How To Use The Reciprocating Saw - Hitachi CR 13VA Instruction Manual And Safety Instructions

English
10. Adjusting the swing cutting operation
Two cutting systems can be selected with this
unit. The first is straight cutting, in which the
saw blade is moved linearly, and the second is
the swing cutting, in which the saw blade is
swung like a pendulum. (Fig. 14, Fig. 15)
(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. 14)
(2) Swing cutting
You can perform swing cutting by setting
the change lever lengthways. Swing cutting
should normally be performed when cutting
soft materials such as wood, etc.
Swing cutting is efficient since the saw blade
forcibly bites into the material. (Fig. 15)
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.

HOW TO USE THE RECIPROCATING SAW

CAUTION:
Avoid carrying it plugged to the outlet with your finger 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.
Do not remove the front cover (refer to Fig. 2).
Be sure to hold the body from the top of the front cover.
During use, press the base against the material while cutting.
Vibration can damage the saw blade if the base is not pressed firmly against the
workpiece.
Furthermore, a tip of the saw blade can sometimes contact the inner wall of the pipe,
damaging the saw blade.
