PROCEDURE

   Max depth of cut is 1/8 inch
   Max width of stock is 13 inches
   Lower the carriage to the desired height for your first pass.
   Turn the unit on and feed the material into the feed rollers.
   Examine the finished cut and adjust the carriage to the appropriate height for your next pass.
   Flip the board back and forth between each pass.
   For best results, plane both sides of the workpiece to reach a desired thickness. For example, if you need to remove 1/8" (3 mm) from your workpiece, remove 1/16" (1.6 mm) from each side. This not only allows the workpiece to dry with an even moisture content, it also produces finer cuts.
   Always plane in the direction of the grain.
   Support the workpiece adequately at all times.
   Planing material less than 3/4" (19 mm) wide is not recommended.
   If you must plane narrow material, group several pieces together and plane them as one wide workpiece whenever possible.
   The maximum depth of cut your planer can take in one pass is 1/8" (3 mm) [on material less than 6" (152 mm) wide].
   Never attempt to modify your planer to take a deeper cut.
   Snipe is a depression made when an unsupported end of your material drops toward the floor, causing the opposite end to lift up into the cutterhead.
       To Avoid Snipe Feed the workpiece into the planer so it is level and remains flat against the base at all times.
       Keep the workpiece level throughout planing operation by receiving or “catching” it from the rear of the planer.
       If you are planing material that is especially long, the use of additional material support.
   Twisted, Cupped and Bowed Wood
       If both sides of your material are very rough or if the material is cupped, bowed or twisted, your planer may not produce the desired result.
       Ideally, you should have at least one level face/surface on your material before you plane.
       Your thickness planer will work best with material that has been run through a jointer to produce one flat surface.
       Twisted wood may jam your thickness planer. If a jam occurs, turn the power off, disconnect the power supply and raise the carriage to release the material from the cutterhead.
       If your material is only slightly twisted: Plane both sides alternating from one to the other until the desired thickness is reached.
       To obtain the best possible results with cupped wood: Rip the material down the middle and plane it as two separate pieces. Ripping the material reduces the severity of the cup and allows the machine to deliver better results.
       You will have to remove more material on cupped wood to achieve the desired thickness than you would on a normal board.
       If Ripping the Material is Not an Option Plane one side of the material until flat, then plane the opposite side until it is also flat. NOTE: Do not flip the board back and forth between each pass if wood is cupped.
       To Plane Bowed Wood - The feed rollers and cutterhead in your planer will push the bow out of the material as it feeds. However, when the material exits the planer, the pressure of the rollers and cutterhead will release allowing the wood to spring back into a bowed formation. To properly remove the bow, use a jointer.

TROUBLESHOOTING

Problem


Possible Cause


Possible Solution

If the material does not feed properly


Check for dull knives


Rotate or replace as necessary



Check for excess clogging in the dust shroud




Check for excess oil/debris/pitch on feedrollers




Check for excessively twisted, cupped or bowed material




Check for a broken drivebelt


If the circuit breaker trips repeatedly


Dull knives


Dull knives can cause motor overloading, rotate or replace as necessary. NOTE: Circuit breaker overload is often the result of dull knives. If the circuit breaker on your planer trips, check the sharpness of your knives before attempting to reset the breaker in order to continue planing



The depth of cut is higher


An overly aggressive cut could cause motor overloading



The feed rate is higher


Drop feed rate to 14 ft/min. A reduction in feed rate will reduce the

load on the motor and prevent breaker trips.

If the unit does not run


Check to see if the unit is plugged in


Ensure unit is plugged into the appropriate outlet



Check to see if the top cover is

properly in place




Check to see if the dust shroud is

properly in place




Check to see if the circuit breaker

needs to be reset


If chips do not eject from the rear of

the unit


Check for excess clogging in the

dust shroud and fan




Check to see if the dust shroud is

properly in place


If the branch (house/shop) circuit

breaker trips repeatedly


Even under normal loading conditions,

other electrical loads on the same

branch circuit may cause the circuit

breaker to trip


Unplug or turn off other devices sharing the circuit with the planer

OR use the planer on another branch circuit by itself



Dull knives


Dull knives can cause motor overloading, rotate or replace as

necessary



The depth of cut is higher


An overly aggressive cut could cause motor overloading



The feed rate is higher


Drop feed rate to 14 ft/min. A reduction in feed rate will reduce the

load on the motor and prevent breaker trips
