Motor
Your DEWALT tool is powered by a DEWALT-built motor. Be sure your power supply agrees
with the nameplate marking. Voltage decrease of more than 10% will cause loss of power and
overheating. D
EWALT tools are factory tested; if this tool does not operate, check power
supply.
COMPONENTS (FIG. 1)
WARNING: Never modify the power tool or any part of it. Damage or personal injury could
result.
A. Anvil
B. Trigger switch
C. Side handle
D. Brush inspection cap
Switch (Fig. 1)
The switch (B) in this machine functions as a motor switch and a rotational direction selector
switch. The lower part of the switch, marked with an R (right) will run the motor clock wise to
tighten a bolt. The upper part of the switch, marked L (left) will run the motor counterclockwise
to loosen the bolt. To stop the motor, release the switch.
CAUTION: Be sure to turn the switch OFF and wait until the motor comes to a complete stop
before changing direction of rotation. Switching direction of rotation while the motor is running
may cause serious damage to the tool and the operator may loose control.
ASSEMBLY
WARNING: To reduce the risk of serious personal injury, turn tool off and disconnect
tool from power source before making any adjustments or removing/installing attachments
or accessories.
Mounting a Socket (Fig. 2)
To install a socket on the anvil (A), align the hole in the side of the socket (G) with the detent
pin (E) on the anvil. Press the socket on until the detent pin engages in the hole (F). To remove
a socket, depress the detent pin through the hole, using a small, pointed object, and pull the
socket off.
Side Handle (Fig. 1)
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.
Always use side handle (C). The position of the side handle attached to the hammer case can
be changed by unscrewing the handle (right hand threads). Relocate the handle to the desired
position and reinstall.
OPERATION
WARNING: To reduce the risk of serious personal injury, turn tool off and disconnect
tool from power source before making any adjustments or removing/installing attachments
or accessories.
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.
Your impact tool generates 434 ft.-lbs. (60 kgm) output torque.
1. Place the socket on the fastener head. Keep the tool pointed straight at the fastener.
2. Press rocker 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 generator or long extension cord, 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.
Capacity
Your 3/4" (19 mm) impact wrench uses sockets with 3/4" (19 mm) square drive ends. Both sizes
of impact wrenches are capable of driving the same range of hex impact sockets available. In
particularly heavy duty usage the 3/4" (19 mm) drive impact wrench has an extra strong anvil
that will resist breakage.
MAINTENANCE
WARNING: To reduce the risk of serious personal injury, turn tool off and disconnect
tool from power source before making any adjustments or removing/installing attachments
or accessories.
Cleaning
WARNING: Never use solvents or other harsh chemicals for cleaning the non-metallic parts
of the tool. These chemicals may weaken the plastic materials used in these parts. Use a cloth
dampened only with water and mild soap. Never let any liquid get inside the tool; never immerse
any part of the tool into a liquid.
Motor Brushes (Fig. 1)
Be sure tool is unplugged before inspecting brushes. Carbon brushes should be regularly
inspected for wear. To inspect brushes, unscrew the plastic brush inspection caps (D, located
in the sides of the motor housing) and withdraw the spring and brush assemblies from the tool.
Keep brushes clean and sliding freely in their guides. Carbon brushes have varying symbols
stamped into them, and if the brush is worn down to the line closest to the spring, it must be
replaced. New brush assemblies are available at authorized D
EWALT service centers.
Lubrication
Your tool was properly lubricated before leaving the factory. In from two to six months,
depending upon use, take or send your tool to a D
EWALT certified service organization for a
complete cleaning, inspection and relubrication.
Tools used constantly on production or heavy duty jobs or exposed to heat may require more
frequent lubrication. Tools “out of service” for long periods should be relubricated before being
put back into service.

WARNING: Since accessories, other than those offered by DEWALT, have not been tested
with this product, use of such accessories with this tool could be hazardous. To reduce the risk
of injury, only DEWALT, recommended accessories should be used with this product.

Règles générales de sécurité concernant
les outils à piles
AVERTISSEMENT : Lire toutes ces directives. Tout manquement aux directives
suivantes pose des risques de choc électrique, d’incendie et/ou de blessure
grave. Le terme « outil électrique » dans tous les avertissements ci-après se rapporte
à votre outil électrique à alimentation sur secteur (avec fil) ou par piles (sans fil).
CONSERVER CES DIRECTIVES
1) SÉCURITÉ - AIRE DE TRAVAIL
a) Maintenir l’aire de travail propre et bien éclairée. Les lieux encombrés ou sombres sont
propices aux accidents.
b) Ne pas faire fonctionner un outil électrique dans une atmosphère explosive, en
présence par exemple de poussières, gaz ou liquides inflammables. Les outils élec-
triques peuvent engendrer des étincelles qui pourraient enflammer toute émanation ou
poussière ambiante.
c) Tenir les enfants, ou toute autre personne, éloignés pendant l’utilisation d’un outil
électrique. Toute distraction pourrait vous faire perdre la maîtrise de ce dernier.
2) SÉCURITÉ – ÉLECTRICITÉ
a) La fiche électrique de l’outil doit correspondre à la prise murale. Ne jamais
modifier la fiche en aucune façon. Ne jamais utiliser de fiche d’adaptation avec un
outil électrique mis à la terre. L’utilisation de fiches d’origine et de prises appropriées
réduira les risques de choc électrique.
b) Éviter tout contact corporel avec des éléments mis à la terre comme tuyaux,
radiateurs, cuisinières ou réfrigérateurs. Les risques de choc électrique augmentent
lorsque le corps est mis à la terre.
