Safe Maintenance Practices
The following instructions have been prepared from current industry and government safety standards applicable to
industrial truck operation and maintenance. These recommended procedures specify conditions, methods, and accepted
practices that aid in the safe maintenance of industrial trucks. They are listed here for the reference and safety of all
workers during maintenance operations. Carefully read and understand these in-
1.
Powered
industrial
trucks
can
become
hazardous
if
maintenance
is
neglected.
Therefore,
suitable
maintenance
facilities,
trained personnel, and procedures must be
provided.
2.
Maintenance and inspection of all powered
industrial trucks shall be done in conformance
with the manufacturer’s recommendations.
3.
A scheduled planned maintenance, lubrication,
and inspection program shall be followed.
4.
Only trained and authorized personnel should be
permitted to maintain, repair, adjust, and inspect
industrial trucks, and in accordance with the
manufacturer’s specifications.
5.
Properly ventilate work area, vent exhaust
fumes, and keep shop clean and floor dry.
6.
Avoid fire hazards and have fire protection
equipment in the work area. Do not use an open
flame to check for level, or leakage of fuel,
electrolyte, or coolant. Do not use open pans of
fuel or flammable cleaning fluids for cleaning
parts.
7.
Before Starting Work On Truck:
a)
Raise
drive
wheels
off
of
floor
or
disconnect power source and use blocks
or other positive truck-positioning devices.
b)
Put blocks under the upright rails and
carriage, innermast(s), or chassis before
working on them.
c)
Disconnect battery before working on the
electrical system.
8.
Operation of the truck to check performance
must be conducted in an authorized, safe, clear
area.
9.
Before Starting To Drive Truck:
a)
Be in operating position.
b)
Disengage
clutch
on
manual
transmissions, or apply brake on trucks
with powershift transmission.
c)
Put directional control in neutral.
d)
Start engine.
e)
Check functioning of lift and tilt systems,
directional and speed controls, steering,
brakes, warning devices, and any load
handling attachments.
10.
Before Leaving Truck:
a)
Stop truck.
b)
Fully lower the load engaging means:
upright, carriage, forks, or attachments.
c)
Put directional control in neutral.
d)
Apply the parking brake.
e)
Stop the engine.
f)
Turn off the control of ignition circuit.
g)
Put blocks at the wheels, if truck is on an
incline.
h)
Remove
the
ignition
key
(OSHA
regulation).
11.
Brakes,
steering
mechanisms,
control
mechanisms, warning devices, lights, governors,
lift overload devices, guards and safety devices,
lift and tilt mechanisms, articulating axle stops,
and frame members must be carefully and
regularly inspected and maintained in a safe
operating condition.
12.
Special
trucks
or
devices
designed
and
approved for hazardous-area operation must
receive
special
attention
to
ensure
that
maintenance preserves the original, approved
safe operating features.
13.
Fuel systems must be checked for leaks and
condition of parts. Extra special consideration
must be given in the case of a leak in the fuel
system. Action must be taken to prevent the use
of the truck until the leak has been corrected.
14.
All
hydraulic
systems
must
be
regularly
inspected and maintained in conformance with
good practice. Tilt and lift cylinders, valves, and
other similar parts must be checked to assure
that "drift" or leakage has not developed to the
extent that it would create a hazard.
15.
When working on hydraulic system, be sure the
engine is turned off, upright is in its fully-lowered
position, and hydraulic pressure relieved in
hoses and tubing.
16.
Batteries, motors, controllers, limit switches,
protective devices, electrical conductors and
connections must be inspected and maintained
in conformance with good practice. Special
attention must be paid to the condition of
electrical insulation.
