Recommended fuels
Some conventional gasolines are being blended with
oxygenates such as alcohol or an ether compound to
meet clean air standards. Your engine is designed to
operate satisfactorily on any gasoline intended for
automotive use including oxygenated gasolines. It is
recommended to use unleaded petrol as fuel.
Lubrication of chain and chain bar
Whenever you refill the fuel tank with petrol you must
also top up the level of chain oil in the chain oil tank. It
is recommended to use standard chain oil.
Engine pre-start checks
Danger! Never start or operate the saw unless
the bar and chain are properly installed.
1. Fill the fuel tank (A) with correct fuel mixture
(Fig. 8).
2. Fill the oil tank (B) with chain oil (Fig. 8).
3. Be certain the chain brake is disengaged (C)
before starting unit (Fig. 8).
Once you have filled the chain and oil tank,
tighten the tank cover securely by hand. Do not
use any tools to do so.

6. Operation

Before you use the equipment, check it for damage. If
you discover any damage, do not use it. The
equipment may be started only when the chain brake
is engaged. The chain brake is engaged when the
brake lever is pressed forward and the mechanism
(Fig. 7B/Item A) is visible.

6.1 Starting the engine

1. Set the On/Off switch (A) to "On (I)" to start the
machine (Fig. 9A).
2. Pull out the throttle lever (B) (Fig. 9B) until it
locks.
3. Push the primer bulb (C) 10 times (Fig. 9C).
4. Place saw on a firm, flat surface. Hold saw firmly
as shown. Pull starter rapidly 2 times. Beware of
moving chain! (Fig.9D)
5. Push in the throttle lever (B) as far as it will go
(Fig. 9B).
6. Hold saw firmly and pull starter rapidly 4 times.
Engine should start (Fig. 9D).
7. Let the engine run for 10 seconds to warm up.
Press the throttle lever (D) briefly, the engine will
go to "idling" speed (Fig. 9E).
If engine failed to start, repeat these instructions.
Notice: Always pull the starter cable slowly until you
feel the initial resistance before you then pull it quickly
to start the engine. Do not allow the starter cable to
whip back of its own accord.

6.2 Restarting a warm engine

6.4 General cutting instructions

Danger!
Felling trees is prohibited without the necessary
training!
Felling
n
Felling is the term for cutting down a tree. Small
trees up to 6-7 inches (15-18cm) in diameter are
usually cut in a single cut. Larger trees require
notch cuts. Notch cuts determine the direction the
tree will fall.
A retreat path (A) should be planned and cleared
n
as necessary before cuts are started. The retreat
path should extend back and diagonally to the
rear of the expected line of fall, as illustrated in
Fig. 11.
If felling a tree on sloping ground, the chain saw
n
operator should keep on the uphill side of the
terrain, as the tree is likely to roll or slide downhill
after it is felled.
Direction of fall (B) is controlled by the notching
n
cut. Before any cuts are made, consider the
location of larger branches and natural lean of the
tree to determine the way the tree will fall (Fig.
11).
Do not cut down a tree during high or changing
n
winds or if there is a danger to property. Consult a
tree professional. Do not cut down a tree if there
is a danger of striking utility wires; notify the utility
company before making any cuts.
General guidelines for felling trees (Fig. 12)
n
Normally felling consists of 2 main cutting
operations, notching (C) and making the felling
cut (D). Start making the upper notch cut (C) on
the side of the tree facing the felling direction (E).
