Attaching And Removing Blades - Hitachi CD 7SA Manual De Instrucciones

English
1. Place the main body (base) on the surface of the
work piece and align the slit on the forward edge
of the base with the sighting line. The arrow mark
on the projection in the dust cover (A) and the slit
in the base will be aligned and can be used for
positioning the metal cutter. (See Fig. 4)
If the sighting line is hard to see when working in
a dark place etc., turn on the LED light and align
the sighting line with the slit in the forward edge
of the base. (See Fig. 5)

2. Without allowing the blade to touch the material,
turn on the power switch. When the blade has
attained its maximum speed, push the metal
cutting saw slowly forward and maintain the same
speed until the cut is completed.
To keep the cut clean, push the saw forward at the
same speed.
3. The slit in the base indicats the position of the edge
of the blade at further end of the cut. This is useful
when cutting the work piece to a mid-way point.

ATTACHING AND REMOVING BLADES

CAUTION
●
Always turn the power switch off first and remove
the plug from the socket.

Use the box wrench that is supplied with the metal
cutting saw. Do not use other tools as this may
result in over-tightening or in sufficient tightening
of the wing bolt that holds the blade in place
causing accidents.
