SECTION 4. MACHINE OPERATION
4.1
DESCRIPTION
This machine is a self-propelled hydraulic lift equipped with a work platform on an elevating scissor mechanism. Vibrations emitted by these machines are not hazardous to an operator in the work platform. The equivalent continuous A-Weighted sound pressure level at the work platform is less than 70 dB(A).
The primary operator control station is in the platform. From this control station, the operator can drive and steer the machine in both forward and reverse directions. The machine has a Ground Control Station which will override the Platform
Control Station. Ground Controls operate lift and lower and are to be used in an emergency to lower the platform to the ground should the operator in the platform be unable to do so. Ground
Control is also to be used in Pre-Start Inspection.
4.2
POWER SELECT
Platform/Ground Select
The Platform/Ground Select switch directs power to the Ground or Platform controls as selected. For power, the POWER/EMER-
GENCY STOP switch must also be pulled out (on).
4.3
RAISING AND LOWERING
Raising & Lowering
To raise or lower the platform, either use Lift or Lower function and hold switch until desired elevation is reached.
DO NOT LOWER WITHOUT COMPLETELY RETRACTING PLATFORM EXTENSION.

LEVELING JACKS
Once the leveling jacks leave the stowed position (fully retracted) but are not fully extended, the lift and drive functions are cut out.
After all 4 jacks are extended and touch a solid surface only the drive function is cut out. Drive function is restored once the jacks are stowed (fully retracted) again.
4. Remove the two pins from rear handrail, lift up and fold gate down onto platform deck.
5. Lift up left handrail, fold handrail down onto platform deck.
6. Lift up right handrail, fold handrail down onto platform deck.
4.5
PLATFORM EXTENSION
The machine is equipped with a mechanically extendible deck.
To extend the deck, lift handle up on the left and right side of the platform to release the latch and use the handle to push the extendible deck out. When the deck reaches the end of its travel, push handle down to latch, this will lock and hold the deck in place. To retract the deck, reverse operation.
4.7
STEERING
Position thumb switch on drive/lift/steer controller to right for steering right, or to left for steering left.
TO AVOID LOSS OF TRAVEL CONTROL OR UPSET ON GRADES AND SIDE
SLOPES, DO NOT DRIVE MACHINE ON GRADES OR SIDE SLOPES EXCEEDING
THOSE SPECIFIED ON WARNING PLACARD AT PLATFORM.
4.6
PLATFORM HANDRAILS FOLD DOWN PROCEDURE (IF
EQUIPPED)
1. Remove the two pins from platform extension gate and fold gate to the left side handrail.
2. Remove the pin from extension left side handrail, lift up and fold down handrail onto platform deck.
3. Remove the pin from extension right side handrail, lift up and fold down onto platform deck.

Traveling Forward and Reverse
1. At platform controls, pull out emergency stop switch and select the drive switch.
2. Position drive controller to forward or reverse as desired.
DIRECTION OF DRIVE AND STEER MOVEMENT MAY BE OPPOSITE FROM NOR-
MAL OPERATION. BEFORE DRIVING, LOCATE THE BLACK/WHITE ORIENTA-
TION ARROWS ON BOTH THE CHASSIS AND THE PLATFORM CONTROLS. MOVE
THE DRIVE CONTROLS IN A DIRECTION MATCHING THE ORIENTATION
ARROWS.

SHUT DOWN AND PARK
NOTE:
When parking overnight, batteries should be charged properly to ensure readiness for next workday.
To shut down and park the machine, the procedures are as follows:
1. Drive machine to a reasonably well protected area.
2. Ensure platform is fully lowered.
3. Push in the Emergency Stop at platform controls.
4. Push in the Emergency Stop at ground controls. Position platform/ground select switch to center off.
5. If necessary, cover Platform Controls to protect instruction placards, warning decals and operating controls from hostile environment.
6. Chock at least two wheels when parking machine for an extended period of time.
IF TILT ALARM IS ON WHEN PLATFORM IS RAISED, STOP DRIVING AND
LOWER PLATFORM COMPLETELY, THEN REPOSITION MACHINE SO THAT IT IS
LEVEL BEFORE RAISING PLATFORM.

SAFETY PROP
SAFETY PROP MUST BE USED WHEN MAINTENANCE REQUIRES SIZZOR ARMS
TO BE RAISED.
1. To engage safety prop, raise platform, pull ring to release safety prop, then rotate prop clockwise until it hangs vertically. Lower the platform until the safety prop rests between the two extended cross-shafts.
2. To store safety prop, reverse operation of step 1.
4.10 BATTERY CHARGING PROCEDURE
The battery charger receptacle is located at the front of the machine. The receptacle is located in the molded front panel.
1. Connect the charger receptacle to a 115 volt (220 volt) power outlet with a 15 amp minimum capacity.
2. The batteries are charged fully when the 100% LED is lit. At this time, the charger will shut off automatically.
NOTE:
Discharged batteries will take approximately 23 hours to charge.
4.11 TIE DOWN/LIFTING
Tie Down
1. Place platform in stowed position and retract deck extension.
2. Remove all loose items from machine.
3. Secure the chassis using straps or chains of adequate strength.
Lifting
NOTE:
See manufacturer’s nameplate for gross weight of machine as originally manufactured.
1. Place platform in stowed position and retract deck extension.
2. Remove all loose items from machine.
3. Properly adjust rigging to prevent damage to machine and so machine remains level.
NOTICE
DO NOT ATTEMPT TO LIFT MACHINE WITH A FORK TRUCK. FORK POCKETS
LOCATED UNDER BATTERY PACKS ARE PROVIDED FOR LIFTING BATTERIES
ONLY.
