1. Safety and Warning Labels
A number of important warning labels have been attached to this handheld power planer for your information
and protection.
For your own safety, please take a moment to locate and read all warning labels before operating this machine.
If a label has been removed, defaced or is illegible, please contact Hoffmann Machine Company, Inc. to request
a free replacement. NEVER REMOVE ANY SAFETY OR WARNING LABEL!
2. General Machine Description
The Hoffmann BH 556 Lipping Planer is a handheld planing machine. It is designed solely for flush planing of
applied solid wood and laminate edges.
The machine can be used on solid hard and softwood edges as well as veneer and laminate edgebanding
materials.
Depending on the material being planed and the feed rate, up to 3mm = 1/8” material can be removed in one
pass.
The machine uses the panel surface as reference for the planing operation, which explains why imperfections,
high or low spots, etc. in the panel could adversely effect the planing result. Unsatisfactory results due to poor
panel surfaces, insufficient preparation or improper operation are not covered under our warranty and are not
grounds for replacement or refund.
USE OF THIS MACHINE FOR ANY OTHER OPERATION IS DANGEROUS AND WILL VOID THE WARRANTY.The
manufacturer cannot be held liable if the machine is used for any operations other than outlined in this manual.
3. Operator Training
The Hoffmann BH 556 Lipping Planer is to be operated, maintained and repaired only by properly trained and
qualified personnel. It is imperative that the operator has carefully read and understood these operating
instructions, and that he or she is aware of all potential risks resulting from operating this machine.
For proper planing results, the operator should take the time to practice the handling and use of the machine on
spare materials before using the machine on actual production parts.
All applicable safety procedures and rules, including but not limited to all OSHA Rules and Regulations, are to
be adhered to.
Any unauthorized modification or alteration to this machine by the operator or owner will immediately void the
machine warranty. The manufacturer cannot be held liable if the machine is used for any operations other than
outlined in this manual or if the machine is modified or altered.
If the operator does not posses sufficient English language skills to completely understand all sections of this
manual, especially the sections on Warning Labels and Safety Rules, it is the responsibility of the purchaser to
retain a qualified translator to translate this entire manual.

4. Safety Rules
Read and understand these safety rules before operating this machine!
1. Always disconnect the machine from the electrical power supply before attempting any
adjustment, repair or maintenance procedure (change of blades, depth-of-cut adjustment,
removal of wood dust, etc.).
2. Always wear eye and ear protection as well as a respirator suitable for wood dust.
3. Always use suitable dust collection system. Duct must be properly connected to dust extraction
port.
4. Never operate the machine without first installing the side handle.
5. Always use both hands to operate the machine.
6. Small workpieces, panels, etc. must be securely fastened to work table before planing.
7. Always check workpiece for nails, screws, stones or other embedded material. All foreign
material must be removed prior to planing.
8. Keep all electrical power tools out of reach of children at all times.
9. Do not allow power cord to lie on floor, in the way of passing personnel or the machine operator.
It will cause a trip hazard.
10. Make sure the electrical outlet is properly grounded.
Never remove the grounding prong from the power plug!
11. Use only grounded extension cords, minimum size: 14-gauge (AWG).
12. Remove or confine loose hair, clothing and jewelry to avoid entanglement.
13. Avoid a dangerous environment. Do not expose electrical equipment to rain. Do not use in
presence of flammable liquids or gases.
14. Keep the area around the machine clean and free from scrap, sawdust, wood chips, oil and
grease to avoid the danger of slipping.
15. Use only sharp and flawless original Hoffmann carbide blades.
16. Replace worn blades immediately. Always replace blades in sets of two.
17. Check the machine upon receipt as well as before every use for improper functioning and worn
or damaged parts. Make sure the blades are securely installed.
18. Always check the proper function of the cutter head guard before operating the machine. Never
operate this machine with damaged or missing blade guard!
19. Broken or defective parts must not be used until replaced or repaired by a qualified technician.
20. When interrupting work or upon leaving the area, machine must be disconnected to avoid
unauthorized operation.
21. Only trained and qualified personnel must be allowed to use machine.

