SP684 SuRFACE ShARK SuRFACE PLANER PAGE 5
The concept of portable, low horsepower type surface planing equipment has been successfully
utilized for many years as a practical solution to many types of surface preparation job requirements.
The basic concept is proven and well accepted within the associated marketplaces as an alternative
method to manual labor and other types of machines and methods. Use of a Surface Planer requires
strenuous work activity. This type of work activity can be considered to be greater in magnitude than
that experienced with the use of many other types of both light construction and lawn and garden
related equipment. This type of work activity should only be attempted by operators of adequate
physical size and stature, mental awareness and physical strength and condition. Each operator
is required to supply a reaction type force that counteracts/balances and/or resists the forces
generated during the surface planing process. The body parts most noticeably affected during the
planing process are the arms, hands, wrists, shoulders, lower back and legs. The planing process
can also produce excessive stress/strain directly to the back muscles, spinal vertebrae and many
other body parts. Back related pain can be a side effect of the planing process. An operator with a
chronic back related problem or a history of back and/or other medically related problems should
not attempt to utilize the Surface Planer. Use of the Surface Planer may only aggravate this and
any other medically related problem. The forces generated and/or encountered correspond to the
natural laws of physics and are inherent to the planing process. They can not be changed or totally
eliminated with portable hand held and operated, surface planing equipment of this design. Proper
operating positions and techniques, as outlined in this manual, can be successfully utilized to
minimize the effects of the reaction forces upon the human body. Because of the diverse type of
prevailing job applications, job site conditions, operator experience levels and operator physical
characteristics, no warranty, guarantee, representation and/or liability is made by the manufacturer
as to the absolute correctness or sufficiency of any operational procedure, operational position and/
or technique. There is no absolute guarantee that an operator of any given experience level, physical
size and/or physical condition will be immune to the possibility of and/or probable physical side
effects of the normal surface planing process. The normal planing process includes the flails striking
a wide variety of surface materials and compositions and the resulting reaction forces created. Each
potential operator of the Surface Planer must be made aware of and assume the operational and
physical liability described and/or associated with the planing process when utilizing the Surface
Planer. Each potential operator not willing to assume the operational and physical liability described
and/or associated with the planing process should not operate the Surface Planer. Proper levels
of operator experience, skill and common sense are essential for maximizing the safe and efficient
operation of the Surface Planer.
