Warning

As with all machines, there is a certain amount of hazard involved with the use of this planer. Use the machine with the respect and caution demanded where safety precautions are concerned. When normal safety precautions are overlooked or ignored, personal injury to the operator can result.

Read, understand and follow the safety and operating instructions found in this manual. Know the limitations and hazards associated with this machine.

Electrical grounding. Make certain that the machine frame is electrically grounded and that a ground lead is included in the incoming electrical service. In cases where a cord and plug are used, make certain that the grounding plug connects to a suitable ground. Follow the grounding procedure indicated in the National Electrical Code.

Eye safety. Wear an approved safety shield, goggles, or glasses to protect eyes. (NOTE: Common eyeglasses are only impact-resistant, they are not safety glasses.)

Personal protection. Before operating the machine, remove tie, rings, watch and other jewelry and roll up sleeves above the elbows. Remove all loose outer clothing and confine long hair. Protective type footwear should be used. Where the noise exceeds the level of exposure allowed in Section 1910.95 of the OSHA Regulations, use hearing protective devices. Do not wear gloves.

Guards. Keep the machine guards in place for every operation for which they can be used. If any guards are removed for maintenance, DO NOT OPERATE the machine until the guards are reinstalled.

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

Work area. Keep the floor around the machine clean and free of scrap material, saw dust, oil and other liquids to minimize the danger of tripping or slipping. Be sure the table is free of all scrap, foreign material and tools before starting to cut. Make certain the work area is well lighted and that a proper exhaust system is used to minimize dust. It is recommended that anti-skid floor strips are used on the floor area where the operator normally stands and that each machine’s work area be marked off. Provide adequate work space around the machine.

Avoid accidental starting: Make certain motor switch is in off position before connecting power to the machine.

Operator position. Maintain a balanced stance and keep your body under control at all times. Stand to one side out of line with the table and make sure no one else is standing in line with the table.

Housekeeping. Before turning on machine, remove all extra equipment such as keys, wrenches, scrap, and cleaning rags away from the machine

Careless acts. Give the work you are doing your undivided attention. Looking around, carrying on a conversation, and “horseplay” are careless acts that can result in serious injury.

Disconnect machine before performing any service or maintenance or when changing blades. A machine under repair should be RED TAGGED to show it should not be used until the maintenance is complete.

Maintain tools in top condition. Keep tools sharp and clean for safe and best performance. Dull tools increase noise levels and can cause kickbacks and glazed surfaces. Check the condition and adjustment of the tools before making any cuts. Follow the sharpening instructions on knife grinding and jointing, installing and adjustments.

Hand safety. Keep hands outside the machine. NEVER reach under the guards to try to clear stock that stops feeding. Do not clear chips and sawdust with hands; use a brush. Do not have any part of the hands under that part of the board that is over the table when starting a cut; the infeed roll will engage the board and force it down against the table causing a pinching action. Do not operate machine while the gear cover is open.

Cutterhead rotation: Be sure cutterhead rotates under power in a counterclockwise direction when viewed from the main drive motor side.

Material condition: Do not plane boards with loose knots or with nails or any foreign material on its surface. Knife impact on these objects can cause the knives to be pulled out and cause them to shatter against the chipbreaker or pressure bar. Twisted, warped, or in wind stock should first be jointed on one surface before attempting to plane a parallel surface on the planer. Serious stock flaws cannot be removed by use of a planer alone.

Machine adjustments: Make all machine adjustments with power off except feed rate.

Job completion. If the operator leaves the machine area for any reason, the planer should be turned

"off" and the cutterhead should come to a complete stop before his departure. In addition, if the operation is complete, he should clean the planer and the work area. Never clean the planer with power "on" and never use the hands to clear sawdust and debris; use a brush.

Replacement parts. Use only Powermatic or factory authorized replacement parts and accessories; otherwise the warranty and guarantee is null and void.

Misuse. Do not use this Powermatic planer for other than its intended use. If used for other purposes, Powermatic disclaims any real or implied warranty and holds itself harmless for any injury or damage which may result from that use.

If you are not thoroughly familiar with the operation of planers, obtain advice from your supervisor, instructor or other qualified person.

