Installing or removing the recipro
saw blade
CAUTION:
Always clean out all chips or for-
eign matter adhering to the blade and around the
blade clamp. Failure to do so may cause insufficient
tightening of the blade, resulting in a serious injury.
To install the recipro saw blade, always make sure that
the blade clamp lever (part of the blade clamp sleeve)
is in released position
inserting the recipro 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.5: 1. Blade clamp lever 2. Released position
3. Fixed position
Insert the recipro saw blade into the blade clamp as far
as it will go. The blade clamp sleeve rotates and fixes
the recipro saw blade. Make sure that the recipro saw
blade cannot be extracted even though you try to pull
it out.

CAUTION:
If you do not insert the recipro saw
blade deep enough, the recipro saw blade may be
ejected unexpectedly during operation. This can
be extremely dangerous.
To remove the recipro saw blade, rotate the blade
clamp lever in the direction of the arrow fully. The reci-
pro saw blade is removed and the blade clamp lever is
fixed at the released position

CAUTION:
Keep hands and fingers away from
the lever during the switching operation. Failure
to do so may cause personal injuries.
NOTE: If you remove the recipro saw blade without
rotating the blade clamp lever fully, the lever may not
be locked in the released position
rotate the blade clamp lever fully again, then make
sure that the blade clamp lever locked at the released
position .
NOTE: If the blade clamp lever is positioned inside
the tool, switch on the tool just a second to let the
blade out as shown in the figure. Remove the battery
cartridge from the tool before installing or removing
the recipro saw blade.

OPERATION

CAUTION:
Always press the shoe firmly
against the workpiece during operation. If the
shoe is removed or held away from the workpiece
during operation, strong vibration and/or twisting will
be produced, causing the blade to snap dangerously.
CAUTION:
Always wear gloves to protect
your hands from hot flying chips when cutting
metal.
CAUTION:
Be sure to always wear suitable
eye protection which conforms with current
national standards.
CAUTION:
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 recipro saw blade
into light contact with the workpiece. First, make a pilot
groove using a slower speed. Then use a faster speed
to continue cutting.

MAINTENANCE

CAUTION:
Always be sure that the tool is
switched off and the battery cartridge is removed
before attempting to perform inspection or
maintenance.
NOTICE:
Never use gasoline, benzine, thinner,
alcohol or the like. Discoloration, deformation or
cracks may result.

Replacing carbon brushes

► Fig.9: 1. Limit mark
Check the carbon brushes regularly.
Replace them when they wear down to the limit mark.
Keep the carbon brushes clean and free to slip in the
holders. Both carbon brushes should be replaced at the
same time. Use only identical carbon brushes.
1. Use a screwdriver to remove the brush holder
caps.
2. Take out the worn carbon brushes, insert the new
ones and secure the brush holder caps.
