Chain Tension; Working Techniques - Poulan Pro PD4016 Instruction Manual

n Starting a Flooded Engine
The engine may be flooded with too much fuel if it has not
started after 10 pulls.
Flooded engines can be restarted by pushing the blue choke
lever in completely to the OFF CHOKE position and then
following the warm engine starting procedure listed above.
Ensure the red ON/STOP switch is in the ON position.
Starting could require pulling the starter rope handle many
times depending on how badly the unit is flooded. If the
engine fails to start, refer to the TROUBLESHOOTING
TABLE or call the consumer assistance help line.

CHAIN TENSION

It is normal for a new chain to stretch during the first 15
minutes of operation. You should check your chain tension
each time before you start the chainsaw. See the chain
tensioning instructions in the ASSEMBLY section.
WARNING! If the saw is operated with a loose
chain, the chain could jump off the guide bar
and result in serious injury to the operator
and/or damage the chain, making it unusable.
CHECKING THE CHAIN BRAKE
The chain brake must be checked before each use. The
engine must be running when performing this procedure.
This is the only instance when the saw should be placed on
the ground with the engine running.
PRACTICING YOUR CUTS
Practice cutting a few small logs using the following
techniques to get the "feel" of using your saw before you
begin a major sawing operation.
Squeeze the throttle trigger and allow the engine to reach
·
full speed before cutting.
Begin cutting with the saw frame against the log.
·
Keep the engine at full speed the entire time you are
·
cutting.
Allow the chain to cut for you. Exert only light downward
·
pressure. If you force the cut, damage to the guide bar,
chain, or engine can result.
Release the throttle trigger as soon as the cut is
·
completed, allowing the engine to idle. If you run the saw at
full throttle without a cutting load, unnecessary wear can
occur to the chain, guide bar, and engine. It is
recommended that the engine not be operated for
longer than 30 seconds at full throttle.
To avoid losing control when cut is complete, do not put
·
pressure on saw at end of cut.
Stop the engine before setting the saw down after cutting.
·
FELLING A TREE
n PLANNING
WARNING! Check for broken or dead branches
which can fall while cutting causing serious
injury. Do not cut near buildings or electrical
wires if you do not know the direction of tree
fall, nor cut at night since you will not be able
to see well, nor during bad weather such as
rain, snow, or strong winds, etc. If the tree
makes contact with any utility line, the utility
company should be notified immediately.
1. Place the saw on firm ground.
2. Grip the rear handle with your right hand and the front
3. Apply full throttle by fully depressing the throttle trigger.
4. Activate the chain brake by turning your left wrist toward

WORKING TECHNIQUES

Carefully plan your sawing operation in advance.
Clear the work area. You need a clear area all around the tree
so you can have secure footing.
The chainsaw operator should keep on the uphill side of the
terrain as the tree is likely to roll or slide downhill after it is
felled.
Study the natural conditions that can cause the tree to fall in a
particular direction.
Natural conditions that can cause a tree to fall in a particular
direction include:
·
·
·
·
Look for decay and rot. If the trunk is rotted, it can snap and
fall toward the operator. Check for broken or dead branches
which can fall on you while cutting.
Make sure there is enough room for the tree to fall. Maintain a
distance of 2-1/2 tree lengths from the nearest person or
other objects. Engine noise can drown out a warning call.
Remove dirt, stones, loose bark, nails, staples, and wire from
the tree where cuts are to be made.
Plan a clear retreat path to the rear and diagonal to the line of
fall. Note the danger zone (1), retreat path (2), and felling
direction (3) in the following diagram.

contact the stump. When the tip of the bar hits the stump,
