Metal Cutting - Ratio SR800NM Manual De Instrucciones

material thickness to be cut. Always ensure the
work–piece is firmly held or clamped to prevent
movement. For easier control, select low speed to
start cutting, then increase to suitable speed.
Any movement of the material may affect the cut
quality. The blade cuts on the upward stroke and
may chip the uppermost. Ensure your uppermost
surface is a non-visible surface when your work is
finished.

1. METAL CUTTING

Use a finer tooth blade for ferrous metals and a
coarse tooth blade for non-ferrous metals. When
cutting thin sheet metals always clamp wood
on both sides of the sheet to reduce vibration or
tearing of the sheet metal. Both wood and sheet
metal must be cut. Do not force the cutting blade
when cutting thin metal or sheet steel, as they
are harder materials and will take longer to cut.
Excessive blade force may reduce the life of
the blade or damage the motor. To reduce heat
during metal cutting, add a little lubricant along the
cutting line.
2. CUTTING GROOVES / WINDOW HOLES
(SEE FIG.I)

1) For wood
Align the blade direction with the grain of the
wood. Position the rounded part at the front of the
base plate on the surface to be cut. Lower the
saw slowly into the material at the chosen point of
entry. Lower the saw in a pivoting action until the
blade has cut through the other side. Do not move
the saw along the intended cut line until the blade
has cut through and the base plate is laying flat on
the material.
2) For other materials
For materials other than wood when cutting
window holes, firstly drill a hole with a drill or other
similar tool from which initial cutting will begin.
3. ANGULAR CUTTING (SEE FIG J,K,L,M)
NOTE: The hex key is stored at the rear of the jig
saw. Place it back when not in use.

For adjustment of the angle of inclination, loose
the Allen bolt and screw on the base of saw.
Move the base plate forward or backward until
the pin unlatches the slot. Then you can rotate
the base plate to the required angle. The angle
