Operation - Hitachi Koki CR 13VST Manual De Instrucciones

English
Dial
(1) If you pull the trigger further in, the speed of the blade
accelerates. Begin cutting at a low speed to ensure
the accuracy of your target cut position. Once you've
obtained a suffi cient cutting depth, increase the
cutting speed.
(2) On the dial scale, "6" is the maximum speed and "1"
the minimum. The high speed is generally suitable
for soft materials such as wood, and the low speed
is suitable for hard materials such as metal. We
recommend that you use the following as a rough
guide in selecting the suitable speed for the materials
you are cutting.
Example of materials to be cut
Mild steel pipes /
cast-iron tubes / L-shaped angle
steel
Wood / wood with nails driven in
Stainless steel
Aluminum / brass / copper
Plaster board
Plastic / fi ber board
CAUTION
○ When cutting at low speed (scale of 1 – 2), never
cut a wooden board more than 25/64" (10 mm)
thick or a mild steel plate more than 5/64" (2
mm) thick. The load on the motor can result in
overheating and damage.
○ Although this unit employs a powerful motor,
prolonged use at a low speed will increase
the load unduly and may lead to overheating.
Properly adjust the saw blade to allow steady,
smooth cutting
unreasonable use such as sudden stops during
cutting operation.
10. Adjusting the orbital cutting operation
Two cutting systems can be selected with this unit.
The fi rst is straight cutting, in which the saw blade is
moved linearly, and the second is the orbital cutting,
in which the blade moves up and down, as well as
back and forth. (Fig. 10, Fig. 11)

operation,

avoiding
(1) Straight cutting
You can perform straight cutting by setting the change
lever widthwise. Straight cutting should normally be
performed when cutting hard materials such as metal,
etc. (Fig. 9)
Straight cutting
(2) Orbital cutting
You can perform orbital cutting by setting the change
lever lengthways.
Orbital cutting should normally be performed when
cutting soft materials such as wood, etc.
Orbital cutting is effi cient since the saw blade forcibly
bites into the material. (Fig. 10)
Orbital cutting
CAUTION
○ Even for soft materials, you should perform
straight cutting if you wish to make curved or
clean cuts.
○ Dust and dirt accumulated on the change lever
section can degrade the function of the change
lever. Periodically clean the change lever section.
○ When performing orbital cutting, use a saw with
straight blade. If a saw with curved blade is used,
the saw blade may be broken or the unit may be
damaged.
OPERATION
WARNING
Never touch the moving parts.
CAUTION
any
○ Avoid carrying it plugged to the outlet with your
fi nger on the switch. A sudden startup can result
in an unexpected injury.
○ Be careful not to let sawdust, earth, moisture,
etc., enter the inside of the machine through the
plunger section during operation. If sawdust
and the like accumulate in the plunger section,
always clean it before use.
