OPerating instructiOns
NOTE: Before using the tool, read the instruction 
book carefully.
INTENDED USE
The machine is intended for driving in and loosening 
screws as well as for drilling in wood, metal and plastic.
BEFORE PUTTING INTO OPERATION
- BATTERY CHARGING
A battery that is new or has not been used for a longer 
period does not develop its full capacity until after 
several charging / discharging cycles.
A significantly reduced working period after charging 
indicates that the batteries are used and must be 
replaced.  
- TO REMOVE OR INSTALL BATTERY PACK (See 
Fig. A)
Depress the Battery Pack Release Button (7) to release 
and slide the Battery Pack (6) out from your tool. After 
recharge, slide it back into your tool. A simple push and 
slight pressure will be sufficient.
1. ON / OFF SWITCH (See Fig. B)
Depress On/Off Switch (9) to start and release it to 
stop your drill. The On/Off Switch is fitted with a brake 
function which stops your chuck immediately when you 
quickly release the switch. 
It is also a variable speed switch that delivers higher 
speed and torque with increased trigger pressure. 
Speed is controlled by the amount of switch trigger 
depression. 
WARNING: Do not operate for long periods 
at low speed because excess heat will be 
produced internally.
2. SWITCH LOCK (See Fig. B)
The switch trigger can be locked in the OFF position. 
This helps to reduce the possibility of accidental 
starting when not in use. To lock the switch trigger, 
place the Rotation Control (4) in the center position.
3. REVERSIBLE (See Fig. B)
For drilling and screw driving use forward rotation 
marked “  ” (lever is moved to the left). Only use 
reverse rotation marked “  ” (lever is moved to the 
right) to remove screws or release a jammed drill bit.
WARNING: Never change the direction of 
rotation when the chuck is rotating, wait 
until it has stopped!
