Safety Instructions

General Safety Instructions

Read all the warnings and instructions included with the saw stand or the power tool you intend to mount on it. Failure to observe the safety information and follow instructions may result in electric shock, fire and/or serious injury.

Safety Instructions for Saw Stands

Disconnect the plug from the power source and/or re-move the battery from the power tool before making any adjustments to the power tool or changing ac-cessories. Accidents can occur when power tools are started unintentionally.
Assemble the saw stand properly before mounting the power tool. Correct assembly is important to prevent the risk of collapsing.
Firmly secure the power tool to the saw stand before using it. You may lose control of the power tool if it slips on the saw stand.
Place the saw stand on a firm, flat, horizontal surface. If there is a chance that the saw stand will slip or wobble, the safe and steady machining of the workpiece cannot be guaranteed.
Do not overload the saw stand or climb or stand on it. Overloading or standing on the saw stand can raise its centre of gravity, causing it to tip over.
Ensure that all screws and connecting pieces are tightly fastened during transport and when carrying out work. The holder sets for the power tool must always be securely locked. Loose connections can cause instability and inaccurate sawing.
Only install and remove the power tool when it is in the transport position (for information on the trans-port position, also refer to the operating instructions for the relevant power tool). Otherwise the power tool may have an such unfavourable centre of gravity that you will not be able to hold onto it securely.
Operate the power tool fastened to the holder set only on the saw stand. Without the saw stand, the holder set with the power tool is not secure and can tilt.
Ensure that long and heavy workpieces do not unbalance the saw stand. The free end of long and heavy workpieces must have something placed underneath it or be supported.
When pushing together or pulling apart the saw stand, do not put your fingers near the points of articulation. There is a risk of fingers being crushed.

Symbols
The following symbols may provide you with important information about the use of your saw stand. Please take note of these symbols and their meaning. Knowing what these symbols mean will help you to use your saw stand more effectively and more safely.

Symbols and their meaning

The maximum load-bearing capacity (power tool + workpiece) of the saw stand is 250 kg.

Technical Data

Assembly

Items included
See the list of items included at the start of the

operating manual.
Check to ensure that all the parts listed below have been supplied before assembling the saw stand:

Extra tools required (not included in the delivery):

Open-end spanner (10 mm)

Installing the Saw Stand
Carefully remove all parts included in the delivery from their packaging.
Remove all packing material.

Setting up the saw stand (see figures A1−A2)

Place the saw stand on the floor with legs up.
Press the locking pin (15) in and swivel the leg up until the locking pin audibly engages again.
Repeat this work step with the other three legs.
Rotate the saw stand into the working position.
Make sure that the saw stand is stable and all locking pins have engaged.
A height-adjustable foot (9) helps you to align the saw stand.
Screw the foot in or out until the saw stand is level and all four legs are on the ground.
Installing roller support (see figure B1)
Unscrew the cross-head screw of the roller support (7) with the supplied cross-headed screwdriver (14).
If required, resist the lock nut on the other side of the
roller support with an open-end spanner (10 mm).
Remove the roller support (7).
There are various options as to how the individual rollers can be arranged on the workpiece support using the internal threaded rod.
Arrange the individual parts as required and push the internal threaded rod through the rollers and through the workpiece support (1).
Screw all parts back together.
Installing workpiece support (see figure B2)
Release the locking knobs (3) and pull the table extensions (2) slightly out on both sides of the saw stand.
Push the workpiece supports (1) from left and right respectively into the upper groove of the saw stand or the table extension.
The length stops (8) must point outwards here.
Pull the locking knob (6) to lock the workpiece support.

Preparing the Saw Stand
Preparing holder sets (see figures C1–C4)

To unlock the holder sets (4), press the buttons (16) and open the levers (17) respectively.
Measure the distance x between the assembly holes on your power tool.
Position the holder sets (4) in the centre of the saw stand vand at the appropriate distance x from each other.
Close each lever (17) again. This allows the holder sets to be firmly positioned on the saw stand.
Setting up the saw stand (see figure D)
Bring the power tool into the transport position. Information about the transport position can be found in the operating vinstructions for the corresponding power tool.
Position the movable nuts (18) in the holder sets so that they match the assembly holes on the power tool.
Screw using the supplied socket spanner (14) holder set and power tool with the hexagon screws and washers from the fastening set (19).

Operation

Working Advice
Always hold the workpiece firmly in place, especially long, heavy pieces. Once the workpiece has been cut, the centre of gravity may be displaced, causing the saw stand to tip over.

Do not overload the saw stand. Always observe the maximum load bearing capacity of the saw stand.
Preparing the workpiece support
The free end of long workpieces must have something placed underneath it or be supported.
Adjusting the height of the workpiece support (see figure E)

Place your workpiece on the saw table for the power tool.
Release the locking knob (5) and adjust the height of the broller support (7) so that your workpiece is straight.
Re-tighten this locking knob.
Sawing workpieces of the same length (see figure F)
The length stop (8) can be used for easily sawing workpieces of the same length.
Pull the length stop (8) up until it engages.
Position the workpiece support (1) at the required distance from the saw blade of the power tool.
To insert the length stop (8), tilt the length stop in and press it fully down.
Extending the saw stand (see figure G)
The saw stand can be extended on both sides.
To stabilise the saw stand when machining long and heavy workpieces, you can support the table extension (2) with a support leg (13).
Place your long workpiece on the saw table for the power tool.
If necessary, loosen the corresponding locking knob (3) and pull the table extension (2) outwards until it reaches the required length.
Re-tighten this locking knob.

Installation of Accessories

Support leg for supporting the table extension (see figure H)
To stabilise the saw stand when machining long and heavy workpieces, you can support the table extension (2) with a support leg (13).
You can fasten the support leg (13) either left or right of the saw stand.

Release the locking knob (3) and pull the table extension (2) that you want to be supported slightly out.
Push the screw head of the support leg (13) into the lower groove of the table extension (2).
Turn the support leg (13) firmly.
Screw the height adjustment of the support leg (13) in or out until the saw stand is level again.

Transport wheels and stop for quickly changing the operation site (see figures I1−I2)
The transport wheels (12) allow you to transport the saw mstand to another operation site, without having to remove the stationary saw installed on it.

You can fasten the transport wheels (12) either left or right of the saw stand.

Use the fastening set (20) for installation.
Place the saw stand on the floor with folded legs up.
Screw the transport wheels to the saw stand at the required place using the four screws and nuts.
Use the supplied hex key (14) for this.
Rotate the saw stand into the working position.
On the side of the saw stand to which the transport wheels are fastened, release the locking knob (3) and pull the table extension (2) slightly out.
Push the transport stop (11) into the upper groove of the saw stand and move the transport stop up to the holder set (4).
Tighten the hexagon screw in the stop with the supplied socket spanner (14).
The holder set with installed power tool can now no longer slip during transport.

Transport (see figure J)
You must fold up the saw stand for transport.

If a support leg (13) is installed, remove it.
Push the table extensions (2) fully in.
Swivel all legs in (press locking pin (15) in; swivel leg in until the locking pin audibly engages again).
Reach into the handle recess and lift the saw stand.
