Special Limitations

Travel with the platform raised is limited to creep speed range. Elevating the platform is limited to firm, level surfaces only.

The elevating function shall ONLY be used when the work platform is level and on a firm surface.
The work platform is NOT intended to be driven over uneven, rough, or soft terrain.

Platform Capacity
The maximum platform capacity for the aerial platform is stated in the "Specifications".

DO NOT exceed the maximum platform capacity or the platform occupancy limits for this machine.

Manual Force
Manual force is the force applied by the occupants to objects such as walls or other structures outside the work platform.
Refer to the platform capacity decal on the machine for specific maximum allowable manual force information.
The maximum allowable manual force varies depending on wind speed. The maximum allowable wind speed is 12.5 m/s (28 mph).

DO NOT exceed the maximum amount of manual force for this machine.

Drive/Lift Pothole Protector Interlock
The aerial platform drive and lift functions are interlocked through a limit switch inside the chassis that senses whether or not the pothole protection linkage is locked into position. The drive/lift pothole interlock operates when the platform is elevated approximately 1.8 m (6').
If an obstruction under the skids, or some other impairment prevents the skids from locking into position, the drive and steer functions will not operate and an alarm will sound.
Lower the platform and remove the obstruction when the drive/lift pothole protector interlock alarm sounds.

Drive/Lift Level Sensor Interlock
The aerial platform drive and lift functions are interlocked through a level sensor system. The drive/lift level sensor interlock operates when the platform is elevated approximately 1.8 m (6').
If the chassis is tilted too far out of level, the drive and lift functions will not operate and an alarm will sound. Refer to the machine specifications for the level sensor factory setting.
Lower the platform and drive to a level surface when the drive/lift level sensor alarm sounds.
The drive/lift level sensor system is for added protection and does not justify operating on anything other than firm, flat, level surfaces.

Lowering Alarm
When the joystick is moved out of neutral to lower the platform, the alarm emits a loud beeping sound to warn personnel in the work area to stand clear.

Pinch points exist on the scissors structure. Death or serious injury will result if the scissors structure lowers onto personnel within the scissors arms or under the raised platform. Stand clear while raising and lowering the platform.
Be careful when lowering the platform. Keep hands and fingers away from the scissors structures components.

Lowering Interrupt
When the platform is lowered to about 1.8 m (6') lowering stops. The platform will not lower for five seconds regardless of the control position to allow personnel to clear the area of the scissors before the platform completely lowers.
Center the control in neutral to reset the lowering function, then continue to lower the platform.
When the platform is below 1.8 m (6') and the control is moved to lower the platform, there is a 1.5 second delay before movement begins.

Overload Protection
When the load in the platform is near or at rated capacity, an alarm will sound and the red light on the lower controls will ash.
The alarm and light warn the operator that the platform is close to becoming overloaded. All functions remain fully operational.

The aerial platform can tip over if it becomes unstable. Death or serious injury will result from a tip-over accident. Do not exceed the capacity values indicated on the platform rating placard.
If the platform is fully lowered and is overloaded, when it is elevated just past 1.8 m (6'), a control module will stop the lift and drive functions and the alarm will sound and the warning light will ash. The platform can still be lowered to remove the excess load.
If the platform is elevated just past 1.8 m (6') and material is added to the platform overloading it, a control module will stop the lift, drive and lower functions and the alarm will sound and the warning light will ash. In this case, remove the load in excess of rated capacity and cycle the emergency stop button at the upper controls to return to normal operation.

11. Drive the aerial platform forward or reverse and then stop to reset the parking brakes.
12. Verify that the drive system and brakes operate properly before operating the aerial platform.

Driving

The aerial platform can tip over if it becomes unstable. Death or serious injury will result from a tip-over accident. Do not drive on ramps that exceed 25 percent grade, or where conditions of the ramp could cause driving to be hazardous.
Use a winch to load and unload the aerial platform on ramps that exceed the gradeability specification for the machine. Refer to "Specifications". A winch may also be used when poor traction, uneven surfaces, or stepped ramp transitions make driving hazardous.
Drive the aerial platform onto the transport vehicle if a winch is not available and the ramp incline is within the grade capability of the aerial platform.
Use the following procedure to drive the aerial platform onto the transport vehicle.

1. Position the transport vehicle so the aerial platform will not roll forward after it is loaded.
2. Chock the vehicle wheels so it cannot roll away from the ramp while the aerial platform is loaded.
3. Remove any unnecessary tools, materials, or other loose objects from the platform.
   
   The extension deck is free to move when the extension handle locks are disengaged. Personal injury may result from accidentally extending or retracting the deck. Make certain both extension handle locks are fully engaged when the deck is extended in the working position and when it is stowed. Do not attempt to extend or retract the platform unless the aerial platform is on a level surface.
4. Fully retract the platform extension deck and ensure that it is secured in position, with the latch handle locks fully engaged. Fully lower the platform.
5. Drive the aerial platform to the foot of the loading ramp with the front wheels nearest the ramp. Make sure the aerial platform is centered with the ramps and that the steering wheels are straight.
6. On S3220E/S3226E/S4726E/S4732E machines, place the drive range switch in low (turtle) for climbing or descending a ramp.
7. Drive the aerial platform on or off the transport vehicle in a straight line through the grade transitions with minimal turning.

