(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 firmly 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 firmly before operation (Fig. 22).

(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. 23).

CAUTION

◯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 7 (Page 20) 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. 25, Fig. 26, and Fig. 27. 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 20, Table 7. 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. 24, Fig. 25).

(2)Raise the handle slowly and cut in with the saw blade little by little (Fig. 26, Fig. 27).

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

cuts into the material (Fig. 28, Fig. 29).

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 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

◯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 6 is engraved in the vicinity of the mounting position of each blade. Select appropriate blades by referring to Tables 6 and 8 below.

Table 6: HCS blades

	30 mm in diameter
No. 3	For cutting steel pipe less than	Below 3.5
	30 mm in diameter
No. 4	For cutting and roughing lumber	50 – 70
No. 5	For cutting and roughing lumber	Below 30
No. 8	For cutting vinyl chloride pipe less	2.5 – 15
	than 100 mm in diameter
	For cutting and roughing lumber	Below 100
No. 9	For cutting mild steel pipe less
	than 100 mm in diameter when	2.5 – 6
	used with cut off guide
No. 95	For cutting stainless steel pipe	Below 2.5
	less than 100 mm in diameter
