⅜ Do not remove the front cover.

Be sure to hold the body from the top of the front

cover (refer to Fig. 6).

⅜ 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.

⅜ 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

⅜ Press the base firmly against the workpiece.

⅜ Never apply any unreasonable force to the saw

blade when cutting. Doing so can easily break the

blade.

⅜ 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 firmly 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 firmly before beginning (Fig. 24).

CAUTION

⅜ Never apply any unreasonable force to the saw

blade when cutting. Also remember to press the

base against the lumber firmly.

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).

(3) Hold the body firmly until the saw blade completely

cuts into the material (Fig. 29, Fig. 30).

CAUTION

⅜ Avoid plunge cutting for metallic materials. This can

easily damage the blade.

⅜ 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.

⅜ Make absolutely sure that you cut slowly while

holding the body firmly. 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 efficiency 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

⅜ 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.
