Operator Safety

Operating Safety

Power equipment is only as safe as the operator. If it is misused, or not properly maintained, it can be dangerous! Remember, you are responsible for your safety and that of those around you.

Use common sense, and think through what you are doing. If you are not sure that the task you are about to perform can be safely done with the equipment you have chosen, ask a professional: contact your local authorized dealer.

Read the Manual

The operator’s manual contains important safety information you need to be aware of BEFORE you operate your unit as well as DURING operation.

Safe operating techniques, an explanation of the product’s featu es and
controls, and maintenance information is included to help you get the
most out of your equipment investment.

following pages. Also completely read the Operation sec forion.
	Children
Tragic acci	ents can occur with children. Do not allow them any-
where near the area of operation. Children are often attracted to the
unit and m	wing activity. Never assume that children will remain

whe e you last saw them. If there is a risk that children may enter the area where you are mowing, have another responsible adult watch them.

Slope Operation

You could be seriously injured or even killed if you use this unit

where you don’t have adequate footing or traction can cause you to lose control or slip and fall.

You should not operate on inclines with a slope greater than 10 degrees, which is a 3.5 ft (1,5 m) rise over 20.0 ft (6,0 m). Always mow across slopes, never up and down.

Also note that the surface you are mowing can greatly impact control. Wet grass or leaves can seriously affect your footing and traction on a slope.

If you feel unsure about operating the unit on an incline, don’t do it. It’s not worth the risk.

Operator Safety

Moving Parts

This equipment has moving parts that can injure you or someone else. However, if you stand behind the handle properly and follow all the rules in this book, the unit is safe to operate.

The mower deck has a spinning mower blade that can amputate hands and feet. Do not allow anyone near the equipment while it is running!

To help you, the operator, use this equipment safely, it is equipped with an operator present safety system. Do NOT attempt to alter or bypass the system. See your dealer immediately if the system does not pass all the safety interlock system tests found in this manual.

Thrown Objects

Do n t perate this unit w h ut he entire grass catcher or discharge

guard (de lect r) in place.

NotAlso, do not allow anyone in the area while the unit is running! If

s meone does enter the area, shut the unit off immediately until they leave.

Debris Accumulation

Accumulation of grass and debris can result in a fire. Be sure to clean any accumulation of grass and debris with a brush or com ssed air, before and after operation.

Fuel and Maintenance

Gasoline is extremely flammable. Its vapors are also extremely flammable and can travel to distant ignition sources. Gasoline must only be used as a fuel, not as a solvent or cleaner. It should never be stored any place where its vapors can build up or travel to an ignition source like a pilot light. Fuel belongs in an approved, plastic, sealed gas can, or in the tractor fuel tank with the cap securely closed. Spilled fuel needs to be cleaned up immediately.

Proper maintenance is critical to the safety and performance of your unit. Be sure to perform the maintenance procedures listed in this manual, especially periodically testing the safety system.

1. Slopes are a major factor related to slip and fall accidents, which can result in severe injury. All slopes require extra caution. If you feel uneasy on a slope, DO NOT mow it.

2. Mow across slopes, never up-and-down. Exercise extreme CAUTION when changing directions on slopes. DO NOT mow steep slopes or other areas where stability or traction is in doubt. Refer to the Slope Guide at the back of this manual.

3. Use extra care with grass catchers or other attachments; these affect the handling and the stability of the machine.
