Safety warnings for

drills and hammer drills

Right way to operate the hammer drill.

Wrong way to operate the hammer drill.

       • Choose the right bit for the work piece. 

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

• To drill concrete or stone, use bits specifically designed 

for concrete.

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

encompass a minimum of 0.03” (0.04” 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

• Before starting to work with the drill, take a few minutes 

to assess the job to be done and double-check all the 

safety caution rules.

         • Fit the bit into the chuck. Remove the 

chuck wrench before drilling. Failure to follow this 

instruction shoots out the chuck wrench with great speed 

and cause severe injury.

     • Before drilling walls, floors or ceiling, 

look for any built-in objects, like power cables and 

conductors or pipes.

     • Verify the switch is in the OFF position 

(See page 7 Operation and control) before connecting the 

drill. Otherwise, it can unexpectedly start operating and 

could cause sever injuries.

       • Turn off and disconnect the tool before 

reversing the chuck’s direction as well as fitting or replacing 

bits.

WARNING

DANGER

DANGER

Choose the right bit

• Use the auxiliary handles, if supplied with the tool. 

Loss of control may result in personal injury.

• Hold the tool by the isolated parts. The cutting part of 

bit could come into contact with hidden wiring or

with its own power cord.

 Making contact with a

power cord causes the tool metal parts get electrified and 

may result in electric shock to the user.

• Do not force the tool to excessive workloads.

      • Turn off the hammer drill immediately 

if the bit gets stuck into de work piece. Then, remove the 

bit off the work piece. Do not try removing stuck bits 

turning on and off the tool.

• Do not apply too much force on the tool in order to 

accelerate the drilling procedure. The bit could get 

damaged and the tool would loose efficiency and useful 

life.

         • A large diameter bit causes a higher 

reactive force leading to losing control over the tool.   To 

avoid this possibility, firmly hold the tool with both hands 

and keep balanced footing. Drill at 90°

• Be prepared to relax the drilling force when the bit goes 

through the material. Sudden movements could break the bit 

or damage the hammer drill.

       • Do not touch the bit or the orifices 

immediately after drilling. Wait until they cool down to 

handle them. Do not try to cool them down using water 

or oil.

• Immediately after using do not set the tool where there 

are particles and / or dust. They can be absorbed into the 

tool mechanism and cause damage.

• Use earplugs when using the hammer drill.

Exposure to noise can cause hearing loss.

• Use dust mask and dust extractor if necessary. 

Remember that materials such as asbestos, paint with 

lead, additives, some types of wood, metals or minerals 

are highly toxic.

• Use safety glasses.
