general Information Definition of Tamping Rammer The Multiquip MTX70HF tamping rammer is a powerful compacting tool capable of applying a tremendous force in consecutive impacts to a soil surface. Its applications include soil compacting for road, embankments and reservoirs as well as backfilling for gas pipelines, water pipelines and cable installation work. The impact force of the MTX70HF levels and uniformly compacts voids between soil particles to increase dry density.

Initial Startup When starting the MTX70HF Tamping Rammer perform the following: 1. Slide the throttle lever from the stop to the idle position ( ) (Figure 6).
operation operation Stopping The Engine 1. To start the rammer tamping action, move the throttle lever (Figure 9) quickly from IDLE to the START ( ) position. DO NOT move the throttle lever slowly as this may cause damage to the clutch or spring. 1. Move throttle lever quickly from the START to IDLE position (Figure 6) and run the engine for three minutes at low speed. After the engine cools, move the throttle lever to the STOP position (Figure 10).
maintenance Perform the scheduled maintenance procedures as indicated: DAILY Thoroughly remove dirt and oil from the engine and control area. Clean or replace the air cleaner elements as necessary. Check and retighten all fasteners as necessary. Check the spring box and bellows for oil leaks. Repair or replace as needed. EVERY 50 HOURS PRIMARY ELEMENT Figure 12. Air Cleaner Primary Element EVERY 200 HOURS Remove the fuel filter cap and clean the inside of the fuel tank (Figure 11).
troubleshooting Troubleshooting (engine) symptom possible problem solution Spark plug bridging? Check gap, insulation or replace spark plug. Carbon deposit on spark plug? Clean or replace spark plug. Short circuit due to deficient spark plug insulation? Check spark plug insulation, replace if worn. Improper spark plug gap? Set to proper gap. Fuel reaching carburetor? Check fuel line. Water in fuel tank? Flush or replace fuel tank. Fuel filter clogged? Replace fuel filter.
troubleshooting Troubleshooting (engine) - continued symptom Weak in power, compression is proper and does not misfire. Weak in power, compression is proper but misfires. Engine overheats. Rotational speed fluctuates. Recoil starter malfunctions. (if applicable) Starter malfunctions. possible problem Air cleaner dirty? Clean or replace air cleaner. Improper level in carburetor? Check float adjustment, rebuild carburetor. Defective spark plug? Clean or replace spark plug.
troubleshooting symptom Engine runs but rammer jumps erratically or not at all. Troubleshooting (Rammer) possible problem Operating speed of throttle lever is incorrectly set? Oil in excess? Clutch slips? Spring Failure? Speed of engine improper? Soil over-compacted? solution Set throttle lever to correct position. Drain excess oil. Bring to correct level. Replace or adjust clutch.
