Mixing Fuel - Shindaiwa 357 Owner's/Operator's Manual

Bucking
WARNING!
Always cut downed timber from the uphill side of the tree!
Downed timber may shift or roll unpredictably during cutting or
handling. Be alert for potential injury from rolling or shifting logs!
First Cut
CHN-12
Second Cut
If the log is well supported, start your
cut from the top of the log. Keeping
the guide bar parallel to the ground,
cut straight down but do not allow the
saw to cut into the ground.
NOTE:
Cutting downed timber, or "bucking,"
increases the possibility of the wood
settling and pinching the guide bar.
Driving one or more soft plastic or
wooden bucking wedges can help
prevent bar-pinching during a cut.
LIMBING
Limbing a standing tree is usually
accomplished in the same manner as
bucking, with a third and final cut used
to remove the remaining stub of the
limb.
WARNING!
Do not overreach or
attempt to cut above
shoulder height!

Second Cut (overbuck)
CHN-13
First Cut (underbuck), about
1/3 tree diameter
Use two cuts when bucking the
outboard end of an unsupported log.
Your first cut should be an under-
buck. Cut the underbuck about 1/3
the diameter of the tree, then move to
the top of the log and finish the cut by
bucking down (overbucking) to the
first cut.
NOTE:
When cutting unsupported logs or
limbs, starting with an underbuck cut
will minimize the possibility of the
wood splitting during the bucking cut.
Use two cuts when bucking near the
inboard end of an unsupported log.
■ Make the first cut as an underbuck
about 1/3 the diameter of the log.
■ Finish the job from above with an
overbuck joining the first cut.
Mixing Fuel/Filling With Fuel (cont.)
3. Refer to following chart for
examples of 50:1 fuel to oil mix

Oil Requirements
When available, use Shindaiwa
Premium bar & chain oil.
When Shindaiwa oil is not available,
use a premium 30-weight oil
specifically blended for bar & chain
lubrication.
For cold weather operation, bar oil
may be thinned by mixing with
clean kerosene at a ratio of 1:1.
Filling the Oil Reservoir
Filling the Oil Reservoir Place the
saw on its side (clutch cover
down), and wipe any chips or
debris from around the oil cap.
Remove the oil cap at the front of
the saw.
Fill the oil reservoir with bar &
chain oil, and replace the cap.
Wipe spilled oil from handles and
controls before starting the saw.
CAUTION!
Proper lubrication is critical to
the performance and service life
of your saw's oil pump, guide
bar, and saw chain! Always use
a high quality lubricating oil
designed for saw chain lubrica-
tion! Never use dirty or re-
claimed oil!
