2. MAINTENANCE INSTRUCTIONS
WARNING
To prevent serious injury or death from a falling vehicle, all inspection and maintenance procedures must be
performed after the lift has been removed from service. Position the lifts so you have clear access to all sides
of the lift for inspection and service.
The owner must inspect, or appoint a knowledgeable person to inspect, the lift. Visual inspection should be made
before each use of lift, checking for abnormal conditions. Regular inspections should be made weekly for daily
use and monthly for intermittent use. Each jack must be inspected immediately if subjected to an abnormal load
or shock. Any jack which appears to be damaged in any way, is found to be badly worn, or operates
abnormally shall be removed from service until necessary repairs are made.
1.
All warning and capacity labels should be readable and complete. Wash external surfaces of jack, labels,
and decals with a mild soap solution.
2.1 Lubrication
1.
Lubricate the pneumatic wheels, swivel caster, and sliding portions of the jack monthly.
2.2 Air Valve Cleaning Instructions
