SAFETY INSTRUCTIONS Improper use or maintenance of the machine can result in injury. To reduce the potential for injury, comply with the following safety instructions. 10. Do not run the engine in a confined area without adequate ventilation. Exhaust fumes are hazardous and could possibly be deadly. BEFORE OPERATING 11. Using the machine demands attention, and to prevent loss of control: 1. Read and understand the contents of this Operator's Manual before operating the machine.
SAFETY INSTRUCTIONS 22. Keep body and hands away from pin hole leaks or nozzles that eject hydraulic fluid under high pressure. Use paper or cardboard, not hands, to search for leaks. Hydraulic fluid escaping under pressure can have sufficient force to penetrate skin and do serious damage. If fluid is ejected into the skin it must be surgically removed within a few hours by a doctor familiar with this form of injury or gangrene may result. 23. Do not overspeed the engine by changing governor settings.

BEFORE OPERATING ACTIVATE AND CHARGE BATTERY 5. Remove filler caps. Slowly add electrolyte to each cell until level is up to fill ring. Install filler caps. 1. Since battery is not filled with electrolyte or activated, bulk electrolyte with 1.260 specific gravity must be purchased from a local battery supply outlet. IMPORTANT: Do not over fill battery. Electrolyte will overflow onto other parts of the machine and severe corrosion and deterioration will result. 6.
BEFORE OPERATING DANGER 30* 5W30, 10W–30 SYNTHETIC 5W20, 5W–30 °F–20 0 °C –30 –20 20 –10 32 40 0 60 10 80 20 100 30 40 * SAE 30 oil, if used below 40 F (4 C) will result in hard starting and possible engine bore damage due to inadequate lubrication. IMPORTANT: Check level of oil every 8 operating hours or daily.
BEFORE OPERATING CHECK HYDRAULIC SYSTEM FLUID The hydraulic system is designed to operate on SAE 10 W-30 engine oil or, as a substitute, SAE 10 W-40 engine oil. The machine's reservoir is filled at the factory with approximately 2.7 pints of SAE 10 W-30 engine oil. However, check level of hydraulic fluid before engine is first started and daily thereafter. 4. Run engine for approximately 1 minute, recheck level of fluid and add oil as required. 1 1.
CONTROLS Choke (Fig. 8) To start a cold engine, close carburetor choke by pulling choke control outward to the ON position. After engine starts, regulate choke to keep engine running smoothly. As soon as possible, open the choke by pushing it inward to the OFF position. A warm engine requires little or no choking.

The bearings and bushings that must be Iubricated are: front wheels (Fig. 21), rear wheel spindles (Fig. 22), front handle shaft (Fig. 23), traction roller latch pin (Fig. 25) and reverse speed control lever (Fig. 26) coring head switch (Fig. 27). Lubricate roller chain (Fig. 24) daily with SAE 30 oil.
Adjust axle height using height gauge. (Regulate Tire Pressure); refer to Check Frame Height. Check wheel assemblies for loose bearings or tire runout Replace bearings or tires Depth adjustment bolts set equally OK Check freeplay in tine arm and crank bearings. Replace bearings OK Coring to be done in L" (low) gear Adjust depth bolts; refer to Adjust Coring Depth. OK Check gear selection OK Loose coring head pivot points.
MAINTENANCE CAUTION 1. Place a drain pan below drain plug on axle. Clean area around drain plug (Fig. 29). Before servicing or making adjustments to the machine, stop engine and remove key from the switch. 2 ENGINE CARE The Engine Manual supplied with your Greens Aerator provides the maintenance procedures for service of the air cleaner, oil requirements, ignition components, etc.
MAINTENANCE 3. If coring head drive belt (Fig. 33) does not properly engage or disengage when entering or exiting the ground, check belt adjustment. Coring head mechanism should begin rotating 1" before tines contact turf. 1 2 1 Figure 33 Figure 31 1. Coring head drive belt 2. Adjusting screw 1. Control cover A. Remove control cover to expose adjusting screws (Fig. 31). B. To adjust tension, loosen (2) capscrews securing pump support bracket to chassis (Fig. 30). C. Loosen jam nuts on adjusting screw.
MAINTENANCE ADJUSTING SERVICE BRAKE If brake lever (Fig. 35) contacts control handle when brake is applied, an adjustment to the brake cable is required.
