Safe Operating Practices
Training
•Read the tractor and Ultra Vac QDS Operator’s Manuals and other training material. If the operator(s) or mechanic(s) can not read English it is the owner’s responsibility to explain this material to them.
•Become familiar with the safe operation of the equipment, operator controls, and safety signs.
•All operators and mechanics should be trained. The owner is responsible for training the users.
•Never let children or untrained people operate or service the equipment. Local regulations may restrict the age of the operator.
•The owner/user can prevent and is responsible for accidents or injuries occurring to himself or herself, other people or property.
Preparation
•Evaluate the terrain to determine what accessories and attachments are needed to properly and safely perform the job. Only use on machines approved by Exmark.
•Wear appropriate clothing including safety glasses, substantial footwear, long trousers, and hearing protection. Do Not operate when barefoot or when wearing open sandals.
CAUTION
This machine produces sound levels in excess of 85 dBA at the operator’s ear and can cause hearing loss through extended periods of exposure.
Wear hearing protection when operating this machine.
•Inspect the area where the equipment is to be used and remove all rocks, toys, sticks, wires, bones, and other foreign objects which can be thrown by the machine and may cause personal injury to the operator or bystanders.
Operation
•Operate only in daylight or good artificial light, keeping away from holes and hidden hazards.
•Never mow with the discharge deflector raised, removed or altered unless there is a grass collection system or mulch kit in place and working properly.

Safety
DANGER
There are rotating blades in the blower and under the mower deck. Blade contact can cause serious operator or bystander injury or even death.
•Do Not reach into blower unless rotation indicator has stopped. Disengage PTO, stop engine, remove key, wait for all moving parts to stop. Engage parking brake.
•Never operate mower unless discharge deflector, entire grass collection system, or mulch kit is installed.
•Stop engine, wait for all moving parts to stop, remove key and engage parking brake:
–Before checking, cleaning or working on the mower.
–After striking a foreign object or abnormal vibration occurs (inspect the mower for damage and make repairs before restarting and operating the mower).
–Before clearing blockages.
–Whenever you leave the mower.
WARNING
Hands, feet, hair, clothing, or accessories can become entangled in rotating parts. Contact with the rotating parts can cause traumatic amputation or severe lacerations.
•Do Not operate the machine without guards, shields, and safety devices in place and working properly.
•Keep hands, feet, hair, jewelry, or clothing away from rotating parts.
•Stop the blades, slow down, and use caution when crossing surfaces other than grass and when transporting the mower to and from the area to be mowed.
•Be aware of the mower discharge path and direct discharge away from others.
Slope Operation
Use Extreme caution when mowing and/or turning on slopes as loss of traction and/or tip-over could occur. The operator is responsible for safe operation on slopes.
DANGER
Operating on wet grass or steep slopes can cause sliding and loss of control. Wheels dropping over edges, ditches, steep banks, or water can cause rollovers, which may result in serious injury, death or drowning.
•Do Not mow slopes when grass is wet.
•Do Not mow near drop-offs or near water.
•Do Not mow slopes greater than 15 degrees.
•Reduce speed and use extreme caution on slopes.
•Avoid sudden turns or rapid speed changes.
•Keep the roll bar in the raised and locked position and use seat belt.
•See inside the back cover to determine the approximate slope angle of the area to be mowed.
•Use a walk behind mower and/or a hand trimmer near drop-offs, ditches, steep banks or water. (Figure 3).

Safety
Figure 3
1.Safe Zone-Use the mower here on slopes less than 15 degrees
2.Danger Zone-Use a walk behind mower and/or hand trimmer on slopes greater than 15 degrees, near drop-offs and water.
3.Water
•Remove or mark obstacles such as rocks, tree limbs, etc. from the mowing area. Tall grass can hide obstacles.
•Watch for ditches, holes, rocks, dips and rises that change the operating angle, as rough terrain could overturn the machine.
•Avoid sudden starts when mowing uphill because the mower may tip backwards.
•Be aware that operating on wet grass, across steep slopes or downhill may cause the mower to lose traction. Loss of traction to the drive wheels may result in sliding and a loss of braking and steering.
•Always avoid sudden starting or stopping on a slope. If tires lose traction, disengage the blades and proceed slowly off the slope.
•Follow the manufacturer’s recommendations for counter weights to improve stability. Always install and remove the Ultra Vac QDS, including counter weights, as instructed. Failure to do so will cause a reduction in stability or traction. Do Not operate the mower with only a portion of the Ultra Vac QDS installed.
•Use extreme care with grass catchers or attachments. These can change the stability of the machine and cause loss of control. The stability and traction of the machine will change as the Ultra Vac QDS hopper fills with grass clippings.
Use progressively greater care on slopes as the hopper fills.
Maintenance and Storage
•Disengage drives, set parking brake, stop engine and remove key or disconnect spark plug wire. Wait for all movement to stop before adjusting, cleaning or repairing.
•Use care when checking blades. Wrap the blade(s) or wear gloves, and use caution when servicing them. Only replace damaged blades. Never straighten or weld them.
•Keep all guards, shields and all safety devices in place and in safe working condition.
•Check all bolts frequently to maintain proper tightness.
•Frequently check for worn or deteriorating components that could create a hazard.
•All replacement parts must be the same as or equivalent to the parts supplied as original equipment.
