OPERATING INSTRUCTIONS NOTE ELECTRICAL EQUIPMENT OFF ACCESSORIES ON WARNING LIGHTS & INSTRUMENTS ON THERMOSTAT HEATER ON STARTING MOTOR ON A safety starter permits the starting motor to operate only when the transmission high-low shift lever is in neutral. CAUTION Always shift both levers to neutral before starting the engine. Never attempt to start the engine while standing beside the tractor - Always sit in the seat.
OPERATING INSTRUCTIONS STARTING PROCEDURE GASOLINE/LP ENGINE (cont.) Cold Weather Starting (L/P Engines): 1. Depress the clutch pedal and move the shift levers to the neutral position. 2. Apply the parking brake. 3. Place the hydraulic control lever(s) in the neutral position. 4. Place the P.T.O. control lever in the disengaged position. 5. Open the hand throttle slightly and do not press the foot pedal. 6. Turn the key to its start position; when engine starts, release the key. 7.
OPERATING INSTRUCTIONS COOLANT IMMERSION HEATER (Accessory): The coolant immersion heater consists of a heating element installed in the right side of the engine block. A detachable cord is provided for plugging into an electrical outlet. The heater provides for easier starting by warming the engine coolant and oil and is effective to -20ºF. To operate the Heater: 1. Plug in the heater to a suitable 115-Volt outlet and leave for two hours before carrying out the cold weather starting procedures. 2.
OPERATING INSTRUCTIONS TO OPERATE THE TRANSMISSION Follow these steps to operate the transmission. When the high-low shift lever is in the low range, 1st, 2nd, 3rd, 4th, and (R1) gear ratios can be selected with the gearshift lever. When the high-low lever is in the high range, 5th, 6th, 7th, 8th, and (R2) gear ratios can be selected. IMPORTANT Avoid using the clutch pedal as a “footrest” (riding the clutch). Prolonged operation in this manner will cause premature failure of the clutch components.
OPERATING INSTRUCTIONS TO OPERATE THE SCUBBING EQUIPMENT (cont.) Follow these steps to operate the scrubbing equipment. 1. Engage the solution flow Standard Machine: Lift the solution control lever located near the operator’s left foot (see Figure 4). Camel Machine: Turn on the “Recycling System” switch and dial in the desired detergent flow (see Figure 8). 2. Engage brush rotation by moving the inboard lever on the brush control valve (see Figure 4).
OPERATING INSTRUCTIONS POST-OPERATION INSTRUCTIONS - ENGINE STOPPED Perform these steps after the machine has been shut down. -Close the LPG fuel valve as required. -Check for string or wire tangled on scrub brushes. -Check scrub brushes for wear or damage. -Check squeegees for wear, damage, or adjustment. -Drain and clean recovery tanks. -Clean the recovery tank’s screen and float. -Check vacuum pipes and hoses for obstructions. -Check the slash skirt for wear, damage, or adjustment.
OPERATING INSTRUCTIONS TO OPERATE VACUUM WAND (cont.) 2. Remove wand and hose assembly from mounting clips on top of the tanks. 3. Push hose end unto 1.50" fitting located on the left hand squeegee assembly. 4. Position the LH squeegee valve to connect the pick up hose to the vacuum wand hose by moving flat lever to the left to stop position. 5. Position the right hand squeegee valve lever to the left to close off the right hand pickup hose. 6. Start the engine. 7. Place throttle in the “full” rpm position.

