WARNING: Failure to comply with the following warnings could result

in serious bodily injury or death!

SAFETY WARNINGS

PERSONAL SAFETY

• Read and understand instructions before operating saw.

• Always wear safety approved hearing, eye, head and

respiratory protection.

• Wear boots with non-slip soles to provide proper footing.

Steel-toed safety boots are recommended.

• Wear rubber work gloves to avoid contact with wet

concrete which can cause serious skin irritation.

• Know how to stop the saw quickly in case of emergency.

• Keep all parts of your body away from blade and other

moving parts. Do not wear loose clothing or jewelry
which can be caught in moving parts. Wear protective
hair covering to contain long hair.

• Use caution when loading and unloading saw.

• Stay alert. Maintain awareness of saw operation. Use

common sense. Do not operate saw when tired or after
consumption of any substance that would impair physical
function or rational judgment.

• Do not over reach. Keep proper footing and balance.

• Guard against electric shock. Prevent body contact with

grounded surfaces such pipes, conduit, radiators, etc.

WORK AREA SAFETY

• Never operate the saw in any application or job where you

are not trained or supervised.

• Keep visitors, children and animals out of the work area.

• Do not operate the saw in areas of combustible material or

fumes. Sparks may occur from the saw that could cause a
fire or explosion.

• The motor and saw can become hot during operation.

Keep all body parts and foreign material away from the
saw while running.

• Avoid dangerous environments. Do not use the saw in

damp or wet locations. Do not expose saw to rain. Keep
work area well lit and clean.

• Use only extension cords suitable for outdoor use and

marked with a suffix W-A or W.

• Before connecting the saw to a power source (receptacle,

outlet, etc.) insure the voltage supplied is the same as that
specified on the saw nameplate. A power source with
voltage greater than specified on the saw can result in
serious injury as well as damage to the saw. If in doubt,
do not use the saw. Using a power source with voltage
less than the saw nameplate is harmful to the motor.

• The saw must be plugged into an outlet properly installed

and grounded in accordance with all codes. Never modify
the plug in any way. Do not use adaptor plugs. Check
with a qualified electrician if you are in doubt.

SAW SAFETY

• Do not leave saw unattended while the motor is running.

• Do not alter the saw. Any alteration or modification is

misuse and may result in a dangerous condition.

• All safety guards must be in place before starting saw.

• Only operate the saw from behind the machine with both

hands on the handle.

• Do not use damaged equipment, blades, gu ards or

personal protection equipment. Do not disable safety
equipment or kill switches.

• Use only Soff-Cut International, Inc. replacement parts.

Use of unauthorized parts may create a danger.

• Remove all wrenches from the saw before starting.

• Never stand on the saw.

• When the saw is not in use or transporting, remove the

blade and properly secure the saw to prevent accidental
movement.

• Disconnect the electric cord to the saw and put the safety

switch in off (red) position when not in use, before
servicing, and when changing or installing blades.

• Do not abuse the electric cord. Never carry the saw by

the cord or yank it to disconnect from the receptacle.
Keep cord from heat, oil, or sharp edges. Inspect cord
periodically and do not use saw if damaged.

BLADE SAFETY

• Examine cutting blades before each use. Do not use any

blade that has cracks, nicks, or flaws. Tri-arbor hole
should be undamaged. Use only dry cut, steel centered,
tri-arbor diamond blades made for cutting green concrete.

• Soff-Cut International, Inc. diamond blades are designed

to only cut green concrete. Cutting any other material
may result in blade failure or a dangerous condition.

• Inspect blade flanges for damage, excessive wear and

cleanliness before mounting the blade. The blade should
fit snugly on clean, undamaged, tri-arbor shaft.

• Use only Soff-Cut blades or blades marked with a

maximum operating speed greater than 7000 rpm.

• Never operate the saw without the blade guard assembly

securely in place including blade cover, front diverter and
skid plate installed in working order. A damaged blade
guard assembly must be replaced to protect the operator.

• Make sure the blade does not make contact with the

ground or any other surface when maneuvering the saw.

• Avoid contacting the blade while it is rotating.

• Do not force, jam or twist the blade while cutting.

GROUNDING INSTRUCTIONS

Grounding of the X-390 electric saw is necessary while in use to protect the operator from electric shock or electrocution. The
saw is equipped with an approved three-conductor cord and a three-prong grounding type plug to fit the proper grounding type
receptacle. Do not remove the grounding prong from the three-prong plug. The green or green and yellow conductor in the cord
is the grounding wire. The green wire in the cord must be the only wire connected to the saw’s grounding system and must never
be attached to an electrically “live” terminal. The saw must be plugged into an appropriate outlet that is properly installed and
grounded in accordance with all codes and ordinances. WARNING: Do not remove or modify the plug installed on the saw.

Check with a qualified electrician if you are in doubt if the outlet is properly grounded. Do not use the saw if the cord or
plug is damaged.

EXTENSION CORDS

The X-390 electric saw requires three wire extension cords only. The cord should have the required three wire receptacle to
accept the saw plug and have a three-prong grounding type plug. As the distance from the supply outlet increases, a heavier
gauge extension cord must be used. Using extension cords with too small a gauge of wire causes a serious drop in voltage
resulting in loss of power and possible saw damage. Refer to the table shown to determine the required wire gauge. The smaller
the gauge number of the wire, the greater the capacity of the cord. For example, a 14 gauge cord can carry a higher amp load than
a 16 gauge cord.

RECOMMENDED MINIMUM WIRE GAUGE

FOR EXTENSION CORDS

120 V 15 A 25’ 50’ 100’ 150’

Minimum Wire Gauge 16 AWG 12 AWG 10 AWG 8 AWG

Volts Amps Cord length in feet

GENERATORS

The minimum generator required to power the X-390 electric saw is 2800 watts continuous with a 120 volt 20 amp outlet
producing 60 hertz single phase power. Generators vary widely so contact your generator distributor or manufacturer for their
recommendation.
