TROUBLESHOOTING and MAINTENANCE
TROUBLESHOOTING
PROBLEM
Platform does not operate
properly in the UP or the
DOWN direction.
Platform controls do
not operate.
MAINTENANCE
EVERY (12) MONTHS (more frequently if the lift is used under strenuous conditions), have the
lift undergo a complete inspection by an authorized Bruno dealer and have this dealer make any
necessary repairs/replacements. Having the VPL-3100 serviced by someone other than an
authorized Bruno dealer will render your warranty null and void.
1. Check the suspension/drive system:
• belts, including belt tension
• belt pulleys and shafts, including keys
• motor
• bearing (see Note 1)
2. Verify that the platform stops within 1/2" (13 mm) of the landing.
3. Inspect the platform controls and the call/send controls.
4. Inspect the wiring and connectors (see Note 2).
5. Verify general cleanliness of the unit. (It is not uncommon to remove mouse nests.)
NOTE 1: Bruno uses a special grease for better performance over a wider temperature range,
especially in colder environments. Please use Mobil AVIATION GREASE SHC 100 (Bruno
part no. LUB-00114).
NOTE 2: To help protect connector pins from moisture, apply dielectric grease to connectors
exposed to the elements (ex. rain, snow).
EVERY (2) MONTHS
1. Units with electronic door interlock: verify that the platform does not move when any door is not closed
and locked.
2. Units with GAL door interlock: verify that the platform does not move more than 2" (51 mm) in
relation to the landing.
3. Verify that the safety pans (under the platform) are working properly.
NOTE: Do not work under the platform when testing operation.
NOTE: Please reference ILS-01444 (Maintenance Control Plan for Vertical Platform Lifts) for units
that require ASME A18.1 - 2017 and newer compliance.
