PLUNGE CUTTING (See Fig. C1, C2)
Warning: The plunge cutting procedure
is only suitable for treating soft
materials such as wood, plaster board or
similar! Do not work metal materials with the
plunge cutting procedure!
Use only short saw blades for plunge cutting.
Place the machine with the edge of the pivoting
blade foot (2) onto the workpiece and switch on.
For power tools with stroke speed control, set
the maximum stroke speed. Press the power tool
firmly against the workpiece and allow the saw
blade to slowly plunge into the workpiece.
As soon as the pivoting blade foot (2) fully lays
on the surface of the workpiece, continue sawing
alongside the desired cutting line. For certain
work, the saw blade (1) can also be inserted
turned through by 180° and the sabre saw can
be guided accordingly in a reversed manner.

Flush cutting (See Fig. D1, D2)
Warning: Pay attention that the saw
blade always extends beyond the
diameter of the material being worked. There
is danger of kickback.
It is possible to make cuts extremely close to
floors, walls and other difficult areas. Insert the
blade shank into the blade clamp with the blade
teeth facing up (opposite to normal working
position). This will make cuts closer to the work
surface. Using special flexible blades insert the
blade into the blade clamp with the blade teeth
facing down (normal working position). It will
allow flush pipe cutting.

WOOD CUTTING
For easier control use low speed to start cutting,
then increase to the correct speed.
METAL CUTTING
This saw has different metal cutting capacities
depending upon the type of blade being used
and metal being cut.
Use a finer blade for ferrous metals and a coarse
blade for non-ferrous metals.
When cutting thin gauge sheet metals, ALWAYS
clamp wood on both sides of the sheet. This will
give you a clean cut without excess vibration or
tearing of the metal.
DO NOT force the cutting blade. Forcing the
blade will reduce blade life and cause the blade
to break.
NOTE: We recommend that you spread a thin
film of oil or other coolant along the line of cut
ahead of the saw. This will allow easier operation
and help extend blade life. When cutting
aluminum, use kerosene.
