(2)After you have pushed the lever in the direction of the arrow mark shown in Fig. 2, turn the blade so it faces downward. The blade should fall out by itself. If the blade doesn’t fall out, pull it out by
hand.
CAUTION
Never touch the saw blade immediately after use. The metal is hot and can easily burn your skin.
WHEN THE BLADE IS BROKEN
Even when the saw blade is broken and remains inside the small slit of the plunger, it should fall out if you push the lever in the direction of the arrow mark, and face the blade downward. If it doesn’t fall out itself, take it out using the procedures explained below.
(1)If a part of the broken saw blade is sticking out of the small slit of the plunger, pull out the protruding part and take the blade out.
(2)If the broken saw blade is hidden inside the small slit, hook the broken blade using a tip of another saw blade and take it out (Fig. 7).
MAINTENANCE AND INSPECTION OF SAW BLADE MOUNT
(1)After use, blow away sawdust, earth, sand, moisture, etc., with air or brush them away with a brush, etc., to ensure that the blade mount can function smoothly.
(2)As shown in Fig. 8, carry out lubrication around the blade holder on a periodic basis by use of cutting fluid, etc.
NOTE
Continued use of the tool without cleaning and lubricating the area where the saw blade is installed can result in some slack movement of the lever due to accumulated sawdust and chips. Under the circumstances, pull a rubber cap provided on the lever in the direction of an arrow mark as shown in Fig. 9 and remove the rubber cap from the lever. Then, clean up the inside of the blade holder with air and the like and carry out sufficient lubrication. The rubber cap can be fitted on if it is pressed firmly onto the lever. At this time, make certain that there exists no clearance between the blade holder and the rubber cap, and furthermore ensure that the

6. Adjusting the base
(1)Lift the front cover up as illustrated in Fig. 11.
(2)If a base setting screw is loosened with an attached hexagonal bar wrench, you can adjust a base installing position (Fig. 12, Fig. 13).
(3)After adjusting the base installing position, tighten the base setting screw with the attached hexagonal bar wrench completely.
7.Adjusting the blade reciprocating speed
This unit has a
Once you’ve obtained a sufficient cutting depth, increase the cutting speed.
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
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. 1). 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 quantity should be larger than the material (see Fig. 15 and Fig. 17). 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. 16, Fig. 18).
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. 19).
(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.
2. Cutting lumber
When cutting lumber, make sure that the workpiece is fastened firmly before beginning (Fig. 20).
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
