Turn the dial 7 to the desired level. Turn the dial upwards for higher
speed and downwards for lower speed. The required setting is a matter of
experience, e.g.
• when chiselling or drilling in soft, brittle materials or when minimum
break-out is required, set the dial to a low setting;
• when breaking or drilling in harder materials, set the dial to a
high setting.

• Clutch Setting 40 Nm
is designed to easily clutch out when the drill bit encounters re-bar or
other foreign substances.
• Clutch Setting 80 Nm
such as core-bits and deep hole drilling and is designed to clutch out at
a higher torque threshold.
nOTE: If it is not possible to select position 80 Nm, run the unit under load
and try again.
Each time the tool is plugged in, it will automatically default to clutch
setting 1 into clutch setting 40 Nm
