4.
Do
not allow other persons to be near the chain saw when starting or cutting with the chain saw. Keep bystanders and
animals out of the work area.
5.
Do not start cutting until you have a clear work area, secure footing, and a planned retreat path from the falling tree.
6.
Holdthechain saw firmly with both hands, the right hand left hand engine is running. Use a firm grip with thumbs and fingers encircling the chain saw handles.

Devices for reducing the risk of kickback
STIHL has developes a chain stopping system designed to reduce the risk of injuryina kickback situation. The device is
called a Quickstop. The Quickstopisavailableasan optiononmany STIHLsaws. This device does not prevent kickback, butwill stop the chain in some kickback situations if the operator's left handisin
position to activate the Quick-
stop leverbycontacting the front hand guard.
When a kickback occurs, the chain saw rotates plane of the
bar.
The left hand, when properly gripping the front handle behind the front handguard should engage the Quickstop lever.This activates the Quickstop and stops the chain (see ill.
14).
STIHL has developed guide bars with a small radius nose. These guide bars are designed to reduce the kickback tendency and are available
as
an option.
STIHL has developed chains with cutters whose configu­ration are designed to reduce kickback forces. These chains are available as
12
an
option.
However, even if your saw has a "Quickstop" a narrow nose bar or a guard-link or a pro-guard chain, it does not guarantee that you will not
be
injuredbya "kickback" arid therefore, you should observe all of the precautions to
prevent kickback discussed previously.
Wammgl
Chain saw kickback may cause serious or fatal injury. To
reduce the risk of kickback injuries STIHL recommends
in
the
that you equip your saw with a narrow nose
bar,
low profile chain or other chain designedtoreduce kickback forces, and a STIHL QuicRstop.
Pushback:
Pushback occurs when the chain on the top of the bar
is suddenly stopped when it is pinched, caught or encounters a foreign objectinthe wood. The reaction of the chain drives the saw straight back toward the operator causing loss of saw control. Pushback frequently occurs when top of the barisused for cutting (see ill.

At very low outside temperatures do not open the choke fully immediately after starting. First allow engine to warm up for a brief period with very little throttle (release). Then release throttle trigger and open the choke. A new engine or one which has been run until the fuel tank is
dry will not start first time after refueling because the carburetor's diaphragm pump has to be primed with fuel by cranking the engine over several times on the starter.

Like any other cutting tool, the saw chain is sUbject normal wear. A properly sharpened chain will eat into the wood and require very little effort on the part of the operator. with a dull or damaged chain.
A carefully sharpened saw chain offers many benefits, a higher cutting capacity, clean and smooth cuts - this means less operator effort, a lower fuel consumption and minimum wear.
There are a few crucial angles which must be maintained in They are explained below.
Filing angle
The filing angle on the Oilomatic-Picco chainis35°; the chain is initially sharpened to this angle before leaving the factory. However, if you use the chain primarily for cutting hardwood or frozen timber, it is best to sharpen an angle of 30°.
Always make sure that the filing angle is exactly the same

All cutters mustbe filed to the same length. As the top plate slopes downward to the rear (clearance angle) the cutter heights will be uneven if the cutter lengths are different. If the cutters are not all the same height the chain will run roughly and eventually break.

The bestcutting results are obtained with the depth gauges set to this value. However, the depth gauge setting may be increased by 0.2 mm for cutting softwood conditions.
