2. Operation 2.1 Application Rammers are designed to compact loose soils and gravel to prevent settling and to provide a firm, solid base for the placement of footings, concrete slabs, foundations, gas piping works, water pipe works, and cable backfill works, etc. WARNING Please do not use in the following cases as it may cause damage because machine being unbalanced.
2.4 To Start 1. Open the fuel shut-off valve by moving the fuel cock level to the open position. 2. Set the engine ON/OFF switch to the “ON” position. 3. Grip the recoil starter handle and pull it until you feel slight resistance. Then pull sharply and quickly. Return the recoil starter handle to the starter case before releasing. 4. Grip the recoil starter handle and pull it a little to feel slight resistance. Then pull powerfully.
5. Soil contacting surface of the foot is lined with heat-treated metal sheet for extra strength. However, for compacting cobblestone, use the filling-up soil for example so that the foot hits the soil uniformly. 6. The tamping rammer has been designed to advance while jumping. For quicker advance, erect the machine by pushing its handle down slightly so that flat surface of the foot at its rear-end contacts the ground. 7.
3. Maintenance 3.1 Periodic Maintenance Schedule Daily before starting After first 5 hours Every Every 3 Every week or month or months or 25 hours 100 hours 300 hours Check fuel level Check oil level of machine Check fuel line and fittings for cracks or leaks.
3.2 Transporting 1. Shutdown engine for transportation 2. For transportation, tighten fuel tank cap securely and close fuel cock to prevent fuel from spilling. 3. Drain fuel for transportation over long distances or poor roads. 4. Secure machine firmly to prevent it from moving or tipping. 5. The rammer should be transported in the same position as if it is placed on level ground.
3.4 Air Cleaner A clean engine will extend engine life. Keep the air filter clean at all times. Clean the rammer’s air filter using the recommended solvent daily. See engine manual for proper cleaning procedure. Let the filter dry before reinstalling. NEVER use gasoline or other types of low flash point solvents for cleaning the air cleaner.

POSSIBLE CAUSES SOLUTION Ignition plug not properly connected? Check ignition system. Carbon deposit at ignition? Clean or replace ignition. Short circuit due to deficient insulator? Replace insulators. Improper spark plug gap? Set spark plug gap to the correct gap. Short circuit at stop switch? Check stop switch circuit.
POSSIBLE CAUSES SYMPTOM Not enough power available (compression normal, no misfiring) Engine overheats. Rotational speed fluctuates. Recoil starter malfunction. SOLUTION Ignition coil defective? Flush fuel system and replace fuel. Ignition plug often shorts? Replace ignition wires, clean ignition. Fuel is inadequate (water, dust)? Flush fuel system and replace fuel. Mixed fuel quality is inadequate? Check fuel to oil mixture.
