11) Grasp the operator handle with firm grip;ping.
When starting the electric motor, apply a down force
directly to the operator handle to help reduce the
amount of machine weight against the work surface.
Rotate the starter control grip with the right hand to
start the electric motor. Reduce the amount of applied
down force on the operator handle as the electric
motor attains its operational speed. The electric motor
will require additional time to help compensate for the
additional starting amperage required.
AS SOON AS THE ELECTRIC MOTOR HAS STARTED,
THE OPERATOR MUST BE IN A POSITION TO
ASSUME DIRECT AND FULL CONTROL OF THE
FLOOR GRINDER. FAILURE TO ASSUME DIRECT
AND FULL CONTROL CAN RESULT IN PROPERTY
DAMAGE AND/OR PERSONAL INJURY.
12) The Floor Grinder is stopped by rotating or
releasing the starter control grip with the right hand to
the oFF position. When not in use, turn the oN/oFF
master switch to the oFF position.
OPERATING THE FLOOR GRINDER ON THE JOB
SITE
Application: SG87SH SURFACE SHARK
THE GRINDING PROCESS PRODUCES EXCESSIVE
NOISE, VIBRATION AND FLYING DEBRIS. ALL
OPERATORS AND WORK PERSONNEL IN THE
VICINITY OF THE FLOOR GRINDER MUST WEAR
APPROPRIATE SAFETY EYE WEAR AND HEARING
PROTECTION DEVICES. OTHER SAFETY APPAREL
AND/OR PROCEDURES, DEEMED NECESSARY
BY SUPERVISORY PERSONNEL MUST ALSO BE
WORN AND/OR PRACTICED BY ALL APPROPRIATE
PERSONNEL.
EXERCISE EXTREME CAUTION WHEN OPERATING
THE FLOOR GRINDER IN THE VICINITY OF DECK
INSERTS, PIPES, COLUMNS, OPENINGS, LARGE
CRACKS, UTILITY OUTLETS OR ANY OBJECT
PROTRUDING FROM THE SURFACE. CONTACT
WITH SUCH OBJECTS CAN LEAD TO LOSS OF
MACHINE CONTROL, RESULTING IN PROPERTY
DAMAGE AND/OR PERSONAL INJURY.
1) The Floor Grinder incorporates a single rotating
disc for mounting a wide variety of multi-accessory
attachments.
2) The single disc of the SG87Sh Floor Grinder rotates
in a clockwise direction as viewed by the operator. This
action produces a torque effect that, during operation,
is counteracted by both the wheels and operator.
Reaction to the torque effect will attempt to move the
Floor Grinder in a counterclockwise direction. Proper
operator position can reduce the amount of torque
effect experienced by the operator. Assume a position
that allow exercising reactive “body english” against
the torque effect created by the specific process. Keep
upper arms as close to the upper body as possible to
maximize mechanical leverage. An operator should
position his back as vertical as possible by bending the
legs as required. Positioning the left foot ahead of the
right foot at a comfortable distance will enhance proper
body position. Maintaining proper operating position
is one of the most IMPoRTANT and EFFECTIvE
procedures for controlling the torque effect. Improper
operating positions only aggravate the effects of the
torque effect upon the operator. FIGuRE 17 depicts
a proper operator position. FIGuRE 18 depicts an
improper operator position.
