Have you lubricated all the moving parts thoroughly?
Does the battery have a good charge?
Does Bueller have any ideas?
I read this forum not because I think I can help, but because I want to have an idea of what to look for when I have problem. Please post your solution, er' if you find one!
Puma's Palomino manual which is available on line does have steps for making an adjustment. Go to a DEALER!
Here is what the manual says...
Before extending the room, check the exterior of the unit to
be sure the room will not hit anything outside when it is fully
extended. Locate the rocker switch that reads ‘SLIDE ROOM’.
Hold the switch in the ‘OUT’ position. (Note: You may hear a
low grinding noise at the initial start of the operation. This is
normal. It’s the sound of the piston shafts traveling through the
free travel area of the brackets.) Continue to hold the switch
down until the room stops moving. If the room stops moving
before it is fully extended, the piston shafts may need to be
adjusted. (Note: If this happens, contact your dealer and set
up a service appointment for adjustment.) To bring the room
in, reverse the procedure.If power fails or the room does not
function electrically, you can manually operate the room.
NOTE: FOR OPTIMUM PERFORMANCE, THE SLIDE OUT
SYSTEM REQUIRES FULL BATTERY CURRENT AND
VOLTAGE. THE BATTERY MUST BE MAINTAINED AT FULL
CAPACITY. IF THE BATTERY IS FULLY CHARGED AND YOU
STILL DO NOT HAVE POWER, CHECK THE TERMINALS
AND OTHER CONNECTIONS AT THE BATTERY.
DO NOT PERFORM ANY MAINTENANCE
WORK ON YOUR SLIDE OUT SYSTEM
WITHOUT FIRST DISCONNECTING THE BATTERY. FAILURE
TO DO SO COULD RESULT IN SERIOUS PERSONAL INJURY
