You are now the proud owner of a
Lewis Multi-Drill DH3-W
Whether you have the DH3-WD Direct Drive or the
Universal Drive version –this Lewis Multi-
Drill Owner’s Manual deals with both
models.
We welcome and very much appreciate any
photos, movies and comments you care to send us
in regards to your Lewis Multi-Drill or any
other Lewis Product.
Also, please don’t hesitate to contact us if you have
any questions about the assembly or operation of
your Lewis power tools and equipment.
Congratulations!
Choosing the right Chainsaw
The size of your chainsaw is important!
Using a chainsaw with minimum 3 horsepower
(48 cc’s, 18”+ bar w/ 3/8” chain) is best, because it
ensures a commercial-grade clutch that although it
may sometimes slip under a heavy load, the clutch will not burn up.
Maximum chainsaw size is 100cc’s or 7 horsepower. Electric chainsaws and smaller
gas chainsaws will give satisfactory performances with lighter loads only.
If you have purchased a model DH3-WD Direct Drive version, then your saw
must have an accessible outboard sprocket. Most modern saws are built this way. If you
have purchased a model DH3-WU Universal Drive version, then you can mount your
Lewis Multi-Drill on any chainsaw.
Chainsaws must be properly maintained and serviced (see your chainsaw owner’s
manual or check with your local chainsaw dealer). Please ensure that your chainsaw’s
throttle and clutch are in proper working order –because they directly affect the safe
performance of the Lewis Multi-Drill.
The operator assumes all risk when using an engine with more than
100cc’s or 7 horse power.

Operating Tips
TIP #1 -Never let your Lewis Multi-Drill
gearbox run dry!!!
Nearly all gear damage occurs in a DRY
GEAR BOX.
Any oil or grease is better than none at all.
The gear box was filled at the factory with 10
ounces of 80/90 weight gear oil. To check oil
level, turn gearbox on its side as shown in
photo. Remove oil fill plug and then slightly tip
gearbox towards you, oil should start to drip
out if oil level is correct.
TIP #2 - Keep all nuts and bolts tight. Use Loctite to insure that
bolts don’t vibrate loose.
TIP #3 - In case of a jam: Stop the engine.
If the drill is jammed, you could damage your Lewis Multi-
Drill or your chainsaw if you continue to power up the saw. Just
stop the engine and free the drill or auger, then restart the engine
and resume drilling. Damage is more likely to occur with larger
chainsaw engines.
TIP #4 –Noise Levels: The sound level produced by a Lewis
Multi-Drill is negligible. Nearly all noise and vibrations
emanate from the drive engine. To determine relevant engine
noise and vibration levels, see your chainsaw owner’s manual.
Note that in certain applications, the Lewis Multi-Drill may
dampen the engine noise and/or vibration levels.
TIP #5 –Be Safe! Wear gloves, eye and ear protection and do
not operate this unit while under the influence of alcohol or drugs.
This Lewis Multi-Drill Owners Manual is general in
nature. If you have any questions or concerns, please check with
your local Lewis Multi-Drill dealer or call our factory for
more information. Do not take chances with your safety!!!

Assembly & Mounting Instructions
STEP 1
for DH3-WD Direct Drive
1.Remove bar and chain from your chainsaw,
retain bar-mounting nuts.
2. Remove the spring clip from your saw’s output shaft, then remove
the large washer and drive sprocket. Re-install spring clip but not
large washer or sprocket.
3. Assemble Direct Drive System: In the supplied plastic
tube find the correct 3/8” thick disk to fit the spline on the
output shaft of your saw. Then find the ½” thick master disk.
Line up the holes and bolt the two halves together using the
supplied screws. TIP: Use Loctite to insure screws stay
tight. In some cases the supplied L906A spacer is required to
lengthen the adaptor. If needed this spacer should be
sandwiched between the 3/8” disk for your saw and the
½” master disk. Use the three longer screws.
4. Bolt supplied mounting plate onto your saw using the
bar-mounting nuts that you retained.
5. Slide assembled Direct Drive onto Lewis Multi-Drill input shaft
(3/8” master disk side fits multi-drill). Attach
assembled Multi-Drill to mounting plate using the
supplied nuts and washers. Use Loctite. Insure adaptor
assembly slides over spline on saw, use saw’s chain
adjuster screw to insure adaptor remains in-line.
6. When the Lewis Multi-Drill is bolted tight to the saw, the adaptor
should have approximately ¼” of “back and forth” play. This allows everything to
float properly. If you have more than ½’ of play you may want to use the supplied
spacer to insure proper contact with the splines.

STEP 1 Alternate
for DH3-WU Universal Drive
1.Remove bar and chain from your
chainsaw, retain bar-mounting nuts.
2. Bolt supplied Universal Bar onto your
Multi-Drill using the supplied lock
washers, flat washers and nuts.
3. Bolt the Mini-Bar assembly on your chainsaw
using the retained bar-mounting nuts. Adjust mini-
bar back using the chain adjuster if your saw is so
equipped or just slide the mini-bar towards saw
handle and temporarily snug bolts.
4. Wrap supplied cutter-less chain around
the sprocket on the chainsaw and then around
the sprocket on the Multi-Drill and
fasten with supplied connecting link. Then
replace side cover on chainsaw, adjust chain
tension using the adjuster screw, and
permanently tighten mounting bolts. If the
cutter-less chain is too long, then grind off
rivets to remove links as necessary.
5. Slide supplied chain guard over Lewis
Multi-Drill studs and secure with 2 flat
washers and nuts, as well as 1 bolt and washer on
round end.
6. Bend brace to suit and attach with included nuts
and bolts for added support. See Item 31 on Page 8.

Assembly & Mounting Instructions
STEP 2
for DH3-WD Direct Drive and
for DH3-WU Universal Drive
1. Install handle: Remove the three 3/8”
bolts from the top of the Lewis Multi-
Drill. Keep unit upright as oil will leak
out. Position handle where desired and
replace bolts. Use Teflon tape or liquid
thread sealer to reseal the bolts.
2. Screw the supplied 1” Drive Adaptor into the
output shaft of the Lewis Multi-Drill until threads
are almost tight. Then line up the flat spots with those on the
Multi-Drill.
3. Slide the supplied Drive
Sleeve over the two flat spots and tighten set screw
(use Loctite). Failure to use the Drive Sleeve
may result in the Drive Adaptor threads
becoming extremely tight and difficult
to remove.
You are now ready to attach your auger or drill and get to work or go play!
Step 3
Attach your auger to the Lewis Multi-Drill
All Lewis Augers come with a “no tools required”
swivel pin that is easy to install or remove even with gloves
on. Simply pop the retainer spring off the end of the retainer
pin and remove from auger, line the pin hole of the Lewis
Multi-Drill with the one in the auger, then replace the
retainer pin and stretch the retainer spring back into place..
