TROUBLE

 

SHOOTING

Although your new cordless grass trimmer 
is really easy to operate. If you do 
experience problems, check the following:

If grass trimmer will not operate

l

 Check battery pack assembly

l

 Charge the battery: running of the grass 

trimmer is dependent upon sufficient 
charge in the battery pack. The battery 
charge will deplete if not used for a long 
period of time. Try recharging the 
battery pack. Ensure that the battery 
pack is fully contacted charger base.  

Note:

 The battery pack will only fit into the 

charger with + to + and - to -. The charger 
will not operate at extremes of temperature. 
The charger will get warm during charging 
but this is normal.

If the battery will not charge

Check to see if the battery is properly 
inserted the charger base, and make sure 
the indicator light is on, if not check the 
mains supply. 

If the trimmer is not cutting properly

Check the condition of the cutting head, if 
the cutting line is too short or cutting head 
damaged. 

Note: do not use damaged 

cutting head.
