Lower Blade Guard - DeWalt DCS577 Manual De Instrucciones

8. Depress the spindle lock button
saw spindle with the blade wrench provided until the
blade lock engages and the blade stops rotating. Using
the blade wrench, firmly tighten blade clamping screw.
NOTICE: Never engage the blade lock while saw is
running, or engage in an effort to stop the tool. Never
turn the saw on while the blade lock is engaged.
Serious damage to your saw will result.
To Replace the Blade (Fig. A, O, P)
1. Depress the spindle lock button
saw spindle with the blade wrench provided until the
blade lock engages and the blade stops rotating.
2. With the blade wrench provided, loosen the blade
clamping screw 19 by turning it clockwise as indicated
by the arrow on the outer clamp washer
3. Remove the outer clamp washer
4. Using the lower blade guard retracting lever
retract the lower blade guard. Remove used blade and
properly discard.
5. Install new blade as previously described.
6. Clean any sawdust that may have accumulated in
the guard or clamp washer area. Check the condition
and operation of the lower blade guard as previously
outlined. Do not lubricate this area.
7. Select the proper blade for the application (refer to
Blades). Always use blades that are the correct size
[7–1/4" (184 mm) diameter] with the proper size and
shape center hole for mounting on the saw spindle.
Always assure that the maximum recommended speed
(rpm) on the saw blade meets or exceeds the speed
(rpm) of the saw.

Lower Blade Guard


WARNING: The lower blade guard is a safety
feature which reduces the risk of serious personal
injury. Never use the saw if the lower guard is
missing, damaged, misassembled or not working
properly. Do not rely on the lower blade guard
to protect you under all circumstances. Your
safety depends on following all warnings and
precautions as well as proper operation of the
saw. Check lower guard for proper closing before
each use as outlined in Safety Instructions for All
Saws. If the lower blade guard is missing or not
working properly, have the saw serviced before
using. To assure product safety and reliability,
repair, maintenance and adjustment should be
performed by an authorized service center or
other qualified service organization, always using
identical replacement parts.
Blades

WARNING: To minimize the risk of eye injury, always
use eye protection. Carbide is a hard but brittle
material. Foreign objects in the work piece such as wire
or nails can cause tips to crack or break. Only operate
saw when proper saw blade guard is in place. Mount
blade securely in proper rotation before using, and
always use a clean, sharp blade.

WARNING: Do not cut metal, masonry, glass,
masonry‑type planking, cement board, tile or plastic
with this saw.
Do not use abrasive wheels or blades. A dull blade will cause
slow, inefficient cutting resulting in overload to the saw
motor, excessive splintering and could increase the possibility
of kickback. Please refer to the following table to determine
the correct size replacement blade for your model saw.

Kickback
Kickback is a sudden reaction to a pinched, bound or
misaligned saw blade, causing an uncontrolled saw to lift
up and out of the workpiece toward the operator. When the
blade is pinched or bound tightly by the kerf closing down,
the blade stalls and the motor reaction drives the unit rapidly
back toward the operator. If the blade becomes twisted or
misaligned in the cut, the teeth at the back edge of the blade
can dig into the top surface of the wood causing the blade to
climb out of the kerf and jump back toward the operator.
Kickback is more likely to occur when any of the following
conditions exists.
1. IMpRopER WoRKpIECE SUppoRT
a. Sagging or improper lifting of the cut off piece can
cause pinching of the blade and lead to kickback.
b. Cutting through material supported at the outer ends
only can cause kickback. As the material weakens it
sags, closing down the kerf and pinching the blade.
c. Cutting off a cantilevered or overhanging piece of
material from the bottom up in a vertical direction
can cause kickback. The falling cut off piece can pinch
the blade.
d. Cutting off long narrow strips (as in ripping) can cause
kickback. The cut off strip can sag or twist closing the
kerf and pinching the blade.
e. Snagging the lower guard on a surface below the
material being cut momentarily reduces operator
control. The saw can lift partially out of the cut
increasing the chance of blade twist.
2. IMpRopER DEpTH oF CUT SETTINg oN SaW
a. To make the most efficient cut, the blade should
protrude only far enough to expose one‑half of a
tooth. This allows the shoe to support the blade and
minimizes twisting and pinching in the material. See
the section titled Cutting Depth Adjustment.
