cloth rags, or other flammable materials.
c. Keep the engine at least 3 feet (1 meter)
away from buildings or other structures.
d. Keep the engine away from flam-males
and other hazardous materials (trash, rags, lubrications,
explosives).
e. The muffler becomes very hot during
operation and remains hot for a while
after stopping the engine. Be careful not
to touch the muffler while it is hot. Let
the engine cool before storing it indoors.
5. The max gradient of 30° must not be
exceeded when the engine working. Otherwise, the fuel will spilt and
the engine oil into the cylinder, causing engine failure or other
hazards.

9. Placed a machine, we should avoid dumping, roll and fall, etc.
TRANSPORTING AND STORAGE
DANGER! Keep the engine lever off when transporting to reduce the
possibility of fuel leakage. Turn the fuel valve lever to the OFF position.
1. Keep the fuel valve lever to OFF position
when transporting.
2. The load-carrying capacity of the loading
ramps has to be sufficient and the ramps have
to be secured such that they cannot turn over.
Make sure that no one be endangered by
machines turning over by slipping or by moving machine parts.
3. Drain the used oil when being transported on vehicles, precautions
have to be taken that vibration plates do not slip or turn over.
The following should be taken to prepare your
TRE-85 Tamping Rammer for extended storage.
1、Close fuel shut off valve.
2、Store the unit in an upright position in a cool, dry,
well ventilated area.
3、Discharge fuel (NO SMOKING!)
a. Remove the strainer cup, place the strainer
over a container and open the strainer cock to
discharge fuel from the fuel tank.
b. Remove the carburetor float chamber bolt from
the bottom and discharge fuel from the
carburetor.

- 7 -
4、Engine oil
a. Change the engine oil fresh oil (see page 10).
b. Remove the spark plug, pour about 5cc of engine oil into the
cylinder, slowly pull the starter handle of the recoil starter 2 or 3
times, and reinstall the spark plug.
5、Clean and store
a. Slowly pull the recoil starter handle until resistance is felt and
leave it in that position.
b. Clean the engines thoroughly with an oiled cloth, put the cover on,
and store the engine indoors in a well-ventilated, low humidity
area.
BEFORE OPERATION CHECKS
1. Check for leakage of gasoline and engine
oil.
2. Check engine oil
Notice! Running the engine with a low oil
level can cause engine damage.
a. Before checking or refilling engine oil, be sure the rammer is located
on a stable, level surface and stopped.
b. Remove the filler cap/dipstick and check
the oil level shown on the dipstick.
c. If the oil level is low, fill to the edge of the
oil filler hole with the recommended oil.
Oil capacity: 0.4L
SAE 10W-30 is recommended for general
use. Other viscosities shown in the chart
may be used when the average temperature in your area is with the
recommended range.
CAUTIONS! Use not depurative lubrication or 2-cycle lubrication can

- 8 -
cause engine damage.
3. Check air cleaner
NOTICE! Operating the engine without an air filter, or with a damaged air
filter, will allow dirt to enter the engine, causing rapid engine wear. This
type of damage is not covered by the Distributor’s Limited Warranty.
4. Check fuel
These engines are certified to operate on unleaded gasoline. Unleaded
gasoline produces fewer engine and spark plug deposits and extends
exhaust system life. Never use stale or contaminated gasoline or an oil
/gasoline mixture. Avoid getting dirt or water in the fuel tank. Occasionally
you may hear a light “spark knock” or “pinging” (metallic raping noise)
while operating under heavy loads. This is no cause for concern. If spark
knock or pinging occurs at a steady engine speed, under normal load,
change brands of gasoline. If spark knock or pinging persists, see an
authorized you’re servicing dealer.
DANGER!
a、Gasoline is highly flammable and explosive.
b、Refuel in a well-ventilated area before starting the engine. If the
engine has been running, allow it to cool. Gasoline is highly
flammable and explosive.
c、Refuel carefully to avoid spilling fuel. Do not fill the fuel tank
completely. Fill tank to approximately 1 inch (25mm) below the
top of the fuel tank to allow for fuel expansion. It may be
necessary to lower the fuel level depending on operating
conditions. After refueling, tighten the fuel tank cap securely.
d、Be careful not to spill fuel when filling your fuel tank. Damage
caused by spilled fuel is not covered under warranty.
e、Spilled fuel is not only a fire hazard, it causes environmental
damage. Wipe up spills immediately.
f、Keep the children away from the fuel.
