GENERAL SAFETY INSTRUCTIONS
Know your power tool – Read the owner’s manual carefully. Learn the applications and
limitations of your sander as well as the potential hazards this particular tool presents.
Ground all tools – Check the receptacles in your shop. They should all be approved
3-prong grounding type. If they are not, a qualified electrician should install grounded
receptacles throughout your shop. Any tool that has a three-pronged plug should be
connected to a grounded receptacle. Double insulated tools do not require this type plug,
however, only a small proportion of the tools manufactured today are double insulated.
Protect yourself – Use full face shield or approved safety glasses with side shields.
Everyday eyeglasses should not be used as safety glasses. Use dust mask when sanding.
Wear safety approved hearing protectors. Extended exposure to noise from power tools
can damage your hearing.
Never operate power equipment if you are fatigued, taking medication or drinking
alcohol.
Keep all machine guards in place and in working order.
Remove adjusting keys and wrenches – Any time you attach accessories, change belts
or make adjustments to any tool, make sure that all keys, adjusting wrenches and other
tools are removed from the machine before turning it on.
Keep your shop clean, well lot, and dry. Clutter invites accidents. You can make your
shop time more comfortable with proper lighting – eye strain fatigues your entire
body. Particular attention should be paid to moisture. Using power tools in damp or wet
locations can result in electrocution.
Keep children away – All visitors should be kept at a safe distance from work area and
should wear eye and ear protection.
Maker workshop childproof – Use padlocks, master switches, or any system that
prevents children or other unauthorized persons from starting machinery.
Use the right tool at the recommended rate – Don’t force tools or attachments to do a
job for which they were not designed. Learn the recommended rate of use for each tool.

Wear proper apparel –Do not wear loose clothing, gloves, neckties, rings, bracelets,
wrist watches or other jewelry which can get caught in moving parts. Roll your sleeves
above the elbows. Wear comfortable, non-slip shoes. Tie back or net long hair.
Secure work – Use clamps, dogs or a vise to hold work when practical. You’ll have more
control if both hands are free to operate the tool. Keep proper footing and balance at all
times.
Maintain your tools – Safety and quality of work are improved when you keep your
tools clean. Follow lubrication schedules for all tools and accessories.
Disconnect tools – Never rely on the switch when changing or cleaning belts or making
adjustments. Always unplug any machine before servicing or changing belts.
Beware of unintentional start-ups – Check the switch before connecting any machine
to the power source – be sure it is in the “Off” position.
Do not use machines as step stools or ladders – Serious injury could result if the
machine tips over.
Check damaged parts – Repair or replace any part that becomes damaged or worn
before using the tool again. Any time a repair or adjustment is made, check alignment
of all moving parts, breakage of parts, mounting and all conditions that may affect its
operation.
Always turn tool off before leaving it – until tool comes to a complete stop.

SAFETY INSTRUCTIONS FOR YOUR WOODMASTER SANDER
1. Always disconnect power supply before removing the cover from your sander or
before making any adjustments.
2. Always replace cover before connecting sander to power supply.
3. Keep hands and fingers at least 12” from the front, rear and sides of your sander while
in operation.
4. Never reach under the cover while sander is in operation.
5. Form a habit of looking for tools, wrenches, rulers, etc., before replacing the cover
and connecting the power supply.
6. Before starting the sander, check its stability --is it resting firmly on the floor?
7. Before starting sander, always check condition of sanding belt.
8. As you face the infeed table of the sander, all controls are on the left. Stand to that
side of the machine while operating – never directly in front of or behind the board
being fed through the machine. You’ll have best control of the workpiece from this
side, and ready access to the switch should a problem develop.
9. Learn the capabilities of your machine (outlined in the specifications) and never
exceed these.
10. Before starting the sander, check to see that there is sufficient clearance on both the
infeed and out feed sides of the machine for the stock to be sanded.
11. Never feed two boards of different thickness at the same time. The thicker board
will raise the spring-loaded feed rollers allowing the thinner board to slip beneath
them without being properly held down. This can cause the thinner board to be
thrown through the machine when it contacts the spinning drum.
12. Never feed boards one after another of different thickness without adjusting the
sander. The feed rollers will not properly hold the thinner board and kick-outs leave
the machine at high speed.
13. Keep stock parallel with the sides of the sander as it is fed through the machine.

