INTRODUCTION

SECTION A. INTRODUCTION - MAINTENANCE SAFETY PRECAUTIONS

A GENERAL

This section contains the general safety precautions which must be observed during maintenance of the aerial platform. It is of utmost importance that maintenance personnel pay strict attention to these warnings and precautions to avoid possible injury to themselves or others, or damage to the equipment. A maintenance program must be followed to ensure that the machine is safe to operate.

MODIFICATION OR ALTERATION OF AN AERIAL WORK PLATFORM SHALL BE MADE ONLY WITH WRITTEN PERMISSION FROM THE MANUFACTURER.

The specific precautions to be observed during maintenance are inserted at the appropriate point in the manual. These precautions are, for the most part, those that apply when servicing hydraulic and larger machine component parts.

Your safety, and that of others, is the first consideration when engaging in the maintenance of equipment. Always be conscious of weight. Never attempt to move heavy parts without the aid of a mechanical device. Do not allow heavy objects to rest in an unstable position. When raising a portion of the equipment, ensure that adequate support is provided.

C MAINTENANCE

FAILURE TO COMPLY WITH SAFETY PRECAUTIONS LISTED IN THIS SECTION COULD RESULT IN MACHINE DAMAGE, PERSONNEL INJURY OR DEATH AND IS A SAFETY VIOLATION.

• ENSURE REPLACEMENT PARTS OR COMPONENTS ARE IDENTICAL OR EQUIVALENT TO ORIGINAL PARTS OR COMPONENTS.

• NO SMOKING IS MANDATORY. NEVER REFUEL DURING ELECTRICAL STORMS. ENSURE THAT FUEL CAP IS CLOSED AND SECURE AT ALL OTHER TIMES.

• REMOVE ALL RINGS, WATCHES AND JEWELRY WHEN PERFORMING ANY MAINTENANCE.

• DO NOT WEAR LONG HAIR UNRESTRAINED, OR LOOSE-FITTING CLOTHING AND NECKTIES WHICH ARE APT TO BECOME CAUGHT ON OR ENTANGLED IN EQUIPMENT.

• OBSERVE AND OBEY ALL WARNINGS AND CAUTIONS ON MACHINE AND IN SERVICEMANUAL.

• KEEP OIL, GREASE, WATER, ETC. WIPED FROM STANDING SURFACES AND HAND HOLDS.

• USE CAUTION WHEN CHECKING A HOT, PRESSURIZED COOLANT SYSTEM.

• NEVER WORK UNDER AN ELEVATED BOOM UNTIL

SINCE THE MACHINE MANUFACTURER HAS NO DIRECT CONTROL OVER THE FIELD INSPECTION AND MAINTENANCE, SAFETY IN THIS AREA RESPONSIBILITY OF THE OWNER/OPERATO R.

BOOM HAS BEEN SAFELY RESTRAINED FROM ANY MOVEMENT BY BLOCKING OR OVERHEAD SLING, OR BOOM SAFETY PROP HAS BEEN ENGAGED.

• BEFORE MAKING ADJUSTMENTS, LUBRICATING OR PERFORMING ANY OTHER MAINTENANCE, SHUT OFF ALL POWER CONTROLS.

B HYDRAULIC SYSTEM SAFETY

• BATTERY SHOULD ALWAYS BE DISCONNECTED-

It should be noted that the machines hydraulic systems operate at extremely high potentially dangerous pressures. Every effort should be made to relieve any system pressure prior to disconnecting or removing any portion of the system.

DURING REPLACEMENT OF ELECTRICAL COMPONENTS.

• KEEP ALL SUPPORT EQUIPMENT AND ATTACHMENTS STOWED IN THEIR PROPER PLACE.

• USE ONLY APPROVED, NONFLAMMABLE CLEANING SOLVENTS.

Machine Orientation When Doing Function Tests

1. LIFT: Boom retracted, telescope retracted. Lift up, record time. Lift down, record time.

2. SWING: Boom at full elevation, telescope retracted. Swing the turntable to the end stop. Swing the opposite direction. Record time. Swing the other direction, record time.

3. TELESCOPE: Boom at full elevation, telescope retracted. Telescope out, record time. Telescope in, record time.

4. DRIVE: Test should be done on a smooth, level surface. Start approximately 25 feet from starting point so that the unit is at a maximum speed when starting the test. Results should be recorded for a 200 foot course. Drive forward, record time. Drive reverse, record time.

5. DRIVE (ABOVE HORIZONTAL): Test should be done on a smooth, level surface. The platform speed control knob should be selected out of creep speed. This verifies that the switches are working when the boom is above horizontal. Results should be recorded for a 50 ft. course. Drive forward, record time. Drive reverse, record time.

6. PLATFORM ROTATE: Platform level and completely rotated one direction. Rotate the opposite direction, record time. Rotate the other direction, record time.

7. JIB: Platform level and centered with the boom. Start with the jib down. Jib up, record time. Jib down, record time.

8. LOWER LIFT: Upper boom horizontal, telescoped in. Lower lift up, record time. Lower lift down, record time.

9. JIB SWING: Platform level and centered with the boom. Start with the jib horizontal. Begin with jib swing fully to left. Swing fully to right. Record time. Swing to the left, record time.

NOTE: Stop watch should be started with the function, not

with the controller or switch.

All speed tests are run from the platform.

The platform speed control knob must be at full speed. (turned clockwise completely)

The function speeds may vary due to cold thick hydraulic oil. Tests should be run with oil tempera-

ture above 100

Some flow control functions may not work with the speed control knob in the creep position.
