Fig. 15
CAUTION:
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.
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.
Select a saw blade of the most appropriate length. Ideally, the length protruding from the base of the saw blade after subtracting the stroke should be larger than the material (see Fig. 16 and Fig. 18). 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. 17, Fig. 19)

1.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.
(1)Fasten a workpiece firmly before operation. (Fig. 20)
Fig. 20
(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.
2.Cutting lumber
When cutting lumber, make sure that the workpiece is fastened firmly before beginning. (Fig. 21)
Fig. 21
CAUTION:
Never apply any unreasonable force to the saw blade when cutting. Also remember to press the base against the lumber firmly.
3.Sawing curved lines
We recommend that you use the BIMETAL blade mentioned in 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.
4.Plunge cutting
With this tool, you can perform pocket 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. 23, Fig. 25, 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 14. Be sure to use caution during the cutting operation and observe the following procedures.
English
(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. 22, Fig. 23)
Fig. 22
Fig. 23
(2)Raise the handle slowly and cut in with the saw blade little by little. (Fig. 24, Fig. 25)
Fig. 24
Fig. 25

English
(3)Hold the body firmly until the saw blade completely cuts into the material. (Fig. 26, Fig. 27)
Fig. 26
Fig. 27
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 tip 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.
MAINTENANCE AND INSPECTION
WARNING: Be sure to switch power OFF and disconnect the plug from the receptacle during maintenance and inspection.
1.Inspecting the blade
Continued use of a dull or damaged blade will result in reduced cutting efficiency and may cause overloading of the motor. Replace the blade with a new one as soon as excessive abrasion is noted.
2.Inspecting the mounting screws
Regularly inspect all mounting screws and ensure that they are properly tightened. Should any of the screws be loosened, retighten them immediately.
WARNING: Using this reciprocating saw with loosen screws is extremely dangerous.
3.Maintenance of the motor
The motor unit winding is the very “heart“ of the power tool. Exercise due care to ensure the winding does noto become damaged and/or wet with oil or water.
4.Inspecting the carbon brushes (Fig. 28)
The Motor employs carbon brushes which are consumable parts. When they become worn to or near the “wear limit”, it could result in motor trouble. When an auto-stop carbon brush is equipped, the motor will stop automatically. At that time, replace both carbon brushes with new ones which have the same carbon brush Numbers shown in the figure. In addition, always keep carbon brushes clean and ensure that they slide freely within the brush holders.
