GENERAL OPERATION
Operating On Slopes
Maintain sufficient fuel in the tank to ensure continu - ous operation. Cease operation if the power unit stability is question- able, or if the operator is uncomfortable or unsure of continuing safely. Attachments can affect the stability of the power unit. Each attachment will affect the power unit differently. Increase the amount of weight being transferred to the power unit from the attachment while operating on slopes. Refer to the Weight Transfer section. Always operate carefully and in a manner that does not compromise safety. Always keep the roll bar in the upright, locked posi- tion and fasten yourself securely with the seat belt. Refer to the following illustrations for power unit ca- pability with different equipment options.
WARNING Operation on slopes decreases the power unit sta- bility and increases the potential for unexpected dif- ficulties. Only experienced operators should operate the power unit on slopes and extra caution should be exercised. Use low range when operating on slopes greater than 15 degrees. Never shift between high and low range while on a slope. Always move the machine to level ground and engage the parking brake before shifting range. Avoid uneven, loose, or wet terrain. Stay clear of drop-offs, holes, ditches, rocks, or ob - jects that could cause a sudden and/or unexpected force on the power unit. Make slow and cautious starts, stops, and turns. Do not exceed the maximum degree of operation. Refer to the power unit capability illustrations. Turn downhill when possible and/or reduce the degree of turns. 20º Ensure a sufficient supply of fuel for continuous operation. A minimum of one-half tank of fuel is recommended. To prevent fuel spillage, do not remove the fuel tank cap while the power unit is on a slope. Failure to follow safety instructions while operating on slopes can result in injury or death. Always use caution when operating on slopes. ATTENTION Maximum angle of operation for the engine (Kubota WG972-GL) in the 4520Z power unit: 20° continuous, 30° intermittent^. ^Intermittent: the engine may operate between 20° and 30° for up to 10 minutes. If 10 minutes is reached, the engine must be returned to 20° or less to ensure proper oil lubrication. After returning to 20° or less, the intermittent cycle may be repeated.
