Safety instructions

Attention!
The MULE® floor stripper is constructed according to existing safety rules and regulations. These technical precautions should not be removed or changed under any circumstances. Ensure that any user of the machine is fully familiar with the instructions for use before allowing work to start. While operating the machine the following points should also be kept in mind:

1. The floor stripper MULE® should always be operated with all safety covers and technical precautions.
2. During transport, cleaning, repair or maintenance the floor stripper must be disconnected from the mains. This also applies to the changing of tools.
3. Always remove the tool before transporting the machine.
4. Only use tools delivered by CONTEC® .
5. The operator should never leave the machine unattended during operation.
6. Before leaving the machine all rotary parts should be brought to a standstill. The floor stripper must be disconnected from the mains. Make sure that the machine cannot roll or move by itself.
7. The MULE should be switched off immediately if unusual noises or vibrations are detected during the operating of the machinery. A thorough check must be carried out in order to detect the cause.
8. After any maintenance and adjustment all safety covers must be reattached.
9. Ear protectors must be worn.
10. Eye protectors must be worn.
11. Safety shoes with steel caps must be worn.
12. Depending on the type of floor (floor coating) stripping can produce gases/dust. The operator must be held responsible if these generated gases/dust are dangerous and if protection is necessary. Stripping floors containing asbestos is especially dangerous and can cause health problems. Special masks must be worn which keep the breathing air clean. A dust collector must be used and should be equipped with filters suitable for asbestos dust.

The floor must be swept before stripping. Anchor screws and bolts coming out of the floor can be better seen if the floor is clean. If the stripping tool strikes an anchor screw or bolt then serious damage can be caused to the machine or tools.

Maintenance

Changing the blade:
Attention!
Disconnect the power supply before changing the tool. Use work gloves for your own safety. Lock the center weights in position 1 (§ 6.3). Tip the machine until it rests in a stable position. Clean and loosen the screws of the blade mounting (7). Attention! Set the wrench at a position opposite to the blade to avoid injury. Wear gloves! Replace the blade.

Make sure that the blade fits exactly into the support. On normal and hard subfloors the bevel of the blade should show upwards (B). On soft subfloors the bevel should show downwards (A).

Tighten the screws of the blade mounting again.

Operating

The MULE®-Stripper removes any bonded floor covering by using a vibrating knife. The knife is driven by an electric motor (2). The speed is powered by a separate motor (37). The blade drive starts as soon as the machine is switched on and can easily be switched off by pressing the emergency switch (119). The drive unit motor starts by pressing the dead man switch (44) on the handle bar. If the handle bar is pushed forward the drive unit starts to work and the machine starts to move. The drive can be locked in the moving position by stepping on the foot lever (57) at the bottom of the handle bar. The MULE®-Stripper is equipped with a power-on indicator lamp (117). If the lamp does not indicate power-on, use another power socket or check power supply. If a mains power failure occurs during operation, switch the machine on again.

Preparations (Carpets, Coverings)
Before starting work, cut the floor covering into strips of about 25 cm (9.8 in). You cannot work faster if you cut wider strips. To begin, cut one strip crosswise. Then lift the floor covering slightly in order to get the blade underneath it. We recommend that you cut the first strip at right angles to the main working direction. By so doing access to the adjacent strips is made easier. Cut the strips smaller if the floor covering is bonded very securely, e.g. with an epoxy adhesive. The blades are sharpened by the floor pavement. Therefore the blade only has to be changed if it is twisted, rounded or becomes worn. The driving wheels (23) are subject to wear. They have to be changed if necessary.

Adjusting the handle
The height of the handle bar can be adjusted to adapt the machine to the stature of the operator. To adjust the inclination, loosen the two screws (42) at the base of the handle.

Adjusting the weights
The two center weights (103 and 104) can be locked in three different positions.
The locking bolt (111) is situated on the right hand outside weight (102). The bolt must be pulled out before changing the position.

• Pos. 1: The weight is mostly on the rear traction wheels. The wheels don’t slip and the drive is increased. Option for transporting the machine with a crane.
• Pos. 2: Middle position.
• Pos. 3: The weight is mostly on the tool. The tools will not jump up and slide on top of the covering.
