7.5 Adjusting the 90° and Mast Stowed Limit Switches
Before delivery of a new system, all switches are properly set and tested at the factory and
normally no switch adjustment is necessary. However, if a switch needs adjusted, for example if
the actuator was replaced or if the mounting surface is not flat, follow the steps outlined in this
section to make the adjustment.
Every 6 Months
(3 months in salt
water
environment)
If the mast remains idle for long
periods of time, operate the mast to
full extension at least once every six
months (3 months in salt water
environment).
Exercise mast.
Every 6 Months
With the mast fully stowed, carefully
lift up on the RCP housing (do not lift
by the light fixtures). The RCP
housing should not have any
mechanical play allowing it to
bounce when being transported on a
vehicle.
If mechanical play is observed,
adjust the mast stowed limit switch
position to allow the RCP to drive
tightly into the saddle according to
Section 7.5.3.
Every 6 Months
Extend the mast to the 90° position
and make sure the mast is rigidly
driven into the rubber pad below the
mast. There should be no mast
wobble observed when pulling on the
base tube.
If the mast shows mechanical play,
adjust the mast 90° limit switch
according to Section 7.5.2.
Yearly
Test the function of the emergency
stop button to ensure it is working
properly.
Replace defective parts.
