FUNCTIONAL DESCRIPTION

• 
  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

• 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.

2. Red indicator
3. Battery cartridge

• 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

The tool is equipped with a battery protection system.
This system automatically cuts off power to the motor 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, turn the tool off and stop the application that caused the tool to become overloaded. Then turn the tool on to restart. If the tool does not start, the battery is overheated. In this situation, let the battery cool before turning the tool on 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.

NOTE:
The overheat protection works only with a battery cartridge with a star mark.

1. Star marking

Indication lamp with multi function

Indication lamps are located in two positions. When the battery cartridge is inserted on the tool with the slide switch positioned in the "O (OFF)" position, the indication lamp flickers quickly for approximately one second. If it does not flicker so, the battery cartridge or indication lamp has broken.

1. Indication lamp

• Overload protection
  • When the tool is overloaded, the indication lamp lights up. When the load on the tool is reduced, the lamp goes out.
  • If the tool continues to be overloaded and the indication lamp continues to light up for approximately two seconds, the tool stops. This prevents the motor and its related parts from being damaged.
  • In this case, to start the tool again, move the slide switch to the "O (OFF)" position once and then to the "I (ON)" position.
• Battery cartridge replacing signal
  • When the remaining battery capacity gets small, the indicator lamp lights up during operation earlier than enough capacity battery use.
• Accidental re-start preventive function
  • Even if the battery cartridge is inserted on the tool with the slide switch in the "I (ON)" position, the tool does not start. At this time, the lamp flickers slowly and this shows that the accidental re-start preventive function is at work.
  • To start the tool, first slide the slide switch toward the "O (OFF)" position and then slide it toward the "I (ON)" position.

Adjusting the depth of groove

6 grooving depths can be preset according to the size of biscuit to be used.
Refer to the table below for the correspondence between the sizes marked on the stopper and the biscuit size. Fine adjustments to the grooving depth can be made by turning the adjusting screw after loosening the hex nut. This may become necessary after the blade has been resharpened a few times.
