MAINTENANCE TIPS ON SLIDES AND STABILIZERS
BY GARY MOTLEY
MASTER CERTIFIED TECHNICIAN
Slides are a very popular option on current
RV's.
Slides are probably the post popular innovation on RV’s in the last 15 or so years. Automatic stabilizers are also a very popular option. You will notice I used stabilizers not jacks. Any of the current technical information refers to these as stabilizers not jacks. Do not use these as jacks as this is a safety concern.
To get most of my information for this article I asked my technicians in our
shop to give me their ideas based on jobs we have done and concerns we have
repaired that normal maintenance or proper use would have taken care of. Thanks
to Allen, Ron, Carole, John and Mark for their help.
PROPER USE, MAINTENANCE AND CARE OF SLIDES
1. Make sure all travel locks, travel nuts and spring locks are in the proper position before attempting to operate a slide.
Always use travel locks.
2. Cabinet doors, drawer fronts, etc. can create problems when extending or
retracting slides. Be sure they are positioned properly for this purpose. I have
seen some pretty ingenious ideas to keep them from opening while traveling.
Often they can come out and when the slide is extending they are not visible. If
they have come out you will not know. This is the reason for these devices.
3. Do not use the top of a retracted slide for storage.
4. Make sure there is no debris on the top of the slide before retracting or
extending. Clean the top of the slide awning or slide. This is a good idea each
time.
5. All lower compartment doors should be closed and the area below the slide
clear of obstructions before retracting.
6. A slide is designed to operate properly with the weight the factory installs.
A small amount of additional weight is acceptable. Use judgment when storing
additional weight on the slide. This is also true for slide bays. Put the rock
collection elsewhere. On a side note, be aware of overall weight factors for
your RV.
7. Always check for obstruction in front of the slide before retracting. The
same is true for extending.
8. Keep the slide tracks, equalizer gears, etc. cleaned and properly lubed. Use
only soft brushes to prevent scratching the hydraulic cylinder extended rams.
9. When slide rams are extended for long periods of time, a slight coating of
hydraulic oil can help prevent the polished ram from rusting or pitting. This is
particularly true in salt air. Clean it before retracting to remove dust, etc.
10. Keep an eye on the floor in front of the slide when the slide is extended.
Abnormal wear would indicate a need to adjust the slide.
11. On most slides the top hits first when retracting. The ram(s) then pull the
bottom in to seal. The opposite is true when expanding.
12. The retract/expand ram(s) on most slide rooms is not affixed positive to the
bracket on the slide itself. The nut is generally not pulled tight to the
bracket. This is to allow the ram to work up and down in the bracket.
13. There are numerous slide systems. Each one has a different adjustment
procedure. When adjusting be sure the guidelines from the slide system
manufacturer are followed.
There are numerous slides systems and seals.
A typical slide seal sweep.
14. Lubricate the slide flaps (sweeps) and seals periodically for best results. Several companies make a spray for slide sweeps.
Slide sweep lubricants.
15. Periodically inspect the underside of your extended slide for unusual wear
patterns and adjust or repair as needed.
16. The in and out function of the slide can cause damage to the main side wall
or the inside/outside seal flanges. This can be done by continuing to ask the
slide to move after it is fully extended or retracted. Too much pressure can
cause the slide room seal flanges or side wall to bend or break loose. If your
slide does not have a means to prevent further movement when the seals are fully
engaged, do not continue pushing the button.
17. Many slides have an electrical switch called a potentiometer which is a
device to prevent excessive slide seal pressure. These devices are adjustable.
Proper adjustment is critical. Read your manual or contact qualified personnel.
18. At one time one of these potentiometer systems had an electronic defect. TV
remotes and garage door remotes could cause the slide room to activate. The fix
for this was to put a switch in the 12VDC line side of the switch and turn it
off unless being used.
PROPER USE, MAINTENANCE AND CARE OF STABILIZERS
1. Keep the springs clean and properly attached. Replace them if they appear to be stretching.
Coat the rams with hydraulic fluid to help prevent rust. Always keep the rams and springs clean.
2. If any stabilizers bleed down when extended there is a leak or other concern
that needs immediate attention.
3. Stabilizer pads should have stable and fairly flat surfaces to rest on when
the ram is extended. A sloping or unstable contact surface could cause slipping
or side load on the stabilizer. (Kwikee had a recall on their bolts that hold
the foot on. Check with your dealer)
4. The cleaning and long term extension of the rams dictates care much like the
slide rooms.
5. When extending stabilizers, follow your owner manual as far as the sequence
of which stabilizer to extend when. Extending them in an improper sequence can
put undue stress and strain on the windshield, chassis, and slide room openings.
I have seen many windshields pop out or crack as a result of this. I have also
seen main body sidewalls crack from this. These cracks generally originate at
the corners of the slide room openings.
6. Stabilizers often have lights and buzzers to indicate when one stabilizer is
still down. If you ever suspect a problem with one of these, check it out for
proper operation.
MAINTENANCE COMMON TO SLIDES AND STABILIZERS
1. Read your manual to determine proper maintenance intervals. For carefree
operation always follow proper maintenance procedures.
2. Receiving installation maintenance and user information for any new part or
accessory installed on your RV is a must. This information is crucial in helping
you get the most enjoyment of the installed item(s). Fill out and return all
warranty. This is sometimes for your safety and an opportunity to receive
updates and new product information in relation to the item(s) purchased. Have
this information available for technicians if service is ever needed. The serial
number and model number can be very helpful when technicians are gathering
information to service the item(s).
3. Know where all the 12VDC fuses and circuit breakers are located for these
features and check these first if you think you have a problem. Have extra fuses
particularly if they are no readily available at local suppliers.
Keep battery tops clean & connections tight. Know where the 12VDC fuses are and have spares.
4. As in some of my previous articles I want to stress the importance of battery
maintenance, clean terminals, and good ground connections.
5. Keep hydraulic reservoirs full of the proper hydraulic fluid. Clean around
the filler cap before removing the cap to help prevent unwanted contaminants in
the reservoir. When checking these reservoirs for full, stabilizers and slide
rooms should be in the retracted position.
6. In some instances the electronics and switches are exposed to road grime from
under the RV. They have come from the factory with a protective cover. It is
important this protective cover not be removed. It is a good idea to check that
it is performing properly and protecting the controls.
7. Slides and stabilizers have many different safety features as to when they
will operate. Switch on or off, Stabilizers up or down, etc. Always refer to the
manual if they are not performing and make certain all these settings are met.
8. Most manuals advise the RV should be level with the stabilizers extended
firmly before the slide is operated in or out.
9. The rubber seals on hydraulic rams should be protected from improper
solvents and cleaners.
Thank you for reading this article. Use these points to improve the long time enjoyment of your RV.
