UNPACKING
Caution! This packaging contains sharp objects. Take
care when unpacking. Remove the machine, together
with the accessories supplied, from the packaging.
Check carefully to ensure that the machine is in good
condition and account for all the accessories listed in

ASSEMBLY
This chainsaw uses a 4 stroke engine and does not
require the mixing of oil with the fuel.
The chainsaw is fitted with ONE lubrication oil tank (15)
and ONE chain oil tank (17) and a SEPARATE fuel tank
(10).
ATTACHING THE CHAIN BAR & CHAIN TO THE ENGINE
UNIT
CAUTION: Do not start the engine until the saw is fully
assembled.
CAUTION: Wear protective gloves at all times when
handling the chain.
REMOVE THE SIDE COVER (FIG.2)
Make sure the chain brake lever / front hand guard (3)
is pulled back into the DISENGAGED position.
Remove the bar mounting nuts (11) with the spark plug
spanner (19).
Pull the whole side cover (A) from the engine.
FIT THE CHAIN BAR (FIG.2 & 3)
To ensure that the bar and the chain are supplied with
oil, USE ONLY THE ORIGINAL BAR.
The oiling hole (C) must be kept clear of dirt and any
build-up of residue.
Make sure the chain brake lever / front hand guard (3)
is pulled back into the DISENGAGED position.
Fit the open end of the chain bar (1) over the bar pins
(D).
INSTALLING THE SAW CHAIN (FIG.2,3 & 4)
Spread the saw chain (2) out in a loop with the cutting
edges pointing CLOCKWISE around the loop.
Slip the saw chain (2) around the sprocket behind the
clutch as shown in figure 3. Make sure the links fit
between the sprocket teeth.
Guide the drive links into the groove and around the end
of the chain bar (1).
NOTE: The saw chain may droop slightly on the lower
part of bar. This is normal.
Pull the chain bar (1) forward until the saw chain (2) is
closely seated. Make sure that all the drive links are in
the groove of the chain bar (1).
Align the projecting pin (F) at the inner side of the side
cover (A) such that the fits into the hole of the chain bar
(E).
Turn the bar fastening pin (B) clockwise with the spark
plug spanner (19). The saw chain (2) is not allowed to
slip off the chain bar (1) when you do this. Only loosely
tighten the bar fastening pin (B) at this stage and then
follow the instructions for adjusting the chain tension
as described in the section ADJUSTING THE CHAIN
TENSION.

ADJUSTING THE CHAIN TENSION

The correct tension of the saw chain is extremely
important and must be checked before starting and
periodically during all sawing work. If you take time to
adjust the saw chain correctly, you will be able to make
better cuts and the life of the chain will be prolonged.
Hold the tip of the chain bar (1) upwards and turn the
bar fastening pin (Fig. 2/ pos. B) with the spark plug
spanner (19) in a CLOCKWISE DIRECTION in order to
increase the chain tension. If you turn the bar fastening
pin (Fig. 2/pos. B) in an ANTI-CLOCKWISE DIRECTION, the
chain tension will be reduced. Check that the chain is
seated around the entire chain bar (Fig. 5/pos. X3).
