AIRSTREAM INTERNATIONAL TRAILER OWNERS MANUAL
If an electrical failure should ever occur the emergency handle may be
inserted into the jack post and the jack can be raised or lowered. Access can
be obtained by twisting level cap off.
If power head is removed the crank can still be used.
Caution:
If power head is removed it must be synchronized with the
jack post.
Caution:
Leave tow vehicle transmission in neutral when lifting both
units. Dolly wheels are not recommended. Always retract stabilizing
jacks before using your jack under load.
WARNING:
Do not use the electric toggle switch (raise and lower) with the manual
crank in place on the jack post. The crank will spin if the switch operates motor and will cause
serious injury.
Maintenance
Once a year the power head should be removed and a liberal amount of grease (preferably a grease with
high melting point) applied directly to the coupling on which the drive pin rests. DO NOT POUR OIL into
the top of the jack post.
Once a year the housing cover should be removed and the gears inspected for proper lubrication. Remove 4
screws and tap around the edges of the housing to free the cover. DO NOT insert screwdriver blade, this
may damage mating surfaces. If lubrication is needed, use Mobilith 460 grease or its equivalent.
