2. With a 7/16” open end wrench, (Fig. 6)
loosen the 1/4” - 20 hex nut that is located on
the right side of the brass post next to the
threaded rod. Then use a hex wrench to back out
the set screw that threads through the nut until
the brass tensioning collar can be turned.
3. Rotate the brass tensioning collar with
vertical grooves, so it tightens against the rubber
washer. Note: a drop of oil on the rubber washer
eases the rotation of the brass collar.
4. Be certain when you tighten the brass collar
the set screw seats in one of the vertical grooves.
5. Tighten the 1/4”-20 nut with the 7/16”
wrench again and the adjustment is complete.
USING YOUR MAST-R-LIFT
To raise your router, turn the height adjustment
handle clockwise. To lower, turn the handle
counter-clockwise. Keep in mind that one
complete revolution equals 1/16” of change.
When your adjustment is complete, remove the
handle and place somewhere off the work
surface for safety. Refer to the chart below for
fractional and decimal adjustments based on
amount of revolutions made.

RE-ADJUSTING THE THREAD TENSIONING
All JessEm Lifts feature our patented thread
tensioning design. This feature is why it is not
necessary to lock the router into position after
setting the cutting height. The design keeps
tension on the position wherever you set the
height. Thread tension is set at the factory and
depending on the amount of use you may have to
reset this adjustment periodically. If the bit height
ever begins to change (or drop) during use, the
thread tensioning likely needs to be reset.
