Saw Blades - DeWalt DW745 Manual De Instrucciones

Part A – Adjusting the Bevel Scale System (Fig. 22, 23)
1. Remove the blade guard from the saw and raise the blade all the way up in the table.
2. Unlock the bevel lock lever (J) and loosen the bevel stop screw (QQ).
3. Place a square against the table and blade.
NOTE: Be sure to place the square between the teeth on the blade to ensure an
accurate measurement.
4. Adjust the bevel angle until the blade is flat against the square. Lock the bevel lock lever
(J).
5. Move the bevel stop cam (RR) until it firmly contacts the trunnion casting. Tighten the
bevel stop screw.
6. Repeat procedure at 45˚ using a triangle or speed square.
Part B – Adjusting the Bevel Scale Pointer
NOTE: Complete this step only if Part A has been completed.
7. Check the bevel scale angle. If the pointer does not read 0°, loosen the pointer screw
(SS) and move it to the 0° mark on the bevel scale. Retighten the pointer screw.
MITER GAUGE ADJUSTMENT
(Calibrating Miter Gauge Pointer)
Your miter gauge features adjustable stops at
90° and 45° left and right.
To adjust the miter gauge, loosen the screw (TT)
and move to desired position. Tighten the screw
against the stop plate (Fig. 24).

Saw Blades

NOTE: This saw is intended for the use of saw
blades 10" in diameter or smaller.
NOTE: This saw is not intended for use with
dado blades and molding cutters. Personal
injury may occur.
1. The saw blade furnished with your new saw is a 10" (254 mm) combination blade, used
for crosscutting (across the grain) and ripping (with the grain) through the material. The
center hole to fit on the arbor is 5/8" (16 mm) diameter (.625"). 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 operating speeds of 5,000 RPM or
greater.
4. Saw blades should always be kept sharp. It is recommended that you locate a reputable
sharpening service to sharpen your blades when needed.
Kickback
Kickback is a dangerous condition! It is caused by the work piece binding against the blade.
The result is that the work piece can move rapidly in a direction opposite to the feed direc-
tion. During kickback, the work piece 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-kick-
back teeth and guards before resuming work.
WARNING:
1. 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 caution until the work piece is through the splitter
and has engaged anti-kickback teeth.

2. 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 work piece must sit flat on
the table without rocking.
3. Do not cut "freehand". Always use either the rip fence or the miter gauge. Never use
both.
4. Use extra care when the guard assembly cannot be used (during non-through cuts).
5. Support large work pieces carefully. Allowing them to sag or droop can cause kick-
back.
OPERATION
WARNING: Before using the saw, verify the following each and every time:
1. ALWAYS wear proper eye, hearing and respiratory equipment.
2. Blade is tight.
3. Bevel angle and height lock knobs are tight.
4. If ripping, ensure fence lock lever is tight and fence is parallel to the blade.
5. If crosscutting, miter gauge knob is tight.
6. The blade guard is properly attached and the anti-kickback teeth are functioning.
7. ALWAYS inspect the guard and splitter for proper alignment 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.
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: ripping 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 cutting to a different width and cross-
cutting describes cutting material across the shorter dimension.
WARNING: When ripping, always use the fence to provide 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 result-
ing in a thrown work piece of possible injury.
WARNING: A rip fence should ALWAYS be used for ripping operations to prevent loss
of control and personal injury. 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
