Removing and Installing the Blade Guard (Saws)
NOTE:
The Model 7400 and 7400XL do not have a separate top blade guard. The blade is removed from the
backside of the saw with the two blade wrenches provided.
The blade guard is attached to the carriage with the red torque knobs (22), Figure 20 or Figure 21. Remove the
torque knobs to remove the guard. Be sure to leave the rubber washers on the torque knobs because they
prevent the knobs from slipping. Always install the blade guard before operating the saw (21).
