TRANSPORTING THE CHAINSAW
Before transporting the chainsaw, always remove
the plug from the power socket and slide the chain
guard over the rail and chain. If several cuts are to be
performed with the chainsaw, the chainsaw must be
switched off between cuts.
BEFORE STARTING UP
The voltage and current supply must comply with the
ratings on the type plate. Before commencing work,
always check that the chainsaw works properly and
is safe to operate. Check also that the chain lubrica-
tion and the oil gauge are in good working order (See
fig.4). When the oil lever is approx. 5mm from the
bottom mark, you must top up with oil. When the oil
level is above this mark you can begin work.
Attach the power cord to the wire holder (18) by loop-
ing it as shown in (See fig.6). This will prevent the cord
from coming unplugged.
Switch on the chainsaw and hold it above the ground.
Do not allow the chainsaw to touch the ground. For
safety reasons it is best to keep a clearance of at least
20 cm. If you now see growing traces of oil, the chain
lubrication system is working correctly. If there are
no traces of oil at all, try cleaning the oil outlet (See
fig.2,C) the upper chain tensioning borehole (E) and
the oil duct , or contact your local Osaki agent (Be sure
to read the section “Filling up with chain oil and chain
lubrication” on this point). Check the chain tension
and retention if necessary (see the section “Tension-
ing the saw chain” on this point). Make sure the chain
brake is working properly (see the section “Releasing
the chain brake”.
ASSEMBLING THE GUIDE BAR AND SAW CHAIN
(See fig.1.2.3)
The chainsaw must be unplugged. Important: The
front finger guard (4) must always be in the top (verti-
cal) position (See fig.5)
The guide bar and saw chain are supplied separately.
To assemble, first unscrew the lock nut (6) and remove
the guide bar cover (7). The chain tensioning bolt
(21) must be in the centre of the guide. If necessary,
adjust the chain tensioning bolt with the screw (17). To
prevent injury on the sharp cutting edges, always wear
gloves when assembling, tensioning and checking the
chain. Before assembling the guide bar with the saw
chain, check the cutting direction of the teeth! The run-
ning direction is marked with an arrow on the cover (7)
(See fig.3, G.) To determine the direction of cut, it may
be necessary to turn over the saw chain (5).
Hold the guide bar (8) vertically with the tip pointing
upwards and put on the saw chain (5), beginning at
the tip of the bar.
THEN ASSEMBLE THE GUIDE BAR WITH THE SAW
CHAIN AS FOLLOWS: (See fig.3)
Place the guide bar with the saw chain on the guide
bolt (20) and chain tensioning bolt (21).
Place the saw chain round the chain wheel (19) and
make sure it is correctly mounted (See fig.1,A)
Place the cover (7) on top and tighten gently with the
lock nut (6) the supplied wrench. Now the saw chain
has to be correctly tensioned.
TENSIONING THE SAW CHAIN
Always pull the plug out of the power socket before
doing any work on the chainsaw.
Wear safety gloves!
Make sure the saw chain (5) is inside the guide groove
of the guide bar (8) (See fig.1 a). Using the supplied
hex key, turn the chain until it is correctly tensioned.
While the bolt (21) is being tightened, the guide bar
must then be pushed upwards. Check the chain ten-
sion again (See fig.3) Do not tension the chain too
tightly. When cold, it should be possible to lift the
chain in the middle of the guide bar approx. 5mm.
Tighten the lock nut (6) securely.
When warm, the saw chain will expand and slacken
and there is a danger of it jumping off the rail alto-
gether. Re-tension if necessary. If the saw chain is re-
tensioned when hot, it must be loosened again when
the sawing work has been completed. Otherwise, the
contraction which takes place as the chain cools will
result in excessively high tension.
A new saw chain requires a running-in period of ap-
prox. 5 minutes. Chain lubrication is very important
at this stage. After running in, check chain tension and
re-tension if necessary.
FILLING UP WITH CHAIN OIL (See fig.4)
To prevent dirt getting inside the tank, clean the oil
tank cap (15) before opening. Check the contents of
the oil tank during sawing work by checking the oil
gauge (16). Close the oil tank cap tightly and wipe
away any spills.
