the proper hydraulic oil level because a full reservoir
will minimize the operating temperature and, in the
event of a hydraulic line leak, a full reservoir gives the
operator more time to lower the platform. Caution: do
not overfill the oil reservoir.
CONTROLS - Operate all the lift controls through
the full range of motion to verify the controls function
properly.
LEVELING SYSTEM - The leveling system in the
Versalift is subject to wear and has a limited life.
Failure of the leveling system may cause the platform
to tip rapidly. The system is comprised of chains,
sprockets, insulator rods, and tensioners. Refer to
Parts & Assemblies Section of the Service Manual
for these components. For inspection, the access
covers must be removed from the lower and upper
booms. The leveling system must be inspected every
90 days for proper tension, fatigue, excessive wear,
and for rods pulling out of sockets. If these conditions
exist they must be repaired by qualified personnel
before operation.
An application of lubricant annually will help extend
the chain life. A penetrating lubricant designed for
chain use, such as Lubriplate "Chain and Cable
Spray," should be used.
DECALS - Identification, operational, and
instructional decals are installed at numerous
locations on the Versalift. These decals must be
replaced if they become lost, damaged, or illegible.
Refer to the "Decal Placement" illustration in this
section for a complete decal listing and the locations
of all the decals.
FIBERGLASS BOOM - Inspect the fiberglass upper
boom and the lower boom inserts for an accumulation
of dirt that can impair the insulating value of the
fiberglass. The fiberglass outer surface of the booms
should be cleaned daily with a lint free cloth. If the
fiberglass sections require a more thorough cleaning,
Refer to Service Procedure Section, "Care of
Fiberglass Booms" of the Service and Installation
Manual. Check for any structural damage in the
fiberglass such as cracks or gouges. If these
conditions exist, they must be reapired by qualified
personnel.
PLATFORM - Inspect the platform for cracks in the
mounting ribs, floor, and flange around the top. If
these conditions exist they must be repaired by
qualified personnel before operation.
ROPE - Make a thorough check of the winch rope for
abrasive wear, pulled strands, cuts, and other
VERSALIFT VO-452/455/460-MHI
defects. The rope should be clean and dry. The rope
coils should spool evenly on the winch reel. Do not
use a rope that has been subjected to shock loads.
Replace the winch rope at the first sign of damage or
deterioration. Use only non-conductive rope of the
size and type specified.
WINCH - Verify that the rope coils are spooling
evenly. Check for hydraulic leaks as well as leaks
from the winch drive gearbox.
SLOPE INDICATORS - The indicators are installed
at several locations on the Versalift chassis. Check
that indicators are in place and not damaged. Refer to
slope indicator installation in "Parts and Assemblies"
Section in the Service Manual.
SAFETY DEVICES – Check visual and audible safety
devices for proper operation.
COVERS – Inspect all covers to make sure they are
in place, secure and in good condition.
