SAFETY

General Rules

READ THE MANUAL: Always read the owner’s manual carefully before attempting to use the machine knows the limitation and hazards associated with its use.

INSTALLATION: If mounting machine to the floor, use high quality anchor bolts through the mounting holes on the base. If using a mobile base, be sure to lock the wheels.

PROTECTION: Take every precaution to protect yourself, others around you, and the machine itself, from imp- roper use. Safety is a combination of using common sense, knowing how to use the machine and being alert at all times when using the machine.

EYES: Always wear approved safety goggles, glasses, or a face shield when operating this machine. There are no exceptions to this rule.

DRESS CODE: Do not wear loose clothing, neckties, jewelry, or gloves that can get caught in moving parts. Confine long hair. Keep sleeves above the elbow.

PLACEMENT: Place machine so that potential kickback area is not in line with aisles, doorways, wash stations, or other work areas.

ELECTRICAL GROUNDING: Your machine must be electrically grounded. If a cord and plug are used, make certain the grounding lug connects to a suitable ground. Follow the grounding procedure indicated by National Electric Code. Keep power tools in dry areas free from moisture.

GUARDS: Be sure machine guards are in place and in good working order. Use them at all times on operations where they can be used. If a guard must be removed for any operation, make sure it is replaced immediately following completion of that operation.

POWER OFF: Make sure the machine is either unplugged or electrically disconnected and locked out when performing maintenance or service work.

HOUSEKEEPING: Before turning on machine, remove all extra equipment such as keys, wrenches, scrap, stock, and cleaning rags from the machine. Keep the area around machine clean and free of scrap material and sawdust to minimize the danger of slipping.

POWER ON: On machines equipped with a manual starter make sure the starter is in “OFF” position before connecting power to
machine.

Specific Rules

READ THE MANUAL: Read, understand, and follow the safety instructions found in this manual. Know the limitations and hazards in using the model 12″Jointer. Safety decals are placed on each machine as reminders of good safety practice.

NEVER: surface stock less than 12 inches long, or 3 inches wide, or 3 inches thick without a hold down push block.

3 INCH RULE: When working a piece of wood on the jointer, follow the 3 inch radius rule. The hands must never be closer than 3 inches to the cutterhead. Fig. 1

KICKBACK: Use extra care in the location of the jointer in the shop. Position the jointer so that a kicked back stock will strike a wall and not endanger other persons in the area.

AVOID TIP-IN: Never apply pressure to stock directly over the cutterhead. This may result in the stock tipping into the cutterhead along with the operator’s fingers. Follow the 3 inch rule. Position hands away from extreme ends of stock, and push through with a smooth, even motion.

AVOID KICKBACK: “Pull-out” and the danger of kicked back stock can occur when the work piece has knots, holes, or foreign materials such as nails. It can also occur when the stock is fed against the grain on the jointer. The grain must run in the same direction you are cutting.

Before attempting to joint. Or plane each work must be carefully examined for stock condition and grain orientation.

NOTE: At certain time it may be necessary to plane against the grain when working with swirl grain wood burls. With this type work the operator must use a lesser depth of cut and slow rate feed.

HAND SAFETY: It is good practice to move the hands in an alternate motion from back to front as the work continues through the cut. Never pass the hands directly over the cutter knife. As one hand approaches the knives remove it from the stock in an arc motion and place it back on the stock in a position beyond the cutter knife (Fig. 2).

NOTE: At all times hold the stock firmly.
IF YOU ARE NOT thoroughly familiar with the operation of jointers obtains advice from your supervisor, instructor or other qualified person.

DRUGS, ALCOHOL, MEDICATION: Do not operate tool while under the influence of drugs, alcohol, or any medication.

ADDITIONAL HEALTH HAZARDS: Some dust created by power sanding, sawing, grinding, drilling and other construction activity contains chemicals known to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:

• Lead from lead-based paint.
• Crystalline silica from bricks and cement and other masonry products.
• Arsenic chromium from chemically-treated lumber.

YOUR risk from these exposures varies, depending on how often you do this type of work .Reduce your exposure to these chemicals. Work in a well-ventilated area, and work with approved safety equipment, such as those dust masks that are specifically designed to filter out microscopic particles. Use wood dust collection systems whenever possible.

RECEIVING THE JOINTER

Carefully unpack the jointer and all loose items from the wood crate and inspect for damage. Any damage should be reported to your distributor and shipping agent immediately. Before proceeding further, read your manual thoroughly to familiarize yourself with proper assembly, set-up, maintenance, safety and operating procedure.

Exposed metal parts such as the table and fence have been given a protective coating at the factory. This should be removed with a soft cloth moistened with a solvent (such as kerosene). DO NOT use acetone, gasoline or lacquer thinner this purpose. After cleaning, we recommend you cover all unpainted surface with a good quality paste wax.

INSTALLATION & ASSEMBLY

Tools required:
Provided: 14 mm wrench, 10mm Allen head wrench
Not provided: knife setting gauge, 1/2″wrench

FENCE INSTALLATION

Mount the fence to the holes on the jointer table with the provided Allen head wrench, Fig. 3. Tighten the cap screw securely.

