 For further safety instructions, please refer to the enclosure.

 Electrical Connection

Before starting the machine check the correspondence between voltage and frequency according to the data mentioned on the identification plate. Voltage differences from + 6 % and – 10 % are allowed. The wall chaser is made in protection class II. Only use extension cables with a sufficient cross- section. A cross-section which is too small could cause a considerable drop in performance and an overheating of machine and cable.
The tool is equipped with a start-up speed limiter to prevent that swift automatic circuit breakers are unintentionally triggered.

Recommended minimum cross sections and maximum cable lengths:

Mains voltage                          Cross section in sq. mm
1.5                    2.5
230V                                               30M                   50M

Switching on and off

The wall chaser HCE150 is equipped with a lock-off button against
unintentional switch-on. Switching-on: push the on/off switchforward (1) and then down (2) Switching-off: release the on/off switch

 Instructions for Use

Exercise caution when cutting slots in supporting walls; see section “Information on structural calculations”. Do not strain the machine so heavily that it comes to a standstill.
Only use the wall chaser for dry cutting. Adjust the cutting depth see section “Pre-selection the Cutting Depth”. To compensate inaccuracies that occur when breaking away the fin, the cutting depth must be set approx. 3 mm deeper than the requested slot depth. Place the machine with the front roll (cover) on the surface to be worked. Switch on the machine and slowly lower and plunge the cutting unit into the material.
Guide the machine with both handles, applying moderate feed, suited to the material being worked with. The wall chaser must always work in an up-grinding motion (sliding cut). Otherwise, the danger exists of it being pushed uncontrolled out of the cut.

Remove the remaining fin of the material with a break-out tool or a chiselling hammer. Curved cuts are not possible, as the diamond cutting discs could jam in the material.
When breaking through walls, e. g. with a rotary hammer, most of the chipping- off of the surface material can be avoided by first cutting in a slot with maximum cutting depth. For cutting expecially hard material, e. g. concrete with high pebble content, the diamond cutting disc can overheat and become damaged as a result. This is clearly indicated by circular sparking, rotating with the diamond cutting disc. In this case, interrupt the cutting process and allow the diamond cutting disc to cool by running the machine for a short time with no load. Noticeable decreasing work progress and circular sparking are indications of a blunt diamond cutting disc. Briefly cutting into abrasive material (e. g. lime-sand brick or a diamond-sharpeningstone) can re-sharpen the disc again.

Pre-selection of the Cutting Depth

Set the desired cutting depth on the scale by turning the guard and set the cutting depth on the scale then close the quick-release lever. The quick- release lever must always be firmly closed when working.

 Changing the Diamond Cutting Discs

The Cutting discs, spacer discs and the flange nut might heat up enormously during operation. You could burn your hands or get cut or ripped by the segments. Therefore, always use protective gloves when changing the grinding wheel. Before any work on the tool, disconnect the plug from the mains!

Attention

Disconnect the power plug before carrying out any work on the device!

Press the spindle lock button to lock the work spindle.
Actuate the spindle lock button only when the work spindle is at a standstill.
Otherwise, the machine may become damaged.

Open the clamping screw with the face spanner and remove the diamond cutting discs as well as the spacer discs from the work spindle. Clean the work spindle and all parts to be mounted. Pre-selection of the Groove Width: The groove width results from the number and thickness of the spacer discs between the two diamond cutting discs and the cutting width of the diamond cutting discs.
The grove width is calculated as follows: groove width = Thickness of the spacer discs + width of the diamond cutting discs. Thickness of the spacer discs: 2, 3, 4, 5, 10 and 17 mm.

First the wheel flange has to be mounted on the work spindle (see arrow).
The wheel flange with its driving must have a correct seat on the work spindle. Then mount one of the two diamond cutting discs.
After that put the spacer discs and the second diamond cutting disc according to the required groove width on the work spindle.

Press the spindle lock button to lock the work spindle (see arrow – Fig.3).
Screw on the clamping screw and tighten it with the face spanner (see Fig.4).
Instructions for assembly:

• Regardless of the requested grove width, all spacer discs provided must always be mounted. Otherwise, the diamond cutting disc can become loose during operation and lead to injuries.
• At least one spacer disc must be mounted between two diamond cutting discs.
• When mounting the diamond cutting discs, ensure that the direction of rotation arrows on the diamond cuttingdisc match with the rotation direction of the machine (see direction of rotation arrow on the protective hood).
• Always replace the diamond cutting discs in pairs.
• Use only original accessory!
• The wall chaser is in power and speed optimal adjusted to the TYROLIT-diamond cutting discs. Thus you reach the best work result in consideration of the material to  be worked on (see accessories).

