Adjusting the shoe
When the blade loses its cutting efficiency in one place
along its cutting edge, reposition the shoe to utilize a
sharp, unused portion of its cutting edge. This will help
to lengthen the life of the blade.
To reposition the shoe, push the shoe button in the "A"
direction with a click and reposition as shown in the
figure which allows you to make five-way adjustment. To
secure the shoe, push the shoe button in the "B" direc-
tion with a click.

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 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.
For Model M4500
To install the blade, loosen the bolt on the blade clamp
with the hex wrench. Insert the blade between the blade
clamp and the slider so that the pin on the slider fits into
the hole in the blade shank. If the pin cannot easily fit
into the hole, remove the hex wrench from the screw
and then try again.
After the pin fits properly into the hole, tighten the screw
clockwise securely. Make sure that the blade cannot be
extracted even though you try to pull it out.

CAUTION:
If you tighten the screw without the
pin on the slider fitting properly in the hole in the blade
shank, the pin or the blade shank will be damaged.
This may cause the blade to be extracted unexpect-
edly during operation.
To remove the blade, follow the installation procedure
in reverse.
For Model M4501
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 .

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.
CAUTION:
Keep hands and fingers away from
the lever during the switching operation. Failure to
do so may cause personal injuries.
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
► Fig.8: 1. Recipro saw blade 2. Blade clamp lever
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 lever is positioned inside the tool, switch
on the tool just a second to let the blade clamp out.
Switch off and unplug the tool from the mains before
working on the blade clamp lever.
Hex wrench storage
When not in use, store the hex wrench as shown in the
figure to keep it from being lost.

OPERATION
CAUTION:
Always hold the tool firmly with
one hand on insulation cover and the other on the
switch handle.
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 complies 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
