Speed selection
Your tool is equipped with a speed selector that allows you to
select a speed and torque according to the application:
• Press the switch until the speed selector LED light turns on
• Press the speed selector button.
• The green LED light will indicate the selected level
• Press the button until the desired level is reached.
Screwing
Speed (RPM) / Max. Torque (lb-ft)
Level 3 0 - 2 700 RPM / 221 Ib-ft - 300 Nm
Level 2 0 - 2 100 RPM / 184 Ib-ft - 250 Nm
Level 1 0 - 1 800 RPM / 162 Ib-ft - 220 Nm
Turn On and operation control
• Press the switch to start operation. Release the switch to
stop the operation.
• The switch allows selecting the adequate speed for each
job. The more you push the switch the fastest the hammer
drill will run.
Screwing - Unscrewing
Consider the following points as the tightening torque can
be affected by each of them:
• Voltage: Low voltage from a nearly completely discharged
battery or battery will reduce the tightening torque.
• Accessory size: Failure to use the correct accessory size
will cause a reduction in tightening torque. - Bolt size:
Larger diameter bolts generally require greater fastening
torque. Locking torque will also vary according to length,
grade and torque coefficient.
• Bolt: Make sure all threads are free of rust and other
debris to allow for proper tightening torque.
• Material: The type of material and surface finish of the
material will affect the tightening torque.
• Tightening time: Longer tightening time increases the
tightening torque. Longer than recommended tightening
time may put too much stress on the fasteners or cause
them to roll or become damaged.
