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, guards 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

Volts	Amps		Cord length in feet
120 V	15 A	25’	50’	100’	150’
Minimum Wire Gauge		16 AWG	12 AWG	10 AWG	8 AWG

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.
