<- Go to Section TOC

Section 10 page 3

tm1727-TECHNICAL MANUAL

Section 10 - GENERAL

Group 05: Safety

First Aid Kit Be prepared if a fire starts.

Keep a first aid kit and fire extinguisher handy.

Keep emergency numbers for doctors, ambulance service, hospital, and fire department near your telephone.

Handle Chemical Products Safely

Material Safety Data Sheet Direct exposure to hazardous chemicals can cause serious injury. Potentially hazardous chemicals used with John Deere equipment include such items as lubricants, coolants, paints, and adhesives.

A Material Safety Data Sheet (MSDS) provides specific details on chemical products: physical and health hazards, safety procedures, and emergency response techniques.

Check the MSDS before you start any job using a hazardous chemical. That way you will know exactly what the risks are and how to do the job safely. Then follow procedures and recommended equipment.

(See your John Deere dealer for MSDS’s on chemical products used with John Deere equipment.)

Avoid High-Pressure Fluids

<- Go to Section TOC

Section 10 page 4

tm1727-TECHNICAL MANUAL

Section 10 - GENERAL

Group 05: Safety

High-Pressure Fluids Escaping fluid under pressure can penetrate the skin causing serious injury.

Avoid the hazard by relieving pressure before disconnecting hydraulic or other lines. Tighten all connections before applying pressure.

Search for leaks with a piece of cardboard. Protect hands and body from high pressure fluids.

If an accident occurs, see a doctor immediately. Any fluid injected into the skin must be surgically removed within a few hours or gangrene may result. Doctors unfamiliar with this type of injury should reference a knowledgeable medical source. Such information is available from Deere & Company Medical Department in Moline, Illinois, U.S.A.

Stay Clear of Rotating Drivelines

Rotating Drivelines Entanglement in rotating driveline can cause serious injury or death.

Keep tractor master shield and driveline shields in place at all times. Make sure rotating shields turn freely.

Wear close fitting clothing. Stop the engine and be sure PTO driveline is stopped before making adjustments, connections, or cleaning out PTO driven equipment.

Avoid Injury From Thrown Objects

<- Go to Section TOC

Section 10 page 5

tm1727-TECHNICAL MANUAL

Section 10 - GENERAL

Group 05: Safety

Safety Art-Objects Thrown at Person Extreme care must be exercised to avoid injury from thrown objects. Do not, under any circumstances, operate the mowerconditioner when other people are in the vicinity. Stones and other objects can be thrown great distances by the rotating cutting blades.

The cutterbar curtain is very important to reduce the potential for thrown objects. Always keep the curtain down when operating the mower-conditioner. Replace the curtain if it becomes worn or damaged.

For additional operator protection from thrown objects, it is required that this mower-conditioner be used with a tractor equipped with a complete operator enclosure.

Use Safety Lights and Devices

Prevent Collisions Prevent collisions between other road users, slow moving tractors with attachments or towed equipment, and self-propelled machines on public roads. Frequently check for traffic from the rear, especially in turns, and use hand signals or turn signal lights.

Use headlights, flashing warning lights, and turn signals day and night. Follow local regulations for equipment lighting and marking. Keep lighting and marking visible and in good working order. Replace or repair lighting and marking that has been damaged or lost.

Use a Safety Chain

<- Go to Section TOC

Section 10 page 6

tm1727-TECHNICAL MANUAL

Section 10 - GENERAL

Group 05: Safety

Safety Chain A safety chain will help control drawn equipment should it accidentally separate from the drawbar.

Using the appropriate adapter parts, attach the chain to the tractor drawbar support or other specified anchor location. Provide only enough slack in the chain to permit turning.

See your John Deere dealer for a chain with a strength rating equal to or greater than the gross weight of the towed machine.

Do not use safety chain for towing.

Tow Loads Safely

Tow Loads Stopping distance increases with speed and weight of towed loads, and on slopes. Towed loads with or without brakes that are too heavy for the tractor or are towed too fast can cause loss of control. Consider the total weight of the equipment and its load.

Observe these recommended maximum road speeds, or local speed limits which may be lower: If towed equipment does not have brakes, do not travel more than 32 km/h (20 mph) and do not tow loads more than 1.5 times the tractor weight.

If towed equipment has brakes, do not travel more than 40 km/h (25 mph) and do not tow loads more than 4.5 times the tractor weight.

Ensure the load does not exceed the recommended weight ratio. Add ballast to recommended maximum for tractor, lighten the load, or get a heavier towing unit. The tractor must be heavy and powerful enough with adequate braking power for the towed load. Use additional caution when towing loads under adverse surface conditions, when turning, and on inclines.

Support Machine Properly

<- Go to Section TOC

Section 10 page 7

tm1727-TECHNICAL MANUAL

Section 10 - GENERAL

Group 05: Safety

Support Properly Always lower the attachment or implement to the ground before you work on the machine. If you must work on a lifted machine or attachment, securely support the machine or attachment. If left in a raised position, hydraulically supported devices can settle or leak down.

Do not support the machine on cinder blocks, hollow tiles, or props that may crumble under continuous load. Do not work under a machine that is supported solely by a jack. Follow recommended procedures in this manual.

When implements or attachments are used with a tractor, always follow safety precautions listed in the implement operator′s manual.

"Lubricated" means coated with a lubricant such as engine oil, or fasteners with phosphate and oil coatings.

b

"Dry" means plain or zinc plated without any lubrication.

Metric Bolt and Cap Screw Torque Values, 2 of 2 DO NOT use these values if a different torque value or tightening procedure is given for a specific application. Torque values listed are for general use only. Check tightness of fasteners periodically.

Make sure fastener threads are clean and that you properly start thread engagement. This will prevent them from failing when tightening.

Shear bolts are designed to fail under predetermined loads. Always replace shear bolts with identical property class.

Tighten plastic insert or crimped steel-type lock nuts to approximately 50 percent of the dry torque shown in the chart, applied to the nut, not to the bolt head. Tighten toothed or serrated-type lock nuts to the full torque value.

Fasteners should be replaced with the same or higher property class. If higher property class fasteners are used, these should only be tightened to the strength of the original.