Drugs, alcohol, medication. Do not operate this machine while under the influence of drugs, alcohol, or any medication.

Health hazards. Some dust created by power sanding, sawing, grinding, drilling and other construction activities 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 and chromium from chemically-treated lumber. Your risk from these exposures varies, depending on how often you do this type of work. To 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.

Familiarize yourself with the following safety notices used in this manual:

This means that if precautions are not heeded, it may result in minor injury and/or

possible machine damage.

This means that if precautions are not heeded, it may result in serious injury or possibly

even death.

Installation and Assembly

Tools required for assembly:

Forklift or hoist with slings 10-12,12-14mm open-end wrenches (provided) 4 and 5mm hex wrenches (provided) 16mm open-end wrench

Remove the screws holding the planer to the pallet and use a forklift or hoist to lift the planer off the pallet. Forks and straps should always be placed under the four lifting handles when lifting this machine (Figure 5). The lifting handles can be pushed back in when not in use.

The planer should be operated in a well-lit area with good ventilation. It can be rolled on its casters to the desired location. Press the foot pedal (Figure 6) to prevent movement during operation or adjustments.

Exposed surfaces, such as tables, rollers, cutterhead, etc., have been given a protective coating at the factory. This should be removed with a soft cloth moistened with a good commercial solvent. Do not use acetone, gasoline, lacquer thinner, or other solvents with a low flash point. Do not use an abrasive pad because it may scratch the polished cast iron surfaces.

Figure 5

Figure 6

Use care when cleaning

around the cutterhead area – knives are extremely sharp!

Handwheel

1. Place the key into the slot on the shaft

(Figure 7), and mount the handwheel to the shaft, making sure it is oriented so it slips over the key.

2. Peel off the backing of the directional label,

and attach it to the center of the handwheel. Place flat washer and hex nut on shaft and tighten with 16mm wrench.

3. Mount the handle in the threaded hole in the

handwheel, and tighten with a 12mm wrench placed over the flat on the handle.

Starter Box

Mount the controls as shown in Figure 8, with the two socket head cap screws which you’ll find mounted to the head casting. Use a 5mm hex wrench.

Figure 7

Figure 8

Extension Tables

1. Mount a cast iron table to the edge of the

main table with three M8 x 25 hex cap screws (Figure 9) using a 12mm wrench. Do not fully tighten yet.

2. The extension table must be leveled with the

main table. Place a straight edge (such as a jointed board) across the extension table and the main table.

NOTE: The straight edge should not lie over the raised table rollers, as this would distort the leveling process. Either place the straight edge just short of the table rollers, or lower the table rollers completely into the table (see page 11) while mounting the extension tables.

3. Insert three socket set screws with a 4mm

hex wrench, and screw them in or out as needed until tables are level.

4. Securely tighten the hex cap screws.

5. Mount the second extension table to the

opposite side of the planer table, using the same procedure.

Figure 9

Dust Hood

Mount the dust hood to the rear of the head casting with three M6 x 12 socket head cap screws with lock washers, and three M5 x 10 hex cap screws with flat washers. See Figure

10.

It is recommended that you use a dust collection system with this planer. If you are not using a dust collection system, do not attach the dust hood to the planer, as the accumulation of dust inside the hood may create a safety hazard, or eventually cause jamming of the rollers.

Electrical Connections

Electrical connections must

be made by a qualified electrician in compliance with all relevant codes. The machine must be properly grounded to help prevent electrical shock and possible fatal injury.

A power plug is not provided with the 15S or 15HH planers. You may either connect a 230 volt plug or "hard-wire" the machine directly to your electrical panel provided there is a disconnect near the machine. Consult electrical schematic on page 38 for further clarification of wiring setup.

Figure 10

This machine must be grounded. Grounding provides a path of least resistance to help divert current away from the operator in case of electrical malfunction.

Make sure the voltage of your power supply matches the specifications on the motor plate of the machine.

Extension Cords

The use of an extension cord is not recommended for this machine, but if one is necessary make sure the cord rating is suitable for the amperage listed on the machine's motor plate. An undersize cord will cause a drop in line voltage resulting in loss of power and overheating.

The chart in Figure 11 shows the correct size cord to use based on cord length and motor plate amp rating. If in doubt, use the next heavier gauge. The smaller the gauge number the heavier the cord.

