of the rear swing area before conducting turning maneuvers.
C Exercise particular care at cross
aisles, doorways, and other locations where pedestrians may step
4 EN
- 2
into the path of travel of the powered floor scrubber.
Do not permit passengers to ride on
powered floor scrubbers unless a safe
place to ride has been provided by the
manufacturer.
A powered floor scrubber is attended
when the operator is less than 25 ft.
(7.6 m) from the unit, which remains in
his view.
A powered floor scrubber is unattended when the operator is more than 25
ft. (7.6 m) from the unit, which remains
in his view, or whenever the operator
leaves the unit and it is not in his view.
Before leaving the operator’s position:
A bring the unit to a complete stop;
B place the directional controls in
neutral;
C apply the parking brake;
D stop the engine or turn off the con-
trols;
E if the unit must be on an incline,
block the wheels.
Maintain a safe distance from the edge
of ramps, platforms, and other similar
working surfaces.
When powered floor scrubbers are
driven on and off highway trucks or
trailers, the brakes on the highway
trucks or trailers shall be applied and
wheel chocks or other positive mechanical means shall be used to prevent unintentional movement of
highway trucks and trailers.
Whenever powered floor scrubbers
are driven on and off semitrailers that
are not coupled to a tractor, supports
may be needed to prevent upending or
corner dipping.
Care shall be taken not to contact overhead installations such as lights, wiring, pipes, sprinkler systems, etc.
Report all accidents involving personnel, building structures, and equipment
to the supervisor or as directed.
Do not add to, or modify the unit.
Do not block access to fire aisles, stairways or fire equipment.
Travelling
Observe all traffic regulations including
authorized plant speed limits. Under
normal traffic conditions, keep to the
right. Maintain a safe distance, based
on speed of travel, from the unit ahead;
and keep the unit under control at all
times.
Yield the right of way to pedestrians
and emergency vehicles such as ambulances and fire trucks.
Do not pass another truck travelling in
the same direction at intersections,
blind spots, or at other dangerous locations.
Slow down and sound the audible
warning device(s) at cross aisles and
other locations where vision is obstructed.
Cross railroad tracks at an angle wherever possible. Do not park closer than
6 ft (1800 mm) to the nearest rail of a
railroad track.
Ascend or descend grades slowly, and
with caution. Avoid turning, if possible,
