FUNCTIONAL DESCRIPTION

 CAUTION:
Always be sure that the tool is switched off and the battery cartridge is removed before adjusting or checking function on the tool.

Installing or removing battery cartridge (Fig. 1)

CAUTION: 

• Always switch off the tool before installing or removing of the battery cartridge.
• Hold the tool and the battery cartridge firmly when installing or removing battery cartridge. Failure to hold the tool and the battery cartridge firmly may cause them to slip off your hands and result in damage to the tool and battery cartridge and a personal injury.

To remove the battery cartridge, slide it from the tool while sliding the button on the front of the cartridge.
To install the battery cartridge, align the tongue on the battery cartridge with the groove in the housing and slip it into place. Insert it all the way until it locks in place with a little click. If you can see the red indicator on the upper side of the button, it is not locked completely.

CAUTION:

• Always install the battery cartridge fully until the red indicator cannot be seen. If not, it may accidentally fall out of the tool, causing injury to you or someone around you.
• Do not install the battery cartridge forcibly. If the cartridge does not slide in easily, it is not being inserted correctly.

Tool/battery protection system 

The tool is equipped with a tool/battery protection system.
This system automatically cuts off the power to extend tool and battery life. The tool will automatically stop during operation if the tool or battery is placed under one of the following conditions:

Overload protection 

This protection works when the tool is operated in a manner that causes it to draw an abnormally high current.
In this situation, turn the tool off and stop the application that caused the tool to become overloaded. Then turn the tool on to restart.

Overheat protection
This protection works when the tool or battery is overheated. In this situation, let the tool and battery cool before turning the tool on again.

Overdischarge protection
This protection works when the remaining battery capacity gets low. In this situation, remove the battery from the tool and charge the battery.

Indicating the remaining battery capacity 

Only for battery cartridges with the indicator (Fig. 2) Press the check button on the battery cartridge to indicate the remaining battery capacity. The indicator lamps light up for a few seconds.

NOTE

• Depending on the conditions of use and the ambient temperature, the indication may differ slightly from the actual capacity.
• The first (far left) indicator lamp will blink when the battery protection system works.

Selecting the cutting action (Fig. 3) 

This tool can be operated with an orbital or a straight line (up and down) cutting action. The orbital cutting action thrusts the blade forward on the cutting stroke and greatly increases cutting speed.
To change the cutting action, just turn the cutting action changing lever to the desired cutting action position. Refer to the table to select the appropriate cutting action.

Switch action 

CAUTION:
Before inserting the battery cartridge into the tool, always check to see that the switch trigger actuates properly and returns to the “OFF” position when released. (Fig. 4)

To start the tool:
Press the lock switch to turn the tool into standby mode. It turns the lamp on, too.
Pull the switch trigger to start the tool. Release the switch trigger to stop.
For continuous operation, pull the switch trigger and then push in the lock on button.
To stop the tool from the locked position, pull the switch trigger fully, and then release it.
In standby mode, press the lock switch to turn the lamp off and turn the tool into lock-off mode.

NOTE

• The lock switch does not actuate during cutting operation.
• When the tool is in standby mode, the lamp keeps lighting.
• If the tool is left 10 seconds without any operations in standby mode, the tool is automatically turned into lock-off mode and the lamp goes off.

Lighting up the lamps 

CAUTION:
Do not look in the lamp or see the source of lamp directly.

To turn on the lamp, press the lock switch.
To turn off the lamp within 10 seconds, press the lock switch again.

NOTE: 

• Use a dry cloth to wipe the dirt off the lens of lamp. Be careful not to scratch the lens of lamp, or it may lower the illumination.
• When the tool is overheated, the lamp flickers. Cool down the tool fully before operating again.

Speed adjusting dial (Fig. 5) 

The tool speed can be infinitely adjusted by turning the speed adjusting dial. You can get the highest speed at 6 and the lowest speed at 1.
Refer to the table to select the proper speed for the workpiece to be cut. However, the appropriate speed may differ with the type or thickness of the workpiece. In general, higher speeds will allow you to cut workpieces faster but the service life of the blade will be reduced.

