Chain Saw WG303E
8. Use extreme caution when cutting 
brush and saplings. The slender 
material may catch the saw chain and 
be whipped toward you or pull you off 
balance.
9. Carry the chain saw by the front 
handle with the chain saw switched 
off and away from your body. When 
transporting or storing the chain saw 
always fit the guide bar cover. Proper 
handling of the chain saw will reduce the 
likelihood of accidental contact with the 
moving saw chain.
10.Follow instructions for lubricating, 
chain tensioning and changing 
accessories. Improperly tensioned 
or lubricated chain may either break or 
increase the chance for kickback.
11.Keep handles dry, clean, and free 
from oil and grease. Greasy, oily 
handles are slippery causing loss of 
control.
12.Cut wood only. Do not use chain 
saw for purposes not intended. For 
example: do not use chain saw for 
cutting plastic, masonry or non-wood 
building materials. Use of the chain saw 
for operations different than intended 
could result in a hazardous situation.
13. Using of a residual current device with 
a tripping current of 30 mA or less is 
recommended.
Causes and operator prevention of 
kickback
Kickback may occur when the nose or tip of 
the guide bar touches an object, or when the 
wood closes in and pinches the saw chain in 
the cut.
Tip contact in some cases may cause a 
sudden reverse reaction, kicking the guide 
bar up and back towards the operator.
Pinching the saw chain along the top of the 
guide bar may push the guide bar rapidly 
back towards the operator.
Either of these reactions may cause you to 
lose control of the saw which could result 
in serious personal injury. Do not rely 
exclusively upon the safety devices built into 
your saw. As a chain saw user, you should 
take several steps to keep your cutting jobs 
free from accident or injury.
Kickback is the result of tool misuse and/or 
incorrect operating procedures or conditions 
and can be avoided by taking proper 
precautions as given below:
-  Maintain a firm grip, with thumbs 
and fingers encircling the chain saw 
handles, with both hands on the saw 
and position your body and arm to 
allow you to resist kickback forces. 
Kickback forces can be controlled by the 
operator, if proper precautions are taken. 
Do not let go of the chain saw.
-  Do not overreach and do not cut 
above shoulder height. This helps 
prevent unintended tip contact and 
enables better control of the chain saw in 
unexpected situations.
-  Only use replacement bars and 
chains specified by the manufacturer. 
Incorrect replacement bars and chains 
may cause chain breakage and/or kickback.
-  Follow the manufacturer’s sharpening 
and maintenance instructions for the 
saw chain. Decreasing the depth gauge 
height can lead to increased kickback.

Instructions concerning the proper 
techniques for basic felling, limbing, and 
cross-cutting
1. Felling a tree
When bucking and felling operations are 
being performed by two or more persons at 
the same time, the felling operations should 
be separated from the bucking operation by 
a distance of at least twice the height of the 
tree being felled. Trees should not be felled in 
a manner that would endanger any person, 
strike any utility line or cause any property 
damage. If the tree does make contact with 
any utility line, the company should be 
notified immediately.
The chain saw operator should keep on the 
uphill side of the terrain as the tree is likely to 
roll or slide downhill after it is felled.
An escape path should be planned and 
cleared as necessary before cuts are started. 
The escape path should extend back and
