OPERATION
2 Operation
2.1 Application
Rammers are designed to compact various types of soil and clay to prevent
settling and provide a solid base for the placement of footings, concrete
slabs, foundations, gas lines, utility piping, etc.
Do not use in the following applications or scenarios as the rammer
is likely to become unbalanced and may cause operator injury or
machine damage.
Hard, over-compacted soil
Steep banks and slopes
Large piles of loose soil
2.2 Before Starting
Check the percussion system oil level through the sight glass located at the base of
the foot. Replenish oil if oil is not visible at the window. For lubrication, use
automobile engine oil of 10W-30 SE. Capacity is 28 oz.
Fill the fuel tank with regular gasoline (unleaded).
Check the in-line fuel filter for leaks or cracks and replace if necessary.
Check engine oil and replenish if necessary. Low lubrication oil level may result
in engine seizure due to consumption during operation. Use automobile engine
oil of 10W-30 SE. See Engine Operating Manual for further detail.
Inspect for any fuel or oil leaks. If present, repair prior to operation.
Check for any loose hardware. Hardware may loosen over time due to
compacting nature of the rammer. Tighten or repair as necessary.
Remove any dirt or dust accumulation, particularly around the engine, control area,
and ramming foot.

OPERATION
2.3 To Start
1. Slide the throttle lever from stop to the idle position.
2. Open the fuel shut-off valve by moving the fuel cock lever to the open position.
3. If starting the engine from cold, set the choke to the "CLOSED" position (If restarting
a warm engine, the choke is usually not required.)
4. Set the engine ON/OFF switch to the “ON” position.
5. Grip the recoil starter handle and pull it until you feel slight resistance. Then pull
sharply and quickly. Return the recoil starter handle to the starter case before
releasing.
6. As the engine warms, return the choke lever slowly to full-open position.
7. If engine fails to start, avoid engine flooding by moving the choke lever to the
half open position. Repeat above steps.
8. If engine still does not start, remove spark plug and check the sparking
performance. If the plug is wet due to excessive fuel intake or soiled, clean or
replace the coil as needed.

13
OPERATION
2.4 Operation
1. Allow engine to run for 5 minutes at low speed to warm the engine.
2. Move the throttle lever quickly to the “FULL OPEN” position. DO NOT move the
throttle level slowly as this may cause damage to the clutch or spring.
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.
3. Adjusting engine RPM outside the factory setting is NOT RECOMMENDED.
Increasing throttle speed will not increase the compaction force and may result in
machine damage.
4. Under cold weather, the oil in the machine being 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.
5. To stop the tamping action, move throttle lever quickly from the FULL OPEN to IDLE
position.
2.5 To Stop
2.5.1 Normal shutdown
1. Quickly move the throttle lever to the idle position and run the engine for 3-5
minutes at idle.
2. After engine temperature has cooled, turn the switch to the “OFF” position.
3. Close the fuel shut-off valve by moving the fuel cock lever to the CLOSED position.
2.5.2 Emergency shutdown
Move the throttle lever quickly to the IDLE position, and turn the engine ON/OFF switch
to the OFF position.
