specifically trained to do so.
▪ All chain saw service, other than the items listed in the user
manual safety and maintenance instructions, should be performed
by competent chain saw service personnel.
▪ When transporting your chain saw, use the appropriate guide bar
scabbard.
▪ DO NOT operate your chain saw near or around flammable
liquids or gases whether in or out of doors. An explosion and/or
fire may result.
▪ Do not fill fuel tank, oil tank or lubricate when the engine is
running.
▪ USE THE RIGHT TOOL: Cut wood only. Do not use the chain
saw for purposes for which it was not intended. For example, do
not use the chain saw for cutting plastic, masonry, or non-building
materials.
▪ The first time user should have practical instruction in the use of
chainsaw and the protective equipment from an experienced
operator.
▪ Do not attempt to hold the saw with one hand only. You cannot
control reactive forces and you may lose control of the saw, which
can result in the skating or bouncing of the bar and chain along
the limb or log.
▪ Never run the chainsaw indoors. Your chainsaw produces
poisonous exhaust as soon as the combustible engine is started,
which may be colourless and odourless. To use this product can
generate dust, mists and fumes containing chemicals known to
cause reproductive harm. Be aware of harmful dust, mist (such as with thumbs and fingers encircling the chain saw
handles. A firm grip will help you reduce kickback and
maintain cont
rol of the saw. Don’t let go.
▪ Make sure that the area in which you are cutting is free
from obstructions. Do not let the nose of the guide bar
contact a log, branch, or any other obstruction which
could be hit while you are operating the saw.
▪ Cut at high engine speeds.
▪ Do not overreach or cut above shoulder height.
▪ Follow manufacturer’s sharpening and maintenance
instructions for the saw chain.
▪ Only use replacement bars and chains specified by the
manufacturer or the equivalent.
NOTE: Low-kickback saw chain is chain that
has met the kickback performance.
WARNING: Kickback can lead to dangerous
loss of control of the chain saw and result in serious
or fatal injury to the saw operator or to anyone
standing close by. Always be alert. Rotational
kickback and pinch-kickback are major chain saw
operational dangers and the leading cause of most
accidents.
SAFETY WARNINGS GASOLINE
WARNING: Use extra care in handling fuels. They are
flammable and the vapours are explosive.
The following points must be observed:
▪ Use only an approved container.
▪ Never remove the fuel cap or add fuel with the power source
running. Allow engine exhaust components to cool before
refuelling.
▪ Do not smoke.
▪ Never refuel the machine indoors.
▪ Never store the machine or fuel containers inside,
where is an open flame, such as a water heater.
▪ If fuel is spilled, do not attempt to start the power
source, but move the machine away from the area of
spillage before starting.
▪ Always replace and securely tighten the fuel cap after
refuelling.
▪ If the tank is drained, this should be done outdoors.
ASSEMBLY
Danger: Do not start the engine until the saw is fully assembled.
Caution: Wear protective gloves at all times when handling the
chain.
Installing the guide rail and saw chain (Fig. 2A-2G)
1. Disengage the chain brake by pushing the front hand guard (6)
towards the front handle (7). (Fig. 2A)
2. Remove the chain bar cover (A) by loosening the nut (19) (Fig.
2B)
3. Place the guide rail (2) into the mounting on the chainsaw (Fig.
2C).
4. Place the chain (3) around the drive wheel (C) (Fig. 2E). Check
that the direction of rotation of the chain (3) is correct. The cutter
links (B) must be aligned as shown in Fig. 2D.
5. Place the chain around the chain bar. (Fig.2E)
6. The chain drive links (3) must slide fully into the groove which
runs around the cutter bar (D) and also between the teeth on the
drive wheel (C). (Fig. 2E)
7. Turn the chain tensioning screw (20) counterclockwise until the
bolt (E) is at the end of its travel. (Fig. 2B/2F)
8. Install the bar cover (A).
Important! The bolt (E) on the chain tensioning mechanism must
snap into place in the hole (G) in the guide rail. (Fig. 2G).
To ensure that happens, slide the guide rail (2) forwards and
backwards slightly when you mount the bar cover (A). Hand
tighten the nut (19).
Adjusting the chain tension (3A/3B)
Before adjusting the chain tension, make sure that the engine is
switched off .
1. Push the tip of the guide rail (2) upwards slightly and adjust the
chain tension using the chain tensioning screw (20).
(Fig. 3A) The chain is set to the optimal tension when
the chain (3) on the underside at the middle of the guide
rail (2) is as shown in Fig. 3B.
2. Tighten the nut (19) while applying slight pressure to
the tip of the bar.
3. Carry out a functional check. Pull the chain (3) by
hand once all the way around the guide rail (2). If the
chain (3) is hard to pull around the guide rail (2) or if it
jams, the tension is too tight.
If that is the case, make the following slight adjustment:
1. Loosen the nut (19) and hand tighten it again.
2. Reduce the chain tension by turning the chain
tensioning screw (20) counterclockwise. Only make
small adjustments at a time and always pull the chain (3)
backwards and forwards on the guide rail (2) to see if the
chain moves smoothly (3) but still fi ts tightly.
Note: If the chain (3) is too loose, turn the chain
tensioning screw (20) clockwise.
3. If the chain tension is adjusted to the optimal setting,
tighten the nut (19) while applying slight pressure to the
tip of the bar.
A new saw chain will stretch, so it is important to
readjust the chain at short intervals (around 5 cuts)
when you fi rst start using it. The intervals get longer
as operating time increases.
Note:
If the saw chain (3) is TOO LOOSE or TOO
TAUT, the drive wheel, chain bar, chain and crank shaft
bearing will suff er premature wear. Fig. 3B shows the
correct tension A (when cold) and tension B (when
warm). Fig. C shows a chain that is too loose.