DRIVE BELT ADJUSTMENT

Remove the three (3) crown nuts and washers on the belt guard with the 14mm wrench, and remove guard, Fig. 4. Use a 1/2″wrench to adjust the screws and nuts in the motor support. Using the adjusting slots on the motor support to raise or lower motor support to obtain proper tension.

ELECTRICAL CONNECTION

IMPORTANT: Make sure the electrical characteristics are the same between the motor nameplate and the power source, and make sure the circuit on which the jointer will be used is properly fused and that the wire size is correct.

WARNING: THE MACHINE MUST BE PROPERLY GROUNDED TO HELP AVOID ELECTRIC SHOCK AND POSSIBLE DEATH.

1. Connect wires both to electric connection box and power source (see electrical schematic, page20). The green wire (ground) must be properly grounded.
2. After wiring is complete, turn the drive motor on momentarily to check for proper direction of rotation. If the rotation is in the wrong direction, reverse the motor rotation according to the instructions furnished with motor.

CAUTION: IF THE ELECTRICAL INSTRUCTION ARE NOT COMPLETELY UNDERSTOOD, OR IF YOU AREIN DOUBT AS TO WHETHER THE MACHINE IS PROPERLY GROUNDED, CHECK WITH A QUALIFIED ELECTRICIAN OR SERVICE PERSON BEFOREPROCEEDING.

ADJUSTMENTS

REPLACING KNIVES

After a period of use, the dull knives should be replaced or reground. To remove the knife (A), release the six (6) gib screws (B) and gib (C) and springs (D) from the holes of cutterhead, Fig. 5. To install the knives, insert the springs and put the knife and gib inplace. Before tightening the knives into cutterhead, they must first be carefully reset. Refer to “Setting Knives &Outfeed Table.

SETTING KNIVES & OUTFEED TABLE

For accurate work in most jointing operations, the outfeed table must be exactly level with the knives at their highest point of revolution this means, of course that the knives must be parallel to the table and project equally from the cutterhead.
To properly set the knives and align them with the outfeed table, proceed as follows:

1. Disconnect jointer from power source.

2. Loosen the lock handle (A) and raise table adjustment arm (B), Fig. 6, on the outfeed table so that the screw (C) is just against the outfeed table.
   

3. Place one knife in its groove so that the bevel is 1/16″from the surface of the cutterhead.

4. Slip knife gib into place and lightly tighten gib locking screws.

5. A knife-setting bar or steel straight edge can now be used to set the knives. However, for more precise adjustment, a Quick-Set Knife Gauge is recommended. Place the gauge on the outfeed table and “0” the indicator as shown in Fig. 7a.

6. Lift the model 150 gauge off the outfeed table to see how far below the bottom of the gauge the indicator travels. The indicator should read between .025 and .050 as shown in Fig. 7b. If the indicator reads outside of this range, loosen the setscrew in the side of the gauge and adjust the indicator so that it will read within the range above. Zero the indicator as shown in Fig. 7a.

7. Repeat this process until indicator reads within the .025 to .050 range. Always zero the indicator (as shown Fig. 7a) before each use. Now place it on the outfeed table to the rear of the cutterhead with the flat indicator point over the cutterhead, Fig. 7c.

8. Adjust the blade within the cutterhead. Watch the pointer on the Model 150 gauge. The pointer will begin moving toward “0”. When the pointer reaches “0”, it is parallel with the outfeed table. Move the gauge to the front of the cutterhead and repeat the above procedure.

This adjusting process puts the knife into the knife slot with the tip parallel and flush with outfeed table. Once the correct knife height has been established, secure the gib locking screw beginning with the center screw to prevent bucking or uneven knife.
Repeat the procedure for the other two knives.

After the outfeed table has been set at the correct height, it should not be changed except for special operations or after replacing knives.

Example of incorrect setting:

If the outfeed table is too high, the finished surface of the work piece will be curved, Fig. 8.

If the outfeed table is too low, the work will be gouged at the end of the cut, Fig. 9.

As a final check of the outfeed table adjustment. Run a piece of wood slowly over the knives for 6 to 8 inches; it should rest firmly on both tables, as shown in Fig. 10, with no open space under the finished cut.

INFEED TABLE ADJUSTMENT

Loosen lock handle (A) and move table adjustment arm (B) to raise or lower infeed table. Gauge (C) shows the distance of travel, Fig. 11.

FENCE ADJUSTMENTS

To tilt the fence backward, loosen the lock screw (B) and tilt the fence (A), using the handle (C), Fig. 12. Use a machinist protractor or adjustable triangle to check the angle. A 45-degree tilt stop (D) is provided for quick placement of the fence at this angle.

To move the fence forward or backward across the table, loosen lock handle (E), then turn knob (F). When desire position is reached, retighten lock handle (E) securely.

OPERATING INSTRUCTION

NOTE: If you are inexperienced at jointing, use scrap pieces of lumber to check settings and get the feel of operations before attempting regular work.

CAUTION: ALWAYS USE GUARD AND KEEP HAND AWAY FROM CUTTHEAD.

