general Information The Multiquip MTX80SD 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 MTX80SD levels and uniformly compacts voids between soil particles to increase dry density. Circular motion is converted to create impact force.
components 3 2 10 4 1 5 9 6 11 7 12 13 8 Figure 1. MTX80SD Rammer Figure 1 shows the location of the controls and components for the MTX80SD Tamping Rammer. The functions of each control is described below: 1. Combination (Throttle) Lever — Used to adjust engine speed (rpm). Move lever forward (SLOW) to reduce engine speed, move lever back toward operator (FAST) to increase speed. Always operate the rammer at full speed (rpm). 2. Handle — To operate rammer, GRIP handle assembly firmly on both sides.
basic engine Figure 2. Robin ER120D45000 Engine The engine (Figure 2) must be checked for proper lubrication and filled with fuel prior to operation. Refer to the engine manufacturer's manual for detailed operation and service information. 1. Choke Lever — Normally used in starting the engine in cold weather conditions.
