VISUAL
INSPECTION
This aerial lift is designed to provide years of reliable
service with minimum maintenance. A routine
preventive maintenance program will assure
extended aerial lift service. The operator is
responsible for detecting maintenance problems
during the daily visual inspection, reporting the need
for adjustments or repairs, verifying that maintenance
is performed at the suggested intervals, and
determining if the aerial lift is in a good, safe operating
condition. The importance of accurate maintenance
records cannot be over emphasized. In order to judge
the condition of the aerial lift, the operator needs to
be familiar with the maintenance records of the aerial
lift. Refer to the “Maintenance Checklist” in Service
Procedures Section of the Service Manual for the
suggested interval inspection information. The actual
repair or adjustment must be done by a qualified
aerial lift mechanic.
Every day the equipment must be thoroughly visually
inspected to detect problems before they become
serious. During this inspection the operator shall look
for anything out of the ordinary. Particular attention
must be paid to the following items. The Daily Visual
Inspection Checklist included in this section must be
followed.
BOLTS
- Critical fasteners are identified on the
“Critical Fasteners” drawing in this section. All major
sections of the
Versalift
are bolted together and it is
vital that these bolts remain tight. Visually inspect all
the bolts for signs of relative movement. Pay
particular attention to the load supporting bolts
(rotation bearing bolts, pedestal/subframe mounting
bolts, platform rotator bolts). Critical bolts are
Torque-Seal marked to provide a quick means of
detecting any turning. Do not use the lift if the
Torque-Seal mark between the bolt head and
mounting surface, are not in alignment. Refer to the
Maintenance and Inspection Schedule in Service
Procedures Section of the Service Manual for
recommended torque procedures and torque chart
specifications. Refer to Figure 6.1 and 6.2 for
Torque-Seal mark conditions.

WELDS
- Refer to the “Critical Welds” drawing in
this section. All the welds should be inspected for
signs of fatigue. Hairline cracks in a weld are a strong
indication of weld fatigue. Some critical welds that
warrant special attention are where the turret wings
are welded to the base plate, the cylinder mounts
are welded to the boom, the cylinder mounts are
welded to the turret, the knuckle welds on the booms,
and the welds on the platform mounting shaft.
HYDRAULIC LINES
- Hydraulic lines should be
inspected for loose connections and frayed jackets.
Carefully examine the hoses especially that portion
of the hose subject to flexing and particularly the
hoses at the platform.
OIL LEAKS
- Oil leaking onto the truck floor or on
the ground is a sign of an impending problem. A
hydraulic leak will create a slippery surface which is
potentially hazardous. When a hydraulic leak is
encountered it must be repaired by the proper service
personnel and the unit must be cleaned of excess
hydraulic oil. If a hydraulic leak is not repaired the oil
in the reservoir will be depleted and pump damage
may occur.
ELECTRICAL SYSTEM
- Inspect electrical system
for damaged components. Check for bare electrical
wires and remove any trash or debris from around
elctrical components. Repair all damaged wires and
secure any loose electrical components or wires.
VEHICLE TIRES
- Check tires for the correct inflation
and for damage. Low pressure or damaged tires
are unsafe while driving the vehicle or operating the
lift.
LOOSE OBJECTS
- Inspect the booms for loose
objects (tools, spare parts, etc.) that might fall when
the booms are elevated.
HYDRAULIC OIL LEVEL
- The hydraulic fluid level
can be easily checked by monitoring the oil level
through the sight gauges. Add hydraulic oil if
necessary. Refer to “Hydraulic Oil Recommendations”
in Service Procedures Section of the Service Manual
for oil recommendations. It is important to maintain
