STIHL MS 250 manual Important Adjustments

Once the engine has started, immediately blip the throttle trigger, which should release the Master Control lever to the run position and allow the engine to slow down to idle.

WARNING

When you pull the starter grip, do not wrap the starter rope around your hand. Do not let the grip snap back, but guide the starter rope to rewind it properly. Failure to follow this procedure may result in injury to your hand or fingers and may damage the starter mechanism.

Important Adjustments

WARNING

To reduce the risk of personal injury from loss of control and / or contact with the running cutting tool, do not use your chain saw with incorrect idle adjustment. At correct idle speed, the cutting tool should not move. For directions on how to adjust idle speed, see the appropriate section of your instruction manual.

If you cannot set the correct idle speed, have your STIHL dealer check your chain saw and make proper adjustments and repairs.

Holding and Controlling the Chain Saw

Always hold the chain saw firmly with both hands when the engine is running. Place your left hand on the front handle bar and your right hand on the rear handle and throttle trigger.

Left-handers should follow these instructions too. Wrap your fingers tightly around the handles, keeping the handles cradled between your thumb and forefinger. With your hands in this position, you can best oppose and absorb the push, pull and kickback forces of your saw without losing control (see section on reactive forces).

WARNING

To reduce the risk of seri- ous or fatal injury to the operator or bystanders from loss of control, never use the chain saw with one hand. It is more difficult for you to control reactive forces and to prevent the bar and chain from skating or bouncing along the limb or log.

WARNING

To reduce the risk of cut injuries, keep hands and feet away from the cutting tool. Never touch a moving cutting tool with your hand or any other part of your body.

WARNING

Keep proper footing and balance at all times. Special care must be taken in slippery conditions (wet ground, snow) and in difficult, overgrown terrain. Be extremely cautious when working on slopes or uneven ground. Watch for hidden obstacles such as tree stumps, roots, rocks, holes and ditches to avoid stumbling. There is increased danger of slipping on freshly debarked logs. For better footing, clear away fallen branches, scrub and cuttings. Use extreme caution when cutting small-size brush, branches and saplings because slender material may catch the saw chain and be whipped toward you or pull you off balance.

WARNING

Take extreme care in wet and freezing weather (rain, snow, ice). Put off the work when the weather is windy, stormy or rainfall is heavy.
