Too little pressure on the handle may result in more
•
sparks and premature blade wear.
Do not touch the blade, workpiece or cutting chips
•
immediately after
extremely hot and could burn your skin.
If the blade stops during operation, makes an odd
•
noise or begins to vibrate, switch off the tool
immediately. Replace cracked or damaged blade
with a new one.
Hold the handle firmly. Switch on the tool and wait until
the blade attains full speed. Then lower the handle
gently to bring the blade close to the workpiece. When
the blade makes contact, ease into the cut gently at first,
then gradually add pressure as the cutting position
steadies. Your pressure on the handle should be
adjusted to produce the minimum amount of sparks.
When the cut is completed, switch off the tool and WAIT
UNTIL THE BLADE HAS COME TO A COMPLETE
STOP before returning the handle to the fully elevated
position. If the handle is raised while the blade is still
rotating, the piece cut off may be caught by the blade,
causing dangerous scattering of chips. When cutting
only part of the way into a workpiece, raise the handle
while the blade is rotating. Switching off during the cut
may cause damage to the carbide-tips as they contact
the workpiece.
Cutting angles
Secure the workpiece in the vise as shown in the Figure
A and proceed to cut it. The saw blade life will be
shortened if the workpiece is cut as shown in the Fig B.

CAUTION:
Do NOT cut the workpiece as shown in the Fig. C

possibly resulting in injury.
The saw blade is subjected to greater wear when the
area A in the Fig. B is cut. Place a wooden block up
against the workpiece as shown in the Fig. D so that the
saw blade will enter area A at an angle. This will help to
extend the saw blade life.
The allowable cutting dimensions are reduced when a
wooden block is used. Use a wooden block whose
dimensions are equivalent to the maximum allowable
cutting dimensions minus the dimensions of the
workpiece to be cut. This will further minimize the
shortening of the saw blade life.
Cutting pipes, squares and channels
The saw blade is subjected to greater wear when the
areas A and B in figure F and figure G are cut. Place a
wooden block up against the workpiece as shown in
figure H and figure I so that the saw blade will enter
areas A and B at an angle. This will help to minimize the
shortening of the saw blade life.
