Electrical
Power Supply and Motor
Specifications
The AC motor used in this saw is a universal,
nonreversible type (see Motor in the Specifica-tions sect ion on page 8).
To avoid electrical hazards,
fire hazards, or damage to the machine, use
proper circuit protection. Your saw is wired
at the f actory for 120V operation. Conne ct t o
a 120V, 15 Amp circuit and use a 15 amp time
delay fuse or circuit br eaker. If pow er cord is
worn or cut , or damaged in any w ay, have it
replaced immediat ely to avoi d shock or f ire.
Elect ri cal Requirements
This machine is double insulated to provide a
double thickness of insulatio n between the user
and t he machine's electrical system. All e xposed
metal part s are isolated f rom the internal metal
motor components with protective insulation.
This saw has a plug that looks like the one
shown in Figure A.
Extension Cords
Make sure your extension cord is in good
condition. When using an extension cord, be
sure to use one heavy enough to carry the
current yo ur machi ne will draw . An under sized
cord will cause a drop in the line voltage
resulting in power loss and overheating. The
table below shows the correct size to use
depending on the cord length and nameplate
ampere rati ng. If in doubt, use the next heavier
gauge. Remember, the smaller the gauge
number, the heavier the cord.
Cord Length AWG 00 – 25ft 016 25 – 50ft 014
Important: Make certain the receptacle in
question is properly grounded. If you are not
sure, have a registered electrician check the
receptacle.
Figure A
To reduce the risk of electrical shock, this saw
has a polarized plug (one blade is wider t han t he
other). This pl ug will fit i n a polari zed outlet o nly
one way; if the plug does not fit fully in the outlet,
rever se the pl ug. I f it st ill does not fit, contact a
qualified electrician to install the proper outlet.
Do not change the plug in a ny way.
Double insulation does not take the place of
normal safety precautions when operating this
tool.
To avoid electrocution:
1. Use only identical replacement parts when
servicing a tool with double insulation.
Servicing should be perf or med by a q ualified
technician.
2. Do not use power tools in wet or damp
locations or expose t hem to rain or snow.

Auxi l iary Wood Fence
When making multiple or r epetitive cuts that result
in cut-off pieces of one inch or less, it is possible for
the saw blade to catc h the cut-off piece and t hrow it
out of t he saw or into the bl ade guard and housing,
possibly causing damage or injury. To minimize
this, an auxiliary wood fence can be mounted to
your saw. Holes are provided in the saw fence to
attach an auxiliary wood fence (this provides
additional depth of cut). This fence should be
constructed of straight wood approximately 3/4 in.
thick by 1-1/2 in. high by 22 in. long. Attach the
wood fence sec urely a nd mak e a full dept h cut to

Cutt i ng Base Mo lding
Base moldings and many other moldings can be
cut on a compound miter saw. The setup of the
saw depends on molding characteristics and
applicatio n. Perf or m pract ice cuts on scrap mat er ial
to achieve best results:
1. Always make sure moldi ngs rest f irmly against
fence and table. Use hold-dow n, crown molding
vise or C-clamps, whenever possible, and
place tape o n the area bei ng clamped to avoid
marks.
2. Reduce splintering by t api ng the cut area prior
to making the cut. Mark the cut line directly on
the tape.
3. Splintering typically happens due to an
incorrect blade applicatio n a nd t hinness of t he
material.
Note: Always perform a dry run cut so you can
determine if the operation being attempted is
possible before power is applied to t he saw.
Cr own Molding
Your compound miter saw is suited for the difficult
task of cutting crown molding. To fit properly, cr own
molding must be compound-mitered with extreme
accuracy. The two surfaces on a piece of crown
molding t hat fit flat ag ainst t he ceil ing a nd wall are
at angles t hat, when added toge ther, equal exactly
90°.
Most crown molding has a top rear angle (the
section that fit s flat against t he ceiling) of 52°a nd a
bottom rear angle (t he sec tion that fits f lat against
the wall) of 38°.
In order to accurately c ut crown moldi ng f or a 90°
inside or outside corner, lay the molding with its
broad back surface flat on the saw table.
When setting the bevel and miter angles for
compound miters, remember that the settings are
interdependent; changing one changes the other,
as well.

To avoid injury while
performing maintenance, always unplug the
power cord before working on the saw.
Failure to comply may cause ser ious injury!
Never use gasoline or any
highly volatile solvents to clean the miter
saw. Failure to comply may cause serious
injury!
Use only replacement parts
that are identi cal to the part s list at the end
of this manual and r eassemble exactly as t he
original assembly to avoid electrical shock.
Failure to comply may cause ser ious injury!
Replacing Carbon Brushes
Replace both carbon brushes when either has
less than 1/4 i n. le ngt h of car bon r emaining, or if
the spring or wire is damaged or burned.
To inspect or r eplace brushes:
1. Unplug the saw.
2. Remove t he black plastic cap on t he side of
the motor
Remove the cap cautiously, because it is
spring-loaded.
Lo wer Blade G uard
Do not use the saw without the lower blade
guard. The lower blade g uard is att ached to t he
saw for your protection. Should the lower guard
become damaged, do not use the saw until the
damaged guard has been replaced. Develop a
regular check to make sure the lower guard is
working properly. Clean the lower guard of any
dust or buildup with a damp cloth.
When cleaning the lower
guard, unplug the saw from the power
source receptacle to avoid unexpected
startup.
Do not use solvents on the
guard. They could make the plastic “ clo udy ” and
brittle.
Saw Dust
Perio dica lly, sa w d ust will a cc um ulate und er t he
work table and base. This could cause diffic ulty
in the mo veme nt of the wor ktable when sett ing
up a miter cut. Frequently blow out or vacuum
up the saw dust.
If blowing saw dust, wear
proper eye protection to keep debris from
entering eyes.
3. Pull out the brush and replace.
4. Reverse above steps to reassemble.
Tighten the cap snugly, but do not overtighten.
Replace the br ush f or the other side in t he sa me
manner described above.
Note: To reinstall the same brushes, first make
sure the brushes go back in the way they came
out. This will avoid a break-in period that
reduces motor perfor ma nce and increases w ear .
Lubrication
All the motor beari ngs in t his tool ar e l ubricated
with a suffic ient amount of high gr ade lubricant
for the life of the unit under normal operating
conditions; therefore, no further lubrication is
required.
Lubricate t he following as necessary:
Chop pivot: Apply light machine oil.
Central pivot of plastic guard: Use light
household oil (sew ing mac hine oil) o n metal-tometal or metal-t o-plastic g uard contact areas as
required for smooth, quiet operation. Avoid
excessi ve oil, to which saw dust will cling.