14. Never attempt to clear dust from the sander while it is running – turn the
machine off, disconnect the power supply and allow the drum to come to a complete
stop before reaching under the infeed or out feed sides of the machine.
15. Support long or heavy stock with roller stands.
16. Carefully check all stock for nails, screws, imbedded bullets, loose knots, or any
other foreign object that may contact the drum. Failure to do this may result in
damage to the drum.
17. While your sander is plugged in --even when it is switched off – it is surrounded by
a Danger Zone. This zone extends away from the infeed and outfeed openings as
shown in Illustration.
Exposure of your hands, fingers and body to the Danger Zone should be kept to an
absolute minimum.
WARNING
Never stand directly in front of or behind the sander while feeding stock. Always
stand to the left of the machine out of the Danger Zone holding the stock by the
edges as shown in Illustration.

POWER SUPPLY
Your sander is powered by a 2HP motor which requires a 25 amp, 220 volt circuit. All
wiring should be done by a licensed electrician.
Do not use extension cords for the motor. Line loss from extension cords can cause
poor performance and damage
REMOVAL OF SANDING DUST AND DEBRIS
Woodmaster recommends the use of some form of dust collection system while
operating your sander. Dust poses both a fire hazard and a safety hazard. Piles of dust
can hide power cords, lumber, tools, etc. that might cause you to trip. Also, the fine dust
produced by sanding may cause breathing discomfort and” other respiratory problems.
You will find that your sander operates more efficiently when dust is removed before
it accumulates and “cakes” on the feed rollers.
Even when using a dust collection system, you should provide adequate ventilation
in your shop while operating your sander and wear a dust mask around your mouth and
nose.
SHOP TIP – In certain applications, where an extremely large volume of dust is created,
directing a jet of air from an air compressor at the lower part of the drum on the outfeed
side is helpful. This will create turbulence and kick up the dust before it can cake or
clump and allow it to be drawn upwards into the dust collection system.
INSTALLING THE MAIN DRIVE MOTOR
The motor mount on your sander is designed to maintain optimum alignment and belt
tension once it is installed. Care should be taken to obtain proper alignment. This will
increase belt life and deliver maximum power to the drum.
Loosen the bolts that attach the motor mount rails (these run from front to back of
sander) to the crossbars.
Place the motor on the rails, insert a 5/16” carriage head bolt in each hole on the
motor mount so that the head of the bolt in each hole on the motor mount so that the head
of the bolt is toward the floor and place a flat washer, lock washer and nut on the bolt
Tighten nut finger tight.

Next, attach a belt to the drumhead pulley and position the motor so that the motor
pulley is directly underneath the drumhead pulley.
Once the motor mount rails are positioned so that the pulleys are aligned, square them
to the crossbars using a combination square (see Illustration).
Tighten the bolts that attach the motor mount rails to the crossbars. Now, slide the
motor toward the outfeed side of the sander until the belt will deflect about 1/2” under
light finger pressure. (For smooth performance and longer bearing life, it is better to have
the belt too loose than too tight.) Next, tighten the bolts that attach the motor to the rails.
ATTACHING THE DRUMHEAD MOTOR SWITCH
Make sure that the drumhead motor is unplugged and the switch is in the OFF
position.
Remove the two screws that hold the aluminum faceplate to the front of the switch.
Insert the box from inside the base. Now, from the outside of the base, replace the two
screws (see Illustration).

OPERATING INSTRUCTIONS
Now that you have assembled your sander, please take a moment to review the safety
instructions outlined in previous sections of this manual.
INDEXING YOUR SANDER
WARNING
Failure to follow this procedure for indexing may result in kickout of the
workpiece.
With the motor off, rest a practice piece of stock on the bed and turn the depth adjustment
crank until the feed rollers just touch the stock. Remove the stock from the machine,
turn the depth adjustment crank 2 1/2 turns clockwise (this procedure sets the depth of
the machine where the stock will feed without kickout, but still below the point where
sanding would occur).
Feed the stock into the machine keeping it parallel with the sides of the sander. Turn
the depth adjustment crank clockwise until the abrasive just contacts the stock (about 4
revolutions).
To make a sanding pass, determine the depth of sanding you want and turn the crank
the appropriate amount. In most cases, 1/4 to 1/2 turn of the crank will be sufficient.
SHOP TIP – You will achieve a better surface by making several passes at the same
setting instead of turning the crank between each pass.
SHOP TIP –If you are working with stock of varying thicknesses, work the thicker
boards down to the thinner ones before running all boards at a single setting.
SHOP TIP –You may find that a hardwood or formica insert bolted to the steel bed
will improve feeding with certain types of stock.
