Proceed as follows: 1. Connect power, and turn on the planer. 2. Take a scrap board and measure its exact thickness with calipers. 3. Raise or lower the table so the scale reads the thickness of the board minus 1/16". Feed the board through the planer. 4. Move the table up another 1/16". Flip the board over and plane the other side. 5. Measure the board with calipers and compare with the depth scale on the planer. If the scale needs adjustment, loosen the screws and shift the scale up or down as needed. Tighten screws when finished. Figure 32 19 Maintenance Disconnect machine from power source before performing any maintenance. Periodic or regular inspections are required to ensure that the machine is in proper adjustment, that all screws are tight, that belts are in good condition, that dust has not accumulated in the electrical enclosures, and that there are no worn or loose electrical connections. Buildup of sawdust and other debris can cause your machine to plane inaccurately. Periodic cleaning is not only recommended but mandatory for accurate planing. Close-fitting parts, such as the cutterhead slot and gibs, should be cleaned with a cloth or brush and non-flammable solvent, and freed from clinging foreign matter. Remove resin and other accumulations from feed rollers and table with a soft rag and nonflammable solvent. Periodically check all the chains for proper tension and adjust accordingly if required. TIP: If a foreign object nicks the knives, instead of throwing them away or trying to grind out the deep nick, simply stagger the knives in the head, moving one knife no more than 1/4" to the right and another knife no more than 1/4" to the left. The nick should no longer be noticeable. The table should be kept clean and free of rust. Some users prefer a paste wax coating. Another option is talcum powder applied with a blackboard eraser rubbed in vigorously once a week; this will fill casting pores and form a moisture barrier. This method provides a table top that is slick and allows rust rings to be easily wiped from the surface. Important also is the fact that talcum powder will not stain wood or mar finishes as wax pickup does. Lubrication The bearings on the cutterhead are factory lubricated and sealed for life – no lubrication is required. GEARBOX LUBRICANT The lubricant in the gear box must be replaced every 2,500 hours. Multi-purpose gear box lubricant will be suitable. To replace the lubricant: 1. Remove the drain plug (A, Figure 33) with a 14mm wrench, and remove filler cap (B- Figure 33). Drain dirty oil thoroughly. 2. Tighten the drain plug (A, Figure 33). 3. Fill with clean lubricant through hole (B, Figure 33). 4. Tighten filler cap (B, Figure 33).

(NOTE: Snipe cannot be eliminated, but can be so minimized as to be negligible.) Table rollers not set properly. Adjust rollers to proper height. Inadequate support of long boards. Support long boards with extension rollers. Uneven feed roller pressure front to back. Adjust feed roller pressure. Dull knives or knife inserts. 209: Sharpen or replace knives. 209HH: Rotate or replace inserts. Lumber not butted properly. Butt end to end each piece of stock as they pass through. Fuzzy grain. Planing wood with high moisture content. Remove moisture by drying, or use different stock. Dull knives or knife inserts. 209: Sharpen or replace knives. 209HH: Rotate or replace inserts. Torn grain. Too heavy a cut. Adjust proper depth of cut. Knives (or inserts) cutting against the grain. Cut along the grain where possible. Dull knives or knife inserts. 209: Sharpen or replace knives. 209HH: Rotate or replace inserts. Rough/raised grain. Dull knives or knife inserts. 209: Sharpen or replace knives. 209HH: Rotate or replace inserts. Too heavy a cut. Adjust proper depth of cut. Planing wood with high moisture content. Remove moisture by drying, or use different stock. Rounded, glossy surface. Dull knives or knife inserts. 209: Sharpen or replace knives. 209HH: Rotate or replace inserts. Feed rate too slow. Increase feed rate. Cutting depth too shallow. Increase cutting depth. Poor feeding of lumber. Inadquate feed roller pressure. Adjust feed roller tension. If proper tension cannot be achieved, replace feed rollers. Planer table rough or dirty. Clean pitch and residue from table, and apply paste wax. Belt slipping on pulleys. Tighten belt.