HELPFUL HINTS FOR CLEANING OPERATION SIDE AISLES MAIN AISLE P4134/0001 P4134 SIDE AISLES FIGURE 12 WARNING Do not turn the steering wheel sharply when the machine is in motion. The scrubber is very responsive to movement of the steering wheel. Do not make sudden turns. HELPFUL HINTS FOR CLEANING OPERATION Follow these hints to get the best possible cleaning results: -Scrub in straight paths, Do not bump posts. Do not scrape the sides of the machine -Plan scrubbing in advance.
SERVICE INSTRUCTIONS COUNTERBALANCE SPRINGS TRACTOR FOOT REST P4236 P4236 FIGURE 16 EVERY 1200 HOURS or EVERY TWO YEARS 37. Drain and flush radiator coolant system BRUSH LOAD AND BRUSH WEAR Factors affecting brush wear are type of bristle, bristle, area, and load on the bristles. See your authorized distributor for the type of brush and bristle most suitable. Brush load may be adjusted by adding or removing counterbalance springs (see Figure 16).
SERVICE INSTRUCTIONS CASTER WHEEL LOCKING PLATE P4237 P4237 FIGURE 17 SQUEEGEE TOOL LEVEL ADJUSTMENT Individual level adjustment at each squeegee is possible to bring flared squeegee ends to proper floor contact. Loosening one locked adjustment screw and tightening the other causes the entire tool assembly to tip on the pivot pin until the squeegee rubber is perpendicular (level) to the floor. Tighten the locking nuts after adjusting the screw.
SERVICE INSTRUCTIONS ADJUSTING BLOCKS LIFT LINK P4240 P4240 FIGURE 19 SQUEEGEE LIFT HEIGHT ADJUSTMENT The height of the squeegee tools in the full up position is adjusted so that the right side squeegee tool assembly clears the stop bracket by .25" to .50" (see Figure 19). To change the adjustment: 1. Place squeegee control lever in the full down position. 2. Loosen (2) two adjusting blocks (see Figure 19) clamped to squeegee lift arms.

SERVICE INSTRUCTIONS P4245b1 FIGURE 27 P4245b2 FIGURE 28 CHECKING THE ENGINE COOLING SYSTEM Under some operating conditions there is a tendency for the coolant to boil and be expelled out of the radiator expansion chamber overflow tube (see Figure 27). Normally, this loss of coolant would be of little consequence, but repeated occurrences can lead to considerable loss of coolant and would be necessitate topping off the radiator.
SERVICE INSTRUCTIONS P4245c1 FIGURE 29 P4245c2 FIGURE 30 CHECKING THE FUEL FILTER/SEDIMENT SEPARATOR (cont.) After draining the filter/separator, bleed the fuel injection system as outlined below. WARNING Do not use fuels or solvents in a confined area. Work in a well ventilated area. To change the fuel filter: 1. Close the fuel tank shut off by turning in a clockwise direction. 2. Unscrew the central retaining bolts (see Figure 29, Item 1) 3. Remove the glass bowl (see Figure 29, Item 4) 4.
SERVICE INSTRUCTIONS P4245d1 FIGURE 31 P4245d2 FIGURE 32 SERVICEING THE AIR CLEANER The air cleaner consists of an inner and an outer paper element and is located under the radiator cowling.

Pry the alternator away from the engine and tighten the mounting bolts. 3.
SERVICE INSTRUCTIONS To service the battery: Check the electrolyte level in the battery every 50 hours. CAUTION When the alternator is charging, an explosive gas is produced inside the battery. Always check the electrolyte level with the engine stopped. DO not use an exposed flame and do not smoke when checking the battery. To check the battery electrolyte level: 1. Clean the top of the battery and remove the vent plugs. 2. Check the electrolyte level.
SERVICE INSTRUCTIONS P4245j1 FIGURE 43 P4245j2 FIGURE 44 BRAKE ADJUSTMENT If the brake pedal travel becomes excessive, or if the travel of one pedal is not equal to the other, adjust in the following manner: 1. Disconnect the brake return spring on the right pedal allowing the pedal to drop. 2. Push the pedal down to take up any slack in the linkage. 3.
SERVICE INSTRUCTIONS To change the spark plugs: To maintain peak engine efficiency and performance, clean the spark plugs every 300 hours and install new plugs every 600 hours. To remove the spark plugs: 1. Gain access to the spark plugs by loosening the battery tray wing nut and swinging the battery out. 2. Remove the distributor-to-spark plug wire from the plugs. 3. Remove the high tension wires.
