INTENDED USE
These drills/drivers/hammerdrills are designed for professional drilling,
percussion drilling and screwdriving applications.
DO NOT use under wet conditions or in presence of flammable liquids
or gases.
These drills/drivers/hammerdrills are professional power tools. DO
NOT let children come into contact with the tool. Supervision is
required when inexperienced operators use this tool.
Variable Speed Trigger Switch (Fig. 2)
To turn the tool on, squeeze the trigger switch (A). To turn the tool
off, release the trigger switch. Your tool is equipped with a brake. The
chuck will stop as soon as the trigger switch is fully released.
NOTE: Continuous use in variable speed range is not recommended.
It may damage the switch and should be avoided.
Side Handle (Fig. 2)
WARNING: To reduce the risk of personal injury, ALWAYS operate
the tool with the side handle properly installed. Failure to do so may
result in the side handle slipping during tool operation and subsequent
loss of control. Hold tool with both hands to maximize control.
Side handle (G) clamps to the front of the gear case and may be rotated
360° to permit right- or left-hand use. Side handle must be tightened
sufficiently to resist the twisting action of the tool if the accessory binds
or stalls. Be sure to grip the side handle at the far end to control the tool
during a stall.
If model is not equipped with side handle, grip drill with one hand on
the handle and one hand on the battery pack.
NOTE: Side handle comes equipped on both models.
Forward/Reverse Control Button (Fig. 2)
A forward/reverse control button (B) determines the direction of the
tool and also serves as a lock-off button.
To select forward rotation, release the trigger switch and depress the
for ward/re verse control button on the right side of the tool.
To select reverse, release the trigger switch and depress the forward/
reverse control button on the left side of the tool.
The center position of the control button locks the tool in the OFF
position. When changing the position of the control button, be sure
the trigger is released.
NOTE: The first time the tool is run after changing the direction of
rotation, you may hear a click on start up. This is normal and does not
indicate a problem.
Torque Adjustment Collar/Electronic
Clutch (Fig. 3–5)
Your tool has an electronic adjustable torque screwdriver system for
driving and removing a wide array of fasteners. Circling the torque
adjustment collar (E) are numbers, a drill bit symbol, and in some
models, a hammer symbol. These numbers are used to set the clutch
to deliver a torque range. The higher the number on the collar, the
higher the torque and the larger the fastener that can be driven. To
select any of the numbers, rotate until the desired number aligns with
the arrow.
WARNING: When the torque adjustment collar is in the drill or
hammerdrill positions, the drill will not clutch. The drill may stall if
overloaded, causing a sudden twist.
