3General
The surface planers and jointers of the types 334|20, 335|20 and 336|20 were produced by HOKUBEMA Mas-
chinenbau GmbH according to the current state of the art and put into operation as a complete machine. All
legal and normative regulations were complied with.
•The three machine variants differ in their respective planing width:
Type 334|20 (410 mm) / Type 335|20 (510 mm) / Type 336|20 (630 mm)
•The infeed table is equipped with an electromotive chip removal adjustment up to max. 8 mm.
•The outfeed table is equipped with a hollow and pointed joint adjustment.
•All measuring scales are manufactured according to accuracy class 2in accordance with the calibration
regulations.
3.1 Target Group and Previous Experience
This operating manual is intended for the operating and maintenance personnel of the machine. The operating
personnel is to be determined by the operator and must further meet the following requirements:
•Basic technical knowledge (e.g. apprenticeship as carpenter, machine fitter, etc. and/or practice in operat-
ing woodworking machines)
•Reading and understanding these operating and maintenance instructions
In order to acquire the knowledge required to operate this machine, the operator must ensure the following
measures:
•Product training for every operator (also possible external personnel)
•Regular safety instruction
3.2 Requirements for the Operators
•The surface planer & jointer may only be operated by trained personnel who have also read this manual.
•Inspection, maintenance, cleaning and repair may only be performed by technical specialists
with product-specific training and mechanical and/or electrical training.
•Specialists with product-specific training are to be commissioned and held responsible for
planning and checking the work.
•The national protective regulations for employees must be observed .
•The operator is responsible for the safe use of the machine.
•The legal minimum age must be observed.
3.3 Accident Prevention
To avoid accidents, the following rules must be observed for operation:
•Prevent unauthorized persons from gaining access to the machine.
•Keep unauthorized persons away from the danger areas.
•Repeatedly inform present other persons about existing residual risks (see section 4.1.3).
•Conduct and record regular training & instruction for persons who must be in the area of the machine.
•New employees must be trained internally to work on a thickener and this training must be documented.

3.4 General Safety Regulations
In general, the following safety regulations and obligations apply when handling the planer & thicknesser:
•A surface planer & jointer may only be operated in a technically perfect and clean condition.
•It is prohibited to remove, modify or bypass any protective, safety or monitoring equipment.
•It is forbidden to modify or alter the machine without the written approval of the manufacturer / supplier.
•Faults or damage must be reported to the operator immediately, eliminated without delay and repaired if
necessary.
•For repairs, only original spare parts may be used.
•All protective, safety and monitoring devices must be regularly checked and maintained by the operator.
•Only instructed, trained or qualified persons may work on this machine.
•Maintenance work must be carried out and documented in accordance with the maintenance instruc-
tions.
•After maintenance or repair, the machine may only be started with all protective devices fitted. A respon-
sible person must be defined for this purpose, who checks that the guards have been properly installed.
For the operation of a thickness planer, the respective national safety regulations for employees as well as the
national safety and accident prevention regulations apply.

3.5 Structure and Function
•The machine has a heavy, well-shaped construction and meets all the requirements of modern wood pro-
cessing.
•The base gives the machine a perfect stand and smooth running. The smooth front, as well as the stand
retracted at the bottom, allow trouble-free work.
•The tables are heavily ribbed for secure support, and the long version features asymmetrical table lengths
and serrated table lips. The outfeed table is equipped with hollow and pointed joint adjustment. The
height of the infeed table is adjusted by an electric motor to set the chip removal thickness. The chip re-
moval and the setting of the hollow and pointed joint are visualized on a digital indicator.
•The fence has a smooth-running roller guide with an additional support roller on the outfeed table. It can
be quickly adjusted over the entire table width with a practical one-handed lever. This also allows the
fence to be tilted from 0° to 45°.
•The Tersa cutter block installed in the standard model is a dynamically balanced safety four-knife shaft
running in special ball bearings. Other types of cutter blocks are optionally available (see section 15.1).
•The suction nozzle has a diameter of 160 mm and is fixed in the machine.
•The machine is driven by a three-phase motor with mechanical motor brake. It has a central circuit with
push-switch unit and motor protection switch.
•The control panel (with main switch, cutter block switch, brake release switch, height adjustment of the
feed table and digital indicator) is designed to be user-friendly, as it is easily accessible from the operating
side and placed at eye level.
•The guards comply with the regulations of the German Employer's Liability Insurance Association for
Wood.
3.6 Advantages & Special Features of the Machine
The surface planers and jointers of types 334|20 (410 mm planing width), 335|20 (510 mm planing width) and
336|20 (630 mm planing width) are characterized, in addition to their compact and robust steel construction,
by the extremely smooth and quiet running of their dynamically balanced cutter block.
The maintenance-free design of the bearing arrangement with high-performance precision ball bearings guar-
antees long-lasting reliability.
The finely planed cast iron tables with a total length of 2850 mm are mounted vibration-free and ensure a
perfect planing result. The controls for the electromotive height adjustment with digital indicator for the chip
removal setting are functionally arranged.
The machine is suitable for surface planing and jointing, including hollow and pointed joint adjustment at the
outfeed table. The hollow and pointed joint can be precisely adjusted by a handwheel.
Surface planing is possible up to a chip removal of 8 mm.
The working position is ergonomic directly on the cutter block.
The fence, made of a thick-walled, anodized double-chamber profile, can be adjusted smoothly and is infinitely
variable up to 45°. The integrated auxiliary fence can be folded up and down easily and without tools for im-
mediate use.
