Precautions on using SDS hammer drill. 
 

1/ Before using the SDS hammer drill always 

make sure the oil supply is full and the screw 

is tight. 

 

2/ The handle must always be attached to the 

drill before operation takes place. Always 

Place the handle on the side that suits the job 

in hand, do not use the drill without the 

handle as this could invite injuries.  

 

3/ Safe operation, always make sure you 

have a stable posture and safe footing before 

operating the SDS drill. 

 

4/ When working at a high level, always 

make sure that no person or persons are 

under you, as this could invite injuries to 

those persons under you. 

 

5/ Before starting any job like breaking, 

chipping a wall, floor or ceiling, thoroughly 

confirm that no items such as an electric 

cable, water  pipe or conduit are buried inside 

as this could cause injury or flooding.
