PROBLEM SOLUTION

1. WHY YOUR DRILL SUDDENLY STOPS 
WHEN WORKING.

a)   They run at full power until they need charging. So if 

your tool suddenly stops check your battery first. The 
Li-ion battery is protected against deep discharging by 
the “Discharging Protection System”. When the battery 
is empty, the machine is switched off by means of a 
protective circuit, and the drill bit will be stop working.

b)   Overload protection. When overloaded, the motor 

comes to a stop. Relieve the load on the machine 
immediately and allow cooling for approx. 30 seconds 
at the highest no-load speed.

c)   High temperature of the tool or battery. When the load 

is too high or the allowable battery temperature of 75 
°C is exceeded, the electronic control switches off 
the power tool until the temperature is in the optimum 
temperature range again.

2. REASONS FOR DIFFERENT BATTERY 
PACK WORKING TIMES

Charging time problems, having not used a battery pack for 
a prolonged time will reduce the battery pack working time. 
This can be corrected after several charge and discharge 
operations by charging & working with your drill. Heavy 
working conditions such as large screws into hard wood will 
use up the battery pack energy faster than lighter working 
conditions. Do not re-charge your battery pack below 0

o

C 

and above 30

o

C as this will affect performance.

MAINTENANCE

Remove the battery pack from the tool 
before carrying out any adjustment, 
servicing or maintenance.

Your power tool requires no additional lubrication or 
maintenance. There are no user serviceable parts in your 
power tool. Never use water or chemical cleaners to clean 
your power tool. Wipe clean with a dry cloth. Always store 
your power tool in a dry place. Keep the motor ventilation 
slots clean. Keep all working controls free of dust. 
Occasionally you may see sparks through the ventilation 
slots. This is normal and will not damage your power tool.