CAUTION:
The speed adjusting dial can be turned only as far as 6 and back to 1. Do not force it past 6 or 1, or the speed adjusting function may no longer work.

Electronic function 

The tool is equipped with the electronic functions for easy operation.

• Soft start
  The soft-start function minimizes start-up shock, and makes the tool start smoothly.
• Soft no-load rotation
  To reduce the vibration and align the jig saw blade with the cutting line easily, the tool automatically reduces the rotation speed until the tool starts cutting the workpiece when the speed adjusting dial is set at 3 or higher. Once the tool starts cutting the workpiece, the tool speed reaches the preset speed and keeps the speed until the tool stops.

NOTE:
When the temperature is low, this function may not be available.

Disabling or enabling the soft no-load rotation function

To disable or enable the soft no-load rotation function, follow the steps below.

1. Make sure that the tool is turned off.
2. Set the speed adjusting dial to “1”.
3. Press the lock switch to turn on the tool.
4. Turn the speed adjusting dial to “6”, and then set it back to “1”.

The lamp blinks twice when the soft no-load rotation function is disabled or enabled. To enable or disable this function again, perform the same procedure again.

NOTE

• If the soft no-load rotation function is disabled, the lamp blinks twice when the tool is turned on.
• You can also disable or enable the soft no-load rotation function by changing the speed adjusting dial to “6” – “1” – “6”.

ASSEMBLY

CAUTION
Always be sure that the tool is switched off and the battery cartridge is removed before carrying out any work on the tool.

Installing or removing saw blade

CAUTION:

• Always clean out all chips or foreign matter adhering to the blade and/or blade holder. Failure to do so may cause insufficient tightening of the blade, resulting in a serious personal injury.
• Do not touch the blade or the workpiece immediately after operation; they may be extremely hot and could burn your skin.
• Tighten the saw blade securely. Failure to do so may cause a serious injury.
• When you remove the saw blade, be careful not to hurt your fingers with the top of the blade or the tips of workpiece. (Fig. 6)

Before installing the blade, make sure that the blade holder is in the released position.
To install the blade, insert the blade (teeth facing forward) into the blade holder until it latches. The blade holder moves to the fixed position by itself and the blade is locked. Pull the blade lightly to make sure that the blade does not fall off during operation.

CAUTION:
Do not open the tool opener excessively, or it may cause tool damage. (Fig. 7)

To remove the blade, push the tool opener forward as far as it will go. This allows the blade to be released.

NOTE: In case that it is difficult to remove the jig saw blade:
Turn the cutting action changing lever to the position “III” and move the jig saw blade holder to the bottom before pushing the blade clamp lever to the released position. To move the jig saw blade holder to the bottom, return the blade clamp lever fully to the fixed position once and slightly switch on the tool several times.

NOTE:
Occasionally lubricate the roller

Hex wrench storage (Fig. 8) 

When not in use, store the hex wrench as shown in the figure to keep it from being lost.

Cover plate (Fig. 9) 

Use the cover plate when cutting decorative veneers, plastics, etc. It protects sensitive or delicate surfaces from damage. Fit it on the back of the tool base.

Anti-splintering device (Fig. 10) 

For splinter-free cuts, the anti-splintering device can be used. To install the anti-splintering device, move the tool base all the way forward and fit it from the back of tool base. When you use the cover plate, install the antisplintering device onto the cover plate.

CAUTION:
The anti-splintering device cannot be used when making bevel cuts.

Dust extraction 

The dust nozzle (optional accessory) is recommended to perform clean cutting operations. (Fig. 11)
To attach the dust nozzle on the tool, insert the hook of dust nozzle into the hole in the base. (Fig. 12)
To secure the dust nozzle, tighten the clamp screw at the front of the dust nozzle.
The dust nozzle can be installed on either left or right side of the base. (Fig. 13)
Then connect a Makita vacuum cleaner to the dust nozzle.

