OPERATION AND SAFETY DECALS

Definition of Tamping Rammer
The Mikasa MT-75H 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-75H levels and uniformly compacts
voids between soil particles to increase dry density.
Circular motion is converted to create impact force. The MT-75 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-75H 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-75H 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-75H Tamping Rammer identify and
understand the function of the controls, see Figure 1 on page 9.

Failure to understand the operation of the MT75H 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

moving handle to suit operation. Retighten nuts.
Initial Start-up
When starting the MT-75H 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 swi tch
(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.

rpm. At optimum rpm the foot hits at the rate of 690 impacts
per minute. Increasing throttle speed past factory set rpm
does not increase impacts and may damage unit. The MT75H 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.
