S2646/S3246 Maintenance – 3
Maintenance
Every person who maintains, inspects, tests, or repairs
the aerial platform must be qualified to do so. Mainte-
nance functions must be performed by maintenance per-
sonnel who are qualified to work on the aerial platform.
A
Caution
Welding current can be very intense. Damage to
electronic components can result. Connect the
ground clamp as close as possible to the area be-
ing welded. Disconnect battery cables and any mi-
croprocessors and engine control modules before
welding on the machine.
If it becomes necessary to weld aerial platform compo-
nents as a method of repair, take all precautions to pre-
vent damage to electronic circuitry and devices on the
machine. This includes, but may not be limited to, dis-
connecting battery cables and electronic devices.
Do not modify this aerial platform without prior written
consent of the Snorkel Engineering Department. Modifi-
cation may void the warranty, adversely affect stability, or
affect the operational characteristics of the aerial plat-
form.
Maintenance Schedules
Snorkel has established a preventive maintenance sched-
ule to detect any defective, damaged or improperly se-
cured parts and provide information regarding lubrication
and other minor maintenance items.
This schedule includes the following:
• Daily Prestart Inspection
• Frequent Inspection and Maintenance
Every 90 Days or 150 Hours
• Annual Maintenance – Every 500 Hours
The Daily Prestart Inspection must be performed by a
trained operator. All other maintenance and inspections
must be performed by a trained service technician only.
Retain a copy of these forms for your records.
All placards and decals on the machine must be in place
and legible. Use the Placards and Decals parts page in
the Repair Parts section of this manual to check these
placards and decals.
Snorkel recommends that you make additional copies of
the Preventive Inspection Maintenance Checklist forms
for your use in performing these inspections.
A
Warning
The potential for an accident increases when oper-
ating an aerial platform that is damaged or mal-
functioning. Death or serious injury can result from
such accidents. Do not operate the aerial platform
if it is damaged or malfunctioning.
Repair all defects before returning the machine to ser-
vice.
General Information
The parts drawings located in the repair parts sections,
are designed for use as a guide for proper disassembly of
the machine and components as well as for parts re-
placement.
A
Danger
Hydraulic fluid escaping under pressure can have
enough force to inject fluid into the flesh. Serious
infection or reaction will result if medical treatment
is not given immediately. In case of injury by escap-
ing hydraulic fluid, seek medical attention at once.
Always refer to the hydraulic system installation draw-
ings and the electrical wiring diagram before removing or
disassembling associated parts.
When disassembling or reassembling components, com-
plete the procedural steps in sequence. Do not partially
disassemble or assemble one part, then start on another.
Always check your work to assure that nothing has been
overlooked.
Keep the following in mind when disassembling or as-
sembling the machine.
• Always be conscious of weight.
• Never attempt to lift heavy objects without the aid
of a mechanical device.
• Do not allow heavy objects to rest in an unstable
condition.
• Always make sure the work platform is in the
stowed position, blocked or the weight removed by
a suitable lifting device before removing any com-
ponents from the scissor stack.
• When raising a portion of the machine, be sure
that adequate blocking is properly positioned. Do
not depend solely on the lifting device to hold and
secure weight.
• If a part resists removal, check to see if all fasten
ers, electrical wiring, hydraulic lines, etc., have been
removed or that other parts are not interfering.
