OPERATION AND SAFETY DECALS

Definition of Tamping Rammer
The Mikasa MT-85H 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 MT-85H levels and uniformly compacts voids between soil particles to increase dry density.
Circular motion is converted to create impact force. The MT-85 H tamping rammer develops a powerful compacting force at the foot of the rammer. To maintain optimum performance, proper operation and service are essential.
Construction of Tamping Rammer
The Mikasa MT-85H is equipped with an air cooled, two cycle gasoline engine. Transmission of the power takes place by increasing the engine speed to engage the centrifugal clutch.
Rammer Gearbox and Spring Cylinder
The Mikasa MT-85H uses an oil bath lubrication system. Always check the oil level through the oil level sight glass at the rear of the tamper foot.
GENERAL INFORMATION
Controls
Before starting the MT-85H Tamping Rammer identify and understand the function of the controls, see Figure 1 on page 9.

CAUTION:CAUTION:
CAUTION:
CAUTION:CAUTION:
Failure to understand the operation of the MT­85H Tamping Rammer could result in severe damage to the trowel or personal injury.
Rammer Gearbox and Spring Cylinder Oil Bath
This unit uses an oil bath lubrication system. Perform the following:
1. Check the oil level through the oil level sight glass at the rear of the tamper foot.
2. If oil is not visible, add 10W-30 motor oil. The bath contains approximately 1.7 pints (800 cc.)
Inspection
1. Check all nuts, bolts fasteners for tightness. Retighten as necessary.
2. Clean any dirt from the recoil starter and foot pedestal. Wipe the entire unit clean before operating.
3. Replace any missing or damaged Safety Operation decals.
4. Adjust height of handle. Adjust handle by loosening nuts and moving handle to suit operation. Retighten nuts.
Initial Start-up
When starting the MT-85H Tamping Rammer perform the following:
1. Open the shut- off valve by moving the strainer lever
downward (Figure 3), then set the engine start /stop switch (Figure 4) to the "START" position.
NOTE
The oil level should be kept at the half way point of the sight glass.
Engine
Before pouring fuel into the fuel tank (Figure 2) perform the following:
1. Find a container for the mixing of fuel and gasoline.
2. Use a quality outboard motor oil for 2-cycle engines.
3. Mix gasoline (unleaded) with oil at a 25:1 ratio. Mix well.
4. Be sure to filter the mixed fuel with a strainer at the filler port.
5. If fuel spills on the fuel cap when operating rammer, replace the rubber leak stopper inside the cap.

2. Close the choke lever Figure 3 and move the throttle lever
to the "Full Open" position. Turning the choke lever 90 degrees clockwise closes the choke . In cold weather, start the unit with choke fully closed. In warm weather or when the engine is warm, the unit can be started with choke halfway or completely open.
Operation
1. To start the rammer tamping action, move the throttle lever
quickly from IDLE to the FULL OPEN position (Figure 5) . DO NOT move the throttle lever slowly as this may cause damage to the clutch or spring.

4. If engine fails to start, move the choke lever (Figure 3) to the
half open position to avoid flooding.
5. Repeat steps 1 thru 4.
6. If the engine does not start after repeated attempts,
check the spark plug for excess fuel. Clean and replace the spark plug as needed.
7. If the carburetor is flooded or the crankcase is loaded
with fuel, open the drain plug as shown in Figure 7 and drain excess fuel.
CAUTION:CAUTION:
CAUTION:
CAUTION:CAUTION:
2. The MT-85H Tamping rammer is designed to run at 4,000 rpm. At optimum rpm the foot hits at the rate of 665 impacts per minute. Increasing throttle speed past factory set rpm does not increase impacts and may damage unit. The MT­85H is designed to advance while tamping. For faster advance, pull back slightly on the handle so that rear of foot contacts soil first.
3. To stop the tamping action, move throttle lever quickly from the FULL OPEN to IDLE position.
Stopping The Engine
Normal Shutdown
1. Move throttle lever quickly from the FULL OPEN to IDLE position (Figure 5) and run the engine for three minutes at low speed. After the engine switch to the STOP position (Figure 4) until engine comes to a complete stop.
2. Close the fuel shut- off valve by moving the strainer lever upward. See Figure 3.
