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.

feel a slight resistance. Then pull sharply and quickly. Return
the recoil starter handle to the starter case before releasing.
4. If engine fails to start, move the choke lever (Figure 3) to the
half open position to avoid flooding.
5. Repeat steps 1 thru 4.
6. If the engine does not start after repeated attempts,
check the spark plug for excess fuel. Clean and replace
the spark plug as needed.
7. If the carburetor is flooded or the crankcase is loaded
with fuel, open the drain plug as shown in Figure 7 and
drain excess fuel.

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.
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-75H Tamping rammer is designed to run at 4,000
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 MT-
75H 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.
Stopping The Engine

cools , turn the engine start/stop
switch to the “STOP” position (Figure 4) until engine comes
to a complete stop.
2. Close the fuel shut- off valve by moving the strainer lever
upward. See Figure 3.
Emergency Shutdown
2. Move the throttle lever quickly to the IDLE position, and turn
