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.
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.

Unpacking Open container and check for shipping damage. Report any damage immediately to your distributor and shipping agent. Do not discard any shipping material until the Planer is assembled and running properly. Compare the contents of your container with the following list to make sure all parts are intact. Report any missing parts to your distributor. Read this owner’s manual thoroughly for assembly, maintenance and safety instructions.
Installation and Assembly Tools required for assembly: Forklift or hoist with slings 10,12,13,16mm open-end wrenches 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.
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 13mm 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.
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. Recommended Gauges (AWG) of Extension Cords Extension Cord Length * Make sure the voltage of your power supply matches the specifications on the motor plate of the machine.
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.
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.
(You can also use any 3mm diameter tool, such as a hex wrench or drill bit for this purpose.) 9. Insert the screws for the first gib, turning them with the T-handle wrench. Do not fully tighten the screws; make them only snug enough to hold the knife in the groove. 10. Put the next gib in place, and repeat the process. See Figure 19. Use the adjustment pins and make sure the wings of the knife are completely in the cutterhead groove. Continue sequentially from one end of the cutterhead to the other end.
Work Table Parallel to Cutterhead The work table is set parallel to the cutterhead at the factory and no further adjustment should be necessary. If your machine is planing a taper, first check to see if the knives are set properly in the cutterhead. Then check to see if the work table is set parallel to the cutterhead. Proceed as follows: 1. Disconnect machine from power source. 2. Place the gauge block (Figure 21) on the work table directly under the edge of a knife as shown.
Anti-Kickback Fingers The anti-kickback fingers (A, Figure 23) are an important safety feature, as they help prevent kickback of stock. They operate by gravity and should be inspected frequently to make sure they are free of gum and pitch, so that they move independently and operate correctly. Infeed and Outfeed Roller Spring Tension The infeed roller (B, Figure 23) and outfeed roller (E, Figure 23) are those parts of your planer that feed the stock while it is being planed.
Outfeed Roller Height 1. Disconnect machine from power source. 2. Make sure the knives are set properly as explained under "Knife previously Adjustment." 3. Place the gauge block (F, Figure 26) on the table directly beneath the cutterhead (D, Figure 26). 4. Using a 0.032" (0.81mm) feeler gauge (G, Figure 26) placed on top of the gauge block, raise the work table until the knife just touches the feeler gauge when the knife is at its lowest point.
Chip Deflector The chip deflector (B, Fig. 28) keeps wood chips from falling into the outfeed roller. The deflector should be set approximately 1/16" to 1/8” from the tip of the knives. Make sure the deflector is oriented so the bevel on its front edge matches the shape of the cutterhead. Feed Speed Control Your machine is equipped with a spiral, serrated infeed roller and a solid steel outfeed roller. When the feed rollers are engaged, they turn to feed the stock.
Depth of Cut Periodically check all the chains for proper tension and adjust accordingly if required. The cutting depth scale is a combination inch/metric scale (Figure 33), with a cutting range from 0 to 6" (152.4mm). A manual scale is mounted directly to the front column. The model 15S planer also features a digital scale for easier, more precise depth readings. The table should be kept clean and free of rust. Some users prefer a paste wax on exposed steel and cast iron surfaces.
The item numbers on this chart are referenced to the surrounding illustrations. No.
IMPORTANT: Always place the digital display in relative (“INC”) mode before turning it off. If you turn it off while in absolute (“ABS”) mode, your absolute setting will default to zero. Functions of the Digital Scale (Model 15S only) Figure 40 identifies the parts of the digital scale. The button functions are discussed below, followed by a section giving practical examples of how to calibrate your settings, and how these functions can be used for daily planer operations.
From this point on, any table movement will be based off this setting. The setting will be kept in the device’s memory even when the digital display is turned off, and only needs re-setting after a battery has lost charge and needs replacing. TOL – tolerance setting This function is not generally used in planer operations, but is here explained for reference. Press TOL, and an up-arrow indicator will appear, as well as a flashing “SET” indicator. You can now change the upper tolerance limit.
Method 2 uses a scrap board and calipers. 1. You have planed a board at a setting of one inch at absolute measurement. Do not move the table from this position. You wish to increase the depth of cut on the next run by .063 inches. 1. Turn on the digital display. It turns on in absolute mode. 2. Plane one side of a scrap board at an appropriate and safe cutting depth (1/16” for example). 2. Press ABS button to start relative measurement mode (“INC” will appear on the display). 3.
Troubleshooting: Performance Problems Trouble Probable Cause Remedy 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. 15S: Sharpen or replace knives. 15HH: Rotate or replace inserts. Lumber not butted properly. Butt end to end each piece of stock as they pass through.
Troubleshooting: Mechanical and Electrical Problems Trouble Uneven depth of cut side to side. Board thickness does not match depth of cut scale. Chain is jumping. Machine will not start/restart or repeatedly trips circuit breaker or blows fuses. Probable Cause Remedy Knife projection from cutterhead is incorrect (15S only). Adjust knife projection. Table not parallel to cutterhead. Adjust table/cutterhead parallelism. Depth of cut scale is incorrect. Adjust depth of cut scale. Inadequate tension.
Trouble Probable Cause Remedy Motor starter failure. Examine motor starter for burned or failed components. If damage is found, replace motor starter. If motor starter looks okay but is still suspect, you have two options: have a qualified electrician test the motor starter for function, or purchase a new starter and establish if that was the problem on changeout.
Troubleshooting: Digital Scale – Model 15S only Trouble Probable Cause Remedy Flashing digits. Low voltage. Replace battery. Locked digits. Haphazard memory. Take battery out, wait thirty seconds, then re-insert it. Poor contact of battery. Improve battery contact. Low voltage. Replace battery. Displays only ‘0000’. Short-circuit of zero setting spring and slider signal source. Remove frame and adjust spring. Function buttons won’t work. Distortion of springs from overpressing.
