VII. USAGE SUGGESTION
1. If there isn’t enough force pushing down on the bit, the tool 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 tool 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 (41°F)
or below), the blow of the hammering mode may be weaker than normal at the
beginning stage.
This is because the grease becomes stiffer in low temperatures, increasing
friction.
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.
