CIRCLE CUTTING

1. Before attaching the rip fence, draw a circle
and drive a finishing nail in the center of circle.
2. Drill or plunge cut near the circles edge,
turn saw off and move the switch lock to the
lock position (Fig. 14).
3. Attach rip fence to saw with the edge guide
facing UP. In order for the rip fence to cut a
circle, the nail must be in alignment with the
blade, as shown in (Fig. 15).
NAIL
4. Measure the distance from the selected
hole to the blade to be equal to the circle
radius.
5. Move switch lock to the unlock position,
hold the saw firmly, squeeze trigger and
slowly push the saw forward. To make a hole,
BLADE MUST BE IN
ALIGNMENT WITH NAIL
cut from inside the circle; To make wheels or
discs, cut from the outside.
Cutting Tip: Cut slowly so the blade will stay
straight in the cut. Place small wedges in the
cut as shown in Fig. 14, to keep the inner
circle from spreading when near the end of
the cut.
RELEASING AND INSERTING
BATTERy PACK

IMPORTANT CHARGING NOTES

(NICKEL-CADMIUM BATTERIES)
1. The battery pack accepts only about 80%
of its maximum capacity with its first few
charge cycles. However, after the first few
charge cycles, the battery will charge to full
capacity.
2. The charger was designed to fast charge
the battery only when the battery
temperature is between 32˚F (0˚C) and
113˚F (45˚C).
3. A substantial drop in operating time per
charge may mean that the battery pack is
nearing the end of its life and should be
replaced.
4. If you anticipate long periods (i.e. a month
or more) of non-use of your tool, it is best to
run your tool down until it is fully discharged
before storing your battery pack. After a long
period of storage, the capacity at first recharge
will be lower. Normal capacity will be restored
in two or three charge/discharge cycles.
Remember to unplug charger during storage
period.
5. If battery does not charge properly:
a. Check for voltage at outlet by plugging
in some other electrical device.
b. Check to see if outlet is connected to a
light switch which turns power "off" when
lights are turned off.
c. Check battery pack terminals for dirt.
Clean with cotton swab if necessary.
d. If you still do not get proper charging,
take or send tool, battery pack and charger
to your local Skil Service Center.
Note: Use of charger's or battery packs not
sold by Skil will void the warranty
