CAUTION: Used without the safety alert symbol, CAUTION indicates a potentially hazard- ous 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.
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 work- ing order.
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.
3. Operation 3.1 Recommended Fuel The engine requires regular grade unleaded gasoline, 87 octane or higher. Use only fresh, clean gasoline. Gasoline containing water or dirt will damage fuel system. Consult engine owner's manual for complete fuel specifications. 3.2 Before Starting 3.2.1 Read and understand safety and operating instructions at beginning of this manual.
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 le (d1).
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 le (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.
4. Maintenance 4.1 Periodic Maintenance The chart below lists basic engine maintenance. Refer to engine manufacturer's Opera- tion Manual for additional information on engine maintenance. A er Every 2 Every Every Daily before first 20 weeks or month or year or starting hours 50 hours...
4.3 Drive Belt (Fig.3) On new machines or a er installing a new belt, check belt tension a er first 20 hours of operation. Check and adjust belt every 50 hours therea er. To change the belt: 4.3.1 Remove the beltguard and remove the four hex nuts (a) holding pulley halves (b) together.
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 li console assembly from baseplate. 4.4.3 Remove end cover (c) from bear- ing exciter assembly. Outer bearing race will remain with cover.
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.
4.7 Air Cleaner (Fig. 7) NEVER use gasoline or other types of low flash point solvents for cleaning the air cleaner. A fire or explosion could result. WARNING NEVER run engine without air cleaner: Severe engine damage will occur. CAUTION The engine is equipped with a dual element air clean- er.
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 produc- es the highest rpm.
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 reach •...
4.12 Li ing Machine See Technical Data for the weight of the machine. To li machine manually: 4.12.1 Stop the engine. 4.12.2 Obtain help from a partner and plan the li . 4.12.3 Grasp the machine by its cage and li ing slot. 4.12.4 Li the machine.
5. Compaction Tips 5.1 Soil Drop Test: Soil preparedness refers to the “wetness” of the dirt or soil. Soil needs to be 50% dry and 50% wet, before starting compaction. A simple “hand test” can determine this. Pick up a handful of soil with your hand and squeeze the dirt. Observe whether the soil is powdery or if it breaks apart when dropped.
5.3 Compaction Terms 5.3.1 Cohesive soils: Clays and mixes have a particular particle size of less than .003” or .002” and are typically classified as cohesive soils. This type of soil is primarily used for retaining pond beds and mound fills. These soils are dense due to the strongly bound molecular attraction.

5.3.4 Static force: Found in the deadweight of machines, static force applies pressure downward on soil surfaces. As a result, soil particles compress in the topsoil layer. 5.3.5 Vibratory force: This force is engine-driven, creating a downward force, in addition to the machine's static weight.
