INTRODUCTION INTRODUCTION This manual covers the operation of the UL25, UL32 and UL40 work platforms. This manual must be stored on the machine at all times. Read, understand and follow all safety rules and operating instructions before attempting to operate the machine.
The platform lift function is interlocked through a level sensor system. If the chassis is tilted more than 1.5 degrees in either direction, an alarm will sound when the power is turned on and the lift function will not operate. When the alarm sounds, only the platform lower function will operate. Page 2 - 8 UL25/UL32/UL40...
9. Check that all guardrails are in place and all fasteners are properly tightened. 10. Inspect the machine thoroughly for cracked welds and structural damage, loose or missing hardware, hydraulic leaks, damaged control cable and loose wire connections. UL25/UL32/UL40 Page 2 - 11...
2. Adjust the outriggers so that the platform is tilted by more than 1.5 degrees. 3. Verify that the tilt alarm sounds and using the ground control panel, the platform should not elevate. 4. Repeat steps 1 to 3 using the platform controls. Page 2 - 12 UL25/UL32/UL40...
9. Repeat tests 4 & 5 from the platform controls. 10. Push the platform emergency stop switch to verify proper operation. All machine functions should be disabled. Pull out the platform emergency stop switch to resume. UL25/UL32/UL40 Page 2 - 13...

For DC models, prior to transportation, disconnect the plug from the battery box and remove the battery box from the rear of the machine. C A U T I O N The battery box is heavy (23.6kg/52 lbs). Lift properly to avoid back injury. Page 2 - 16 UL25/UL32/UL40...
Gradually counterbalance the unit’s weight by applying an upward force on the T-handle. This allows the unit to settle gently on the wheels avoiding undue impact on the unit. 5. Return the T-handle to the stored position making sure that the locking pin engages the T-han- dle. Page 2 - 18 UL25/UL32/UL40...
5. While holding the tilt back frame, remove the retaining pin and raise the tilt back assembly to the stowed position. 6. Secure with the retaining pin, making sure that the retaining pin is fully inserted and that the hair pin retainer is installed. UL25/UL32/UL40 Page 2 - 19...
