OPERATING A LANDIS SANDER
WARNING: Eye protection should always be worn by the operator and others in the
work area when the Sander is in use. Eye protection is required for
protection from flying debris and dust, which could cause eye injury.

INSTALLATION
The Landis Sander should be located on a flat, firm surface, in an area
free of obstructions that could interfere with the safe operation of the
equipment. The Sander should be positioned, leveled and the wheels on
a locked position.
WARNING: All electrical work must be performed by a qualified
electrician and must conform to all state and local
ordinances.
Do not, under any circumstance, tamper with, modify,
or adapt the electrical plug and cord provided with this
machine.
ELECTRICAL CONNECTIONS
Electrical connection may be made by either plugging the provided
electrical cord into an appropriately wired electrical socket, or by wiring
the machine directly into an electrical disconnect box.
WARNING: If the electrical cord, plug or wiring should become
frayed or damaged, replace it at once. Do not attempt
to operate the machine with faulty wiring as it could
result in severe injury or death.
NOTE: Refer to the machinery identification plate to determine
the electrical specifications of this machine in respect
to voltage, phase and amperage requirements.
WARNING: Do not start Sander before checking for proper sanding
belt tracking.

START-UP
WARNING: Eye protection should always be worn by the operator
and others in the work area when setting up the
machine. Eye protection is required for protection from
flying debris and dust, which could cause eye injury.
Before shipment, your Landis Sander was checked at the factory for
proper adjustment and operation. However, due to the possibility of
jarring or damage during handling and shipping, it is necessary to check
that the machine is in proper working order before use.
WARNING: Before initial start up, turn sanding shaft by hand to
ensure that all parts are free.
BEFORE CONNECTION TO AN ELECTRICAL POWER SUPPLY:
1. Check that the switch is off.
2. Rotate the sanding shaft to see that all parts are free and not
binding. You can tell that one complete revolution has been made
when the joint of the sanding belt has gone by the sanding wheels
twice.
3. If applicable, rotate the Naumkeag by hand to see that the
sanding pad is not damaged and the shaft not bent. Optional
accessory.
WARNING: As with any piece of electrical equipment, there is an
ever present hazard of electrical shock when operating
or touching the Sander. Ensure the machine is properly
grounded at all times.
Do not force the equipment. It will do the job better and
safer at the rate for which it was designed.

ACCESSORIES
WARNING: Eye protection should always be worn by the operator
and others in the work area when using the accessories
supplied with the Landis Sander. Eye protection is
required for protection from flying debris and dust,
which could cause eye injury.
To use interchangeable wheels on bayonet fitted shaft:
1. Remove bayonet from right side. This is done by firmly grasping the
wheel, and turning the right side wheel in a downward motion. This will
loosen the bayonet.
2. Installing new bayonet: Make sure you always lock the bayonet by
holding the left side of the shaft firmly and turn the bayonet in an
upwards motion.
MAINTENANCE
A properly maintained machine will give you years of satisfactory service,
whereas an abused machine will not. We strongly recommend that you
observe the following procedures for your own benefit and safety.

DAILY AND WEEKLY MAINTENANCE
1. Clean your Landis Sander daily.
2. Shake dust bag daily. Empty it weekly.
After cleaning the machine, turn dust extraction motor off. While
the motor is coasting to a stop, shake bag vigorously.
The cleaner you keep the dust bag, the less likely you are to burn a
hole in it. Failure to shake the dust bag and empty it will only
increase this likelihood, but also cause a significant loss of
dust extraction from the sanding, trimming and brushing
areas.
For better suction, gates have been installed
behind hoods. By opening and closing the
appropriate gates, suction can be controlled.
WARNING: Dust from Sander is combustible. Do not smoke while
cleaning the machine and dust collector.
Damaged dust bag will allow the escape of
combustible materials causing a fire hazard around the
machine.
Check damaged parts. Before further use of a tool,
guard or other part that is damaged, check carefully to
determine that it will operate properly and perform its
intended function. Check for mounting or any other
condition that may affect its operation. A tool, guard or
other part that is harmfully damaged should be properly
repaired or replaced.
If the electrical cord, plug or wiring should become
frayed or damaged, replace it at once.
Do not operate machine without hoods properly
installed.

After making adjustments, remove all wrenches and
other tools before operating the Sander.
Use extra caution when starting the Sander for the first
time after installing a new tool or part.
MONTHLY MAINTENANCE
1. Check the rubber sanding wheel surface for any accumulation of
dust. Clean if necessary. Replace the wheel if worn.
2. V-Belts –Check tension and adjust if necessary.
3. Check for proper opening and closing of all dust dampers,
removing and cleaning any accumulation around the openings.
LUBRICATION
Your Landis Sander is equipped with sealed bearings throughout, which
should be replaced if they ever wear out.
Other parts should not require any lubrication, only cleaning the parts is
required.
Lubrication will only attract dust and would be more harmful than helpful.
V-BELT ADJUSTMENT AND REMOVAL
The V-Belt on the Landis Sander should be checked monthly for proper
tension and general condition. Loose V-Belt will decrease the power
available to the various tools and lower the efficiency of your Sander.
If you discover a worn or frayed belt, replace it now so it won’t break at
an inconvenient time.
WARNING: Disconnect electrical power supply before working on
the machine.

9
TO CHECK V-BELT TENSION:
1. Disconnect the electrical power supply.
2. Check the tension of the V-belt running to the motor; it should
depress approximately ½” when pressed in the middle with
moderate force.
3. Rotate the V-belt by hand, visually inspecting the belt for damage.
4. If tensions or conditions are bad, adjust tension or replace V-belt.
WARNING: Do not over tighten V-belts, as to do so will cause rapid
belt wear and premature bearing failure.
After making adjustments, remove all wrenches and
other tools before operating the Sander.

wiring and can be hazardous. If you are not familiar
