– Provide for good ventilation of the work-
ing place.
– It is recommended to wear a P2 filter-
class respirator.
Observe the relevant regulations in your
country 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 7, 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
practical testing. The following recommenda-
tions apply:
– 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 8 can be swivelled by 45° to the
left or right for mitre cuts.
Loosen the screw 16 and lightly slide the base
plate 8 in the direction of the saw blade 10.
Bosch Power Tools
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 8 to
the desired position according to the scale 15.
Other mitre angles can be adjusted using a pro-
tractor.
Afterwards, push the base plate 8 to the stop to-
ward the mains cable.
Tighten the screw 16 again.
The splinter guard 14 can not be inserted for mi-
tre cuts.
Offsetting the Base Plate (see figure D)
For sawing close to edges, the base plate 8 can
be offset to the rear.
Completely unscrew the screw 16 using the Al-
len key 5.
Take the base plate 8 off and remount it offset
again so that the screw 16 can be screwed into
the rear bolt hole 18.
Push the base plate 8 toward the positioning
pin/mark 17 until it engages. Now, tighten the
screw 16 again.
Sawing with the base plate 8 offset is possible
only with a mitre angle of 0°. In addition, the
parallel guide with circle cutter 21 (accessory)
as well as the splinter guard 14 may not be used.
Sawdust Blower Device
With the air jet of the sawdust blower device 6,
the cutting line can be kept free of dust and
chips.
Sawdust-blower setting I:
Low blow effect for sawing in metal and
operation with coolant/lubricant.
Sawdust-blower setting II:
Medium blow effect for sawing materials
with low chip removal rate, e. g., hard-
wood.
Sawdust-blower setting III:
Large blow effect for sawing materials
with high chip removal rate, e.g., soft-
wood, plastic, etc.
