• If you do not have a manual, contact the
manufacturer and obtain one before using any
power tool.
• Always wear eye protection in compliance with ANSI
safety standards when operating any power tool.

IMPORTANT SAFETY PRECAUTIONS CONT’D
.
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

ROUTER CHART
1. With a 1/8” hex key, remove one of the ¼”
shoulder bolts from one of the clamping blocks
and slide the clamping block on the carriage (Figure
2)
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
and tighten the ¼- x 1-1/2” Shoulder Bolt you
removed in step 2.
4. Repeat this for all four carriage clamping blocks
• Do not wear loose clothing or jewelry tha
t
may catch on tools or equipment.
• Unplug the tool or machine when mounting
or making any adjustments to mechanical
performance
DO NOT USE A CORDLESS DRILL TO
RAISE AND LOWER THE LIFT
CARRIAGE. THE AMOUNT OF
FRICTION WILL CAUSE PREMATURE
WEAR OF THE THREADS AND WILL
VOID WARRANTY

tensioning cap screw sufficiently to force the
carriage to spread (Figure 5). This allows the
router to be installed easily.

6. Now slide the router motor into the carriage so
the top of the motor housing just makes contact
with the inside surface of the center hole in the
top plate (Figure 6)

8. With the Mast-R-Lift™ II Crank handle, re-tighten
the tensioning cap screw. (Figure 7)

7. Rotate the router so that when the final
installation is made all router controls will be
positioned for convenient access an there is no
interference. Then back the motor off approx.
1/16” from contacting the top plate and tighten
the cap screw on the carriage assembly.

the Lift’s top plate (Fig. 5).
2. With the insert wrench provided, insert the
prongs of the wrench into the
corresponding holes in the insert ring and
turn the insert ring counter clockwise to
tighten.
Turn the insert wrench clockwise to loosen and
remove the ring. If the insert ring becomes too tight
to loosen with hand pressure, a tap clockwise on the
insert wrench with a block of wood will loosen it.
INSTALLING A JESSEM LIFT IN A CUSTOM
ROUTER TABLE APPLICATION
A JessEm router lift is similar to us i ng a router mounting
plate. Your table top must h a ve a port machined into the
top. JessEm offers so l id phenolic router tables tops with
pre-machined p orts for all JessEm router lifts. If you are
inst a lling this Lift in a custom table application you will
have to fabricate this opening yourself. Jes s Em offers a
separate template for this operation. See your JessEm
distributor for the proper templa t e for your JessEm
Mast-R-Lift II.
ADJUSTING THE FIT IN THE TABLE PORT
Your Mast-R-Lift™ II comes with adjustable snugger
bars to allow for a tight fit in the table top
opening and eliminate any movement of the
plate. Use the 3/16” hex key provided to loosen
the cap screws on the snugger bars. Move the bars
out slightly and check for fit. Adjust again if
necessary. (Figure 9)
Figure 10
Figure 8
LEVELINGTHE LIFT IN THE TABLE TOP
1. With the Mast-R-Lift™ II in the table top opening,
install (10) set screws into the holes around the
lift perimeter. Adjust
(Figure 8) the four corners first to align the lift
surface to the table surface so that both are flush.
Adjust the remaining set screws on the sides to
provide added support.
TAB-LOC PHENOLIC INSERT RINGS
Your Mast-R-Lift™ II comes with one 2” insert ring with
a pre-drilled center hole. Additional ring sets are
available with different diameter pre-drilled holes
and/or no pre-drilled holes for creating your own
custom center hole diameters. See your JessEm
distributor for these and other accessories
The Mast-R-Lift II is manufactured to precise tolerances.
Due to the manufacturing tolerances of the different
router motors that the Mast-R-Lift II will accommodate,
you may find that your Lift is not as smooth as it should
be after the router is installed. To correct this, first: raise
the Lift carriage with the router installed to a position
close to the top plate. Then, loosen the two 5/16- 18
socket screws holding each shaft onto the top plate a
quarter of a turn and re-tighten. This relieves any stress
on the shafts to center themselves with respect to the
carriage after the router is installed ensuring there is no
resistance in the movement of the carriage up and down.

1. Turn the Lift upside down on a table with the
threaded height adjustment rod facing you.
2. Remove the ¼-20 x 1” Cap Screws from
the Carriage Nut Cover (Figure 11) and
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, turnthehandle counter-
clockwise. Keepin mind thatone 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 havingthe comfort in
knowing the position you have set is locked in
place.

RE-ADJUSTING THE THREAD TENSION
All JessEm Lifts feature our patented thread tensioning
design. Thread tension is set 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.
