This allows clean cuts by accurately guiding the
machine along a marked edge. Hard anodising
of the guide bar makes moving the machine even
easier, thus reducing the necessary slide force,
and at the same time makes for a better work-
ing procedure. The saw runner’s side clearance
can be adjusted using the distance screws in the
auxiliary handles
[6-1] .
10.2 Assembling the guide rail
The guide rail [7-1] is assembled using special
clamps FSZ 300 [7-2] or FS-RAPID/L [7-5] to be
inserted into the guide grooves designed for this
particular purpose (Fig. [7a]). This allows a secure
hold on uneven surfaces. Anti-slip strips are at-
tached to the bottom of the guide bar, providing
safe placement and preventing scratches to the
material surface.
CAUTION
If you cut with a tilted saw, the tool and the
clamp bolt with the gripper or with FS-RAPID/L
may collide.

Tilt the saw at such an angle only to avoid
collision of the chain with the clamp.
10.3 Assembling the angle guide (FS-AG-2)
The combination of the guide rail and the continu-
ously adjustable angle unit
[7-3] allows accurate
angular cuts, e. g., for matching fi ts. Mount the
angle unit as shown in Fig. [7b]. You can set the
required cutting angle on the bevel indicator.
10.4 Assembling the connector
(FSV)
Depending on the use and size of the work piece,
multiple guide rails can be jointed together us-
ing a connecting spring
[7-4] (Fig. [7c]). For fi rm
connection of multiple guide rails the links can be
affi xed using the screws in the correspondingly
threaded openings.
10.5 Assembling the quick clamp (FS-
RAPID/L)
The guide rail can be mounted quickly using this
device
[7-5] slipped into the bottom groove. A fi rm
mount is achieved by pressing the trigger, and re-
lease is achieved by pressing the stopping button.
CAUTION
If you cut with the saw at an incline, the tool and
the quick clamp handle may collide.

The handle of the quick clamp must be turned
to the left towards the material after tighten-
ing, thus preventing the collision even at the
maximum tilt of 60°.
11 Service and maintenance

The IS 330 EB insulation 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.
