MT-74FA — OPERATION AND SAFETY DECALS
Machine Safety Decals
The MQ Mikasa tamping rammer is equipped with a number of safety decals. These decals are provided for operator safety and
maintenance information. Figure 1 and 1A below and preceeding page illustrates these decals as they appear on the machine.
Should any of these decals become unreadable, replacements can be obtained from your dealer.

MT-74FA — GENERAL INFORMATION
Definition of Tamping Rammer
The Mikasa MT-74FA 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.
CAUTIONCAUTION
CAUTION
CAUTIONCAUTION
Before starting operation check the lifting
handle to:
Handle Operation
The impact force of the MT-74FA levels and uniformly compacts
voids between soil particles to increase dry density.
Circular motion is converted to create impact force. The MT-74FA
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-74FA is equipped with an air-cooled, 4-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-74FA uses an oil bath lubrication system. Always
check the oil level through the oil level sight glass at the rear of
the tamper foot.
Controls
Before starting the MT-74FA Tamping Rammer, identify and
understand the function of the controls. See Figure 2.
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 there
is any abnormality or damage, replace with new one.
For operation:
This handle is to be used to lift up the shoe part of the machine
with the body laid down on the ground or truck bed.
1. Use proper lifting techniques to avoid back injury. This
handle is for manual lifting only.
2. Do not use this handle as a rammer lift point. Use the
lifting point on the top of the machine.
3. Do not move the rammer with the lifting handle and the
front rollers more than (16 feet) 5 meters.

WARNING
used in cold weather conditions. In cold weather turn the
choke lever to the fully closed position, in warm weather
set choke lever half way or completely open.
3. Spark Plug – Provides spark to the ignition system. Set
spark plug gap to 0.6 - 0.7 mm (0.024 - 0.028 inch). Clean
spark plug once a week.
4. Muffler – Used to reduce noise and emissions.
WARNING
5. Recoil Starter (pull rope) – Manual-starting method. Pull
the starter grip until resistance is felt, then pull briskly and
smoothly.
6. Engine ON/OFF Switch – Controls the starting and
stopping of the engine. Switch must be in the "ON" position

MT-74FA — OPERATION
This section is intended to assist the operator with the initial
start-up of the MT-74FA Tamping Rammer. It extremely important
that this section be read carefully before attempting to operate
the rammer.
DO NOT use your rammer until this section is thoroughly
understood.

CAUTION
CAUTICAUTI
Failure to understand the operation of
the MT-74FA 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 (Figure 4)
at the rear of the tamper foot.
Read Manual
Engine
1. Fill the fuel tank (Figure 5) with unleaded gasoline. At the
same time, check the engine oil and make it a habit to
replenish it often.
Figure 5. Fuel Tank
2. Low levels of oil may result in engine seizure due to high
levels of consumption during operations.
Figure 4. Foot Housing Sight Glass
2. If oil is not visible, add 10W-30 motor oil into the oil fill plug
opening (Figure 4). The bath contains approximately 0.8
pints (0.4 liters)
NOTE
The oil level should be kept at the half
way point of the sight glass.
PAGE 16 — MT-74FA — OPERATION AND PARTS MANUAL — REV. #3 (11/08/07)
3. Check the engine oil level and if the engine oil level is low, it
should be refilled. Use the proper motor oil as suggested in
the Table 3 below.

the spark plug as needed.
MT-74FA — OPERATION
Operation
1. To start the rammer tamping action, move the throttle lever
(Figure 11) quickly from IDLE (close) to the FULL OPEN
position . DO NOT move the throttle lever slowly as this may
cause damage to the clutch or spring.
Stopping The Engine
Normal Shutdown
1. Move throttle lever quickly from the FULL OPEN to IDLE
position (Figure 12) and run the engine for three minutes at

CAUTION:CAUTION:
CAUTION:
CAUTION:CAUTION:
Make sure that the throttle lever is moved to the
FULL OPEN position. Operating the rammer at
less than full speeds can result in damage to
the clutch springs or foot
2. The MT-74FA tamping rammer is designed to run at 4,000
rpm. At optimum rpm the foot hits at the rate of 680 impacts
per minute. Increasing throttle speed past factory set rpm
does not increase impacts and may damage unit. The
MT-74FA 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.
