Familiarity and proper training are required for the safe operation of equipment! Equipment operated improperly or by untrained personnel can be dangerous! Read the operating instructions contained in both warning this manual and the engine manual and familiarize yourself with the location and proper use of all controls. Inexperienced operators should receive instruction from someone familiar with the equipment before being allowed to operate the machine.
Operator Safety while using Internal Combustion Engines • Do not smoke when refueling engine. • Do not refuel hot or running engine. • Do not refuel engine near open flame. • Do not spill fuel when refueling engine. • Do not run engine near open flames. • Do not run machine indoors or in an enclosed area such as a deep trench unless adequate ventilation. • ALWAYS refill fuel tank in well-ventilated area. • ALWAYS check fuel lines and fuel tank for leaks and cracks before starting engine.
1. For new or long storage machines, oil sealed in the cylinder must be removed first. The removing method: Take off the spark plug, use the lift thumb to stop the spark plug hole and pull the starter with strength to spray the oil out. 2. Check the sparks of the spark plug. Normally the sparks should be blue. 3. Check if the air cleaner is clean. Dirty air cleaner will influence the volume of incoming air that can cause the bad performance of the engine. 4.
Place throttle in the idle position (c2). Shut off the engine by moving the throttle through to the off position (c1). The engine will stop and the fuel valve will close. If the throttle control wire should break, keep pressing the stop button (d) until the engine stops completely (Fig. 1). The sudden stoppage of the engine during high-speed operation may cause the engine trouble; therefore, avoid it except for the emergency case. Operation Keep vibratory rammer clean and dry. Avoid no-load strokes.
Run rammer at the full throttle position (a4) for maximum performance (Fig. 3). Guide rammer with its handle. Allow machine to pull itself forward. DO NOT try to over-power the machine. For best compaction, the shoe must hit the ground flat (b), not on its toe or heel. This will save on excessive shoe wear.
Fuel system maintenance Water or dirt in fuel is one of the main cause of the engine trouble, clean the fuel system regularly. Residual fuel remaining in the fuel tank and carburetor for long time will gum and clog the fuel system, thus cause the engine not to working properly. So all of the fuel should be discharged if the machine isn’t used after one week. NEVER use gasoline or other types of low flash point solvents for cleaning the air cleaner. A fire or explosion could result.
CAUTION: NEVER run engine without air cleaner. Severe engine damage will occur. The rammer is equipped with a dual element air cleaner. Under normal operating conditions, elements should be cleaned once every week. Under severe, dry and dusty conditions, the elements should be maintained daily. Replace an element when saturated with dirt that cannot be removed. Clean elements using the following procedure. (1) Remove air cleaner cover (a).
Change ramming system oil after first 50 hours of operation and every 300 hours thereafter. To drain oil, remove plug (g) and tilt machine back until it is resting on handle (Fig. 6). Fig. 6 Note: In the interests of environmental protection, place a plastic sheet and a container under the machine to collect any liquid which drains off. Dispose of this liquid in accordance with environmental protection legislation. With the rammer on a level surface, add oil through plug.
CAUTION: DO NOT turn the adjusting screw in too tight or you may damage the carburetor. Long time storage Clean the machine and apply anti-rust oil to metal parts. Remove the chemical tank, clean the dust gate and inside and outside of chemical tank, then install the tank and leave the lid loose. Discharge fuel in the tank and carburetor entirely. Cover the machine with plastic dust coat and store it in a dry and clean place.
