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. 
 

 

 
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. 

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
