Mixing Fuel/Filling With Fuel (cont.)

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!

3.Refer to following chart for examples of 50:1 fuel to oil mix quantities.

4.Place the saw on a hard surface with the fuel cap up and wipe any chips or debris from around the fuel cap.

5.

Remove the fuel cap and fill the tank

 

with clean, fresh 2-cycle fuel mix.

 

Avoid overfilling and fuel spillage.

6.

Wipe any spilled fuel and move the

 

saw at least 10 feet (3 meters) from

 

the fueling point before starting the

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.

Bar Oil/Filling With Oil

Oil Requirements

⬛ When available, use Shindaiwa

Premium bar & chain oil.

⬛ When Shindaiwa oil is not available,

use a premium 30-weight oil

OPERATION

NOTE:

Cutting downed timber, or Òbucking,Ó 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.

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.

Oil Cap

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.

LIMBING

the saw.

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!

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.

⬛ 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!
