• Civil engineering jobs for the compaction of all types of soils, especially cohesive soils.

• Trenches for cables, water lines, gas pipelines, backfills and structural fills, etc.

• Stabilization of slopes, dams, dikes and levees.

• Road construction for the compaction of base course concrete, marginal strip and sub-surface compaction jobs.

• Road repairs of all types.

• Building construction for the compaction of concrete and sub-soils in cellars and shed floors.

• Garden construction and parks for the stabilization of roads and paths. Description of function The vibration required for compaction is produced by the ramming system, which is firmly attached to the ramming shoe. The engine, which is flanged to the crankcase and is held in place by four screws, drives the ramming system over a gear transmission and a connecting rod. The engine torque is transmitted by means of a centrifugal clutch. The centrifugal clutch interrupts the flow of power to the ramming system at low engine speeds, thus allowing for a perfect idling of the engine. The advance movement in forward direction of the rammer is ensured by means of the tilt of the ramming system. The engine can be switched off with the throttle control. The drive engine works according to the diesel principle, and is started mechanically by means of a recoil starter. The engine is air cooled and the air necessary for combustion is directed through a precleaner and a dry-type air filter. The guide handle and frame are mounted on the ramming system with a set of shockmounts, therefore assuring a minimum transmission of vibrations to the hands of the operator.

1.12 Recommendations on compaction

Soil conditions:The maximum compaction depth of the soil depends on several factors relating to the nature of the soil, such as watercontent, grain-size distribution, etc. It is therefore not possible to specify a given layer depth. Recommendation: In each case determine the maximum possible compaction depth through compaction tests and soil samples.

1. Always shut off the engine and close the fuel valve when transporting the rammer.2. Use lifting equipment with minimum lifting capacity of 220.5 lbs. (100 kg).

3. Use the central lifting point (a) when lifting the rammer.

4. WACKER recommends transporting rammers upright whenever possible; however, a rammer should not beallowed to fall over.If the rammer cannot be secured in the upright position, tie down the rammer to the transport vehicle to prevent it from tipping, falling, or rolling. Lay the rammer down only as shown below and tie it to the vehicle at points (b) and (c). CAUTION: Drain the fuel tank as required to prevent fuel leaking from the cap (d). CAUTION: After transporting the rammer horizontally, upright the rammer and allow the oil to drain back through the engine. It may take up to 45 minutes for the oil level to recover. Failure to do so may result in engine damage.Note: Refer to the specifications in the safety instructions. 1027SD77

1.14 Recommended Fuel

Use only pure diesel fuel. Close the fuel cap immediately. It is important to maintain cleanliness to avoid problems with the fuel injection system, and to prevent premature clogging of the fuel filter. To avoid contamination, DO NOT open the fuel line or the fuel pump or any other point of the fuel system, not even to bleed air. The fuel pump will bleed automatically. This applies even if the fuel tank was run dry. If this happens, refill the fuel tank.

1.15 Before Starting

1. Read safety instructions at the beginning of this

2. Perform daily maintenance items.

3. Place rammer on loose soil or gravel. DO NOT start

rammer on hard surfaces such as asphalt or concrete.

Keep vibratory rammer clean and dry. Avoid no-load strokes. Never allow the rammer to run full throttle when forcing away material or when lifting the equipment. CAUTION: To prevent damage to the rammer, do not allow the rammer to run on its side. If the rammer should tip on its side, place the rammer in the position shown below, then shut off the engine by moving the throttle control lever through the detent to the off position. Note: The rammer may continue to run for 5–10 seconds after the throttle is placed to off, then the engine will stop.

1. Turn the fuel valve to the “0” (open) position.

2. Open the throttle control lever to the “start” position.

3. Slowly pull the recoil starter rope handle until resis-

tance is met, then release.

4. Press down on the decompression lever. (When

pulling the recoil starter rope, the decompression lever will automatically return to initial position).

5. Quickly pull the recoil starter rope.

Switch off the engine as follows: CAUTION: Do not switch off engine by means of the decompression lever.

1. Reduce engine rpm’s and let it run for a short while.

CAUTION: Do not switch off engine directly from full power.

2. Shut off the engine by moving the throttle control lever

through the detent to the off position. The engine will stop.

3. Close the fuel valve.

Note: For short-term operation interruption, it is only necessary to stop the engine. 1027SD771A-11

1027SD81Note: If engine performance is poor, check, clean, and replace air filter elements as needed. (1) Perform initially after first 50 hours of operation.

• Run the rammer at the full throttle position for maxi- mum performance.

• Guide the rammer with its handle. Allow machine to pull itself forward. DO NOT try to over-power the machine.

The engine is equipped with a dual element air cleaner.1. Remove air cleaner cover (a). Remove precleanerand paper element and inspect them for holes ortears. Replace if damaged.2. Precleaner (b):Clean with low-pressure compressed air. When verysoiled, wash in solution of mild detergent and warmwater. Rinse thoroughly in clean water. Allow to drythoroughly before re-installing.Note: Do not oil precleaner.3. Paper element (c)Tap element lightly to remove excess dirt. Replacepaper element if it appears heavily soiled.4. Wipe out filter housing (d) with a clean rag.CAUTION: Do not allow dirt into the engine intake portwhile cleaning—damage to the engine will result. Under normal operating conditions the air cleaner elements will not require cleaning and should not be removed from the machine. If the elements do become plugged with dirt, the engine will begin to lose power. In this case, the elements can be removed and cleaned as described below. Replace an element if it becomes so plugged with dirt it can no longerbe cleaned. CAUTION: NEVER run engine without air cleaner. Severe engine damage will occur. NEVER use gasoline or other types of low flashpoint solvents for cleaning the air cleaner. A fire orexplosion could result. WARNING !1A-13

Engine oil Check oil level:Tilt the machine backwards approx. 15° until the engineis level by placing a wedge under the shoe. The oilsurface should reach NO HIGHER THAN the bottom of the filler neck “H”, but no lower than “L” (see drawing) or visible on the dipstick (f) when it is inserted (not screwed) into the filler neck.Add CC or better quality oil through the filler neck asrequired. CAUTION: DO NOT overfill. The oil level should just reach the bottom of the filler neck. Too much oil cancause damage to the engine and the rammer.Note: After transporting the rammer horizontally, upright the rammer and allow the oil to drain back through the engine. It may take up to 45 minutes for the oil level to recover. Oil filter:1. Drain the oil as above.
