SAFETY INFORMATIONENGINE SAFETYDANGER The engine fuel exhaust gases contain poisonous carbonmonoxide. This gas is colorless and odorless, and cancause death if inhaled.FUEL SAFETYDANGER DO NOT add fuel to equipment if it is placed inside truckbed with plastic liner. Possibility exists of explosion orfire due to static electricity. The engine of this equipmentrequires an adequate free flowof cooling air. NEVER operatethis equipment in any enclosedor narrow area where free flowof the air is restricted. If the airflow is restricted it will causeinjury to people and propertyand serious damage to theequipment or engine.WARNING DO NOT place hands or fingers inside enginecompartment when engine is running. NEVER operate the engine with heat shields orguards removed. DO NOT remove the engine oil drain plugwhile the engine is hot. Hot oil will gushout of the oil tank and severely scald anypersons in the general area of the rammer.CAUTION NEVER touch the hot exhaust manifold,muffler or cylinder. Allow these parts to coolbefore servicing equipment.NOTICE NEVER run engine without an air filter or with a dirty airfilter. Severe engine damage may occur. Service air filterfrequently to prevent engine malfunction. NEVER tamper with the factory settingsof the engine or engine governor. Damageto the engine or equipment can resultif operating in speed ranges above themaximum allowable. DO NOT start the engine near spilled fuel or combustiblefluids. Fuel is extremely flammable and its vapors cancause an explosion if ignited. ALWAYS refuel in a well-ventilated area, away fromsparks and open flames. ALWAYS use extreme caution when working withflammable liquids. DO NOT fill the fuel tank while the engine is runningor hot. DO NOT overfill tank, since spilled fuel could ignite if itcomes into contact with hot engine parts or sparks fromthe ignition system. Store fuel in appropriate containers, in well-ventilatedareas and away from sparks and flames. NEVER use fuel as a cleaning agent. DO NOT smoke around or near theequipment. Fire or explosion could resultfrom fuel vapors or if fuel is spilled on ahot engine.PAGE 8 — MTX80/90 RAMMER — OPERATION AND PARTS MANUAL — REV. #9 (1/14/11)

GENERAL INFORMATIONDefinition of Tamping RammerThe Mikasa MTX80/MTX90 tamping rammer is a powerfulcompacting tool capable of applying a tremendous force inconsecutive impacts to a soil surface. Its applications includesoil compacting for road, embankments and reservoirs aswell as backfilling for gas pipelines, water pipelines and cableinstallation work.The impact force of the MTX80/MTX90 levels and uniformlycompacts voids between soil particles to increase dry density.Circular motion is converted to create impact force. TheMTX80/MTX90 tamping rammer develops a powerfulcompacting force at the foot of the rammer. To maintainoptimum performance, proper operation and service areessential.Construction of Tamping RammerThe Mikasa MTX80/MTX90 is equipped with an air cooled,four- cycle gasoline engine. Transmission of the power takesplace by increasing the engine speed to engage thecentrifugal clutch.Rammer Gearbox and Spring CylinderThe Mikasa MTX80/MTX90 uses an oil bath lubricationsystem. Always check the oil level through the oil level sightglass at the rear of the tamper foot.Handle OperationCAUTIONBefore starting operation check the liftinghandle to:1. Make sure that there is no damage on the bolts.2. Make sure that there is no crack or breakage on handle.3. Make sure that there is no fissure on the surface. If thereis any abnormality or damage, replace with new one.For operation:This handle is to be used to lift up the shoe part of the machinewith the body laid down on the ground or truck bed.1. Use proper lifting techniques to avoid back injury. Thishandle is for manual lifting only.2. Do not use this handle as a rammer lift point. Use thelifting point on the top of the machine.3. Do not move the rammer with the lifting handle and thefront rollers more than 16 feet (5 meters).ControlsBefore starting the MTX80/MTX90 Tamping Rammer identifyand understand the function of the controls.PAGE 10 — MTX80/90 RAMMER — OPERATION AND PARTS MANUAL — REV. #9 (1/14/11)

BASIC ENGINEFigure 2. Engine Controls and Components(Robin EH-12-2D)The engine (Figure 2) must be checked for proper lubricationand filled with fuel prior to operation. Refer to the manufacturer'sEngine manual for instructions & details of operation andservicing.1. Secondary Air Cleaner – Prevents dirt and other debrisfrom entering the fuel system. Remove wing-nut on topof air filter cannister to gain access to filter element.2. Choke Lever – Used when starting the engine. Normallyused in cold weather conditions. In cold weather turnthe choke lever to the fully closed position, in warmweather set choke lever half way or completely open.3. Spark Plug – Provides spark to the ignition system.Set spark plug gap to 0.024 - 0.028 inch (0.6 - 0.7 mm).Clean spark plug once a week.4.5.6.Muffler – Used to reduce noise and emissions.Recoil Starter (pull rope) – Manual-starting method.Pull the starter grip until resistance is felt, then pullbriskly and smoothly.Engine ON/OFF Switch – Controls the starting andstopping of the engine. Switch must be in the "ON"position when starting the engine.WARNINGEngine components can generate extremeheat.To prevent burns, DO NOT touch theseareas while the engine is running orimmediately after operating. NEVER operatethe engine with the muffler removed.NOTICEOperating the engine without an air filter, with a damaged airfilter, or a filter in need of replacement will allow dirt to enterthe engine, causing rapid engine wear.MTX80/90 RAMMER — OPERATION AND PARTS MANUAL — REV. #9 (1/14/11) — PAGE 13
