Technical data

Noise parameters acc. to EN ISO 3744
The indicated rates are emission rates and do not correspond with safe working rates. Although there is a correlation between emission and immission levels, it is not sure whether reliable precautions are necessary or not.
The following factors can influence the present immission level at the working place:
Time of impact, property of working room, other noise sources (for instance, number of machines and other neighboring activities.
The reliable working place rates can also vary from one country to another.
Yet this information should enable the user to perform a better evaluation of the dangers and risks,
Acoustic power level in dB Idling
LWA = 93 dB(A) with thickness Idling
LWA =92 dB(A) with surfacing Finishing
LWA = 98 dB(A) with thickness Finishing
LWA = 99 dB(A) with surfacing
Acoustic pressure level at working place in dB Idling
LWA = 78 dB(A) with thickness Idling
LWA = 82 dB(A) with surfacing Finishing
LWA = 83 dB(A) with thickness Finishing
LWA = 91 dB(A) with surfacing A measuring uncertainty coefficient (K = 3 dB) applies to the values listed above.
Dust emission parameters
The dust emission parameters measured according to the principles for measuring dust emissions (concentration parameters) for woodworking machines specified by the German wood professional committee are below 2 mg/m³. Dust emissions can therefore be continuously kept within the range allowed under currently valid German regulations by connecting the machine to a vacuum exhaust system with an airflow speed of at least 20 m/s. Depending on the particular type of workpiece, the stress values of the manufacturer must be observed.

Height adjustment is done with the star grip J screw fitted to the left side of the machine. After releasing the star grip screw K, the cutter block guard can be moved to the
side and the correct planing width set. Press the guard down again to fix it in the right position, and tighten the handles.
Surfacing:
The amount of chip removal is set by means L of the scale M on the front side of the tabletop M. The best surface is obtained at a planing depth between 0.5 and 1.5 mm.
Warning:
The part of the cutter block not used must by covered by the guard. The working position is in front of the machine at the side of the infeed table. Put the fingers of both hands on top of the workpiece. Do not hold the workpiece edges. The workpieces to be planned must lie firmly on the table so they can be guided safely. For short workpieces use a feed stick.
Thickness:

Following the scale and using the handle O on the spindle, set the thicknessing table to the desired height.
1rotation = 3 mm.
Narrow wood is introduced in the center.
When thick, the table must be treated with oil at regular intervals. After a long period of use, or when planning humid wood, it can happen that the workpiece is not further pulled in.

Warning:
In case of a defect, switch off the machine at once. Do not remove any chips or splinters from the tables while the machine is running. Work pieces below 250 mm may not be planed.
Changing the knives (Fig. 11)

Put the main switch of the machine to OFF position.
Pull the power supply plug from the socket.
Block the cutter block guard in the lifted position.
Release and remove the four knife clamping screws.
Lift the knives and knife support from the cutter block.
Remove the chips and any resin from the cutter block
and knife support.
Place new knives into the cutter block and fix them with the rectangle slots in both screw heads. (With these two screws, height adjustment of the knife is done.)
Place the knife support onto the knife.
Slightly tighten the four clamping bolts.
Repeat these actions for the second knife.
Then adjust the planer/thicknesser knives exactly with the output table. Use a ruler that you put onto the output table.
With the two set screws, the knife can be adjusted for height.
By turning the cutter block and using the ruler, you can see the height adjustment.
The knife is exactly set when the ruler is moved by the knives not higher than 3 mm.
After a successful knife setting, all clamping screws must be tightened (8.4 N/m).

Please mind:

Sharp planer/thicknesser knives guarantee a clean planing surface and put less stress on the motor.
After three grinding actions, a maximum material removal of 3 x 0.05 mm may not be exceeded.
The planer/thicknesser blades used on this machine are not suitable for rebating and dovetailing.
Finally, lower the cutter block guard again onto the table. Cover the cutter block and block it with the star grip screw.

Installation

Make sure there is sufficient space for handling the workpiece over the whole length without the operator (or another person) having to stand in line with the work
piece.
Using bolts, washers, and hexagon nuts (not supplied with the machine), the planer/thicknesser can be bolted to a workbench.
The planing machine must be bolted onto a firm, level surface.
The machine may not tilt, and the table must be aligned.

Machine setting up and functions

The electric planer/thicknesser is transportable. It is powered by a single- phase motor and is double-insulated. It has been designed for planing wood, and it features a rational construction, easy operation, and high efficiency.

Maintenance

Always pull the power supply plug before doing any servicing work. Having finished the work, put the cutter block guard in the operating position again.
Machine care
The planer/thicknesser requires little maintenance. The ball bearings are permanently lubricated. After approx. ten operating hours, lubrication of the following parts is recommended:

Bearing of the infeed and output roller
Bearing of pulley and sprocket
The threaded spindle for height adjustment of the thicknessing table may only be treated with a dry lubricant agent. The table surfaces as well as the infeed and output rollers must always be kept free from resin.
Regularly clean infeed and output rollers.
In order to avoid overheating of the motor, regularly check the air openings for any dust sticking on.
After a longer period of use, it is recommended to have the machine checked by an authorized dealer service.

Tool care:

Cutter blocks, clamping devices, knife supports and knives must be regularly cleaned from resin, as a clean tool improves the planing quality. To this purpose, clamping devices, knife supports, and knives can be put in a common resin remover for 24 hours.
Resin from aluminum tools may only be removed with cleaning liquids not being aggressive to this type of metal.

Attention:
In case of a bad condition of the electrical system, the performance can drop for a short period of time. Ask a specialist.
Electrical connection
The electric motor installed is completely wired and ready for operation. The connection meets the requirements of the
German standards VDE and DIN. The connection to the electric power supply to be affected by the customer as well as the extension cable must also meet these requirements. Connection and repair work on the electrical installation may be carried out by a qualified electrician only.
Important hints:
The electric motor has been designed for operating mode S6 / 40 %.
Defective electrical connection cables:
Electrical connection cables often suffer insulation damage. Possible causes are:

Pinch points when connection cables are run through window or door gaps.
Kinks resulting from incorrect attachment or laying of the connection cable.
Cuts resulting from running over the connecting cable.
Insulation damage resulting from forcefully pulling out of the wall socket.
Cracks through the aging of insulation.

Such defective electrical connection cables must not be used as the insulation damage makes them extremely hazardous. Check electrical connection cables regularly for damage. Make sure the cable is disconnected from the mains when checking. Electrical connection cables must comply with the regulations VDE and DIN. Only use cables marked „HO 7 RNF“. This is a binding regulation. Single-phase motor, Fig. 12
