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

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
operation, avoiding any unreasonable
use such as sudden stops during cutting
operation.
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. 16, Fig. 17)
(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. 16)

(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. 17)

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 swing 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.
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).
Hold firmly the front cover by hand to
operate.
But, do not extend your hand or finger
beyond the flange (see Fig.18) of front
cover to avoid an injury.
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.
