Safety Warnings and Precautions
WARNING: When using tool, basic safety precautions should always be followed to
reduce the risk of personal injury and damage to equipment.
Read all instructions before using this tool!
1. Keep work area clean. Cluttered areas invite injuries.
2. Observe work area conditions. Do not use tools in damp or wet locations. Don’t
expose to rain. Keep work area well lighted.
3. Keep children away. Children must never be allowed in the work area. Do not let
them handle tools.
4. Store idle equipment. When not in use, tools must be stored in a dry location to
inhibit rust. Always lock up tools and keep out of reach of children.
5. Use the right tool for the job. Do not attempt to force a small tool or attachment to
do the work of a larger industrial tool. There are certain applications for which this tool
was designed. It will do the job better and more safely at the rate for which it was
intended. Do not modify this tool and do not use this tool for a purpose for which it
was not intended.
6. Dress properly. Do not wear loose clothing or jewelry as they can be caught in
moving parts. Protective, electrically non-conductive clothes and non-skid footwear
are recommended when working. Wear restrictive hair covering to contain long hair.
7. Use eye protection. Always wear ANSI approved impact safety goggles. Wear a full
face shield if you are producing metal filings or wood chips. Wear an ANSI approved
dust mask or respirator when working around metal, wood, and chemical dusts and
mists.

9. Maintain tools with care. Keep tools sharp and clean for better and safer
performance. Follow instructions for lubricating and changing accessories. The
handle must be kept clean, dry, and free from oil and grease at all times.
10. Stay alert. Watch what you are doing, use common sense. Do not operate any tool
when you are tired.
11. Take caution as some woods contain preservatives such as copper chromium
arsenate (CCA) which can be toxic. When cutting these materials extra care should
be taken to avoid inhalation and minimize skin contact.
12. Check for 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 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.
13. 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.
14. Do not operate tool if under the influence of alcohol or drugs. Read warning
labels if taking prescription medicine to determine if your judgment or reflexes are
impaired while taking drugs. If there is any doubt, do not operate the tool.
15. Maintenance. During periods of storage, coat the bare metal surfaces with light oil to
inhibit rust.
Warning: The warnings, cautions, and instructions discussed in this instruction
manual cannot cover all possible conditions and situations that may occur. It must be
understood by the operator that common sense and caution are factors which cannot
be built into this product, but must be supplied by the operator.

Operation
Refer to the Assembly Drawing on page 5 and FIGURE 1 below.
Note: The front blade (fillister) is stationary and the rear blade is movable and replaceable.
1. To change or replace Blades, turn the Blade Removal Knob (see below) counterclockwise
and lift off the blade holder (see below). Set the Blade in so that it fits over the set screw and
is properly aligned. Replace the Blade Holder and tighten the Blade Removal Knob.
2. Adjust the amount of blade you want to contact the workpiece by pressing the Blade
Adjustment lever side to side (see Assembly Drawing on page 5).

3. There are two fences. To adjust the Depth Gauge Fence, loosen the Lock Screw and move
the Fence up or down to determine the depth you cut into the wood (see Assembly Drawing
on page 5). To assemble the Fence located on the left side of the tool, first thread on the Steel
Rod into the left side of tool’s housing. The Fence slides over the end of the Steel Rod and is
locked in place by the Fence Adjustment knob. To adjust this Fence (determines width of
cutting area), loosen the Fence Adjuster knob and move the Fence either closer or further
from the body of the Planer. With the Fence in the desired position, secure it in place by
tightening the Fence Adjuster knob.
4. Make sure the workpiece is securely fastened down.
Note: If you are using the front blade for bullnosing (See Assembly Drawing on page 5), make
sure the rear blade is adjusted up so it doesn’t contact the workpiece.
5. Do not force the Plane or press down on it. Move it forward, taking off a little wood at a
time. If the Plane does not move forward easily, retract the Blade more as explained in step
2 above.
