ROUTER SAFETY PRECAUTIONS
•
Never force the bit or overload the router beyond
the expectations of the tool.
•
Be sure that at least 3/4 of the shank length is
inserted securely in the router collet.
•
Never bottom out the bit in the collet. Allow 1/8”
clearance between shank and bottom of collet.
•
Always make sure the fence on your router
table is locked into position before each
use.
•
Always rout in two or more passes when
large amounts of stock must be removed.
•
Use reduced RPM speeds for large
diameter bits.
INSTALLING THE ROUTER
Place the crank handle into the hex hole in the lift’s
dial on the top plate. Crank the lift carriage up so that
it just contacts the O-rings at the top of the carriage
shafts. The carriage should be all the way toward
the top plate

shoulder bolts from one of the clamping blocks
and slide the clamping block on the carriage (Figure

Before installing the router motor, prop the unit up
on blocks of wood (Fig. 1) so the router’s collet can
extend through the center hole in the top plate.
The motor housing must be able to slide all the
way through and contact the inside back of the
center hole on the plate.
2. Locate your router on the chart below.
3. Align the letter and number associated with
your router (Figures 3 and Figure 4) and reinsert

Note: If installing in an INCRA router table, do not
use the set screws described below. Instead, use the
threaded holes for access to the pre-installed plate
leveler screws built into the router table.
The INCRA Special Edition model also includes the
top mounted CamLOCK plate locking system. See
included addendum for instructions.
Note: The INCRA Special Edition Mast-R-Lift™ II
incorporates INCRA’s 5 Piece MagnaLOCK Ring
Insert System. See included addendum for detailed
instructions.
MAGNALOCK RING INSERT SYSTEM
A JessEm router lift is similar to using a router mounting
plate. Your table top must have a recess machined into
the top. INCRA offers router table tops with pre-machined
recesses for all JessEm router lifts. If you are installing
this Lift in a custom table application you will have to
fabricate this opening yourself. INCRA offers a separate
template for this operation.
With the Mast-R-Lift™ II in the table top opening,
install (10) set screws into the holes around the
lift perimeter. Adjust the four corners rst (Figure 8) to
align the lift surface to the table surface so that both are
ush. Adjust the remaining set screws on the sides to
provide added support.
LEVELING THE LEFT IN THE TABLE TOP
1. Turn the Lift upside down on a table with the
threaded height adjustment rod facing yo
u.
2. Remove the ¼-20 x 1” Cap Screws from
the Carriage Nut Cover (Figure 11) an
d
remove the cover and o-ring (Figure 12)
Figure 12
3. Slide the carriage all the way up to the
towards the top plate.

USING YOUR MAST-R-LIFT™ II
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 2 mm, 1/2 revolution = 1 mm of
change and 1/4 revolution = 1/2 mm 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.
With the Mast-R-Lift™ II you have the added benefit
of locking your Lift in a desired position for long
term routing operations and having the comfort in
knowing the position you have set is locked in
place.

LIFT™ II
RE-ADJUSTING THE THREAD TENSION
All JessEm Lifts feature our patented thread tensioning
design. Thread tension is se
t at the factory and
depending on
the amount of use you may have to reset
this adjustment periodically, depending on the amount of
tension you desire.
If the bit height ever begins to change (or drop) during
use, the thread tensioning likely needs to be reset.
