Adjusting auxiliary handle
and depth control rod
• Turn the auxiliary handle as indicated in the figure. When
the auxiliary handle mount is loose, turn it into the desired
position. Turn the auxiliary handle in a reverse direction to
fix it in the new position.
• To move the depth control rod, loosen the mount as
explained in the previous paragraph. Once loose push the
rod to the desired depth. Tighten the auxiliary handle to fix
the rod into the new position.
Wood drilling
• To make holes of 1/4" or less it is recommended to use
high speed bits. To make holes larger than 1/4", it is
recommended to use spade bits for wood.
• Turn impact-rotation selector to drill mode (
CAUTION
• Secure the workpiece to prevent it from
turning when drilling.
• Begin drilling at a very low speed to prevent the bit from
slipping off the starting point. Increase the speed as the
drill bit bites into the material.
• When drilling through the holes, place a black of wood
behind the workpiece to prevent ragged or splintered
edges on the back side of the hole.
• Release the trigger when the hammer drill may need to
be stopped suddenly.
Metal drilling
• Use high speed steel bits for metal or steel drilling.
• Move impact-rotation selector to drill mode (
• Use a center punch to mark the hole location on the
workpiece.
• Begin drilling at a very low speed to prevent the bit from
slipping off the starting point.
• Maintain speed and pressure which allows cutting
without overheating the bit.
CAUTION
Applying too much pressure or faster
speed will: overheat the drill, wear the bearings, bend or
burn bits and produce off-center or irregular shaped holes
• When drilling large holes in metal, it is recommended to
drill with a small bit at first, then finish with a larger bit.
• Lubricate the bit with oil to improve drilling action and
increase bit life.

Masonry drilling
• Use tungsten carbide-tipped masonry act bit when
drilling holes in brick, tile, concrete,etc.
• Move impact-rotation selector to hammer mode (
).
• Apply light pressure and medium speed for best results
in brick.
• Apply additional pressure and high speed for hard
materials such as concrete.
• When drilling in tile, practice on a scrap piece to
determine the best speed and pressure.
