L16-20

In the event of an electrical short, grounding reduces the risk of electric shock by providing a path of least resistance to disperse electric current. This tool is equipped with an electric cord that has an equipment-grounding conductor which must be properly connected to a grounding plug. The plug must be plugged into a matching outlet that is properly installed and grounded in accordance with all local codes and ordinances. Improper connections of the electrical-grounding conductor can result in the risk of electric shock.

This equipment must be grounded. Verify that any existing electrical out let and circuit you intend

to plug into is actually grounded. Under no cir cumstances should the grounding pin from any three-pronged plug be removed. Serious injury may occur.

Extension Cords

We do not recommend the use of extension cords on 220V equipment. It is much better to arrange the placement of your equipment and the installed wiring to eliminate the need for exten sion cords.

Clean Up

Site Considerations

The unpainted surfaces are coated with a waxy oil to protect them from corrosion during ship ment. Remove this protective coating with a sol vent cleaner or citrus-based degreaser such as Grizzly’s G7895 Degreaser. To clean thoroughly, some parts may need to be removed. For opti

mum performance from your machine, make sure you clean all moving parts or sliding contact surfaces that are coated. Avoid chlo

rine-based solvents as they may damage painted surfaces should they come in contact. Always follow the manufacturer’s instructions when using any type of cleaning product.

Do not use gasoline or other petroleum-based solvents to clean with. They have low flash points which make them extremely flammable. A risk of explosion and burning exists if these pr od uc ts a re u se d.

Many of the solvents commonly used to clean machinery can be toxic when inhaled or ingest ed. Always work in wellventilated areas far from potential ignition sources when dealing with sol vents. Use care when dis posing of waste rags and towels to be sure they do not create fire or environ mental hazards.

FLOOR LOAD

Your Extreme Duty Planer represents a very large weight load in a moderate sized footprint. Most commercial shop floors will be adequate for the weight of the planer. Some floors may require additional support. Contact an architect or struc tural engineer if you have any question about the ability of your floor to handle the weight.

WORKING CLEARANCES

Working clearances can be thought of as the distances between machines and obstacles that allow safe operation of every machine with out limitation. Consider existing and anticipated machine needs, size of material to be processed through each machine, and space for auxiliary stands and/or work tables. Also consider the rela tive position of each machine to one another for efficient material handling. Be sure to allow your self sufficient room to safely run your machines in any foreseeable operation.

LIGHTING AND OUTLETS

Lighting should be bright enough to eliminate shadow and prevent eye strain. Electrical circuits should be dedicated or large enough to handle combined motor amp loads. Outlets should be located near each machine so power or exten sion cords are not obstructing high-traffic areas. Be sure to observe local electrical codes for prop er installation of new lighting, outlets or circuits.

Make your shop “child safe.” Ensure that your workplace is inaccessible to children by closing and locking all entrances when you are away. Never allow visitors in your shop when assembling, adjusting or operating equip ment.

Extreme Duty Planers -13-

SECTION 6: ASSEMBLY

Beginning Assembly

Most of your Extreme Duty Planer has been assembled at the factory, but some parts must be assembled or installed after delivery. We have organized the assembly process into steps. Please follow along in the order presented in this section.

Keep loose clothing out of the way of machin ery and keep hair pulled back.

Disconnect power to the machine when perform ing any maintenance or assembly. Failure to do this may result in serious personal injury.

Dust Hood

A dust hood with a 5" dust port comes with the planer for dust collection purposes. Install the dust hood with M6-1.0 x 10 screws. The dust hood should look like Figure 4 when installed.

Figure 4. Dust hood installed.

Wear safety glasses during the entire assembly process. Failure to com ply may result in serious personal injury.

Planer knives are dangerously sharp! Use extreme caution when working near cutting surfaces. Failure to exercise care while working near knives could result in severe injury.

-14- Extreme Duty Planers

Table Rollers

2. Determine the appropriate height for the type

of stock you are using.

The height of the table rollers will vary, depending on the type of material you intend to plane. When planing rough stock, you will need to set the roll ers high to keep the lumber from dragging along the table. Milled lumber should be planed with the rollers set lower.

To adjust the table rollers correctly:

1. Loosen the lock on the adjustment lever

shown in Figure 17. Pull the lever up to raise the table rollers.

