ASSEMBLY INSTRUCTIONS/OPERATIONS
3)Using the funnel, fill the fuel tank with fresh, clean fuel according to the specifications outlined in the material supplied by the engine manufacturer. Do not overfill the tank or spill any fuel. If the fuel tank incorporates a screen mesh to prevent debris from falling into the tank, do not remove to increase the fill rate. Replace the filler cap. Wipe away any excess spilled fuel.
DANGER
MANY FUELS ARE EXTREMELY FLAMMABLE. DO NOT SMOKE NEAR THE FUEL TANK. DO NOT FILL THE FUEL TANK WITH THE ENGINE RUNNING OR IF IT IS HOT. ALLOW AMPLE TIME BETWEEN EACH REFUELING FOR THE ENGINE TO COOL.
Operation
THEORY OF OPERATION
Application: All Models.
The 8FP Series Floor Planers operate on the principle of various flail configurations being operated at high rotational speeds to make direct contact with a work surface. A series of flails are spaced and aligned on shafts that span a specified width and rotate on a drum that can be raised or lowered at the discretion of the operator. The specific flail configuration and impact rate directly affect the rate of material removal from the work surface, the resulting surface profile and texture.
The planing process is directly controlled by these conditions:
1)The use of a suitable mechanism (flail) of sufficient strength and hardness to impact the work surface and remove material while delivering an acceptable service life.
2)Sufficient static weight supporting the flails which allow them to effectively penetrate the work surface and remove material.
3)Adequate horsepower capable of propelling the rotating flails against the work surface to deliver acceptable productivity rates.
Since no two materials are exactly alike, no two work surface materials can be penetrated and removed by the exact same method. The nature of the planing process, along with operator experience, skill and common sense, would suggest that efficient and productive material removal is a matter of trial and error. Combinations of flail type, condition, configuration, spacing along the width of the flail drum and feed rate are direct factors that will determine the overall success of the job application.
FLAIL DESIGN AND APPLICATION.
While individual flail design and configuration may vary, basic operational characteristics are identical: impact a work surface material and remove a percentage of the material. This common operational characteristic has led to the development of two basic flail configurations:
1)High carbon, heat treated, alloy steel designed for direct contact and removal of the surface material. The high carbon content of the flail material also helps to improve service life
2)High carbon, heat treated, alloy steel with tungsten carbide inserts brazed into the flail body. The tungsten carbide inserts are intended to directly contact the work surface and remove material. The inserts effectively resist wear and usually deliver a substantially longer service life than the plain, heat treated steel types. The flail body is designed to serve as a matrix or support for the tungsten carbide inserts, hence the requirement for heat treatment. The heat treatment process also aids the flail body in resisting wear.
Several factors directly affect the selection of a flail design for a specific job application:
1)The type and amount of material to be removed from the work surface. Materials of higher yield and tensile strengths along with the actual volume of material to be removed will generally be the first factors under consideration.
2)Purchase costs versus service life. The original purchase cost of plain, heat treated steel flails must be compared against the substantially higher costs of tungsten carbide insert flails. In turn, these costs must be compared to anticipated service life. All flails, whether of high speed steel or tungsten carbide insert design, will eventually wear to the point of requiring replacement. The amount of unproductive time spent to replace worn flails on a job can be substantially greater than the actual replacement cost of many flails. It then becomes a balance between purchase cost, productivity, service life and labor cost.
3)Surface finish and texture. The finest grained surface finish available from the planing process is comparable to a "swept or broomed" like finish. FIGURE 1. If a smooth, flat finish is desired, the planing process must be followed with a grinding or polishing type process. Many job requirements may call for large amounts of material to be removed, but followed with additional specifications requiring a finer surface finish or texture. Many times these jobs dictate
