4.3 PRE-OPERATION CHECKS
CAUTION: Sections on Engine Maintenance, Lubrication and Air Cleaner must be followed exactly.
Failure to follow these instructions may void the warranty.
4.3.1 Engine Checks
DIESEL ENGINE: Diesel fuel is mandatory for use in this engine. Always use clean fuel. Low quality or
contaminated fuel will damage fuel injection components.
DIESEL FUEL STORED IN GALVANIZED CONTAINERS REACTS CHEMICALLY
WITH THE ZINC COATING ON THE CONTAINER. THE CHEMICAL REACTION
CREATES POWDERY FLAKES OF ZINC SULFIDE. IF WATER IS PRESENT IN THE
FUEL, A ZINC HYDROXIDE GEL WILL FORM.
Periodic checks and maintenance are required to keep your unit running properly.
l
Fuel Use Diesel Fuel only. Strain the fuel through a fine meshed screen when filling fuel
tank on engine to remove dirt if present.
l
Lube Oil Check crankcase oil level daily. Fill to proper level with SAE 15W 40 CC/CD
oil of API engine service application.
l
Replace Oil Engine oil should be changed after first 20 hours then every 100 hours thereafter.
l
Adjustment Check and tighten engine parts daily. Clean engine cooling fins daily. Check and
adjust valves every 300 hours. Clearance to be set at 0.15 mm while engine is
cold.
OPERATING INSTRUCTIONS
4.2 OPERATING PRINCIPLE
A tamping shoe is mounted at the lower end of a cylindrical spring housing. A piston, installed between
massive opposing springs inside the spring housing, is actuated by a connecting rod and crank system
which is driven by a powerful air-cooled 4 hp diesel engine through a gear train and centrifugal clutch.
The piston alternately loads and unloads the springs. This results in a rapid lifting up and ramming down
action of the tamping shoe to compact the underlying material.
The Stomper is effective for compaction of a wide variety of job soil substances, particularly clay lumps,
silt, loam and all granular materials. Although relatively light in weight and easy to operate, the Stomper
delivers a tremendous impact to the soil.
These instructions contain information to guide you in efficient use and proper maintenance of the
Stomper. To get long and trouble-free service from this power tool, periodic maintenance of the engine
and machine is essential.
The Stomper is shipped completely assembled and only requires filling engine with diesel fuel and a brief
check of lubricant levels in preparation for operation. You should first study these instructions.
