speed unnecessarily, does not cause the compaction
force to increase. On the contrary, a resultant resonance
causes the compaction force to decrease, damaging
the machine.
Under cold weather, the oil in the machine being
4
viscous, resistance at reciprocating part is greater
causing the tamping rammer to perform somewhat
irregular movement. Therefore, it is recommended to
perform warm-up run while moving the throttle lever
repeatedly between ON and OFF positions, before
entering the work.

Soil contacting surface of the foot is lined with heat-
treated metal sheet for extra strength.
However, for compacting cobblestone, use the
filling-up soil for example so that the foot hits the soil
uniformly.
Air Cleaner Cleaning for MR68H/MR75R (6 to 12
months Service): Remove element from pre-cleaner
at the top of crank case and clean it with cleaning
oil (kerosene). Take of 'Bolt, Cover' of the crankcase
upper part and take 'Element' off 'AIR CLEANER'. Wet
the bottom element (gray) with 7-9cc and let upper
element (yellow) be familiar with oil. MR75R is the top
element (yellow) with 2-5cc and bottom element (gray)
with 13-15cc of engine oil SAE 10W-30 squeeze out
the oil before installing them. Air cleaner of the engine
side will hardly be contaminated. If it is, however, after
cleaning the element with kerosene, dip it in mixed oil
consisting of 3 parts of gasoline and 1 part of engine oil.
Then tightly squeeze outer primary element (sponge)
and shake off well the inner secondary element before
installing them.

MANTENIMIENTO Y ALMACENAMIENTO
The tamping rammer has been designed to advance
while jumping. For quicker advance, erect the machine
by pushing its handle down slightly so that flat surface
of the foot at its rear-end contacts the ground.
To stop the tamping action, move throttle lever quickly
from the FULL OPEN to IDLE position.
Apagado
Apagado Normal
With the throttle lever closed from ON to OFF, run
the engine for 3-5 minutes at low speed, and after
temperature is lowered, turn the switch to the "OFF"
position.
Close the fuel shut-off valve by moving the fuel cock
lever to the CLOSED position.
Apagado de emergencia
Move the throttle lever quickly to the IDLE position, and
turn the engine ON/OFF switch to the OFF position.
Storage
Rammer should be stored in such position as it is placed
on level, after engine and machine have been cooled
down. Be sure to secure the rammer as necessary to
avoid falling down. If the rammer has to be laid down
inevitably, tighten fuel tank cap and engine oil plug
securely and wait until engine and machine are cooled
down. After laying it down, make sure that there is no
leak of fuel or oil. (If fuel leaks, drain the tank)
Long-Term Storage
Drain fuel from fuel tank, fuel line and carburetor.
Remove spark plug and pour a few drops of motor oil into
cylinder. Crank engine 3 to 4 times so that oil reaches all
internal parts. Clean exterior with a cloth soaked in clean
oil. Store unit covered with plastic sheet in moisture free
and dust free location out of direct sunlight.
