Planing refers to the sizing of lumber to a desired thick-

ness while creating a level surface parallel to the oppo-

site size of the board. Depth of cut is the term used to

indicate how deep the blades will cut into the workpiece.

OPERATION SAFETY RULES

WARNING: Operation of any power tool can result in

foreign objects being thrown into eyes which can result

in severe eye damage. Always wear safety goggles

complying with United States ANSI Z87.1 (shown on

package) before commencing power tool operation.

CAUTION: Always observe the following safety

precautions:

• Know general power tool safety. Make sure all

precautions are understood (See pages 2, 3 and 7).

• Whenever adjusting or replacing any parts on planer,

turn switch off and remove plug from power source.

• Make sure the cutterhead and chipbreaker covers

are properly attached and securely fastened.

• Make sure all moving parts are free from interference.

• Always wear eye protection or face shield.

• Make sure blades are aligned and properly attached

to cutterhead.

• Do not plug in planer unless switch is in OFF posi-

tion. After turning switch on, allow planer to come to

full speed before operating.

• Keep hands clear of all moving parts.

• Do not force cut. Slowing or stalling will overheat

motor. Allow automatic feed to function properly.

• Use quality lumber. Blades last longer and cuts are

smoother with good quality wood.

• Do not perform planing operations on material short-

er than 23", narrower than 3/4",or less than 1/2"thick.

• Never make planing operation on material wider than

20" or cut deeper than 1/8"

• Always keep cutterhead and blade guards in proper

working condition.

• Maintain the proper relationships of infeed and out-

feed table surfaces and cutterhead blade path.

• Do not back the work toward the infeed table.

• Support the workpiece adequately at all times during

operation; maintain control of the workpiece.

• Take precautions against kickback. Do not permit

anyone to stand or cross in line of cutterhead's rota-

tion. Kickback or thrown debris will travel in this

direction.

• Turn switch off and disconnect power whenever plan-

er is not in use.

• Replace or sharpen blades as they become damaged

or dull.

• Keep planer maintained. Follow maintenance

instructions (See pages 11-14).

DEPTH OF CUT

Refer to Figures 5 and 21, page 20.

The depth of cut is adjusted by the relative positioning

of the table with respect to the blades in the cutterhead.

Table can be raised or lowered using the handwheel. To

adjust depth of cut:

• Loosen table lock knobs.

• Turn handwheel to raise or lower the handwheel.

• Position the table at the desired position.

• Turn the planer key to ON position and press the

start button.

• Feed the lumber from the infeed side.

• Use the scale on the column to measure the depth

of cut.

• To increase depth of cut raise the table: to decrease

depth of cut lower the table.

• Tighten the table lock knobs.

• When planing several pieces of wood, plane all the

lumber with the same set-up to have uniform thick-

ness removed.

• A depth of cut limiter (Key No. 52) is provided to limit

depth of cut to maximum of 0.125" for boards larger

than 8" wide.

Recommended Maximum Depth of Cut:

Hard/Softwood up to 8" wide ................ 0.230"

Hard/Softwood 8" to 20" wide ............... 0.125"

USING DIGITAL SCALE

Refer to Figure 6, page 8.

• Before using scale, wipe down the vertical scale with

a dry, soft cloth. Do not use cleaning solutions. Do

not allow any liquids (such as machine oil) to contact

the body of the digital display. Keep the device clean.

• Data from the digital scale can be input into a com-

puter via the port at the side of the device. Simply

slide off the small port cover (see Figure 6, page 8).
