Safety Warnings for

Hammer drills / Drills / Drivers

                         • Use only the                      charger 

included to charge the battery. Using a different charger 

may cause fire or injury hazard.

                         • Use only batteries specifically designed 

for the tool. Different batteries could generate risk of injury 

or fire.

                         • Do not use the charger outdoors.

• When charging, obey the “+/-“ polarity.

• Never recharge a leaking battery or that is visibly 

damaged.

• Do not use batteries or a charger for purposes different 

that it was designed for.

• Do not modify the battery contacts or the chargers.

-  Never expose the batteries to higher than 122 °F 

temperatures or direct sun light.

                         • Never expose the batteries to fire or 

impact. They could explode.

                          • Batteries shall be kept away from 

metallic objects like clips, coins, keys, nails, screws or other 

type of object making contact with the terminals. It would 

cause a short circuit and burns or fire. They should be kept 

clean, dry and in good repair.

                          • Under extreme conditions the battery 

liquid could spill out. Avoid any contact. If an accidental 

contact happens clean with enough water. If the battery 

liquid comes into contact with your eyes, clean with 

enough water and immediately go see the doctor. Liquid 

expelled from the batteries could cause irritation or burns.

• Remove battery when not in use.

                          • If the battery will be stored for long 

periods of time, keep an intermediate charge (40%) to 

maximize its useful life. Do not leave it completely charged 

for long periods of time, or leave it charging when not in 

use.

• Keep batteries away from children reach.

• Do not discard batteries together with household trash.  

Go to a specialized center for it’s recycling. 

Battery and Charger

• Take your time to assess the job to be done and double 

check you are paying attention to the necessary caution 

advices before starting to drill.

• Adjust correctly the bit into the chuck.

     • Before boring a wall, floor or ceiling, 

double check there are no hidden objects, like cables, 

power conductors or pipes.

     • Verify the switch is in the OFF position 

before inserting the battery. Otherwise it will start working 

unexpectedly, causing severe injuries.

      • Turn off and disconnect the tool before 

reversing the chuck rotation direction, as well as setting up 

or replacing a bit.

Before operating the tool

• Hold the tool by it’s isolated surfaces designed for that 

purpose, especially when making jobs where the bit might 

contact hidden wiring. Contact with a power cable makes 

the metallic parts of the tool will be energized as well and 

produce a short circuit to the operator.

• Do not submit the tool to excessive loads.

       • If the bit gets stuck in the work piece, 

turn off the tool immediately. Then, remove the bit from 

the work piece. Do not try to remove stuck bits turning on 

and off the tool.

• Do not put excessive pressure on the tool to accelerate 

boring.  Otherwise the bit will get damaged and the tool 

efficiency will diminish as well as it working life.

         • The largest the bit diameter, the 

reactive force is higher. The reactive force is higher causing 

loss of control over the tool. To prevent this possibility hold 

firmly the tool with both hands, and keep good footing 

while boring at 90°.

• Stay alert and ready to relax the force when the bit goes 

through the material. Sudden movements can break the bit 

or damage the tool.

       • Do not touch the bit or the orifices 

immediately after drilling. Wait for them to cool off to 

manipulate. Do not try to cool them with water or oil.

• Before leaving the tool aside make sure all the moving 

parts have come to a complete stop.

• Avoid setting the tool where there are particles and / or 

dust immediately after use.  These can get absorbed 

inside the tool mechanism and damage the machine.

• Wear hearing protectors when making jobs

with a noise level higher than 85dB.

• Wear anti-dust mask and dust extraction equipment if 

necessary. Remember that working with materials like 

asbestos, leaded paint, additives, some types of wood, 

metals or minerals are highly toxic.

• Wear safety eyeglasses.

While operating the tool

       • Choose the right bit for the work piece. 

It reduces the risk of severe injury and makes the job easier.

• To work on metal or plastic, use bits suitable for metal. Sizes 

encompass a minimum of 0,03” (0,05” for a 0,5” chuck) and 

up to the chuck maximum capacity.

• On wood, use regular bits suitable for wood. In any case, 

to drill 0,25” or smaller orifices, use bits designed to drill 

on metal.

• Do not try using bits exceeding the chuck capacity.

Choose the right bit
