A powered floor scrubber is unattend-
ed 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 me-
chanical means shall be used to pre-
vent unintentional movement of high-
way 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 over-
head installations such as lights, wir-
ing, pipes, sprinkler systems, etc.
Report all accidents involving person-
nel, 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, stair-
ways 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 am-
bulances and fire trucks.
Do not pass another truck travelling in
the same direction at intersections,
blind spots, or at other dangerous loca-
tions.
Slow down and sound the audible
warning device(s) at cross aisles and
other locations where vision is ob-
structed.
Cross railroad tracks at an angle wher-
ever 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,
and use extreme caution on grades,
ramps, or inclines; normally travel
straight up and down.
Keep a clear view of the path of travel
and observe for other traffic, person-
nel, and safe clearances.
Under all travel conditions, operate the
unit at a speed that will permit it to be
brought to a stop in a safe manner.
Make starts, stops, turns, or direction
reversals in a smooth manner so as
not to shift load and/or overturn the
powered floor scrubber.
Do not indulge in stunt driving or horse-
play.
Slow down for wet and slippery floors.
Before driving over a dockboard or
bridge plate, be sure that it is properly
secured. Drive carefully and slowly
across the dockboard or bridge plate,
and never exceed its rated capacity.
Do not drive powered floor scrubbers
onto any elevator unless specifically
authorized to do so. Approach eleva-
tors slowly, and then enter squarely af-
ter the elevator car is properly leveled.
Once on the elevator, neutralize the
controls, shut off power, and set
brakes. It is advisable that all other per-
sonnel leave the elevator before the
powered floor scrubber is allowed to
enter or leave.
When negotiating turns, reduce speed
to a safe level consistent with the oper-
ating environment. Make the turns
smoothly. Except when maneuvering
at a very low speed, turn the steering
control at a moderate, even rate.
The operation of a powered floor
scrubber requires special safety con-
siderations, as follows:
A A powered floor scrubber may tip
over if an operator fails to slow down to
a safe speed before making turns. Indi-
cations that a truck is being driven at
an excessive speed during turning ma-
neuvers include:
1 tire skidding;
2 unit side sway;
3 wheel lift; and
4 the need to grip the steering wheel
tightly to keep from sliding out of the
seat.
B The likelihood of lateral tipover is in-
creased under any of the following
conditions, or combinations of them:
1 travelling on an uneven surface;
2 travelling at excessive speed.
C Tipping forward can occur and its like-
liehood is increased under the following
conditions, or combination of them:
1 The operator should stay with the
powered floor scrubber if it falls off
a loading dock or ramp. The opera-

tor should hold on firmly and lean
away from the point of ipact.
2 Where the enviroment presents a
severe hazard, or there are other
unusual operating conditions, the
user may need to establish different
and/or additional safety precautions
and special operating instructions
appropriate for the conditions.

Operator care of the unit

At the beginning of each shift and be-
fore operating the powered floor scrub-
ber, check its condition, giving special
attention to the following:
A condition of tires
B if pneumatic tires, check inflation
pressures
C warning and safety devices
D lights
E battery
F controls
G lift and tilt systems
H chains and cables
I
limit switches
J brakes
K steering mechanism
L additional items or special equip-
ment as specified by the user and/
or manufacturer
If the unit is found to be in need of re-
pair or in any way unsafe, or contrib-
utes to an unsafe condition, the matter
shall be reported immediately to the
user's designated authority, and the
unit shall not be operated until it has
been restored to safe operating condi-
tion.
If during operation the unit becomes
unsafe in any way, the matter shall be
reported immediately to the user's des-
ignated authority, and the unit shall not
be operated until it has been restored
to safe operating condition.
Do not make repairs or adjustments
unless specifically authorized to do so.
Do not use open flames when check-
ing electrolyte level in storage batter-
ies.
MAINTENANCE AND
REBUILD PRACTICES
Operation of the unit may be hazard-
ous if maintenance is neglected or re-
pairs, rebuilds, or adjustments are not
performed in accordance with the man-
ufacturer's design criteria. Therefore,
maintenance facilities (on or off prem-
ises), trained personnel, and detailed
procedures shall be provided.
Parts manuals and maintenance man-
uals may be obtained by the powered
floor scrubber manufacturer.
