw. Removal of the safety devices, inadequate maintenance, or incor- rect replacement of the bar or chain may increase the risk ot serious per- sonal injury due to kickback.

Cutting the limbs of Fallen Tree

1.Decide the felling direction considering the wind, lean of the tree, location of heavy branches, ease of completing the task after felling and other factors.

2.While clearing the area around the tree, arrange a good foothold and retreat path.

3.Make a notch cut one-third of the way into the tree on the felling side.

4.Make a felling cut from the opposite side of the notch and at a level slightly higher than the bottom of the notch.

WARNING

When you fell a tree, be sure to warn neighboring work- ers of the danger.

Bucking and Limbing

WARNING

Always ensure your foothold. Do not stand on the log.

Be alert to the rolling over of a cut log. Especially when working on a slope, stand on the uphill side of the log.

Follow the instructions in “For Safe Operation” to avoid kickback of the saw.

Before starting work, check the direction of bending force inside the log to be cut. Always finish cutting from the opposite side of the bending direction to prevent the guide bar from being caught in the cut.

GB-14

First check to which side the limb is bent. Then make the initial cut from the bent side and finish by sawing from the opposite side.

WARNING

Be alert to the springing back of a cut limb.

Pruning of Standing Tree

WARNING

Do not use an unstable foothold or ladder.

Do not overreach.

Do not cut above shoulder height.

Always use both your hands to hold the saw.
