WORKING HINTS FOR YOUR HAMMER
If your power tool becomes over heated, set the speed to maximum and run no load for 2-3
minutes to cool the motor. SDS-plus tungsten carbide drill bits should always be used for
concrete and masonry.
When drilling in metal, only use HSS drill bits in good condition. Where possible use a
pilot hole before drilling a large diameter hole.
