Maintenance
Every person who maintains, inspects, tests or repairs the
aerial platform must be qualified to do so. Maintenance
functions must be performed by maintenance personnel
who are qualified to work on the aerial platform.
Caution
A
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 the battery cables and any
microprocessors and engine control modules before
welding on the machine.
If it becomes necessary to weld aerial platform com-
ponents as a method of repair, take all precautions to
prevent damage to electronic circuitry and devices on
the machine. This includes, but may not be limited to,
disconnecting battery cables and electronic devices.
Do not modify this aerial platform without prior writ-
ten consent of the Snorkel Engineering Department.
Modification may void the warranty, adversely affect
stability or affect the operational characteristics of the
aerial platform.
Maintenance Schedules
Snorkel has established a preventative maintenance
schedule to detect any defective, damaged or improperly
secured parts and provide information regarding lubrica-
tion and other minor maintenance items.
This schedule includes the following:
Daily Prestart Inspection
y
Frequent Inspection and Maintenance – Every 30
y
Days or 50 Hours
Frequent Inspection and Maintenance – Every 180
y
Days or 250 Hours
Annual Maintenance – Every 500 Hours
y
The Daily Prestart Inspection must be performed by a
trained operation. All other maintenance and inspection
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 preventative inspection and maintenance checklists
for your use in performing these inspections.

Warning
A
The potential for accident increases when operating
an aerial platform that is damaged or malfunction-
ing. 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
service.
General Information
The parts drawings located in the Repair Parts section
are designed for use as a guide for proper disassembly
of the machine and components, as well as, for parts
replacement.
Danger
A
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,
complete the procedural step in sequence. Do not par-
tially 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.
y
Never attempt to lift heavy objects without the aid
y
of a mechanical device.
Do not allow heavy object to rest in an unstable
y
condition.
Always make sure the work platform is in the
y
stowed position, blocked or the weight removed
by a suitable lifting device before removing any
components from the machine.
When raising a portion of the machine, be sure
y
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-
y
ers, electrical wiring, hydraulic lines, etc., have
been removed or that other parts are not interfering.
