Operate the machine only with the auxiliary han- die 12. Place the auxiliary handle on the clamping collar and tighten with the clamping screw. Damaged mains cables must notbe used. They must be replaced without delay by an authorised servicing agent (heavy rubber sheathed code designation HO7RN-F). 6 Putting into Operation A Check before putting into operation that the mains voltage agrees with the voltage specified on the nameplate of the machine.

Press or release the on/off switch 8. The on/off switch can be locked on with the locking button 7. To release, briefly press and release the on/ off switch 8.

DRILLING - IMPACT DRILLING

For drilling, place the selector 10 in the «ss position. For impact drillng, setto (= The switch-over can bestbe performed ata standstil. Only after the onfoff switch 8 is actuated and the machine starts does the gear box shift to the selected mode. Note: Left rotation when impact driling damages the dril. Switch off the impact mechanism for diamond crown drilling or for mixing work. When hammer drilling, use exclusively drills with hard metal inserts and SDS-Plus shafts. The use of commercial available masonry drils with cylindrical shafts by means ofthe adapter 13 and the normal dril chuck in conjunction with the pneumatic impact mech- anism is not possible. SPEED CONTROL (n With the On/Off switch 8, two speed a] 2

steps can be selected. For hole starting, press the On/Off switch 8 lightly (hole starting step). For full driling performance, press in the On/Off switch 8 completely.

ROTATIONAL DIRECTION SWITCHING

Operate the rotational direction switch 6 only when the machine is ata standstill! L] rare hoid ofthe rotational direction switch 6 on both sides. Right rotation: Setthe rotational direction switch 6 to'R". Left rotation: Setthe rotational direction switch 6 to'L" Important: Press the rotational direction switch 6 in each case to the stop on the housing, i. e. until it can be felt to engage. Ifthe rotational direction switch 6 is set between the positions “R"and “L”, the machine cannot be switched on. 7 Inserting/Removing Tools The tool holder 1 clamps the driling tools without using a tool key. INSERTING TOOLS Before any work on the machine itself, pull the mains plug! Clean and lightly grease the tool shaft Pull back the unlocking collar 3. Insert the tool while tuming into the tool holder until ilatches. Release the unlocking collar. Check whether the tool is firmly seated. Take care that the dust protection cap 2 is not dam- aged. Replace damaged dust protection caps! REMOVING TOOLS Slide the unlocking collar 3 to the rear and pull outthe tool

September 2001 1:20 13 HM 550 English 9 8 Drill Chuck (Accessory) For driling work in metal, wood and plastic with drills that have normal shafts, a drill chuck (13 mm max. chuck opening) is available. The dll chuck is mounted on the adapter (accessory) for screwdriver bits. All common dril chucks with 1/2" x 20 UNF inter- nal threads (13 mm max. chuck opening) can be used

A Before any work on the machine itself, pull the mains plug! Clean the threads of the drill chuck (accessory) and the adapter 13 (accessory). Screw the drill chuck onto the adapter and tighten firmly (approx. 30 Nm). Clamp in a vise for tightening the adapter, for example. Clamp an Allen key in the dll chuck and use itto tighten the chuck. Then lock the adapter in the tool holder the same as à drill. 9 Practical Tips Do not drill into hidden electrical lines or gas and water pipes. Check the area to be worked with à metal detector, for example, before starting. For metal, use only fiawless, sharpened drils; for stone and concrete, only masonry drills with hard metal inserts. Always adaptthe speed to the material to be worked and the diameter of the drill. For precision working with metal and wood, place the machine in à drill stand (accessory). HAMMER- DRILLING Wear protective glasses and hearing protection.

Do not apply to much pressure. The performance is not increased in this manner. For hammer driling, work only with protective glasses, hearing protection and the auxiliary han- dle 12. Check before putting into operation ifthe shift knob 10 is latched in the (= position.

Start driling slowly on the tile. After the tie is drilled through, switch to impact drilling SCREWDRIVING Screwdriver bits can be inserted into the adapter 13 (accessory). Commercially available bits with a hex- agonal dimension of 6.3 mm or 1/4" (DIN 3126, Form C) can be used. The screwdriver bits are held in the adapter with a spring ring. Therefore, use only bits with a notch 10 /Slip Clutch Ithe dilling tool become jammed or get caught, the slip clutch releases Remove the load from the machine immediately by pulling back the driling tool. Always hold the machine tightiy with both hands and assume à secure stance. 11 Maintenance Measures A Before any work on the machine itself, pull the mains plug! Always keep the ventilation slots clean. Wipe off the accessible plastic parts regularly with a cloth without cleaning agent After heavy use over à long period, the machine should be taken to a Kress service location for an inspection and thorough cleaning. 12 Environmental Protection Do not dispose of electric tools together with household waste material! Recycle raw materials instead of dis- posing as waste. The machine, accessories and packa- ging should be sorted for environ- mental friendly recycling. These instructions are printed on recycled paper manufactured without chlorine. The plastic components are labelled for categorised recycling. Subject to change without notice
