WARNING!
Prolonged exposure to vibrations can cause
injuries and neurovascular disorders (also called “Raynaud's
syndrome” or “white hand”), especially to people suffering
from circulation disorders. The symptoms can effect the
hands, wrists, and fingers and manifest with loss of sensitivity,
numbness, itching, pain, and discoloring of or visible changes
to the skin. These effects can be worsened by low ambient
temperatures and/or by gripping the hand grips too tightly. If
the symptoms occur, the length of time the machine is used
must be reduced and a doctor consulted.
Checks During Work
•
Checking the chain tension
The chain tends to stretch gradually as you work, so you need
to check its tension frequently.
IMPORTANT!
During the first period of use (or after replacing
the chain), the chain tension must be checked more frequently
due to settling of the chain.
m
WARNING!
Never work with the chain loose, as it can
be hazardous if the chain slips out of the guide rails.
To adjust the chain tension, follow the instructions in
“Adjusting the Chain Tension” on page 11.
•
Checking the oil delivery
IMPORTANT! Never use the machine without lubrication! You
can check the oil level in the tank through the transparent
gauge. Make sure you fill up the oil tank every time you use
the machine. For best results, use only a good quality bar and
chain oil designed specifically for use with chain saws.
m
WARNING!
Make sure the bar and the chain are in
place when you check the oil delivery.
Start the motor and check if the chain oil is delivered as shown
below (Fig. 14).
Proper Cutting Stance
1. Weight should be balanced with both feet on solid
ground.
2. Keep your left arm and elbow locked in a "straight arm"
position to withstand any kickback force (Fig. 15).
3. Your body should always be to the left of the chain line.
Basic Cutting Procedures
1. Small trees up to 6 – 7 inches in diameters are usually cut
in a single cut. Notch cuts determine the direction the tree
will fall.
m
WARNING!
If the tree starts to fall in a wrong direction,
or if the saw got caught or hung up during the fall, leave the
saw and save yourself.
m
WARNING!
Periodically glance at the top of the tree
during the back-cut to ensure the tree is going to fall in the
desired direction.
2. Practice cutting a few small logs using the following
techniques to get the feel of using the saw before you
begin a major sawing operation.
3. Take the proper stance in front of the wood with the saw
turned off.
4. Squeeze the trigger and let the chain accelerate to full
speed before entering the cut.
5.
Hold the saw with both hands firmly. Always keep your
left hand on the front handle and your right hand on the
rear handle so that your body is to the left of the chain
line.
6. Keep the unit running the entire time you are cutting,
maintaining a steady speed.
