The Mikasa MTR-60L 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.
NOTE
Narrow extension shoe
accessories are available from
MQ.
The impact force of the MTR-60L levels and uniformly compacts
voids between soil particles to increase dry density.
Circular motion is converted to create impact force. The MTR60L 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
GENERAL INFORMATION
The Mikasa MTR-60L Tamping Rammer is equipped with an
Robin air cooled, four 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 MTR-60L uses an grease lubrication system. Always
apply grease to all grease fittings every 8 hours of operation.
(Shell Darina EP2 or Equivalent).
Controls
Before starting the MTR-60L Tamping Rammer, identify and
understand the function of the controls, see Figure 1 on page 11.
Figure 1 shows the location of the controls and components
for the MTR-60L Tamping Rammer. The functions of each
control is described below:
1.Fuel Tank/Cap – Remove this cap to add fuel. Tank holds
.39 gallons (1.5 liters ) unleaded. Mix 32:1 ratio with
outboard motor oil.
2.Throttle Lever – Controls engine speed and the tamping
action of the rammer.
3.Handle – To operate rammer
firmly.
4.Fuel Shut-Off Valve – Supplies fuel from the fuel tank to
the engine. To begin fuel flow move the fuel shut-off valve
downward.
5.Choke Lever – Used when starting the engine. Normally
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.
6.Engine Air Cleaner – Prevents dirt and other debris
from entering the engine.
GRIP
handle assembly
8.Foot– Laminated wood with tempered steel plate for
superior shock absorption.
9.Fuel Valve – Open this valve to remove excess fuel from
the carburetor or crankcase.
10. Nameplate – Displays information regarding the rammer.
11. Muffler– Used to reduce noise and emissions.
12. Recoil Starting Handle – Used when starting the engine.
Pull starter handle sharply and quickly, then return
starter handle to starter case before releasing.
13. Engine Stop Switch – Controls the starting and stopping
of the engine. Switch must be in the "ON" position when
starting the engine.
14. Spark Plug – Provides spark to the ignition system,
replace with engine manufactures recommended type
spark plug.
7.Grease Fill Plugs – Grease these plugs to lubricate the
top and bottom mechanical component ends of the
rammer.
We strongly recommend that you study this Operational Manual.
