cally trained and equipped to do  
so!  
Use only Shindaiwa-recommended  
parts when repairing or servicing  
this saw.  
Improper maintenance, use of  
nonconforming replacement  
components, or the removal of  
safety devices, such as the chain  
brake or any of the chain brake  
components, could result in  
serious injury.  
Do not use this saw if the saw  
chain continues to move after the  
throttle control trigger is released.  
Using a depth  
gauge joiner  
CHN-18  
Use extra care when cutting a  
limb that is under tension! A limb  
under tension could spring back  
suddenly, causing you to lose  
control of the saw!  
CHN-19  
Never allow any part of your body  
near the clutch cover of an  
operating saw.  
Using a flat file to round  
the front corner on a  
depth gauge  
Use extreme caution when cutting  
smaller brush and saplings! Small-  
diameter material may catch in the  
chain and be whipped toward you  
or pull you off balance, causing  
you to lose control of the saw!  
Never operate a saw with dam-  
aged or missing anti-vibration  
cushions. Long-term exposure to  
vibration can damage your hands.  
Sharpening Technique  
1. Using a 5/32" round file, sharpen all 2. After all cutters are sharpened, use  
cutters to a 30° angle .  
a depth gauge joiner (Oregonா  
p/n 106738 or equivalent) to  
measure the height of each depth  
gauge.  
Always maintain a firm footing  
while operating this saw! Ladders  
and other temporary platforms can  
shift unexpectedly, and are not  
recommended!  
Operate the saw only in a well  
ventilated area.  
IMPORTANT!  
File all cutters to the same angle and  
depth! Unequal filing may cause the  
saw to vibrate or cut erratically!  
3. As required, lower the depth gauges  
to a height of 0.020"  
NOTE:  
(0.5 mm). Use a flat file; Oregonp/  
n 12211 or equivalent.  
For consistent filing angles, use a filing  
guide such as Oregonா  
p/n 37534 or equivalent.  
4. After all depth gauges have been  
adjusted, use a flat file to round each  
depth gauge leading edge to its  
original curvature and angle.