Height

Scale

Lock

The scale at the base of the adjustment lever

is numbered “0”, “1” and “2”. These numbers

represent how many millimeters the top of the rollers are above the surface of the table.

Since 1mm = .03937", figure that each notch

on the scale is approximately .004". The ideal tolerance for the height of the table roll ers is between .002"-.016".

Note—If the table rollers are too high, snipe

or chipping may occur at the ends of the workpiece. Only use the higher settings for rough cut lumber. If you are unsure about which height to use, experiment on scrap lumber by using the trial and error method. Always start at the smaller tolerances and work up.

3. Pull the adjustment lever up to the appropriate scale marks. Secure the adjustment lever by tightening the lock.

Read the entire manual before making any cuts with your planer. Serious personal injury may result if safety or operational information is not understood or followed.

Test Run

Once assembly is complete and adjustments are done to your satisfaction, you are ready to start the machine.

Turn on the power supply at the main panel. Press the START button. Make sure your finger is poised on the is a problem. The planer should run smoothly with little or no vibration or rubbing noises. Strange or unnatural noises should be investigated and cor rected before operating the machine further.

Run the planer for a short time to ensure that the moving parts are working properly with no exces sive vibration. If any problem develops, correct it before attempting to use the machine.

If you cannot locate the source of unusual noises or cannot fix any problems that arise, immediately contact our Service Department at (570) 5469663 for help.

SECTION 7: OPERATIONS

Operational Tips

Keep loose clothing out of the way of machin ery and keep hair pulled back.

Disconnect power to the machine when perform ing any adjustments or maintenance. Failure to do this may result in seri ous personal injury.

• Inspect lumber for defects, warping, cupping, twisting, and foreign objects (nails, staples, imbedded gravel, etc.). If you have any question about the quality of your lumber, do not use it. Remember, wood stacked on a concrete floor can have small pieces of stone or concrete pressed into its surface.

• Use the full width of the planer, Alternate between the left, the right and the middle when feeding lumber into the planer. Your knives will remain sharp much longer.

• Scrape all glue off of joined boards before planing.

Wear safety glasses during all operations on the planer. Failure to com ply may result in serious personal injury.

Always wear a dust mask when operating the plan er. Using this machine produces sawdust which may cause allergic reac tions or respiratory prob lems.

NOTICE

If you are not familiar with how to properly use a planer. WE STRONGLY RECOMMEND that you read books, trade magazines, or get formal training.

• Plane ONLY natural wood fiber (i.e. DO NOT plane wood composites).

• Surface wood with the grain. NEVER feed end-cut or end-grained lumber into your planer.

• DO NOT use boards with knots, splits, cross grain or other obvious blemishes or defects.

They can damage the machine and pose the possibility of operator injury.

• Keep your work area clear.

• Avoid planing wood with a high water con tent. Wood with more than 20% moisture content or wood exposed to rain or snow will plane poorly and cause excessive wear to the knives and the motor. Excess moisture can also hasten rust and corrosion.

• During operation, always use the table height lock knob for consistent and accurate results.

• Always true any cupped or warped stock on a jointer before planing.

Extreme Duty Planers -17-

Wood Characteristics

The species of wood, as well as condition, will affect planing ability—the harder the wood, the more difficult it will be to plane. We have included a list of wood characteristics you may encoun ter when planing, The following descriptions of defects will give you some possible answers to problems that may arise.

snipe is unlikely. More likely, you will be able to reduce it to a tolerance of .002". If snipe under that level is a problem, consider cutting lumber longer that your intended work length and cut off the excess after planing is completed.

Uneven Knife Marks — Uneven knife marks can occur when the chip breaker is set too high. Inspect cutterhead bearings if re-adjustment of the chip breaker fails to remedy the situation.

Chipped Grain (Tear Out) — Usually a result of cutting against the grain, or planing wood with knots or excessive amount of cross grain. Chipped grain can also be caused by dull knives or misaligned chip breaker. Often, chipped grain can be avoided by slowing down the feed rate and by taking shallow cuts, If those options do not work, inspect your lumber and determine if its grain pattern is causing the problem. If the wood does not show substantial crossgrain, inspect your knives for sharpness and inspect the chip breaker for proper alignment.

