ASSEMBLY
CAUTION:
Always be sure that the tool is switched off and the
•
battery cartridge is removed 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 sleeve is in released position before inserting the
saw blade. If the blade clamp sleeve is in fixed position,
rotate the sleeve to the released position.

Insert the saw blade into the blade clamp as far as it will
go. The blade clamp sleeve rotates and the saw blade is
fixed. Make sure that the saw blade cannot be extracted
even though you try to pull it out.

If you do not insert the saw blade deep enough, the

saw blade may be ejected unexpectedly during
operation. This can be extremely dangerous.
To remove the saw blade, rotate the blade clamp sleeve
in the direction of the arrow fully. The saw blade is
removed and the blade clamp sleeve is fixed at the
released position.

fixed. In this case, rotate the blade clamp sleeve
fully, then make the sleeve fixed at the released
position.
OPERATION
001669
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.
Always use a suitable coolant (cutting oil) when
•
cutting metal. Failure to do so will cause premature
blade wear.
If the tool is operated continuously until the battery
•
cartridge has discharged, allow the tool to rest for
15 minutes before proceeding with a fresh battery.
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.
