9.
USE EYE AND EAR PROTECTION. Always wear ANSI approved chemical splash goggles
when working with chemicals. Always wear ANSI approved impact safety goggles at other
times. Wear a full face shield if you are producing metal filings or wood chips. Wear and
ANSI approved dust mask or respirator when working around metal, wood, and chemical
dusts and mists.
DO NOT ABUSE THE POWER CORD. Do not yank it to disconnect it from the
receptacle. Do not carry tools by the cord.
10. DO NOT OVERREACH. Keep proper footing and balance at all times. Do not reach over
or across running machines.
11. MAINTAIN TOOLS WITH CARE. Keep tools sharp and clean for better and safer
performance. Follow instructions for lubricating and changing accessories. Inspect tool
cords periodically and, if damaged, have them repaired by an authorized technician. The
handles must be kept clean, dry, and free from oil and grease at all times.
12. DISCONNECT POWER. Unplug when not in use, before servicing, and when changing
accessories.
13. REMOVE ADJUSTING KEYS AND WRENCHES. Make it a habit to check that keys and
adjusting wrenches are removed from the tool or machine work surface before plugging it
in.
14. AVOID UNINTENTIONAL STARTING. Be sure the switch is in the OFF position when not in
use and before plugging in. Do not carry any tool with your finger on the trigger, whether it
is plugged in or not.
15. OUTDOOR EXTENSIONS CORDS. When the equipment is operated outdoors, use only
extension cords intended or outside use. See chart under “Extension Cords: for the proper
AWG rating depending on the length of the cord(s) being used.
16. STAY ALERT. Watch what you are doing, use common sense. Do not operate any tool
when you are tired.
17. CHECK DAMAGED PARTS. Before using any tool, any part that appears damaged should
be carefully checked to determine that it will operate properly and perform its intended
function. Check for alignment and binding of moving parts; any broken parts or mounting
fixtures; and any other condition that may affect proper operation. Any part that is damaged
should be properly repaired or replaced by a qualified technician. Do not use the tool if any
switch does not turn on and off properly.
18. GUARD AGAINST ELECTRIC SHOCK. Prevent body contact with grounded surfaces
such as pipes, radiators, ranges, and refrigerator enclosures.
19. REPLACEMENT PARTS AND ACCESSORIES. When servicing, use only identical
replacement parts. Use of any other parts will void the warranty. Only use accessories
intended for use with this tool. Approved accessories are available from Harbor Freight
Tools.
20. DO NOT OPERATE TOOL IF UNDER THE INFLUENCE OF ALCOHOL OR DRUGS.
Read warning labels on prescriptions to determine if your judgment or reflexes are
impaired while taking drugs. If there is any doubt, do not operate the tool.

21. REMOVE FOREIGN OBJECTS FORM STOCK. All nails, screws, and all other hardware
must be removed from wood before planing. Never allow planer to come in contact with any
metal when operating. This will chip the blades.
22. DO NOT LEAVE BLADE EXPOSED WHEN NOT IN USE. Never lay planer on its shoe
while cutter head is exposed. Retract cutter head entirely when storing.
23. DO NOT COVER OR ALLOW AIR VENTS TO BECOME BLOCKED. Motor requires
sufficient ventilation to prevent overheating.
24. KEEP ALL GUARDS IN PLACE. Do not operate if a guard is functioning improperly.
25. KEEP CHIP CHUTE CLEAR. Make sure there are no obstructions that would prevent the
ejection of chips. Always unplug tool and let cutterhead reach a complete stop before
clearing out chute.
26. RELEASE TRIGGER IMMEDIATELYAFTER REMOVING CUTTERHEAD FROM STOCK.
Do not leave trigger locked on after lifting. Only use trigger lock when planing for extended
period of time and when cutterhead will be in constant contact with your stock.
GROUNDING INSTRUCTIONS
1. This machine has a three prong plug. The third prong (round) is the ground. Plug the
machine’s cord only into three-prong receptacles. Never cut off the round prong. Cutting off
the ground will result in a safety hazard and void the warranty.
2. If a three-prong receptacle is not available, you may use an adapter. Extending from the
male end of the adapter, you will find a ring connector or wire lead with a ring connector
where the ground (round prong) would be. Remove the center screw of the outlet cover and
put the screw through the ring connector and back into the hole of the outlet cover. Do not
over tighten or you will crack the outlet cover.
VOLTAGE WARNING
Common household current is 110-120 volts. As long as your tool is rated from 110V-120V there
will be no complications using this tool with household receptacles. If your tool is rated 220V-240V
it has a completely different style of plug and must be used with a 220V-240V receptacle. Never try
to plug a 110V-120V tool into a 220V-240V circuit (or vice-versa) or serious complications will
arise, including possible injury to the operator. The plugs and receptacle have completely different
shapes to prevent this from occurring accidentally. Do not modify your plug in any way. If you have
any doubts, call a qualified electrician.

