ENGLISH

v.211220 | 9
SAFETY
SAFE PRACTICES & GENERAL INFORMATION
• Avoid wearing loose fitting clothing or jewelry, which can catch on moving parts.
• We recommend wearing gloves while operating the machine. Be sure your gloves fit
properly and DO NOT have loose cus or drawstrings.
• Wear shoes with non-slip treads when using your machine. If you have safety shoes, we
recommend wearing them. DO NOT use this machine while barefoot or wearing open-toed
footwear.
• Wear long pants while operating the machine.
• Always keep bystanders at least 50 feet away from your work area. Stop the engine when
another person or pet approaches.
WARNING: SAFETY FOR CHILDREN AND PETS
Tragic accidents can occur if the operator is not alert to the presence of children and pets.
Children are often attracted to the machine and its activity. Never assume that children will
remain where you last saw them. Always follow these precautions.
• Keep children and pets at least 50 feet from the working area and ensure they are under the
watchful care of a responsible adult.
• Be alert and turn the machine o if children or pets enter the work area.
• Never allow children to operate the machine.
WARNING: SAFETY WITH GASOLINE
Gasoline is a highly flammable liquid. Gasoline also gives o a flammable vapor that can be
easily ignited and cause a fire or explosion. Never overlook the hazards of gasoline. Always
follow these precautions.
• Never run the engine in an enclosed area or without proper ventilation as the exhaust from
the engine contains carbon monoxide, which is an odorless, tasteless, and deadly poisonous
gas.
• Store all fuel and oil in containers specifically designed and approved for this purpose and
keep away from heat and open flame.
• Replace rubber fuel lines and grommets when worn or damaged and after 5 years of use.
• Fill the gasoline tank outdoors with the engine o and allow the engine to cool completely.
Don’t handle gasoline if you or anyone nearby is smoking, or if you’re near anything that
could cause it to ignite or explode. Reinstall the fuel tank cap and fuel container cap
securely.
• If you spill gasoline, DO NOT attempt to start the engine. Move the machine away from
the area of the spill and avoid creating any source of ignition until the gas vapors have
dissipated. Wipe up any spilled fuel to prevent a fire hazard and properly dispose of the

waste.
• Allow the engine to cool completely before storing in any enclosure. Never store a machine
that has gas in the tank, or a fuel container, near an open flame or spark such as a water
heater, space heater, clothes dryer, or furnace.
• Never adjust or repair with the engine running. Shut down the engine, disconnect the spark
plug wire, keeping it away from the spark plug to prevent accidental starting, wait 5 minutes
before adjusting or repairing.
• Never tamper with the engine’s governor setting. The governor controls the maximum safe
operation speed and protects the engine. Over-speeding the engine is dangerous and will
cause damage to the engine and to the other moving parts of the machine. If required, see
your authorized dealer for engine governor adjustments.
• Keep combustible substances away from the engine while it is hot.
• Never cover the engine while the muer is still hot.
 DO NOT operate the engine with the air cleaner or the carburetor air intake cover removed.
Removal of such parts could create a fire hazard. DO NOT use flammable solutions to clean

ENGLISH

18 | OPV425 man.
STARTING THE ENGINE
1. Open the fuel valve by moving the lever to the right (a1).
2. Turn the engine switch to the ON position (e1).
3. Open the throttle by moving it slightly to the left (d1).
4. Pull the starter rope (c).
5. Open the choke as the engine warms (b2).
6. Open the throttle fully to operate.
NOTE: If the engine is cold, move the choke lever to the CLOSE position (b1). If the engine is
hot, set the choke to the OPEN position (b2).

OPERATION
STARTING THE ENGINE
ENGLISH

v.211220 | 19
OPERATION
STARTING THE ENGINE
NOTE: Whenever high-speed operation (over 3,600 RPM) is NOT required, slow the engine
by moving the speed control lever to a low position to save fuel and extend the life of the
equipment.
7. Once the engine has started, firmly grasp the plate compactor’s handle bar with one hand
then quickly turn the throttle lever to high speed. The engine speed should be around 2,300
RPM therefore engaging the centrifugal clutch.
NOTE: Always move the throttle lever quickly without hesitation, because increasing the
engine speed slowly will cause the clutch to slip.
8. Firmly grasp the plate compactor’s handle bar with both hands as it begins to move forward.
Walk behind the unit watching for any large objects or foreign matter that might cause
damage to the compactor or shoot out causing property damage or bodily injury. If objects
are in the travel path, slow the engine (stopping compactor travel) and remove the object
before proceeding.
The compactor’s travel speed may slow down on soils that contain clay; however, there may
be cases where the travel speed slows because the vibrator/compaction plate does not
leave the ground surface easily due to the composition of the soil. To correct this problem:
• With the compactor turned o completely and the engine cooled, check the vibrator
plate to see if clay or other materials have been lodged in the mechanism. If so, clean the
plate mechanism with water and remove the material.
• Remember that the plate compactor does not work eciently on clay or very moist soil.
• If the soil is very moist, dry it to a suitable level or perform compaction twice.
ENGLISH

20 | OPV425 man.
OPERATION
STOPPING THE ENGINE
STOPPING THE ENGINE
CAUTION: Never stop the engine abruptly from full speed. Slow the speed and
allow the engine to run idle for a few minutes. This is necessary to prevent the
moisture of the outside air from getting into the engine carburetor.
• Slow the engine to idle by turning the accelerator lever fully counter-clockwise.
• Shift the engine ON/OFF switch to the OFF position.
• Close the fuel valve.
See the engine’s owner’s manual for further information about your engine.
