Poulan 3400 - Manual (Page 21)

CAUTION:I Never set the High Speed Mixture
Screw less than 7/8 turn open. This is too lean
a setting and will damage your engine.
6. IDLE SPEED ADJUSTMENT—III
Recheck for proper idle mixture setting. ^
NOTE: It may be necessary to repeat Idle Speed
Adjustment — I and Low Speed Mixture Adjust­
ment.
7. CHECK ACCELERATION
Adjust if there is a slight hesitation, by turning the
Low Speed Mixture Screw 1 /16 of a turn at a time
ojunterclockwise until you have smooth
acceleration.
NOTE: Check to be sure the chain is not turning
when engine is idling.Jf chain moves at idle speed,
repeat Idle Speed Adjustment—II.
AIR FILTER
• A dirty air filter:
— reduces cutting power
— increases fuel consumption
• Clean the Air Filter:
—frequently, especially under very dusty condi­
tions.
—always after 10 tanks of fuel mixture or 5 hours
of operation, whichever is less.
1 CAUTION^ Never operate the unit without the
air filter in place to avoid damage to the engine.
Items Required: soft bristled brush, such as a paint
brush.
1. Clean off the carburetor cover and the area around
it.
2 . Close choke to prevent dirt from entering the car­
buretor.
3. Remove the carburetor cover. Figure 50.
4. Removetheairfiltercarefully.
5. Soak the filter in soap and water.
CAUTION:! Do not use gasoline or other flam­
mable liquid to clean the filter to avoid creating
afire hazard.
6 . Brush away all dust and debris from the filter.
7. Allow filter to dry.
8 . Brush away all debris from surfaces which were
covered by the carburetor cover.
9. Replace filter and carburetor cover.
G. COUNTER-VIBE® ANTI-VIBRATION SYSTEM
This saw is equipped with a counter vibration
system consisting of 5 isolator mounts.
Figure 51.
The Isolator Mounts reduce engine and chain vibration
similar to the way shock absorbers on a car reduce jolts
and bumps in the road.
1. Check isolators each time the saw is used.
2 . Replace isolators when:
—vibration increases
—mounts develop an out of round or swollen
shape usually caused from exposure to gasoline
and oil for long periods of time.
3 . Replace ail five isolators when a failure to one
occurs.
H. STORAGE
When your saw is to be stored for over 30 days al­
ways:
1- Drain fuel tank in a safe manner (see “Impor­
tant Points,” page 9).
2 . Start engine and allow to run at idle speed
until the engine stops.
NOTE: This will remove most of the fuel from the
fuel system.
CAUTION:I Wear protective gloves when han­
dling the chain. The chain is sharp and can cut
you even when it is not moving.
3. Drain oil tank.
4. Remove,, clean, and dry the bar and chain.
5. Store the chain in a container filled with oil to pre­
vent rust.
6 . Apply a coating of oil to the entire surface of the bar
and wrap it in heavy paper, cloth or plastic.
7. Clean the outside surfaces of the engine.
8 . Store frie saw in a dry place out of the reach of chil-.
dren and away from where fuel vapors can reach
open flames from hot water heaters, furnaces, etc.
