Overload Protection; Overheat Protection; Overdischarge Protection - Makita DTW1005Z Instruction Manual

Overload protection

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

Overheat protection

When the tool is overheated, the tool stops automati-
cally and the lamps blink. 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.
Protections against other causes
Protection system is also designed for other causes
that could damage the tool and allows the tool to stop
automatically. Take all the following steps to clear the
causes, when the tool has been brought to a temporary
halt or stop in operation.
1. Make sure that all switch(es) is/are in the off posi-
tion, and then turn the tool on again to restart.
2. Charge the battery(ies) or replace it/them with
recharged battery(ies).
3. Let the tool and battery(ies) cool down.
If no improvement can be found by restoring protection
system, then contact your local Makita Service Center.
