LIPPERT Happijac Camper Jacks
General Precautions
- Load & unload camper on basically level ground, never on an obvious grade.
- Use 12” sq. 3/4” plywood support pads under each jack to prevent sinking into soft ground, sand, or hot asphalt
- Use extreme caution when the wind is blowing. Avoid storing camper in windy, unsheltered areas and prevent snow accumulation on camper roof.
- Secure camper with tie downs when stored outdoors.
- Camper should be supported on a sturdy base during storage to prevent damage to camper floor and the wing walls. When living in camper, the floor should be firmly supported.
- When leveling with the camper on the truck – REMOVE TIEDOWNS. The jacks are not designed with the capacity to lift both camper & truck. Overloading the jacks can result in property damage and/or personal injury or death.
- When the camper is being supported (stored) on the jacks alone and except when loading and unloading, It should be stored as close to the ground as possible (least possible jack extension). This provides maximum lateral stability.
Loading Your Camper
Begin by raising the front of the camper a few inches (4” – 6”) higher than the rear. Maintain this differential until the camper is resting on the truck bed. Never raise the back of the camper higher than the front. Working front to back or side to side raise the camper in small increments checking continually to ensure that all jacks are on the ground and the camper remains level side to side (within 3 – 4 inches). Raise camper, until the bottom of the camper is higher than truck bed by 3” or more. BE CAREFUL NOT TO OVER- EXTEND THE JACKS. Slowly back the truck under the camper. It is a good idea, when possible, to have a spotter. Make sure truck and camper are aligned so as not to hit the jacks or the camper with truck fenders or wheel wells.. Connect electrical cables while accessible. Lower camper onto truck bed making sure the rear of the camper contactsthe truck bed first to avoid hitting the cab of the truck with the camper overhang. Completely retract all 4 jacks to one inch of physical stop. If the stop is reached, back the jack out of the stop by 1”. Jacks left retracted in the hard stop for prolonged periods can become bound and may be difficult to break free.
Unloading Your Camper
Make sure all tiedowns are disconnected. Disconnect electrical connections as
soon as they become accessible. Run all 4 jacks to the ground then raise the
front of the camper 4” to 6” higher than the rear. Maintain this differential
throughout the unloading process. Never let the back of the camper become
higher than the front. Raise the camper clear off the truck bed by 3” to 4”. )
BE CAREFUL NOT TO OVER-EXTEND THE JACKS. Slowly drive the truck forward, being
very careful not to hit the jacks or the camper. Caution: Fill holes or move
rocks that could cause the truck to pitch into the jacks or the camper. Once
the truck is clear, lower the camper, maintaining the slight nose up
attitude, lower in small increments checking continually to ensure that all
jacks are on the ground and the camper remains level side to side (within 3 –
4 inches). If storing the camper, it is best to support the camper with
blocks, sawhorses, etc. If storing on jacks alone, lower to lowest possible
storage height. (Being careful of sewage drains, etc.) Stability increases the
lower the jacks can be retracted. If the camper is to be utilized while off
the truck, stabilizing jacks under the camper floor will not only add to
stability but provide a more comfortable camping experience.
Manual Operation
CAUTION: Always insert the crank handle before releasing the manual locking lever. This lever disconnects the jack from the motor head (or lock cap in the case of manual jacks). These are the primary locking mechanisms. While highly unlikely it is not impossible that there could be a load induced retraction of the jack. When not properly locked. When the crank handle is inserted, even if the locking lever is in the unlocked position, the jack will not autoretract under load.
To manually operate, first insert the crank handle, then release the Locking Lever (Down Position) at top of jack. Be sure to reset Locking Lever (Up Position) BEFORE removing the crank handle.
- Crank clockwise to Lower Camper (retract jack)
- Counterclockwise to Raise Camper (extend jack)
Maintenance
- Frequently – check all mounting screws and other hardware for tightness and proper jack alignment.
- Every 6 months – wax mounting brackets and both inner and outer tubes of jack leg with automotive wax. This not only protects from corrosion but improves jack performance by acting as a dry lubricant on the inner leg.
- After periods of non-use, or anytime jack seems to labor more than usual, remove dust cap and place a few drops of light oil, such as 3 in 1R into the oil hole in the crank socket.
- Alternatively, wrap a rag around socket to catch overspray and use a light spray lubricant such as silicone sprayed liberally around the crank socket. Wipe away overspray.
- Run the jack to distribute the lubricant. Spray Here
- Keep dust caps on anytime crank is not installed.
