TECH TIP
USB Flash Drive

The USB Flash Drive (part #167847) that is available from our parts department contains the current Service and Parts manuals. This flash drive is an easy way for service personnel to access the manuals without internet access. It is perfect for technicians in the field with a laptop but no internet connection. It also allows the technician to access the correct manual for the serial number of the unit they are working on.

The flash drive is designed to be updated manually every 30 days. A new update is available after the 15th of each month. You will need a computer with internet access to load the update. To update the drive, open the Skyjack drive and look at the menu. Double-click on UpdateUSB and a menu containing AutoUpdateUSB will appear. Double-click on that and a dialog box will open asking Would you like to update? Y/N. Type in "Y" and hit Enter and it will start the update. The update contains any additions and changes made to the manual since the last update. Be patient, as some updates are long and take time to complete. Once completed, it will ask you to press enter to exit. USB

Recently there was a technical glitch with the update program, but there is a fix. Use this link www.skyjack.com/usb-fix or go to our website www.skyjack.com and look for the banners (see below) throughout the website, click on the banner and follow the instructions.

Any new USB Flash Drive purchased after October 25th, 2018 will have the fix installed.

On-Board Diagnostic Display

The SJ30 AJE/ARJE and SJ6832 RTE models use a motor controller system for function operation

Skyjack Tech Tip
SJ30 ARJE

The electric powered SJ30 AJE/ARJE articulating booms and the SJ6832 RTE rough terrain scissor models use a motor controller system for function operation. The system features an on-board Hour Meter/Diagnostic Display. When the unit is powered up, there will be some general information shown on the display.

First, it flashes the software revision number of the display followed by the software revision of the motor controller. For example, you may see “EP019” then “EP026” when the key is turned on. These are not error codes and aren’t listed in any code tables. The display then shows the hours of use.

Note: If the batteries are low, a turtle icon will appear; this means the unit is in creep mode and in need of recharge.

If the system detects an error, a flashing red LED and a wrench symbol will appear on the display along with any error codes. Consult the code tables in the correct Service Manual for the Serial Number of the machine you are working on for information regarding the specific codes that are displayed.

On-board Diagonstic Display
For more information please consult the correct Service Manual for the Serial Number of the unit you are working on. These are available at www.skyjack.com in section 5.

MODULAR KEY SWITCHES

It's important to use the correct switch blocks and key operator parts
Skyjack Tech Tip
MODULAR KEY SWITCHES

It is important, when replacing any pieces of the modular key switches, to use the correct switch blocks and key operator parts and to install them in the correct position.

For example, the current production Skyjack boomlift models 40/45T, 61/66T, 46/63AJ, and 82/86T with the Deutz 2.9L engine use a modular style key switch at the base controls.

Figure A shows a sample arrangement of the switch blocks – highlighting some items to look for when replacing some parts. Note: not all models use this exact switch block arrangement, always reference the correct drawing in the manual for the serial number of the unit you are working on.

Figures A and B

1. Looking at the switch from the back, the NOEM switch block mounts to the left side of the switch frame.
2. The NCLB switch block mounts to the center position of the switch frame.
3. The NC switch block mounts on top of the NCLB switch block as in Figure B.
4. There is no switch block mounted to the right space on the switch frame.

Figure B shows the NC and NCLB switch blocks - correctly assembled.

***After replacing any switch or other electrical component, fully function test the machine, making sure each function operates properly from all the controls in the platform and base. Consult the correct Operator’s Manual for that machine’s serial number.

Always use the correct Service, Parts, and Operator’s Manuals for the serial number of the unit you are servicing.

As always, if you have a question regarding this tech tip or any Skyjack product, please contact Skyjack Product Support at 1-800-275-9522 or email service@skyjack.com.

MOTOR CONTROLLER UNITS: CONTACTOR DIODE

Skyjack electric scissor lifts and vertical mast units both use a Motor Controller to regulate the speed of functions.

Skyjack Tech Tip
Motor Controller

Skyjack electric scissor lifts (MC labeled units) and vertical mast units (SJ12 & SJ16) both use a Motor Controller to regulate the speed of functions. These Motor Controller equipped models use the same pump motor contactor as the models without a Motor Controller, but with one important difference: the Motor Controller units require a suppression, or flyback diode between the coil terminals on the contactor.

The diode is placed between the power wire (19A) and ground wire (02). This diode prevents the voltage created when the contactor coil collapses from feeding back and damaging the Motor Controller.

The diode is shown between the power (19A) and ground (02) wires at the contactor coil terminals. See Figure 1.

Figure 1

Original equipment diodes have a + and – sign molded into the diode body as shown. If you are using a replacement diode, Part #102921, make sure the silver stripe on the diode is facing wire 19A. The contactor replacement part number is #165865. It will arrive with a new diode installed, but always make sure the diode is installed on all Motor Controller units.

If you have any questions regarding this part or anything regarding your Skyjack product, please contact Skyjack Product Support at 1-800-275-9522 or email service@skyjack.com.

Manual Storage Box

All Skyjack mobile elevating work platforms are equipped with a manual storage box.

MANUAL STORAGE BOX ON AN SJ66 T

All Skyjack mobile elevating work platforms are equipped with a manual storage box. The weather resistant plastic box is located either on the platform or in the base control area. The manual storage box should always be in good condition – attached securely to the machine, no missing parts, and weather tight to keep the documents inside clean and dry. The box contains important documents for personnel who use the mobile elevating work platform - the ANSI Manual of Responsibilities and the Skyjack Operating Manual for that model and serial number. Current ANSI standards require both the ANSI Manual of Responsibilities and the Skyjack Operating Manual to be with the machine at all times. Some jurisdictions also require that a copy of the Certificate of Compliance to relevant ANSI and CSA standards be kept with the machine. All new Skyjack mobile elevating work platforms are shipped with these documents in the storage box.

As stated on its front cover, the ANSI Manual of Responsibilities is a compliance guide for dealers, owners, users, operators, lessors, lessees, and brokers. The manual in the storage box should be clean, complete, and legible. It must be the most current edition from ANSI, and copies are available from Skyjack's parts department and ANSI.

The Skyjack Operating Manual must be the correct manual for the model and serial number of the work platform on which it is placed. Reprints of the Skyjack Operating Manual are permitted but they must be complete, legible, and correct for the platform on which it is placed. Skyjack has the operating manuals in .pdf format and available for print on our website www.skyjack.com.

There is another manual that you may find in the storage box: the AEM Aerial Platform Safety Manual for Operating and Maintenance Personnel. This manual from the Association of Equipment Manufacturers is a generic safety manual for mobile elevating work platforms. The AEM manual can be in the storage box but it is not required by the relevant ANSI standards and it is not a substitute for either the ANSI Manual of Responsibilities or the Skyjack Operating Manual.
