– Turn the rotating handle 1 approx. three turns
in the direction of the arrow.
– Insert the saw blade 9 lateral to the cutting di-
rection into the stroke rod 11.
– Turn the saw blade 9 so that the toothing fac-
es toward the cutting direction. Pull the saw
blade 9 a little downward until it engages.
– Turn the rotating handle 1 in the direction of
the arrow until a click can be heard.
– Push up the orange pushbutton at the rotata-
ble top handle 1 again to the starting position.
Check the tight seating of the saw blade. A
loose saw blade can fall out and lead to inju-
ries.
Splinter Guard (see figure B)
Before any work on the machine itself, pull
the mains plug.
The splinter guard 12 (accessory) can prevent
fraying of the surface while sawing wood. The
splinter guard can only be used for certain saw
blade types and only for cutting angles of 0°.
When sawing with the splinter guard, the base
plate 7 must not be moved back for cuts that are
close to the edge.
Press the splinter guard 12 from the bottom into
the base plate 7.
Dust/Chip Extraction
Dusts from materials such as lead-containing
coatings, some wood types, minerals and
metal can be harmful to one's health. Touch-
ing or breathing-in the dusts can cause aller-
gic reactions and/or lead to respiratory infec-
tions of the user or bystanders.
Certain dusts, such as oak or beech dust, are
considered as carcinogenic, especially in con-
nection with wood-treatment additives (chro-
mate, wood preservative). Materials contain-
ing asbestos may only be worked by
specialists.
– Provide for good ventilation of the working
place.
– It is recommended to wear a P2 filter-class
respirator.
Observe the relevant regulations in your coun-
try for the materials to be worked.

Operation
Operating Modes
Before any work on the machine itself, pull
the mains plug.
Orbital Action Settings
The four orbital action settings allow for optimal
adaptation of cutting speed, cutting capacity and
cutting pattern to the material being sawed.
The orbital action can be adjusted with the ad-
justing lever 6, even during operation.
Setting 0
No orbital action
Setting I Small orbital action
Setting II
Medium orbital action
Setting III
Large orbital action
The optimal orbital action setting for the respec-
tive application can be determined through prac-
tical testing. The following recommendations ap-
ply:
– Select a lower orbital action setting (or switch
it off) for a finer and cleaner cutting edge.
– For thin materials such as sheet metal, switch
the orbital action off.
– For hard materials such as steel, work with
low orbital action.
– For soft materials and when sawing in the di-
rection of the grain, work with maximum or-
bital action.
Adjusting the Cutting Angle (see figure C)
The base plate 7 can be swivelled by 45° to the
left or right for mitre cuts.
– Loosen the screw 14 and lightly slide the base
plate 7 in the direction of the saw blade 9.
– For adjustment of precise mitre angles, the
base plate has adjustment notches on the left
and right at 0° and 45°. Swivel the base plate
7 to the desired position according to the
scale 13. Other mitre angles can be adjusted
using a protractor.
– Afterwards, push the base plate 7 to the stop
toward the mains cable.
– Tighten the screw 14 again.
The splinter guard 12 can not be inserted for mi-
tre cuts.
