Section 1 - Scheduled Maintenance Operator’s Responsibility for Maintenance

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 SJIII Compact and Conventional series aerial platforms are designed to transport and raise person-

nel, 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 SJIII 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.

For non-standard components or systems, contact the SKYJACK Service Department at

Section 1 - Scheduled Maintenance Operator’s Responsibility for Maintenance

WARNING

Failure to comply with your required responsibilities in the use and operation of the aerial platform

could result in death or serious injury!

Operator Safety Reminders

A study conducted by St. Paul Travelers showed that most accidents are caused by the failure of the operator to

follow simple and fundamental safety rules and precautions.

You, as a careful operator, are the best insurance against an accident. Therefore, proper usage of this aerial platform

is mandatory. The following pages of this manual should be read and understood completely before operating the

aerial platform.

Common sense dictates the use of protective clothing when working on or near machinery. Use appropriate safety

devices to protect your eyes, ears, hands, feet and body.

Any modifications from the original design are strictly forbidden without written permission from SKYJACK Inc.

Electrocution Hazard

This aerial platform is not electrically insulated. Maintain a Minimum Safe Approach Distance (MSAD) from energized

power lines and parts as listed below. The operator must allow for the platform to sway, rock or sag. This aerial

platform does not provide protection from contact with or proximity to an electrically charged conductor.

DO NOT USE AERIAL PLATFORM AS A GROUND FOR WELDING.

DO NOT OPERATE AERIAL PLATFORM DURING LIGHTNING OR STORMS.

driving shall not be allowed.

Position the aerial platform

horizontally only with the

platform fully lowered. After

ensuring that all 4 wheels or

outriggers (if equipped) have

contact with level firm surface,

the aerial platform can be el-

evated. After elevation, the

drive function must not be ac-

tivated.

• Elevated driving must only

be done on a firm level sur-

face.

• DO NOT ascend or descend

a grade when elevated. When

fully lowered, ascending or

descending, only grades up