5. Operation
1. Initial Set-Up
DISCONNECT ELECTRICAL POWER SUPPLY BEFORE ATTEMPTING ANY ADJUSTMENT OR MAINTENANCE WORK!
With a straight edge, check if blades are in line with base plate. Use two small Allen screws in knife
clamping plate to adjust blade up or down, if necessary. Blades should be in-line with base plate and
project not more than 1.1mm above cutterhead body. (see drawing B)
Attach side handle (1) on cutterhead housing.
2. Operation
a) Set machine on panel and connect power supply.
b) Hold machine with main handle (2) and lift cutterhead off the panel with side handle (1).
Cutterhead must be clear off panel before machine is switched on!
c) Switch on machine.
d) Using two fingers, pull back blade guard (3) to expose rotating cutterhead.
e) SLOWLY lower machine onto panel.
f) To stop, lift machine off panel.
g) Release power switch and blade guard.
h) Set down machine only after cutterhead has come to a complete stop.

3. Adjusting cutterhead to panel surface
a) Check with straight edge to assure cutterhead is set higher than base plate before continuing.
b) To adjust the cutterhead setting, switch on the machine and set it on a piece of flat panel (panel
does not need to have wood edge attached).
Caution: Make sure panel is secured to table with clamps, screws, etc. If cutterhead setting is
incorrect, an unsecured panel could be thrown off the table possible causing an injury!
c) SLOWLY turn the front adjustment knob (4) to lower the rotating cutterhead onto the panel.
Turning the knob clockwise will raise the cutterhead off of the panel, turning it counterclockwise
will lower the cutterhead onto the panel. (A coin may be used to turn the inner portion of the
knob.)
The knob is equipped with a built-in spring to produce a ratchet action. Each “click” of the ratchet
raises or lowers the cutterhead approx. 1/10mm – 4/1000”.
d) When adjusted correctly, the blades will slightly touch the panel without leaving any marks.
4. Feed rate
The maximum feed rate depends on various factors including depth of cut (how much material is
removed), width of cut (how wide the edge is), condition of blades, material being planed, etc.
While the BH 556 can remove up to 1/8” of material in one pass, it is recommended that the wooden
edge be glued as precise as possible, generally about 1/16” higher than the panel.
A power plane can only produce a clean cut when it is operated at full RPM!

5. Maintenance
The BH 556 is equipped with solid carbide blades, which are indexed and reversible.
The blades cannot be sharpened and must be replaced with Original Hoffmann Replacement Blades
when dull.
Always replace blades in pairs.
Caution: Check condition of blades before every use and replace dull or worn blades
immediately. Using dull blades results in rough surfaces on the finished product and could
cause motor damage.
Blade Change
a) Disconnect electrical power supply from machine.
b) Pull back pivoting blade guard.
c) Loosen set screws (60) in cutterhead with 8mm wrench.
d) Slide blades sideways out of holder.
e) Clean blade holder and screws and remove all wood residue.
f) Install new blades. Important: The indentation in the knife set plate must be properly aligned with
the knife clamping plate.
The ridge in the knife set plate must rest in the groove in the blade back.
g) Blade assembly must be centered in cutterhead.
h) Tighten the locking screws with the enclosed 8mm wrench.
i) If set properly, blades should extend 1.1mm past cutterhead body.
Brush Change
Always replace brushes in pairs. Use only Original Hoffmann Parts.
a) Remove screws (29) and motor cover (30).
b) Remove old brushes and insert new ones (31) in same manner.
c) Replace motor cover (30) and secure with screws (29).
6. Cleaning of Machine
Clean machine regularly with compressed air. Keep swivel guard in good operating order. Remove
glue residue immediately from base plate.
Never use paint thinner or alcohol to clean machine – damage may occur.
