SKYJACK is continuously improving and expanding product features on its equipment, therefore, specifications
and dimensions are subject to change without notice.
Aerial Platform Definition:
A mobile device that has an adjustable position platform supported from ground level by a structure.
Purpose of Equipment:
The SKYJACK Rough Terrain’s mid and full size aerial platforms are designed to transport and raise personnel, tools
and materials to overhead work areas.
Use of Equipment:
The aerial platform is a highly maneuverable, mobile work station. Lifting and driving must be on a flat, level,
compacted surface. It can be driven over uneven terrain only when the platform is fully lowered.
Manuals:
Operating:
The operating manual is considered a fundamental part of the aerial platform. It is a very important way to
communicate necessary safety information to users and operators. A complete and legible copy of this manual
must be kept in the provided weather-resistant storage compartment on the aerial platform at all times.
Service & Maintenance
The purpose of this is to provide the customer with the servicing and maintenance procedures essential for
the promotion of proper machine operation for its intended purpose.
All information in this manual should be read and understood before any attempt is made to service the machine.
The updated copy of the manuals are found on the company’s website: www.skyjack.com.
Operator:
The operator must read and completely understand both this operating manual and the safety panel label located
on the platform and all other warnings in this manual and on the aerial platform. Compare the labels on the aerial
platform with the labels found within this manual. If any labels are damaged or missing, replace them immediately.
Service Policy and Warranty:
SKYJACK warrants each new SJRT series work platform to be free of defective parts and workmanship for the first
24 months. Any defective part will be replaced or repaired by your local SKYJACK dealer at no charge for parts or
labor. Contact the SKYJACK Service Department for warranty statement extensions or exclusions.
Optional Accessories:
The SKYJACK aerial platform is designed to accept a variety of optional accessories. These are listed under “Standard
and Optional Features” in Table 2.1 of the operating manual. Operating instructions for these options (if equipped)
are located in section 2 of the operating manual.
