. USAGE SUGGESTION
1. If there isn't enough force pushing down on the bit, the hammer may not be able
to blow in hammering mode.
This is to prevent the hammering mode from operating with no load. Press down
harder on the bit to engage the hammer and cause it to blow.
Always be sure to press down with enough force when working.
2. In winter or in other situations where the temperature of the unit is low (5°C or be-
low), the blow of the hammering mode may be weaker than normal at the begin-
ning stage.
This is because the grease becomes stiffer in low temperatures, increasing fric-
tion.
If this should happen, operating hammering mode with no load for approximately
30 seconds and repeat this 3 times. This will restore its blowing power.