HAND PLACEMENT

At the start of the cut, the left hand holds the work firmly against the front table and fence while the right hand pushes the work toward the knives. After the cut is under way, the new surface rests firmly on the outfeed table. The left hand should press down on this part, at same time maintaining flat contact with the fence. The right hand presses the work forward and before the right hand reaches the cutterhead it should be moved to the work on the outfeed table. FOLLOW THE 3 INCH RULE. NEVER PASS HANDS DIRECTLY OVER THE CUTTERHEAD.

EDGE JOINTING

This is the most common operation for the jointer. Set guide fence square with the table. Depth of cut should be the minimum required to obtain a straight edge. Hold the best face of piece firmly against the fence throughout the feed.

JOINTING WARPED PIECES

If the wood to be jointed is dished or warped, take light cuts until the surface is flat. Avoid forcing such material down against the table; excessive pressure will spring it while passing the knives, and it will spring back and remain curved after the cut is completed.

JOINTING SHORT OR THIN WORK

When jointing short or thin piece, use a push block to eliminate all danger to the hands. Two types are shown in Fig. 13.and are easily made from scrap material.

DIRECTION OF GRAIN

Avoid feeding work into the jointer against the grain. This will result in chipped and splintered edges, Fig. 14a. Feed with the grain to obtain a smooth surface, Fig. 14b.

BEVELING

To cut a bevel, lock the fence at the required angle and run the work across the knives while keeping it firmly against the fence and tables. Several passes may be necessary to arrive at the desired result.

TAPER CUTS

One of the most useful jointer operations is cutting an edge to a taper. The method can be used on a wide variety of work. Tapered legs of furniture are a common example.
Instead of laying the piece on the infeed table, lower the forward end of the work onto the outfeed table. Do this very carefully, as the piece will span the knives, and they will take a “bite” from the work with tendency to kick back unless the piece is firmly held. Now push the work forward as in ordinary jointing the effect is to plane off all the stock in front of knives to increase depth, leaving a tapered surface.

The ridge left by the knives when starting the taper may be removed by taking a very light cut according to the regular method for jointing, with the infeed table raised to its usual position. Practice is required in this operation, and the beginner is advised to make trail cuts on waste material. Taper cuts over part of the length and a number of other special operations can easily be done by the experienced craftsman.

MAINTENANCE

CAUTION: DISCONNECT MACHINE FROM POWER SOURCE BEFORE PERFROMING MAINTENANCE.

Check all screws and fasteners occasionally and keep them tighten securely.

In time, rust may appear on the table and fence and other parts of the jointer, resulting in less efficiency and accuracy of the machine, use paste wax which can be applied to prevent rust formation. If however, rust has already formed on those parts, use “Rust Remover” which will restore the machine to its original accuracy.

LUBRICATION

Use a good grade of light grease on the steel adjusting screws for the raising and lowering mechanisms of the infeed and outfeed work tables.
The cutterhead runs in two single-row sealed and shielded ball bearings, which are pre-lubricated for their entire life.

WHETTING KNIVES

1. Disconnect the machine from power source.

2. Use a fine carborundum stone. Cover it partly with paper as shown Fig. 15, to avoid marking the table.

3.  Lay the stone on the infeed table, lower the table and turn the cutterhead forward until the stone lies flat on the bevel of the knife.

4. Hold the cutterhead from turning, and whet the beveled edge
   of the knife, stroking lengthwise by sliding the stone back and forth across the table. Do the same amount of whetting on each of the three blades.

5. When finished, reset the knives parallel to the outfeed table (see “Setting Knives & Outfeed table”)

CUTTERHEAD REPAIRES

The entire cutterhead assembly may be removed for cleaning, bearing or blade replacement or any other cutterhead maintenance procedures. To remove it, lower both feed tables to clear the cutterhead. Remove the bearing, retaining stud and then the entire cutterhead assembly with bearings, studs and bearing housings (see exploded view pg. 16). Before reinstalling the assembly, be sure the machine’s curved seated of the base casting are free of dirt, dust grease, etc. to obtain a good tight fit.

BLADE CARE

When blade become dull enough so that it is noticeable when cutting, they should be resharpened a sharp blade works easier and dull blade is less blade life and greater wear and tear on all parts of the machine.
When the knife cannot be properly re-touched as described in “Whetting Knives” they must be ground and re-surfaced to a new bevel edge. Check in the “Yellow Pages” of your local phone  directory under “Sharpening Service” or “Tool Grinding or sharpening”. It may be less expensive to purchase a new set of blade.
Gum and Pitch which collects on the blades causes excessive  friction as the work continues, resulting in over heating the blade life. Use” Gum and Pitch Remover” to wipe off the blades.

TROUBLE SHOOTING

Raise outfeed table until it aligns with tip of knife.
Back end of stock is thicker than front end.| Knife is higher than outfeed table.| Raise outfeed table until it aligns with tip of knife.
Finished stock is concave in the middle.| Both tables have too much end fall.| Raise both table ends by adjusting four screws under the tables.
Ends of finished stock are cut more than the middle.| Table ends are raised higher than the middle.| Lower table ends by adjusting the four screws under the tables.