Hoisting
Use a four point sling arrangement attached to the lifting lugs when hoisting the aerial platform. Machine damage can occur if the sling is attached anywhere else.

The potential for an accident increases when the aerial platform is lifted using improper equipment and/or lifting techniques. Death or serious injury could result from such accidents. Use proper equipment and lifting techniques when lifting the aerial platform.
Know the weight of the aerial platform and the capacity of the lifting devices before hoisting.

• Lifting devices include the hoist or crane, chains, straps, cables, hooks, sheaves, shackles, slings, and other hardware used to support the machine.
• The empty vehicle weight is stamped on the serial number placard and is listed in the machine specifications.

The user assumes all responsibility for:

• Making sure the equipment used is capable of supporting the weight of the aerial platform.
• Making sure all manufacturer's instructions and warnings, regulations and safety rules of their employer and/or any state or federal law are followed.

Use the following procedure to hoist the aerial platform onto the transport vehicle:

1. Properly stow the aerial platform.
2. Inspect the front lifting lugs and the rear lifting lugs to make sure they are free of cracks and are in good condition. There are two lugs on the rear of the chassis and two on the front. Have any damage repaired by a qualified service technician before attempting to hoist the machine.
3. Remove all personnel, tools, materials, or other loose objects from the platform.
4. Connect the chains or straps to the lifting lugs using bolted shackles. Hooks that fit properly in the lugs and that have latching mechanisms to prevent them from falling out under a slack line condition may also be used.
   Do not run the sling cable through the lifting lugs.
   • Cable damage and/or failure can result from the cable contacting the sharp corners of the lug.
   • There is no effective way of putting a corner protector in the hole of the lug.

Storage

No service is required when storing, or removing the machine from service, for less than one week.
If the machine functions are not cycled for longer than one week, grease exposed cylinder rods with a light, white lithium grease and periodically charge the batteries.

Maintenance

Always block the elevating assembly whenever it is necessary to perform maintenance while the platform is elevated.

Hydraulic Fluid
The hydraulic fluid reservoir is located in the hydraulic tray.

Note
Never add fluid if the platform is elevated.

Check Hydraulic Fluid

1. Make sure that the platform is fully lowered.
2. Visually check to make sure the fluid is visible in the sight gauge.
3. If necessary, remove the filler cap and add fluid of the proper type. Replace the cap making sure it is tightly in place. Refer to the machine specifications.

Battery Maintenance

Hazard of explosive gas mixture. Keep sparks, flame, and smoking material away from batteries.
Always wear safety glasses when working near batteries.
Battery fluid is highly corrosive. Thoroughly rinse away any spilled fluid with clean water.
Always replace batteries with manufacturer approved replacements.

• Check the battery uid level daily, especially if the machine is being used in a warm, dry climate.
• If electrolyte level is lower than 6 mm (¼') above the plates add distilled water only. DO NOT use tap water with high mineral content, as it will shorten battery life.
• Keep the terminals and tops of the batteries clean.
• Refer to the Service Manual to extend battery life and for complete service instructions.

Always use manufacturer approved replacement parts.

Battery Charging
Charge the batteries at the end of each work shift or sooner if the batteries have been discharged.

Charge the batteries in a well ventilated area.
Do not charge the batteries when the machine is near a source of sparks or flames.
Permanent damage to the batteries will result if the batteries are not immediately recharged after discharging.
Never disconnect the cables from the batteries when the charger is operating.
Keep the charger dry.
Use the following procedure to charge the batteries.

1. The battery disconnect switch is at the rear of the chassis, below the entry step. Turn the battery disconnect switch off.
2. Check the battery water level. Add water to individual cells only if the plates are exposed. Replace the battery caps.
3. Plug the charger into a properly grounded AC outlet using a 3 conductor, 12 gauge or larger extension cord. The extension cord must be as short as possible and in good electrical condition.
4. Leave the charger plugged in until it shuts itself off.
5. Unplug the extension cord after the charger turns itself off. Allow the batteries to cool off after charging.
6. Check the battery water level. Add water to individual cells only if the plates are exposed. Replace the battery caps.

Inspection and Maintenance Schedule

Frequency and extent of periodic examinations may depend on national regulations.
The Complete Inspection consists of periodic visual and operational checks, along with periodic minor adjustments that assure proper performance. Daily inspection will prevent abnormal wear and prolong the life of all systems. The inspection and maintenance schedule should be performed at the specified intervals and after prolonged periods of storage before returning the machine to service. Inspection and maintenance shall be performed by personnel who are trained and familiar with mechanical and electrical procedures.

Before performing preventative maintenance, familiarize yourself with the operation of the machine. Always block the elevating assembly whenever it is necessary to perform maintenance while the platform is elevated.
The daily preventative maintenance checklist has been designed for machine service and maintenance. Please photocopy the Daily Preventative Maintenance Checklist and use the checklist when inspecting the machine.
