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.

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 2

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..
