GASOLINE/PROPANE POWERED EQUIPMENT

• Engine exhaust from this product contains

chemicals known to the State of California to
cause cancer, birth defects or other reproduc­tive harm.

• Gasoline is extremely fl ammable and poisonous.

It should only be dispensed in well ventilated areas,
and with a cool engine.

• Small gasoline engines produce high concentra-

tions of carbon monoxide (CO) example: a 5 HP 4 cycle
engine operation in an enclosed 100,000 cu. ft. area with
only one change of air per hour is capable of providing
deadly concentrations of CO in less than fi fteen minutes.
Five changes of air in the same area will produce noxious
fumes in less than 30 minutes. Gasoline or propane pow­ ered equipment should not be used in enclosed or partially
enclosed areas. Symptoms of CO poisoning include, head­ ache, nausea, weakness, dizziness, visual problems and
loss of consciousness. If symptoms occur - get into fresh
air and seek medical attention immediately.

ELECTRICAL POWERED EQUIPMENT

Extreme care must be taken when operating electric
models with water present: Ensure power cord is prop­erly grounded, is attached to a Ground-Fault-Interrupter
(GFI) outlet, and is undamaged.

• Check all electrical cables - be sure connections are tight and

cable is continuous and in good condition. Be sure cable is

correctly rated for both the operating current and voltage of

this equipment.

• Improper connection of the equipment-grounding conductor can

result in a risk of electric shock. Check with qualifi ed electri-

cian or service person if there is any doubt as to whether the

outlet is properly grounded. Adhere to all local codes and

ordinances.

• NOTE: In the event of a malfunction or breakdown, grounding

provides a path of least resistance for the electric current to
dissipate. The motor is equipped with a grounded plug and
must be connected to an outlet that is properly installed and
properly grounded. DO NOT modify the plug provided on the
motor. If the plug does not fi t the outlet have a qualifi ed electri-
cian install the proper receptacle.

• Switch motor OFF before disconnecting power.

• Do not disconnect power by pulling cord. To disconnect, grasp

the plug, not the cord.

• Unplug power cord at the machine when not in use and before

servicing.

GENERAL INSTRUCTIONS

good physical condition and mental health (not fatigued). The
operator and maintenance personnel must be physically able
to handle the bulk weight and power of this equipment.

• This is a one person tool. Maintain a safe operating distance
to other personnel. It is the operators’ responsibility to keep

other people (workers, pedestrians, bystanders, etc.) away
during operation. Block off the work area in all directions with
roping, safety netting, etc. for a safe distance. Failure to do so
may result in others being injured by fl ying debris or exposing
them to harmful dust and noise.

• This equipment is intended for commercial use only.

• For the operator’s safety and the safety of others, always keep

all guards in place during operation.

• Never let equipment run unattended.

• Personal Protection Equipment and proper safety attire must

be worn when operating this machinery. The operator must
wear approved safety equipment appropriate for the job such
as hard hat and safety shoes when conditions require. Hear­ing protection MUST be used (operational noise levels of this
equipment may exceed 90db). Eye protection MUST be worn
at all times.

Keep body parts and loose clothing away from moving
parts. Failure to do so could result in dismemberment
or death.

• Do not modify the machine.

• Stop motor/engine when adjusting or servicing this equipment.

Maintain a safe operating distance from fl ammable
materials. Sparks from the cutting-action of this machine
can ignite fl ammable materials or vapors.

DUST WARNING

Some dust created by power sanding, sawing,
grinding, drilling, and other construction activi­ties contains chemicals known to cause cancer,
birth defects, or other reproductive harm. Some
examples of these chemicals are:

• Lead from lead-based paints, and

• Crystalline silica from bricks and concrete and other

masonry products.
Your risk of exposure to these chemicals varies depending

on how often you do this type of work. To reduce your risk:
work in a well ventilated area, use a dust control system, such
as an industrial-style vacuum, and wear approved personal
safety equipment, such as a dust/particle respirator designed
to fi lter out microscopic particles.

Read and understand this Operator’s Instruction Manual,

and the Engine Manufacturer’s Owner’s Manual

before operating this equipment.

Death of serious injury can result if this machine is used improperly.

Safety Guidelines

Eye and ear protection must be worn at all times while the saw is in use. During normal
operation, sound pressure levels exceed 92dBA. Use only ANSI approved safety glasses
to help prevent eye injury. Standard eyeglasses have only impact resistant lenses; they are
NOT safety glasses.

Operator must wear appropriate clothing and footwear. Do not wear loose clothing or jewelry
that can get tangled in moving parts. Footwear should provide sure footing and protection
from debris that may be dropped. Take steps to insure hair will not be caught in moving parts.
If necessary, tie it back.

• When loading or unloading the saw, use caution. Make sure rolling table is locked so that the blade will not be
damaged. Do not move the saw while the engine is running.

• Never exceed the maximum operating speed of the blade. Match the blade speed rating with the arbor shaft
speed.

• Never leave the saw running unattended.

• Never operate this saw under the infl uence of drugs, alcohol or when taking medications that impair the senses or
reactions, or when excessively tired or under stress.

• Do not lend or rent this equipment without including the Operator’s Instruction Manual and the Engine Manufac­ turer’s Manual.

• Make sure all safety decals can be clearly read and understood. Replace damaged or missing decals immedi­ ately.

For Electric Models:

• Electric motor must be properly grounded at all times. Check the outlet box to be sure the electrical service is
properly grounded and that adequate power is available. Insuffi cient power will cause motor to overheat and burn
out. Use only grounded extension cords correctly sized for the current draw and voltage drop (amp rating and
length). Never use frayed, damaged, taped or underrated extension cords. Electrical shock could result in death
or serious injury and damage to the equipment.

Dry cutting creates a large volume of airborne dust. For health reasons, the operator should wear
an applicable respirator. The dust may contain chemicals known to cause serious illnesses, in­cluding Silicosis - a fatal disease of the lungs. Check the chemical properties of the material to be
cut and follow all EPA/OSHA regulations.

Safety warnings and guidelines do not by themselves eliminate danger.

They are not substitutes for proper accident prevention procedures and good judgement.

1.4 Service Safety

OPERATIONS

Poorly maintained equipment can become a safety hazard! In order for the equipment to operate safely and
properly over a long period of time, periodic maintenance and occasional repairs are necessary.

Warning

DO NOT attempt to clean or service machine while it is running. Rotating parts can cause servere

injury.

DO NOT crank a fowled engine with the spark plug removed on gasoline-powered engines. Fuel

trapped in the cylinder will squirt out of the spark plug hole.

DO NOT test for spark on gasoline-powered engines if engine is fl ooded or the smell of gasoline is

present. A stray spark could ignite fumes.

DO NOT use gasoline or other types of fuels or fl ammable solvents to clean parts, especially in en-

closed areas. Fumes from fuels and solvents can become explosive.

ALWAYS operate machine with all safety devices and guards in place and in working order.

ALWAYS keep area around muffl er free of debris such as leaves, paper, cartons, etc. A hot muffl er

could ignite them, starting a fi re.
