Porter-Cable 617 - Replacement Parts; Extension Cord Selection

CAUTION: Blades coast after turned off.
4. SUPPORT LARGE PANELS. Large panels must be supported, as
shown in Fig. 10, to minimize the risk of blade pinching and kickback.
When cutting operation requires the resting of the saw on the workpiece,
the saw shall be rested on the larger portion and the smaller portion
cut off.
5. USE RIP FENCE. Always use a fence or straight edge guide when
ripping.
6. GUARD AGAINST KICKBACK. Kickback occurs when the blade
is pinched and the saw is driven back towards the operator. Keep body
to side of blade. Stay alert and maintain firm grip on saw for control.
Release switch immediately if blade binds or saw stalls. Keep blades
sharp. Support panels as shown in Fig. 10. Use fence or straight edge
guide when ripping. DO NOT force tool. DO NOT remove saw from
work during a cut while blade is moving.
7. LOWER GUARD. Raise lower guard with the retracting handle when
pocket cutting.
8. ADJUSTMENTS. Before cutting be sure depth and bevel adjust¬
ments are tight.
9. USE ONLY CORRECT BLADES IN MOUNTING. Do not use blades
with incorrect size holes. Never use defective or incorrect blades, washers
or bolts.
10. AVOID CUTTING NAILS AND KNOTS. Inspect for and remove
all nails from lumber before cutting. Try to layout cuts between knots.
REPLACEMENT PARTS
When servicing, use only identical replacement parts.
MOTOR
Many Porter-Cable tools will operate on either D.C., or single phase
25 to 60 cycle A.C. current and voltage within plus or minus 5 percent
of that shown on the specification plate on the tool. Several models,
however, are designed for A.C. current only. Refer to the specification
plate on your tool for proper voltage and current rating.
CAUTION: Do not operate your tool on a current on which the
voltage is not within correct limits. Do not operate tools rated A.C.
only on D.C. current. To do so may seriously damage the tool.
EXTENSION CORD SELECTION
If an extension cord is used, make sure the conductor size is large
enough to prevent excessive voltage drop which will cause loss of power
and possible motor damage. A table of recommended extension cord
sizes will be found below. This table is based on limiting line voltage
drop to 5 volts (10 volts for 230 volts) at 150% of rated amperes.
If an extension cord is to be used outdoors it must be marked with
the suffix W-A following the cord type designation. For example —
SJTW-A to indicate it is acceptable for outdoor use.
