MAINTENANCE
3200 SERIES OWNER’S MANUAL
PURGING AIR FROM THE SYSTEM
Air that is trapped in the cylinder will cause an erratic “bumpy” condition. To expel the air, hold the affected
control open after the function has “bottomed out”. Move the function in the opposite direction and again hold
the control open. Attempt to operate the crane in a normal manner to determine if the air has been purged.
When purging is complete, reevaluate hydraulic fluid level and add fluid if necessary.
REMOTE CONTROL
The remote control is subject to corrosion and must be checked at least twice a year and more often if operated
in severe, wet conditions. To check for corrosion:
1.
Remove the cover plate and inspect for lack of luster. Metal should appear bright and untarnished.
2.
Spray the inside of the box with an ignition sealer such as Krylon.
3.
Check all connections to make sure they are tight.
