Operating Instructions

using the button located on the top of the
handle.)

that provides the best grip.
• To operate the trigger, depress the trigger lock
button on the left side of the tool above the
trigger; (See Figure 1) and then depress the
trigger to start the saw.

light pressure moving forward through the cut.
Cutting Edge Saw™ Routine Maintenance
• Always unplug the saw from the electric outlet
before attempting any maintenance.
• Clean the entire unit occasionally by removing
dust, debris and oils.
• Occasionally remove the bottom plate; remove
any cutting chips that remain lodged in the area
where the cutting blade rotates.
• Remove and inspect the cutting blade for
material residue. This should be done after 4-8
hours of use.
• Most material cutting debris will be expelled
through the chip exhaust area and into the
Cutting Chip Catch Bag. It is recommended that
the Cutting Chip Catch bag be emptied when it
becomes2/3fullofcuttingdebrisandmaterials.
Blade Replacement
The standard blade (RB-BNCE-45) for the BNCE-
45 Cutting Edge Saw™ should be replaced when
the blade is dull or visibly worn, or when there is a
noticeabledecreaseincuttingeciency.
To change the Blade:
• Unplug the saw before performing any work
on the tool blade.
• Using the smaller Allen key tool, remove the
four (4) screws that hold the Blade Cover to the
body of the saw. See Figure 2
• Remove the cover, being careful to set the four
mounting screws and the accompanying locking
nuts aside in a safe place.
• Presstheblade/spindlelockbuttontosecure
the blade spindle (See Figure 1). You may need
to manually rotate the blade so that the lock
button engages and is secured in a locked
position.
• When the blade is locked, use the larger Allen
key to remove the blade mounting screw and
blade locking head at the center of the blade
(Figure 3). Note: With the blade spindle locked,
you will need to rotate the screw in a counter-
clockwise direction.
• Make sure that when the blade is removed, that
the blade head is free of any metal debris that
has not escaped the tool. As needed, clean the
tool to remove any metal chips or particles from
the blade head area.
• Install the new blade over the spindle at the
center opening. BN Products-USA™ blades will
be marked “This Side Up” to ensure that the
blade is not installed upside-down. In addition,
each blade is printed with a directional arrow
(Figure 3). This arrow must always point in the
same direction as the arrow marked on the top
side of the blade cover, as shown in Figure 4.
• Replace the blade locking head using the blade
mounting screw, using the Allen key to securely
tighten the screw in a clockwise direction. DO
NOT OVERTIGHTEN.
• Replace the blade cover using the four (4)
mounting screws, making sure that the locking
nuts are still inserted in the threaded hole for
each mounting screw. Securely fasten each
screw without overtightening.
See Figures 2, 3, and 4 on the next page.
Follow this same procedure when installing a
specialty blade, such as the RB-BNCE-45S Strut
Cutting Blade (sold separately). Always save the
Allen key tools with the saw in a safe place for
future use.
