Lower Blade Guard - DeWalt DW934 Manual De Instrucciones

2. Retract the lower blade guard (G) and place blade on saw
spindle against the inner clamp washer, making sure that the
blade will rotate in the proper direction (the direction of the
rotation arrow on the saw blade and the teeth must point in the
same direction as the direction of rotation arrow on the saw). Do
not assume that the printing on the blade will always be facing
you when properly installed. When retracting the lower blade
guard to install the blade, check the condition and operation of
the lower blade guard to assure that it is working properly. Make
sure it moves freely and does not touch the blade or any other
part, in all angles and depths of cut.
3. Place outer clamp washer (N) on saw spindle with the large flat
surface against the blade with beveled side facing out.
4. Thread blade clamping screw (F) into saw spindle by
hand (screw has left-hand threads and must be turned
counterclockwise to tighten).
5. Depress the blade lock (D) while turning the saw spindle with
the blade wrench until the blade lock engages and the blade
stops rotating (Fig. 9).
6. Tighten the blade clamping
screw firmly with the blade
wrench.
NOTE: 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.

use blades that are the correct size (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.
