RIDGID MEGAMax R86403 Manual Del Operador página 7

OPERATION
 When drilling hard, smooth surfaces, use a center punch
to mark the desired hole location. This will prevent the bit
from slipping off-center as the hole is started.
 If the bit jams in the workpiece or if the tool stalls, stop
the tool immediately. Remove the bit from the workpiece
and determine the reason for jamming.
NOTE: This tool has an electric brake. When the switch trig-
ger is released, the chuck stops turning. When the brake is
functioning properly, sparks will be visible through the vent
slots on the housing. This is normal and is the action of the
brake.
NOTICE:
During extended periods of use, it is possible
that lubrication may leak from the gearbox. This
is a normal occurrence and does not indicate a
problem with the tool. Avoid placing the tool on
an unprotected surface to avoid possible property
damage.
MASONRY DRILLING
See Figure 9, page 11.
For maximum performance, use carbide-tipped masonry
impact bits when drilling holes in brick, tile, concrete, etc.
 Select Rotary Hammer Mode.
 Apply light pressure and medium speed for best results
in brick.
 Apply additional pressure for hard materials such as
concrete.
 When drilling holes in tile, practice on a scrap piece to
determine the best speed and pressure. Begin drilling at
a very low speed to prevent the bit from slipping off the
starting point.
WOOD AND METAL DRILLING
For maximum performance, use high speed steel bits for
wood or metal drilling. Select Rotational Drilling Mode.
Begin drilling at a very low speed to prevent the bit from
slipping off the starting point.

as well as a Three-year Limited Warranty. For Warranty and Policy details,

NOTICE:
When using the tool, do not apply too much
pressure. Too much pressure will place unnecessary
load on the motor.
WOOD DRILLING
 Select Rotational Drilling Mode.
 Increase the speed as the bit bites into the material.
 When drilling through holes, place a block of wood behind
the workpiece to prevent ragged or splintered edges on
the back side of the hole.
METAL AND STEEL DRILLING
 Select Rotational Drilling Mode.
 Use a light oil on the drill bit to keep it from overheating.
The oil will prolong the life of the bit and increase the
drilling action.
 Maintain a speed and pressure which allows cutting
without overheating the bit. Applying too much pressure
will:
• Overheat the tool;
• Wear the bearings;
• Bend or burn bits; and
• Produce off-center or irregular-shaped holes.
 When drilling large holes in metal, start with a small bit,
then finish with a larger bit.
CHISELING
See Figure 10, page 11.
 Select Chisel Only Mode.
 Position the tip of the chisel at the point where chiseling
is to begin.
 Apply light pressure and medium speed for best results in
brick or tile. Apply additional pressure for hard materials
such as concrete.
NOTE: For extended use, engage the trigger lock-on feature as described earlier in the manual.
 Selecting Chisel Adjust Mode allows the bit to rotate
freely to the best operating position for your chiseling
application.
