Use the adjustable depth stop to obtain the
desired depth of mortar removal. The tuck-
pointer is held with the guard window facing
upward so that the user can easily see the
joint during operation.
Allow the tool to reach full speed before apply-
ing it to the workpiece surface.
Hold the tool with both hands and apply the
abrasive wheel to the mortar surface.
Diamond Wheels
Do not use water when
cutting with this tool.
The tool is not designed for water and electric
shock may occur.
If this tuckpointer is being
used as a small abrasive
cutoff machine, the tool is only approved for
cutting or scoring masonry products like:
Concrete, cinder blocks, bricks, and stone.
Use Type 41/1A dry diamond wheels for cut-
ting masonry and concrete. Dry diamond
wheels stay cooler, clog less and last longer.
1. Before running a cut-off machine, inspect
the cutting wheel for chips or cracks. Re-
place bad wheels immediately. New wheels
should be run in at no load for at least a
minute in the direction away from the pres-
ence of other people. Imperfect wheels will
normally break apart during this time.
2. An abrasive cut-off machine must NEVER
be operated without the attached guard se-
curely in place. The guard should be rotated
into the position where maximum protection
is provided for the operator from sparks and
wheel periphery.
3. Proper apparel for operating the tool in-
cludes eye protection, leather gloves and
dust mask.
4. With the tool in the “OFF” position, become
familiar with handling the tool. Control the
head of the tool with the side handle. Con-
trol the cutting edge of the wheel with the
switch handle. Always use both hands when
operating the tool.
5. Never drop the tool. Set the tool down gen-
tly, but never on the wheel.
6. CUTTING CONCRETE will throw large
amounts of dust into the surrounding area.
Protective dust masks are required for
breathing protection for the operator and
other nearby workers.
7. It is not recommended to use this tool over-
head or in any position that would not allow
proper control. Ladders are not considered
solid support structures.
8. Avoid overloading tool. Do not allow the
wheel to bind or stall. Many cuts, espe-
cially into solid concrete, require successive
passes. Do not expose any more abrasive
wheel than necessary to cut with normal
amount of pressure applied to tool. Begin
cutting from the edge of the material, only
plunging to a depth of one diamond wheel
segment. Cutting too deeply at one time
does not allow dust to clear fully and erodes
/thins body of wheel. Do not force the tool;
load it normally. Depending on material
hardness and density, make successively
deeper passes until cut is complete.
Constant Response Circuitry
The internal electronic feedback system
provides a “soft start”, which will reduce the
stresses that occur from a high torque start.
The system also helps to keep the no load
speed virtually constant between no-load and
load conditions.
Overload Protection
Your tool is equipped with overload protection
to protect the motor. If the tool stops during
operation TURN OFF SWITCH IMMEDIATE-
LY and allow the motor to cool for about 30
seconds by running at no-load. If the overload
protection stops the tool repeatedly, exces-
sive force is causing the tool to overload. Don’t
press so hard and let the tool do the work.
