SKYJACK is continuously improving and expanding product features on its equipment, therefore, specifications

and dimensions are subject to change without notice.

Aerial Platform and Mobile Elevating Work Platform Definition

A mobile device that has a positionable platform supported from ground level by a structure.

Purpose of Equipment

The SKYJACK SJIII DC Electric series 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. Work platform elevation and elevated driving

must only be done on a firm level surface.

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

Scope of this Manual

a. This manual applies to the KC version of the SJIII Series aerial platform models listed on Table 2.1.

- Equipment identified with “KC” meets the requirements for South Korea, i.e., Act 2008-75 and the

corresponding KS B ISO 16368:2004 Korean standard.

a. Operators are required to conform to national, state or territorial/provincial and local health and safety regulations

applicable to the operation of this aerial platform.

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.

WARNING

Risk of an electric shock - Do not remove an Anti-Static Strip from the aerial platform.

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.

Per ANSI A92.6-2006 8.10(7)

“The operator shall perform only that work for which he or she is qualified, in compliance with all applicable

safety related work practices intended to prevent electric shock covered by the Code of Federal Regulations

(CFR) 1910.333. The operator’s level of competence shall be established only by persons qualified to do so. Op-

erators shall maintain the appropriate minimum approach distance (MAD) from energized power lines and parts

covered by CFR 1910.333 (c).”

Unqualified persons must maintain a minimum approach distance of 10 feet from any energized power line up to

50 kV. Energized power lines over 50 kV require a greater minimum approach distance to be maintained. Refer to

CFR 1910.333.

As per CSA B354.2-01

“The operator shall maintain the minimum safe approach distance (MSAD) from energized conductors at all times

in accordance with the authority having jurisdiction.”

DO NOT OPERATE THE AERIAL PLATFORM DURING LIGHTNING OR STORMS.

DO NOT OPERATE THE AERIAL PLATFORM NEAR POWER LINES. MAINTAIN A MINIMUM SAFE AP-

PROACH DISTANCE (MSAD) FROM ENERGIZED POWER LINES.
