DUST COLLECTION SYSTEM. Never operate the
sander without an adequate dust collection
system in place and running.
REPLACING SANDING PAPER. Replace sanding
paper when it becomes worn.
EXPERIENCING DIFFICULTIES. Any problem, with
the exception of conveyor belt tracking that
is concerned with any moving parts or accessories, must be investigated and corrected
with the power disconnected, and after all
moving parts have come to a complete stop.
MAINTENANCE AND ADJUSTMENTS. Never
attempt to adjust conveyor belt tracking when the sanding drums are engaged.
Perform machine inspections and maintenance service promptly when called for.
Disconnect power before performing maintenance or adjustments on the sander.
RESPIRATOR AND SAFETY GLASSES. Always wear
a respirator and safety glasses while operating the machine. Dust and chips are created
when sanding. Some debris will be ejected,
becoming hazards to the eyes and lungs.

safe to operate. DO NOT connect this machine to the
power source until instructed to do so in the "Power
Connection" portion of this manual.
W1772 Single-Phase 240V
ELECTRICAL
Operation
The Model W1772 is wired for 240V single-phase operation.
This machine must be hardwired to a locking shutoff
switch (Figure 2) by a qualified electrician. Since hardwir-
ing involves a permanent installation with conduit runs,
this task can only be safely accomplished by a qualified
electrician. As always, observe all applicable electrical
codes when connecting this machine to power.
This machine must be grounded! Verify the ground before
connecting this machine to the power source.

3-Phase Operation
The Model W1773 is prewired for 240V 3-phase operation,
but may be rewired for 480V 3-phase operation (see Page
13).
This machine must be hardwired to a locking shutoff

switch by a qualified electrician. Hardwiring involves a
permanent installation with conduit runs that can only be
accomplished safely by a qualified electrician. As always,
observe all applicable electrical codes when connecting
this machine to power.
This machine must be grounded! Verify the ground before
connecting this machine to the power source.
Phase Converter
The power from the manufactured power leg (wild wire)
of a phase converter fluctuates, which may damage electrical components if connected to the wrong incoming
power terminal. If you must use a phase converter for
3-phase power, only connect the "wild wire" to the L1
terminal. The wire from the L1 terminal can handle some
fluctuation because it goes directly to the motor. The
power going to the L2 and L3 terminals connects to the
controls and must be consistent to prevent damage.
Figure 3. Locking shutoff switch.
Attempting to connect this machine to
the power source without a qualified
electrician greatly increases the risk
of electrocution, fire, or machine
damage.

Machine Placement
• Floor Load: This machine distributes a heavy load in
a small footprint. Some residential floors may require
additional bracing to support both machine and
operator.
• Working Clearances: Consider existing and
anticipated needs, size of material to be processed
through the machine, and space for auxiliary stands,
work tables or other machinery when establishing
a location for your drum sander (see Figure 13 for
minimum working clearances).
• Lighting: Lighting should be bright enough to
eliminate shadow and prevent eye strain.
• Electrical: Electrical circuits must be dedicated or
large enough to handle amperage requirements.
Follow local electrical codes for proper installation of
new lighting, outlets, or circuits.
The Model W1772/W1773
is an extremely heavy
machine. Serious personal injury may occur if
safe moving methods are
not followed. To be safe,
you will need assistance
and power equipment
when moving the shipping crate and removing
the machine from the
crate.
Use lifting straps with a combined
minimum of 2000 lbs. lifting capacity.
If lifting straps break, serious personal
injury may occur.
SET UP
MAKE your shop “child safe.” Ensure
that your workplace is inaccessible
to youngsters by closing and locking
all entrances when you are away.
NEVER allow untrained visitors in
your shop when assembling, adjusting or operating equipment.

Lifting Sander
To place the sander in a permanent location, do these
steps.
1. Unbolt the sander from the pallet.
2. Position the forklift forks directly above the sander.
Place two lifting straps with hooks on the ends over
the forklift forks and slide the hooks into the eyebolts shown in Figure 14.
3. Lift the sander and move it to your predetermined
location. DO NOT lift it any higher than is necessary
to clear the floor.
Mounting to Shop Floor
Although not required, we recommend that you mount
your new machine to the floor. Because this is an optional
step and floor materials may vary, floor mounting hardware is not included.

Anchor Stud
Bolting to Concrete Floors
Lag shield anchors with 3/8" lag bolts or anchor studs
(Figure 15) are two popular methods for anchoring an
object to a concrete floor. We suggest you research the
many options and methods for mounting your machine
and choose the best that fits your specific application.
NOTICE
Anchor studs are stronger and more permanent alternatives to lag shield anchors; however, they will stick
out of the floor, which may cause a tripping hazard if
you decide to move your machine at a later point.
Bolting to Wood Floors
The most secure method of mounting this drum sander to
a wood floor is using
securing the bolts from under the floor with flat washers,
lock washers and hex nuts, as shown in Figure 16. Use lag
bolts with washers only if you do not have access to the
underside of the floor.

Dust Collection
Recommended CFM at Sander: ................. 1600 CFM
Do not confuse this CFM recommendation with the rating
of the dust collector. To determine the CFM at the dust
port, you must take into account many variables, including the CFM rating of the dust collector, the length of
hose between the dust collector and the machine, the
amount of branches or Y's, and the amount of other open
lines throughout the system. Explaining this calculation
is beyond the scope of this manual. If you are unsure of
your system, consult an expert or purchase a good dust
collection "how-to" book.
We recommend using a dust collection system that produces a minimum of 2000 CFM. A fine layer of dust will
be present on your stock as it comes out of the sander.
This is normal.
Figure 17. Dust port locations.
To connect the dust ports to a dust collector, do these
steps:
1. Attach 4" dust collection hoses to the dust ports
shown in Figure 17 and secure them with hose
clamps.
Power Connection
Before connecting to power, read through the
ELECTRICAL section on Page 11 to check that your
setup follows the safety and circuit requirements for this
machine. Be sure to also have your electrician on hand
for the "Test Run" in case the power is connected out of
phase (Model W1773 only).
To connect the sander to the power source:
1. Remove cover from the power connection junction
box on the rear of the frame.
SET UP
Attempting to connect this machine to
the power source without a qualified
electrician greatly increases the risk
of electrocution, fire, or machine
damage.

2. Feed the power wires through a strain relief on the
bottom of the junction box, tighten the strain relief,
connect the cord to the terminals shown in Figure
18 or 19, and re-install the junction box cover.
Note (Model W1773 Only): When using a phase
converter, connect the manufactured power leg or
"wild wire" to the L2 terminal (Figure 19). The L2
terminal can handle power fluctuation because it is
wired directly to the motor. The other wires connect to the controls and must have consistent power
to prevent damage.
3. Shut off the main power at the power source circuit
breaker, and attach the wires to the locking shutoff
switch to complete the power connection.
