Hustler Turf Z4 manual Hydraulic system, Fuel system

Hydraulic system

IMPORTANT: Never use hydraulic or automatic transmis- sion fluid in this system; use only motor oil as specified. Remember, dirt is the primary enemy of any hydraulic system.

WARNING: Hydraulic fluid escaping under pressure may have sufficient force to penetrate skin and cause serious injury. Foreign fluid injected into the skin must be surgically removed within a few hours by a doctor, familiar with this form of injury, or gangrene may result.

Before applying pressure to hydraulic system, make sure all connections are tight and all hoses and lines are in good condition. To find a leak under pressure, use a piece of cardboard or wood — never use your hands. Relieve all pressure in the system before dis- connecting or working on hydraulic lines. To relieve pressure, lower all attachments and shut off engine.

Check oil level in hydraulic system after every 50 hours of operation or weekly, whichever occurs first. Check more often if system appears to be leaking or otherwise malfunctioning.

Fluid level should be 1” (2.54cm) from top of reservoir. Use only SAE 20W50 SL/SM service motor oil. Figure 9-1

Change hydraulic system filter element after first 50 hours of tractor operation, then replace filter and oil in reservoir every 500 hours thereafter. Figure 9-1

The system filter is located in front of the hydraulic reservoir. A standard oil filter wrench is used to change filter, threads are right handed. Use a Hustler approved filter element only.

IMPORTANT: Prefill the filter element with clean oil, before installing, to prevent drawing air into the system pump.

Fuel system

DANGER: To avoid personal injury or property dam- age, use extreme care in handling gasoline. Gasoline is extremely flammable and the vapors are explosive.

DANGER: Observe usual fuel handling precautions: Do not smoke while refueling. Extinguish all ciga- rettes, cigars, pipes and other sources of ignition.

•Do not remove fuel cap or fill tank with engine running or while engine is hot. Clean up any fuel spills.

•Allow engine to cool before storing machine inside a building.

•Keep fuel away from open flame or spark and store machine away from open flame or spark or pilot light such as on a water heater or appliances.

•Use extreme care when handling gasoline and other fuels. They are extremely flammable and vapors are explosive. A fire or explosion from fuel can burn you and others and can damage property.

•Refuel outdoors. Never refuel or drain the fuel from the machine indoors.

•Never attempt to start engine when there is a strong odor of gasoline or diesel fuel fumes present. Locate and correct cause.

•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 fill fuel containers inside a vehicle or on a truck or trailer bed with interior carpets or plastic truck bed liners. Always place fuel containers on the ground away from your vehicle before filling.

•When practical, remove gas-powered 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 the truck or trailer using a portable container and not a fuel dispenser nozzle. If a gasoline dispenser nozzle must be used, keep the noz- zle in contact with the rim of the fuel tank or container opening at all times until fueling is complete. Do not use a nozzle lock-open device.

•Never use gasoline for cleaning parts.

•Read and observe safety precautions elsewhere in this manual.

WARNING: Gasoline is harmful or fatal if swal- lowed.

Long-term exposure to vapors can cause serious injury and illness.

Avoid prolonged breathing of vapors.

Keep face away from nozzle and gas tank or fuel con- tainer opening.

Keep gas away from eyes and skin.

If fuel is spilled on clothing, change clothing immedi- ately.

The fuel tanks are located in the tractor’s fenders.

Use regular unleaded gasoline with an octane rating of 87 or higher. IMPORTANT: Never use methanol, gasoline containing methanol, or gasohol containing more than 10% ethanol because the fuel system could be damaged. Do not mix oil with gasoline.

The fuel filter is an in-line filter located in the fuel line between the fuel tank and the fuel pump. Figure 9-2

A fuel shut-off valve is located on each tractor. The location and operation of the fuel valve will vary depending upon the unit. Close the fuel valve to prevent fuel flow to the engine. The valve’s two other positions will allow fuel to be drawn from either one or the other fuel tank. Figure 9-3
