4. Charge the battery cartridge once in every six months if you do not use it for a long period of time.

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 the battery cartridge
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.
  Battery protection system (Lithium-ion battery with star marking)
  Fig.2 Lithium-ion batteries with a star marking are equipped with a protection system. This system automatically cuts off power to the tool to extend battery life. The tool will automatically stop during operation if the
  tool and/or battery are placed under one of the following conditions:

• Overloaded:
  The tool is operated in a manner that causes it to draw an abnormally high current.  In this situation, release the switch lever/trigger on the tool and stop the application that caused the tool to become overloaded. Then pull the switch lever/trigger again to restart. If the tool does not start, the battery is overheated. In this situation, let the battery cool before pulling the switch lever/trigger again.

• Low battery voltage:
  The remaining battery capacity is too low and the tool will not operate. In this situation, remove and recharge the battery.

Switch action
CAUTION:

• Before installing the battery cartridge into the tool, always check to see that the switch lever/trigger actuates properly and returns to the “OFF” position when released.

Fig.3
To prevent the switch lever/trigger from accidentally pulled, the lock-off lever/button are provided. To start the tool, pull either the switch lever or trigger.

• For the switch lever, pull the lock-off lever and then pull the switch lever to start the tool.
• For the switch trigger, depress the lock-off button and then pull the switch trigger to start to the tool. The lock-off button can be pressed from either right or left.

The tool speed is increased by increasing pressure on the switch lever/trigger. Release the switch lever/trigger to stop.

NOTICE:
Do not pull the switch lever/trigger hard without pulling the lock-off lever/button. This can cause switch breakage.
Lighting up the front lamp
Fig.4
CAUTION:

• Do not look in the light or see the source of light directly. Pull the switch lever/trigger to light up the lamp. The lamp keeps on lighting while the switch lever/trigger is being pulled. The lamp automatically turns off 10-15 seconds after releasing the switch lever/trigger.

Adjusting the shoe
Fig.5
When the blade loses its cutting efficiency in one place along its cutting edge, reposition the shoe to utilize a sharp, unused portion of its cutting edge. This will help to lengthen the life of the blade. To reposition the shoe, loosen the bolt with hex wrench. Slide the shoe to the desired position and then tighten the bolt firmly.

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 the saw blade
CAUTION:

• Always clean out all chips or foreign matter adhering to the blade, blade clamp and/or slider. Failure to do so may cause insufficient tightening of the blade, resulting in a serious injury.

For Model DJR143, DJR183
Fig.6
Insert the recipro saw blade into the blade clamp as far as it will go. The blade clamp sleeve rotates and fixes the saw blade. Make sure that the saw blade cannot be extracted even though you try to pull it out.
CAUTION:

• If you do not insert the saw blade deep enough, the saw blade may be ejected unexpectedly during operation. This can be extremely dangerous.

NOTE:

• You can not use the jig saw blade with DJR143 or DJR183.

Fig.7
To remove the saw blade, rotate the blade clamp sleeve in the direction of the arrow fully. The saw blade is removed and the blade clamp sleeve is fixed at the released position.
