Selection Of Blades - HIKOKI CR18DMR Instrucciones De Manejo

English
○ Select a saw blade of the most appropriate length.
Ideally, the length protruding from the base of the saw
blade after subtracting the stroke quantity should be
larger than the material (see Fig. 19 and Fig. 21).
If you cut a large pipe, large block of wood, etc., that
exceeds the cutting capacity of a blade; there is a risk
that the blade may contact with the inner wall of the
pipe, wood, etc., resulting in damage (Fig. 20, Fig. 22).
1. Switch operation
(1) Lock-off button
The tool is equipped with a lock-off button. To activate
the trigger lock, move the button to the right position.
Move the button to the left to operate the tool (Fig. 18).
Always lock the switch when carrying or storing the tool
eliminate unintentional starting.
(2) Trigger switch
This tool is equipped with a variable speed controlled
trigger switch. The tool can be turned "ON" or "OFF" by
squeezing or releasing the trigger. The blade plunger
stroke rate can be adjusted from the minimum to
maximum nameplate stroke rate by the pressure you
apply to the trigger. Apply more pressure to increase
the speed and release pressure to decrease speed.
2. Cutting metallic materials
CAUTION
○ Press the base fi rmly against the workpiece.
○ Never apply any unreasonable force to the saw blade
when cutting. Doing so can easily break the blade.
○ The motor can be locked sometimes, depending
on the combination of the material to be cut and the
blade. Whenever the motor gets locked, switch it off
immediately.
(1) Fasten a workpiece fi rmly before operation (Fig. 23).
(2) When cutting metallic materials, use proper machine
oil (turbine oil, etc.). When not using liquid machine oil,
apply grease over the workpiece.
CAUTION
The service life of the saw blade will be drastically
shortened if you don't use machine oil.
3. Cutting lumber
When cutting lumber, make sure that the workpiece is
fastened fi rmly before beginning (Fig. 24).
CAUTION
○ Never apply any unreasonable force to the saw blade
when cutting. Also remember to press the base against
the lumber fi rmly.
4. Sawing curved lines
We recommend that you use the BI-METAL blade
mentioned in Table 4 (Page 14) for the saw blade since
it is tough and hardly breaks.
CAUTION
Delay the feed speed when cutting the material into
small circular arcs. An unreasonably fast feed may
break the blade.
5. Plunge cutting
With this tool, you can perform plunge cutting on
plywood panels and thin board materials. You can
carry out pocket cutting quite easily with the saw blade
installed in reverse as illustrated in Fig. 26, Fig. 28,
and Fig. 30. Use the saw blade that is as short and
thick as possible. We recommend for this purpose that
you use BI-METAL Blade No. 132 mentioned in Page
14, Table 4. Be sure to use caution during the cutting
operation and observe the following procedures.
(1) Press the lower part (or the upper part) of the base
against the material. Pull the switch trigger while
keeping the tip of the saw blade apart from the material
(Fig. 25, Fig. 26).
(2) Raise the handle slowly and cut in with the saw blade
little by little (Fig. 27, Fig. 28).
13
(3) Hold the body fi rmly until the saw blade completely cuts
into the material (Fig. 29, Fig. 30).
CAUTION
○ Avoid plunge cutting for metallic materials. This can
easily damage the blade.
○ Never pull the switch trigger while the tip of the saw
blade is pressed against the material. If you do so, the
blade can easily be damaged when it collides with the
material.
○ Make absolutely sure that you cut slowly while holding
the body fi rmly. If you apply any unreasonable force to
the saw blade during the cutting operation, the blade
can easily be damaged.
NOTE
The use of the battery EB1826HL and EB1830HL in
a cold condition (below 0 degree Centigrade) can
sometimes result in the weakened cutting torque and
reduced amount of work. This, however, is a temporary
phenomenon, and returns to normal when the battery
warms up.

SELECTION OF BLADES

To ensure maximum operating effi ciency and results, it is
very important to select the appropriate blade best suited
to the type and thickness of the material to be cut.
NOTE
○ Dimensions of the workpiece mentioned in the table
represent the dimensions when the mounting position
of the base is set nearest to the body of the Cordless
Reciprocating Saw. Caution must be exercised since
dimensions of the workpiece will become smaller if the
base is mounted far away from the body of the Cordless
Reciprocating Saw.
1. Selection of HCS blades
The blade number of HCS blades in Table 3 is engraved
in the vicinity of the mounting position of each blade.
Select appropriate blades by referring to Tables 3 and
5 below.
