sander. Before unpacking or using the machine, familiarizeyourselfwithitscomponents,features, and
basicadjustmentsbyreviewingthefollowing pages. You will find it an invaluable aid in setting up,
operating, and servicing your machine.
CAUTION, SAFETY FIRST
When maintaining and operating this machine, always put safety first. For your own safety, read and
understandthisowner’s manualbeforeoperatingthismachine.Alwaysheedandfollowallnor- mal
safetyprecautions,includingthefollowing:
SAFETY RULES
1. KEEP GUARDS IN PLACE and in working order.
2. REMOVE ADJUSTING KEYS AND WRENCHES. Form habit of checking to see that keys and
adjusting wrenches are removed from tool before turning it on.
3. KEEP WORK AREA CLEAN. Cluttered areas and benches invite accidents.
4. DON'T USE IN DANGEROUS ENVIRONMENT. Don't use power tools in damp or wet locations, or
expose them to rain. Keep work area well lighted.
5. KEEP CHILDREN AWAY. All visitors should be kept safe distance from work area.
6. MAKE WORKSHOP KID PROOF with padlocks, master switches, or by removing starter keys.
7. DON'T FORCE TOOL. It will do the job better and safer at the rate for which it was designed.
8. USE RIGHT TOOL. Don't force tool or attachment to do a job for which it was not designed.
9. USE PROPER EXTENSION CORD. Make sure your extension cord is in good condition. When
using an extension cord, be sure to use one heavy enough to carry the current your product will
draw. An undersized cord will cause a drop in line voltage resulting in loss of power and
overheating. Table A shows the correct size to use depending on cord length and nameplate ampere
rating. If in doubt, use the next heavier gage. The smaller the gage number, the heavier the cord.

10. WEAR PROPER APPAREL Do not wear loose clothing, gloves, neckties, rings, bracelets, or other
jewelry which may get caught in moving parts. Nonslip footwear is recommended. Wear protective
hair covering to contain long hair.

11. ALWAYS USE SAFETY GLASSES. Also use face or dust mask if cutting operation is dusty.
Everyday eyeglasses only have impact resistant lenses, they are NOT safety glasses.
12. SECURE WORK. Use clamps or a vise to hold work when practical. It's safer than using your
hand and it frees both hands to operate tool.
13. DON'T OVERREACH. Keep proper footing and balance at all times.
14. MAINTAIN TOOLS WITH CARE. Keep tools sharp and clean for best and safest
performance. Follow instructions for lubricating and changing accessories.
15. DISCONNECT TOOLS before servicing; when changing accessories, such as blades, bits, cutters,
and the like.
16. REDUCE THE RISK OF UNINTENTIONAL STATING. Make sure switch is in off position
before plugging in.
17. USE RECOMMENDED ACCESSORIES. Consult the owner's manual for recommended
accessories. The use of improper accessories may cause risk of injury to persons.
18. NEVER STAND ON TOOL Serious injury could occur if the tool is tipped or if the cutting tool is
unintentionally contacted.
19. CHECK DAMAGED PARTS. Before further use of the too., a guard or other part that is damaged
should be carefully checked to determine that it will operate properly and perform its intended
function - check for alignment of moving parts, binding of moving parts, breakage of parts,
mounting, and any other conditions that may affect its operation. A guard or other part that is
damaged should be properly repaired or replaced.
20. DIRECTION OF FEED. Feed work into a blade or cutter against the direction of rotation of the blade
or cutter only.
21. NEVER LEAVE TOOL RUNNING UNATTENDED. TURN POWER OFF. Don't leave tool until
it comes to a complete stop.

Note: The Intellisand™Control (Fig. 5) reduces
the chance of potential damage from many
overload situations. Theconveyormotorfor
feedingstockisinfinitely variable from 0-15
ft/min. If the load on the drum motor reaches its
upper limit, the Intellisand Controlwill
automaticallyslowthefeedrateofthe conveyor.
Whenthe load isdecreased on the main motor,the
feedratewillautomaticallyincreasebut never
exceed the manual setting on the dial.
CONNECTING DUST COLLECTORS
Dust collection is necessary for all models.The
SUPERMAX 37x2 model is equipped with three
4" dust exhaustports.
To attach the sanderto your collection sys-
tem,install4"hosefromyourcollector.(SeeTips
ForMaximum Performance). The minimum
recommended dust collector capacities at the
dust ports are:25x2:600 CFM. Forbestresults,
followthe recommendations ofthe manufacturer
of your dust collection equipment.
CHECKING DRUM ALIGNMENT
The sander was shipped from the factory
preadjusted with the drum(s) aligned to the con-
veyortable.Unlessthemachinewasstresseddur-
ing shipment, only fine adjustment should be nec-
essary. Minor alignment corrections can be done
without relieving V-belt tension or adjusting the
tension rollers, but should be done without any
abrasive strips attached.
