OTHER IMPORTANT OPERATIONAL SAFETY WARNINGS
Never be under the DUAL-DOK
®
platform or lip
without:
• Engaging the support latch by pulling the
activation chain and pressing and holding
the Lift DOWN button until the platform
stops decending as shown in Figure 2,
• Pulling the selector valve activation chain
out to prevent scissors movement as
shown in Figure 4,
• If lip needs to be extended, follow procedures
on page 6, Figure 5,
• Locking out and tagging out the main
power source, as shown under Safety
Warnings on page 4.
Always barricade the DUAL-DOK
®
at ground
level and dock level from any form of traffic
when maintenance is required.
• Before loading/unloading operations begin,
secure the truck with wheel chocks or a
vehicle restraint and turn the outside light
selector switch to RED. See Figure 20. The
LED will change from GREEN position to the
RED. No controls will functions until the
outside light has been changed to RED.
Remove wheel chocks and/or restraint only
when loading or unloading is complete.
• Before starting installation or maintenance,
check and follow the safety procedures of the
facility where the DUAL-DOK
®
is being
installed.
• In Leveler Mode, the DUAL-DOK
®
should not
be raised or lowered to an operating position
with a load on the platform. When in Leveler
Mode, pushing the RAISE button will perform
a weight check. Operation will then continue.
In Lift or Auto-lip Modes, the platform may be
raised or lowered under a load.
• Always return the platform to dock height and
change to Leveler Mode when loading has
been completed. (A pulsing horn indicates
that the platform has been below dock height
for 15 minutes. Return lift to dock height or
cancel by pressing Lift UP or DOWN buttons.)
• DO NOT operate in any mode with anyone
under platform or in front of the lip.
• If a malfunction does occur, always call your
authorized RITE-HITE
®
service representative
immediately.
