WARNING: To reduce the risk of serious personal
injury, turn tool off and disconnect battery pack
before making any adjustments or removing/
installing attachments or accessories. An accidental
start-up can cause injury.
Proper Hand Position (Fig. A, E)
WARNING:
To reduce the risk of serious personal injury,
ALWAYS use proper hand position as shown.
WARNING:
To reduce the risk of serious personal
injury, ALWAYS hold securely in anticipation of a
sudden reaction.
Proper hand position requires one hand on the main handle 8 .
Variable Speed Trigger Switch (Fig. A)
To turn the tool on, squeeze the trigger switch 1 . To turn
the tool off, release the trigger switch. Your tool is equipped
with a brake. The chuck will stop when the trigger switch is
fully released.
The variable speed switch enables you to start the application at
a slow speed. The further you squeeze the trigger, the faster the
tool will operate. For maximum tool life, use variable speed only
for starting holes or fasteners.
nOTE: Continuous use in variable speed range is not
recommended. It may damage the switch and should
be avoided.
Forward/Reverse Control Button (Fig. A)
A forward/reverse control button 2 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 forward/reverse control button on the right side of
the tool.
To select reverse, 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.
Worklights (Fig. A)
There are three worklights 7 located around the anvil 9 or
the chuck collar 3 . The worklights will be activated when the
trigger switch is squeezed.
nOTE:
The worklights are for lighting the immediate work
surface and are not intended to be used as a flashlight.
Quick-Release Chuck (Fig. A, D)
DCF815
nOTE: The chuck accepts 6.35 mm hex accessories and
25.4 mm bit tips only. Using 25.4 mm bits allows better access
in tight spaces.
Place the forward/reverse button
2 in the locked off (center)
position or remove battery pack before changing accessories.
To install an accessory
, push accessory to fully insert into
chuck 4 . The chuck collar 3 does not need to be pulled up to
lock accessory in place.
To remove an accessory , pull the chuck collar 3 away
from the front of the tool. Remove the accessory and release
the collar.
Usage
Your impact tool generates the following output torque:
CAT # FT.-lBs. in.-lBs. nM
DCF815 79 950 107
CAUTION:
Ensure fastener and/or system will withstand
the level of torque generated by the tool. Excessive torque
may cause breakage and possible personal injury.
1. Place the socket on the fastener head. Keep the tool pointed
straight at the fastener.
2. Press switch to start operation. Always check torque with a
torque wrench, as the fastening torque is affected by many
factors including the following:
- Voltage: Low voltage, due to a nearly discharged
battery, will reduce fastening torque.
- socket size: Failure to use the correct socket size will
cause a reduction in fastening torque.
- Bolt size: Larger bolt diameters generally require
higher fastening torque. Fastening torque will also vary
according to length, grade, and torque coefficient.
-
Bolt: Ensure that all threads are free of rust and other
debris to allow proper fastening torque.
- Material: The type of material and surface finish of the
material will affect fastening torque.
- Fastening Time: Longer fasten ing time results in
increased fastening torque. Using a longer fastening
time than recom mended could cause the fasteners to
be overstressed, stripped or damaged.
