MTR-80L OPERATION
1. Characteristics
The Mikasa rammer is a well- constructed, quiet, low
maintenance rammer designed to do the perfect confined area
compaction job.
The MTR-80L is used primarily to compact all
types of soils and is used in all types of construction.
2. Construction
The rammer is powered by a two-cycle air cooled gasoline
engine.
Power is transmitted from the engine by increasing the
engine speed through a centrifugal clutch to pinion gear. The
rotary motion of the engine is converted to a vertical up and
down motion mechanism which is connected to a guided shoe.
3. Before Operation
3.1 If a cart is supplied, remove the tamping rammer from the
two-wheel dolly cart. Make sure the rammer stands steady and
does not fall over as damage may result.
3.2 Grease the tamping rammer with a hand gun before
operating. CAUTION: DO NOT USE A POWER OPERATED
GREASE GUN AS DAMAGE MAY RESULT. There are six (6)
lubrication points on the rammer. Three are located on the rear
head and three on the bottom part of the machine. Give each
grease fitting five (5) shots of grease. Be sure to use MQ HIGH
TEMPERATURE GREASE (PART #GRS2). If an inferior type
grease is used, the grease could become too thick or too thin
due to change in temperature and improper lubrication may
result.
GOVERNOR LUBRICATION. Remove the oil plug, located on
the top of the engine crank case, and pour in the proper amount
of motor oil.
(Summer: SAE #30; Winter: SAE #20). MTR-80L:
60cc (1-11/16 OZ.)
3.3 Fill the fuel tank with a fuel mixture of gasoline and oil. Use
a well-blended mixture of 32 parts gasoline to one part motor
oil.
A regular grade gasoline should be used. High test ethyl
gasoline is not recommended. Use any good quality outboard,
two-cycle, or equivalent motor oil. IMPORTANT: For the first 20
hours of initial use, a mixture of 20 parts gasoline to one part
motor oil must be used.
When filling the rammer with fuel, be
sure the filter (#112P19) is in place. Also make sure that the
leak stopper (#159P19) is in the tank cap as the fuel will splash
out through the vent hole in the cap when the rammer is
operating.
3.4 Check all the screws and bolts for tightness. Vibration can
cause screws and bolts to loosen, therefore periodically check
for tightness to avoid problems.
3.5 Brush away dust from the following places: the wire gauze
of the recoil starter; and guide spindle by removing the dust
protection sleeve; and from the foot.
Dust and dirt restrict proper
lubrication and may cause excessive wear.
3.6 Adjust the height of the handle in accordance with the
operator. The side handle is designed to be adjusted with ease
by loosening the nuts.
4. Starting the Engine
4.1 Open the fuel cock assembly (#116AP19) on lower left side
of fuel tank by moving the lever downward.
4.2 Close the choke lever of the carburetor and move the throttle
lever of the handle to the “OFF” position. For cold engine
starting, move the choke lever all the way up to the closed
position.
When the engine is warm, the choke should be half
open. If you have difficulty in starting the engine, make sure the
choke is in the half open position to prevent flooding the
carburetor with fuel.
4.3 Crank the engine by pulling the grip of the recoil starter
towards you and release.
4.4 When the engine starts, gradually move the choke lever
back to full open position.
4.5 Allow the engine to warm up for 3 to 5 minutes before
operating. This allows the lubricating oil to fully circulate and
cover all engine parts.
4.6 If the engine will not start, remove and check the spark plug.
If the spark plug is wet or dirty, clean it or replace the spark plug.
After removing the spark plug, discharge any excess fuel by
cranking the engine two or three times by hand.
If the engine is
flooded, open the fuel discharge cock located at the lower of
part the crankcase and discharge the fuel by cranking the engine
two or three times.
Too much fuel in the crankcase will prevent
the engine from running smoothly.
5. Operation
5.1 Move the throttle lever on the handle quickly from the “OFF”
to the “ON” position, and the tamping rammer starts operating.
CAUTION: Do not move the lever slowly as slow movement will
cause irregular operation and may damage the clutch, springs,
or foot.
5.2 After starting the rammer, adjust the tamping pressure in
accordance with the soil conditions by adjusting the throttle
lever.
As a general rule, fast tamping is used on soft ground and
slower tamping on hard ground. The foot of the rammer is
designed to tamp the ground 600 to 650 times per minute with
an engine speed of 3,800-4,000 rpm.
The machine will work
most efficiently in this range. An increase in the engine
revolutions will not always increase the tamping pressure.
