General Information DANGER Because diesel fuel is flammable, use caution when storing or handling it. Do not smoke while filling the fuel tank. Do not fill fuel tank while en- gine is running, hot, or when machine is in an en- closed area.
Page 19: Fill Fuel Tank
Fill Fuel Tank The engine runs on No. 2 diesel fuel. Fuel tank capacity is approximately 6.0 gallons (22.7 L). 1. Clean area around fuel tank cap. 2. Remove fuel tank cap. 3. Fill tank to about one inch below the top of tank, (bot- tom of the filler neck).
Page 20: Drain Water From Fuel Filter/Water Separator
Drain Water from Fuel Filter/Water Separator Any water accumulation should be drained from the fuel filter/water separator before each use or when warning light glows. 1. Position machine on a level surface and stop the en- gine. Note: Because the accumulated water will be mixed with diesel fuel, drain the fuel filter into a suitable con- tainer and dispose of properly.

Adjustments Adjust Alternator Belt Make sure belt is properly tensioned to assure the prop- er operation of the machine and prevent unnecessary wear. On new belts, check tension after 8 hours of op- eration. The engine belt should be tensioned so it deflects 0.20 inch (5 mm) with a 2 to 3 lbf (9 to 13 N) load applied mid- way between the crankshaft and alternator pulley.

Page 67 Problem Possible Cause No traction exists in either direction. Parking brake is not released. Oil level in reservoir is low. Hydrostat by--pass valve is open. Charge pressure is low (see Charge Pressure Relief Valve (R4) Pressure Test). Traction pump (P3) or wheel motor(s) are worn or damaged (see Traction Drive Hydrostat (P3) Flow and Wheel Motor Efficiency Tests).
Page 68 Problem Possible Cause Cutting units will not lift or lift slowly. Engine speed is too low. Reservoir oil level is low. Lift cylinder linkage is binding or broken. Lift cylinder bushings bind. Charge circuit pressure is low (see Charge Relief Valve (R4) Pres- sure Test).
Page 69 Problem Possible Cause The steering wheel can be turned The steering cylinder is worn. without the rear wheel turning. The gear set in the steering control valve is worn. Steering response is too slow and Oil supply to the steering control valve is insufficient. heavy when trying to turn quickly.

Safety Relays Two styles of safety relays have been used on Green- smaster 3250−D machines. Later production machines (after serial number 250000000) have a different relay terminal arrangement than relays on earlier machines (Fig. 4). Relay operation is identical regardless of termi- nal layout.
Page 169: Seat Switch
Seat Switch The seat switch is normally open and closes when the operator is on the seat. If the neutral switch or traction interlock switch is open when the operator raises out of the seat, the engine will stop. The switch and its electri- cal connector are located directly under the seat.

Lower Reels Time Delay This is a solid state timer. Upon the application of power, the load is energized and the time delay is started. After 6 seconds the load is de−energized. 1. Connect voltmeter across test load and test load to timer.
Page 178: Diode Circuit Boards
Diode Circuit Boards Each circuit board contains four diodes. The diodes are used for circuit protection from inductive voltage spikes and for safety circuit logic. Diode D8 is not used. Diode D1 This diode prevents current flow to solenoid S3 when so- lenoids S2 and S4 are energized through lower relay R6.
Page 179: Solenoid Valve Coils
Solenoid Valve Coils Note: Prior to taking small resistance readings with a digital multimeter, short the test leads together. The me- ter will display a small resistance value (usually 0.5 ohms or less). This resistance is due to the internal re- sistance of the meter and test leads.

Battery Service The battery is the heart of the electrical system. With regular and proper service, battery life can be extended. Additionally, battery and electrical component failure can be prevented. CAUTION When working with batteries, use extreme cau- tion to avoid splashing or spilling electrolyte. Electrolyte can destroy clothing and burn skin or eyes.