Adjustments

Tools required for assembly:

10, 12 and 17mm open-end wrenches 3, 5 and 6mm hex wrenches

0.2” (0.5mm) feeler gauge straight edge gauge block cross-point screwdriver

Disconnect machine from

power source before making any adjustments (except feed rate).

Belt Tension

Inspect the tension of the belts frequently during the first few times you use the planer. Belts often stretch during this trial period. If they require tightening, proceed as follows:

1. Remove the belt guard and the rear panel.

2. Loosen the bottom nut on the motor

adjustment screw (Figure 12) with a 17mm wrench.

3. Turn the top nut on the adjustment screw to

lower the motor plate, which will increase the belt tension.

4. Proper tension is achieved when there is

slight deflection in the belt midway between the pulleys, using moderate finger pressure.

5. Tighten the bottom nut on the adjustment

screw (Figure 12).

Figure 12

Pulley Alignment

The pulleys should be in line for proper belt operation.

1. Remove the belt guard and place a straight

edge against the faces of both pulleys (Figure 13).

2. If the straight edge does not lie flat on both

pulley faces, open the rear panel and loosen the four hex nuts on the motor plate (see Figure 12) with a 12mm wrench.

3. Nudge the motor left or right until the pulleys

are in alignment.

4. Tighten hex nuts and replace covers.

Table Rollers

Your planer is supplied with two table rollers (Figure 14) which turn as the stock is fed into the machine, thus reducing friction. It is not possible to give exact dimensions on the proper height setting of the table rollers because each type of wood behaves differently. As a general rule, however, when planing rough stock the table rollers should be set at high position. When planing smooth stock the rollers should be set at low position.

Figure 13

NOTE: When raising the roller higher above the table, the range is from zero to 0.06" (Figure 15).

Figure 15

The table rollers are factory set for average planing and are parallel to the table surface. If you desire to adjust the table rollers higher or lower, proceed as follows:

1. Disconnect machine from power source.

2. Lay a straight edge across both rollers.

3. On one side of the table, loosen the set

screws (Figure 16) with a 3mm hex wrench, and turn the eccentric shafts to raise or lower the rollers.

4. When proper height is achieved, tighten set

screws.

Figure 14

Figure 16

5. Adjust the rollers from the opposite side of

the table in the same manner.

IMPORTANT: Be sure that the height of front and rear rollers are the same. And the table rollers must always be set parallel to the table.

Cutterhead

Although your planer was carefully adjusted at the factory, it should be checked before being put into operation. Any inaccuracies due to rough handling in transit can be corrected by following the directions in this manual.

To check the adjustments you will need feeler gauges, and a dial gauge or home-made gauge block made of hardwood. This gauge block can be made by following the dimensions shown in Figure 17.

Replacing Knives (Model 15S only)

Figure 17

Use caution and proceed

slowly when working with and around the knives – they are extremely sharp!

When dull knives are replaced, care must be exercised in setting the new knives into the cutterhead. There is a certain procedure to follow which will ensure a proper setting of knives on the 15S Planer. Proceed as follows:

1. Disconnect machine from power source.

2. Remove the dust hood and the top cover.

Remove the chip deflector (Figure 28 shows the chip deflector). Remove the belt guard so you can rotate the cutterhead using the pulley.

3. Remove the gib screws with the T-handle

hex wrench, as shown in Figure 18, and remove each gib one at a time.

4. Carefully remove the knife, and clean the

cutterhead slot of any dust or debris.

5. Place the new knife into the cutterhead slot.

6. IMPORTANT: As you proceed with knife

installation, make sure the wings on both ends of each hole (see Figure 18) are completely inserted into the groove in the cutterhead. Failure to do this may result in knife breakage during operation.

Figure 18 – Model 15S only

7. There are a total of three short gibs and

twelve long gibs on the cutterhead. It is not important whether long or short gib is used in any particular location along the knife. Of course, each knife must use one short gib.

8. Put the first gib in place at the end of the

cutterhead. Use the knife adjustment pins shown in Figure 19. The adjustment pins fit down through the smaller holes in the gib, knife, and cutterhead, helping to align them.