Fuzzy Grain (Raised Grain) — Usually caused by surfacing lumber with too high of a moisture content. Sometimes fuzzy grain is a characteristic of wood such as basswood. Fuzzy grain can also be caused by dull knives or an incorrect grinding bevel. Check with a moisture meter. If moisture is greater than 20%, sticker the wood and allow it to dry. Otherwise, inspect the knife condition.

Glossy Surface — Usually caused by dull knives taking shallow cuts at a slow feed speed. Surface gloss will usually be accompanied by overheat ing. Lumber will often be scorched and eventually damage to the knives will occur. If the knives are sharp on inspection, increase feed speed or cut ting depth.

Snipe — Occurs when board ends have more material removed them the rest of the board. Usually caused when one or both of the table roll ers are set too high. Can also be caused by the chip breaker or pressure bar being set too high. However, a small amount of snipe is inevitable. Snipe can be minimized by proper adjustment of the planer components, but complete removal of

Chatter Marks — Usually caused by incorrect chip breaker and pressure bar setting heights. Chatter marks can also be caused by running a narrow wood piece through the planer at either the right or left end of the cutterhead. Chatter, like uneven knife marks, will show in the form of a “washboard” look. Chatter marks are more likely to be inconsistent in appearance than uneven knife marks.

Wavy Surface — Caused by poor knife height adjustment, wavy surface appears when one knife is taking deeper cuts than the rest of the knives. Remedy by resetting the knives to a toler ance of approximately .001" from one end to the other.

Pitch & Glue Build-Up — Glue and resin buildup on the rollers and the cutterhead will cause overheating by decreasing cutting sharpness while increasing drag in the feed mechanism. The result can include scorched lumber as well as uneven knife marks and chatter.

Chip Marks — Occur when chips are not prop erly expelled from the cutterhead. The knives catch the chips and drag them across the lum ber being planed. Chips tend to be random and non-uniform (compared to chipped grain). This problem can be caused by exhaust blockage or too much room between the cutterhead and the chip deflector. Using a dust collection system in combination with the planer can help reduce chip marks. Inspect the chip deflector and re-adjust spring tension.

SECTION 8: MAINTENANCE

Table

Disconnect power to the machine when perform ing any adjustments or maintenance. Failure to do this may result in seri ous personal injury.

The table and other non-painted surfaces on the Extreme Duty Planer should be protected against rust and pitting. Wiping the table clean after every use ensures that wood dust isn’t allowed to trap moisture against bare metal surfaces.

General

Periodic maintenance on your 20" Extreme Duty Planer Planer ensures its optimum performance. Make a habit of inspecting your planer each time you use it.

Check for the following conditions and repair or replace when necessary.

• Loose mounting bolts.

• Worn switch.

• Worn or damaged cords and plugs.

• Damaged V-belt.

• Any other condition that could hamper the

safe operation of this machine.

Tables can be kept rust-free with regular applica tions of products like Boeshield term storage you may want to consider products like Kleen Bore's Rust Guardit™.

Lubrication

The Extreme Duty Planers have four lubrication points that need to be lubricated according to planer usage. Always lubricate more often under dusty/dirty conditions. As a general rule, lubricate as follows:

1. Micro-Adjustment Knob — Once a week for heavy use; once a month for moderate use. See Figure 20 for grease fitting loca tion.

Cleaning

Regularly blow out cabinet, feed rollers, chip

breakers and cutterhead with compressed air (always wear safety glasses and a dust mask when doing this) and keep the dust port clear.

Figure 20. Micro-adjust grease fitting.

2. Transmission Box — Lubricate after every 12 hours of continuous use. See Figure 21 for location.

Figure 21. Transmission box grease fitting.

3. Table Lifting Gears — Once a week for

heavy use; once a month for moderate use. See Figure 22 for locations.

Avoid getting grease or oil on the V-belts or pulleys. Check the V-belts, as part of a monthly inspection for proper tension and belt condition. Cracking and glazing could result in belt failure. Replace the belt if such conditions appear.

To loosen/tighten belt tension:

1. Thread in the motor mount adjustment bolts

(Figure 23) to loosen the V-belt. Unthread the adjustment bolts to tighten the V-belt.

4. Chain — Clean and regrease as determined

by visible inspection for dust or grime in the chain grease.

Always wipe off excess grease from all loca tions after lubricating!