In order to check whether the spindle stop is released before you switch on the tool, turn the spindle slightly. Let the machine run for a short period of time and in a safe position. If the  machine does not run easily, stop working immediately.

Information on Structural Calculations

Slots in supporting walls are subject to the Standard DIN 1053 part 1, or country- specific regulations. These regulations are to be observed under all circumstances. Before starting work, consult the responsible structural engineer, architect or the construction supervisor. The permitted slot depth and width depends on the slot length, wall thickness and the building material used.

 Dust Extraction

Dust which occurs during your work is hazardous to health. That is why the HCE150 must be used with a vacuum cleaner, and a dust mask has to be worn.A suitable wet/dry vacuum cleaner is available as accessory. It can directlybe attached to the connection on the dust hood.

To securely fasten the suction hose, it can be secured against slipping out using the hose fixation.

The hole in the suction hose required for this must be created as follows:
Insert the suction hose into the suction opening of the hood. Mark the insertion depth with a pencil (see arrow Fig.7).

Drill a 6 mm dia. hole in the hose nozzle 13 mm from this mark (line).

When inserting the suction hose pull the ring of the hose fixing and turn the nozzle till the fixation engages.

Overload protection

In order to protect the operator, motor and tool, the wall chaser is equipped with an electronic and thermal overload protection.

Electronic:

To warn the user against an overload of the machine due to too high contact pressure, a LED is attached to the switch grip. It does not light during idle run or at normal load. When the unit is overloaded the LED light is red, in this case, the unit must be stress-relieved. You can continueworking after having stress-relieved and switching OFF and ON the power tool again.

Thermal

In case of permanent overload, a thermocouple protects the motor against destruction. In this case, the tool switches off automatically and can only be restarted after a certain cooling period (approx. 2 minutes). The cooling period depends on the heating of the motor winding and the ambient temperature.

 Care and Maintenance

 Before the beginning of maintenance or repair works you have to disconnect the plug from the mains.

Repairs may be executed only by appropriately qualified and experienced personnel. After every repair the machine has to be inspected by an electric specialist. Due to its design, the machine needs a minimum of care and maintenance. However, the following points always have to be observed:

• Always keep the power tool and the ventilation slots clean.
• During work, please pay attention that no particles get inside the machine.
• In case of failure, a repair has to be carried out by an authorised service workshop.
• Customer service will answer your questions about repair and maintenance of your product as well as spare parts.
• The TYROLIT application advice team will be happy to help you with questions about our products and their accessories.

Environmental Protection

 Raw material recycling instead of waste disposal To avoid damages on transportation, the power tool has to be delivered in a sturdy packing. Packaging as well as unit and accessories are made of recyclable materials and can be disposed accordingly. The tool’s plastic components are marked according to their material. This enables environmentally friendly, differentiated disposal via the available collection facilities.

Only for EU countries

 Do not dispose of electric tools together with household waste material!
In observance of the European Directive 2012/19/EU on waste electrical and electronic equipment and its implementation in accordance with national law, electric tools that have reached the end of their life must be collected separately and returned to an environmentally compatible  recycling facility.

Noise Emission / Vibration

Measured sound values determined according to EN 60745.
Typically the A-weighted noise levels of the product are:
Sound pressure level LpA 83 dB(A)
Sound power level LwA 94 dB(A)
Uncertainty K 3 dB

Wear ear protectors!

Vibration total values ah and uncertainty K determined according to EN 60745:

Vibration emission value ah 2,4 m/s2
Uncertainty K 1,3 m/s2

The declared vibration emission level represents the main applications of the tool. However if the tool is used for different applications, with different accessories or poorly maintained, the vibration emission may differ. This may significantly increase the exposure level over the total working period.

An estimation of the level of expo ure to vibration should also take into account the times when the tool is switched off or when it is running but not actually doing the job. This may significantly reduce the exposure level over the total working period. Identify additional safety measures to protect the operator from the effects of vibration such as: maintain the tool and the accessories, keep the hands warm, organisation of work patterns.

Dust Protection

Dust from material such as paint containing lead, some wood species, minerals and metal may be harmful. Contact with or inhalation of the dust may cause allergic reactions and/or respiratory diseases to the operator or bystanders.Certain kinds of dust are classified as carcinogenic such as oak and beech dust especially in conjunction with additives for wood conditioning (chromate, wood preservative). Material containing asbestos must only be treated by specialists.

• Where the use of a dust extraction device is possible it shall be used.
• To achieve a high level of dust collection, use an industrial vacuum  cleaner (dust class M) for wood and/or minerals together with this tool.
• The work place must be well ventilated.
• The use of dust mask of filter class P2 is recommendend.
