ROBERTS 10-56 LONGNECK PLUS 6" JAMB SAW INSTRUCTIONS
ASSEMBLY AND BLADE CHANGING
1. Make sure the saw is unplugged.
2. Insert the blade clamp into the saw blade arbor hole,
so the blade clamp is securely seated in the blade.
* Make sure the blade teeth are facing the direction of rotation
(counterclockwise viewed from the bottom).
3. Insert the blade retainer screw, with the saw blade
centered, into the saw arbor shaft. When the screw
is finger tight, check that the blade is centered and
fully seated.
4. Depress the black arbor lock knob on the top of the saw
motor head to engage and lock the arbor.
5. Using the Allen® wrench , turn the blade screw clockwise
until the blade clamp is tight on the shaft.
6. Insert masonry blade adaptor prior to installing the masonry blade. Repeat steps 1 through 5.
7. Attach the plastic handle, using the two 3/8" diameter bolts. Put the lock washers between
the outside of the handle and under the bolt head. Tighten both bolts with the
open end wrench provided. Make sure the handle is secure before using the
Roberts 10-56 LONGNECK PLUS 6" Jamb Saw.
OPERATING THE ROBERTS 10-56 LONGNECK PLUS 6" JAMB SAW
1. Make sure you have read all safety instructions before operating.
2. Make sure the saw is unplugged. Make sure the safety guard and handle are
attached securely, and that you are wearing protective goggles.
3. Check for nails, screws, masonry or other hard material in the area you want to
cut. Remove all such material and debris from the cutting area.
4. Determine the amount of material you need to remove from the bottom of the jamb and
draw a scribe line on the door jamb.
5. Loosen the two wing nuts on the adjustment skirt.
a. Set the base of the adjustment skirt on the floor and adjust the saw so the TOP of the
blade is even with the scribe mark on the jamb. You can also measure the distance
from the floor to your scribe line with a ruler, then set the Roberts 10-56 LONGNECK
PLUS 6" Jamb Saw height against the ruler. Remember to measure to the top of the
saw blade.
b. Tighten the wing nuts enough to hold the adjustment skirt firmly in the saw body.
c. Check the inside of the adjustment skirt to make sure the saw body is parallel to the
index lines inside the skirt. This step is important to prevent "binding" of the blade
against the material you are cutting.
d. If the adjustment skirt is parallel, tighten the wing nuts securely.
e. Double check your saw height adjustment against the scribe mark on your work.
f. DO NOT allow the blade to contact the floor or substrate material. This can damage the
blade, and the floor, and place excess loads on the motor.
6. Set the depth guide by loosening the screw knob on the adjustment tab. Set the depth guide
to allow the saw blade to cut the depth needed to just CLEAR your jamb or base molding.
a. Deeper cuts will cause damage to plaster or wall board, and will create excessive
dust. This will also cause excessive wear to your saw blade.
b. Plaster dust will cause excess wear to the gears and bearings in the power unit.
7. To reduce dust, attach vacuum hose to vacuum part. Turn vacuum on.
8. Plug the electrical cord into a 120V outlet or extension cord. Place the saw on the floor.
9. Grasp the saw firmly and push the saw into the wood and move
the saw parallel to the to the floor to cut the jamb.
10. Limit the depth of your cut to the thickness of the base material
to minimize the chance of hitting nails, drywall, plaster, etc.
11. For your safety, and to comply with safety regulations,
the switch on the Roberts 10-56 LONGNECK PLUS 6" Jamb
Saw DOES NOT LOCK in the "on" position. The motor
will turn off when the switch is released.
