9. Assembly
Assembling the guide bar and saw chain(Fig1,2,3)
The chainsaw must be unplugged.
Important:The front finger guard (3) must always
be in the top (vertical) position (Fig. 5).
The guide bar and saw chain are supplied
separately. To assemble, first unscrew the lock knob
(5) and remove the guide bar cover (6). The chain
tensioning bolt (18) must be in the center of the
guide. If necessary, adjust the chain tensioning bolt
with the screw (16). 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
running direction is marked with an arrow on the
Fig 1 (A). To determine the direction of cut, it may
be necessary to turn over the saw chain (4). Hold
the guide bar (7) vertically with the tip pointing
upwards and put on the saw chain (4) beginning at
the tip of the bar. Then assemble the guide bar with
the saw chain as follows: Place the guide bar with
the saw chain on the guide bolt (17) and chain
tensioning bolt (18). Place the saw chain round the
chain wheel (16) and make sure it is correctly
mounted (see Fig.3). Place the guide bar cover (6)
on top and tighten gently with the lock knob (5) by
hand. 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 (4) is inside the guide groove
of the guide bar (7) (Fig.1 A)!
Turn the lock knob (5) clockwise by hand until the saw
chain is correctly tensioned. 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 5 mm.
Tighten the guide bar cover (6) securely.
When warm, the saw chain will expand and slacken
and there is a danger of it jumping off the rail
altogether. 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 would
result in excessively high tension. A new saw chain
requires a running-in period of approx .5 minutes.
Chain lubrication is very important at this stage. After
running in, check chain tension and re-tension if
necessary.
10.Operation instructions
Filling in chain oil (Fig 4)
To prevent dirt getting inside the tank, clean the oil tank
cap (21) before opening. Check the contents of the oil
tank during sawing work by checking the oil gauge
(15). Close the oil tank cap tightly and wipe away any
spills.
Securing the extension lead (Fig 6)
Only use extension leads suitable for outdoor use. The
cross section of the cable (max. length of extension
cord: 75m) must be at least 1,5 mm2. secure the
chainsaw flex to the extension lead by inserting the
extension lead into the strain relief gap of the housing.
Extension leads longer than 30 m will reduce the
performance of the chainsaw.
Chain lubrication
To prevent excessive wear, the saw chain and guide
bar must be evenly lubricated during operation.
Lubrication is automatic. Never work without chain
lubrication. If the chain runs dry, the entire cutting
apparatus will quickly become severely damaged. It is
therefore important to check both chain lubrication and
the oil gauge every use (Fig. 4).
Never use the saw when the oil level is below the “Min.”
mark.
Min.: When only approx. 5 mm of oil is visible at
the lower rim of the oil gauge (15), you must top up
with oil.
Max.: Top up with oil until the window is full.
