operation of the machine should be your top

priority.

Read each procedure thoroughly. This

machine, use signal words to identify

the following:

Safety alert symbol—used to

alert personnel to potential

personal injury hazards. Obey

all safety messages that follow

this symbol to avoid possible

injury or death.

Indicates a imminently

hazardous situation which, if

not avoided, will result in death

or serious injury.

Indicates a potentially

hazardous situation which, if

not avoided, could result in

death or serious injury.

Indicates a potentially

hazardous situation which, if

not avoided, may cause minor

or moderate injury.

Indicates a potentially

hazardous situation which, if

not avoided, may result in

property damage.

Be sure to wear protective eye wear

and other protective clothing if the

situation warrants it.

Be aware of potential crushing

hazards such as moving parts, free

swinging or unsecured components

when lifting or placing loads. Always

wear approved steel-toed shoes.

Workplace Safety

Any person working on or around a machine

must be aware of all known safety hazards.

Personal safety and the continued safe

operation of the machine should be your top

priority.

Be sure to keep sparks, flames and

lighted tobacco away from flammable

and combustible materials like battery

gases and engine fuels. Always have

an approved fire extinguisher within

easy reach.

areas are properly maintained and

ready for use. Keep work surfaces

clean and free of debris that could get

other lifting or supporting device is

fully capable of supporting and

stabilizing the weight to be lifted. Use

only chains or straps that are in good

condition and of ample capacity.

Be sure that fasteners intended for

one time use (i.e., cotter pins and self-

components may fail if they are used

a second time.

Be sure to properly dispose of old oil

or other fluids. Use an approved

container. Please be environmentally

safe.

Be sure that your workshop or work

area is properly ventilated and well lit.
