Mast Maintenance
The mast on the PCMS unit has the signboard and the solar panels attached. On most units a
hydraulic pump system that is connected to the batteries in the battery box, raises and lowers
the mast. However some smaller units rely on a manual hand winch to raise and lower the
mast.

Hydraulic Lift System for Mast
NOTE
For safety during transport Ver-Mac disconnects power to the hydraulic pump.
Make sure the power feed is connected to the battery terminals inside the battery
compartment.

Raising and Lowering the Mast
NOTE
Before raising or lowering the mast, open battery box and check that the
hydraulic bypass valve is tight.
1. To raise mast, open control box, and flip switch to Sign Up.
The mast rises automatically.
2. To lower mast, reverse the procedure.
The hydraulic system used to raise and lower the mast does not require any
regularly scheduled maintenance beyond periodic checking of the fluid.
