DeWalt DCF836 Bersetzt Von Den Originalanweisungen Seite 39

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. 1)
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 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 centre
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. 1)
There are three worklights (G) located around the
chuck collar (C). The worklights will be activated
when the trigger switch is depressed.
When the trigger is released, the worklights will stay
illuminated for up to 20 seconds.
NOTE: The worklights are for lighting the immediate
work surface and are not intended to be used as a
flashlight.
Quick-Release Chuck (Fig. 1, 3)
WARNING: Use only impact
accessories. Non-impact accessories
may break and cause a hazardous
condition. Inspect accessory prior to use
to ensure that it con tains no cracks.
NOTE: The chuck accepts 6.35 mm (1/4") hex
accessories and 25.4 mm (1") bit tips only. Using
25.4 mm (1") bits allows better access in tight
spaces.
Place the forward/reverse button (B) in the locked
off (centre) position or remove battery pack before
changing accessories.
To install an accessory, push accessory to fully insert
into chuck (D). The chuck collar (C) does not need
to be pulled up to lock accessory in place.
To remove an accessory, pull the chuck collar away
from the front of the tool. Remove the accessory
and release the collar.
Usage
Your impact tool generates the following maximum
torque:
Cat # Nm
DCF836 155
DCF886 165
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 accessory on the fastener head.
Keep the tool pointed straight at the fastener.
2. Press switch to start operation. Release the
switch to stop 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.
• Accessory size: Failure to use the correct
accessory 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.
MAINTENANCE
Your D WALT power tool has been designed to
e
operate over a long period of time with a minimum
of maintenance. Continuous satisfactory operation
depends upon proper tool care and regular
cleaning.
