(1)Turn on and off the switching trigger several times so that the lever can jump out of the front cover completely. Thereafter, turn off the switch and
remove the battery (Fig. 5).
CAUTION
Be absolutely sure to keep the switch turned off and the battery removed to prevent any accident.
(2)Push the lever in the direction of the arrow mark shown in Fig. 6 marked on the lever (Fig. 6).
(3)Insert the saw blade all the way into the small slit of the plunger tip with the lever pushing. You can mount this blade either in the upward or downward direction (Fig. 7, Fig. 8).
(4)When you release the lever, the spring force will return the lever to the correct position automatically (Fig. 9).
(5)Pull the back of the saw blade two or three times by hand and check that the blade is securely mounted. When pulling the blade, you will know it is properly mounted if it clicks and the lever moves slightly (Fig. 10).
CAUTION
When pulling the saw blade, be absolutely sure to pull it from the back. Pulling other parts of the blade will result in an injury.
2. Dismounting the blade
(1)Turn on and off the switching trigger several times so that the lever can jump out of the front cover
completely. Thereafter, turn off the switch and remove the battery (Fig. 5).
CAUTION
Be absolutely sure to keep the switch turned off and the battery removed to prevent any accident.
(2)After you have pushed the lever in the direction of the arrow mark shown in Fig. 6 and secured it, 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. 11).
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. 12, 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. 13 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 saw-blade-installed area can function smoothly.
CAUTION
Do not use any saw blade with a worn-out blade hole. Otherwise, the saw blade can come off, resulting in personal injury (Fig. 14).
3.Moving the base
Loosen the set screw and move the base forward, as shown in Fig. 15, Fig. 16. Tighten the set screw slightly, ensure the base does not move back and forth, and firmly tighten the set screw. Ensure that the base does not contact the blade.
4.Confirm that the battery is mounted correctly
HOW TO USE
CAUTION
◯Do not carry tools 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 (refer to Fig. 5).
◯Do not remove the front cover.
Be sure to hold the body from the top of the front cover (refer to Fig. 5).
◯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. 18 and Fig. 20).
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. 19, Fig. 21).
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. 17).
Always lock the switch when carrying or storing the tool eliminate unintentional starting.
