ly to keep from sliding out of the seat.
B The likelihood of lateral tipover is in-
creased under any of the following condi-
tions, or combinations of them:
1 traveling on an uneven surface;
2 traveling at excessive speed.
C Tipping forward can occur and its likeli-
hood is increased under the following con-
ditions, or combination of them:
1 The operator should stay with the pow-
ered floor scrubber if it falls off a loading
dock or ramp. The operator should hold
on firmly and lean away from the point of
impact.
2 Where the enviroment presents a se-
vere hazard, or there are other unusual
operating conditions, the user may need
to establish different and/or additional
safety precautions and special operat-
ing instructions appropriate for the con-
ditions.
At the beginning of each shift and before
operating the powered floor scrubber,
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
Ebattery
F controls
G lift and tilt systems
H chains and cables
I limit switches
J brakes
K steering mechanism
L additional items or special equipment as
specified by the user and/or manufac-
turer
If the unit is found to be in need of repair or
in any way unsafe, or contributes to an un-
safe condition, the matter shall be reported
immediately to the user’s designated au-
thority, and the unit shall not be operated
until it has been restored to safe operating
condition.
If during operation the unit becomes unsafe
in any way, the matter shall be reported im-
mediately to the user’s designated authori-
ty, and the unit shall not be operated until it
has been restored to safe operating condi-
tion.
Do not make repairs or adjustments unless
specifically authorized to do so.
Do not use open flames when checking
electrolyte level in storage batteries.
Operation of the unit may be hazardous if
maintenance is neglected or repairs, re-
builds, or adjustments are not performed in
accordance with the manufacturer’s design
criteria. Therefore, maintenance facilities
(on or off premises), trained personnel, and
detailed procedures shall be provided.
Parts manuals and maintenance manuals
may be obtained by the powered floor
scrubber manufacturer.
In unusual cases not covered by the man-
uals referred above, consult the powered
floor scrubber manufacturer.
Maintenance and inspection of the unit
shall be performed in conformance with the
following practices:
A a schedules planned maintenance, lu-
brication, and inspection system shall
be followed; consult the manufacturer’s
recommendations.
B only tranined and authorized personnel
shall be permitted to maintain, repair,
adjust, and inspect the unit, and in ac-
cordance with manufacturer’s specifica-
tions.
When lifting powered floor scrubbers for re-
pair or inspection, the units shall be lifted in
a safe, secure, stable manner. Removal of
components such as counterweights or up-
rights will change the center of gravity and
may create an unstable condition.
Before starting inspection and repair of
powered floor scrubber:
A raise drive wheels free of floor and dis-
connect battery and use chocks or other
positive truck-positioning devices;
B block chassis before working on them;
C disconnect battery before working in the
electrical system;
D the charger connector shall be plugged
only into the battery connector and nev-
er into the unit connector.
Operation of the powered floor scrubber to
check the performance shall be conducted
in an authorized area where safe clearance
exists.
A Before starting to operate the unit:
1 be in operating position;
2 apply brake;
3 place directional controls in neutral;
4 turn switch to ON position;
5 check functioning of lift and tilt systems,
steering, warning devices, and brakes.
B Before leaving the unit:
1stop unit;
2 place directional control in neutral;
3 apply the parking brake;
4 stop the engine or turn off the power;
5 turn off the control circuit;
6 if the unit must be left on an incline,
block the wheels.
Avoid fire hazards and have fire protection
equipment present in the work area. Do not
use an open flame to check the level of any
fluid, especially battery electrolyte. Do not
use open pans of fuel or flammable clean-
ing fluids for cleaning parts.
Properly ventilate work area, vent exhaust
fumes, and keep shop clean and dry.
Brakes, steering mechanisms, control
mechanisms, warning devices, lights, gov-
ernors, guards and safety devices, articu-
lating axle stops, and frame members shall
be carefully and regularly inspected and
maintained in safe operating condition.
Any unit not in safe operating condition
shall be removed from service.
Repairs to the electrical system of battery
powered floor scrubbers shall be performed
only after the battery has been disconnect-
ed.
Operating Temperature. When the tem-
perature of any part of any powered floor
scrubber is found to be in excess of its nor-
mal operating temperature and creates a
hazardous condition, the vehicle shall be
removed from service and shall not be re-
turned to service until the cause for such
overheating has been eliminated.
Fire Prevention.
The unit shall be kept in a
clean condition and reasonably free of lint,
excess oil, and grease. Noncombustible
agents are preferred for cleaning the unit.
Flammable liquids [those having flash
points at or above 100°F (37,8°C)] are not
allowed. Precautions regarding toxicity,
ventilation, and fire hazard shall be appro-
priate for the agent or solvent used.
Nameplate Visibility. The unit type desig-
nations as shown on the nameplate and the
type markers shall not be covered over with
paint so that their identification information
is obscured.
Changing and Charging Storage Batter-
ies.
This section shall apply to batteries used on
electric trucks. The two types of batteries
commonly are lead and nickel-iron. They
contain corrosive chemical solutions, either
acid or alkali, and, therefore, present a
chemical hazard. While being charged,
they give off hydrogen and oxygen, which,
in certain concentrations, are explosive.
Battery-charging installations shall be locat-
ed in areas designated for that purpose;
such areas shall be kept free of extraneous
combustible materials. Facilities shall be
provided for the following:
A Flushing spilled electrolyte;
B Fire protection;
C Protecting charging apparatus from
damage by trucks, and
D Adequate ventilation for dispersal of
fumes from gasing batteries.
Where on-board chargers are used, charg-
ing shall be accomplished at locations des-
ignated for that prupose, taking into
account the electrical requirements of the
charger and facilities for fire protection.
Exception: Flushing facilities shall not be
required if charging is accomplished with-
out removing the battery from the vehicle.
Where handling acid concentrates greater
than 50 percent acid (above 1.400 specific
gravity) an eye-wash fountain shall be pro-
vided.
A conveyor, overhead hoist, or equivalent
material handling equipment shall be pro-
vided for handling batteries.
Chain hoists shall be equipped with load-
chain containers. Where a hand hoist is
used, uncovered batteries shall be covered
with a sheet of plywood or other noncon-