OPERATION

CAUTION:
Always hold the base flush with the workpiece. Failure to do so may cause blade breakage, resulting in a serious injury

NOTE:
If the tool is operated continuously until the battery cartridge has discharged, allow the tool to rest for 15 minutes before proceeding with a fresh battery. (Fig. 14)

Turn the tool on without the blade making any contact and wait until the blade attains full speed. Then rest the base flat on the workpiece and gently move the tool forward along the previously marked cutting line.
When cutting curves, advance the tool very slowly.

Bevel cutting (Fig. 15) 

CAUTION:
Always be sure that the tool is switched off and the battery cartridge is removed before tilting the base. With the base tilted, you can make bevel cuts at any angle between 0° and 45° (left or right). (Fig. 16)
To tilt the base, loosen the bolt on the back of the base with the hex wrench. Move the base so that the bolt is positioned in the center of the bevel slot in the base. (Fig. 17)
Tilt the base until the desired bevel angle is obtained. The V-notch of the gear housing indicates the bevel angle by graduations. Then tighten the bolt firmly to secure the base.

Front flush cuts (Fig. 18) 

Loosen the bolt on the back of the base with the hex wrench and slide the base all the way back. Then tighten the bolt to secure the base.

Cutouts
Cutouts can be made with either of two methods A or B.

A) Boring a starting hole: (Fig. 19) 

For internal cutouts without a lead-in cut from an edge, pre-drill a starting hole 12 mm or more in diameter. Insert the blade into this hole to start your cut.

B) Plunge cutting: (Fig. 20) 

You need not bore a starting hole or make a lead-in cut if you carefully do as follows.

1. Tilt the tool up on the front edge of the base with the blade point positioned just above the workpiece surface.
2. Apply pressure to the tool so that the front edge of the base will not move when you switch on the tool and gently lower the back end of the tool slowly.
3. As the blade pierces the workpiece, slowly lower the base of the tool down onto the workpiece surface.
4. Complete the cut in the normal manner.

Finishing edges (Fig. 21) 

To trim edges or make dimensional adjustments, run the blade lightly along the cut edges.

Metal cutting 

Always use a suitable coolant (cutting oil) when cutting metal. Failure to do so will cause significant blade wear.
The underside of the workpiece can be greased instead of using a coolant.

Rip fence set (optional accessory) 

CAUTION:
Always be sure that the tool is switched off and the battery cartridge is removed before installing or removing accessories.

Straight cuts (Fig. 22) 

When repeatedly cutting widths of 160 mm or less, use of the rip fence will assure fast, clean, straight cuts. (Fig. 23) To install, insert the rip fence into the rectangular hole on the side of the tool base with the fence guide facing down. Slide the rip fence to the desired cutting width position, then tighten the bolt to secure it.

Circular cuts (Fig. 24 & 25) 

When cutting circles or arcs of 170 mm or less in radius, install the rip fence as follows.

1. Insert the rip fence into the rectangular hole on the side of the base with the fence guide facing up. Insert the circular guide pin through either of the two holes on the fence guide. Screw the threaded knob onto the pin to secure the pin.
2. Now slide the rip fence to the desired cutting radius, and tighten the bolt to secure it in place. Then move the base all the way forward.

NOTE:
Always use blades No. B-17, B-18, B-26 or B-27 when cutting circles or arcs.

Guide rail adapter set (optional accessory) (Fig. 26)

When cutting parallel and uniform width or cutting straight, the use of the guide rail and the guide rail adapter will assure the production of fast and clean cuts.
To install the guide rail adapter, insert the rule bar into the square hole of the base as far as it goes. Secure the bolt with the hex wrench securely. (Fig. 27)
Install the guide rail adapter on the rail of the guide rail.
Insert the rule bar into the square hole of the guide rail adapter. Put the base to the side of the guide rail, and secure the bolt securely. (Fig. 28)
