WARNING Familiarize yourself with Oper-
ating/Safety instructions (man-
ual) for Skilsaw SPT79A. The manual for SPT79A
contains additional information that is not covered
in this manual. If the SPT79A manual is missing,

WARNING
Some dust created by power
sanding, sawing, grinding, drill-
ing and other construction activities contains
chemicals known to the State of California to
cause cancer, birth defects or other reproductive
harm. Some examples of these chemicals are:
–Lead from lead-based paints,
–Crystalline silica from bricks and cement and
other masonry products, and
–Arsenic and chromium from chemically-
treated lumber.
Your risk from these exposures varies, depending
on how often you do this type of work. To reduce
your exposure to these chemicals: work in a
well-ventilated area, and work with approved
safety equipment, such as those dust masks that
are specially designed to lter out microscopic
particles.

This attachment allows SKILSAW SPT79A Medusaw™ walk behind saw to function as an early
entry concrete saw and is designed for residential and light commercial projects. Early entry saw
controls random cracking of the concrete by making early contraction cuts, often within 1 – 2 hours
after the nishing process is complete. The combination of the spring-loaded skid plate and the early
entry diamond wheel specically designed for this application, allows early entry sawing while min-
imizing chipping and spalling of the cut edges.
Intended Use
WARNING
For your own safety, never
connect the saw to a power
outlet until all assembly steps are completed
and until you have read and understood the
entire instruction manual.
TOOLS REQUIRED: A screwdriver that accepts
standard 1/4" hexagonal bits is required to use
the T25 torx bit.
Separate all parts from the packing materials and
check each one against the “Loose Parts List" to
make sure that all items are accounted for before
discarding any packing material.
WARNING If any parts are missing, do
not attempt to assemble the
early entry attachment until the missing parts
are obtained and are installed correctly.

ATTACHING THE EARLY ENTRY
DIAMOND WHEEL
CAUTION
Use only SKILSAW early
entry diamond wheel with
this attachment. Using other wheels will lead to
unsatisfactory results and possible damage to
the tool or work area.
1. Tip the tool back with the guard facing up.
2. Press the lock button (on the back of the
saw) and turn the wheel bolt using the 1/2”
slot of the wrench (included with the saw and
stored in the foot of the saw) until the lock
button engages. The shaft is now locked.
Continue to depress button, turn wrench
clockwise and remove the wheel bolt and
OUTER WASHER (Fig. 3).
3. Make sure that the arrow on the diamond
wheel is pointing in the same direction as the
arrow on the guard.
4. Slide the diamond wheel into the guard and
mount it against the INNER WASHER on the
shaft. Be sure that the large diameter of the
INNER and OUTER washers lay flush
against the diamond wheel.
5. Reinstall the OUTER WASHER. First tighten
the wheel bolt nger tight, then tighten the
wheel bolt 1/8 turn (45˚) with the wrench pro-
vided. Do not use wrenches with longer han-
dles, since it may lead to over tightening of
the wheel bolt.
NOTE: Install a new skid plate every time a new
early entry diamond wheel is installed. SKILSAW
set SPT5008-EA includes 1 (one) replacement
wheel and 1 (one) replacement skid plate.
