MAINTENANCE
When working with electrical or electronic controls,
make sure that the power source has been locked
out and tagged according to OSHA regulations and
approved local electrical codes.
Post safety warnings and barricade work area, at dock
level and at ground level, to prevent unauthorized
use of the dock position.
A safe work place requires all lights and the horn to
be working properly. DO NOT use DOK-LOK vehicle
restraint if parts are broken or missing.
Maintenance may be required more frequently at
loading docks exposed to harsh environments
(extreme climates, corrosive chemicals, frequency
of usage, etc.). Consult Rite-Hite if these conditions
exist for accelerated maintenance requirements.
NOTE:
If a leveler is installed at the VBR DOK-LOK
vehicle restraint location, it may be necessary to
raise the leveler before performing maintenance
Raise the leveler, insert and secure the
SAFE-T-STRUT, and LOCKOUT/TAGOUT the
power source

Your local Rite-Hite representative provides a
Planned Maintenance Program (P.M.P.) which can
be fitted to your specific operation. Call your local
