The SSU 200 EB sword saw cutting tool set's
chain links are 3/8" apart, and their thickness is
1.3 mm. Other tool sets can be used only with ex-
plicit approval from the manufacturer. The spac-
ing of the chain links must be identical to the
spacing of the chain sprocket and to the spacing
of the guide bar pulley.
The complete cutting tool set consists of:
a) chain sprocket [8-3]
b) guide bar [2-4]
c) chain [2-3]
The cutting tool set's service life depends mainly
on lubrication and chain tension. For this reason
the chain tension must be checked and adjusted
both before and during work.
11.1

Chain tension

With the cover of the chain sprocket [2-1] slightly
released, rotate the chain adjustment wheel [2-
9] in the direction of the + arrow until the bottom
part of the chain hugs the guide bar of the chain,
as shown in Fig. [10]. Then tighten the chain
sprocket cover fi rmly [2-1] by turning the fasten-
ing wheel [2-2] clockwise. Check the chain for
correct tension by slightly pulling the bottom part
of the chain, as shown in Fig. [10]. Once released,
the chain must return to the initial position and
closely cling to the guide bar.
Chains that have been tightened while hot must
be released when the work is fi nished. When the
tightened chain has cooled, high tension occurs
due to its shrinkage, which might cause damage
to the machine!

11.2 Maintaining and sharpening the chain
The chain must be sharpened if the sawdust is
too fi ne, see Fig. [11].
11.3 Lubricating the chain
The oil reservoir capacity is 240 ml. To avoid heavy
wear, the chain and its guide bar must be continu-
ously lubricated during operation of the machine.
Lubrication is provided by an oil feed pump, which
delivers an optimal amount of oil into the lubrica-
tion groove in the guide bar. It is very important to
check the oil reservoir level and the chain lubrica-
tion function before you start working. If the oil
level [1-8] drops to the bottom indicator on the
oil gauge, the oil must be replenished.
Recommendation:
Use only the oil intended for chain saw lubrica-
tion. The use of used oil or any oil not intended
for chain lubrication is prohibited. Before opening
the oil reservoir, carefully clean the area around
the oil cap! Sawdust and chips that could get into
the reservoir may block the oil channels, which
can lead to a serious breakdown in chain lubri-
cation! Due to their composition, biodegradable
oils for chain lubrication have reduced lubricating
ability, and a prolonged break in the operation of
the machine might make the inner lubrication
channels sticky. Therefore follow manufacturer
recommendations!
11.4 Maintaining the guide bar
The one-sided wear of the guide bar can be prevent-
ed by turning it after each time the chain is sharp-
ened. Worn-out outer guide surfaces (Fig. [9b])
are considered a normal operational wear. Use a
fi ne, fl at fi le to remove burred edges. The inner
guide surfaces (Fig. [9a]) become worn due to
insuffi cient lubrication, incorrect chain lubrica-
tion, or improper working procedure. The guide
bar must be replaced!
Under no circumstances can the chain links touch
the bottom of the guide bar channel. If the chain
touches the bottom of the channel, the guide bar
is so worn that it must be replaced. The lubrica-
tion ports and the guide bar channel (groove) must
be clean at all times.
11.5 Maintaining the chain sprocket
Most diffi culties with the chain are caused by in-
correct chain tightening or late replacement of the
chain sprocket. A worn chain sprocket can very
quickly damage the good portion of an expensive
cutting tool assembly. Don't be stingy about re-
placing the chain sprocket! It is recommended
