Manual instruction | Gasoline chain saw
EN
The service life of the chain depends upon the
sufficient lubrication and proper tension.
In order to check the tension level of the saw chain
(1), pull it slightly aside from the center line of the
guide bar (2) and then release the
chain. If the saw chain (1) is stretched
properly, it can be pulled aside from
the guide bar (2) by a maximum 3
mm; moreover, it must return to its
original position under its own
elasticity.
Adjust the tension of the saw chain (1) as follows:
loosen the nuts (19) with the help of the multi- •
purpose wrench (20);
adjust the tension of the saw chain I with •
the tightening screw (24), by turning it with a
screwdriver on the multi-purpose wrench (18). To
increase the tension of the saw chain (1) turn the
tightening screw (24) clockwise. To decrease the
tension of the saw chain (1) turn the tightening
screw (24) counterclockwise.
tighten the nuts (19) with the help of the multi- •
purpose wrench (18) without applying the excessive
force, in order not to damage the threaded joint.
Initial operating
Prior to the start of the operation check
the tension of the saw chain (1), as well
as the oil level and fuel level in the
tanks.
Oil level check
Prior to each use of the machine, as well as after
every 10 minutes of operation it is necessary to
perform a check of oil level in the oil tank.
Place the machine on its side on flat ground. •
Clean the surface around the plug (15) and •
unscrew it.
Insert the clean rod into the mouth of the oil •
tank: if the oil level doesn’t reach 2/3 of the rod’s
length add oil into the tank.
Replace the plug (15). •
In order to avoid damage to the machine, use the
oil of recommended grade. Any use of re-filtered
or waste oil is prohibited; any damage that might
emerge in such case shall not be subject to the
warranty repair.
Fuel level check
Prior to each use of the machine it is necessary to
perform a check of the fuel level in the fuel tank.
Place the machine on its side on flat ground. •
Clean the surface around the plug (14) and •
unscrew it.
Insert the clean rod into the fuel tank, if the fuel •
level doesn’t reach 2/3 of the rod’s length, add fuel.
Replace the plug (14). •
Petrol-oil mixture is used as the fuel for the two-
stroke engine of the machine; see mixture ratio in
the technical data table. The use of any other fuel
mixtures or pure petrol for filling up the machine
is prohibited, it may damage the engine and void
your right for warranty repair.
Switching On/Off
Switching on
Set the switch (12) to “On”. •
Pull out the throttle lever (13) completely. •
Lay the machine down and, while holding the •
lower portion of the rear handle (9) with the foot,
pull smoothly the handle of the starter cord (8)
smoothly until you feel resistance.
Pull on the starter cord (8). Repeat until the motor •
starts. As soon as the engine runs smoothly, return
the throttle lever (13) back to the middle position.
Press the accelerator (16) halfway. •
The unlocking button (17) will lock the •
accelerator (16).
