3.1 Conversions and Modifications of the Guard
Conversions and modifications to the bridge guard are strictly prohibited for safety reasons. This will invalidate the CE declaration of conformity! The manufacturer is not liable for any resulting damage. The risk for this is borne solely by the operator/user.

3.2 Dimensions

Fixing on the Machine

Before the bridge guard can be attached to the machine, the machine manufacturer must expressly authorize the attachment of this bridge guard type to the intended machine.

In addition, the intended fixing point of the bridge guard on the machine must be discussed with the manufacturer.
Depending on the fixing point specified by the machine manufacturer, the guard must be fixed as follows:
With M8 through bolts or bolts supplied with the machine or M8 hexagonal bolts screwed into appropriately drilled threaded or through holes. For required drilling diameters see ⇒ Figure 2.

Adjusting the Bridge Guard

After mounting, the bridge guard must be adjusted according to the safety requirements.

Distance to workpiece via grub screws (K):

Figure 3: Adjustment (K)

In the initial position and over the entire adjustment range, the long side of the guard must not be more than 2 mm from the upper workpiece surface on the infeed table side and 3 mm on the outfeed side.
This adjustment is made using the screws (K).

Parallelism to cutter block via fixing screws (H):

Figure 4: Adjustment (H)

Use an SW5 Allen key to tighten the two M8 fixing screws (H) for the bridge support on the underside. The bridge must be parallel to the cutter block. Otherwise, loosen both screws (H), correct the parallelism and tighten the screws again.

Bend compensation via grub screws (K): K

• Adjust the fence to the maximum working width so that the bridge rests against the fence and the wheels are in a vertical position. Then lock the bridge in its support.
• In this state, the front area (D1) of the bridge must be 3 – 4 millimeters higher to the table than the rear area (D2) at the wheels (see ⇒ Figure 5). The adjustment for this is also made using the grub screws (K) shown in ⇒ Figure 3.

This is necessary to compensate for the bending of the bridge during lifting when feeding the workpiece forward.

Stroke and damping via screws (M) and (N):

• The stroke adjustment (up to a maximum of 75 mm) of the bridge in relation to the table is done with the screw (M) shown in ⇒ Figure 6. Adjust the damping of the bridge with the screw (N):
• To do this, lift the bridge manually from the table and let it fall. If it drops too abruptly or stops before it is at table height, adjust the balance spring setting with screw (N).
  The screw is accessed through the opening (5) shown  in ⇒ Figure 7.
  – Turn screw (N) clockwise less →Spring thrust decreases
  – Counterclockwise → Spring thrust increases (more damping)

Note: This setting may also be necessary in the event of major changes or fluctuations in the room temperature.

Safety

The following safety instructions refer explicitly to the TX MATIC planer bridge guard. For safe working with the bridge guard, all safety instructions in the operating manual of your machine must also be observed.

7.1 Residual Risks
The TX MATIX bridge guard corresponds to the latest state of the art and has been manufactured in accordance with the recognized technical safety regulations. Nevertheless, due to the design determined by the intended use of the machine/protective equipment, the following residual risks can still occur even when used as intended and despite compliance with all relevant safety regulations:

| Danger of clothing being drawn in by moving and rotating machine parts or tools.
---|---
| Danger of crushing on workpiece guides and moving machine parts.
| Risk of injury from flying tool parts in the event of tool breakage.
Therefore, generally wear protective goggles.
| Risk of injury from flying workpiece parts and chips, splinters and dust coming out of the machine. Therefore, generally wear protective goggles.
| Increased noise emission. Therefore always wear hearing protection.
| Increased dust emission. Use an extraction unit and/or wear a dust mask.

7.2 Safe Operation
The TX MATIC planning protection device automatically adapts to the conditions of the respective workpiece machining and is also very easy to operate.
The wheel unit (3) at the end of the aluminium bridge (see⇒ Figure 7) can be turned into the vertical, horizontal and 45° position.
In the horizontal position, it can also be folded down by 180°.

Vertical position:

• By positioning the wheels in the vertical position (see ⇒ Figure 8) the bridge stroke is carried out automatically up to a maximum height of 75 mm by  the workpiece feed.
• After machining, the bridge automatically reaches the level of the tabletop.

Horizontal position:
The four sides of a workpiece up to a maximum of 100 x 100 mm can be machined by placing the workpiece against the fence with the wheels in horizontal position without pre-setting.

• When feeding the workpiece against the fence, the bridge moves away from the fence up to max. 100 mm (see ⇒ Figure 9). After machining, the bridge automatically returns to its initial position.

Inclined 45° position:
In addition, the 45° position of the wheels at the 45° inclined fence can be used for beveling and chamfering (see ⇒ Figure 13).

7.2.1 Safe Position of the Hands when Feeding the Workpiece
The following figures show the correct position of the hands for the respective machining operations:

Handling during Knife Change

The knife change must generally be carried out in accordance with the operating instructions of your machine. With regard to the bridge guard, please also follow the instructions below

8.1 Changing the Knives from Above
Pull the TX MATIC bridge guard forward as far as it will go and change the planning knives according to the manufacturer’s instructions and the operating instructions for your machine.

8.2 Changing the Knives from the Front
Set the TX MATIC bridge guard to its uppermost position (75 mm above the table) and change the planning knives according to the manufacturer’s instructions and the operating instructions of your machine.

8.3 After Changing the Knives
After changing the knife, return the guard to its protective position so that the entire cutter block is covered.

Maintenance and Care

Switch off the machine during maintenance and repair work and secure the main switch against unauthorised restarting (e.g. with a padlock)!

• Always make sure that the bridge guard is fully functional.
• Always keep the moving parts running smoothly.
• Clean the bridge guard regularly.
• Replace any damaged parts immediately.
• Regularly check the tightness of the fastening screws to the guard.
• Always completely cover the cutter block with the bridge guard after work.

Scrapping and Disposal

When scrapping the bridge guard, the current EU regulations or the respective regulations and laws of the country of operation, which are prescribed for proper dismantling and disposal, must be complied with.
The aim is to dismantle all materials and components properly, to recycle recyclable parts and to dispose of non-recyclable components in the most environmentally friendly way  possible.

• Plastic parts and other non-metal components must be dismantled and recycled or disposed of separately.
• Dismantle all metal parts of the guard and sort them according to material type (steel, aluminium). Metals can be melted down and recycled.
