4. A periodic coating of light lubricating oil to all rotating and sliding portions of the jack
will help to prevent rust and assure that the wheels move freely.
5. Lower the saddle to its lowest position when not in use.
6. When jack is not in use, tip it forward until it rests on the wheels and use extra
support to hold the jack as shown in figure 3. This allows trapped water to drain
from inside the cylinder.

Inspections should be made before each use of jack, checking for abnormal conditions. Regular inspections should
be made weekly for daily use and monthly for intermittent use.
1. Inspect air hose for leaks or kinks. Replace if necessary.
2. Air control valve should operate freely. Wheels should rotate freely.