EXTENSION CORDS
Your tool has a three prong plug, therefore you must use a three- prong extension cord. Only use
rounded jacket extension cords listed by the Underwriters Laboratories (UL). If you are using the
tool outdoors, you must use an extension cord rated for outdoor use. This is signified by the letters
“WA” on the jacket.
The extension cord must have a minimum wire size depending on the amperage of the tool and
the length of the extension cord. This size is signified by its AWG (American Wire Gauge) rating.
The smaller the gauge, the greater the cable’s capacity. It does not matter if you are using one
cord, or two or more- the total length is what is used to determine the minimum AWG rating. Every
cord used must meet the AWG rating. Use the chart below to determine what AWG rating is
required for your situation. Cord length is rated in feet.

Always inspect extension cords for any damage. If there are any loose, frayed, or exposed
wires; damaged insulation; or defective connections, the cord must not be used. Harbor Freight
Tools can supply UL listed and outdoor rated cords in multiple AWG rating if needed.

WARNING: CHECK BLADE SETTING AND TIGHTNESS BEFORE INITIAL USE.
OPERATIONS
Basic Procedures
Step 1: Bring cutterhead up to full speed before engaging stock.
Step 2: The TRIGGER (#40) can be locked on using the Trigger Lock Button as shown in
Figure #1. See Safety Warnings and Precautions #26.
Step 3: Use the Rear Handle to gently push the Planer. Do not force. See Figure #1.

Figure 1 — Using the Planer
Step 4: The DEPTH SET KNOB (#36) controls the depth of cut. Turn counterclockwise to
decrease, and clockwise to increase the cutting depth. Note that several light passes
will create a finer finish than one or two deep cuts. See Figure #1.
Step 5: The DEPTH SET KNOB is also used to guide the planer when operating. Apply only light
pressure.

Fence Use and Installation
Step 1: The FENCE (#65) can only be used when edge of stock is flat and at a 90° angle to the
surface being plane.
Step 2: The Fence must be used to engage is Rabbeting Procedures (see below).
Step 3: To install the FENCE, first loosen the front KNOB (#61) by turning it counterclockwise.
(See Figure 2.)

Fence
(#65)
Figure 2 — Using the Fence
Step 4: Insert the fence into the hole as shown in Figure 2.
Step 5: Though the FENCE is shown being installed in the right side, it can be positioned on the
left as well.
Step 6: Set the fence so that it rests against the edge of the stock and so that the cutterhead is
positioned to plane the desired area.
Step 7: Tighten the KNOB by turning clockwise.

Rabbeting
Step 1: Install FENCE as described above
Step 2: Determine the width of the desired rabbet.
Step 3: Using a ruler or other suitable device, set the fence so that only the necessary amount of
the cutterhead will plane the stock.
Step 4: Set the DEPTH KNOB to the desired cutting depth.
Chamfering
Chamfering is a delicate, free-hand operation. Practice on old stock before using on valuable
workpieces. The FENCE must be removed when chamfering.
Step 1: The FRONT FOOT (#32) as a V-groove to aid in this operation. Each side of the
V-groove must rest against the sides of the corner to be chamfered. In other words, the
corner of the stock and the V-groove must fit together.
Step 2: Do not allow cutterhead to engage stock until it has reached full speed.
Step 3: Engage motor and move planer slowly forward so that the cutterhead begins to plane.
Use slightly more pressure on both handles, move the planer very slowly, and keep a
steady hand.
