Operation 1. Park the machine on a level surface. 2. Unlock the engine cover latches and open the engine cover. Note: Determine the left and right sides of the machine from the normal operating position. 3. Remove the dipstick, wipe it clean, install the dipstick into the tube, and pull it out again. CAUTION The oil level should be in the safe range (Figure 9). 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.
Checking the Cooling System Filling the Fuel Tank Service Interval: Before each use or daily 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 180 days to ensure fuel freshness. Check level of coolant at the beginning of each day. Capacity of system is 13 qt. (12.3 l). 1. Carefully remove the radiator cap. Fuel tank capacity: 22 gallons (83 l).
DANGER 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. In certain conditions during fueling, static electricity can be released causing a spark which 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.
Industry Specifications: Vickers I-286-S (Quality Level), Vickers M-2950-S (Quality Level), Denison HF-0 4. If the level is low, add the appropriate fluid to raise the level to the upper mark. 5. Install the dipstick and cap onto the filler neck. Note: Many hydraulic fluids are almost colorless, making it difficult to spot leaks. A red dye additive for the hydraulic system oil is available in 2/3 oz. (20 ml) bottles. One bottle is sufficient for 4-6 gal (15-22 1) of hydraulic oil. Order part no.
1. Drive the machine slowly to a large, relatively open area. Lower the cutting unit, stop the engine, and apply the parking brake. CAUTION Shut the engine off and wait for all moving parts to stop before checking for oil leaks, loose parts, and other malfunctions. 2. Sit on the seat and depress the traction pedal. Try to start the engine. The engine should not crank. If the engine cranks, there is a malfunction in the interlock system that should be corrected before beginning operation.
Another characteristic to consider is the operation of the pedals that are connected to the brakes. The brakes can be used to assist in turning the machine. However, use them carefully, especially on soft or wet grass because the turf may be torn accidentally. Another benefit of the brakes is to maintain traction. For example, in some slope conditions, the uphill wheel slips and loses traction.
drive wheels to improve traction. The counterbalance pressure has been factory set to an optimal balance of aftercut appearance and traction capability in most turf conditions. Decreasing the counterbalance setting can produce a more stable cutting deck, but can decrease the traction capability. Increasing the counterbalance setting can increase the traction capability, but may result in aftercut appearance issues.
