Miter Gauge Adjustment - DeWalt DW744 Manual De Instrucciones

MITER GAUGE ADJUSTMENT

Your miter gauge features adjustable stops at 90° and 45°
left and right. To adjust these stops, loosen the lock nuts and
tighten or loosen the three adjusting screws against the stop
plate (Fig. 21).
FENCE PARALLEL ADJUSTMENT
1. Unlock rail lock lever.
2. Locate rear pinion bearing and loosen the two hex bolts
just enough to allow side-to-side movement.
3. Adjust fence parallel to blade.
4. Lock rail lock lever and check parallel alignment of the
blade.
5. Tighten the 2 hex bolts that secure the rear pinion bear-
ing assembly to the table.
NOTE: If there is not enough travel in the pinion bearing
assembly to allow the fence to be parallel to the blade,
take the unit to an authorized service center.
RACK AND PINION MESH ADJUSTMENT
Proper adjustment of the rack and pinion mesh is done at
the factory. If it should become necessary to adjust the rack
and pinion mesh, use the following procedure.
1. Turn the saw upside down and locate the front pinion
bearing.
2. Using a narrow blade screw driver or #20 torx driver,
access the screw through the slot. Loosen the screw
(counterclockwise) until the head touches the inside of
the bearing box.
3. Tighten the screw (clockwise) 3/4 of a turn.
4. Repeat procedure for rear pinion bearing.
Saw Blades
THIS SAW IS INTENDED FOR THE USE OF SAW BLADES
10" IN DIAMETER OR SMALLER
1. The saw blade furnished with your new saw is a 10"
(254mm) combination blade, used for cross cutting
(across the grain) and ripping (with the grain) through
the material. The center hole to fit on the arbor is 5/8"
(16mm) diameter. This blade will produce a good quality
cut for most applications.
2. There are many types of blades available to do specific
and special jobs such as cross cut only, rip only, hollow
ground, thin plywood, paneling, etc.
3. Use only saw blades designed for maximum safe oper-
ating speeds of 5,000 RPM or greater.
4. Saw blades should always be kept sharp. It is recom-
mended that you locate a reputable sharpening service
to sharpen your blades when needed.
5. Never stack blades on top of one another to store. Place
material such as cardboard between them to keep the
blades from coming in contact with one another.
CAUTION: Abrasive wheels should not be used on this
saw.
Kickback
Kickback is a dangerous condition! It is caused by the
workpiece binding against the blade. The result is that the
workpiece can move rapidly in a direction opposite to the
feed direction. During kickback, the workpiece could be
thrown back at the operator. It can also drag the operator's
hand back into the blade if the operator's hand is at the rear
of the blade. If kickback occurs, turn the saw OFF and verify
the proper functioning of the splitter, anti-kickback teeth and
guards before resuming work.
WARNING:
• Always use the guard and make certain it is in good
working order. The guard's splitter helps prevent binding
and the anti-kickback teeth on each side of the splitter
minimize the possibility of kickback. Use extra cau-
tion until the workpiece is through the splitter and has
engaged anti-kickback teeth.
• Do not saw warped, bowed or cupped wood. The work-
piece must have one straight, smooth side to go against
the rip fence or miter gauge. The workpiece must sit flat
on the table without rocking.
• Do not cut "freehand". Always use either the rip fence or
the miter gauge. Never use both.
• Use extra care when the guard assembly cannot be
used (during dadoing or molding).
• Support large workpieces carefully. Allowing them to
sag or droop can cause kickback.
OPERATION
WARNING: Before using the saw, verify the following
each and every time:
• ALWAYS wear proper eye, hearing and respiratory
equipment.
• Blade is tight.
• Bevel angle and height lock knobs are tight.
• If ripping, ensure fence lock lever is tight and fence is
parallel to the blade.
• If crosscutting, miter gauge knob is tight.
• The blade guard is properly attached and the anti-kick-
back teeth are functioning.
• ALWAYS inspect the guard and splitter for proper align-
ment operation and clearance with saw blade.
Failure to adhere to these common safety rules can greatly
increase the likelihood of injury.
WARNING: To reduce the risk of injury, turn unit off
and disconnect machine from power source before
installing and removing accessories, before adjusting or
changing set-ups or when making repairs. An accidental
start-up can cause injury.
9
WARNING: Before connecting the table saw to the power
source or operating the saw, always inspect the guard and
splitter for proper operation alignment and clearance with
saw blade. Personal injury may result.
WARNING: Ripping or crosscutting may cause saw to tip
over while operating. Make sure saw is securely mounted
to a stable surface.
WARNING: Never use the fence and miter gauge
together. This may cause a kickback condition and injure
the operator.
CAUTION: If your saw makes an unfamiliar noise or if it
vibrates excessively, cease operating immediately until the
source has been located and the problem corrected.
CAUTION: The proper throat plate must be in place at
all times to reduce the risk of a thrown work piece and
possible injury.
There are two basic types of cutting with table saws: rip-
ping and crosscutting. Cutting with the grain is ripping and
cutting against the grain is crosscutting. With manmade
materials, the distinction is made such that ripping is cut-
ting to a different width and crosscutting describes cutting
material across the shorter dimension.
WARNING: When ripping, always use the fence to pro-
vide a guide for the material and guard against a kickback
situation.
CAUTION: When crosscutting, always use the miter
gauge.
Ripping
WARNING: Never touch the "free end" of the work piece
or a "free piece" that is cut off, while the power is ON and/
or the saw blade is rotating. Piece may contact the blade
resulting in a thrown work piece of possible injury.
WARNING: A rip fence should ALWAYS be used for rip-
ping operations to prevent loss of control and personal inju-
ry. NEVER perform a ripping operation freehand. ALWAYS
lock the fence to the rail.
WARNING: When bevel ripping and whenever possible,
place the fence on the side of the blade so that the blade
is tilted away from the fence and hands. Keep hands clear
of the blade and use a push stick to feed the work piece if
there is less than 6" (152 mm) between the fence and the
blade.
1. Lock the rip fence by pressing the rail lock lever down.
Remove the miter gauge.
2. Raise the blade so it is about 1/8" (3.2 mm) higher than
the top of the work piece.
3. Hold the work piece flat on the table and against the
fence. Keep the work piece about 1" (25.4 mm) away
from the blade.
