(4) Make sure that the base is not interfering with the blade
WARNING
To avoid injury and damage, do not operate the saw without the base in place. The plunger may strike against the workpiece and damage the reciprocating mechanism.
9. Adjusting the blade reciprocating speed
This unit has a built-in electronic control circuit that makes it possible to adjust the variable speed of the saw blade either both by pulling a switching trigger or turning a dial. (Fig. 9)
text_image
Switch trigger Dial GraduationFig. 9
(1) If you pull the trigger further in, the speed of the blade accelerates. Begin cutting at a low speed to ensure the accuracy of your target cut position. Once you've obtained a sufficient cutting depth, increase the cutting speed.
(2) On the dial scale, "6" is the maximum speed and "1" the minimum. The high speed is generally suitable for soft materials such as wood, and the low speed is suitable for hard materials s recommend that you use the following as a rough guide in selecting the suitable speed for the materials you are cutting.
| Example of materials to be cut | Recommended dial scale |
| Mild steel pipes / cast-iron tubes / L-shaped angle steel | 2 – 5 |
| Wood / wood with nails driven in 6 | |
| Stainless steel 1 – 3 | |
| Aluminum / brass / copper 2 – 5 | |
| Plaster board 5 – 6 | |
| Plastic / fi ber board 1 – 3 |
CAUTION
When cutting at low speed (scale of 1 – 2), never cut a wooden board more than 25/64" (10 mm) thick or a mild steel plate more than 5/64" (2 mm) thick. The load 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 orbital 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 orbital cutting, in which the blade moves up and down, as well as back and forth. (Fig. 10, Fig. 11)
(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. 9)
text_image
Straight cutting Change leverFig. 10
(2) Orbital cutting
You can perform orbital cutting by setting the change lever lengthways.
Orbital cutting should normally be performed when cutting soft materials such as wood, etc.
Orbital cutting is efficient since the saw blade forcibly bites into the material. (Fig. 10)
text_image
metal. We Change lever Orbital cuttingFig. 11
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 orbital 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.
OPERATION
WARNING
Never touch the moving parts.
CAUTION
○ Avoid carrying it plugged to the outlet with your fi nger 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. 1). Hold firmly the front cover by hand to operate.
But, do not extend your hand or fi nger beyond the fl ange (see Fig.12) 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.
○ 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 ma Fig. 12 and Fig. 13)

natural_image
Line drawing of a hand using a tool to lift a cylindrical object (no text or symbols present)Fig. 17
(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) Use the dial to adjust the speed of the saw blade to suit your working conditions and materials.
(4) You can cut smoothly if you set the change lever position to straight cutting (Fig. 10).
- Cutting lumber
(1) When cutting lumber, make sure that the workpiece is fastened firmly before beginning. (Fig. 18)
natural_image
Line drawing of a hand using a saw tool to lift a wooden block (no text or symbols)Fig. 18
(2) You can cut efficiently if the speed of the saw blade is set to dial scale "6".
(3) You can cut efficiently if the change lever position is set to orbital cutting (Fig. 11). Alternatively, you can cut cleanly if the change lever position is set to straight cutting (Fig. 10).
CAUTION
Never apply any unreasonable force to the saw blade when cutting. Also remember to press the base against the lumber firmly.
- Sawing curved lines
We recommend that you use the BIMETAL blade mentioned in Page 16 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.
- Plunge cutting
With this tool, you can perform plunge cutting on plywood panels and thin board materials. You can carry out plunge cutting quite easily with the saw blade installed in reverse as illustrated in Fig. 20, Fig. 22, and Fig. 24. 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 16. 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. 19, Fig. 20)
