CAUTION: Used without the safety alert symbol, CAUTION indicates a potentially hazardous situation which, if not avoided, may result in property damage. 1.1 Laws Pertaining to Spark Arresters Notice: State Health Safety Codes and Public Resources Codes specify that in certain locations spark arresters be used on internal combustion engines that use hydrocarbon fuels. A spark arrester is a device designed to prevent accidental discharge of sparks or flames from the engine exhaust.
1.2.11 ALWAYS store equipment properly when it is not being used. Equipment should be stored in a clean, dry location out of the reach of children. 1.2.12 ALWAYS operate machine with all safety devices and guards in place and in working order. DO NOT modify or remove safety devices. DO NOT operate machine if any safety devices or guards are missing or inoperative. 1.2.13 ALWAYS read, understand, and follow procedures in Operator's Manual before attempting to operate equipment. 1.
1.4.3 DO NOT test for spark on gasoline-powered engines, if engine is flooded or the smell of gasoline is present. A stray spark could ignite fumes. 1.4.4 DO NOT use gasoline or other types of fuels or flammable solvents to clean parts, especially in enclosed areas. Fumes from fuels and solvents can become explosive. 1.4.5 ALWAYS keep area around muffler free of debris such as leaves, paper, cartons, etc. A hot muffler could ignite them, starting a fire. 1.4.

Operation 3.
3.2.2 Check: -Oil level in engine -Fuel level -Condition of air cleaner -Tightness of external fasteners -Condition of fuel lines 3.3 TO Start (Fig.1) 3.3.1 Open fuel valve by moving lever to the right (a1). Note: If engine is cold, move choke lever to close position (b1). If engine is hot, set choke to open position (b2). 3.3.2 Turn engine switch to "ON" (e1). 3.3.3 Open throttle by moving it slightly to left (d1). 3.3.4 Pull starter rope (c).
3.4 To Stop 3.4.1 Reduce engine RPM to idle by moving throttle completely to right (d2). 3.4.2 Turn engine switch to "OFF". 3.4.3 Close fuel valve by moving lever to the left (a2). 3.5 Application This plate is designed for compacting loose, granular soils, gravel, and paving stones. It is intended to be used in confined areas and areas next to structures such as walls, curbs, and foundations. Plates equipped with water tanks can be used for compacting asphalt.
4. Maintenance 4.1 Periodic Maintenance The chart below lists basic engine maintenance. Refer to engine manufacturer's Operation Manual for additional information on engine maintenance. Daily before starting After first 20 hours Every Every Every 2 weeks or month or year or 50 hours 100 hours 300 hours Check fuel level. Check engine oil level. Inspect fuel lines. Inspect air filter. Replace as needed. Check and tighten external hardware. Check and adjust drive belt. Clean air cleaner elements.
4.3 Drive Belt (Fig.3) On new machines or after installing a new belt, check belt tension after first 20 hours of operation. Check and adjust belt every 50 hours thereafter. To change the belt: 4.3.1 Remove the beltguard and remove the four hex nuts (a) holding pulley halves (b) together. Remove outer pulley half and remove belt. 4.3.2 Install new belt on pulley and secure pulley halves together with hex nuts. Adjust tension on belt by adding or removing spacers (c) between pulley halves.
To change fluid: 4.4.1 Remove beltguard, belt, and hose from water tank. 4.4.2 Remove four screws (b) securing console assembly to baseplate and lift console assembly from baseplate. 4.4.3 Remove end cover (c) from bearing exciter assembly. Outer bearing race will remain with cover. 4.4.4 Tip baseplate up and drain fluid from exciter assembly. Dispose of used fluid in an appropriate manner. Contact local recycling center. 4.4.
a 4.5.1 Remove spark plug and inspect it. 4.5.2 Replace plug if the insulator is cracked or chipped. 4.5.3 Clean spark plug electrodes with a wire brush. 4.5.4 Set the electrode gap (a). 4.5.5 Tighten spark plug securely. CAUTION: A loose spark plug can become very hot and may cause engine damage. Fig. 5 4.6 Engine Oil (Fig. 6) 4.6.1 Drain oil while the engine is still warm. a 4.6.2 Remove the oil fill plug (a) and drain plug (b) to drain oil. 4.6.3 Install drain plug. 4.6.
4.7 Air Cleaner (Fig. 7) WARNING NEVER use gasoline or other types of low flash point solvents for cleaning the air cleaner. A fire or explosion could result. NEVER run engine without air cleaner: Severe engine damage will occur. CAUTION The engine is equipped with a dual element air cleaner. Under normal operating conditions, elements should be cleaned once every week. Under severe, dry and dusty conditions, the elements should be maintained daily.
b a Fig. 8 4.9 Carburetor Adjustment (Fig. 9) 4.9.1 Start the engine and allow it to warm up to operating temperature. 4.9.2 Set the pilot screw (a) 2 turns out. See Note. 4.9.3 With the engine idling, turn the pilot screw (a) in or out to the setting that produces the highest rpm. 4.9.4 After the pilot screw is adjusted, turn the throttle stop screw (b) to obtain the standard idle speed. See Technical Data.
4.10 Troubleshooting Problem / Symptom Reason / Remedy • Engine throttle control is not completely open. • Throttle control is not adjusted correctly. • Ground is too wet, plate sticking. Allow soil to dry before compacting. -Plate does not develop • Drive belt is loose or worn, slipping on pulleys. Adjust or full speed. replace belt. Check that the engine mounting bolts are tight. -Poor compaction. • Exciter bearings binding. Check condition and level of oil in exciter. Add or change oil.
4.12 Lifting Machine See Technical Data for the weight of the machine. To lift machine manually: 4.12.1 Stop the engine. 4.12.2 Obtain help from a partner and plan the lift. 4.12.3 Grasp the machine by its cage and lifting slot. 4.12.4 Lift the machine.
