MAINTENANCE
When working with electrical or electronic controls,
make sure that the power source has been tagged (
A
)
and locked out (
B
) according to OSHA regulations*
and approved local electrical codes (see Figure 25).
When maintenance is to be performed on the dock
leveler, place the maintenance props (
C
) in their
service/down position with hardware (
D
) tightened
by wrench. Ensure the storage prop (
E
) is locked out
with the prop pin and clip (
F
). See Figures 26 and
27. The lip may fold down if the platform has rested
on the maintenance props.
Only the person servicing the equipment should have
the capability to remove the lockout devices. The tag
out devices* must inform that repairs are in process
and clearly state who is responsible for the lockout
condition.
It is recommended and good safety practice to use
an additional means to support the dock platform
and lip anytime when physically working in front of
or under the dock leveler. This additional means
may include, but is not limited to a boom truck, fork
truck, stabilizing bar or equivalent.
* Refer to OSHA regulations 1910.146. Confined Space and 1910.147. Lockout/Tagout
Always post safety warnings and barricade the
work area at dock level and ground level to prevent
unauthorized use of the unit before maintenance is
complete.
A hard hat or other applicable head protection
should always be worn when working under or
around a dock leveler.
Always stand clear of platform lip when working in
front of the dock leveler.
