Transport and start up

Transport and installation
The machine is designed to operate in closed rooms and must be bolted stable on a firm and levelled table surface

Assembly

• If you notice transport damage while unpacking, notify your supplier immediately. Do not operate the machine!
• Dispose of the packing in an environmentally friendly manner.
• Clean all rust protected surfaces with a mild solvent.
• Screw the handle (A, Fig 1) into the pinion shaft (B, Fig 1) and tighten (C, Fig 1).
• Use the handle to raise the machine head to the up position. The handle is spring loaded and can be repositioned by pulling the handle away from the head, and turned to the desired angle.
• Press the gas spring onto the two fittings (D and E).
• Attach the MDF table to the base using two screws (A, Fig 2).
• Insert bar of fence assembly (B) through the hole in the column.
• Use the indexable knob (C) to adjust the fence assembly.
• Attach the hold down (D) to the vertical post using locking handle (E).
• Mains connection and any extension cords used must comply with applicable regulations.
• The mains voltage must comply with the information on the machine licence plate.
• The mains connection must have a 10 A surge-proof fuse.
• Only use power cords marked H07RN-F.
• Connections and repairs to the electrical equipment may only be carried out by qualified electricians

Dust collection

• Use a suitable dust collection and filtration system to avoid a high dust concentration in the air.
• Dust the machine down after each use and as necessary

Starting operation
You can start the machine with the green on button. The red button on the main switch stops the machine.

Machine operation

Set the depth stop rod (B, Fig 3) to the required depth of cut.

Adjust the fence.

• Adjust the hold down so it touches the top of the workpiece and allows it to slide left or right.
• Turn on the machine and feed chisel and bit steadily into the workpiece by pulling down the operating handle.

NOTE:

• The rate of feed must be fast enough to prevent burning at the tip of the drill bit, but not so fast as to cause the machine to stall.
• The different rates of feed for different woods must be learned by experience.
• After the first cut, the workpiece is moved. The direction of movement
• When cutting deep mortises, make the cut in several stages of approx. 25mm each, to allow chips to clear.
• To prevent breakout at the back of the workpiece when cutting through mortises, use a piece of scrap material under the workpiece as support.

Warning:

• Make sure the machine is attached to a firm and stable support surface, to prevent it from tipping during operation. Four holes in the base are supplied for this purpose.
• Always keep your hands well clear of the rotating bit.
• Always close the chuck cover before you start the machine.
• Support long workpieces with helping roller stands.

Setup and adjustments

General note:
Setup and adjustment work may only be carried out after the machine is protected against accidental starting by pulling the mains plug.

Installing chisel and bit

• Disconnect the machine from the power source (unplug).
• Open the chuck access doors on both sides of the head.
• Insert the chisel bushing (3, Fig 5) with the hole facing forward into the head.
• Insert chisel and bit together.
• Tighten the screw (2) just enough to hold the chisel (4) in place.

NOTE:

• The slot in the chisel should face to the right or left side only. The opening will allow chips to escape during operation.

• Push the chisel up as far as possible into the head. Then lower the chisel 1,5 to 4mm, depending on the type of wood being worked. Tighten the screw to hold the chisel in place.

• Push the bit up through the chisel opening as far as it will go.

• Lock the drill bit in place with the chuck key.

• Loosen the screw and push the chisel up against the bushing and tighten the screw. This should provide the proper distance between the points of the chisel and the bit.
  NOTE : The chisel should be adjusted parallel. Use the workpiece as a gauge (Fig 6).

• Close the chuck access doors before starting the machine

Using bits with shorter shanks:

• It will be necessary to attach the spindle extension.
• Place a 10mm open spanner on the motor spindle and use the chuck key to unscrew the chuck.
• Attach the spindle extension to the chuck and reinstall

180° Head rotation

• Remove the three hex socket cap screws at the base and rotate head and column 180°.
• Doing this will enable you to outboard mortise taller items.

Sharpening chisel and bit:

• The chisel and bit should be kept sharp for best performance.
• Sharpen the bit by using a small file, following the original shape of the bit.
• File the inside edge of the spur (A, Fig7), the sides of the centre point (B) and the cutting edge inwards toward the flute of the bit (C).
• Do not file the outside edges of the spur as this will affect the diameter of the bit.
• Sharpen the chisel on the cutting edge inside only.

Maintenance and inspection

General notes:

• Maintenance, cleaning and repair work may only be carried out after the machine is protected against accidental starting by pulling the mains plug.
• The mortise requires only minor maintenance, such a lubrication, routine adjustments and sharpening of chisel and bit.
• Clean the machine regularly.
• Defective safety devices must be replaced immediately.
• Repair and maintenance work on the electrical system may only be carried out by a qualified electrician

Troubleshooting

The motor doesn’t start

No electricity check mains and fuse.
Defective switch, motor or cord-consult an electrician.

Chisel clogged with chips

Clearance chisel to bit not enough set bit 1,5 to 4mm below chisel.
chips cannot clear the chiselobserve chisel slot and the working order

Burned Wood

• Feed too slow increases feed rate.
• Worn chisel or bit sharpen chisel and bit.
