Slope Operation

Slopes are a major factor related to loss-of-control and tip-over accidents, which can result in severe injury or death. All slopes require extra caution.

  • Do not operate the traction unit on hillsides or slopes exceeding the angles recommended in Stability Data, and those in the attachment Operator's Manual. See also the .

  • Operate up and down slopes with the heavy end of the traction unit uphill. Weight distribution changes. An empty bucket will make the rear of the traction unit the heavy end, and a full bucket will make the front of the traction unit the heavy end. Most other attachments will make the front of traction unit the heavy end.

  • Raising the loader arms on a slope will affect the stability of the machine. Whenever possible, keep the loader arms in the lowered position when on slopes.

  • Remove or add attachments on level ground.

  • Remove obstacles such as rocks, tree limbs, etc. from the work area. Watch for holes, ruts, or bumps, as uneven terrain could overturn the traction unit. Tall grass can hide obstacles.

  • Use only Toro-approved attachments. Attachments can change the stability and the operating characteristics of the traction unit. Warranty may be voided if used with unapproved attachments.

  • Keep all movements on slopes slow and gradual. Do not make sudden changes in speed or direction.

  • Avoid starting or stopping on a slope. If the traction unit loses traction, proceed slowly, straight down the slope.

  • Avoid turning on slopes. If you must turn, turn slowly and keep the heavy end of the traction unit uphill.

  • Do not operate near drop-offs, ditches, or embankments. The traction unit could suddenly turn over if a track goes over the edge of a cliff or ditch, or if an edge caves in.

  • Use caution when operating on wet grass. Reduced traction could cause sliding.

  • Do not park the traction unit on a hillside or slope without lowering the attachment to the ground and setting the parking brake.

g009027

Adding Fuel

Use only clean, fresh diesel fuel or biodiesel fuels with low (<500 ppm) or ultra low (<15 ppm) sulfur content. The minimum cetane rating should be 40. Purchase fuel in quantities that can be used within 180days to ensure fuel freshness.

Fuel tank capacity: 41 L (11 US gallons)

Use summer-grade diesel fuel (No. 2-D) at temperatures above -7°C (20°F) and winter grade (No. 1-D or No. 1-D/2-D blend) below that temperature. Using winter-grade fuel at lower temperatures provides lower flash point and cold flow characteristics, which eases starting and reduces fuel filter plugging.

Using summer-grade fuel above -7°C (20°F) contributes toward longer fuel pump life and increased power compared to winter-grade fuel.

Important: Do not use kerosene or gasoline instead of diesel fuel. Failure to observe this caution will damage the engine.

Warning

Fuel is harmful or fatal if swallowed. Long-term exposure to vapors can cause serious injury and illness.

  • Avoid prolonged breathing of vapors.

  • Keep face away from nozzle and fuel tank or conditioner opening.

  • Keep fuel away from eyes and skin.

Biodiesel Ready

This machine can also use a biodiesel blended fuel of up to B20 (20% biodiesel, 80% petrodiesel). The petrodiesel portion should be low or ultra low sulfur. Observe the following precautions:

  • The biodiesel portion of the fuel must meet specification ASTM D6751 or EN14214.

  • The blended fuel composition should meet ASTM D975 or EN590.

  • Painted surfaces may be damaged by biodiesel blends.

  • Use B5 (biodiesel content of 5%) or lesser blends in cold weather.

  • Monitor seals, hoses, gaskets in contact with fuel as they may be degraded over time.

  • Fuel filter plugging may be expected for a time after converting to biodiesel blendsd.

  • Contact your distributor if you wish for more information on biodiesel.

Filling the Fuel Tanks

Danger

In certain conditions, fuel is extremely flammable and highly explosive. A fire or explosion from fuel can burn you and others and can damage property.

  • Fill the fuel tanks outdoors, in an open area, when the engine is cold. Wipe up any fuel that spills.

  • Never fill the fuel tanks inside an enclosed trailer.

  • Never smoke when handling fuel and stay away from an open flame or where fuel fumes may be ignited by a spark.

  • Store fuel in an approved container and keep it out of the reach of children. Never buy more than a 30-day supply of fuel.

  • Do not operate without entire exhaust system in place and in proper working condition.

Danger

In certain conditions during fueling, static electricity can be released, causing a spark that can ignite the fuel vapors. A fire or explosion from fuel can burn you and others and can damage property.

  • Always place fuel containers on the ground away from your vehicle before filling.

  • Do not fill fuel containers inside a vehicle or on a truck or trailer bed, because interior carpets or plastic truck bed liners may insulate the container and slow the loss of any static charge.

  • When practical, remove equipment from the truck or trailer and refuel the equipment with its wheels on the ground.

  • If this is not possible, then refuel such equipment on a truck or trailer from a portable container rather than from a fuel-dispenser nozzle.

  • If you must use a fuel-dispenser nozzle, keep the nozzle in contact with the rim of the fuel tank or container opening at all times until fueling is complete.

Fill the fuel tanks as shown in Figure 24.

Note: The fuel-tank caps click when you close them securely. Use the brackets to lock the fuel tanks.
