PROBLEM POSSIBLE CAUSE / SOLUTION
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 • Acme screw and drive nuts
• belt pulleys and shafts, including keys • Acme screw lubrication (see Note 1)
• motor • pads and rollers
• 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.
