reversing lever to the left (when viewed from the chuck end). To position the lever for forward
operation, turn the hammerdrill OFF and push the lever to the right.
Hammer/Drill Selector (Fig. 2)
To switch the tool from the drilling mode to the hammering mode (or vice-versa) rotate the dial
(D) on the applicable symbol. For straight drilling, align the drill bit symbol toward the chuck. For
hammering, align the hammer symbol with the lever, as shown in the figure.
NOTE: The selector must be in either drill, or hammer/drill mode at all times. There are no
operable positions between the two.
Chuck Removal (Fig. 3, 4)
1. Open the chuck jaws as far as possible.
2. Insert a screwdriver into the chuck and remove the chuck retaining screw by turning
clockwise.
3. Tighten an Allen key into the chuck and strike it with a hammer as shown.
Operation
DRILLING
1. Always unplug the drill when attaching or changing bits or accessories.
2. Use sharp drill bits only. For WOOD, use the twist drill bits, spade bits, power auger bits, or
hole saws. For METAL, use the steel twist drill bits or hole saws. For MASONRY, such as
brick, cement, cinder block, etc., use carbide-tipped bits rated for percussion drilling.
3. Be sure the material to be drilled is anchored or clamped firmly. If drilling thin material, use
a wood "back-up" block to prevent damage to the material.
4. Always apply pressure in a straight line with the bit. Use enough pressure to keep drill bit-
ing, but do not push hard enough to stall the motor or deflect the bit.
5. Hold tool firmly to control the twisting action of the drill.
6. IF DRILL STALLS, it is usually because it is being overloaded or improperly used.
RELEASE TRIGGER IMMEDIATELY, remove drill bit from work, and determine cause of
stalling. DO NOT CLICK TRIGGER OFF AND ON IN AN ATTEMPT TO START A
STALLED DRILL — THIS CAN DAMAGE THE DRILL.
7. To minimize stalling or breaking through the material, reduce pressure on drill and ease the
bit through the last fractional part of the hole.
8. Keep the motor running when pulling the bit back out of a drilled hole. This will help prevent
jamming.
9. With variable speed drills there is no need to center punch the point to be drilled. Use a slow
speed to start the hole and accelerate by squeezing the trigger harder when the hole is deep
enough to drill without the bit skipping out.

DRILLING IN METAL
Start drilling with slow speed and increase to full power while applying firm pressure on the tool.
A smooth even flow of metal chips indicates the proper drilling rate. Use a cutting lubricant when
drilling metals. The exceptions are cast iron and brass which should be drilled dry. The cutting
lubricants that work best are sulphurized cutting oil or lard oil; bacon-grease will also serve the
purpose.
NOTE: Large (5/16" to 1/2") holes in steel can be made easier if a pilot hole (5/32" to 3/16") is
drilled first.
DRILLING IN WOOD
Start drilling with slow speed and increase to full power while applying firm pressure on the tool.
Holes in wood can be made with the same twist drills used for metal. These bits may overheat
unless pulled out frequently to clear chips from the flutes. Work that is apt to splinter should be
backed up with a block of wood.
DRILLING IN MASONRY
When drilling in masonry, use carbide tipped bits rated for percussion drilling and be certain that
the bit is sharp. Ensure that the hammer mode is selected. Use a constant and firm force on the
tool to drill most effectively. A smooth, even flow of dust indicates the proper drilling rate.
Depth Rod (Fig. 5)
To adjust the depth rod (F), loosen the side handle (E) and move rod so that the distance
between the end of the rod and the end of the bit equals the desired drilling depth. Tighten the
side handle. When drilling with depth rod, stop when end of rod reaches surface of material.
Maintenance

Use only mild soap and damp cloth to clean the tool. Never let any liquid get inside the tool;
never immerse any part of the tool into a liquid.
Self-lubricating bearings are used in the tool and periodic relubrication is not required. In the
unlikely event that service is ever needed, take your tool to an authorized service location.

Règles de sécurité – Généralités
AVERTISSEMENT! LIRE ET COMPRENDRE TOUTES LES DIRECTIVES, car le non-
respect des directives suivantes peut entraîner un choc électrique, un incendie ou des
blessures graves.
CONSERVER CES DIRECTIVES
ZONE DE TRAVAIL
• Garder la zone de travail propre et bien éclairée; les établis encombrés et les endroits
sombres sont propices aux accidents.
• Ne pas utiliser les outils électriques dans une atmosphère explosive, comme à prox-
imité de liquides, de gaz ou de poussières inflammables; le moteur peut créer des étincelles
et enflammer les vapeurs ou les poussières environnantes.
• Tenir les enfants, les visiteurs ou toute autre personne à l'écart lorsqu'on utilise un
outil électrique; les distractions peuvent faire perdre la maîtrise de ce dernier.
MESURES DE SÉCURITÉ - ÉLECTRICITÉ
• Les outils mis à la terre doivent être branchés dans une prise bien installée et mise à
la terre conformément à tous les codes et règlements en vigueur. Ne jamais retirer la
broche de terre ni modifier la fiche. Ne pas utiliser d'adaptateur. Vérifier auprès d'un
électricien qualifié en cas de doute quant à la mise à la terre de la prise. En cas de défail-
lance électrique ou de bris de l'outil, la mise à la terre procure un chemin de faible résistance
au courant qui autrement traverserait l'utilisateur. Cette protection ne s'applique qu'aux out-
ils de classe I (mis à la terre).
• Les outils à double isolation sont munis d'une fiche polarisée (c'est-à-dire que l'une des
lames est plus large que l'autre), laquelle ne peut être raccordée qu'à une prise polarisée et
ce, dans un seul sens; on doit l'inverser si on est incapable de l'enfoncer complètement. Si
la fiche ne s'adapte toujours pas, on doit demander à un électricien qualifié d'installer la prise
appropriée. On ne doit jamais modifier la fiche. La double isolation élimine le besoin d'in-
