4. Read the warning labels on the metal saw.
Before Each Use
1. Inspect your saw. If any part of this metal
saw is missing, or bent, or has failed in any
way, or any electrical parts do not work
properly, turn the saw off and unplug the
saw. Replace damaged, missing, or failed
parts before using the saw again.
2. Plan your work to protect your eyes, hands,
face and ears.
A. Wear safety goggles (not glasses) that
comply with DIN 58214 (show on
package). Using any power tool can
result in foreign objects being thrown
into the eyes, which can result in
permanent eye damage. Goggles are
available at stores. Use of glasses or
use of goggles not in compliance with
DIN 58214 could result in severe injury
from breakage of the eye protection.
B. For dusty operations, wear a face
shield along with safety goggles.
C. To avoid injury from jams, slips or
thrown piece:
˙ It is important to choose the right
blade for the material and the type
of cutting you plan to do. This saw
is equipped with a bi-metallic
blade which can be used to cut
stainless steel, steel, iron, brass,
aluminum, wood, plastic and so
on.
˙ Make sure the direction of rotation
arrow on the blade matches the
direction arrow on the saw. The
blade teeth should always point
downward at the front of the saw.
˙ Make sure the blade is sharp,
undamaged and properly aligned.
With the saw unplugged, push the
power-head all the way down.
Head spin the blade and check for
clearance. If the blade hits
anything, make the adjustments
shown in the Maintaining
Maximum Cutting Capacity
section.
˙ Make sure the blade and arbor
collars are clean.
˙ Make sure all clamps and locks
are tight and there is no excessive
play in any parts.
˙ Never cut freehand:
a. Brace your work piece solidly
against the fence and table top so
it will not rock or twist during the
cut. Make sure no debris is caught
beneath the work piece.
b. Make sure no gaps between the
work piece, fence and table will let
the work piece shift after it is cut in
two.
c. Use jigs, fixture or a different tool
for unstable work pieces.
˙ Never cut more than one work
piece at a time.
˙ Make sure the cut-off piece can
move sideways after it is cut off.
Otherwise, it could get wedged
against the blade and thrown
violently.
˙ Make sure bystanders are clear of
the tool and work piece. Keep
them clear of the area behind the
saw where debris will be thrown.
˙ Never turn your metal saw “ON”
before clearing everything except
the work piece and related support
devices off the table.
D. To avoid risk of hearing damage, wear
ear plugs or muffs during extended
period of operation.
E. To avoid being suddenly pulled into the
blade:
˙ Do not wear gloves.
˙ Remove all jewelry and loose
clothing.
˙ Tie back long hair.
˙ Roll long sleeves above the elbow.

F. To avoid injury from accidental starting,
always unplug saw before
disconnecting the guard, installing or
removing any blade, accessory or
attachment, or making any adjustment.
G. To avoid an electrical shock, make
sure your fingers do not touch the
metal prongs on the plug when
inserting or removing the plug to or
from a live outlet.
H. Never put lubricants on the blade while
it is spinning.
I. To avoid burns or other fire damage,
never use the saw near flammable
liquids, vapors or gases.
J. To avoid injury from unsafe
accessories use only accessories
shown on the recommended
accessories list in this manual.
Whenever Saw is Running
WARNING: Do not allow familiarity (gained
from frequent use of your metal saw) to
cause a careless mistake. Always
remember that a careless fraction of a
second is enough to cause a severe injury.
1. Before actually cutting with the saw, let it
run for a while. If your saw makes an
unfamiliar noise or if it vibrates excessively,
stop immediately. Turn the saw off. Unplug
the saw. Do not restart until finding and
correcting the problem.
2. Never confine the piece being cut out.
Never hold it, clamp it, touch it, or use
length stops against it. It must be free to
move sideways. If confined, it could get
wedged against the blade and thrown
violently.
3. Avoid awkward hand positions where a
sudden slip could cause a hand to move
into the blade.
4. Let the blade reach full speed before
cutting.
5. Feed the saw into the work piece only fast
enough to let the blade cut without bogging
down or binding.
6. Before freeing jammed material, turn the
switch off and unplug the saw. Wait for all
moving parts to stop.
7. After finishing a cut, keep holding the power
head down, release the switch, and wait for
all moving parts to stop before moving your
hands.
WARNING:
Read the following warning labels found on
the front of the saw.
DANGER
˙ Keep hands out of saw blade path.
˙ Never cut anything freehand.
˙ Never reach behind or beneath blade.
˙ To avoid electric shock, do not expose to
rain.

DANGER: To avoid electric shock
1. Do not change the power cord and
plug to another specification not
provided by the manufacturer.
2. Do not use in rain or where floor is
wet. This tool is intended for indoor
residential use only.
Motor Safety Protection
CAUTION: To avoid motor damage, this
motor should be blown out or vacuumed
frequently to keep sawdust from
interfering with normal motor ventilation.
1. Connect this tool with a fuse or circuit
breaker. Using the wrong size fuse can
damage the motor.
2. If the motor does not start, press the stop
button down immediately. UNPLUG THE
TOOL. Check the saw blade to make sure
it turns freely. If the blade is free, try to start
the motor again.
3. If the motor still does not start that have to
check the motor’s carbon brushes which
can be used 600~800 hours if carbon
brushes has been worn, please change the
new one.
4. If the motor suddenly stalls while cutting
material, press the stop button off, unplug
the tool, and free the blade from the steel
Then you may restart the motor and finish
the cut.
5. Fuses may “blow” or circuit breakers may
trip frequently if:
a. Motor is overloaded-overloading can
occur if you feed too rapidly or make
too many start/stops in a short time.
b. Voltage not more than 10% above or
below the nameplate voltage can
handle normal loads. For heavy loads,
however, the voltage (caused by a
small size wire in the supply circuit or
an overly long supply circuit wire) may
drop too low for the motor to operate.
Always check the connections, the
load and the supply circuit whenever
motor does not work well. Check wire
sizes and length with the Wire Size
Chart below.
6. Most motor troubles may be trace to loose
or incorrect connections, overload, low
voltage (such as small size wire in the
supply circuit) or to overly long supply
circuit wire. Always check the connections,
the load and the supply circuit whenever
motor doesn’t work well. Check wire size
and length with the Wire Size Chart below.
Wire Sizes
The use of any extension cable will cause some
loss of power. To keep this to a minimum and to
prevent overheating and motor burn-out, use the
table below to determine the minimum wire size
(lead cross-section) of an extension cable.
For circuits that are more than 40m away from
the electrical service box, the wire size must be
increased proportionately in order to deliver
ample voltage to the saw motor.
