2. Use a brush or shake the air filter clean. Use
detergent and water to clean it fully.
Note: An air filter that is used for a long time can not
be fully cleaned. Replace the air filter regularly and
always replace a defective air filter.
3. Attach the air filter and make sure that the air filter
seals tightly against the filter holder.
Note: Because of different work conditions, weather or
season, your product can be used with different types of
air filter. Speak to your servicing dealer for more
information.
To do a check of the spark plug
CAUTION: Use the recommended spark
plug. Refer to
Technical data on page 34
.
An incorrect spark plug can cause damage
to the product.
1. If the product is not easy to start or to operate or if
the product operates incorrectly at idle speed,
examine the spark plug for unwanted materials. To
decrease the risk of unwanted material on the spark
plug electrodes, do these steps:
a)
make sure that the idle speed is correctly
adjusted.
b) make sure that the fuel mixture is correct.
c) make sure that the air filter is clean.
2. Clean the spark plug if it is dirty.
3. Make sure that the electrode gap is correct. Refer to,
Technical data on page 34
.
4. Replace the spark plug monthly or more frequently if
necessary.
To calculate the felling direction
1.
Examine in which direction it is necessary for the
tree to fall. The goal is to fell it in a position where
you can limb and cut the trunk easily. It is also
important that you are stable on your feet and can
move about safely.
WARNING: If it is dangerous or not
possible to fell the tree in its natural
direction, fell the tree in a different
direction.
2. Examine the natural fall direction of the tree. For
example the tilt and bend of the tree, wind direction,
the location of the branches and weight of snow.
3.
Examine if there are obstacles, for example other
trees, power lines, roads and/or buildings around.
4. Look for signs of damage and rot in the stem.
WARNING: Rot in the stem can mean a
risk that the tree falls before you
complete the cutting.
5. Make sure the tree has no damaged or dead
branches that can break off and hit you during
felling.
6.
Do not let the tree fall onto a different standing tree.
It is dangerous to remove a caught tree and there is
a high accident risk. Refer to
To free a trapped tree
on page 19
.
WARNING: During critical felling
operations, lift your hearing protection
immediately when the sawing is
complete. It is important that you hear
sounds and warning signals.
To sharpen the saw chain
Information about the guide bar and saw chain
WARNING: Use protective gloves when you
use or do maintenance on the saw chain. A
saw chain that does not move can also
cause injuries.
Replace a worn or damaged guide bar or saw chain with
the guide bar and saw chain combination recommended
by Husqvarna
. This is necessary to keep the safety
