ASSEMBLY
CAUTION:
•
Always be sure that the tool is switched off and
unplugged before carrying out any work on the
tool.
Installing or removing the saw blade
CAUTION:
•
Always clean out all chips or foreign matter
adhering to the blade, blade clamp and/or slider.
Failure to do so may cause insufficient tightening
of the blade, resulting in a serious injury.
To install the saw blade, always make sure that the
blade clamp lever is in released position
on the
insulation cover before inserting the saw blade. If the
blade clamp lever is in fixed position, rotate the blade
clamp lever in the direction of the arrow so that it can be
locked at the released positon .
Fig.4
Insert the saw blade into the blade clamp as far as it will
go. The blade clamp lever rotates and the saw blade is
fixed. Make sure that the saw blade cannot be extracted
even though you try to pull it out.
Fig.5
NOTE:
•
If you do not insert the saw blade deep enough, the
saw blade may be ejected unexpectedly during
operation. This can be extremely dangerous.
If the lever is positioned inside the tool, switch on the
tool just a second to let the blade out as shown in the
figure.
Switch off and unplug the tool from the mains.
To remove the saw blade, rotate the blade clamp lever in
the direction of the arrow fully. The saw blade is
removed and the blade clamp lever is fixed at the
released position .
Fig.6
NOTE:
•
Keep hands and fingers away from the lever during
the switching operation. Failure to do so may
cause personal injuries.
•
If you remove the saw blade without rotating the
blade clamp lever fully, the lever may not be locked
in the released position . In this case, rotate the
blade clamp lever fully again, then make sure that
the blade clamp lever locked at the released
position .
OPERATION
CAUTION:
•
Always press the shoe firmly against the workpiece
during operation. If the shoe is held away from the
workpiece during operation, strong vibration and/or
twisting will be produced, causing the blade to
snap dangerously.
•
Always wear gloves to protect your hands from hot
flying chips when cutting metal.
•
Be sure to always wear suitable eye protection
which conforms with current national standards.
•
Always use a suitable coolant (cutting oil) when
cutting metal. Failure to do so will cause premature
blade wear.
Press the shoe firmly against the workpiece. Do not
allow the tool to bounce. Bring the blade into light
contact with the workpiece. First, make a pilot groove
using a slower speed. Then use a faster speed to
continue cutting.

•
Always be sure that the tool is switched off and
unplugged before attempting to perform inspection
or maintenance.

Take out the worn carbon brushes, insert the new ones
