6400 SERIES TONGUE JACK
ASSEMBLY
Minimal maintenance is required to keep your tongue jack
looking new and in good working order. Protect the finish
by keeping it clean and waxed. Lubrication is needed
if the jack cranks roughly or produces a grinding noise
when operated. With weight off the jack remove jack from
tongue. Remove end cap (MM). (See parts list on back
page.) Remove pin (1) holding handle in place. Remove
handle and miter gear (2). Turn jack upside down and
shake gently to allow miter gear (3) to drop out. Align
dowel pin (4) with hole in side of outer post assembly.
Gently tap outer post assembly sideways allowing dowel
pin to slip free from jackscrew and drop through hole in
outer tube. Tap top of jackscrew to remove inner tube
assembly. Do not attempt to remove screw from inner
tube. Lubricate screw, thrust bearing (FF), and miter
gears (2) and (3) with grease.
MAINTENANCE
Bolt-on Place jack on trailer tongue in a location that
avoids interference with the boat, trailer and tow vehicle
during all conditions of use. Make sure the jack cannot
contact the tow vehicle when making tight turns. Tighten
all bolts evenly.
Weld-on Weld on jack brackets need to be installed by
a competent welder. Determine location per instruction
above.
After bracket is painted, assemble jack according to the
parts drawing and assembly instructions above. Note that
bolts (QQ) are self-threading and require considerable
installation force.
A-Frame Insert jack through hole in coupler and secure
with bolts, lock washers, and nuts. A removable wheel or
foot can be purchased separately. CAUTION When
using the removable wheel with tongue weights over
250lb/114Kg, a No. 6612 support plate should be
securely welded to the bottom of the trailer frame.
Failure to do so could result in jack and coupler
damage.
MOUNTING
When jack reaches either end of its travel do not force
handle or damage to the jack will result. When moving
trailer by hand, crank jack to lowest position. Do not use
the jack as a convenient hand hold. Avoid rolling jack over
rough or soft surfaces. Raise jack completely before tow-
ing.
WARNING Use of a swivel type jack without the
swivel handle completely engaged could result in
the trailer tongue suddenly dropping and could
cause personal injury.
CAUTION Loads in excess of rating shown on
jack label will cause accelerated wear and possi-
ble failure. This jack is not for highway use. Never
tow trailer with load applied to jack.
